Definitions

  • the invention relates to a shielding sleeve for contacting shielding elements between cables and connectors, comprising a spring region with at least one spring element and a sleeve region with a cylindrical and at least partially circumferential extension.
  • Contacts in general have at least one electrically conductive contact section for detachable, temporary or plug-in connection to a corresponding mating contact element and a shaft section adjoining the contact section for fastening an electrical line to the contact.
  • Such a contact, plug-in contact, high-current contact can be implemented in a wide variety of applications, for example for circuit board contacting, in vehicle wiring harness arrangements, on or in a charging plug or charging socket, for example for charging an electrically powered vehicle, etc.
  • EMC electromagnetic compatibility
  • Electromagnetic compatibility means the (largely) absence of influences on other devices and equipment that lead to unwanted or intentional malfunctions of electrical or electronic equipment, for example due to electrical, magnetic or electromagnetic fields and processes. This already includes influences caused by currents or voltages.
  • the European EMC Directive defines electromagnetic compatibility as follows: "the ability of an apparatus, installation or system to operate satisfactorily in the electromagnetic environment, without causing electromagnetic disturbances which would be unacceptable for any equipment, installations or systems present in that environment.” (Source: EU Directive 2014/30/EU Article 3 No. 4 of 26.02.2014).
  • Electromagnetically relevant interference can also come from plugs, connectors, contacts and cables, as these are live. To ensure electromagnetic compatibility, devices, equipment, cables and connectors are often shielded. The shielding of electrical devices, equipment and rooms serves to keep electrical and/or magnetic fields away from them or, conversely, to protect the environment from the fields emanating from the equipment.
  • the shielding devices of cables In the area of connectors, plug contacts and contacts, the shielding devices of cables must be continued without gaps or interruptions to ensure that electromagnetic emissions are reduced or prevented.
  • a coupling impedance is implemented between the inner, current-carrying conductor (core, strand) and the outer cable shield (outer conductor, cable shield) based on the operation of the Faraday cage.
  • electrical connectors are usually overmolded with an electrically conductive sheath or a metallic braid is inserted.
  • the WO 2007/107196 A1 shows a solution in which the outer surface of the contact chamber is completely coated with a thin, electrically conductive layer.
  • the layer thickness is small in relation to the thickness of the contact chamber walls. It is intended that the abutting surfaces on the outside of the contact chamber are shielded with an overlap wall section, which is also coated with a conductive coating on the side facing the abutting surfaces, preferably with the same layer as the outer surface of the contact chamber.
  • a metallization is preferably provided as the conductive layer.
  • the overlap wall section or sections intercept electromagnetic waves emerging through the slots between abutting surfaces that cannot be avoided due to manufacturing technology, and the entry of such radiation into the contact chamber is prevented or at least made more difficult.
  • the overlap wall section represents a kind of labyrinth for electromagnetic radiation.
  • the electrically conductive coated outer surface of the contact chamber also has the function of passing on the shielding from a connection cable connected to the electrical connector to an interface to an application connected via the connector.
  • a sleeve that is spring-loaded in the radial direction can be used, which presses the shielding and outer conductor of the connecting cable radially inwards onto the outer surface of a conductive collar section. It is important that the sleeve has a spring-loaded effect and thus produces a contact force radially inwards from lugs that are spaced apart in the circumferential direction. The lugs press the shielding of the connecting cable onto the outside of the collar section.
  • a spring sleeve can be provided with which the shielding is passed on to the interface of the application.
  • the spring sleeve is pulled over a neck of the contact chamber and is designed in such a way that it springs both radially inwards and radially outwards.
  • springy tabs are provided on the inner and outer circumference of the spring sleeve in the radial direction.
  • the spring sleeve also fulfills the function of tolerance compensation in the interface to the application due to the springy tabs provided on the outer circumference.
  • the spring sleeve When assembled, the spring sleeve is arranged concentrically to the longitudinal center axis of the socket-like contact.
  • a shielded connector arrangement is also available in the DE 101 40 685 C1 disclosed.
  • a cable connection with an inserted plug-in coupling is shown, with one coupling part having a protective sleeve and the other coupling part having two coaxial guide sleeves and a cable entry.
  • the components are connected to one another both electrically and fluidically via fluid seals and subsequent electrical contacts at their transitions.
  • the DE 197 37 321 C2 discloses a single-pole load connector combination with a mounting plug and a loose plug, each of which has a housing made of aluminum, wherein a front end section of the mounting plug can be inserted coaxially into a socket section of the loose plug.
  • An insulating plug insert is arranged in each of the mounting plug and the loose plug, which receives a contact element connected to a connection cable.
  • the mounting plug and the loose plug each have a shielding sheath of the respective connection cable in the form of a hose spring, which creates a conductive connection between the shielding sheath and a screw-in socket screwed into the housing.
  • Another hose spring is inserted into the front socket section of the loose plug, which forms an effectively closed shield of the connector combination when the plugs are plugged into one another.
  • a high-frequency connector for symmetrical, shielded cables is used in the DD 282 783 A5 presented.
  • the connector components have a first and a second spring sleeve with a continuous longitudinal slot and a circumferential projection on the front ends of their inner wall, with one projection engaging in the circumferential groove of the first or second insulating part and with the other projection behind a first or second flange with a pipe socket carrying an external thread, that the first and second metal cylinders sit on the first or second spring sleeve and each strike one end of the first or second spring sleeve with their annular end face pointing against the plugging direction, and that a nut on the external thread of the pipe socket holds the first or second metal cylinder without play and the clamping sleeve arranged on the first metal cylinder with axial play.
  • a socket with a shoulder pointing against the direction of insertion sits on the outer shielding braid of a symmetrical, shielded cable to be connected to the RF connector and is accommodated inside a cylindrical shaft connected to the pipe socket in such a way that the folded-back end of the shielding braid pointing against the direction of insertion is located between the outer wall of the socket and the inner wall of the cylindrical shaft and the cylindrical shaft, the folded-back end of the shielding braid and the socket sitting on the shielding braid of the cable/are crimped together.
  • the spring sleeves, shield sleeves and shield springs available in the state of the art have different disadvantages depending on the design. Many solutions are complex, costly and cannot be produced efficiently due to their multi-part and/or geometric design. If clamping functions are implemented in an integrated manner using the spring sleeves, shield sleeves and shield springs, the fatigue strength requirements are often not met. With known solutions there is also the risk that electrical resistance properties lead to increased power losses.
  • the preamble of claim 1 is reflected in the documents DE 10 2011 102 566 A1 , DE 10 2012 105 258 A1 and EP 0 052 980 A2 revealed.
  • the invention proposes a shielding sleeve according to claim 1.
  • the teaching according to the invention is associated with a number of other advantages, in particular the fatigue strength and permanently maintained spring tension are reliably achieved. This is the result of the creeping processes and relaxation of the spring, which are prevented or minimized due to the roof-shaped and/or triangular shape in the spring area.
  • the increased and permanent pressure on the contact points also supports a reliable and reduced contact resistance over the service life.
  • the temperature resistance and/or the temperature-dependent preload reduction of the spring effect is improved by supporting the contact area via the triangular shape and is therefore less susceptible to high temperatures.
  • the increased contact pressure of the spring blade on the housing of the plug connection or the contact partner of the shield results in a lower electrical resistance in the contact area because possible surface contamination, oxide layers, for example aluminum oxide, are practically penetrated and rubbed through.

Description

Die Erfindung betrifft eine Schirmhülse zur Kontaktierung von Schirmungselementen zwischen Leitungen und Steckverbindern, aufweisend einen Federbereich mit wenigstens einem Federelement und einen Hülsenbereich mit einer zylinderförmigen und wenigstens bereichsweisen Umfangserstreckung.The invention relates to a shielding sleeve for contacting shielding elements between cables and connectors, comprising a spring region with at least one spring element and a sleeve region with a cylindrical and at least partially circumferential extension.

Elektrische Kontaktelemente, Kontaktanordnungen, steck- und lösbare Kabelverbindungselemente sowie dazu geeignete Herstellungsverfahren sind im bekannten Stand der Technik verfügbar.Electrical contact elements, contact arrangements, plug-in and detachable cable connection elements as well as suitable manufacturing processes are available in the known state of the art.

Kontakte im Allgemeinen weisen wenigstens einen elektrisch leitfähigen Kontaktabschnitt zum lösbaren, temporären oder steckenden Verbinden mit einem korrespondierenden Gegenkontaktelement und einen an den Kontaktabschnitt anschließenden Schaftabschnitt zum Befestigen einer elektrischen Leitung an dem Kontakt auf. Ein solcher Kontakt, Steckkontakt, Hochstromkontakt kann in unterschiedlichsten Anwendungen realisiert werden, beispielsweise zur Leiterplattenkontaktierung, in Kabelbaumanordnungen von Fahrzeugen, an oder in einem Ladestecker oder einer Ladebuchse beispielsweise zum Aufladen eines elektrisch angetriebenen Fahrzeugs usw. Verwendung finden.Contacts in general have at least one electrically conductive contact section for detachable, temporary or plug-in connection to a corresponding mating contact element and a shaft section adjoining the contact section for fastening an electrical line to the contact. Such a contact, plug-in contact, high-current contact can be implemented in a wide variety of applications, for example for circuit board contacting, in vehicle wiring harness arrangements, on or in a charging plug or charging socket, for example for charging an electrically powered vehicle, etc.

Je nach Einsatzgebiet sind unterschiedlichste, oft auch kumulativ zu erfüllende Anforderungen gegeben: Zuverlässigkeit, Dauerfestigkeit, Lösbarkeit, reduzierter Widerstand, Resistent gegenüber äußeren Einflüssen und Umweltbedingungen, unempfindlich hinsichtlich Kontaktkorrosion und viele weiter mehr. Ein praktisch immer zu erfüllendes Kriterium ist die elektromagnetische Verträglichkeit (EMV).Depending on the application, there are a wide variety of requirements that must be met, often cumulatively: reliability, fatigue strength, detachability, reduced resistance, resistance to external influences and environmental conditions, insensitive to contact corrosion and many more. One criterion that must practically always be met is electromagnetic compatibility (EMC).

Die elektromagnetische Verträglichkeit bedeutet das (weitgehende) Fehlen von Einwirkungen auf andere Geräte und Einrichtungen, die bei diesen zu ungewollten oder gewollten Funktionsstörungen elektrischer oder elektronischer Betriebsmittel durch z. B. elektrische, magnetische oder elektromagnetische Felder und Vorgänge führen. Darin sind Beeinflussungen durch Ströme oder Spannungen bereits eingeschlossen. Die Europäische EMV-Richtlinie definiert elektromagnetische Verträglichkeit wie folgt: "die Fähigkeit eines Apparates, einer Anlage oder eines Systems, in der elektromagnetischen Umwelt zufriedenstellend zu arbeiten, ohne dabei selbst elektromagnetische Störungen zu verursachen, die für alle in dieser Umwelt vorhandenen Apparate, Anlagen oder Systeme unannehmbar wären." (Quelle: EU-Richtlinie 2014/30/EU Artikel 3 Nr. 4 vom 26.02.2014).Electromagnetic compatibility means the (largely) absence of influences on other devices and equipment that lead to unwanted or intentional malfunctions of electrical or electronic equipment, for example due to electrical, magnetic or electromagnetic fields and processes. This already includes influences caused by currents or voltages. The European EMC Directive defines electromagnetic compatibility as follows: "the ability of an apparatus, installation or system to operate satisfactorily in the electromagnetic environment, without causing electromagnetic disturbances which would be unacceptable for any equipment, installations or systems present in that environment." (Source: EU Directive 2014/30/EU Article 3 No. 4 of 26.02.2014).

Elektromagnetisch relevante Störaussendungen können auch von Steckern, Steckverbindungen Kontakten sowie den Leitungen ausgehen, da diese stromführend sind. Um die elektromagnetische Verträglichkeit sicherzustellen werden Apparate, Geräte, Leitungen, Steckverbinder häufig abgeschirmt. Die Abschirmung elektrotechnischer Geräte, Einrichtungen und Räume dient dazu, auftretende elektrische und/oder magnetische Felder von diesen fernzuhalten oder umgekehrt die Umgebung vor den von der Einrichtung ausgehenden Feldern zu schützen.Electromagnetically relevant interference can also come from plugs, connectors, contacts and cables, as these are live. To ensure electromagnetic compatibility, devices, equipment, cables and connectors are often shielded. The shielding of electrical devices, equipment and rooms serves to keep electrical and/or magnetic fields away from them or, conversely, to protect the environment from the fields emanating from the equipment.

Im Bereich der Steckverbinder, Steckkontakte, Kontaktierungen müssen die Schirmungseinrichtungen von Leitungen lücken- und unterbrechungslos fortgeführt werden, um sicherzustellen, dass elektromagnetische Emissionen reduziert oder verhindert werden.In the area of connectors, plug contacts and contacts, the shielding devices of cables must be continued without gaps or interruptions to ensure that electromagnetic emissions are reduced or prevented.

Um diese Anforderung zu erfüllen sind im Stand der Technik verschiedene Ansätze verfolgt. Grundsätzlich wird eine Kopplungsimpedanz zwischen dem inneren, stromführenden Leiter (Seele, Litze) und der äußeren Kabelschirmung (Außenleiter, Kabelschirm) basierend auf der Wirkungsweise des Faradayschen Käfigs verwirklicht.In order to meet this requirement, various approaches have been pursued in the state of the art. Basically, a coupling impedance is implemented between the inner, current-carrying conductor (core, strand) and the outer cable shield (outer conductor, cable shield) based on the operation of the Faraday cage.

Für eine Vielzahl von Anwendungen ist eine ausreichende Abschirmung der Steckverbinder zur Verbesserung der elektromagnetischen Verträglichkeit notwendig. Zu diesem Zweck werden elektrische Steckverbinder in der Regel mit einer elektrisch leitenden Hülle umspritzt oder ein metallisches Geflecht eingelegt.For a variety of applications, adequate shielding of the connectors is necessary to improve electromagnetic compatibility. For this purpose, electrical connectors are usually overmolded with an electrically conductive sheath or a metallic braid is inserted.

Um die Schirmungselemente der Leitungen, Kabel im Bereich der Steckverbinder zu kontaktieren bzw. diese Kabelabschirmungen lückenlos fortzuführen, können Hülsen, Federhülsen, Schirmhülsen, Schirmfedern eingesetzt sein, die die Schirmungseinrichtungen der Leitungen mit dem Schirmungsmaßnahmen des Steckverbindergehäuses und/oder des zu kontaktierenden Gegensteckers und/oder des zu kontaktierenden Leitung fortführen. Neben der eigentlichen Schirmungsfunktion können additiv und je nach implementierten zusätzlichen Funktionen verschiedene Anforderungen gestellt sein:

  • Aufbringen von Klemm-, Presskräften zur Halterung, Fixierung der Leitung in dem Steckverbindergehäuse,
  • Korrosionsresistenz insbesondere bei aggressivem Umfeld wie beispielsweise Feuchte, Salz, Säure,
  • Dauerfestigkeit und minimierte Relaxierungs- und Kriechvorgänge im Werkstoff der Federhülse,
  • Alterungsbeständigkeit,
  • gute Stromleitungseigenschaft, geringer Widerstand.
In order to contact the shielding elements of the lines, cables in the area of the connectors or to continue these cable shields without gaps, sleeves, spring sleeves, shielding sleeves, shielding springs can be used, which continue the shielding devices of the lines with the shielding measures of the connector housing and/or the mating connector to be contacted and/or the line to be contacted. In addition to the actual shielding function, various additional requirements can be made depending on the additional functions implemented:
  • Applying clamping and pressing forces to hold and fix the cable in the connector housing,
  • Corrosion resistance especially in aggressive environments such as moisture, salt, acid,
  • Fatigue strength and minimized relaxation and creep processes in the spring sleeve material,
  • resistance to aging,
  • good current conduction properties, low resistance.

Die WO 2007/107196 A1 zeigt eine Lösung bei der die Außenfläche der Kontaktkammer vollständig mit einer dünnen, elektrisch leitenden Schicht beschichtet wird. Die Schichtdicke ist klein im Verhältnis zur Dicke der Kontaktkammerwände. Vorgesehen ist, dass die Stoßflächen auf der Außenseite der Kontaktkammer mit einem Überlappungswandabschnitt abzuschirmen, der auf seiner den Stoßflächen zugewandten Seite ebenfalls leitend beschichtet ist, vorzugsweise mit der gleichen Schicht wie die Außenfläche der Kontaktkammer. Bevorzugt wird als leitende Schicht eine Metallisierung vorgesehen. Mit dem Überlappungswandabschnitt bzw. den Überlappungswandabschnitten werden durch die fertigungstechnisch nicht zu vermeidenden Schlitze zwischen aneinander anliegenden Stoßflächen austretende elektromagnetische Wellen abgefangen und der Eintritt derartiger Strahlung in die Kontaktkammer hinein wird verhindert oder zumindest erschwert. Der Überlappungswandabschnitt stellt eine Art Labyrinth für elektromagnetische Strahlung dar. Die elektrisch leitend beschichtete Außenfläche der Kontaktkammer hat neben der Abschirmfunktion auch die Funktion der Weitergabe der Schirmung von einem mit dem elektrischen Steckverbinder verbundenen Anschlusskabel zu einer Schnittstelle zu einer mittels des Steckverbinders verbundenen Applikation.The WO 2007/107196 A1 shows a solution in which the outer surface of the contact chamber is completely coated with a thin, electrically conductive layer. The layer thickness is small in relation to the thickness of the contact chamber walls. It is intended that the abutting surfaces on the outside of the contact chamber are shielded with an overlap wall section, which is also coated with a conductive coating on the side facing the abutting surfaces, preferably with the same layer as the outer surface of the contact chamber. A metallization is preferably provided as the conductive layer. The overlap wall section or sections intercept electromagnetic waves emerging through the slots between abutting surfaces that cannot be avoided due to manufacturing technology, and the entry of such radiation into the contact chamber is prevented or at least made more difficult. The overlap wall section represents a kind of labyrinth for electromagnetic radiation. In addition to the shielding function, the electrically conductive coated outer surface of the contact chamber also has the function of passing on the shielding from a connection cable connected to the electrical connector to an interface to an application connected via the connector.

Zusätzlich abschirmend kann eine in radialer Richtung federnde Hülse verwendet sein, die die Schirmung, Außenleiter des Anschlusskabels radial nach innen auf die Außenfläche eines leitenden Kragenabschnitts drückt. Wichtig ist dabei, dass die Hülse federnde Wirkung und damit die Anpresskraft nach radial innen von in Umfangsrichtung beabstandeten Laschen bewirkt. Die Laschen drücken die Schirmung des Anschlusskabels auf die Außenseite des Kragenabschnitts.For additional shielding, a sleeve that is spring-loaded in the radial direction can be used, which presses the shielding and outer conductor of the connecting cable radially inwards onto the outer surface of a conductive collar section. It is important that the sleeve has a spring-loaded effect and thus produces a contact force radially inwards from lugs that are spaced apart in the circumferential direction. The lugs press the shielding of the connecting cable onto the outside of the collar section.

Eine Federhülse kann vorgesehen sein, mit der die Schirmung an die Schnittstelle der Applikation weitergegeben wird. Die Federhülse ist über einen Hals der Kontaktkammer aufgezogen und derart ausgebildet, dass sie sowohl nach radial innen als auch nach radial außen federt. Hierfür sind am Innenumfang sowie am Außenumfang der Federhülse in radialer Richtung federnde Laschen vorgesehen. Neben der Schirmübergabe erfüllt die Federhülse noch die Funktion des Toleranzausgleichs in der Schnittstelle zur Applikation aufgrund der am Außenumfang vorgesehenen federnden Laschen. Im montierten Zustand ist die Federhülse konzentrisch zu der Längsmittelachse des buchsenartigen Kontaktes angeordnet.A spring sleeve can be provided with which the shielding is passed on to the interface of the application. The spring sleeve is pulled over a neck of the contact chamber and is designed in such a way that it springs both radially inwards and radially outwards. For this purpose, springy tabs are provided on the inner and outer circumference of the spring sleeve in the radial direction. In addition to the shield transfer, the spring sleeve also fulfills the function of tolerance compensation in the interface to the application due to the springy tabs provided on the outer circumference. When assembled, the spring sleeve is arranged concentrically to the longitudinal center axis of the socket-like contact.

An insulating plug insert is arranged in each of the mounting plug and the loose plug, which receives a contact element connected to a connection cable. The mounting plug and the loose plug each have a shielding sheath of the respective connection cable in the form of a hose spring, which creates a conductive connection between the shielding sheath and a screw-in socket screwed into the housing. Another hose spring is inserted into the front socket section of the loose plug, which forms an effectively closed shield of the connector combination when the plugs are plugged into one another.

Eine Buchse mit einem gegen die Steckrichtung weisenden Absatz sitzt auf dem äußeren Schirmungsgeflecht einer an den HF-Steckverbinder anzuschließenden symmetrischen, geschirmten Leitung auf und findet derart im Innern eines an den Rohrstutzen anschließenden Zylinderschaftes Aufnahme, dass zwischen Außenwandung der Buchse und Innenwandung des Zylinderschaftes sich das zurückgestülpte, gegen die Steckrichtung weisende Ende des Schirmungsgeflechtes befindet und der Zylinderschaft, das zurückgestülpte Ende des Schirmungsgeflechts und die auf dem Schirmungsgeflecht der Leitung/aufsitzende Buchse miteinander verquetscht sind.A socket with a shoulder pointing against the direction of insertion sits on the outer shielding braid of a symmetrical, shielded cable to be connected to the RF connector and is accommodated inside a cylindrical shaft connected to the pipe socket in such a way that the folded-back end of the shielding braid pointing against the direction of insertion is located between the outer wall of the socket and the inner wall of the cylindrical shaft and the cylindrical shaft, the folded-back end of the shielding braid and the socket sitting on the shielding braid of the cable/are crimped together.

Die im Stand der Technik verfügbaren Federhülsen, Schirmhülsen, Schirmfedern sind je nach Ausführungsform mit unterschiedlichen Nachteilen behaftet. Viele Lösungen sind durch Mehrteiligkeit und/oder geometrischer Ausbildung komplex, kostennachteilig und nicht rationell herstellbar. Werden Klemmfunktionen mit den Federhülsen, Schirmhülsen, Schirmfedern integrativ verwirklicht sind vielfach die Dauerfestigkeitsanforderungen nicht erfüllt. Auch besteht bei bekannten Lösungen die Gefahr, dass elektrische Widerstandseigenschaften zu erhöhten Verlustleistungen führen.The spring sleeves, shield sleeves and shield springs available in the state of the art have different disadvantages depending on the design. Many solutions are complex, costly and cannot be produced efficiently due to their multi-part and/or geometric design. If clamping functions are implemented in an integrated manner using the spring sleeves, shield sleeves and shield springs, the fatigue strength requirements are often not met. With known solutions there is also the risk that electrical resistance properties lead to increased power losses.

Herkömmlich gestaltete Federhülsen unterliegen innerhalb ihrer Lebensdauer Ermüdungserscheinungen durch Relaxierung und Kriechvorgängen im Werkstoff mit der Folge, dass sich der Anpressdruck an die Kontaktpartner verringert. Folge ist, dass sich der Übergangswiderstand und gleichzeitig die Temperatur an der Feder erhöht. In Grenzfällen kann die Kontaktierung versagen und das System zur Abschaltung gebracht werden.Conventionally designed spring sleeves are subject to fatigue phenomena over their service life due to relaxation and creep processes in the material, which results in a reduction in the contact pressure on the contact partners. This results in an increase in the contact resistance and, at the same time, in the temperature of the spring. In borderline cases, the contact can fail and the system can be shut down.

Es ist Aufgabe der Erfindung Federhülsen, Schirmhülsen, Schirmfedern für Kontaktanordnungen, Kontakte, Steckverbindungen weiterzuentwickeln, sodass die zuvor genannten Nachteile des Standes der Technik wenigstens teilweise reduziert und die funktionalen Anforderungen besser erfüllt werden.It is the object of the invention to further develop spring sleeves, shield sleeves, shield springs for contact arrangements, contacts, plug connections, so that the aforementioned disadvantages of the prior art are at least partially reduced and the functional requirements are better met.

Zur Lösung der Aufgabe schlägt die Erfindung eine Schirmhülse gemäß Anspruch 1.To solve the problem, the invention proposes a shielding sleeve according to claim 1.

Die Erfindung erkennt, dass die geometrische Ausbildung der Schirmfeder geeignet ist nicht nur die Aufgaben

  • der Übertragung des EMV Schirmstroms von dem Leitungsmantel auf das Gehäuse der Steckverbinderstecker und/oder
  • der Fixierung, Arretierung in Form einer Kabelrückzugssicherung zum Schutz vor Abzug der Außenisolierung und/oder
  • der Stromübertragung in der Schirmung zur Realisierung des faradayschen Prinzips im höherfrequenten Bereich bzw. der Erdungsströme
zu lösen, sondern auch die kostengünstige Herstellbarkeit und die reduzierte Teileanzahl durch den integrativen Aufbau von Federbereich und hülsenförmigen Abschnitt zu unterstützten.The invention recognizes that the geometric design of the umbrella spring is suitable not only for the tasks
  • the transfer of the EMC shield current from the cable sheath to the housing of the connector plug and/or
  • the fixation, locking in the form of a cable retraction protection to protect against removal of the outer insulation and/or
  • the current transmission in the shielding to realize the Faraday principle in the higher frequency range or the earthing currents
to solve the problem, but also to support cost-effective manufacturability and the reduced number of parts through the integrated construction of the spring area and the sleeve-shaped section.

Mit der erfindungsgemäßen Lehre sind eine Reihe weiterer Vorteile verbunden, insbesondere ist die Dauerfestigkeit und dauerhaft aufrechterhaltende Federspannung zuverlässig realisiert. Dies ist Folge der Kriechvorgänge und Relaxation der Feder die aufgrund der dachförmigen und/oder dreieckähnlichen Form im Federbereich verhindert bzw. minimiert sind. Durch die erhöhte und dauerhafte Anpressung der Kontaktstellen wird darüber hinaus ein zuverlässiger und reduzierter Übergangswiderstand über die Lebensdauer unterstützt werden. Weiterhin ist die Temperaturbeständigkeit und/oder die temperaturabhängige Vorspannungsreduzierung der Federwirkung durch das Abstützen des Kontaktierungsbereichs über die Dreieckform verbessert und dadurch weniger anfällig für hohe Temperaturen.The teaching according to the invention is associated with a number of other advantages, in particular the fatigue strength and permanently maintained spring tension are reliably achieved. This is the result of the creeping processes and relaxation of the spring, which are prevented or minimized due to the roof-shaped and/or triangular shape in the spring area. The increased and permanent pressure on the contact points also supports a reliable and reduced contact resistance over the service life. Furthermore, the temperature resistance and/or the temperature-dependent preload reduction of the spring effect is improved by supporting the contact area via the triangular shape and is therefore less susceptible to high temperatures.

Durch den erhöhten Anpressdruck der Federlamelle an das Gehäuse der Steckverbindung bzw. des Kontaktierungspartners der Schirmung ergibt sich ein geringerer elektrischer Widerstand im Kontaktierungsbereich dadurch, dass mögliche Oberflächenverunreinigungen, Oxydschichten praktisch durchdrungen, durchgerieben werden, beispielsweise Aluminiumoxyd.The increased contact pressure of the spring blade on the housing of the plug connection or the contact partner of the shield results in a lower electrical resistance in the contact area because possible surface contamination, oxide layers, for example aluminum oxide, are practically penetrated and rubbed through.

Figur 1 bildet die perspektivische Ansicht auf ein erstes Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20 ab. Der Federbereich 10 und der Hülsenbereich 20 sind einstückig ausgebildet und basierend auf einem Halbzeugflach 100, vorzugsweise durch Umformung, hergestellt. Figure 1 shows the perspective view of a first embodiment of the shielding sleeve 1 according to the invention with a spring region, spring element region 10 and a sleeve region 20. The spring region 10 and the sleeve region 20 are formed in one piece and are manufactured based on a semi-finished flat 100, preferably by forming.

Der Hülsenbereich 20 ist zylinderförmig gestaltet und dadurch aufsteckkompatibel zu einer Leitung, Kabel mit einer inneren Seele und einer durch Isolationsmaterial elektrisch getrennten Schirmung meist in Form eines Metallgewebes. Gegenüberliegend zum Federelementebereich 10 und endseitig kann der Hülsenbereich 20 eine oder eine Mehrzahl von Abkantungen 21 aufweisen. Durch die wenigstens eine Abkantung 21 liegt ein mechanischer Anschlag vor der den Aufschiebeweg der Schirmhülse 1 auf eine Leitung begrenzt und die definierte Lage der Schirmhülse 1 auf der Leitung unterstützt.The sleeve area 20 is cylindrical and is therefore compatible with a cable with an inner core and a shield that is electrically separated by insulating material, usually in the form of a metal mesh. Opposite the spring element area 10 and at the end, the sleeve area 20 can have one or a plurality of bevels 21. The at least one bevel 21 provides a mechanical stop that limits the sliding path of the shielding sleeve 1 onto a cable and supports the defined position of the shielding sleeve 1 on the cable.

Die in Figur 1 gezeigte Schirmhülse 1 ist im Rahmen einer möglichen Ausgestaltung der Erfindung im Bereich des Hülsenabschnittes 20 segmentartig gestaltet. Durch Verformung, Umformung des vorzugsweise flächigen Ausgangsmaterials ist wenigstens ein Segment 22, vorzugsweise eine Mehrzahl von Segmenten 22 im zylinderförmigen Bereich des Hülsenabschnittes 20 gebildet. In dem gezeigten Beispiel sind Segmente 22 am gesamten Umfang des Hülsenabschnittes 20 vorhanden.The in Figure 1 The shielding sleeve 1 shown is designed in a segment-like manner in the area of the sleeve section 20 within the scope of a possible embodiment of the invention. By deforming and reshaping the preferably flat starting material, at least one segment 22, preferably a plurality of segments 22, is formed in the cylindrical area of the sleeve section 20. In the example shown, segments 22 are present on the entire circumference of the sleeve section 20.

Figur zeigt 2 die Schnittdarstellung der Vorderansicht auf das erste Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20 aus Figur 1. Die Segmente 22 sind einstückige Elemente der Schirmhülse und erstrecken sich vorzugsweise über die gesamte axiale Länge des Hülsenabschnittes. Die segmentierte Gestaltung des Hülsenabschnittes 20 macht es möglich, dass jeweils endseitig der axialen Segmentlängserstreckung eine Abkantung 21 und/oder ein Federelement 13 angeordnet werden kann.Figure 2 shows the sectional view of the front view of the first embodiment of the shielding sleeve 1 according to the invention with a spring area, spring element area 10 and a sleeve area 20 made of Figure 1 The segments 22 are one-piece elements of the shielding sleeve and preferably extend over the entire axial length of the sleeve section. The segmented design of the sleeve section 20 makes it possible for a bevel 21 and/or a spring element 13 to be arranged at each end of the axial segment length.

Das wenigstens eine Federelement 13 dieses ersten Ausführungsbeispiels ist durch einen ersten und wenigsten einen zweiten Schenkel, Federschenkel 12 gebildet. Der erste und der wenigstens eine zweite Schenkel 12 sind zueinander derart angeordnet, dass sich eine dachförmige Geometrie ausbildet. Dieses exemplarische Ausführungsbeispiel bildet zusammen mit einem dritten Schenkel 12, der sich mit axialer Erstreckung an den Hülsenabschnitt 20 anschließt, eine dreieckähnliche Grundform.The at least one spring element 13 of this first embodiment is formed by a first and at least one second leg, spring leg 12. The first and the at least one second leg 12 are arranged relative to one another in such a way that a roof-shaped geometry is formed. This exemplary embodiment forms a triangular basic shape together with a third leg 12, which adjoins the sleeve section 20 with an axial extension.

Durch die dachförmige und/oder dreieckähnliche Form im Federbereich sind Kriechvorgänge und Relaxation der Feder verhindert bzw. minimiert, mit der Folge, dass die Dauerfestigkeit gesteigert und/oder die Federkraft und Anpresskraft der Kontaktstellen dauerhaft weitgehend gleichbleibend ist.The roof-shaped and/or triangular shape in the spring area prevents or minimizes creeping processes and relaxation of the spring, with the result that the fatigue strength is increased and/or the spring force and contact pressure of the contact points remain largely constant over the long term.

Endseitig eines Schenkels 12 kann eine Rundung, Kantung 11 gebildet sein. Die Rundung 11 ermöglicht, besser als ein stumpfer Auslauf des Schenkels 12, die gleitende Relativbewegung auf der jeweiligen Anlagefläche bei Verformungen des Federelementes 13 und/oder die Abstützung des Federelementes 13 über die Kontaktanlagestelle der Rundung, Kantung 11 an der jeweiligen Anlagefläche, die in dem gezeigten Ausführungsbeispiel die äußere Mantelfläche des Hülsenbereiches ist.A rounding or edging 11 can be formed at the end of a leg 12. The rounding 11 enables, better than a blunt end of the leg 12, the sliding relative movement on the respective contact surface in the event of deformations of the spring element 13 and/or the support of the spring element 13 via the contact point of the rounding or edging 11 on the respective contact surface, which in the embodiment shown is the outer surface of the sleeve area.

Figur 3 umfasst die Schnittdarstellung der Vorderansicht des ersten Ausführungsbeispiels der erfindungsgemäßen Schirmhülse 1 innerhalb einer montierten und gesteckten Steckverbindung. Die Schirmhülse 1 ist auf die Leitung 200 aufgeschoben und umfasst einen Abschnitt der äußeren Isolierung 204. Durch die an der äußeren Isolierung 204 stirnseitig anliegende Abkantung 21 ist die axiale Lage der Schirmhülse 1 in Aufschieberichtung mechanisch definiert bzw. festgelegt. Figure 3 includes the sectional view of the front view of the first embodiment of the shielding sleeve 1 according to the invention within an assembled and plugged-in plug connection. The shielding sleeve 1 is pushed onto the cable 200 and includes a section of the outer insulation 204. The axial position of the shielding sleeve 1 in the sliding direction is mechanically defined or fixed by the bevel 21 resting on the front side of the outer insulation 204.

Die zylinderähnliche Außenfläche des Hülsenabschnittes 20 ist wenigstens bereichsweise in elektrisch leitendem Kontakt mit der Leitungsschirmung 203. Zu diesem Zweck ist die die Leitungsschirmung 203 durch vorherige Entfernung eines Bereiches der äußeren Isolation 204 freigelegt und umgeschlagen.The cylinder-like outer surface of the sleeve section 20 is at least partially in electrically conductive contact with the cable shield 203. For this purpose, the cable shield 203 is exposed and folded over by previously removing a portion of the outer insulation 204.

Der Federelementebereich 10 der Schirmhülse 1 ist wenigstens bereichsweise und elastisch und ggf. auch plastisch durch eine Stauchstrecke in radialer Richtung verformt, sodass durch die elastischen Rückstelleigenschaften des Federelementebereichs 10 eine kontaktierend wirkende Kraft auf den Kontaktpartner - hier die innere Gehäusefläche des Steckverbindersteckers - ausgeübt wird. Das wenigstens eine Federelement 13 des Federbereiches 10 liegt mit seiner endseitigen Rundung 11 an der Außenfläche des Hülsenbereiches 20 an und stützt sich auf diese Weise daran ab.The spring element area 10 of the shielding sleeve 1 is deformed at least in some areas elastically and possibly also plastically by a compression distance in the radial direction, so that a contacting force is exerted on the contact partner - here the inner housing surface of the connector plug - by the elastic recovery properties of the spring element area 10. The at least one spring element 13 of the spring area 10 rests with its end rounding 11 on the outer surface of the sleeve area 20 and is supported on it in this way.

Das gezeigte Ausführungsbeispiel verfügt über eine Ausbuchtung, Kalotte 14 im Giebelabschnitt der dachförmigen Anordnung des Federelementes 13. Auf diese Weise können zwei Vorteile erreicht werden:

  1. 1. Durch die verkleinerte Kontaktfläche infolge der sich ergebenden Punktkontaktfläche ist die Flächenpressung stark gesteigert und eine besonders zuverlässige Kontaktierung unterstützt;
  2. 2. die Ausbuchtung 14 beeinflusst das elastische Federverhalten infolge der sich ergebenden Kerbspannung positiv, d. h. der elastische Verformungsanteil ist im Vergleich zur Situation ohne Ausbuchtung 14 gesteigert.
The embodiment shown has a bulge, calotte 14 in the gable section of the roof-shaped arrangement of the spring element 13. In this way, two advantages can be achieved:
  1. 1. Due to the reduced contact area resulting from the point contact area, the surface pressure is greatly increased and particularly reliable contact is supported;
  2. 2. the bulge 14 has a positive effect on the elastic spring behavior due to the resulting stress concentration, ie the elastic deformation component is increased compared to the situation without bulge 14.

Figur 4 illustriert die perspektivische Ansicht auf ein zweites Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20. Der Erfindungsgedanke ist hier umgesetzt durch eine Mehrzahl dachförmiger Federlamellen, Federelemente 13, die in axial fortlaufender Erstreckung am Hülsenbereich 20 ausgebildet sind. Eine dreieckförmige geometrische Situation der Federelemente 13 des Federbereiches 10 wird in montiertem Zustand durch das Zusammenwirken mit der äußeren Isolation 204 des elektrisch leitenden Kabels 200 erreicht durch ein Anlegen der Federlamellen 13 an die äußere Isolation 204. Realisiert wird die Anlage durch Kontaktflächen endseitig der Federlamellen 13 über die jeweils ausgebildete Rundung, Kantung 11. Figure 4 illustrates the perspective view of a second embodiment of the shielding sleeve 1 according to the invention with a spring region, spring element region 10 and a sleeve region 20. The inventive concept is implemented here by a plurality of roof-shaped spring lamellae, spring elements 13, which are formed in an axially continuous extension on the sleeve region 20. A triangular geometric situation of the spring elements 13 of the spring region 10 is achieved in the assembled state by the interaction with the outer insulation 204 of the electrically conductive cable 200 by placing the spring lamellae 13 on the outer insulation 204. The system is realized by contact surfaces at the end of the spring lamellae 13 via the respective rounding, edging 11.

Die dreieckförmige geometrische Situation des Federelementebereiches 10 in montiertem Zustand zeigt Figur 5. Die abgebildete Schnittdarstellung der Vorderansicht des zweiten Ausführungsbeispiels der erfindungsgemäßen Schirmhülse 1 innerhalb einer montierten und gesteckten Steckverbindung nutzt die zuvor beschriebenen Vorteile der Erfindung durch die dreieckförmige geometrische Situation des Federelementebereiches 10.The triangular geometric situation of the spring element area 10 in the assembled state shows Figure 5 The illustrated sectional view of the front view of the second embodiment of the shielding sleeve 1 according to the invention within an assembled and plugged-in connector utilizes the previously described advantages of the invention through the triangular geometric situation of the spring element area 10.

Figur 6 umfasst die perspektivische Ansicht auf ein drittes Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20. Abweichend von dem ersten Ausführungsbeispiel der Erfindung ist hier die Endseite der Federelemente 13 geometrisch verändert. Figure 6 includes the perspective view of a third embodiment of the shielding sleeve 1 according to the invention with a spring region, spring element region 10 and a sleeve region 20. Deviating from the first embodiment of the invention, the end side of the spring elements 13 is geometrically changed here.

Endseitig eines Schenkels 12 kann eine Rundung, Kantung 11 ausgebildet sein, welche abweichend von dem ersten Ausführungsbeispiel in Richtung der Innenseite der Schirmhülse 1 gerichtet ist. Auf diese Weise wird die Anlagefläche durch einen endseitigen Federelementbereich erreicht, der weitgehend parallel oder planparallel zu der Anlagefläche an dem Hülsenbereich 20 ist. Auch auf diese Weise und funktionell vergleichbar zu der Ausgestaltung der Rundung 11 ermöglicht dies besser als ein stumpfer Auslauf des Schenkels 12 die gleitende Relativbewegung auf der jeweiligen Anlagefläche bei Verformungen des Federelementes 13.A rounded portion or edge 11 can be formed at the end of a leg 12, which, in contrast to the first embodiment, is directed towards the inside of the shielding sleeve 1. In this way, the contact surface is achieved by an end-side spring element area that is largely parallel or plane-parallel to the contact surface on the sleeve area 20. In this way too, and functionally comparable to the design of the rounded portion 11, this enables the sliding relative movement on the respective contact surface when the spring element 13 is deformed better than a blunt end of the leg 12.

Figur 7 zeigt die Schnittdarstellung der Vorderansicht auf das dritte Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 aus Figur 6 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20. Analog zum ersten Ausführungsbeispiel ist auch hier das wenigstens eine Federelement 13 des dritten Ausführungsbeispiels durch einen ersten und wenigsten einen zweiten Schenkel, Federschenkel 12 gebildet. Der erste und der wenigstens eine zweite Schenkel 12 sind zueinander derart angeordnet, dass sich eine dachförmige Geometrie ausbildet. Dieses exemplarische Ausführungsbeispiel bildet zusammen mit einem dritten Schenkel 12, der sich mit axialer Erstreckung an den Hülsenabschnitt 20 anschließt, eine dreieckähnliche Grundform. Figure 7 shows the sectional view of the front view of the third embodiment of the shielding sleeve 1 according to the invention from Figure 6 with a spring region, spring element region 10 and a sleeve region 20. Analogous to the first embodiment, the at least one spring element 13 of the third embodiment is also formed by a first and at least one second leg, spring leg 12. The first and the at least one second leg 12 are arranged relative to one another in such a way that a roof-shaped geometry is formed. This exemplary embodiment forms a triangular basic shape together with a third leg 12, which adjoins the sleeve section 20 with an axial extension.

Durch die dachförmige und/oder dreieckähnliche Form im Federbereich sind Kriechvorgänge und Relaxation der Feder verhindert bzw. minimiert, mit der Folge, dass die Dauerfestigkeit gesteigert und/oder die Federkraft und Anpresskraft der Kontaktstellen dauerhaft weitgehend gleichbleibend ist.The roof-shaped and/or triangular shape in the spring area prevents or minimizes creeping processes and relaxation of the spring, with the result that the fatigue strength is increased and/or the spring force and contact pressure of the contact points remain largely constant over the long term.

Figur 8 verdeutlicht die Schnittdarstellung der Vorderansicht des dritten Ausführungsbeispiels der erfindungsgemäßen Schirmhülse 1 innerhalb einer montierten und gesteckten Steckverbindung. Figure 8 illustrates the sectional view of the front view of the third embodiment of the shielding sleeve 1 according to the invention within an assembled and plugged connector.

Figur 9 zeigt die perspektivische Ansicht auf ein viertes Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20. Der Erfindungsgedanke ist hier umgesetzt durch eine geometrische Variante des zweiten Ausführungsbeispiels, das in Figur 4 und 5 gezeigt ist. Das vierte Ausführungsbeispiel umfasst eine Mehrzahl dachförmiger Federlamellen, Federelemente 13, die in axial fortlaufender Erstreckung am Hülsenbereich 20 ausgebildet sind. Figure 9 shows the perspective view of a fourth embodiment of the shielding sleeve 1 according to the invention with a spring area, spring element area 10 and a sleeve area 20. The inventive concept is implemented here by a geometric variant of the second embodiment, which in Figure 4 and 5 The fourth embodiment comprises a plurality of roof-shaped spring lamellae, spring elements 13, which are formed in an axially continuous extension on the sleeve region 20.

Die dachförmige geometrische Gestaltung ist ergänzt um eine Abflachung 15 und ersetzt die Dachspitze innerhalb der Dachform. Die Abflachung 15 modifiziert das federelastische Verhalten der Federlamellen 13 je nach Ausgestaltung in unterschiedlicher Weise.The roof-shaped geometric design is supplemented by a flattening 15 and replaces the roof peak within the roof shape. The flattening 15 modifies the spring-elastic behavior of the spring slats 13 in different ways depending on the design.

Eine Möglichkeit besteht darin, dass die Federkennlinie in Richtung einer flacheren Federkennlinie im Vergleich zu einer Federlamelle 13 mit Dachspitze gemäß der zweiten Ausführungsform, wie in Figur 4 und 5 gezeigt, modifiziert wird. Die flachere Federkennlinie resultiert in einem größeren Federweg bei gleicher Krafteinwirkung im Vergleich zu einer Federlamelle 13 mit Dachspitze. Dies ist Ergebnis der verringerten Biegesteifigkeit der Federlamelle 13 und/oder des geänderten Kraftangriffpunktes, realisiert an der Ausbuchtung 14 infolge der Längenverhältnisse der Schenkel 12.One possibility is that the spring characteristic curve is directed towards a flatter spring characteristic curve compared to a spring lamella 13 with a roof peak according to the second embodiment, as in Figure 4 and 5 shown, is modified. The flatter spring characteristic curve results in a greater spring travel with the same force application compared to a spring lamella 13 with a roof peak. This is the result of the reduced bending stiffness of the spring lamella 13 and/or the changed force application point, realized at the bulge 14 as a result of the length ratios of the legs 12.

Eine dreieckförmige geometrische Situation der Federelemente 13 des Federbereiches 10 mit Abflachung 15 wird auch mit dem vierten Ausführungsbeispiel in montiertem Zustand durch das Zusammenwirken mit der äußeren Isolation 204 des elektrisch leitenden Kabels 200 erreicht durch ein Anlegen der Federlamellen 13 an die äußere Isolation 204. Realisiert wird die Anlage durch Kontaktflächen endseitig der Federlamellen 13 über die jeweils ausgebildete Rundung, Kantung 11.A triangular geometric situation of the spring elements 13 of the spring area 10 with flattening 15 is also achieved with the fourth embodiment in the assembled state by the interaction with the outer insulation 204 of the electrically conductive cable 200 by applying the spring lamellae 13 to the outer insulation 204. The system is realized by contact surfaces at the end of the spring lamellae 13 via the respective rounding, edging 11.

Figur 10 umfasst die Schnittdarstellung der Vorderansicht auf das vierte Ausführungsbeispiel der erfindungsgemäßen Schirmhülse 1 mit einem Federbereich, Federelementebereich 10 und einem Hülsenbereich 20 innerhalb einer montierten und gesteckten Steckverbindung und nutzt die zuvor beschriebenen Vorteile der Erfindung durch die dreieckförmige geometrische Situation des Federelementebereiches 10 in Verbindung mit der Abflachung 15 zur gezielten Modifikation des federelastischen Verhaltens der Federlamellen 13, je nach Ausgestaltung in unterschiedlicher Weise. Die gezeigte geometrische Ausbildung verfügt über einen längeren Schenkel 12 zwischen Hülsenbereich 20 und Abflachung 15 als die Länge des Schenkels 12 zwischen Abflachung 15 und Rundung 11. Dadurch ist eine flache Federkennlinie realisiert, d. h. die Elastizität, Verformungsfähigkeit ist gesteigert und der Federweg ist im Vergleich mit der Ausbildung einer Dachspitze bei gleicher resultierender radial zur Schirmhülse 1 wirkenden Krafteinwirkung erhöht. Figure 10 includes the sectional view of the front view of the fourth embodiment of the shielding sleeve 1 according to the invention with a spring region, spring element region 10 and a sleeve region 20 within an assembled and plugged-in plug connection and uses the previously described advantages of the invention through the triangular geometric situation of the spring element region 10 in conjunction with the flattened area 15 for the targeted modification of the spring-elastic behavior of the spring lamellae 13, in different ways depending on the design. The geometric design shown has a longer leg 12 between the sleeve region 20 and the flattened area 15 than the length of the leg 12 between the flattened area 15 and the rounding 11. This results in a flat spring characteristic curve, ie the elasticity and deformability are increased and the spring travel is increased compared to the design of a roof peak with the same resulting force acting radially to the shielding sleeve 1.

Figur 11 zeigt die Draufsicht auf ein exemplarisches flächiges Halbzeug 100 zur Herstellung einer erfindungsgemäßen Schirmhülse 1. Das vorzugsweise als Stanzteil vorliegende Halbzeug ist durch die Konturgebung vorbereitet für den nachfolgenden Umformungsprozess durch Abkanten, Falten. Geeignete Werkstoffe müssen sowohl elektrisch leitend als auch umformfähig und federelastische Eigenschaften aufweisen. In Betracht kommen u. a. Kupfer-Nickel-Legierungen, welche für die Korrosionsbeständigkeit optional feuerverzinnt sein können, beispielsweise CuNiSiMg R650. Figure 11 shows the top view of an exemplary flat semi-finished product 100 for producing a shielding sleeve 1 according to the invention. The semi-finished product, which is preferably in the form of a stamped part, is prepared by the contouring for the subsequent forming process by bending and folding. Suitable materials must be electrically conductive, formable and have spring-elastic properties. Examples of suitable materials include copper-nickel alloys, which can optionally be hot-dip tinned for corrosion resistance, for example CuNiSiMg R650.
