Description

Die vorliegend Erfindung betrifft einen Steckverbinder mit einem Außenleiterteil, welches zum elektrischen und mechanischem Verbinden mit einem Außenleiter eines Kabels ausgebildet ist sowie eine elektromagnetische Abschirmung des Steckverbinders ausbildet, mit einem Isolierteil, welches zum Halten mindestens eines Innenleiterteil an einer vorbestimmten Position relativ zum Außenleiterteil ausgebildet ist, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a connector having an outer conductor part, which is designed for electrical and mechanical connection to an outer conductor of a cable and forms an electromagnetic shield of the connector, with an insulating part, which is designed to hold at least one inner conductor part at a predetermined position relative to the outer conductor part , according to the preamble of claim 1.

Aus der US 5 489 222 ist ein Miniatursteckverbinder mit einem Kontakt, welcher gegen Verdrehen gesichert ist, bekannt. Der Steckverbinder weist ein Außenleiterteil, ein Isolierteil und einen elektrischen Kontakt auf. Das Außenleiterteil ist zum elektrischen und mechanischen Verbinden mit einem Koaxialkabel ausgebildet und weist an dessen Innenfläche Rippen auf. Ein Innendurchmesser des Außenleiterteils ist etwas größer als ein Außendurchmesser des Isolierteils und vier Rippen erheben sich radial einwärts von der Innenfläche des Außenleiterteils. Diese vier Rippen bilden einen Presssitz für das Innenleiterteil aus, so dass eine Drehung des Isolierteils relativ zum Außenleiterteil verhindert ist.From the US 5,489,222 is a miniature connector with a contact which is secured against rotation known. The connector has an outer conductor part, an insulating part and an electrical contact. The outer conductor part is designed for electrical and mechanical connection to a coaxial cable and has ribs on its inner surface. An inner diameter of the outer conductor part is slightly larger than an outer diameter of the insulating part and four ribs rise radially inward from the inner surface of the outer conductor part. These four ribs form a press fit for the inner conductor part, so that rotation of the insulating part is prevented relative to the outer conductor part.

Aus der US 5 145 412 ist ein BNC-Winketsteckverbinder, welcher ein Gehäuses zum Auflöten auf eine Platine aufweist, in dem ein Außenleiterteil angeordnet ist, bekannt. In dem Außenleiterteil ist ein Isolierteil angeordnet, welches einen Innenleiter hält. Das Außenleiterteil weist eine Umfangsnut auf, die an einem Ende des Außenleiterteils mit reduziertem Durchmesser ausgebildet ist. Innerhalb dieser Umfangsnut sind diametral gegenüberliegende Erhebungen ausgebildet. Ein C-förmiges Federmetallband mit einem Paar von Ausnehmungen ist in die Umfangsnut eingesetzt, so dass die Nut eine axiale Bewegung des Federmetallbandes blockiert. Die Ausnehmungen des Federmetallbandes nehmen die Erhebungen des Außenleiterteils auf, um das Federmetallband in der Umfangsnut zu fixieren und eine Antirotationsfunktion innerhalb der Umfangsnut zur Verfügung zu stellen. Somit ist eine Verdrehsicherung für das Federmetallband relativ zum Außenleiterteil realisiert. Weiterhin ist über ein Zusammenwirken einer flachen Oberfläche auf dem Außenleiterteil und einer entsprechenden flachen Fläche innerhalb des Gehäuses eine Verdrehsicherung für das Außenleiterteil relativ zum Gehäuse realisiert. Es ist jedoch keine Verdrehsicherung für das Isolierteil vorgesehen.From the US 5 145 412 is a BNC Winket connector, which has a housing for soldering onto a circuit board, in which an outer conductor part is arranged, known. In the outer conductor part an insulating part is arranged, which holds an inner conductor. The outer conductor part has a circumferential groove formed at one end of the reduced diameter outer conductor part. Within this circumferential groove diametrically opposite elevations are formed. A C-shaped spring metal band with a pair of recesses is inserted into the circumferential groove so that the groove blocks axial movement of the spring metal band. The recesses of the Federmetallbandes take on the elevations of the outer conductor part to fix the Federmetallband in the circumferential groove and to provide an anti-rotation function within the circumferential groove. Thus, a rotation for the spring metal band is realized relative to the outer conductor part. Furthermore, an anti-rotation device for the outer conductor part is realized relative to the housing via an interaction of a flat surface on the outer conductor part and a corresponding flat surface within the housing. However, there is no rotation for the insulating provided.

Aus der US 5 011 426 ist eine Steckverbinderanordnung mit einem Stecker mit einem Kunststoffgehäuse und einer Buchse bekannt. Das Kunststoffgehäuse weist Antirotationzapfen auf. Es ist jedoch kein Außenleiterteil vorgesehen, welches zum elektrischen und mechanischem Verbinden mit einem Außenleiter eines Kabels ausgebildet wäre.From the US 5 011 426 a connector assembly with a plug with a plastic housing and a socket is known. The plastic housing has anti-rotation pins. However, no outer conductor part is provided, which would be designed for electrical and mechanical connection to an outer conductor of a cable.

Aus der US 5 453 025 ist ein elektrischer Steckverbinder mit einem Außenleiterteil, einem Isolierteil, welches in einer Axialbohrung des Außenleiterteils angeordnet ist, und einem Innenleiter, welcher in einer Axialbohrung des Isolierteils angeordnet ist, bekannt. Weiterhin ist eine Verdrehsicherung für den Innenleiter relativ zum Isolierteil sowie eine Verdrehsicherung für das Isolierteil relativ zum Außenleiterteil vorgesehen. An der Innenseite des Außenleiterteils sind Erhebungen angeordnet, die sich beim Einschieben des Isolierteils in den weicheren Werkstoff des Isolierteils eingraben. Es ist kein Gehäuse vorgesehen, in dem das Außenleiterteil und das Isolierteil angeordnet wären.From the US 5,453,025 is an electrical connector with an outer conductor part, an insulating part, which is arranged in an axial bore of the outer conductor part, and an inner conductor, which is arranged in an axial bore of the insulating part known. Furthermore, an anti-rotation device for the inner conductor relative to the insulating part and an anti-rotation for the insulating part is provided relative to the outer conductor part. On the inside of the outer conductor part elevations are arranged, which dig when inserting the insulating part in the softer material of the insulating part. There is no housing provided in which the outer conductor part and the insulating part would be arranged.

Aus der US 7 635 283 B1 ist ein Steckverbinder für ein Koaxialkabel, welches einen Innenleiter, einen Außenleiter und ein dazwischen angeordneten Dielektrikum aufweist, bekannt. Der Steckverbinder weist eine rückseitige Gewindemutter mit Innengewinde auf, welche ein rückwärtiges Ende eines mit Außengewinde aufnimmt. Das Steckverbindergehäuse weist eine Ausnehmung zur Aufnahme eines elektrisch leitenden, komprimierbaren Ringes auf. Der Ring drückt den Außenleiter des Koaxialkabels gegen einen rampenförmigen Wandabschnitt der Gewindemutter, wenn das Steckverbindergehäuse und die Gewindemutter miteinander verschraubt werden. Diese Andruckfunktion des Ringes stellt eine elektrisch leitende Verbindung zwischen dem Außenleiter des Koaxialkabels und dem rampenförmigen Wandabschnitt sicher, indem eine konstante Kontaktkraft zur Verfügung steht. Weiterhin stellt der Ring eine Verdrehsicherung für das Koaxialkabel relativ zum Steckverbindergehäuse und zur Gewindemutter zur Verfügung. Eine Verdrehsicherung für das Isolierteil des Steckverbinders ist nicht vorgesehen.From the US Pat. No. 7,635,283 B1 is a connector for a coaxial cable having an inner conductor, an outer conductor and a dielectric disposed therebetween known. The connector has a rear threaded nut Internal thread, which receives a rear end of an externally threaded. The connector housing has a recess for receiving an electrically conductive, compressible ring. The ring presses the outer conductor of the coaxial cable against a ramped wall portion of the threaded nut when the connector housing and the threaded nut are bolted together. This pressure function of the ring ensures an electrically conductive connection between the outer conductor of the coaxial cable and the ramp-shaped wall section by providing a constant contact force. Furthermore, the ring provides an anti-twist device for the coaxial cable relative to the connector housing and the threaded nut. An anti-rotation device for the insulating part of the connector is not provided.

AUs der US 2008/0160836 A1 ist ein Kabelsteckverbinder mit mehreren koaxial zueinander angeordneten Kontakten, zwischen denen jeweils ein Isolator angeordnet ist, bekannt. Zwei der Kontakte weisen an deren Innenseite, die einem der Isolatoren zugewandt ist, jeweils ein Antirotationselement auf, welches als Innenverzahnung oder Innengewinde ausgebildet ist. Diese Innenverzahnung drückt in die jeweiligen Isolatoren. So ist eine Drehbewegung von diesen zwei Kontakt relativ zu einem innersten Kontakt vermieden, wenn der Stecker in einen passenden Gegenstecker eingesteckt und gedreht wird. Das Antirotationselement ist an Innenseiten von Leiterteilen ausgebildet und greift daher nicht durch ein Außenleiterteil hindurch. Weiterhin ist kein Gehäuse vorgesehen, in dem die Kontakte und Isolatoren angeordnet wären. Weiterhin ist keiner der Kontakte derart ausgebildet, dass er eine elektromagnetische Abschirmung des Steckverbinders ausbilden könnte.From the US 2008/0160836 A1 is a cable connector with a plurality of coaxially arranged contacts, between each of which an insulator is arranged known. Two of the contacts have on their inner side, which faces one of the insulators, in each case an anti-rotation element, which is designed as internal toothing or internal thread. This internal toothing presses into the respective insulators. Thus, a rotational movement of these two contacts is avoided relative to an innermost contact when the plug is inserted and rotated in a mating mating connector. The anti-rotation element is formed on inner sides of ladder parts and therefore does not engage through an outer conductor part. Furthermore, no housing is provided in which the contacts and insulators would be arranged. Furthermore, none of the contacts is designed such that it could form an electromagnetic shield of the connector.

Bei einem Steckverbinder der o.g. Art ist es erfindungsgemäß vorgesehen, dass ein Gehäuse vorgesehen ist, in dem das Außenleiterteil und das Isolierteil angeordnet sind, wobei eine Verdrehsicherung vorgesehen ist, welche drehfest mit dem Gehäuse verbunden ist und durch das Außenleiterteil hindurch in das Isolierteil derart eingreift, dass das Isolierteil und das Gehäuse über die Verdrehsicherung drehfest miteinander verbunden istIn a connector of o.g. It is inventively provided that a housing is provided, in which the outer conductor part and the insulating part are arranged, wherein a rotation is provided, which is rotatably connected to the housing and engages through the outer conductor part into the insulating part such that the insulating part and the housing is rotatably connected to each other via the rotation

Dies hat den Vorteil, dass hinsichtlich der Verdrehsicherung des Isolierteils innerhalb des Steckverbinders eine Toleranzkette verkürzt ist, da das Außenleiterteil für die Verdrehsicherung des Isolierteils überbrückt ist.This has the advantage that in terms of the rotation of the insulating part within the connector, a tolerance chain is shortened, since the outer conductor part is bridged for the rotation of the insulating part.

Eine besonders funktionssichere und einfach zu montierende Verdrehsicherung erzielt man dadurch, dass die Verdrehsicherung als Ring, insbesondere C-Ring, ausgebildet ist, welcher das Außenleiterteil an seinem Außenumfang umgreift und einen sich radial nach innen erhebenden Stift aufweist, welcher durch das Außenleiterteil hindurch in das Isolierteil eingreift.A particularly reliable and easy to install anti-rotation is achieved in that the rotation is formed as a ring, in particular C-ring, which engages around the outer conductor part on its outer circumference and has a radially inwardly uplifting pin which passes through the outer conductor part in the Insulating part engages.

Eine besonders funktionssichere mechanische Verbindung zwischen dem Ring und dem Außenleiterteil erzielt man dadurch, dass der Stift durch eine Durchbrechung im Außenteiterteil greift, welche derart ausgebildet ist, dass eine Drehbewegung des Ringes relativ zum Außenleiterteil blockiert ist.A particularly reliable mechanical connection between the ring and the outer conductor part is achieved in that the pin engages through an opening in the outer side part, which is designed such that a rotational movement of the ring is blocked relative to the outer conductor part.

Eine besonders funktionssichere mechanische Verbindung zwischen dem Ring und dem Innenleiterteil erzielt man dadurch, dass der Stift in eine Ausnehmung im Isolierteil greift, welche derart ausgebildet ist, dass eine Drehbewegung des Isolierteil relativ zum Ring blockiert ist.A particularly reliable mechanical connection between the ring and the inner conductor part is achieved in that the pin engages in a recess in the insulating part, which is designed such that a rotational movement of the insulating part is blocked relative to the ring.

Eine einfache Montage und Demontage der Verdrehsicherung am Gehäuse erzielt man dadurch, dass der Ring aus einem federelastischen Werkstoff ausgebildet ist.A simple assembly and disassembly of the rotation on the housing obtained by the fact that the ring is formed of a resilient material.

Eine zusätzlich axiale Sicherung des Ringes relativ zum Gehäuse erzielt man dadurch, dass an dem Außenumfang des Außenleiterteils eine radial umlaufende Nut ausgebildet ist, in der der Ring angeordnet ist.An additional axial securing of the ring relative to the housing is achieved in that on the outer circumference of the outer conductor part, a radially encircling groove is formed, in which the ring is arranged.

Eine automatische Montage der Verdrehsicherung mit der Montage des Gehäuses erzielt man dadurch, dass die Verdrehsicherung einstückig mit dem Gehäuse ausgebildet ist.An automatic installation of the anti-rotation with the mounting of the housing is achieved in that the anti-rotation is formed integrally with the housing.

Einen Steckverbinder für ein Kabel mit einem oder mehreren Innenleitern erzielt man auf einfache Weise dadurch, dass mindestens ein Innenleiterteil vorgesehen ist, welches zum elektrischen und mechanischen Verbinden mit einem Innenleiter eines Kabels, insbesondere eines HF-Kabels oder eines Stromkabels, ausgebildet ist.A connector for a cable with one or more inner conductors is achieved in a simple manner by providing at least one inner conductor part, which is designed for electrical and mechanical connection to an inner conductor of a cable, in particular an HF cable or a power cable.

Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Diese zeigt in:

The invention will be explained in more detail below with reference to the drawing. This shows in:
Fig. 1
a preferred embodiment of a connector according to the invention in a longitudinal section and
Fig. 2
a preferred embodiment of an anti-rotation in the form of a C-ring in a perspective view.

Die in Fig. 1 dargestellte, bevorzugte Ausführungsform eines erfindungsgemäßen Steckverbinders umfasst ein Gehäuse 10, ein radial innerhalb des Gehäuses 10 angeordnetes Außenleiterteil 12 und ein radial innerhalb des Außenleiterteils angeordnetes Isolierteil 14. Das Gehäuse 10, das Außenleiterteil 12 und das Isolierteil 14 sind koaxial zueinander angeordnet. Der Steckverbinder weist ein steckseitiges Ende 16 zum steckenden Verbinden mit einem komplementären Steckverbinder (nicht dargestellt), und ein kabelseitiges Ende 18 zum elektrischen und mechanischen Verbinden mit einem Kabel (nicht dargestellt) mit einem Außenleiter als elektromagnetische Schirmung und mindestens einem Innenleiter auf. Das Außenleiterteil 12 ist zum elektrischen und mechanischen Verbinden mit dem Außenleiter (nicht dargestellt) des Kabels ausgebildet. Das Isolierteil 14 ist zur Aufnahme von mindestens einem Innenleiterteil (nicht dargestellt) derart ausgebildet, dass das Isolierteil 14 das bzw. die Innenleiterteile an einer vorbestimmten Position innerhalb des Außenleiterteils 12 hält und elektrisch bzgl. des Außenleiterteils 12 isoliert. Das Isolierteil 14 ist beispielsweise aus einem dielektrischen Werkstoff gefertigt, wobei geometrische Abmessungen und dielektrischer Werkstoff derart gewählt sind, dass sich eine vorbestimmte Impedanz des Steckverbinders ergibt. Hierdurch kann der erfindungsgemäße Steckverbinder auch zum Übertragen HF-Signalen verwendet werden.In the Fig. 1 illustrated, preferred embodiment of a connector according to the invention comprises a housing 10, a radially disposed within the housing 10 outer conductor part 12 and a radially disposed within the outer conductor part insulating member 14. The housing 10, the outer conductor part 12 and the insulating member 14 are arranged coaxially to each other. The connector has a male end 16 for mating with a complementary connector (not shown), and a cable end 18 for electrically and mechanically connecting to a cable (not shown) having an outer conductor as the electromagnetic shield and at least one inner conductor. The outer conductor part 12 is designed for electrical and mechanical connection to the outer conductor (not shown) of the cable. The insulating part 14 is configured to receive at least one inner conductor part (not shown) such that the insulating part 14 holds the inner conductor part (s) at a predetermined position within the outer conductor part 12 and isolates it electrically with respect to the outer conductor part 12. The insulating part 14 is for example made of a made of dielectric material, wherein geometric dimensions and dielectric material are selected such that there is a predetermined impedance of the connector. As a result, the connector according to the invention can also be used for transmitting RF signals.

Zwischen dem Gehäuse 10 und dem Außenleiterteil 12 ist eine Verdrehsicherung 20 in Form eines C-Ringes angeordnet, wobei dieser C-Ring 20 im Wesentlichen parallel zu einer Ebene senkrecht zu einer Längsachse des Gehäuses 10 ausgerichtet ist. Die Verdrehsicherung 20 bildet ein Kreissegment aus bzw. ist ein Ring, welcher an einer Stelle unterbrochen ist. Die Verdrehsicherung 20 ist beispielsweise aus einem federelastischen Werkstoff ausgebildet, so dass der C-Ring 20 radial nach innen bzw. außen gebogen werden kann und anschließend selbsttätig unter Wirkung einer federelastischen Kraft in seine Ausgangsstellung zurückkehrt. Dies ermöglicht eine Montage des C-Ringes 20 außen auf dem Außenleiterteil 12 nach dessen Fertigstellung. Hierzu wird der C-Ring 20 beispielsweise radial aufgeweitet und in axialer Richtung über das Außenleiterteil 12 geführt, bis eine vorbestimmte Stelle am Außenumfang des Außenleiterteils 12 erreicht ist, an der beispielsweise eine Nut 22 zur Aufnahme des C-Rings 20 ausgebildet ist. An dieser Stelle wird der C-Ring 20 wieder entlastet, so dass dieser in seine Ausgangstellung in der Nut 22 am Außenumfang des Außenleiterteils 12 zu liegen kommt. Die Verdrehsicherung 20 dient zum drehfesten fixieren des Isolierteils 14 innerhalb des Gehäuses 10 mittels eines sich radial nach innen von der Verdrehsicherung 20 erhebenden Stiftes 24, wie nachfolgend unter Bezugnahme auf Fig. 2 noch näher erläutert wird.Between the housing 10 and the outer conductor part 12 an anti-rotation device 20 is arranged in the form of a C-ring, said C-ring 20 is aligned substantially parallel to a plane perpendicular to a longitudinal axis of the housing 10. The rotation lock 20 forms a circle segment or is a ring which is interrupted at one point. The rotation lock 20 is formed for example of a resilient material, so that the C-ring 20 can be bent radially inwardly or outwardly and then automatically returns under the action of a resilient force in its initial position. This allows mounting of the C-ring 20 on the outside of the outer conductor part 12 after its completion. For this purpose, the C-ring 20, for example, radially expanded and guided in the axial direction over the outer conductor part 12 until a predetermined point on the outer circumference of the outer conductor part 12 is reached, on which, for example, a groove 22 for receiving the C-ring 20 is formed. At this point, the C-ring 20 is relieved again, so that it comes to rest in its initial position in the groove 22 on the outer circumference of the outer conductor part 12. The anti-rotation device 20 is used for rotationally fixed fixing of the insulating part 14 within the housing 10 by means of a radially inwardly of the anti-rotation 20 rising pin 24, as described below with reference to Fig. 2 will be explained in more detail.

Fig. 2 veranschaulicht eine Verdrehsicherung 20 in Form des C-Ringes mit dem Stift 24. Im Bereich des Stiftes 24 weist der C-Ring 20 eine quaderförmige Verdickung 32 auf, welche in eine entsprechende Ausnehmung in einem Innenumfang des Gehäuses 10 greift. Auf diese Weise ist der C-Ring 20 drehfest mit dem Gehäuse 10 mechanisch verbunden. Wie aus Fig. 1 ersichtlich, ist die Ausnehmung in dem Innenumfang des Gehäuses 10 als in axialer Richtung verlaufende Nut 30 ausgebildet, deren Breite in Umfangsrichtung derart gewählt ist, dass die quaderförmige Ausbildung des C-Ringes 20 zwar hinein passt, jedoch eine Drehbewegung des C-Ringes 20 relativ zum Gehäuse 10 durch Anschlagen der quaderförmige Ausbildung des C-Ringes 20 an Innenwandungen der Nut 30 verhindert ist. Fig. 2 illustrates an anti-rotation 20 in the form of the C-ring with the pin 24. In the region of the pin 24, the C-ring 20 has a cuboidal thickening 32, which engages in a corresponding recess in an inner circumference of the housing 10. In this way, the C-ring 20 is rotatably connected to the housing 10 mechanically. How out Fig. 1 can be seen, the recess in the inner circumference of the housing 10 is formed as extending in the axial direction of groove 30 whose width is selected in the circumferential direction such that the cuboidal design of the C-ring 20 fits into it, however, a rotational movement of the C-ring 20 relative to the housing 10 by striking the cuboidal design of the C-ring 20 on inner walls of the groove 30 is prevented.

Wie aus Fig. 1 ersichtlich, greift der Stift 24 durch eine Durchgangsöffnung 26 im Außenleiterteil 12 und in eine Nut 28 im Isolierteil 14, so dass der C-Ring 20 auch drehfest mit dem Isolierteil 14 verbunden ist. Hierdurch ist das Isolierteil 14 drehfest mit dem Gehäuse 10 verbunden, wobei für diese drehfeste Verbindung zwischen Gehäuse 10 und Isolierteil 14 das Außenleiterteil 12 ohne Funktion ist. Mit anderen Worten ist das Außenleiterteil 12 nicht mehr Teil der Toleranzkette für die Verdrehsicherung des Isolierteils 14 in dem Gehäuse 10.How out Fig. 1 can be seen, the pin 24 engages through a through hole 26 in the outer conductor part 12 and into a groove 28 in the insulating member 14 so that the C-ring 20 is also rotatably connected to the insulating member 14. As a result, the insulating member 14 is rotatably connected to the housing 10, wherein the outer conductor part 12 has no function for this rotationally fixed connection between the housing 10 and insulating part 14. In other words, the outer conductor part 12 is no longer part of the tolerance chain for the rotation of the insulating part 14 in the housing 10th

Die Verdrehsicherung 20 stellt eine vorbestimmte Orientierung der in dem Isolierteil 14 gehaltenen Innenleiterteile relativ zum Gehäuse 10 sicher. Hierdurch ist sichergestellt, dass bei einem Einstecken des erfindungsgemäßen Steckverbinders in einen komplementären Steckverbinder das jeweiligen Innenleiterteil des erfindungsgemäßen Steckverbinders mit einem jeweiligen gewünschten Innenleiterteil des komplementären Steckverbinders in elektrischen und mechanischen Kontakt kommt. Mit anderen Worten entspricht die Anordnung der Innenleiterteile in dem erfindungsgemäßen Steckverbinder der Anordnung der Innenleiterteile in dem komplementären Steckverbinder.The rotation lock 20 ensures a predetermined orientation of the inner conductor parts held in the insulating part 14 relative to the housing 10. This ensures that when inserting the connector according to the invention in a complementary connector, the respective inner conductor portion of the connector according to the invention with a respective desired inner conductor portion of the complementary connector comes into electrical and mechanical contact. In other words, the arrangement of the inner conductor parts in the connector according to the invention corresponds to the arrangement of the inner conductor parts in the complementary connector.
