Abstract
Ein leitfähiges Kontaktstück (10) für eine lösbare elektrische Steckverbindung weist einen Anschlussbereich (11) für einen elektrischen Leiter und einen buchsenförmigen Kontaktbereich (12) zum Aufnehmen eines zylindrischen Kontaktstiftes als Gegenstück der Steckverbindung auf. Der Kontaktbereich (12) weist ein käfigartiges, in Umfangsrichtung (T) um eine Mittelachse (13) tordiertes Buchsenteil (23) mit einer Mehrzahl von untereinander beabstandeten, durch die Torsion radial bezüglich der Mittelachse (13) nach innen gewölbten und elastischen Kontaktlamellen (26) auf. Indem ein Begrenzungselement (37) für einen radial nach außen gerichtete Auslenkung der Kontaktlamellen (26) vorgesehen ist, wird eine sichere Kontaktgabe auch nach einer Vielzahl von wiederholten Steckvorgängen gewährleistet.A conductive contact piece (10) for a detachable electrical plug connection has a connection area (11) for an electrical conductor and a socket-shaped contact area (12) for receiving a cylindrical contact pin as a counterpart of the plug connection. The contact area (12) has a cage-like socket part (23) twisted in the circumferential direction (T) about a central axis (13) with a plurality of spaced apart and elastic contact lamellae (26) that are radially inwardly curved with respect to the central axis (13) by the torsion ) on. By providing a limiting element (37) for a radially outward deflection of the contact lamellae (26), reliable contacting is ensured even after a large number of repeated plugging operations.
Description
Leitfähiges Kontaktstück für eine lösbare elektrische Steckverbindung Die Erfindung betrifft ein leitfähiges Kontaktstück für eine lösbare elektrische Steckverbindung nach dem Oberbegriff des Patentanspruches 1.Conductive contact piece for a detachable electrical The invention relates to a conductive contact piece for a detachable electrical connector according to the preamble of claim 1.
Elektrische Steckverbindungen mit Kontaktstücken der eingangs genannten Art werden z.B. als Rundsteckverbinder zur Leistungsübertragung an Motoren und Antrieben oder aber zur Signalübertragung an Knotenpunkten bei Bussystemen und Steuerungen eingesetzt. Vater- und Mutterteil einer elektrischen Steckverbindung weisen dabei jeweils einen in einem Steckergehäuse lösbar angeordneten Isolierkörper auf, der koaxial zur Steckrichtung ausgerichtete Bohrungen für die Aufnahme leitfähiger Kontaktstücke umfasst. Im Mutterteil der elektrischen Steckverbindung werden die Kontaktstücke durch Kontaktbuchsen gebildet, die bei gesteckter Verbindung als Kontaktstifte ausgebildete Kontaktstücke des Vaterteils zur Herstellung eines elektrischen Kontakts aufnehmen.Electrical plug connections with contact pieces of the type mentioned at the beginning are e.g. as a circular connector for power transmission on motors and drives or for signal transmission at nodes used in bus systems and controls. Father and mother part an electrical connector each have one in a connector housing solvable arranged insulating body on, the holes coaxial to the direction of insertion for receiving conductive contacts includes. In the mother part of the electrical connector, the contacts formed by contact sockets, which when plugged in as Contact pins trained contact pieces of the father part for manufacturing electrical contact.
Aus der deutschen Offenlegungsschrift
Der Erfindung liegt daher die Aufgabe zugrunde, ein Kontaktstück der eingangs genannten Art mit hoher Kontaktsicherheit auch nach einer Vielzahl von erfolgten Steckvorgängen bereitzustellen.The invention is therefore the object based on a contact piece of the type mentioned at the beginning with high contact reliability to provide a variety of mating operations.
Die Aufgabe wird erfindungsgemäß gelöst durch ein gattungsgemäßes Kontaktstück mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1. In dem ein Begrenzungselement für eine radial nach außen gerichtete Auslenkung der Kontaktlamellen vorgesehen ist, ist ein radialer Anschlag für die Kontaktlamellen bereitgestellt. Dieser verhindert ein Auslenken der federelastischen Kontaktlamellen in den plastischen Bereich, so dass die bei der Herstellung des Buchsenteiles eingestellten mechanischen Eigenschaften der Kontaktlamellen nicht durch ein Überdehnen bei unvorsichtigen Steckvorgängen verändert werden können. Es wird somit eine sichere Kontaktierung und damit eine sichere Stromübertragung über sich elastisch an einen eingesteckten Kontaktstift anliegenden Kontaktlamellen gewährleistet.The object is achieved by a generic contact piece with the features of the characterizing part of claim 1. In which a limiting element for one radially outwards Directional deflection of the contact blades is provided radial stop for the contact blades provided. This prevents deflection the resilient contact blades in the plastic area, so that the mechanical set in the manufacture of the socket part Properties of the contact lamellae are not caused by overstretching with careless plug connections changed can be. It is thus a safe contact and thus a safe one Power transmission over itself contact lamellae resiliently against an inserted contact pin guaranteed.
In einer vorteilhaften Ausgestaltung der Erfindung ist das Begrenzungselement ringförmig ausgebildet. Hierdurch wird eine gleichmäßige Begrenzung der radialen Auslenkung aller Kontaktlamellen des Buchsenteiles ermöglicht. Das ringförmige Begrenzungselement ist dabei koaxial zur Mittelachse des Kontaktelementes angeordnet. Vorzugsweise ist der Innendurchmesser des Begrenzungselementes kleiner als der Außendurchmesser des Buchsenteiles.In an advantageous embodiment According to the invention, the limiting element is designed in the shape of a ring. hereby becomes an even limitation the radial deflection of all contact blades of the socket part allows. The ring-shaped Limiting element is coaxial to the central axis of the contact element arranged. The inner diameter of the limiting element is preferably smaller than the outside diameter of the socket part.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Kontaktstückes ist das Begrenzungselement als radiale Ein schnürung eines um das Buchsenteil angeordneten Hülsenteiles ausgebildet. Hierdurch lässt sich in vorteilhafter Weise das Begrenzungselement einfach herstellen und mit einem den empfindlichen Bereich der Kontaktlamellen schützenden und die wenigstens teilweise elastische Torsion des Buchsenteiles arretierenden Hülsenteil kombinieren.In a preferred embodiment of the contact piece according to the invention the limiting element as a radial lacing one around the socket part arranged sleeve part educated. This leaves easily produce the limiting element in an advantageous manner and with one that protects the sensitive area of the contact blades and the at least partially elastic torsion of the socket part Combine the locking sleeve part.
In einer vorteilhaften Ausführungsform der Erfindung ist die Einschnürung des Hülsenteiles im Bereich der Kontaktlamellen bezüglich der Mittelachse mittig angeordnet und axial wesentlich kürzer als der Bereich der Kontaktlamellen ausgebildet. Damit greift das Begrenzungselement an der Stelle der Kontaktlamellen, die bei einem Steckvorgang die größte radiale Auslenkung ausführen. Durch die in Richtung der Mittelachse kurze Ausdehnung des Begrenzungselementes kann das erlaubte radiale Bewegungsspiel der Kontaktlamellen am genauesten eingestellt werden.In an advantageous embodiment the invention is the constriction of the sleeve part centered in the area of the contact lamellae with respect to the central axis arranged and axially much shorter than the area of the contact blades educated. The limiting element thus engages at the location of the contact blades, which perform the greatest radial deflection during a plug-in process. By the short extension of the limiting element in the direction of the central axis the permitted radial movement play of the contact lamellas on be set most precisely.
Weitere Vorteile des erfindungsgemäßen Kontaktstückes ergeben sich aus einem in der Zeichnung dargestellten Ausführungsbeispiel, in deren einziger Figur das Kontaktstück in Seitenansicht mit teilweisem Schnitt schematisch veranschaulicht ist.Further advantages of the contact piece according to the invention result itself from an exemplary embodiment shown in the drawing, in their single figure the contact piece in side view with partial Section is illustrated schematically.
