Description

Die vorliegende Erfindung betrifft ein mit einer Drahtschutzfeder versehenes elektrisches Kontaktelement, mit einem Gehäuseteil, das ein Sackloch zur Aufnahme der Drahtschutzfeder sowie eine seitliche Gewindebohrung zum Eindrehen einer Klemmschraube aufweist, mit der ein in die Drahtschutzfeder eingeführter elektrischer Leiter festklemmbar ist.The present invention relates to an electrical contact element provided with a wire protection spring, comprising a housing part which has a blind hole for receiving the wire protection spring and a lateral threaded bore for screwing in a clamping screw, with which an electrical conductor inserted into the wire protection spring can be clamped.

Um zu verhindern, dass ein eingeführter elektrischer Leiter beim Festklemmen mittels der Klemmschraube beschädigt wird, kommt eine Drahtschutzfeder zum Einsatz, die den Leiter teilweise umhüllt und an der sich die Klemmschraube abstützt.In order to prevent that an inserted electrical conductor is damaged when clamping by means of the clamping screw, a wire protection spring is used, which partially envelops the conductor and on which the clamping screw is supported.

Ein derartiges Kontaktelement ist aus der EP 1 434 312 A2 bekannt. Die darin gezeigte und beschriebene Drahtschutzfeder ist als U-förmiger Bügel ausgebildet, dessen einer Schenkel mit einem abgewinkelten Ende in ein Loch einer Seitenwand des Gehäuseteiles ragt, wodurch eine axiale Verschiebesicherung der Drahtschutzfeder hergestellt wird.Such a contact element is from the EP 1 434 312 A2 known. The wire protection spring shown therein and described is formed as a U-shaped bracket, one leg of which protrudes with an angled end into a hole of a side wall of the housing part, whereby an axial displacement protection of the wire protection spring is produced.

Allerdings gestaltet sich die Montage der Drahtschutzfeder etwas umständlich. Dies trifft in noch stärkerem Maße auf eine Demontage zu, da der abgewinkelte Endbereich mit einem geeigneten Werkzeug aus dem Loch heraus gedrückt werden muss, um die Drahtschutzfeder herausziehen zu können.However, the mounting of the wire protection spring is somewhat awkward. This applies even more to a disassembly, as the angled End area must be pressed with a suitable tool out of the hole in order to pull out the wire protection spring can.

Im übrigen sind besondere Anforderungen an die Materialeigenschaften dieser Drahtschutzfeder gestellt, da diese beim Einstecken in das Sackloch relativ stark zusammengedrückt werden muss, so dass ausreichend hohe Rückstellkräfte erforderlich sind, um die zusammen gedrückten Schenkel auseinander zu spreizen und das abgewinkelte Ende in dem Loch einrasten zu lassen.Moreover, special requirements are placed on the material properties of this wire guard spring, as they must be compressed relatively strong when plugged into the blind hole, so that sufficiently high restoring forces are required to spread apart the compressed legs apart and engage the angled end in the hole to let.

Alles in allem ist die bekannte Drahtschutzfeder nicht geeignet, eine hinsichtlich der Kosten optimierte Herstellung zu ermöglichen. Dies ist vor allem deshalb problematisch, weil gattungsgemäße Kontaktelemente als Serienteile in großen Stückzahlen hergestellt werden.All in all, the known wire-protection spring is not suitable to allow a production optimized in terms of cost. This is especially problematic because generic contact elements are produced as series parts in large quantities.

Probleme bei der Montage der Drahtschutzfeder ergeben sich auch bei einem gattungsfremden Kontaktelement, das aus der DE 198 04 702 C1 bekannt ist. In dieser Schrift wird vorgeschlagen, die Drahtschutzfeder mittels seitlicher, widerhakenförmiger Anformungen im Gehäuseteil zu verrasten, wobei sich diese Anformungen in das Gehäusematerial eingraben. Hierbei sind naturgemäß Verformungskräfte zu überwinden, die eine einfache und schnelle Montage behindern.Problems with the installation of the wire protection spring also result in a non-generic contact element, which from the DE 198 04 702 C1 is known. In this document, it is proposed to lock the wire protection spring by means of lateral, barb-shaped projections in the housing part, wherein these projections dig into the housing material. This naturally deformation forces are overcome, which hinder a simple and quick installation.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Kontaktelement der gattungsgemäßen Art so weiter zu entwickeln, dass seine Drahtschutzfeder einfach und kostengünstig montier- bzw. demontierbar ist.The present invention is therefore based on the object to develop a contact element of the generic type so that its wire protection spring is easy and inexpensive to assemble or disassemble.

Diese Aufgabe wird durch ein Kontaktelement mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a contact element with the features of claim 1.

Durch diese konstruktive Ausgestaltung ist zum einen eine sehr einfache Montage möglich, da die Drahtschutzfeder ohne großen Kraftaufwand in das Sackloch einsteckbar ist, und zum anderen eine ausreichende Verrastung gewährleistet ist, die einen sicheren Halt der Drahtschutzfeder im Gehäuseteil garantiert.This structural design is on the one hand a very simple installation possible because the wire guard spring can be inserted without much effort into the blind hole, and on the other hand a sufficient locking is guaranteed, which guarantees a secure hold of the wire protection spring in the housing part.

Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, die beiden, sich an die Ausbauchung anschließenden Schenkel, ausgehend von der Ausbauchung, sich im Sinne eines Aufspreizens verlaufen zu lassen, wobei ein kürzerer Schenkel mit einer freien Kante an der Wandung des Sackloches unter Druck an der der Drahtschutzfeder innewohnenden Rückstellkräfte anliegt.According to an advantageous embodiment of the invention, the two, adjoining the bulge thighs, starting from the bulge to let go in the sense of spreading, with a shorter leg with a free edge on the wall of the blind hole under pressure at the the wire protection spring inherent restoring forces.

Als seitliche Ausnehmung des Sackloches, in die die Ausbauchung ragt, kann eine Bohrung vorgesehen sein, die parallel zur Gewindebohrung verläuft, in die eine Klemmschraube eindrehbar ist. Aus fertigungstechnischen Gründen sind die Gewindebohrung und die Bohrung in dieselbe Wandung des Gehäuseteiles eingebracht.As a lateral recess of the blind hole into which the bulge protrudes, a bore may be provided which is parallel to the threaded bore into which a clamping screw can be screwed. For manufacturing reasons, the threaded hole and the bore are introduced into the same wall of the housing part.

Bei Durchführung der Bohrung bis in den gegenüber liegenden Wandungsbereich des Gehäuseteiles bildet die Bohrungsspitze eine weitere seitliche Ausnehmung, in die die Ausbauchung ragt, so dass die Drahtschutzfeder an zwei sich gegenüber liegenden Seiten sowohl axial gesichert wie auch verdrehgesichert einliegt.When carrying out the bore into the opposite wall region of the housing part, the bore tip forms a further lateral recess, in which the bulge protrudes, so that the wire protection spring rests both axially secured on two opposite sides as well as secured against rotation.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

In den Figuren ist ein mit einer bügelförmigen Drahtschutzfeder 4 versehenes elektrisches Kontaktelement dargestellt, das insgesamt mit dem Bezugszeichen 1 versehen ist.In the figures, a provided with a bow-shaped wire protection spring 4 electrical contact element is shown, which is generally designated by the reference numeral 1.

Dieses Kontaktelement 1 weist ein Gehäuseteil 2 auf, an das sich bei dem in den Figuren 1 bis 4 gezeigten Beispiel ein Kontaktstift 3 anschließt, während bei dem in der Figur 5 gezeigten Beispiel statt des Kontaktstiftes 3 eine Kontaktbuchse 13 vorgesehen ist.This contact element 1 has a housing part 2, to which a contact pin 3 is connected in the example shown in FIGS. 1 to 4, while in the example shown in FIG. 5 a contact bush 13 is provided instead of the contact pin 3.

In dem Gehäuseteil 2, sich in axialer Richtung zum Kontaktstift 3 bzw. zur Kontaktbuchse 13 erstreckend, ist ein Sackloch 12 vorgesehen, in dem eine etwa U-förmige Drahtschutzfeder 4 verschiebe- und verdrehgesichert einliegt, die sich am Grund des Sackloches 12 abstützt.In the housing part 2, extending in the axial direction to the contact pin 3 and the contact bushing 13, a blind hole 12 is provided in which an approximately U-shaped wire protection spring 4 displaced and secured against rotation rests, which is supported at the bottom of the blind hole 12.

Die Drahtschutzfeder 4 ist an ihrem der Einführöffnung für einen elektrischen Leiter gegenüber liegenden, dem Grund des Sackloches 12 zugewandten Endbereich als Ausbauchung 5 geformt, an die sich jeweils ein Schenkel 6, 7 anschließt.The wire protection spring 4 is at its the insertion opening for an electrical conductor opposite, the bottom of the blind hole 12 facing end portion formed as a bulge 5, to each of which a leg 6, 7 is connected.

Diese Schenkel 6, 7 sind, ausgehend von der Ausbauchung 5 gespreizt, wobei der Schenkel 7 kürzer ist als der Schenkel 6 und mit einer Kante 8 an der Wandung des Sackloches 12 anliegt. Durch entsprechende Umformung des kürzeren Schenkels 7 ist dieser im Querschnitt der Querschnittskontur des Sackloches 12 angepasst, so dass die Kante 8 über ihre gesamte Länge oder nahezu gesamte Länge unter Reibschluss an der Wandung des Sackloches 12 anliegt.These legs 6, 7 are, starting from the bulge 5 spread, the leg 7 is shorter than the leg 6 and rests with an edge 8 on the wall of the blind hole 12. By appropriate deformation of the shorter leg 7 of this is adapted in cross-section of the cross-sectional contour of the blind hole 12 so that the edge 8 rests against the wall of the blind hole 12 over its entire length or almost entire length with frictional engagement.

Zum Festklemmen eines nicht dargestellten elektrischen Leiters, der von oben in die Sacklochbohrung 12 bzw. die Drahtschutzfeder 4 eingesteckt wird, ist in dem Gehäuseteil 2 eine Gewindebohrung 11 eingebracht, die quer zum Sackloch 12 verläuft und in die eine gleichfalls nicht gezeigte Klemmschraube 11 einschraubbar ist. Diese Klemmschraube stützt sich an dem längeren Schenkel 6 der Drahtschutzfeder 4 ab und drückt diesen gegen die gegenüber liegende Wandung des Sackloches 12 bzw. gegen den kürzeren Schenkel 7.For clamping an electrical conductor, not shown, which is inserted from above into the blind bore 12 and the wire protection spring 4, a threaded bore 11 is introduced into the housing part 2, which extends transversely to the blind hole 12 and into which a clamping screw 11, also not shown, can be screwed , This clamping screw is supported on the longer leg 6 of the wire protection spring 4 and presses against the opposite wall of the blind hole 12 and against the shorter leg. 7

Im unteren Bereich des Sackloches 12 ist eine Bohrung 10 vorgesehen, die parallel zur Gewindebohrung 11 ausgerichtet ist und die eine Ausnehmung bildet, in die die Ausbauchung 5 hinein ragt. Die Bohrung 10 ist bis in den gegenüber liegenden Wandungsbereich des Gehäuseteiles 2 geführt, wobei eine sich ergebende Bohrungsspitze 9 ebenfalls eine solche Ausnehmung bildet, zur Aufnahme eines Teils der Ausbauchung 5.In the lower region of the blind hole 12, a bore 10 is provided, which is aligned parallel to the threaded bore 11 and which forms a recess into which the bulge 5 protrudes. The bore 10 is guided into the opposite wall region of the housing part 2, wherein a resulting bore tip 9 also forms such a recess for receiving part of the bulge 5.

Der durch das Einliegen der Ausbauchung 5 in der Bohrung 10 bzw. der Bohrungsspitze 9 gebildete Formschluss führt zu einer Verschiebe- und Verdrehsicherung der Drahtschutzfeder 4, so dass diese vor einem Einsetzen und Festklemmen des elektrischen Leiters unverlierbar in dem Gehäuseteil 2 gehalten ist.The positive connection formed by the engagement of the bulge 5 in the bore 10 and the bore tip 9 leads to a displacement and anti-rotation of the wire protection spring 4, so that it is held captive in the housing part 2 before inserting and clamping the electrical conductor.
