Abstract

PCT No. PCT/EP96/03574 Sec. 371 Date Apr. 27, 1998 Sec. 102(e) Date Apr. 27, 1998 PCT Filed Aug. 13, 1996 PCT Pub. No. WO97/15963 PCT Pub. Date May 1, 1997A clamp contact device for providing mechanical and electrical attachment for cables, wires, and electrical conductors. A single device can provide simultaneous dual attachment modes for cables, wires, and plugs. One end of the device contains two holes on separate spring legs. The spring legs can be pressed towards each other until the holes are in alignment. By inserting the cable through the aligned holes and releasing the legs, spring tension in the legs tries to force the holes apart, clamping the cable in place. The other end of the device has an opening for insertion of an pin, plug, or similar element. A fork spring that partially extends into the interior of the device provides spring-loaded extensions that contact an inserted plug and hold it in place, without the need to initially press on any part of the device. The device can be manufactured from a single piece of sheet metal. Another embodiment includes a separate spring within the interior of the device, which provides spring tension for the legs, allowing the legs to be made of materials that have good electrical conductivity rather than good spring qualities. This second spring can also serve as a stop to prevent inserted wires from protruding beyond a certain point. This assures that a wire inserted from one end will not interfere with a plug inserted from the other end.

Description

Die Erfindung betrifft eine Klemmkontakteinrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a terminal contact device according to the Preamble of claim 1.

Eine Klemmkontakteinrichtung dieser Art ist aus den Druckschriften EP-A-0 218 133, FR-A-2 524 721 und DE-B-11 96 741 bekannt. Bei allen diesen nach dem gleichen Prinzip aufgebauten und funktionierenden Federklemmen ist eine für die vorgesehenen Zwecke ausreichende Klemmkontaktierung erzielt. Für eine elektrische Verbindung mit einem Steckkontaktelement sind diese Klemmkontakteinrichtungen jedoch weder eingerichtet noch vorgesehen.A terminal contact device of this type is from the publications EP-A-0 218 133, FR-A-2 524 721 and DE-B-11 96 741 known. With all of these built on the same principle and working spring clips is one for the intended Sufficient clamping contact achieved for purposes. For are an electrical connection with a plug contact element these terminal contact devices, however, neither set up nor intended.

Aus der DE 28 00 307 Al ist ein Kontaktstück mit einem auf einer gedruckten Schaltungsplatine aufliegenden und einem schräg dazu verlaufenden beweglichen Federschenkel sowie einer auf der Außenseite des auslenkbaren Federschenkels angeordneten Gabelfeder bekannt. Dieses Kontaktstück ist zwar geeignet zur elektrischen Verbindung mit einem Steckerstift, jedoch nicht zur Klemmkontaktierung eines Kabels. Vor allem aber weist dieses Bauteil durch den in Steckrichtung vorgezogenen, auf der Platine aufliegenden Federschenkel und insbesondere durch die auf der Außenseite des beweglichen Federschenkels vorgesehene Gabelfeder sehr große räumliche Abmessungen auf, die es für sehr viele Anwendungsfälle praktisch unbrauchbar macht.From DE 28 00 307 Al a contact piece with a a printed circuit board and one inclined movable spring legs and one arranged on the outside of the deflectable spring leg Fork spring known. This contact piece is suitable for electrical connection with a connector pin, but not for terminal contacting of a cable. Especially but has this component due to the advanced in the direction of insertion, spring legs resting on the circuit board and in particular through on the outside of the movable spring leg provided fork spring very large spatial dimensions on which it is practical for very many use cases unusable.

Ferner ist aus der DE 42 33 446 C1 eine Klemmkontakteinrichtung bekannt, wie sie schematisch in den Fig. 5 und 6 dargestellt ist, wobei Fig. 5 die Klemmkontakteinrichtung im geschlossenen, also im Klemmzustand, und Fig. 6 die Klemmkontakteinrichtung im offenen Zustand wiedergibt, in dem das Kabel in die Klemmkontakteinrichtung einschiebbar ist. Bei dieser bekannten Klemmkontakteinrichtung befindet sich in einem Kunststoffgehäuse 1 eine Klemmkontaktfeder 2, die mit einem ebenfalls im Kunststoffgehäuse 1 befindlichen Tragekörper 3 vernietet oder verstemmt ist. Die Klemmkontaktfeder 2 weist einen fixierten Federschenkel 4 und einen auslenkbaren Federschenkel 5 auf, wobei letzterer mittels eines Hebels 6 entgegen der Federkraft nach innen zum fixierten Federschenkel 4 hin gedrückt werden kann (vgl. Fig. 6). Durch eine Öffnung 7 im Kunststoffgehäuse 1 kann ein nicht dargestelltes Kabel bzw. die abisolierte Ader eines Kabels in das Kunststoffgehäuse 1 und zwischen den auslenkbaren Federschenkel 5 und einen Anschlag 8 des Tragekörpers 3 geschoben werden. Bei Freigabe des Hebels 6 wird das eingeschobene Kabel bzw. die eingeschobene Kabelader durch die Federkraft des auslenkbaren Federschenkels 5 gegen den Anschlag 8 gedrückt und dadurch der elektrische Kontakt zwischen Kabel und Klemmkontakteinrichtung bzw. Tragekörper 3 geschaffen. Gleichzeitig fixiert der auslenkbare Federschenkel 5 das Kabel bzw. die Kabelader mechanisch, wobei eine freie Kante 9 des auslenkbaren Federschenkels 5 als Kontaktmesser wirkt.Furthermore, from DE 42 33 446 C1 is a terminal contact device known, as shown schematically in FIGS. 5 and 6 5, the terminal contact device in the closed, So in the clamped state, and Fig. 6, the terminal contact device reproduces in the open state in which the cable can be inserted into the terminal contact device. In this known terminal contact device is located in a plastic housing 1, a clamping contact spring 2, the a support body also located in the plastic housing 1 3 riveted or caulked. The clamp contact spring 2 has a fixed spring leg 4 and a deflectable Spring leg 5, the latter by means of a lever 6 against the spring force inwards to the fixed spring leg 4 can be pressed (see FIG. 6). Through an opening 7 in the plastic housing 1 can be a not shown Cable or the stripped wire of a cable in the plastic housing 1 and between the deflectable spring legs 5 and a stop 8 of the support body 3 are pushed. At Release of the lever 6 is the inserted cable or inserted cable core by the spring force of the deflectable Spring leg 5 pressed against the stop 8 and thereby the electrical contact between the cable and the terminal contact device or support body 3 created. Fixed at the same time the deflectable spring leg 5 the cable or the cable core mechanically, with a free edge 9 of the deflectable spring leg 5 acts as a contact knife.

Diese Klemmkontakteinrichtung ist sowohl hinsichtlich der Herstellung als auch der Montage aufwendig. Um eine ausreichende Federwirkung zu erzielen, muß die Kontaktfeder 2 aus Federstahl hergestellt werden, so daß ein zusätzlicher Tragekörper 3 aus Messing oder Bronze erforderlich ist, um eine ausreichende Kontaktierung und einen geringen elektrischen Widerstand zu gewährleisten. Um den Federschenkel 5 auszulenken, d. h. die Klemmkontakteinrichtung zu öffnen bzw. zu schließen, ist ein zusätzlicher Hebel 6 erforderlich. Zum Öffnen der Klemmkontakteinrichtung ist ein Werkzeug, beispielsweise ein Schraubenzieher, erforderlich, der den Bedienungsaufwand des Benutzers erhöht. Darüber hinaus muß die Klemme auf einer Leiterplatte oder einem Gehäuse fest montiert sein, da für die Betätigung der Klemme beide Hände, nämlich eine zum Halten des Kabels, die zweite für das Werkzeug benötigt werden, so daß keine Hand mehr frei ist, um die Klemme selbst festzuhalten. Ein weiterer wesentlicher Nachteil dieser bekannten Klemmkontakteinrichtung besteht darin, daß sie nur mit hohem Aufwand miniaturisierbar ist.This terminal contact device is both in terms of Manufacturing and assembly is complex. To be sufficient To achieve spring action, the contact spring 2 must Spring steel can be made, so that an additional support body 3 of brass or bronze is required to make one sufficient contact and a low electrical To ensure resistance. To deflect the spring leg 5, d. H. to open or close the terminal contact device close, an additional lever 6 is required. To the Opening the terminal contact device is a tool, for example a screwdriver, required, the operating effort of the user increased. In addition, the Terminal firmly mounted on a circuit board or a housing be because both hands are used to operate the clamp, namely one for holding the cable, the second for the tool are needed so that no hand is free to the To hold the clamp yourself. Another major disadvantage this known terminal contact device consists in that it can only be miniaturized with great effort.

Ausgehend von den eingangs aufgeführten bekannten Klemmkontakteinrichtungen gemäß dem Oberbegriff des Patentanspruches 1 liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Klemmkontakteinrichtung zu schaffen, die auf einfache und kostengünstige Weise zusätzlich eine Steckelementkontaktierung ermöglicht und insbesondere als sehr kleine Baueinheit herstellbar ist.Starting from the known terminal contact devices mentioned at the beginning according to the preamble of the claim 1 is the object of the present invention, to create a terminal contact device that is simple and cost-effective way additionally a plug element contact enables and especially as a very small unit can be produced.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing Features of claim 1 solved.

Aufgrund der erfindungsgemäß vorgesehenen Gabelfeder zur Kontaktierung eines Steckerkontaktelements ist die Klemmkontakteinrichtung auf einem sehr viel breiteren Anwendungsgebiet, nämlich auch für den großen Bereich der Kabelsteckverbinder, einsetzbar. Dabei wird die Funktion der Klemmkontaktfeder zum Klemmen und Kontaktieren eines Kabels in keiner Weise beeinträchtigt, weil dieses nur geringfügig über den Klemmbereich der beiden Bohrungen hinaus in den Innenraum zwischen den Federschenkeln einzuführen ist um eine gute Klemmung, Kontaktierung und Auszugssicherung zu gewährleisten. Der gesamte übrige Innenraum zwischen den Federschenkeln kann für die Anordnung der Gabelfeder benutzt werden.Due to the fork spring provided according to the invention for contacting of a plug contact element is the terminal contact device in a much broader field of application, namely for the large area of cable connectors, applicable. The function of the clamping contact spring becomes Clamping and contacting a cable in no way impaired because this is only slightly above the clamping area the two holes into the interior between the spring legs is to introduce a good clamping, contacting and to ensure pull-out protection. The whole remaining interior space between the spring legs can be used for the arrangement the fork spring can be used.

Vor allem aber sind durch die Anordnung der Gabelfeder zwischen den Federschenkeln äußerst geringe Abmessungen der Klemmkontakteinrichtung erreicht, ein Vorteil, der eine Grundforderung bei Steckverbindern erfüllt und die Klemmkontakteinrichtung besonders auch für vielpolige Steckverbinder geeignet macht.But above all, the arrangement of the fork spring between the feather legs extremely small dimensions of the Terminal contact device achieved, an advantage that a Basic requirement for connectors fulfilled and the terminal contact device especially for multipole connectors makes suitable.

Vorteilhafte Ausführungen bzw. Ausgestaltungen der Klemmkontakteinrichtung nach Anspruch 1 sind in den Unteransprüchen angegeben. Advantageous designs or refinements of the terminal contact device according to claim 1 are in the dependent claims specified.

Vorzugsweise stehen die Gabelfederschenkel von den seitlichen Kanten wenigstens eines der Endbereiche der Federschenkel der Klemmkontaktfeder ab und sind in dem Bereich zwischen den Federschenkeln der Klemmkontaktfeder gebogen. An dem Teil des Federkontakts, der den Endbereichen der Federschenkel der Klemmkontaktfeder abgewandt ist, ist gemäß einer weiteren vorteilhaften Ausgestaltung eine Ausnehmung für den Durchgang des Steckerkontaktelements vorgesehen. Auf diese Weise ist es möglich, die Klemmkontakteinrichtung mit wesentlich kleineren Abmessungen als herkömmliche Einrichtungen dieser Art herzustellen, ohne daß Nachteile hinsichtlich der Federwirkung in Kauf genommen werden müssen. Dies wird dadurch erreicht, daß die Anschlußpartie für das abisolierte Kabel und die Gabelfeder bzw. der Gabelkontakt für das Steckerkontaktelement auf engstem Raum ineinander gefaltet sind, so daß sich die Kontaktfederlängen vergrößern und ein ausreichender Federweg erreicht wird, ohne daß dies zu größeren Abmessungen führt.Preferably, the fork spring legs are from the side Edges of at least one of the end regions of the spring legs Clamp contact spring and are in the area between the spring legs the clamp contact spring bent. On the part of the Spring contact, which the end portions of the spring legs of the Clamping contact spring is turned away, is according to another advantageous embodiment, a recess for the passage of the plug contact element provided. That way it is possible, the terminal contact device with much smaller To produce dimensions than conventional devices of this type, without disadvantages in terms of spring action in Purchase must be made. This is achieved in that the connection section for the stripped cable and the fork spring or the fork contact for the plug contact element narrowest space are folded into each other, so that the contact spring lengths increase and sufficient travel is achieved without leading to larger dimensions.

Eine besonders einfache und kostengünstige Fertigung der erfindungsgemäßen Klemmkontakteinrichtung wird vorzugsweise dadurch erreicht, daß die Klemmkontaktfeder mit den Federschenkeln, den Endbereichen, den Schenkeln der Gabelfeder und/oder der Lötöse aus einer Metallplatte oder einem Metallblech vorzugsweise aus Messing oder Bronze einstückig ausgebildet sind. Dadurch ist es möglich, in einem Fertigungsgang sowohl die Bohrungen, als auch das Profil der Federschenkel zum Einschieben in die entsprechenden Ausnehmungen einer Klemmleiste und auch die Ausnehmung für den Durchgang des Steckerkontaktelements in einem Arbeitsgang herzustellen und die Teile der ausgestanzten oder ausgeschnittenen Metallplatte entsprechend in die vorgesehene Lage zu biegen oder zu falten.A particularly simple and inexpensive manufacture of the invention Terminal contact device is preferably thereby achieved that the clamping contact spring with the spring legs, the end regions, the legs of the fork spring and / or the soldering eye made of a metal plate or sheet metal is preferred made of one piece from brass or bronze are. This makes it possible to both in one production run the holes, as well as the profile of the spring legs for insertion in the corresponding recesses of a terminal block and also the recess for the passage of the plug contact element to manufacture and the parts of the punched or cut out metal plate accordingly to bend or fold into the intended position.

Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist eine Zusatzfeder vorgesehen. Diese verbessert die mechanischen Eigenschaften der Klemmkontaktfeder, nämlich deren Kontaktkraft bzw. die Auszugskraft des Kabels oder der kontaktierten Kabelader.According to a particularly advantageous embodiment of the invention an additional spring is provided. This improves the mechanical properties of the terminal contact spring, namely its Contact force or the pull-out force of the cable or contacted wire.

Insbesondere dann, wenn die Klemmkontaktfeder aus Gründen eines guten elektrischen Kontakts aus Messing oder Bronze hergestellt ist, ist die Zusatzfeder von besonderem Vorteil, weil die Federwirkung einer aus diesen Materialien bestehenden Klemmkontaktfeder gegebenenfalls nicht ausreichend ist. Da die Zusatzfeder keine elektrische Kontaktierung schafft, kann sie in vorteilhafter Weise aus Stahl bestehen.Especially when the clamping contact spring for reasons of good electrical contact made of brass or bronze the additional spring is particularly advantageous, because the spring action of one made of these materials Clamp contact spring may not be sufficient. Since the additional spring does not make electrical contact, it can advantageously consist of steel.

Vorzugsweise ist die Zusatzfeder zwischen den Federschenkeln der Klemmkontaktfeder angeordnet, wobei es besonders vorteilhaft ist, wenn sich die Enden des Federblechs oder des Federdrahts an den Federschenkeln der Klemmkontaktfeder abstützen.The additional spring is preferably between the spring legs arranged the clamping contact spring, it being particularly advantageous is when the ends of the spring plate or the spring wire Support on the spring legs of the clamping contact spring.

Die Zusatzfeder zwischen den Federschenkeln der Klemmkontaktfeder ist vorzugsweise so geformt, daß sie die Eindringtiefe des Kabels bzw. der Kabelader in den Kontaktfederbereich begrenzt. Die Zusatzfeder dient also bei dieser Ausführungsform als Anschlag für das eingeführte Kabel, damit dieses nicht in den Steckraum vordringt. Auf diese Weise ist ohne Mehrkosten erreicht, daß die Steckerkontaktelemente, z. B. Messerkontakte eines Gerätesteckverbinders, ohne Behinderung in die Gabelfedern einführbar sind und die Abmessungen der Klemmkontakteinrichtung auch in Steckrichtung gering sind und darüber hinaus für das stets gleich weite Einführen der Kabelenden keine besonderen Vorrichtungen erforderlich sind.The additional spring between the spring legs of the clamping contact spring is preferably shaped to be the depth of penetration of the cable or the cable core limited in the contact spring area. The additional spring thus serves in this embodiment as a stop for the inserted cable, so that it does not come in penetrates the slot. This way there is no additional cost achieved that the plug contact elements, for. B. knife contacts a device connector, without hindrance in the fork springs are insertable and the dimensions of the terminal contact device are also low in the direction of insertion and above also for always inserting the cable ends equally far no special devices are required.

Aus der DE 11 05 937 ist zwar grundsätzlich eine Zusatzfeder gemäß Anspruch 6 bekannt.

Die Federschenkel-Endbereiche 14, 15 weisen Bohrungen 18 bzw. 19 zum Durchführen des Kabels 17 auf.The embodiment shown in FIGS. 1 to 4 one Clamp contact device according to the invention has a clamp contact spring 11 with two spring legs 12, 13 in two Spring leg end portions 14, 15 which end in the manner bent towards the space between the spring legs 12, 13 are that they have at least one core 16 of a cable 17 clamping position to each other in series. The spring leg end areas 14, 15 have holes 18 and 19 for Run the cable 17 on.

    Bei dem dargestellten Ausführungsbeispiel ist die Klemmkontaktfeder 11 in einem Gehäuse 20 aus Kunststoff angeordnet, wobei jedoch eine Seite des Gehäuses 20 frei bleibt, so daß ein Federschenkel 12 der Klemmkontaktfeder 11 mit der Hand bzw. einem Finger erreichbar ist.In the illustrated embodiment, the clamping contact spring 11 arranged in a housing 20 made of plastic, however, one side of the housing 20 remains free, so that a spring leg 12 of the clamping contact spring 11 by hand or a finger can be reached.

    Zwischen den Federschenkeln 12, 13 der Klemmkontaktfeder 11 ist eine Zusatzfeder 21 angeordnet, die aus Federstahl besteht. Diese Zusatzfeder 21 ist im dargestellten Ausführungsbeispiel auf der Innenseite des am Gehäuse 20 anliegenden Federschenkels 13 fixiert, während das freie Ende 22 der Zusatzfeder 21 im oberen Bereich vor dem Biegepunkt 23 des Federschenkels 12 an dessen Innenseite anliegt und dadurch die Federkraft der Klemmkontaktfeder 11 erhöht.Between the spring legs 12, 13 of the clamping contact spring 11 an additional spring 21 is arranged, which consists of spring steel. This additional spring 21 is in the illustrated embodiment on the inside of the spring leg abutting the housing 20 13 fixed while the free end 22 of the additional spring 21 in the upper area before the bending point 23 of the spring leg 12 rests on the inside and thereby the Spring force of the clamp contact spring 11 increased.

    Die Funktionsweise der erfindungsgemäßen Ausführungsform einer Klemmkontakteinrichtung ist folgende:The mode of operation of the embodiment of the invention Terminal contact device is the following:

    In Fig. 1 befindet sich die Kontaktfeder 11 im unbeeinflußten Zustand in einer Lage, in der die Federschenkel 12, 13 zueinander am weitesten beabstandet sind. Soll nun die Kontaktierung eines Kabels 17 bzw. dessen abisolierter Ader 16 erfolgen, wird der sich nicht am Gehäuse 20 abstützende Federschenkel 12 mit dem Finger zum sich am Gehäuse 20 abstützenden Federschenkel 3 entgegen der Federkraft sowohl der Kontaktfeder 11 als auch der Zusatz feder 21 hin gedrückt, bis die beiden Bohrungen 18, 19 der Federschenkel-Endbereiche 14, 15 in Deckung sind. Die Länge des Federschenkel-Endbereichs 14 ist dabei derart gewählt, daß dies bei Anschlag der Federschenkel-Endbereichskante am gegenüberliegenden, sich am Gehäuse 20 abstützenden Federschenkel 13 eintritt. In diesem Zustand, der in Fig. 2 dargestellt ist, ist es nun möglich, die abisolierte Ader 16 des Kabels 17 durch die beiden Bohrungen 18, 19 der Federschenkel-Endbereiche 14, 15 höchstens soweit hindurchzustecken, bis die Ader 16 an der Zusatzfeder 21 anschlägt, wie dies aus Fig. 3 ersichtlich ist. Wird daraufhin nun der Hand- bzw. Fingerdruck auf den sich nicht am Gehäuse 20 abstützenden Federschenkel verringert, versetzen sich die Bohrungen 18, 19 der Federschenkel-Endbereiche 14, 15 zueinander, so daß sie zwischen sich die Ader 16 einklemmen und diese sowohl mechanisch halten als auch die leitende Verbindung zur Klemmkontaktfeder 11 herstellen.In Fig. 1, the contact spring 11 is unaffected State in a position in which the spring legs 12, 13 to each other are the most distant. Now the contacting a cable 17 or its stripped wire 16, will not be supported on the housing 20 spring leg 12 with the finger to be supported on the housing 20 Spring leg 3 against the spring force of both the contact spring 11 and the additional spring 21 pressed until the two bores 18, 19 of the spring leg end regions 14, 15 are in cover. The length of the spring leg end area 14 is chosen such that this is when the spring leg end region edge stops on the opposite, on the housing 20 supporting spring leg 13 occurs. In this State, which is shown in Fig. 2, it is now possible the stripped wire 16 of the cable 17 through the two holes 18, 19 of the spring leg end regions 14, 15 at most push through until the wire 16 on the additional spring 21 strikes, as can be seen from Fig. 3. Thereupon now the hand or finger pressure on the not on Housing 20 supporting spring leg reduced, move bores 18, 19 of spring leg end regions 14, 15 to each other so that they pinch the wire 16 between them and hold it both mechanically and the conductive one Establish connection to clamp contact spring 11.

    In Fig. 4 ist das Ausführungsbeispiel einer Klemmleiste 31 mit drei Gehäusebereichen 32, 33, 34 zur Aufnahme jeweils einer Klemmkontakteinrichtung 35, 36 und 37 schematisch und perspektivisch dargestellt, wobei die Klemmkontakteinrichtungen 35, 36 und 37 außerhalb der Klemmleiste 31, jedoch in der von den Gehäuseteilen 32, 33 und 34 vorgegebenen Lage dargestellt sind.4 is the embodiment of a terminal block 31 with three housing areas 32, 33, 34 for receiving one each Clamp contact device 35, 36 and 37 schematically and shown in perspective, the terminal contact devices 35, 36 and 37 outside the terminal block 31, but in the represented by the housing parts 32, 33 and 34 predetermined position are.

    Bei den dargestellten Ausführungsbeispielen weisen die sich am Gehäuse 20 abstützenden Federschenkel 13 Kantenbereiche 38 bzw. 39 auf, die in entsprechende, komplementäre Nuten 40, 41 der Gehäusebereiche 32, 33 und 34 einschiebbar und darin gehaltert sind. Die Montage ist dadurch denkbar einfach und kostengünstig.In the illustrated exemplary embodiments, they have on the housing 20 supporting spring legs 13 edge regions 38 or 39 on, which in corresponding, complementary grooves 40, 41st the housing areas 32, 33 and 34 can be inserted and held therein are. The assembly is very simple and inexpensive.

    Bei den in Fig. 4 dargestellten Ausführungsformen der Klemmkontakteinrichtung sind weiterhin Lötösen 42 zum Anbringen oder Anlöten eines elektronischen Bauteils, z. B. einer Leuchtdiode oder eines Widerstands vorgesehen.In the embodiments of the terminal contact device shown in FIG. 4 are soldering eyelets 42 to attach or soldering an electronic component, e.g. B. one Light-emitting diode or a resistor is provided.

    Wie am besten aus Fig. 4 ersichtlich ist, stehen an den seitlichen Kanten der Endbereiche 15 des Federschenkels 13 Schenkel 43, 44 ab und bilden innerhalb der Klemmkontaktfeder 11 einen Kontaktbereich für ein nicht dargestelltes Steckerkontaktelement, wie z. B. einen Steckerstift oder ein Steckermesser. Damit das Steckerkontaktelement in die aus den Schenkeln 43, 44 bestehende Gabelfeder einschiebbar ist, ist in dem den Endbereichen abgewandten Ende 45 der Klemmkontaktfeder 11 eine Ausnehmung 46 vorgesehen, durch die das Steckerkontaktelement zwischen die Gabelfeder 43, 44 gesteckt und kontaktiert wird. As best seen in Fig. 4, are on the side Edges of the end regions 15 of the spring leg 13 leg 43, 44 and form within the clamping contact spring 11 a contact area for a plug contact element, not shown, such as B. a connector pin or a connector knife.

    Durch diese Ineinanderfaltung des Kontaktbereichs für das Steckerkontaktelement in die Klemmkontaktfeder 11 ergibt sich eine sehr kompakte, nur einen geringen Raumbedarf benötigende Einrichtung, ohne daß Abstriche an der Federwirkung gemacht werden müssen, weil die Federwege dennoch ausreichend groß bleiben.Through this folding of the contact area for the Plug contact element in the clamping contact spring 11 results a very compact, taking up little space Setup without sacrificing spring action have to be because the spring travel is still large enough stay.

    Die Erfindung wurde anhand eines bevorzugten Auführungsbeispiels erläutert. Dem Fachmann sind jedoch zahlreiche Abwandlungen und Ausgestaltungen möglich, ohne daß dadurch der durch die Ansprüche definierte Bereich verlassen wird. Beispielsweise ist es möglich, eine Hebelelement vorzusehen, mit dem auf einen oder auf beide Federschenkel 12, 13 Druck ausgeübt werden kann. Weiterhin ist es möglich, auf beide Federschenkel 12, 13 zur relativen Versetzung der Bohrungen 18, 19 zueinander Druck auszuüben, in dem das Gehäuse 20 entsprechend ausgebildet ist.The invention was based on a preferred exemplary embodiment explained. However, numerous modifications are known to the person skilled in the art and configurations possible without thereby reducing the scope defined by the claims is left. For example, it is possible to provide a lever element with which on one or pressure can be exerted on both spring legs 12, 13. Furthermore, it is possible to on both spring legs 12, 13 relative displacement of the bores 18, 19 to each other pressure exercise in which the housing 20 is formed accordingly is.
