- a feedthrough terminal of the two-part type, from which the present invention is based, is known from the DE 36 13 681 C1 known.
- This lead-through terminal which has been manufactured and sold by the applicant for about 20 years, has a screw terminal body both as outer conductor terminal body and as inner conductor terminal body.
- busbar When mounting the firmly connected to the screw terminal body of a clamp halves busbar is inserted into the open terminal space of the screw terminal body of the other terminal half, so that neither an additional contact nor an additional assembly step is required for electrical connection of the two clamp halves or the two screw connection body.
- the known lead-through terminal has proven to be extremely useful in practice, especially as a high-current lead-through terminal, the connection of the conductors to the two screw terminal bodies is relatively time-consuming due to the connection principle of the screw terminal.

Description
Die Erfindung betrifft eine Durchfiihrungsklemme zur Durchführung einer elektrischen Leitung durch eine Wand, mit einem ersten Klemmengehäuse und einem zweiten Klemmengehäuse, wobei das erste Klemmengehäuse von der einen Seite und das zweite Klemmengehäuse von der anderen Seite her an eine in der Wand ausgebildeten Öffnung heranführbar und miteinander durch die Öffnung, die Wand wischen sich aufnehmend, verbindbar sind, mit mindestens einem im ersten Klemmengehäuse angeordneten ersten Leiteranschlußkörper und mindestens einem im zweiten Klemmengehäuse angeordneten zweiten Leiteranschlußkörper, und mit einer Stromschiene über die der erste Leiteranschlußkörper mit dem zweiten Leiteranschlußkörper elektrisch leitend verbunden ist, wenn das erste Klemmengehäuse und das zweite Klemmengehäuse miteinander verbunden sind.The invention relates to a feed-through terminal for passing an electrical line through a wall, with a first terminal housing and a second terminal housing, wherein the first terminal housing from the one side and the second terminal housing from the other side to an opening formed in the wall and with each other through the opening, the wall wipe receiving, are connectable, with at least one disposed in the first terminal housing first conductor terminal body and at least one arranged in the second terminal housing second conductor terminal body, and electrically connected to a bus bar via which the first conductor terminal body with the second conductor terminal body, when the first terminal housing and the second terminal housing are connected together.
In der industriellen Verbindungstechnik ist es häufig erforderlich, Ströme durch eine Wand, beispielsweise eine Gehäusewand eines industriellen Elektrogeräts, beispielsweise einem Gerät der Leistungselektronik, geführt werden müssen. Hierzu werden Durchführungsklemmen, die teilweise auch als Wand-Durchführungsklemmen bezeichnet werden, eingesetzt, die grundsätzlich bereits seit Jahrzehnten aus der Praxis bekannt sind. Die Durchführungsklemmen sollen einen gleichermaßen zuverlässigen wie bequemen Anschluß der externen Leiter an einen entsprechenden internen Leiter des Elektrogeräts ermöglichen. Die aus der Praxis bekannten Durchführungsklemmen, die ein fingerberührsicheres Isoliergehäuse aufweisen, sind zur Anordnung und Befestigung in Öffnungen und Durchbrüchen von Gehäusewänden derart konzipiert, daß diese in den Öffnungen und Durchbrüchen mit Hilfe verschiedener Techniken montiert werden können.In industrial connection technology, it is frequently necessary to conduct currents through a wall, for example a housing wall of an industrial electrical device, for example a power electronics device. For this purpose lead-through terminals, which are sometimes referred to as wall feed-through terminals used, which are basically known for decades from practice. The feed-through terminals are to allow a reliable as well as convenient connection of the external conductor to a corresponding internal conductor of the electrical device. The known from practice feedthrough terminals, which have a Fingerberührsicheres insulating, are designed for placement and mounting in openings and openings of housing walls in such a way that they can be mounted in the openings and openings by means of various techniques.
Dabei kann grundsätzlich zwischen zwei Typen von Durchführungsklemmen unterschieden werden. Einteilige Durchführungsklemmen, die in eine entsprechend groß bemessene Öffnung in der Wand bis zu einem Anschlag eingeschoben und mittels separater oder am Klemmengehäuse ausgebildeter Rastelemente in der Öffnung fixiert werden, und zweiteilige Durchführungsklemmen, deren beiden Klemmenhälften durch Zusammenstecken miteinander verbunden werden, wobei die beiden Klemmenhälften im miteinander montierten Zustand - zumindest zu ihrem größten Teil - auf unterschiedlichen Seiten der Wand angeordnet sind und die Wand zwischen sich aufnehmen.In principle, a distinction can be made between two types of lead-through terminals. One-piece lead-through terminals, which are inserted into a correspondingly sized opening in the wall up to a stop and fixed by means of separate or formed on the terminal housing locking elements in the opening, and two-part lead-through terminals, the two terminal halves by mating with each other be connected, wherein the two clamp halves in the assembled state - at least for the most part - are arranged on different sides of the wall and receive the wall between them.
Eine Durchführungsklemme des zweiteiligen Typs, von der die vorliegende Erfindung ausgeht, ist aus der
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Durchführungsklemme, der eingangs beschriebenen Art zur Verfügung zu stellen, die bei Beibehaltung der einfachen Montagemöglichkeit einen einfacheren Anschluß der Leiter an die Leiteranschlußkörper ermöglicht.The present invention is therefore an object of the invention to provide a feed-through terminal of the type described above, which allows a simpler connection of the conductor to the conductor terminal body while maintaining the ease of mounting option.
Diese Aufgabe ist bei der eingangs beschriebenen Durchführungsklemme dadurch gelöst, daß sowohl der erste Leiteranschlußkörper als auch der zweite Leiteranschlußkörper jeweils eine Schenkelfeder und ein Metallteil aufweisen, wobei die Schenkelfedern jeweils einen Klemmschenkel und einen Anlageschenkel haben, und wobei der Klemmschenkel und das Metallteil einen Federkraftklemmanschluß für jeweils einen anzuschließenden elektrischen Leiter bilden. Die elektrische Verbindung zwischen den beiden Leiteranschlußkörpern wird dadurch erreicht, daß die Stromschiene in dem ersten Klemmengehäuse angeordnet und mit ihrem einen Ende mit dem Metallteil des ersten Leiteranschlußkörpers elektrisch leitend verbunden ist und das andere Ende der Stromschiene von dem Anlageschenkel des zweiten Leiteranschlußkörpers kontaktiert wird, wenn das erste Klemmengehäuse und das zweite Klemmengehäuse miteinander verbunden sind.This object is achieved with the bushing terminal described above in that both the first conductor terminal body and the second conductor terminal body each have a leg spring and a metal part, wherein the leg springs each have a clamping leg and a plant leg, and wherein the clamping leg and the metal part a spring terminal connection each form an electrical conductor to be connected. The electrical connection between the two conductor terminal bodies is achieved in that the busbar is arranged in the first terminal housing and is electrically connected at its one end to the metal part of the first conductor terminal body and the other end of the busbar of the plant leg of the second conductor terminal body is contacted when the first terminal housing and the second terminal housing are connected together.
Die erfindungsgemäße Durchführungsklemme unterscheidet sich somit zunächst dadurch von der aus dem Stand der Technik bekannten Durchführungsklemme, daß bei den beiden Leiteranschlußkörpern keine Schraubanschlußtechnik, sondern eine Schenkelfederanschlußtechnik realisiert worden ist. Ein anzuschließender, abisolisierter starrer oder mit einer Aderendhülse versehener Leiter kann somit einfach dadurch an die Durchführungsklemme angeschlossen werden, daß der Leiter durch eine im Klemmengehäuse ausgebildete Leitereinführungsöffnung in den Leiteranschlußkörper eingesteckt wird, wobei der anzuschließende Leiter von dem Ende des Klemmschenkels der Schenkelfeder gegen einen Bereich des Metallteils gedrückt und dadurch elektrisch kontaktiert wird. Der starre oder mit einer Aderendhülse bestückte Leiter kann somit ohne Werkzeug direkt an die Durchführungsklemme elektrisch angeschlossen werden; das relativ zeitaufwendige Anziehen der Klemmschraube beim Schraubanschluß entfällt.Thus, the lead-through terminal according to the invention differs first of all from the lead-through terminal known from the prior art in that no screw connection technique, but a leg spring connection technique, has been implemented in the two lead terminal bodies. A to be connected, stripped rigid or provided with a wire end conductor can thus be easily connected to the feedthrough terminal that the conductor is inserted through a formed in the terminal housing conductor insertion opening in the conductor terminal body, the conductor to be connected from the end of the clamping leg of the leg spring against a range pressed the metal part and thereby electrically contacted. The rigid or equipped with a wire end conductor can thus be connected without tools directly to the feed-through terminal electrically; the relatively time-consuming tightening the clamping screw in the screw connection is eliminated.
Bei der aus der
Gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Durchführungsklemme ist das freie Ende des Anlageschenkels der Schenkelfeder des zweiten Leiteranschlußkörpers derart abgebogen, daß es von der Stromschiene wegweist, so daß das freie Ende des Anlageschenkels eine Einführhilfe für das zweite Ende der Stromschiene bildet. Dadurch wird beim Verbinden der beiden Klemmengehäuse das zweite Ende der Stromschiene durch das abgewinkelte Ende des Anlageschenkels leichter in den Federkraftklemmanschluß zwischen dem Anlageschenkel und dem korrespondierenden Bereich des Metallteils eingeführt.According to an advantageous embodiment of the lead-through terminal according to the invention the free end of the abutment leg of the leg spring of the second conductor terminal body is bent so that it points away from the busbar, so that the free end of the abutment leg forms an insertion aid for the second end of the busbar. As a result, when connecting the two terminal housings, the second end of the bus bar is more easily inserted through the angled end of the abutment leg into the spring terminal connection between the abutment leg and the corresponding area of the metal part.
Bezüglich der konkreten Ausgestaltung der Schenkelfedern und der Metallteile der beiden Leiteranschlußkörper gibt es verschiedene Möglichkeiten. Gemäß einer bevorzugten Variante weist das Metallteil zwei einander gegenüberliegende Kontaktwände und einen die Kontaktwände verbindenden Rücken auf, wobei die erste Kontaktwand mit dem Klemmschenkel der Schenkelfeder den Federkraftklemmanschluß für den anzuschließenden Leiter und die zweite Kontaktwand mit dem Anlageschenkel der Schenkelfeder einen Federkraftklemmanschluß für ein Ende der Stromschiene bildet. Ein derartig ausgebildetes Metallteil kann sowohl beim ersten Leiterabschlußkörper als auch beim zweiten Leiteranschlußkörper verwendet werden.With regard to the specific embodiment of the torsion springs and the metal parts of the two conductor connection body, there are various possibilities. According to a preferred variant, the metal part has two opposing contact walls and a back connecting the contact walls, wherein the first contact wall with the clamping leg of the leg spring the Federkraftklemmanschluss for the conductor to be connected and the second contact wall with the plant leg of the leg spring a Federkraftklemmanschluß for one end of the busbar forms. Such a formed metal part can be used both in the first conductor end body and the second conductor terminal body.
Wird ein derartiges Metallteil beim zweiten Leiteranschlußkörper eingesetzt, so bildet die zweite Kontaktwand mit dem Anlageschenkel der Schenkelfeder den Federkraftklemmanschluß für das zweite Ende der Stromschiene, die im ersten Klemmengehäuse angeordnet und mit ihrem ersten Ende mit dem Metallteil des ersten Leiteranschlußkörpers elektrisch leitend verbunden ist. Ist bei einer derartigen Ausgestaltung des zweiten Leiteranschlußkörpers das freie Ende des Anlageschenkels der Schenkelfeder abgebogen, so bildet das freie Ende des Anlageschenkels zusammen mit der zweiten Kontaktwand des Metallteils einen Einführtrichter für das zweite Ende der Stromschiene. Beim Verbinden der beiden Klemmengehäuse wird somit das zweite Ende der Stromschiene von dem Einführtrichter "eingefangen", so daß das Ende der Stromschiene einfach in den Federkraftklemmanschluß zwischen dem Anlageschenkel der Schenkelfeder und der zweiten Kontaktwand eingeschoben werden kann.If such a metal part is used in the second conductor connection body, the second contact wall with the contact leg of the leg spring forms the spring terminal connection for the second end of the conductor rail which is arranged in the first terminal housing and is electrically conductively connected at its first end to the metal part of the first conductor connection body. If the free end of the abutment leg of the leg spring bent in such an embodiment of the second conductor terminal body, the free end of the abutment leg together with the second contact wall of the metal part forms an insertion funnel for the second end of the busbar. When connecting the two terminal housing thus the second end of the busbar is "captured" by the insertion funnel, so that the end of the busbar can be easily inserted into the Federkraftklemmanschluß between the plant leg of the leg spring and the second contact wall.
Wie zuvor bereits ausgeführt worden ist, kann auch das Metallteil des ersten Leiteranschlußkörpers zwei einander gegenüberliegende Kontaktwände und einen die Kontaktwände verbindenden Rücken aufweisen. Gemäß einer anderen, bevorzugten Ausgestaltung ist das Metallteil des ersten Leiteranschlußkörpers jedoch als flacher Strombalken ausgebildet, in dem eine Leiterdurchstecköffnung mit einem sich in Leiterdurchstecköffnung erstreckenden Lochkragen ausgebildet ist. Die Schenkelfeder ist dabei derart angeordnet, daß das Ende des Klemmschenkels der Schenkelfeder in die Leiterdurchstecköffnung eintaucht, so daß der Klemmschenkel der Schenkelfeder mit einer korrespondierenden Innenwand des Lochkragens den Federkraftklemmanschluß für den anzuschließenden Leiter bildet. Ein derartiges Metallteil, das als flacher Strombalken mit einer Leiterdurchstecköffnung und einem Lochkragen ausgebildet ist, kann besonders einfach und materialsparend hergestellt werden. Darüber hinaus kann ein derartiges Metallteil auch sehr geringe Abmessungen aufweisen, so daß insgesamt eine sehr kompakte Durchführungsklemme realisiert werden kann.As has already been stated above, the metal part of the first conductor connection body may also have two mutually opposite contact walls and a back connecting the contact walls. According to another, preferred embodiment, however, the metal part of the first conductor connection body is designed as a flat current bar, in which a Leiterdurchstecköffnung is formed with a hole in Leiterdurchstecköffnung extending hole. The leg spring is arranged such that the end of the clamping leg of the leg spring dips into the Leiterdurchstecköffnung, so that the clamping leg of the leg spring with a corresponding inner wall of the hole collar forms the Federkraftklemmanschluß for the conductor to be connected. Such a metal part, which is designed as a flat current bar with a Leiterdurchstecköffnung and a hole collar can be made particularly simple and save material. In addition, such a metal part can also have very small dimensions, so that a total of a very compact feedthrough terminal can be realized.
Bei einer vorteilhaften Ausgestaltung eines aus einem flachen Strombalken ausgebildeten Metallteils ist die Schenkelfeder dadurch an dem Metallteil befestigt, daß das Ende des Anlageschenkels der Schenkelfeder in die Leiterdurchstecköffnung eingesteckt ist, so daß die Schenkelfeder in der Leiterdurchstecköffnung gehalten ist. Alternativ dazu kann eine weitere Öffnung beabstandet zur Leiterdurchstecköffnung in dem Strombalken ausgebildet sein, in die das Ende des Anlageschenkels der Schenkelfeder eingesteckt und befestigt wird.In an advantageous embodiment of a formed of a flat current bar metal part, the leg spring is thereby fixed to the metal part, that the end of the abutment leg of the leg spring is inserted into the Leiterdurchstecköffnung so that the leg spring is held in the Leiterdurchstecköffnung. Alternatively, a further opening spaced from the Leiterdurchstecköffnung be formed in the current bar, in which the end of the abutment leg of the leg spring is inserted and secured.
Die Fixierung bzw. Halterung der Schenkelfeder in der Leiterdurchstecköffnung kann dadurch weiter verbessert werden, daß der Anlageschenkel der Schenkelfeder seitlich vorspringende Anlageschultern aufweist, die im montierten Zustand der Schenkelfeder und des Metallteils auf dem Rand der Leiterdurchstecköffnung aufliegen. Hierdurch können das Metallteil und die Schenkelfeder einfach vormontiert werden, so daß sie als Baueinheit für die weitere Montage im Klemmengehäuse einfacher eingesetzt werden können. Dabei kann eine zusätzliche Fixierung der Schenkelfeder selbstverständlich durch entsprechend ausgebildete Haltervorsprünge im Klemmengehäuse gewährleistet werden.The fixation or support of the leg spring in the Leiterdurchstecköffnung can be further improved in that the plant leg of the leg spring has laterally projecting abutment shoulders which rest in the mounted state of the leg spring and the metal part on the edge of Leiterdurchstecköffnung. As a result, the metal part and the leg spring can be easily pre-assembled, so that they can be used as a unit for further assembly in the terminal housing easier. In this case, an additional fixation of the leg spring can of course be ensured by appropriately trained holder projections in the terminal housing.
Grundsätzlich kann die Stromschiene sowohl als separates Bauteil ausgebildet als auch einstückig mit dem Metallteil des ersten Leiteranschlußkörpers verbunden sein. Eine einstückige Ausbildung der Stromschiene mit dem Metallteil ist insbesondere dann besonders einfach realisierbar, wenn das Metallteil des ersten Leiteranschlußkörpers als flacher Strombalken ausgebildet ist. Ist die Stromschiene dagegen als separates Bauteil ausgebildet, so wird die Verbindung der Stromschiene mit dem Metallteil des ersten Leiteranschlußkörpers vorzugsweise durch einen Federkraftklemmanschluß zwischen dem ersten Ende der Stromschiene und dem Klemmschenkel oder dem Anlageschenkel der Schenkelfeder realisiert. Eine derartige lösbare Verbindung der Stromschiene mit dem Metallteil des ersten Leiteranschlußkörpers ist dann einfach realisierbar, wenn auch das Metallteil des ersten Leiteranschlußkörpers zwei einander gegenüberliegende Kontaktwände und einen die Kontaktwände verbindenden Rücken aufweist. Dann bildet die zweite Kontaktwand mit dem Anlageschenkel den Federkraftklemmanschluß für das erste Ende der Stromschiene.In principle, the busbar may be formed both as a separate component and integrally connected to the metal part of the first conductor connection body. A one-piece design of the busbar with the metal part is particularly easy to implement in particular when the metal part of the first conductor connection body is formed as a flat current bar. If, however, the busbar is designed as a separate component, then the connection of the busbar to the metal part of the first conductor connection body is preferably realized by a spring terminal connection between the first end of the busbar and the clamping leg or the support leg of the leg spring. Such a releasable connection of the busbar to the metal part of the first conductor connection body is then easily feasible, although the metal part of the first conductor connection body has two mutually opposite contact walls and a connecting walls connecting the backs. Then, the second contact wall with the abutment leg forms the spring terminal connection for the first end of the busbar.
Die mechanische Befestigung zwischen den beiden Klemmengehäusen wird gemäß einer bevorzugten Ausgestaltung dadurch gewährleistet, daß das erste Klemmengehäuse und das zweite Klemmengehäuse einander zugeordnete Rastelemente, insbesondere miteinander in Eingriff bringbare Zahnreihen, aufweisen, so daß das erste Klemmengehäuse und das zweite Klemmengehäuse über die Rastelemente, die Gehäusewand zwischen sich aufnehmend, miteinander verrastbar sind.The mechanical attachment between the two terminal housings is ensured according to a preferred embodiment in that the first terminal housing and the second terminal housing mutually associated locking elements, in particular engageable rows of teeth, have, so that the first terminal housing and the second terminal housing via the locking elements, the Housing wall between them, are latched together.

Im Inneren des ersten Klemmengehäuses 3 ist ein erster Leiteranschlußkörper 5 und im Inneren des zweiten Klemmgehäuses 4 ein zweiter Leiteranschlußkörper 6 angeordnet, wobei der erste Leiteranschlußkörper 5 aufgrund seiner Position außerhalb des Geräts auch als Außenleiteranschlußkörper und der zweite Leiteranschlußkörper 6 aufgrund seiner Position innerhalb des Geräts als Innenleiteranschlußkörper bezeichnet werden kann. Zur elektrischen Verbindung der beiden Leiteranschlußkörpern 5, 6 ist im ersten Klemmengehäuse 3 eine Stromschiene 7 angeordnet und elektrisch leitend mit dem ersten Leiteranschlußkörper 5 verbunden.Inside the first
Wie insbesondere auf
Die zur elektrischen Verbindung der beiden Leiteranschlußkörper 5, 6 vorgesehene Stromschiene 7 ist mit ihrem ersten Ende 18 mit dem Metallteil 9 des ersten Leiteranschlußkörpers 5 dadurch elektrisch leitend verbunden, daß die Stromschiene 7 einstückig mit dem Metallteil 9 ausgebildet ist. Sind die beiden Klemmengehäuse 3, 4 miteinander verrastet, so wird das zweite Ende 19 der Stromschiene 7 vom Anlageschenkel 16 des zweiten Leiteranschlußkörpers 6 kontaktiert, wie dies aus den
Bei dem in den Figuren dargestellten Ausführungsbeispiel einer erfindungsgemäßen Durchführungsklemme 1 weist das Metallteil 14 des zweiten Leiteranschlußkörpers 6 zwei einander gegenüberliegende Kontaktwände 21, 22 auf, die über einen Rücken 23 miteinander verbunden sind. Die Schenkelfeder 13 und das Metallteil 14 sind dabei so zueinander angeordnet, daß der Klemmschenkel 15 mit der ersten Kontaktwand 21 den Federkraftklemmanschluß für den anzuschließenden Leiter 17 und der Anlageschenkel 16 mit der zweiten Kontaktwand 22 einen Federkraftklemmanschluß für das zweite Ende 19 der Stromschiene 7 bilden.In the embodiment of a feedthrough terminal 1 according to the invention shown in the figures, the
Zum Einführen eines mit einer Aderendhülse 24 versehenen Leiters 17 in die Klemmstelle ist im Klemmengehäuse 4 eine Leitereinführungsöffnung 25 ausgebildet. Um das Einführen des elektrischen Leiters 17 in die Klemmstelle zu erleichtern, und um einen angeschlossenen elektrischen Leiter 17 bei Bedarf aus der Klemmstelle wieder zu entfernen, ist in dem Klemmengehäuse 4 eine Betätigungsöffnung 26 zum Einführen eines Betätigungswerkzeugs 27, beispielsweise der Spitze eines Schraubendrehers, ausgebildet. Mit dem Betätigungswerkzeug 27 kann dann auf den Klemmschenkel 15 der Schenkelfeder 8 gedrückt werden, wodurch sich die Schenkelfeder 8 öffnet, so daß ein elektrischer Leiter 17 einfacher eingeschoben oder aus der Klemmstelle herausgezogen werden kann. An dem Klemmschenkel 15 ist ein Knick 28 ausgebildet, der als Angriffspunkt für die Spitze des Betätigungswerkzeugs 27 dient, so daß das ein Entlanggleiten des Betätigungswerkzeugs 27 am Klemmschenkel 15 verhindert wird.For introducing a
Im Unterschied zum Metallteil 14 des zweiten Leiteranschlußkörpers 6 ist das Metallteil 9 des ersten Leiteranschlußkörpers 5 als flacher Strombalken ausgebildet, in dem eine Leiterdurchstecköffnung 29 mit einem sich in Leiterdurchsteckrichtung erstreckenden Lochkragen 30 ausgebildet ist. Das Ende des Klemmschenkels 10 taucht dabei derart in die Leiterdurchstecköffnung 29 ein, daß der Klemmschenkel 10 mit der korrespondierenden Innenwand des Lochkragens 30 den Federkraftklemmanschluß für den anzuschließenden elektrischen Leiter 12 bildet. Ebenso wie das zweite Klemmgehäuse 4, so weist auch das erste Klemmgehäuse 3 eine Leitereinftlhröffnung 31 für den anzuschließenden Leiter 12 und eine Betätigungsöffnung 32 für ein Betätigungswerkzeug 33 auf. Auch hier kann mit Hilfe eines in die Betätigungsöffnung 32 eingeführten Betätigungswerkzeugs 33 der Klemmschenkel 10 der Schenkelfeder 8 ausgelenkt werden, so daß ein elektrischer Leiter 12 einfacher in die Leiterdurchstecköffnung 29 eingesteckt oder ein angeschlossener Leiter 12 aus dem Klemmengehäuse 3 herausgezogen werden kann.In contrast to the
Die Schenkelfeder 8 ist dadurch an dem Metallteil 9 befestigt, daß das Ende des Anlageschenkels 11 ebenfalls in die Leiterdurchstecköffnung 29 eingesteckt ist. Außerdem weist der Anlageschenkel 11 seitlich vorspringende Anlageschultern 34 auf, die im montierten Zustand auf dem Rand der Leiterdurchstecköffnung 29 aufliegen. Zusätzlich ist im Klemmengehäuse 3 ein Haltezapfen 35 zur Positionierung und Halterung der Schenkelfedern 8 und im Klemmengehäuse 4 ausgebildet. Ein entsprechender Haltezapfen 36 ist zur Positionierung und Halterung der Schenkelfedern 13 auch im Klemmengehäuse 4 ausgebildet.The
Die mechanische Verbindung zwischen den beiden Klemmengehäusen 3, 4 erfolgt mit Hilfe einander zugeordneter Rastelemente 37, 38, die bei dem dargestellten bevorzugten Ausführungsbeispiel als miteinander in Eingriff bringbare Zahnreihen ausgeführt sind. Unter Berücksichtigung der Eigenelastizität der aus Kunststoff bestehenden Klemmengehäuse 3, 4 können die Zahnreihe durch einfaches Zusammenschieben der beiden Klemmengehäuse 3, 4 miteinander in Eingriff gebracht werden, so daß eine sichere und dauerhafte Verrastung der beiden Klemmengehäuse 3, 4 gegeben ist. Wie aus
Um eine bestimmte Orientierung der beiden Klemmengehäuse 3, 4 gegenüber der Wand 2 zu gewährleisten, weisen das erste Klemmengehäuse 3 und das zweite Klemmengehäuse 4 einander zugeordnete Drehsicherungselemente 39, 40 auf, wobei bei dem hier dargestellten Ausführungsbeispiel im ersten Klemmengehäuse 3 eine Bohrung und am zweiten Klemmengehäuse 4 ein Stift ausgebildet ist. Bei dem in den Figuren dargestellten Ausführungsbeispiel sind ist die Anschlußrichtung des ersten Leiters 12 im wesentlichen senkrecht zur Anschlußrichtung des zweiten Leiters 17. Selbstverständlich kann die Anschlußrichtung der beiden Leiter 12, 17 auch parallel oder entgegengesetzt zueinander sein, wobei die Anschlußrichtung der beiden Leiter 12, 17 sowohl senkrecht als auch parallel zur Flächennormalen der Wand 2 verlaufen kann.In order to ensure a certain orientation of the two
