Im Ergebnis können hierdurch die maximal zulässigen Leiter-Auszugskräfte der Leiteranschlussklemme erhöht werden.This has the advantage that the actuating lever is integrated into the stiffening and stabilization of the mechanical structure of the conductor terminal, in particular the insulating housing, and thus has an additional function in addition to the function of actuating the clamping spring, namely increasing the mechanical stability of the conductor terminal. If a tensile force is applied to the cover part, for example by pulling from the outside on the electrical conductor clamped to the contact insert, then in the present invention the cover part can move in addition to other fixing elements, such as the form-fitting fixation by means of the form-fitting element, on the further fixation provided by the retaining edge of the actuating lever and thereby transmit the forces to other parts of the insulating material housing. In this way, a loosening or pulling out of the cover part from the main housing part can be effectively counteracted. As a result, the maximum permissible conductor pull-out forces of the conductor connection terminal can be increased.

Das wenigstens eine Formschlusselement dient zur Fixierung des Deckelteils am Hauptgehäuseteil. Ein solches Formschlusselement kann beispielsweise als Rastelement ausgebildet sein, sodass das Deckelteil mittels Verrastung durch dieses Formschlusselement beziehungsweise Rastelement am Gehäuseteil fixiert werden kann. Das wenigstens eine Formschlusselement kann integraler Bestandteil des Deckelteils sein, z.B. indem das wenigstens eine Formschlusselement einstückig mit dem Deckelteil ausgeformt ist. Das Deckelteil kann beispielsweise eine entsprechende Gegenkontur aufweisen, die mit der Haltekante zum Sichern des Deckelteils am Hauptgehäuseteil zusammen wirkt.The at least one positive-locking element is used to fix the cover part to the main housing part. Such a form-fitting element can be designed, for example, as a latching element, so that the cover part can be fixed to the housing part by means of latching by this form-fitting element or latching element. The at least one form-fitting element can be an integral part of the cover part, e.g. by the at least one form-fitting element being formed in one piece with the cover part. The cover part can have a corresponding counter-contour, for example, which interacts with the holding edge to secure the cover part on the main housing part.

Der Kontakteinsatz weist zumindest wenigstens eine Klemmfeder auf. Die Klemmfeder kann einen Anlageschenkel, einen sich an den Anlageschenkel anschließenden Federbogen und einen sich an den Federbogen anschließenden Klemmschenkel aufweisen. Der Klemmschenkel kann an seinem freien Ende mit einer Klemmkante enden, die zum Festklemmen des elektrischen Leiters dient. Der Anlageschenkel dient zur mechanischen Befestigung und Abstützung der Klemmfeder an wenigstens einem Teil der Leiteranschlussklemme, z.B. am Betätigungshebel, an einer Stromschiene und/oder an dem Isolierstoffgehäuse. Der Kontakteinsatz kann zusätzlich beispielsweise eine Stromschiene aufweisen, die mit der Klemmfeder gekoppelt ist. Die Stromschiene kann einen Leiterauflagebereich haben, an dem der anzuklemmende elektrische Leiter mittels der Klemmfeder gegen die Stromschiene gedrückt wird. Die Klemmstelle wird dann zwischen der Klemmkante des Klemmschenkels und dem Leiteranlagebereich der Stromschiene gebildet.The contact insert has at least one clamping spring. The clamping spring can have a contact leg, a spring bow adjoining the contact leg and a clamping leg adjoining the spring bow. The clamping leg can have a clamping edge at its free end ends, which is used to clamp the electrical conductor. The contact leg serves to mechanically fasten and support the clamping spring on at least one part of the conductor connection terminal, for example on the actuating lever, on a conductor rail and/or on the insulating housing. The contact insert can additionally have a busbar, for example, which is coupled to the clamping spring. The busbar can have a conductor support area on which the electrical conductor to be clamped is pressed against the busbar by means of the clamping spring. The clamping point is then formed between the clamping edge of the clamping leg and the conductor contact area of the busbar.

Wie erwähnt, weist der Betätigungshebel zumindest eine geöffnete und eine geschlossene Stellung auf. Hierbei kann die geöffnete Stellung des Betätigungshebels mit einer geöffneten Klemmstelle korrespondieren, die geschlossene Stellung des Betätigungshebels kann mit einer geschlossenen Klemmstelle korrespondieren. Bei geschlossener Klemmstelle wird ein elektrischer Leiter mittels der Klemmfeder festgeklemmt, bei geöffneter Klemmstelle kann der elektrische Leiter im Wesentlichen ohne Kraftaufwand aus der Klemmstelle entfernt werden oder in die Klemmstelle eingeführt werden.As mentioned, the actuating lever has at least one open and one closed position. The open position of the actuating lever can correspond to an open clamping point, and the closed position of the actuating lever can correspond to a closed clamping point. When the terminal point is closed, an electrical conductor is clamped by means of the clamping spring; when the terminal point is open, the electrical conductor can be removed from the terminal point or inserted into the terminal point essentially without any effort.

Das Hauptgehäuseteil kann beispielsweise eine Aussparung oder Öffnung aufweisen, die dazu genutzt werden kann, den Kontakteinsatz im Hauptgehäuseteil anzuordnen. Um diese Aussparung oder Öffnung zumindest weitgehend zu verschließen, dient das Deckelteil, das beispielsweise ganz oder teilweise in die Aussparung oder Öffnung eingesetzt werden kann und darin fixiert werden kann. Um den anzuklemmenden elektrischen Leiter in das Isolierstoffgehäuse einführen zu können, weist das Isolierstoffgehäuse eine Leitereinführungsöffnung auf. Die Leitereinführungsöffnung kann am Hauptgehäuseteil oder am Deckelteil angeordnet sein. Das Deckelteil kann beispielsweise einen sich an die Leitereinführungsöffnung anschließenden Leitereinführungskanal aufweisen, durch den ein elektrischer Leiter gezielt zur Klemmstelle geführt werden kann.The main housing part can, for example, have a recess or opening which can be used to arrange the contact insert in the main housing part. The cover part, which can be inserted completely or partially into the recess or opening and can be fixed therein, is used to at least largely close this recess or opening. In order to be able to insert the electrical conductor to be connected into the insulating material housing, the insulating material housing has a conductor insertion opening. The conductor insertion opening can be arranged on the main housing part or on the cover part. The cover part can, for example, have a conductor insertion channel which is connected to the conductor insertion opening and through which an electrical conductor can be guided in a targeted manner to the clamping point.

Gemäß der Erfindung ist vorgesehen, dass das Deckelteil zumindest bei geschlossenem Betätigungshebel mittels der wenigstens einen Haltekante gegen ein Lösen von dem Hauptgehäuseteil dadurch gesichert ist, dass das wenigstens eine Formschlusselement des Deckelteils von der wenigstens einen Haltekante umgriffen ist. Auf diese Weise wird das Formschlusselement, das bereits zur Fixierung des Deckelteils am Hauptgehäuseteil dient, zusätzlich für die Fixierung zwischen dem Betätigungshebel und dem Deckelteil genutzt. Dementsprechend kann in dieser Ausführungsform die erwähnte Gegenkontur des Deckelteils durch das wenigstens eine Formschlusselement realisiert werden, zum Beispiel durch eine als Gegenstück zur Haltekante wirkende Fixierkante des Formschlusselements.According to the invention it is provided that the cover part at least when the actuating lever is closed by means of the at least one retaining edge against loosening the main housing part is secured in that the at least one form-fitting element of the cover part is encompassed by the at least one holding edge. In this way, the form-fitting element, which is already used to fix the cover part on the main housing part, is also used for the fixation between the actuating lever and the cover part. Accordingly, in this embodiment, the aforementioned counter-contour of the cover part can be realized by the at least one form-fitting element, for example by a fixing edge of the form-fitting element acting as a counterpart to the holding edge.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass ein elektrischer Leiter am Kontakteinsatz mittels der Klemmfeder durch Federkraft fixierbar ist, wobei eine auf den elektrischen Leiter außerhalb der Leiteranschlussklemme ausgeübte Zugkraft auf den Kontakteinsatz und hiervon auf das Deckelteil und vom Deckelteil auf den Betätigungshebel übertragbar ist. Durch die auf diese Weise gebildete Kraftkette kann die auf den elektrischen Leiter ausgeübte Zugkraft wirkungsvoll auf den Betätigungshebel übertragen werden und damit zumindest teilweise vom Deckelteil abgeleitet werden.According to an advantageous embodiment of the invention, it is provided that an electrical conductor can be fixed to the contact insert by means of the clamping spring by spring force, with a tensile force exerted on the electrical conductor outside the conductor connection terminal being transferrable to the contact insert and from there to the cover part and from the cover part to the actuating lever . The force chain formed in this way allows the tensile force exerted on the electrical conductor to be effectively transmitted to the actuating lever and thus at least partially derived from the cover part.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die auf den elektrischen Leiter außerhalb der Leiteranschlussklemme ausgeübte Zugkraft vom Betätigungshebel auf das Hauptgehäuseteil übertragbar ist. Auf diese Weise kann die erwähnte Kraftkette fortgesetzt werden bis zum Hauptgehäuseteil, das heißt zu einer Stelle, an der der Betätigungshebel wiederum am Hauptgehäuseteil befestigt und/oder gelagert ist.According to an advantageous embodiment of the invention, it is provided that the tensile force exerted on the electrical conductor outside of the conductor connection terminal can be transferred from the actuating lever to the main housing part. In this way, the chain of forces mentioned can be continued up to the main housing part, ie to a point at which the operating lever is in turn fastened and/or supported on the main housing part.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Betätigungshebel einen Federbetätigungsbereich, an dem wenigstens ein Federbetätigungselement zur Auslenkung der Klemmfeder angeordnet ist, und einen manuellen Griffbereich aufweist, an dem der Betätigungshebel manuell zu betätigen ist, wobei die Haltekante in dem manuellen Griffbereich angeordnet ist. Auf diese Weise kann die Haltekante an einer geeigneten Stelle am Betätigungshebel angeordnet werden, ohne dass die den Betätigungsmechanismus der Klemmfeder betreffenden Bereiche des Betätigungshebels davon betroffen sind oder ggf. umgestaltet werden müssen.According to an advantageous embodiment of the invention, it is provided that the actuating lever has a spring actuating area on which at least one spring actuating element for deflecting the clamping spring is arranged, and a manual gripping area on which the actuating lever can be actuated manually, with the holding edge being arranged in the manual gripping area is. In this way, the holding edge can be arranged at a suitable point on the actuating lever without the areas of the actuating lever affecting the actuating mechanism of the clamping spring being affected or possibly having to be redesigned.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Betätigungshebel an seiner zum Deckelteil weisenden Seite wenigstens eine Ausnehmung aufweist, an der die Haltekante angeordnet ist. Auf diese Weise kann die Ausnehmung mit der Haltekante sozusagen an der Innenseite des Betätigungshebels und insbesondere an der Innenseite des manuellen Betätigungsbereichs angeordnet werden. Auf diese Weise kann die Fixierung des Deckelteils mittels des Betätigungshebels besonders effizient gestaltet werden. Zudem ist diese Fixierung nicht störend für die manuelle Betätigung des Betätigungshebels und das optische Erscheinungsbild der Leiteranschlussklemme. Die Ausnehmung kann insbesondere nach Art eines Sacklochs ausgebildet sein, das heißt als Ausnehmung, die den Betätigungshebel beziehungsweise den manuellen Betätigungsbereich nicht vollständig durchdringt.According to an advantageous embodiment of the invention, it is provided that the actuating lever has at least one recess on its side facing the cover part, on which the holding edge is arranged. In this way, the recess with the retaining edge can be arranged, so to speak, on the inside of the operating lever and in particular on the inside of the manual operating area. In this way, the fixing of the cover part by means of the actuating lever can be configured particularly efficiently. In addition, this fixation does not interfere with the manual operation of the operating lever and the visual appearance of the conductor terminal. The recess can in particular be designed in the manner of a blind hole, that is to say as a recess which does not completely penetrate the operating lever or the manual operating area.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass ein aus dem Hauptgehäuseteil herausragender Bereich des Formschlusselements des Deckelteils im geschlossenen Zustand des Betätigungshebels in die Ausnehmung hineinragt. Auf diese Weise kann eine formschlüssige Fixierung zwischen der in der Ausnehmung angeordneten Haltekante und dem Formschlusselement des Deckelteils auf einfache Weise realisiert werden.According to an advantageous embodiment of the invention, it is provided that a region of the form-fitting element of the cover part protruding from the main housing part protrudes into the recess when the actuating lever is in the closed state. In this way, a form-fitting fixation between the holding edge arranged in the recess and the form-fitting element of the cover part can be realized in a simple manner.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Betätigungshebel zumindest in der geschlossenen Stellung am Hauptgehäuseteil rastend fixierbar ist. Hierdurch kann sichergestellt werden, dass der Betätigungshebel in definierter Weise in der geschlossenen Stellung verharrt, auch wenn die Leiteranschlussklemme beispielsweise durch Vibration oder ähnliche äußere Einflüsse belastet wird. Die rastende Fixierung des Betätigungshebels am Hauptgehäuseteil kann beispielsweise dadurch realisiert werden, dass das Hauptgehäuseteil wenigstens ein Gehäuserastelement aufweist, das zum Zusammenwirken mit wenigstens einem am Betätigungshebel angeordneten Hebelrastelement ausgebildet ist. Hierdurch kann der Betätigungshebel zumindest in der geschlossenen Stellung durch Zusammenwirken des Hebelrastelements mit dem Gehäuserastelement rastend fixiert werden. Ferner kann durch das Zusammenwirken des Hebelrastelements mit dem Gehäuserastelement auf einfache Art und Weise eine Übertragung der auf den elektrischen Leiter außerhalb der der Leiteranschlussklemme ausgeübten Zugkraft von dem Betätigungshebel auf das Hauptgehäuseteil sichergestellt werden.According to an advantageous embodiment of the invention, it is provided that the actuating lever can be fixed in a latching manner on the main housing part, at least in the closed position. In this way it can be ensured that the actuating lever remains in the closed position in a defined manner, even if the conductor connection terminal is stressed, for example by vibration or similar external influences. The latching fixation of the actuating lever on the main housing part can be realized, for example, in that the main housing part has at least one housing latching element which is designed to interact with at least one lever latching element arranged on the actuating lever. As a result, the actuating lever can be fixed in a latching manner, at least in the closed position, by the interaction of the lever latching element with the housing latching element. Furthermore, through the interaction of the lever latching element with the housing latching element, transmission of the tensile force exerted on the electrical conductor outside of the conductor terminal can be ensured in a simple manner from the actuating lever to the main housing part.

Das Hebelrastelement kann zum Beispiel als einer oder zwei an gegenüberliegenden Seiten seitlich vom manuellen Betätigungsbereich abragende Rastzapfen ausgebildet sein. Das Gehäuserastelement kann als dem jeweiligen Hebelrastelement zugeordnete Rastaussparung in einer Seitenwand des Hauptgehäuseteils ausgebildet sein. Die Rastzapfen können dann in die Rastaussparungen des Hauptgehäuseteils eingreifen.The lever locking element can be designed, for example, as one or two locking pins projecting laterally from the manual actuation area on opposite sides. The housing latching element can be designed as a latching recess in a side wall of the main housing part, which is assigned to the respective lever latching element. The locking pins can then engage in the locking recesses of the main housing part.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Hauptgehäuseteil eine federnde Rastzunge aufweist, die bei am Hauptgehäuseteil befestigtem Deckelteil das Formschlusselement des Deckelteils untergreift und mit einer Rastkante hintergreift. Dies ermöglicht eine zuverlässige Fixierung des Deckelteils am Hauptgehäuseteil. So kann beispielsweise das Hauptgehäuseteil auf der dem Betätigungshebel zugewandten Seite eine parallel zur Leitereinsteckrichtung vorstehende Rastzunge mit einem endseitigen Rasthaken aufweisen. In diesem Fall kann das Formschlusselement des Deckelteils beispielsweise als bügelförmige Haltelasche ausgebildet sein, die durch die Rastzunge mit dessen endseitigem Rasthaken rastend unter- und hintergriffen wird. Die Rastkante ist somit am endseitigen Rasthaken ausgebildet.According to an advantageous embodiment of the invention, it is provided that the main housing part has a resilient latching tongue which, when the cover part is fastened to the main housing part, engages under the form-fitting element of the cover part and engages behind it with a latching edge. This enables the cover part to be reliably fixed to the main housing part. For example, the main housing part can have, on the side facing the actuating lever, a latching tongue that projects parallel to the conductor insertion direction and has a latching hook at the end. In this case, the positive-locking element of the cover part can be designed, for example, as a bow-shaped holding tab, which is latched under and behind by the latching tongue with its end-side latching hook. The latching edge is thus formed on the latching hook at the end.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Deckelteil an der dem Formschlusselement abgewandten Seite ein weiteres Formschlusselement aufweist, dass zur formschlüssigen Verbindung mit einem Haltelement des Hauptgehäuseteils eingerichtet ist. Auf diese Weise kann das Deckelteil an zumindest zwei voneinander beabstandeten Stellen formschlüssig mit dem Hauptgehäuseteil verbunden werden.According to an advantageous embodiment of the invention, it is provided that the cover part has a further form-fitting element on the side facing away from the form-fitting element, which is set up for a form-fitting connection with a holding element of the main housing part. In this way, the cover part can be positively connected to the main housing part at at least two locations spaced apart from one another.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Hauptgehäuseteil eine Oberseite, an der der Betätigungshebel zumindest in der geöffneten Stellung aus dem Hauptgehäuseteil herausragt, und eine der Oberseite gegenüberliegende Unterseite aufweist, wobei das Hauptgehäuseteil mehrere die Oberseite mit der Unterseite verbindende Vertikalwände aufweist, wobei an wenigstens einer Vertikalwand ein Seitenfixierelement angeordnet ist, durch das das Deckelteil seitlich durch Formschluss an dem Hauptgehäuseteil fixierbar ist. Hierdurch wird eine zusätzliche formschlüssige Fixierung zwischen dem Hauptgehäuseteil und dem Deckelteil realisiert. Dies ermöglicht es beispielsweise, die Vertikalwände zusätzlich zu stabilisieren und gegenüber einem Herausbiegen oder Wegbiegen zusichern.According to an advantageous embodiment of the invention, it is provided that the main housing part has an upper side, on which the actuating lever projects out of the main housing part at least in the open position, and an underside opposite the upper side, the main housing part having a plurality of vertical walls connecting the upper side with the underside, a lateral fixing element being arranged on at least one vertical wall, by means of which the cover part can be fixed laterally to the main housing part by positive locking. Through this an additional form-fitting fixation between the main housing part and the cover part is realized. This makes it possible, for example, to additionally stabilize the vertical walls and secure them against bending out or bending away.

Hierzu kann am Deckelteil ein dem Seitenfixierelement zugeordnetes Seitenformschlusselement angeordnet sein, mit dem bei am Hauptgehäuseteil befestigtem Deckelteil die formschlüssige Verbindung zum Seitenfixierelement hergestellt wird. Die formschlüssige Verbindung kann beispielsweise als Rastverbindung ausgebildet sein, in diesem Fall kann das Seitenfixierelement als Rastelement ausgebildet sein, zum Beispiel mit einer parallel zur Leitereinsteckrichtung ausgerichteten Rastzunge mit einem endseitigen Rasthaken. Weitere Realisierungsmöglichkeiten für das Seitenfixierelement ist die Ausbildung als Rastzapfen und/oder mit einer Schwalbenschwanz-Geometrie.For this purpose, a side form-fitting element assigned to the side fixing element can be arranged on the cover part, with which the form-fitting connection to the side fixing element is produced when the cover part is fastened to the main housing part. The form-fitting connection can be designed as a snap-in connection, for example, in which case the lateral fixing element can be designed as a snap-in element, for example with a snap-in tongue oriented parallel to the conductor insertion direction with a snap-in hook at the end. Further realization possibilities for the lateral fixing element is the design as a latching pin and/or with a dovetail geometry.

Die Vertikalwände können insbesondere als Seitenwände des Hauptgehäuseteils ausgebildet sein, das heißt als seitliche Wände, die das Hauptgehäuseteil nach außen hin begrenzen. Ist die Leiteranschlussklemme als mehrpolige Leiteranschlussklemme ausgebildet, die mehrere voneinander getrennte Leiteranschlusskammern aufweist, so können durch das Isolierstoffgehäuse außer den Seitenwänden auch innenliegende Zwischenwände gebildet sein, durch die weitere Vertikalwände realisiert werden. Auch an solchen Zwischenwänden können die erwähnten Seitenfixierelemente realisiert sein.The vertical walls can in particular be designed as side walls of the main housing part, that is to say as side walls which delimit the main housing part on the outside. If the conductor connection terminal is designed as a multi-pole conductor connection terminal which has a plurality of separate conductor connection chambers, the insulating material housing can also form internal partition walls in addition to the side walls, through which further vertical walls can be realized. The side fixing elements mentioned can also be realized on such partition walls.

Die zuvor erläuterte Ausgestaltung der erfindungsgemäßen Leiteranschlussklemme ist zudem als eigenständige Erfindung anzusehen. Die Erfindung betrifft daher auch eine Leiteranschlussklemme, die folgendes aufweist: das Deckelteil die wenigstens eine Leitereinführungsöffnung aufweist.The configuration of the conductor connection terminal according to the invention explained above is also to be regarded as an independent invention. The invention therefore also relates to a conductor connection terminal which has the following: the cover part has the at least one conductor insertion opening.

Im Sinne der vorliegenden Erfindung ist unter dem unbestimmten Begriff "ein" kein Zahlwort zu verstehen. Wenn also z.B. von einem Bauteil die Rede ist, so ist dies im Sinne von "mindestens einem Bauteil" zu interpretieren. Soweit Winkelangaben in Grad gemacht werden, beziehen sich diese auf ein Kreismaß von 360 Grad (360°). Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Verwendung von Zeichnungen näher erläutert.For the purposes of the present invention, the indefinite term "a" is not to be understood as a numeral. If, for example, a component is mentioned, this should be interpreted in the sense of "at least one component". If angles are specified in degrees, these refer to a circular measurement of 360 degrees (360°). The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

Die Figur 1 zeigt zunächst die hauptsächlichen Komponenten der Leiteranschlussklemme 1. Die Leiteranschlussklemme 1 ist im dargestellten Ausführungsbeispiel als zweipoliger Steckverbinder ausgebildet. Hierzu weist die Leiteranschlussklemme 1 einen Steckverbinderbereich 6 und einen Leiteranschlussbereich 7 auf. Die Leiteranschlussklemme 1 weist ein Isolierstoffgehäuse 2 auf, dass sich über den Steckverbinderbereich 6 und den Leiteranschlussbereich 7 erstreckt. Die Leiteranschlussklemme 1 weist zudem für jeden der zwei im Isolierstoffgehäuse 2 angeordneten Kontakteinsätze (wie nachfolgend noch erläutert) jeweils einen Betätigungshebel 5 auf. Der Betätigungshebel 5 ist im oberen Bereich der Figur 1 in der geschlossenen Stellung wiedergegeben, im unteren Bereich in der geöffneten Stellung. In der Figur 1 sind zudem zwei Schnittlinien A-A und B-B eingezeichnet, anhand derer unter Verwendung der Figuren 2 und 3 der innere Aufbau der Leiteranschlussklemme 1 erläutert werden soll. Die Leiteranschlussklemme 1 ist in beiden Bereichen, das heißt im Bereich der Schnittlinie B-B und der Schnittlinie A-A gleich aufgebaut, sodass die Ausführungen für beide Bereiche gelten. Es ist zu beachten, dass die Schnittlinie A-A etwa in der Mitte des Leiteranschlussbereichs 7 einen vertikalen Versatz aufweist, sodass die Schnittlinie A-A nicht eine durchgehende Schnittebene widergibt.the figure 1 shows first the main components of the conductor terminal 1. The conductor terminal 1 is formed in the illustrated embodiment as a two-pin connector. For this purpose, the conductor connection terminal 1 has a connector area 6 and a conductor connection area 7 . The conductor connection terminal 1 has an insulating material housing 2 that extends over the connector area 6 and the conductor connection area 7 . The conductor connection terminal 1 also has an actuating lever 5 for each of the two contact inserts arranged in the insulating material housing 2 (as explained below). The operating lever 5 is at the top of the figure 1 shown in the closed position, in the lower part in the open position. In the figure 1 two intersection lines AA and BB are also drawn in, on the basis of which using the figures 2 and 3 the internal structure of the conductor terminal 1 is to be explained. The conductor terminal 1 is constructed in the same way in both areas, ie in the area of the section line BB and the section line AA, so that the statements apply to both areas. It should be noted that the cutting line AA approximately in the middle of the conductor connection area 7 has a vertical offset, so that the section line AA does not reflect a continuous section plane.

Die Figur 2 zeigt den Schnitt entsprechend der Schnittlinie B-B. Hierdurch wird deutlich, dass das Isolierstoffgehäuse 2 zumindest zweiteilig ausgebildet ist, und zwar mit einem Hauptgehäuseteil 20 und einem Deckelteil 21, dass in einer Aussparung des Hauptgehäuseteils 20 eingesetzt ist und darin formschlüssig befestigt ist. Im Inneren des Isolierstoffgehäuses 2 befindet sich im Leiteranschlussbereich 7 ein Kontakteinsatz, der eine Klemmfeder 4 und eine Stromschiene 3 aufweist. Die Klemmfeder 4 weist einen Anlageschenkel 40, eine sich an den Anlageschenkel 40 anschließenden Federbogen 41 und einen sich an den Federbogen 41 anschließenden Klemmschenkel 42 auf. Der Klemmschenkel 42 weist an seinem freien Ende eine Klemmkante 43 auf. Die Stromschiene 3 weist einen Leiteranschlussbereich 30 auf, in dem zum Beispiel eine Sicke angeformt sein kann. Ein elektrischer Leiter kann an einer zwischen der Klemmkante 43 und dem Leiteranschlussbereich 30 gebildeten Klemmstelle festgeklemmt werden. Der elektrische Leiter kann durch eine Leitereinführungsöffnung 22 in das Isolierstoffgehäuse 2 eingeführt werden. Die Leitereinführungsöffnung 22 kann in dem Deckelteil 21 angeordnet sein.the figure 2 shows the section according to section line BB. This makes it clear that the insulating housing 2 is formed at least in two parts, namely with a main housing part 20 and a cover part 21 that is inserted into a recess of the main housing part 20 and is positively secured therein. A contact insert, which has a clamping spring 4 and a busbar 3 , is located in the conductor connection area 7 inside the insulating material housing 2 . The clamping spring 4 has a contact leg 40 , a spring bow 41 adjoining the contact leg 40 and a clamping leg 42 adjoining the spring bow 41 . The clamping leg 42 has a clamping edge 43 at its free end. The conductor rail 3 has a conductor connection area 30 in which a bead can be formed, for example. An electrical conductor can be clamped at a clamping point formed between the clamping edge 43 and the conductor connection area 30 . The electrical conductor can be inserted into the insulating material housing 2 through a conductor insertion opening 22 . The conductor insertion opening 22 can be arranged in the cover part 21 .

In dem Steckverbinderbereich 6 weist die Leiteranschlussklemme 1 einen Steckkontakt auf, der in diesem Ausführungsbeispiel als ein als Gabelkontakt ausgebildeter Buchsenkontakt mit einander gegenüberliegenden Kontaktschenkeln 61, 62 gebildet ist. Die Kontaktgabeln 61, 62 sind über einen vertikal verlaufenden Verbindungsabschnitt 63 miteinander verbunden. Die Stromschiene 3 kann einstückig in Form eines Metallteils mit den Kontaktschenkeln 61, 62 und dem Verbindungsabschnitt 63 ausgebildet sein. Das Isolierstoffgehäuse 2 weist am Ende des Steckverbinderbereichs 6 eine Steckkontakt-Einführungsöffnung 60 auf. Durch diese Steckkontakt-Einführungsöffnung 60 kann ein Kontaktstift oder ein Kontaktmesser eingeführt werden und zwischen den Kontaktschenkeln 61, 62 festgeklemmt werden. Die Anordnung von Buchsenkontakt und Kontaktstift bzw. Kontaktmesser kann alternativ auch vertauscht vorgesehen werden.In the connector area 6, the conductor connection terminal 1 has a plug-in contact, which in this exemplary embodiment is designed as a socket contact designed as a fork contact with contact legs 61, 62 lying opposite one another. The contact forks 61, 62 are connected to one another via a connecting section 63 running vertically. The busbar 3 can be designed in one piece in the form of a metal part with the contact legs 61, 62 and the connecting section 63. The insulating material housing 2 has a plug-in contact insertion opening 60 at the end of the connector area 6 . A contact pin or a contact blade can be inserted through this plug-in contact insertion opening 60 and clamped between the contact legs 61, 62. Alternatively, the arrangement of socket contact and contact pin or contact blade can also be reversed.

Die Leiteranschlussklemme 1 weist außerdem einen Betätigungshebel 5 auf, der zur Betätigung des Klemmschenkels 42 der Klemmfeder 4 dient. Hierzu weist der Betätigungshebel 5 seitlich an Seitenwangen 51 des Betätigungshebels 5 angeordnete Federbetätigungselemente 52 auf, die z.B. als Betätigungsnocken ausgebildet sein können. Wird der Betätigungshebel 5 von der in der Figur 2 dargestellten geschlossenen Stellung in die geöffnete Stellung verschwenkt, so wird der Klemmschenkel 42 mittels der Federbetätigungselemente 52 mitbewegt und hierbei insbesondere von der Stromschiene 3 fortbewegt, sodass die Klemmstelle geöffnet wird.The conductor connection terminal 1 also has an actuating lever 5 which is used to actuate the clamping leg 42 of the clamping spring 4 . For this purpose, the actuating lever 5 has spring actuating elements 52 which are arranged laterally on side walls 51 of the actuating lever 5 and which can be designed, for example, as actuating cams. If the operating lever 5 in the figure 2 pivoted closed position shown in the open position, the clamping leg 42 is moved by means of the spring actuators 52 and in particular moved away from the busbar 3, so that the terminal point is opened.

Der Betätigungshebel 5 erstreckt sich von den Seitenwangen 51 weiter zu einem manuellen Griffbereich 50 hin, an dem der Betätigungshebel 5 manuell betätigt werden kann. Wie erkennbar ist, kann der manuelle Griffbereich 50 über die Außenkontur des Isolierstoffgehäuses 2 hinausragen, sodass er auch in der geschlossenen Stellung leicht gegriffen und aus der geschlossenen Stellung fortbewegt werden kann.The operating lever 5 extends further from the side walls 51 to a manual grip area 50, on which the operating lever 5 can be operated manually. As can be seen, the manual grip area 50 can protrude beyond the outer contour of the insulating material housing 2, so that it can also be easily gripped in the closed position and moved away from the closed position.

Das Deckelteil 21 ist formschlüssig an dem Hauptgehäuseteil 20 befestigt. Hierzu weist das Deckelteil 21 ein Formschlusselement 25 auf, das von einer Rastzunge 23 des Hauptgehäuseteils 20 untergriffen und hintergriffen ist. Die Rastzunge 23 weist insbesondere eine Rastkante 24 auf, mit der das Formschlusselement 25 hintergriffen ist. Auf der gegenüberliegenden Seite weist das Deckelteil 21 ein weiteres Formschlusselement 26 auf, zum Beispiel eine Rastnase, mit dem das Deckelteil 21 zusätzlich mit dem Hauptgehäuseteil 20, und zwar mit einem Halteelement 27 des Hauptgehäuseteils 20, formschlüssig verbunden ist. Das Halteelement 27 kann zum Beispiel als Rastaussparung ausgebildet sein.The cover part 21 is attached to the main housing part 20 in a form-fitting manner. For this purpose, the cover part 21 has a positive-locking element 25 which is gripped under and behind by a latching tongue 23 of the main housing part 20 . The latching tongue 23 has in particular a latching edge 24 with which the positive-locking element 25 is engaged. On the opposite side, the cover part 21 has a further form-fitting element 26, for example a locking lug, with which the cover part 21 is also positively connected to the main housing part 20, namely to a holding element 27 of the main housing part 20. The holding element 27 can be designed as a latching recess, for example.

Eine zusätzliche mechanische Fixierung des Deckelteils 21 wird dadurch realisiert, dass der Betätigungshebel 5 eine Haltekante 54 aufweist, zum Beispiel eine am manuellen Griffbereich 50 angeordnete Haltekante 54, die mit dem Formschlusselement 25 des Deckelteils 21 zusammenwirkt und dieses zumindest in der geschlossenen Stellung des Betätigungshebels 5 hintergreift.An additional mechanical fixation of the cover part 21 is realized in that the actuating lever 5 has a retaining edge 54, for example a retaining edge 54 arranged on the manual grip area 50, which interacts with the form-fitting element 25 of the cover part 21 and this at least in the closed position of the actuating lever 5 behind.

Die Figur 3 zeigt die Leiteranschlussklemme 1 in der Schnittlinie A-A. In dieser Ansicht sind beide in Figur 1 dargestellten Betätigungshebel 5 erkennbar, das heißt der eine in der geschlossenen Stellung angeordnete Betätigungshebel und der andere in der geöffneten Stellung dargestellte Betätigungshebel. Hierdurch wird insbesondere verdeutlich, dass der Betätigungshebel 5 eine sacklochartige Aussparung 53 auf der Unterseite aufweisen kann, an der die Haltekante 54 ausgebildet ist.the figure 3 shows the conductor terminal 1 in section line AA. In this view, both are in figure 1 Actuating lever 5 shown can be seen, i.e. one actuating lever is in the closed position and the other in operating lever shown in the open position. This makes it particularly clear that the actuating lever 5 can have a blind hole-like recess 53 on the underside, on which the retaining edge 54 is formed.

In der Figur 3 ist eine weitere Fixierung des Betätigungshebels 5 am Isolierstoffgehäuse 2, insbesondere am Hauptgehäuseteil 21, erkennbar. Der Betätigungshebel 5 kann, insbesondere am manuellen Griffbereich 50, an einer oder an beiden Seiten seitlich abragende Hebelrastelemente 55 aufweisen, z.B. in Form von Rastzapfen. Diese Hebelrastelemente 55 können mit Gehäuserastelementen, die am Hauptgehäuseteil 20 ausgebildet sind, zur rastenden Fixierung des Betätigungshebels 5 zusammenwirken. Die Gehäuserastelemente 28 können z.B. als Rastaussparungen ausgebildet sein. Dementsprechend können die Rastzapfen in die Rastaussparungen des Hauptgehäuseteils 20 eingreifen, wenn der Betätigungshebel 5 in der geschlossenen Stellung ist.In the figure 3 a further fixation of the actuating lever 5 on the insulating material housing 2, in particular on the main housing part 21, can be seen. The actuating lever 5 can, in particular on the manual grip area 50, have laterally protruding lever latching elements 55 on one or both sides, for example in the form of latching pins. These lever latching elements 55 can interact with housing latching elements, which are formed on the main housing part 20, for the latching fixation of the actuating lever 5. The housing latching elements 28 can be designed as latching recesses, for example. Accordingly, the locking pins can engage in the locking recesses of the main housing part 20 when the operating lever 5 is in the closed position.

Die Figur 4 zeigt das Deckelteil 21 in perspektivischer Darstellung. Erkennbar ist insbesondere die bügelartige oder brückenartige Form des Formschlusselements 25. Unterhalb des Formschlusselements 25 befindet sich ein Freiraum, durch die die Rastzunge 23 des Hauptgehäuseteils 20 gesteckt werden kann.the figure 4 shows the cover part 21 in a perspective view. In particular, the bow-like or bridge-like shape of the form-fitting element 25 can be seen. Below the form-fitting element 25 there is a free space through which the latching tongue 23 of the main housing part 20 can be inserted.

Die Figur 5 zeigt das Deckelteil 21 zusätzlich in seitlicher Schnittdarstellung.the figure 5 shows the cover part 21 additionally in a lateral sectional view.

Wie aus der Figur 6 deutlich wird, können die Hebelrastelemente 55 an beiden Seiten des manuellen Griffbereichs 50 angeordnet sein.How from the figure 6 As will be appreciated, the lever latches 55 may be located on either side of the manual grip portion 50.

Erkennbar ist ferner, dass die Federbetätigungselemente 52 zur Innenseite der Seitenwangen 51 abragen, das heißt zu dem von den Seitenwangen 51 umgebenen Bereich. Alternativ können die beiden Federbetätigungselemente 52 auch zu einem durchgehenden einzelnen Federbetätigungselement verbunden sein. Der Betätigungshebel 5 kann zusätzlich zur definierten Lagerung und Drehführung seitlich abragende Lagerzapfen 56 aufweisen. Diese Lagerzapfen 56 können in entsprechende Lagerungslöcher des Hauptgehäuseteils 20 eingreifen. Alternativ kann der Betätigungshebel 5 auch schwimmend im Isolierstoffgehäuse 2 gelagert sein. In diesem Fall sind die Lagerzapfen 56 nicht erforderlich.It can also be seen that the spring actuating elements 52 protrude towards the inside of the side walls 51, ie towards the area surrounded by the side walls 51. Alternatively, the two spring actuation elements 52 can also be connected to form a continuous individual spring actuation element. In addition to the defined mounting and rotary guidance, the actuating lever 5 can have bearing pins 56 projecting laterally. These bearing journals 56 can engage in corresponding bearing holes in the main housing part 20 . Alternatively, the actuating lever 5 can also be mounted in a floating manner in the insulating material housing 2 . In this case, the bearing pins 56 are not required.

Wie durch die Figuren 8 bis 10 verdeutlich wird, kann eine weitere formschlüssige Kopplung zwischen dem Deckelteil 21 und dem Hauptgehäuseteil 20 durch Seitenfixierelemente 29 realisiert werden. Es sei zunächst davon ausgegangen, dass das Hauptgehäuseteil eine Oberseite 80, eine der Oberseite 80 gegenüberliegende Unterseite 81 und mehrere die Oberseite 80 mit der Unterseite 81 verbindende Vertikalwände 82, 83, 84 aufweist. Hierbei können die Vertikalwände 82, 83 als Seitenwände ausgebildet sein, die das Isolierstoffgehäuse 2 nach außen hin seitlich begrenzen. Im Inneren des Isolierstoffgehäuses 2 kann zumindest eine Zwischenwand als weitere Vertikalwand 84 vorhanden sein. An einer oder mehreren dieser Vertikalwände 82, 83, 84, können wie die Ausschnittsvergrößerung der Figur 10 verdeutlicht, jeweils eines oder mehrere Seitenfixierelemente 29 angeordnet sein. Die Seitenfixierelemente 29 können mit jeweiligen Seitenformschlusselementen 85 des Deckelteils 21 formschlüssig verbunden sein. Auf diese Weise kann insbesondere ein Aufbiegen oder Verbiegen einer Vertikalwand 82, 83, 84 verhindert werden.How through the Figures 8 to 10 becomes clear, a further form-fitting coupling between the cover part 21 and the main housing part 20 can be realized by lateral fixing elements 29 . It is initially assumed that the main housing part has an upper side 80 , an underside 81 opposite the upper side 80 and a plurality of vertical walls 82 , 83 , 84 connecting the upper side 80 to the underside 81 . In this case, the vertical walls 82, 83 can be designed as side walls which laterally delimit the insulating material housing 2 to the outside. At least one intermediate wall can be present as a further vertical wall 84 in the interior of the insulating material housing 2 . On one or more of these vertical walls 82, 83, 84, as the detail enlargement of figure 10 clarifies, one or more side fixing elements 29 may be arranged in each case. The side fixing elements 29 can be connected in a form-fitting manner to the respective side form-fitting elements 85 of the cover part 21 . In this way, in particular, a vertical wall 82, 83, 84 can be prevented from being bent open or bent.

Ein solches Seitenfixierelement 29 kann zum Beispiel als Rastelement ausgebildet sein, beispielsweise mit einer Rastzunge und einem endseitigen Rasthaken, wie insbesondere durch die Figur 10 verdeutlicht wird. Ein solches Rastelement kann dann ein zugeordnetes Seitenformschlusselement 85 hintergreifen.Such a side fixing element 29 can be designed, for example, as a latching element, for example with a latching tongue and an end-side latching hook, as in particular by the figure 10 is made clear. Such a latching element can then engage behind an associated side form-fitting element 85 .
