Der Erfindung liegt die Aufgabe zugrunde, eine solche Leiteranschlussklemme hinsichtlich der mechanischen Robustheit weiter zu verbessern.The invention has for its object to further improve such a conductor terminal with regard to mechanical robustness.
Diese Aufgabe wird bei einer Leiteranschlussklemme der eingangs genannten Art dadurch gelöst, dass
- e) der Betätigungshebel wenigstens eine Haltekante aufweist und
- f) das Deckelteil zumindest bei geschlossenem Betätigungshebel mittels der wenigstens einen Haltekante gegen ein Lösen von dem Hauptgehäuseteil gesichert ist.
- e) the actuating lever has at least one retaining edge and
- f) the cover part is secured against detachment from the main housing part at least when the actuating lever is closed by means of the at least one retaining edge.
Dies hat den Vorteil, dass der Betätigungshebel in die Versteifung und Stabilisierung des mechanischen Aufbaus der Leiteranschlussklemme, insbesondere des Isolierstoffgehäuses, eingebunden wird und somit außer der Funktion zur Betätigung der Klemmfeder eine zusätzliche Funktion aufweist, nämlich die Erhöhung der mechanischen Stabilität der Leiteranschlussklemme. Wenn auf das Deckelteil eine Zugkraft aufgebracht wird, zum Beispiel dadurch, dass von außen an dem am Kontakteinsatz angeklemmten elektrischen Leiter gezogen wird, so kann sich bei der vorliegenden Erfindung das Deckelteil zusätzlich zu anderen Fixierelementen, wie zum Beispiel der formschlüssigen Fixierung mittels des Formschlusselements, an der durch die Haltekante des Betätigungshebels bereit gestellten weiteren Fixierung abstützen und hierüber die Kräfte auf andere Teile des Isolierstoffgehäuses übertragen.

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 connecting terminal, in particular of the insulating material housing, and thus has an additional function in addition to the function for actuating the clamping spring, namely increasing the mechanical stability of the conductor connecting terminal. If a tensile force is applied to the cover part, for example by pulling from the outside on the electrical conductor clamped on the contact insert, then in the present invention the cover part can, in addition to other fixing elements, such as for example the positive fixing by means of the positive locking element, Support on the further fixation provided by the holding edge of the actuating lever and transfer the forces to other parts of the insulating material housing. In this way, loosening or pulling out 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 terminal can be increased.

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 form-locking element is used to fix the cover part to the main housing part. Such a form-locking element can be designed, for example, as a locking element, so that the cover part can be fixed to the housing part by means of locking by means of this form-locking element or locking element. The at least one form-locking element can be an integral part of the cover part, e.g. in that the at least one form-locking element is formed in one piece with the cover part. The cover part can, for example, have a corresponding counter contour which interacts with the holding edge for securing 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 arch adjoining the contact leg and a clamping leg adjoining the spring arch. The clamping leg can have a clamping edge at its free end ends that serve to clamp the electrical conductor. The contact leg serves for the mechanical fastening and support of the clamping spring on at least part of the conductor connection terminal, for example on the actuating lever, on a busbar and / or on the insulating material housing. The contact insert can additionally have, for example, a busbar 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, the closed position of the actuating lever can correspond to a closed clamping point. When the clamping point is closed, an electrical conductor is clamped by means of the clamping spring; when the clamping point is open, the electrical conductor can be removed from the clamping point essentially without effort or inserted into the clamping point.
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. In order to at least largely close this recess or opening, the cover part is used, which can, for example, be fully or partially inserted into the recess or opening and can be fixed therein. In order to be able to insert the electrical conductor to be clamped 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 adjoining the conductor insertion opening, through which an electrical conductor can be guided specifically to the clamping point.
Gemäß einer vorteilhaften Ausgestaltung 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 an advantageous embodiment of the invention, it is provided that the cover part is secured against detaching from the main housing part at least when the actuating lever is closed by means of the at least one retaining edge in that the at least one form-locking element of the cover part is encompassed by the at least one holding edge. In this way, the positive locking element, which already serves to fix the cover part on the main housing part, is additionally used for the fixation between the actuating lever and the cover part. Accordingly, in this embodiment, the mentioned 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 on the contact insert can be fixed by spring force by means of the clamping spring, a tensile force exerted on the electrical conductor outside the conductor connecting terminal being transferable to the contact insert and from there to the cover part and from the cover part to the actuating lever . Due to the power chain formed in this way, the tensile force exerted on the electrical conductor can 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 the conductor connection terminal can be transmitted from the actuating lever to the main housing part. In this way, the aforementioned power chain can be continued up to the main housing part, that is to say to a point at which the actuating 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 actuation area on which at least one spring actuation element is arranged for deflecting the clamping spring, and a manual grip area on which the actuation lever is to be operated manually, the holding edge being arranged in the manual grip area is. In this way, the holding edge can be arranged at a suitable point on the actuating lever without affecting the areas of the actuating lever which affect the actuating mechanism of the clamping spring or which may have 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 holding edge can be arranged, so to speak, on the inside of the actuation lever and in particular on the inside of the manual actuation area. In this way, the fixing of the cover part by means of the actuating lever can be made particularly efficient. In addition, this fixation is not disturbing for the manual actuation of the actuation lever and the visual appearance of the conductor connection 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 actuating lever or the manual actuating region.
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 an area of the form-locking element of the cover part protruding from the main housing part projects into the recess in the closed state of the actuating lever. 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 implemented 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 locked in place on the main housing part at least in the closed position. This can ensure that the actuating lever remains in the closed position in a defined manner, even if the conductor connecting terminal is loaded, 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 latch element which is designed to interact with at least one lever latch element arranged on the actuating lever. As a result, the actuating lever can be locked in place, at least in the closed position, by the cooperation of the lever locking element with the housing locking element. Furthermore, by the interaction of the lever latching element with the housing latching element, a transmission of the tensile force exerted on the electrical conductor outside of the conductor connecting terminal from the actuating lever to the main housing part can be ensured in a simple manner.
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 locking element can be designed as a locking recess assigned to the respective lever locking element in a side wall of the main housing part. 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 attached to the main housing part, engages under the form-locking element of the cover part and engages behind with a latching edge. This enables the cover part to be reliably fixed to the main housing part. For example, the main housing part on the side facing the actuating lever can have a latching tongue projecting parallel to the direction of insertion of the conductor with an end latching hook. In this case, the form-locking element of the cover part can be designed, for example, as a bow-shaped retaining tab, which is latched under and behind the latching tongue with its latching hook at the end. The locking edge is thus formed on the locking 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 spaced apart locations.
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 protrudes from the main housing part at least in the open position and a lower side opposite the upper side, the main housing part having a plurality of vertical walls connecting the upper side to the underside, wherein a side fixing element is arranged on at least one vertical wall, by means of which the cover part can be fixed laterally by positive locking on the main housing part. Hereby 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 to 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 positive locking element assigned to the side fixing element can be arranged on the cover part, with which the positive connection to the side fixing element is produced when the cover part is attached to the main housing part. The form-fitting connection can be designed, for example, as a latching connection, in which case the side fixing element can be designed as a latching element, for example with a latching tongue aligned parallel to the direction of insertion of the conductor, with an end latching hook. Another possible implementation for the side fixing element is the design as a locking 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 limit the main housing part to the outside. If the conductor connection terminal is designed as a multi-pole conductor connection terminal that has a plurality of conductor connection chambers that are separate from one another, the insulating material housing can also form inner partition walls in addition to the side walls, through which additional vertical walls can be realized. The side fixing elements mentioned can also be implemented 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:
- a) wenigstens ein Isolierstoffgehäuse, das wenigstens eine Leitereinführungsöffnung zum Einführen eines elektrischen Leiters in das Isolierstoffgehäuse aufweist,
- b) wenigstens einen Kontakteinsatz, der zumindest überwiegend innerhalb des Isolierstoffgehäuses angeordnet ist und der wenigstens eine Klemmfeder aufweist,
- c) wenigstens einen Betätigungshebel, durch den die Klemmfeder ausgelenkt werden kann, wobei der Betätigungshebel zumindest von einer geöffneten in eine geschlossene Stellung und umgekehrt verschwenkbar ist,
- d) wobei das Isolierstoffgehäuse als separate Bauteile wenigstens ein Hauptgehäuseteil und ein Deckelteil aufweist, das an dem Hauptgehäuseteil mittels wenigstens eines Formschlusselements formschlüssig fixierbar ist,
- a) at least one insulating material housing which has at least one conductor insertion opening for inserting an electrical conductor into the insulating material housing,
- b) at least one contact insert which is at least predominantly arranged within the insulating material housing and which has at least one clamping spring,
- c) at least one actuating lever through which the clamping spring can be deflected, the actuating lever being pivotable at least from an open to a closed position and vice versa,
- d) the insulating material housing, as separate components, has at least one main housing part and a cover part which can be positively fixed to the main housing part by means of at least one form-locking element,
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°).For the purposes of the present invention, the indefinite term "a" is not to be understood as a numerical word. So if e.g. When one speaks of a component, this should be interpreted in the sense of "at least one component". Insofar as angles are given in degrees, they refer to a circular dimension of 360 degrees (360 °).

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
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.

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
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.
