Description

Die Erfindung betrifft eine Anschlussanordnung zum Anschließen eines elektrischen Leiters, welche einen Strombalken, einen Zugbügel und eine Druckfeder aufweist, wobei der Zugbügel zwei parallel zueinander angeordnete Klemmschenkel und einen die beiden Klemmschenkel miteinander verbindenden Verbindungssteg aufweist, wobei die Klemmschenkel jeweils eine Durchführungsöffnung aufweisen, durch welche der Strombalken hindurchgeführt ist und durch welche der anzuschließende Leiter in einer Klemmstellung derart geführt ist, dass der Leiter gegen den Strombalken geklemmt ist, und wobei die Druckfeder zwischen dem Verbindungssteg des Zugbügels und dem Strombalken angeordnet ist und bei einer Bewegung des Zugbügels von der Klemmstellung in eine Offenstellung zusammendrückbar ist. Ferner betrifft die Erfindung eine Anschlussklemme, welche ein Isolierstoffgehäuse und mindestens eine derart ausgebildete, in dem Isolierstoffgehäuse angeordnete Anschlussanordnung aufweist.The invention relates to a connection arrangement for connecting an electrical conductor, which has a current bar, a clamping bracket and a compression spring, the clamping bracket having two clamping legs arranged parallel to one another and a connecting web connecting the two clamping legs to one another, the clamping legs each having a feed-through opening through which the current bar is passed through and through which the conductor to be connected is guided in a clamped position in such a way that the conductor is clamped against the current bar, and wherein the compression spring is arranged between the connecting web of the tension bar and the current bar and when the tension bar moves from the clamped position to an open position is compressible. Furthermore, the invention relates to a connection terminal which has an insulating material housing and at least one connection arrangement designed in this way and arranged in the insulating material housing.

Anschlussklemmen mit einer derartigen Anschlussanordnung werden häufig als Hochstromklemmen eingesetzt, bei welchen Leiter mit einem relativ großen Querschnitt von vorzugsweise 35 mm2 bis 150 mm2 angeschlossen werden können. Derartige Anschlussanordnungen weisen Zugbügelanschlüsse auf, die aus einem U-förmigen Zugbügel und einer Druckfeder ausgebildet sind. Die Druckfeder ist dabei derart in dem Zugbügel angeordnet, dass sie das untere Ende des Zugbügels gegen die Unterseite eines Strombalkens zieht, so dass ein dort durch eine Durchtrittsöffnung im Klemmschenkel des Zugbügels eingeführter elektrischer Leiter gegen die Unterseite des sich durch die Durchtrittsöffnungen der Klemmschenkel des Zugbügels erstreckenden Strombalkens festgeklemmt wird. Derartige Anschlussklemmen sind beispielsweise aus der EP 1 798 819 B1 und der DE 10 2015 112433 A1 bekannt. Nachteilig ist, dass das Öffnen der Klemmstelle eines derartigen Zugbügelanschlusses, wozu die Druckfeder axial zusammengedrückt werden muss, bei derartigen Anschlussanordnungen häufig nur mit Hilfe von unterstützenden Betätigungselementen möglich ist, so dass ein Anschließen eines Leiters einen erhöhten Aufwand für den Nutzer erfordert.Connection terminals with such a connection arrangement are often used as high-current terminals, in which conductors with a relatively large cross-section of preferably 35 mm 2 to 150 mm 2 can be connected. Connection arrangements of this type have clamping bracket connections which are formed from a U-shaped clamping bracket and a compression spring. The compression spring is arranged in the clamping yoke in such a way that it pulls the lower end of the clamping yoke against the underside of a current bar, so that an electrical conductor inserted there through a passage opening in the clamping limb of the clamping yoke against the underside of the through-openings in the clamping limb of the clamping yoke extending current bar is clamped. Such terminals are for example from EP 1 798 819 B1 and the DE 10 2015 112433 A1 known. The disadvantage is that opening the terminal point of such a clamping bracket connection, for which the compression spring must be axially compressed, is often only possible with such connection arrangements with the aid of supporting actuating elements, so that connecting a conductor requires more effort for the user.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Anschlussanordnung sowie eine Anschlussklemme zur Verfügung zu stellen, bei welchen der Aufwand zum Anschließen eines Leiters für einen Nutzer reduziert werden kann.The invention is therefore based on the object of making available a connection arrangement and a connection terminal in which the outlay for connecting a conductor can be reduced for a user.

Die Aufgabe wird erfindungsgemäß mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the invention with the features of independent claim 1 . Expedient configurations and advantageous developments of the invention are specified in the dependent claims.

Die Anschlussanordnung gemäß der Erfindung zeichnet sich dadurch aus, dass der Zugbügel mindestens eine in einen zwischen den beiden Klemmschenkeln ausgebildeten Klemmraum hineinragende Klemmlasche aufweist, welche eine Einführschräge zum Einführen des anzuschließenden Leiters in den Klemmraum ausbildet und mittels welcher der Leiter in der Klemmstellung gegen den Strombalken geklemmt ist.The connection arrangement according to the invention is characterized in that the clamping bracket has at least one clamping lug which projects into a clamping space formed between the two clamping legs, which forms an insertion bevel for inserting the conductor to be connected into the clamping space and by means of which the conductor in the clamping position against the current bar is stuck.

Erfindungsgemäß weist der Zugbügel nunmehr eine Klemmlasche auf, welche derart in einen zwischen den beiden Klemmschenkeln des Zugbügels ausgebildeten Klemmraum bzw. Freiraum hineinragt, dass diese eine Einführschräge für einen anzuschließenden Leiter beim Einführen des Leiters in den Klemmraum ausbilden kann. Die Klemmlasche ragt dafür vorzugsweise schräg bzw. winklig in den Klemmraum hinein, indem die Klemmlasche relativ zu den Klemmschenkeln abgewinkelt bzw. schräg angeordnet ist. Beim Einführen eines Leiters in den Klemmraum stößt dieser damit vorzugsweise gegen die Klemmlasche und gleitet entlang der Klemmlasche in den Klemmraum hinein. Dadurch kann der Leiter beim Einführen in den Klemmraum einen Druck auf die Klemmlasche und damit auf den Zugbügel ausüben, wodurch eine selbsttätige Bewegung des Zugbügels in eine Offenstellung erfolgen kann. Damit kann der Zugbügel und damit die gesamte Anschlussanordnung direktsteckbar ausgebildet sein, so dass ein Anschließen eines Leiters ohne die Zuhilfenahme eines zusätzlichen Werkzeuges zur Überführung des Zugbügels in die Offenstellung erfolgen kann. Damit ist ein werkzeugloses Direktstecken insbesondere von starren Leitern möglich. Die Klemmlasche ist dabei derart ausgebildet, dass diese zusätzlich zu der Ausbildung als Einführhilfe auch eine Klemmung des in den Klemmraum eingeführten Leiters gegen den Strombalken ermöglichen kann, indem der in den Klemmraum eingeführte Leiter mittels der Klemmlasche gegen den Strombalken gedrückt werden kann. Durch das Hineinragen in den Klemmraum bildet die gegen den angeschlossenen Leiter drückende Klemmlasche eine Art Auszugsstopp für den Leiter aus, so dass der Leiter nicht ungewollt aus dem Klemmraum herausgezogen werden kann, da die Klemmlasche sich mit dem angeschlossenen Leiter verkeilen kann.According to the invention, the clamping bracket now has a clamping lug which protrudes into a clamping space or free space formed between the two clamping legs of the clamping bracket in such a way that it can form an insertion bevel for a conductor to be connected when the conductor is inserted into the clamping space. For this purpose, the clamping lug preferably protrudes obliquely or at an angle into the clamping space, in that the clamping lug is arranged at an angle or at an angle relative to the clamping legs. When a conductor is inserted into the clamping space, it preferably hits the clamping lug and slides along the clamping lug into the clamping space. As a result, when the conductor is inserted into the clamping space, it can exert pressure on the clamping lug and thus on the clamping bracket, as a result of which the clamping bracket can move automatically into an open position. The clamping bracket and thus the entire connection arrangement can thus be designed so that they can be plugged in directly, so that a conductor can be connected without the aid of an additional tool for moving the clamping bracket into the open position. This enables direct plugging, especially of rigid conductors, without the use of tools. The clamping lug is designed in such a way that, in addition to being designed as an insertion aid, it can also clamp the conductor inserted into the terminal space against the current bar, in that the conductor inserted into the terminal space can be pressed against the current bar by means of the clamping lug. By protruding into the clamping space, the clamping lug pressing against the connected conductor forms a kind of pull-out stop for the conductor, so that the conductor cannot be unintentionally pulled out of the clamping space, since the clamping lug can become wedged with the connected conductor.

Um ein direktsteckendes Einführen eines anzuschließenden Leiters in den Klemmraum besonders leicht ermöglichen zu können, ragt die mindestens eine Klemmlasche bevorzugt in einem Winkel von 10° ≤ α ≤ 70°, besonders bevorzugt in einem Winkel von 30° ≤ α ≤ 50°, zu einer Längserstreckung der Klemmschenkel bzw. zu einer Längserstreckung einer der Klemmschenkel in den Klemmraum hinein. Die Klemmlasche erstreckt sich damit vorzugsweise winklig zu einer Längserstreckung der Klemmschenkel in den Klemmraum hinein.In order to be able to easily insert a conductor to be connected directly into the terminal space, the at least one clamping lug preferably protrudes at an angle of 10°≦α≦70°, particularly preferably at an angle of 30°≦α≦50° Longitudinal extent of the clamping legs or to a longitudinal extent of one of the clamping legs into the terminal space. The clamping lug thus preferably extends at an angle to a longitudinal extension of the clamping legs into the clamping space.

Angeordnet ist die Klemmlasche vorzugsweise an einem der beiden Klemmschenkel des Zugbügels. Die Klemmlasche erstreckt sich damit vorzugsweise ausgehend von einem der Klemmschenkel in den Klemmraum hinein. Bevorzugt ist die Klemmlasche an dem Klemmschenkel angeordnet, durch dessen Durchführungsöffnung der anzuschließende Leiter in Einführungsrichtung zuerst eingeführt wird und welcher damit näher an der Leitereinführungsöffnung eines Isolierstoffgehäuses einer Anschlussklemme angeordnet ist.The clamping lug is preferably arranged on one of the two clamping legs of the clamping bracket. The clamping lug thus preferably extends into the clamping space, starting from one of the clamping legs. The clamping lug is preferably arranged on the clamping leg through whose feed-through opening the conductor to be connected is inserted first in the direction of insertion and which is therefore arranged closer to the conductor insertion opening of an insulating material housing of a connection terminal.

Vorzugsweise ist die mindestens eine Klemmlasche möglichst nah an einer Durchführungsöffnung eines Klemmschenkels angeordnet, um das Einführen für den anzuschließenden Leiter erleichtern zu können. Die mindestens eine Klemmlasche kann sich bevorzugt ausgehend von einem die Durchführungsöffnung einer der beiden Klemmschenkel begrenzenden Randbereich in den Klemmraum hineinerstrecken. Der Randbereich der Durchführungsöffnung bildet vorzugsweise eine Unterkante der Durchführungsöffnung auf, welche in Richtung des Strombalkens gerichtet ist.The at least one clamping lug is preferably arranged as close as possible to a lead-through opening of a clamping leg in order to be able to facilitate insertion of the conductor to be connected. The at least one clamping lug can preferably extend into the clamping space, starting from an edge region delimiting the feed-through opening of one of the two clamping legs. The edge area of the feed-through opening preferably forms a lower edge of the feed-through opening, which is directed in the direction of the current bar.

Damit die Klemmlasche eine besonders gute Selbsthemmung zur Ausbildung eines Auszugsstopps des angeschlossenen Leiters aus dem Klemmraum ausbilden kann, kann die mindestens eine Klemmlasche relativ zu den beiden Klemmschenkeln schwenkbeweglich gelagert sein. Durch die schwenkbewegliche Lagerung kann die Klemmlasche beim Einführen eines Leiters in den Klemmraum weiter in den Klemmraum hineinverschwenkt werden, um das Einführen eines Leiters zu erleichtern. Ist der Leiter eingeführt und angeschlossen, ermöglicht die schwenkbare Anordnung der Klemmlasche eine Selbsthemmung, da bei einem Herausziehen des Leiters aus dem Klemmraum die Klemmlasche durch die Verschwenkmöglichkeit umso stärker gegen Leiter gedrückt werden kann und damit stärker mit dem Leiter verkeilen kann, so dass ein ungewolltes Herausziehen des Leiters besonders sicher verhindert werden kann. Zur Ausbildung einer schwenkbeweglichen Lagerung kann der Zugbügel beispielsweise eine Drehachse aufweisen, an welcher die mindestens eine Klemmlasche schwenkbeweglich gelagert sein kann. Die Drehachse kann als Achskörper ausgebildet sein, welcher sich vorzugsweise quer zur Längserstreckung einer der Klemmschenkel erstrecken kann. Die Drehachse kann sich vorzugsweise zwischen zwei sich gegenüberliegenden, eine Durchführungsöffnung eines Klemmschenkels begrenzenden Randbereichen erstrecken. Die Klemmlasche kann eine Öffnung aufweisen, durch welche die Drehachse hindurchgeführt sein kann, so dass die Drehachse durch die Klemmlasche hindurchgeführt sein kann.In order for the clamping lug to be able to form a particularly good self-locking mechanism to stop the connected conductor from being pulled out of the terminal space, the at least one clamping lug can be mounted so that it can pivot relative to the two clamping legs. Due to the pivotable mounting, the clamping lug can be pivoted further into the clamping space when inserting a conductor into the clamping space in order to facilitate the insertion of a conductor. Once the conductor has been inserted and connected, the pivoting arrangement of the clamping shackle enables self-locking, since when the conductor is pulled out of the terminal space, the clamping shackle can be pressed all the more strongly against the conductor due to the pivoting option and can therefore become more wedged with the conductor, so that an unwanted Pulling out of the conductor can be prevented particularly safely. In order to form a pivotable mounting, the tension bracket can have, for example, an axis of rotation on which the at least one clamping lug can be mounted in a pivotable manner. The axis of rotation can be designed as an axis body, which can preferably extend transversely to the longitudinal extent of one of the clamping legs. The axis of rotation can preferably extend between two opposite edge regions delimiting a feed-through opening of a clamping leg. The clamping strap can have an opening through which the axis of rotation can be guided, so that the axis of rotation can be guided through the clamping strap.

Bevorzugt kann der Zugbügel einen Begrenzungsanschlag zur Begrenzung der Schwenkbewegung der mindestens einen Klemmlasche aufweisen. Der Begrenzungsanschlag ist vorzugsweise derart ausgebildet, dass dieser ein zu weites Einschwenken der Klemmlasche in den Klemmraum verhindern kann.The tension bracket can preferably have a limit stop for limiting the pivoting movement of the at least one clamping lug. The limit stop is preferably designed in such a way that it can prevent the clamping lug from swiveling in too far into the clamping space.

Die Lösung der erfindungsgemäßen Aufgabe erfolgt ferner mittels einer Anschlussklemme, welche ein Isolierstoffgehäuse und mindestens eine in dem Isolierstoffgehäuse angeordnete Anschlussanordnung aufweist, welche wie vorstehend beschrieben, aus- und weitergebildet sein kann.The object according to the invention is also achieved by means of a connection terminal which has an insulating material housing and at least one connection arrangement which is arranged in the insulating material housing and which can be designed and developed as described above.

Eine derartige Anschlussklemme kann eine oder mehrere derartige Anschlussanordnungen aufweisen. Weist die Anschlussklemme zwei derartiger Anschlussanordnungen auf, so kann die Anschlussklemme beispielsweise eine Reihenklemme ausbilden, welche auf einer Tragschiene aufgerastet werden kann.Such a connection terminal can have one or more such connection arrangements. If the connection terminal has two such connection arrangements, the connection terminal can, for example, form a terminal block which can be snapped onto a mounting rail.

Nachfolgend wird die Erfindung unter Bezugnahme auf die anliegenden Zeichnungen anhand bevorzugter Ausführungsformen näher erläutert.The invention is explained in more detail below with reference to the attached drawings using preferred embodiments.

Fig. 1 zeigt schematisch eine Anschlussklemme 200 mit einem Isolierstoffgehäuse 210, innerhalb welchem zwei Anschlussanordnungen 100 zum Anschließen jeweils eines elektrischen Leiters 300 angeordnet sind. Die Anschlussklemme 200 ist hier in Form einer Reihenklemme ausgebildet, welche auf einer Tragschiene angeordnet werden kann. In dem Isolierstoffgehäuse 210 sind zwei Leitereinführungsöffnungen 211 ausgebildet, über welche jeweils ein anzuschließender Leiter 300 in das Isolierstoffgehäuse 210 hin zu der jeweiligen Anschlussanordnung 100 geführt werden kann. 1 shows schematically a terminal 200 with an insulating housing 210, within which two terminal assemblies 100 for connecting an electrical conductor 300 are arranged. The connection terminal 200 is designed here in the form of a terminal block, which can be arranged on a mounting rail. Two conductor insertion openings 211 are formed in the insulating material housing 210, via which a conductor 300 to be connected can be guided into the insulating material housing 210 towards the respective connection arrangement 100.

Die Anschlussanordnungen 100 weisen jeweils einen Strombalken 110 auf, welche hier einstückig miteinander verbunden sind.The connection arrangements 100 each have a current bar 110 which is connected to one another in one piece here.

Ferner weisen die Anschlussanordnungen 100 jeweils einen Zugbügel 111 und eine Druckfeder 112 auf, wobei der Zugbügel 111 zusammen mit der Druckfeder 112 einen Zugbügelanschluss ausbilden.Furthermore, the connection arrangements 100 each have a tension yoke 111 and a compression spring 112, the tension yoke 111 together with the compression spring 112 forming a tension yoke connection.

Der Zugbügel 111 weist jeweils zwei parallel zueinander angeordnete Klemmschenkel 113, 114 auf. Die beiden Klemmschenkel 113, 114 sind an ihrem oberen Ende über einen Verbindungssteg 115 miteinander verbunden. Durch die beiden Klemmschenkel 113, 114 und den Verbindungssteg 115 weist der Zugbügel 111 eine U-Form auf.The tension bracket 111 has two clamping legs 113, 114 arranged parallel to one another. The two clamping legs 113, 114 are connected to one another at their upper end via a connecting web 115. Due to the two clamping legs 113, 114 and the connecting web 115, the clamping bracket 111 has a U-shape.

An den beiden Klemmschenkeln 113, 114 ist jeweils eine Durchführungsöffnung 116, 117 ausgebildet, wie beispielsweise in Fig. 4 zu erkennen ist. Durch die Durchführungsöffnungen 116, 117 ist der Strombalken 110 hindurchgeführt, so dass der Strombalken 110 durch den Zugbügel 111 hindurchragt. Ferner wird ein anzuschließender Leiter 300 durch die beiden Durchführungsöffnungen 116, 117 der Klemmschenkel 113, 114 hindurchgeführt, wie in Fig. 2 und 3 zu erkennen ist. Durch die Durchführungsöffnungen 116, 117 kann der Zugbügel 111 mit seinen Klemmschenkeln 113, 114 auf dem Strombalken 110 aufsitzen.A feed-through opening 116, 117 is formed on each of the two clamping legs 113, 114, such as in FIG 4 can be seen. The current bar 110 is passed through the lead-through openings 116 , 117 , so that the current bar 110 protrudes through the tension bracket 111 . Furthermore, a Conductor 300 to be connected passed through the two lead-through openings 116, 117 of the clamping legs 113, 114, as in 2 and 3 can be seen. Through the lead-through openings 116, 117, the clamping limbs 113, 114 of the clamping bracket 111 can be seated on the current bar 110.

Der Zugbügel 111 ist relativ zu dem Strombalken 110 bewegbar bzw. verschiebbar angeordnet. Die Bewegungsrichtung B des Zugbügels 111 ist quer zur Einführungsrichtung E eines Leiters 300 in die Anschlussanordnung 100 bzw. in die Anschlussklemme 200 ausgebildet. Durch die Bewegung des Zugbügels 111 kann dieser in eine Klemmstellung, wie sie in Fig. 3 gezeigt ist, und in eine Offenstellung, wie sie in Fig. 2 gezeigt ist, überführt werden. Betätigt werden kann der Zugbügel 111 über ein Werkzeug 400, welches über eine Öffnung 212 an dem Isolierstoffgehäuse 210 in das Isolierstoffgehäuse 210 eingeführt werden kann, um den Zugbügel 111 durch Aufbringen einer Druckkraft auf den Verbindungssteg 115 des Zugbügels 111 betätigen zu können. Das Werkzeug 400 kann beispielsweise ein Schraubendreher sein.The tension bracket 111 is arranged to be movable or displaceable relative to the current bar 110 . The direction of movement B of the tension bracket 111 is transverse to the direction E of insertion of a conductor 300 into the connection arrangement 100 or into the connection terminal 200 . By moving the clamping bracket 111, it can be moved into a clamping position, as shown in 3 is shown, and in an open position as shown in 2 is shown to be transferred. The clamping bracket 111 can be actuated using a tool 400, which can be inserted into the insulating material housing 210 via an opening 212 on the insulating material housing 210 in order to be able to actuate the clamping bracket 111 by applying a compressive force to the connecting web 115 of the clamping bracket 111. The tool 400 can be a screwdriver, for example.

Die Druckfeder 112 ist in Form einer Spiralfeder ausgebildet. Die Druckfeder 112 ist zwischen dem Verbindungssteg 115 des Zugbügels 111 und dem Strombalken 110 angeordnet. Um einen angeschlossenen Leiter 300 freizugeben, wird die Druckfeder 112 bei der Bewegung des Zugbügels 111 von der Klemmstellung in die Offenstellung zusammengedrückt. Dies erfolgt durch Aufbringen einer Druckkraft mittels des Werkzeugs 400 auf den Zugbügel 111 und damit auf die Druckfeder 112.The compression spring 112 is designed in the form of a spiral spring. The compression spring 112 is arranged between the connecting web 115 of the tension bracket 111 and the current bar 110 . In order to release a connected conductor 300, the compression spring 112 is compressed during the movement of the clamping bracket 111 from the clamped position into the open position. This is done by applying a compressive force using tool 400 to tension bracket 111 and thus to compression spring 112.

Beim Einführen eines anzuschließenden Leiters 300 in den Anschlussanordnung 100 ist hingegen keine Betätigung des Zugbügels 111 mittels des Werkzeugs 400 erforderlich, da der Zugbügel 111 eine Klemmlasche 118 aufweist, welche in einen zwischen den beiden Klemmschenkeln 113, 114 ausgebildeten Klemmraum 119 hineinragt. Die Klemmlasche 118 bildet eine Einführschräge zum Einführen des anzuschließenden Leiters 300 in den Klemmraum 119 aus, entlang welcher der anzuschließende Leiter 300 entlanggleiten kann und dadurch eine Druckkraft auf die Klemmlasche 118 und damit auf den Zugbügel 111 ausüben kann, wodurch der Zugbügel 111 derart bewegt werden kann, dass die Durchführungsöffnungen 116, 117 freigegeben werden und dadurch der anzuschließende Leiter 300 durch die Durchführungsöffnungen 116, 117 hindurchgeführt werden kann. Dies ermöglicht ein Direktstecken eines Leiters 300, so dass ein werkzeugloses Anschließen eines Leiters 300 ermöglicht wird.When inserting a conductor 300 to be connected into the connection arrangement 100, on the other hand, the clamping bracket 111 does not have to be actuated by means of the tool 400, since the clamping bracket 111 has a clamping lug 118 which protrudes into a clamping space 119 formed between the two clamping legs 113, 114. The clamping lug 118 forms an insertion bevel for inserting the conductor 300 to be connected into the clamping space 119, along which the conductor 300 to be connected can slide and thereby exert a compressive force on the clamping lug 118 and thus on the tension bracket 111, as a result of which the tension bracket 111 is moved in this way can that the feed-through openings 116, 117 are released and thereby the conductor 300 to be connected can be passed through the feed-through openings 116, 117. This enables a conductor 300 to be plugged in directly, so that a conductor 300 can be connected without the use of tools.

Die Klemmlasche 118 ist, wie in Fig. 2 eingezeichnet ist, in einem Winkel von 10° ≤ α ≤ 70° zur Längserstreckung L der Klemmschenkel 113, 114 angeordnet. Bei der hier gezeigten Ausgestaltung ist die Klemmlasche 118 ungefähr in einem Winkel α von circa 45° zur Längserstreckung L der Klemmschenkel 113, 114 angeordnet.The clamping lug 118 is, as in 2 is drawn in, at an angle of 10°≦α≦70° to the longitudinal extent L of the clamping legs 113, 114. In the embodiment shown here, the clamping lug 118 is arranged approximately at an angle α of approximately 45° to the longitudinal extent L of the clamping legs 113, 114.

Die Klemmlasche 118 weist an ihrem freien Ende eine Klemmkante 120 auf, mittels welcher der Leiter 300 in der Klemmstellung gegen den Strombalken 110 geklemmt wird, wie in Fig. 3 zu erkennen ist.The clamping lug 118 has a clamping edge 120 at its free end, by means of which the conductor 300 is clamped in the clamped position against the current bar 110, as shown in FIG 3 can be seen.

Die Klemmlasche 118 ist an einem der beiden Klemmschenkel 113, 114 angeordnet, wobei die Klemmlasche 118 hier an dem Klemmschenkel 113 angeordnet ist, welcher näher zu der jeweiligen Leitereinführungsöffnung 211 positioniert ist. Die Klemmlasche 118 ist ausgehend von dem jeweiligen Klemmschenkel 113 in Richtung des Strombalkens 110 gerichtet, so dass die Klemmlasche 118 in Richtung Strombalken 110 zeigt. Die Klemmkante 120 an der Klemmlasche 118 ist ebenfalls in Richtung Strombalken 110 gerichtet.The clamping lug 118 is arranged on one of the two clamping limbs 113, 114, the clamping lug 118 being arranged here on the clamping limb 113 which is positioned closer to the respective conductor insertion opening 211. Starting from the respective clamping leg 113 , the clamping lug 118 is directed in the direction of the current bar 110 , so that the clamping lug 118 points in the direction of the current bar 110 . The clamping edge 120 on the clamping lug 118 is also directed in the direction of the current bar 110 .

Die Klemmlasche 118 erstreckt sich in etwa bis hin zu einer Mitte des Klemmraums 119 zwischen den beiden Klemmschenkeln 113, 114.The clamping lug 118 extends approximately to the middle of the clamping space 119 between the two clamping legs 113, 114.

Die Klemmlasche 118 kann sich ausgehend von einem die Durchführungsöffnung 116, 117 einer der beiden Klemmschenkel 113, 114 begrenzenden Randbereich in den Klemmraum 119 erstrecken. Der Randbereich kann eine Unterkante der Durchführungsöffnung 116, 117 ausbilden, welche in Richtung des Strombalkens 110 zeigt.The clamping lug 118 can extend into the clamping space 119 starting from an edge region delimiting the feed-through opening 116, 117 of one of the two clamping legs 113, 114. The edge area can form a lower edge of the feedthrough opening 116, 117, which points in the direction of the current bar 110.

Fig. 4 zeigt eine Ausgestaltung, bei welcher die Klemmlasche 118 relativ zu den beiden Klemmschenkeln 113, 114 schwenkbeweglich gelagert ist. Der Zugbügel 111 weist dafür eine Drehachse 121 auf, an welcher die Klemmlasche 118 schwenkbeweglich gelagert ist. Die Drehachse 121 ist als Achskörper ausgebildet, welcher sich quer zur Längserstreckung L der Klemmschenkel 113, 114 erstreckt. Die Drehachse 121 erstreckt sich zwischen zwei sich gegenüberliegenden, die Durchführungsöffnung 116, 117 eines Klemmschenkels 113, 114 begrenzenden Randbereichen 122, 123. 4 shows an embodiment in which the clamping lug 118 is mounted pivotably relative to the two clamping legs 113, 114. For this purpose, the tension bracket 111 has an axis of rotation 121 on which the clamping lug 118 is pivotably mounted. The axis of rotation 121 is designed as an axis body which extends transversely to the longitudinal extension L of the clamping legs 113 , 114 . The axis of rotation 121 extends between two opposite edge regions 122, 123 delimiting the feed-through opening 116, 117 of a clamping leg 113, 114.

Bei der in Fig. 4 gezeigten Ausgestaltung wird die Klemmlasche 118 bei Einführen eines Leiters 300 gegen den Uhrzeigersinn weiter in den Klemmraum 119 hinein verschwenkt, um den Leiter 300 in den Klemmraum 119 einführen zu können. Ist der Leiter 300 eingeführt und angeschlossen, ermöglicht die schwenkbare Anordnung der Klemmlasche 118 eine Selbsthemmung, da bei einem Herausziehen des Leiters 300 aus dem Klemmraum 119 die Klemmlasche 118 durch die Verschwenkmöglichkeit im Uhrzeigsinn verschwenkt wird und dadurch umso stärker gegen Leiter 300 gedrückt und verkeilt wird, wordurch ein ungewolltes Herausziehen des Leiters 300 besonders sicher verhindert werden kann.At the in 4 The embodiment shown, when a conductor 300 is inserted, the clamping lug 118 is further pivoted counterclockwise into the clamping space 119 in order to be able to insert the conductor 300 into the clamping space 119 . If the conductor 300 is inserted and connected, the pivotable arrangement of the clamping lug 118 enables self-locking, since when the conductor 300 is pulled out of the clamping space 119, the clamping lug 118 is pivoted clockwise due to the pivoting possibility and is thus pressed and wedged all the more strongly against the conductor 300 , As a result of which an unintentional pulling out of the conductor 300 can be prevented in a particularly reliable manner.

Zur Begrenzung der Schwenkbewegung der Klemmlasche 118 kann der Zugbügel 111 einen Begrenzungsanschlag aufweisen. Der Begrenzungsanschlag kann ein zu weites Einschwenken der Klemmlasche 118 in den Klemmraum 119 beim Anschließen des Leiters 300 verhindern. Der Begrenzungsanschlag kann unterhalb der Klemmlasche 118 an einem der Klemmschenkel 113, 114 angeordnet sein. Der Begrenzungsanschlag kann ebenfalls in den Klemmraum 119 hineinragen.To limit the pivoting movement of the clamping lug 118, the tension bracket 111 can have a limit stop. The limit stop can prevent the clamping lug 118 from pivoting too far into the clamping space 119 when the conductor 300 is connected. The limit stop can be arranged below the clamping lug 118 on one of the clamping legs 113, 114. The limit stop can also protrude into the clamping space 119 .
