Die Klemmeinrichtung kann als Rahmenklemme ausgeführt sein, die innen ein feststehendes Anschlusselement und eine bewegbare Anschlussklemme aufweist. Das Bewegen der Anschlussklemme in Richtung des Anschlusselements kann schraubenartig durch Verdrehen erfolgen, wobei das Hauptleiterende zwischen dem Anschlusselement und der Anschlussklemme jeweils festgeklemmt wird. Weiter ist es bekannt, zur Versorgung externer Geräte einen Stromabgriff in Form eines Hilfsleiteranschlusses vorzusehen. Üblicherweise wird der Hilfsleiteranschluss zusätzlich zu dem Hauptlei- terende in die Klemmeinrichtung eingesteckt und mit diesem zusammen festgeklemmt. Hilfsleiteranschluss und Hauptleiterende werden auf diese Weise elektrisch miteinander verbunden. Nachteilig ist dabei, dass die bekannten Hilfsleiteran- schlüsse nicht für alle Baugrößen von Kompaktleistungsschal- tern geeignet sind.It is known to use compact power switches for connecting and disconnecting a plurality of current-carrying main conductors, each having a clamping device for connecting a main conductor, in each of which a main line terende is inserted. The clamping device can be designed as a frame clamp, which has a fixed connection element inside and a movable connection terminal. The moving of the terminal in the direction of the connecting element can be carried out helically by twisting, wherein the main conductor end between the connecting element and the terminal is clamped in each case.

Usually, the auxiliary conductor connection is inserted in addition to the main conductor end into the clamping device and clamped together with this. Auxiliary conductor terminal and main conductor end are electrically connected to each other in this way. The disadvantage here is that the known auxiliary conductor connections are not suitable for all sizes of compact circuit breakers.

Die geringfügigen Ver- änderungen sind einmal eine Verlängerung des Klemmteils und zum anderen eine Verbreiterung der Verdrehsicherung. Zusätzlich kann durch Veränderung der Breite des Anschlussendes die Flexibilität bei der Auswahl der Anschlussvarianten erhöht werden .Clamping devices regardless of the size of the circuit breaker suitable and offers the possibility to adapt by a slight change in the auxiliary conductor connection, this to the appropriate size. The minor changes are once an extension of the clamping part and on the other hand, a widening of the anti-rotation.

Kostengünstig ist es, wenn der Hilfsleiteranschluss aus einem Blech gebildet ist. Einfacherweise weist das Blech parallel zueinander verlaufende Biegekanten auf.It is cost-effective if the auxiliary conductor connection is formed from a metal sheet. The sheet metal simply has mutually parallel bending edges.
Um ein Verdrehen des Hilfsleiteranschlusses auf einfache Weise zu verhindern, wird vorgeschlagen, dass die Verdrehsicherung aus einem quer zum Klemmende gebogenen Abschnitt gebildet ist.In order to prevent twisting of the auxiliary conductor connection in a simple manner, it is proposed that the anti-rotation device is formed from a section bent transversely to the terminal end.

Figur 4 zeigt eine Klemmeinrichtung 1 in Form einer Rahmenklemme, die an einem nicht gezeigten Kompaktleistungsschalter zum Unterbrechen und Verbinden von Hauptleitern 2 angeordnet ist. Die Hauptleiter 2 werden mittels der Klemmeinrichtungen 1 am Leistungsschalter angeschlossen, die jeweils einen Rahmen Ia aufweisen, in dem auf einer Seite ein plattenförmiges Anschlusselement 3 fest angeordnet ist. Dem Anschlusselement 3 gegenüberliegend ist eine Anschlussklemme 4 vorgesehen, die mittels eines Drehbolzens 5 in Richtung des Anschlusselementes 3 bewegbar ist. Der Drehbolzen 5 weist ein Außengewinde auf, dessen zugehöriges Innengewinde sich in einer Durchgangsöffnung des Rahmens Ia befindet und trägt an seinem im Innern des Klemmrahmens Ia befindlichen Ende die Anschluss- klemme 4. Die Klemmeinrichtung 1 in Figur 4 ist in geöffnetem Zustand gezeigt, wobei ein Ende 2a und ein Hilfsleiteranschluss 6 mit seinem Klemmende 7 eingesteckt sind. Dabei befindet sich das Hauptleiterende 2a zwischen dem Anschlusselement 3 und dem Klemmende 7, das sich wiederum zwischen dem Hauptleiterende 2a und der Anschlussklemme 4 befindet. Das Festklemmen des Hauptleiterendes 2a und des Klemmendes 7 erfolgt durch Verdrehen des Drehbolzens 5, wobei sich die Anschlussklemme 4 in Richtung Anschlusselement 3 bewegt, bis es zum Festklemmen von Hauptleiterende 2a und Klemmende 7 kommt.FIG. 4 shows a clamping device 1 in the form of a frame terminal, which is arranged on a molded case circuit breaker, not shown, for interrupting and connecting main conductors 2. The main conductors 2 are connected by means of the clamping devices 1 on the circuit breaker, each having a frame Ia, in which on one side a plate-shaped connection element 3 is fixedly arranged. The connecting element 3 opposite a terminal 4 is provided, which is movable by means of a pivot pin 5 in the direction of the connecting element 3. The pivot pin 5 has an external thread, the associated internal thread is located in a through hole of the frame Ia and carries at its located in the interior of the clamping frame Ia end of the terminal 4. The clamping device 1 in Figure 4 is shown in the open state, wherein a End 2a and an auxiliary conductor terminal 6 are inserted with its terminal end 7. In this case, the main conductor end 2a is located between the connection element 3 and the clamping end 7, which in turn between the Main conductor end 2a and the terminal 4 is located. The clamping of the main conductor end 2a and the clamping end 7 is carried out by turning the pivot pin 5, wherein the terminal 4 moves in the direction of connection element 3 until it comes to clamping of main conductor end 2a and terminal end 7.
In Figur 1 ist eine räumliche Darstellung des Hilfsleiteran- schlusses 6 gezeigt, an dessen unterem Ende (bezogen auf Figur 1) das flache Klemmende 7 ausgebildet ist, das aus einem Blech durch Biegen mit parallel zueinander verlaufenden Biegekanten, z.B. 12, 13, gebildet ist. So kann der Hilfsleiter- anschluss 6 als erstem Arbeitsschritt bei der Herstellung aus einem Blech ausgestanzt sein. Wie Figur 1 zeigt, schließt sich an das Klemmende 7 ein quer zu dem Klemmende 7 verlau- fender Bereich (Verdrehsicherung 8) an, der ein Verdrehen innerhalb der Klemmeinrichtung 1 (Figur 1) verhindert. Senkrecht dazu verläuft ein sich anschließender Anschlussbereich 9 mit einer Durchgangsöffnung 10 für ein Befestigungselement (nicht gezeigt), z.B. in Form einer Schraube mit Dachscheibe. An den Anschlussbereich 9 schließt sich ein Anschlussende 11 an, das im Wesentlichen parallel zum Anschlussbereich 9 verläuft (gebildet durch zwei Biegekanten 12, 13) . Das Anschlussende ist so ausgebildet, dass sich ein Steckelement 14 (s. Figur 2) in Form eines Flachsteckers oder eines Kabel- schuhs zur Erstellung einer elektrischen Verbindung mit dem Hauptleiter 2 aufschieben lässt. Wie die Figur 1 zeigt, ist die Verdrehsicherung 8 hier mit seinen seitlichen Enden 15 zum Klemmende 7 hin gebogen. Das flache Klemmende 7 selbst ist quer zur Einsteckrichtung mit einer Krümmung versehen.FIG. 1 shows a three-dimensional representation of the auxiliary conductor connection 6, at the lower end of which (with reference to FIG. 1) the flat clamping end 7 is formed, which is formed from a metal sheet by bending with mutually parallel bending edges, e.g. 12, 13, is formed. Thus, the auxiliary conductor connection 6 may be punched out of a metal sheet as the first working step during manufacture. As shown in FIG. 1, the clamping end 7 is adjoined by a region (anti-twist device 8) extending transversely to the clamping end 7, which prevents rotation within the clamping device 1 (FIG. 1). Perpendicular to this, a subsequent terminal region 9 extends with a through opening 10 for a fastener (not shown), e.g. in the form of a screw with roof glass. Adjoining the connection region 9 is a connection end 11, which runs essentially parallel to the connection region 9 (formed by two bending edges 12, 13). The connection end is designed in such a way that a plug-in element 14 (see FIG. 2) in the form of a tab or a cable shoe can be pushed on to make an electrical connection to the main conductor 2. As Figure 1 shows, the anti-rotation 8 is here bent with its lateral ends 15 to the terminal end 7 out. The flat terminal end 7 itself is provided transversely to the insertion direction with a curvature.
