This represents the Tension position of the clamping spring, in which the device to the Is delivered to customers.

Die Montage des Leiters 20 an die Anschlussklemme 10 erfolgt dadurch, dass das abisolierte Ende 21 des Leiters 20, das im dargestellten Fall der Fig. 7 aus einem Drahtbündel besteht, in die Ausnehmung 12 und durch die Fensteröffnung 5 hindurch geschoben wird. Danach wird die Klemmfeder 1 losgelassen und der Rand der Fensteröffnung 5 drängt die Leiterdrähte 21 gegen die Innenseite des Wandabschnittes 14, hauptsächlich im Bereich der eintrittsseitigen Queröffnung 13. Die einzelnen Drähte 21 verteilen sich entlang der zylindrischen Wandinnenseite der Wand 14 und werden gegen diese gepresst, so dass ein guter Stromübergang zwischen dem Leiter 20 und dem Kontaktteil 10 zu erwarten ist.The conductor 20 is mounted on the connecting terminal 10 in that the stripped end 21 of the conductor 20, which in shown case of FIG. 7 consists of a wire bundle, into the recess 12 and through the window opening 5 is pushed. Then the clamping spring 1 is released and the edge of the window opening 5 urges the conductor wires 21 against the inside of the wall section 14, mainly in Area of the transverse opening 13 on the inlet side. The individual Wires 21 are distributed along the cylindrical Inside of the wall 14 and are pressed against it, so that a good current transfer between the conductor 20 and the contact part 10 is to be expected.

Die Fig. 5 bis 7 zeigen eine zweite Ausführungsform des Kontaktbetätigers 40. Dieser besteht aus einem Rasthebel, der über eine Raststelle 45 geschwenkt werden kann, um die Klemmfeder 1 in ihrer Vorbereitungsstellung zur Leiteraufnahme zu halten, wie in Fig. 6 dargestellt. In dieser Stellung fluchten die Öffnung 5 im Klemmschenkel 2 und die Ausnehmung 12 im Kontaktelement 10 zueinander, so dass ein Leiter 20 eingeführt und nach Rückschwenken des Hebels 40 geklemmt werden kann, wie Fig. 7 zeigt.5 to 7 show a second embodiment of the Contact actuator 40. This consists of a locking lever, the can be pivoted about a rest stop 45 to the Clamping spring 1 in its preparation position To hold the conductor holder as shown in Fig. 6. In this position, the opening 5 in the clamping leg 2 and the recess 12 in the contact element 10 to each other, so that a conductor 20 is inserted and after pivoting the lever 40 can be clamped, as Fig. 7 shows.

Während die Verwendung von Kontaktbetätigern 40 bevorzugt wird, ist es auch möglich, solche Kontaktbetätiger fortzulassen und die Klemmfedern bei der Montage der Leiter 20 durch jeweils einen länglichen Gegenstand, beispielsweise einen Schraubendreher, zusammenzudrücken, um die Fluchtung zwischen der Fensteröffnung 5 und der Ausnehmung 12 herbeizuführen.While the use of contact actuators 40 is preferred it is also possible to use such contact actuators omit and the clamping springs when assembling the ladder 20 by an elongated object, for example a screwdriver to squeeze the alignment between the window opening 5 and the recess 12 bring about.
