Abstract

Bei diesem Schutzleiteranschluß, insbesondere für Reihenklemmen, dessen Stromschienenstück (2) mit einem Abschnitt (6) an einer Tragschiene (1) festgesetzt wird, besteht die dafür vorgesehene gesonderte Klemmfeder (3) aus zwei federnd miteinander verbundenen Federschenkeln (8, 9), zwischen denen nach dem Aufrasten auf die Tragschiene ein Schenkel (5) der Tragschiene sowie der Abschnitt (6) des Stromschienenstückes (2) derart angeordnet liegen, daß sich der Abschnitt (6) an die zugeordnete Fläche des Schenkels (5) anlegt. Die Ausgestaltung ergibt einen sicheren Halt und kann die Sicherheitsfunktion auch in kritischen Betriebssituationen längerfristig gewährleisten.

Figure 00000001
In this protective conductor connection, in particular for terminal blocks, the busbar piece (2) of which is fixed with a section (6) to a mounting rail (1), the separate clamping spring (3) provided for this purpose consists of two resiliently connected spring legs (8, 9) between which, after snapping onto the mounting rail, a leg (5) of the mounting rail and the section (6) of the busbar piece (2) are arranged in such a way that section (6) lies against the assigned surface of the leg (5). The design provides a secure hold and can guarantee the safety function in the long term even in critical operating situations.
