Embodiment Construction

[0020] figure 1 An exemplary embodiment of a switching pole 1 according to the invention is shown in a side cross-sectional view. The switching pole 1 shown has a housing 2 of insulating material made of cast resin, which is dimensionally stable and in which an input connection 3 is cast at its upper end and an output is cast in the middle. Connector 4. A vacuum interrupter tube 5 is fastened to the upper inlet connection piece 3 by means of a screw connection 6 which is clamped through a through-hole provided in the inlet connection piece 3 and threaded with its free end in a form-fitting manner. Link to each other with static contact bar 7. The static contact rod 7 fastens the end cover 8 of the vacuum switch tube 5 , and the end cover together with the insulating ceramic shell 9 and the lower end cover 10 forms a vacuum switching cavity.

[0021] A static contact not shown in the figure is arranged on the free end of the static contact rod protruding into the switch cavi...

Abstract

The invention relates to a circuit breaker pole (1) for interrupting the electric current, which is insulated by a solid material and has a dimensionally stable and electrically non-conducting insulating material housing (2), a switching tube (5) fastened in the insulating material housing (2) and having a stationary fixed contact and a movable mobile contact, an input connection piece (3) electrically connected to the fixed contact and contactable from outside, and an output connection piece (4) connected to the mobile contact via a mobile contact connection (12), said output connection piece being linked with the insulating material housing (2) in a fixed manner and having a contact surface that can be contacted from outside, whereby the insulating material housing (2) has an opening for inducing a driving motion into the mobile contact. The aim of the invention is to provide a circuit breaker pole of the aforementioned kind which is inexpensive and easy to install. For this purpose, the mobile contact connection (12) is fixed to the output connection piece (4) by connecting means (17) which act upon the contact surface.

Description

technical field [0001] The invention relates to a solid-insulated switching pole (Schalterpol) for interrupting current, which has a dimensionally stable and non-conductive insulating material housing, a fixed fixed contact with a fixed position in the insulating material housing A switch tube with a movable movable contact, an input connection piece electrically connected to the fixed contact and accessible from the outside, and an output connection piece connected to the moving contact by means of a moving contact connection structure, the The output connector is fixedly connected to the insulating material housing and has an externally accessible contact surface, wherein the insulating housing is provided with an opening for introducing a drive movement to the movable contact. [0002] In addition, the invention relates to a method for switching on a moving contact connection of a solid-insulated switch pole with a dimensionally stable and non-conductive insulating material...
