Circuit-breaker pole part with a flexible conductor for connecting a movable electrical contact

摘要

The invention relates to a pole part of a circuit-breaker arrangement comprising an insulation housing (1) for accommodating a vacuum interrupter (8) containing a pair of corresponding electrical switching contacts (4, 7), wherein a fixed upper electrical contact (7) is connected to an upper electrical terminal (2) molded or assembled in the insulation housing (1) and a movable lower electrical contact (4) is connected to the insulating housing by a support plate of the insulation housing (1) via a flexible conductor (6) comprising a first end (11) for attaching the flexible conductor (6) to the lower electrical terminal (3) and a second end (13) for attaching the flexible conductor (6) to the movable lower electrical contact (4), wherein the second end (13) of the flexible conductor (6) is provided with an inside thread (14) which is screwed to an outside thread (15) arranged on the distal end of the movable lower electrical contact (4).
