Abstract
A switchgear apparatus comprises a vacuum cartridge one contact of which is fixedly secured to a metal rod protruding out from the cartridge. A flexible metallic electrical connector designed to electrically connect the rod to a busbar is provided, at one of its ends, with a bored hole in which one end of the rod is inserted. The joint between the flexible electrical connector and the rod is achieved by means of a braze implementing a metallic filler compound having a low melting temperature, so as not to damage the cartridge when the brazing operation is performed.
