Abstract

The invention relates to a conducting electric device for electric switch equipment. The conducting connecting device is characterized in that two functions of electric field optimization and current carrying of a contact seat in the prior art are separated, the conducting connecting device is divided into a shielding cover used for electric field optimization and a contact seat used for being in charge of current carrying, a touch finger installing groove is positioned on the outer peripheral wall of the contact seat, and the outer peripheral surface of the guide end of an insulation guide element is exposed out from the outer peripheral surface of the contact seat to be in contact with the inner wall surface of a conducting tube, so the blind hole structure in the contact seat in the prior art is removed, the appearance size and the weight of the contact seat are reduced, in addition, the processing difficulty of the contact seat is lowered, the manufacture cost of the contact seat is reduced, and further, the problems of large own appearance size, heavy weight and high manufacture cost of the contact seat in the prior part are solved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a conductive connection device for electrical switching equipment. Background technique [0002] At present, in gas-insulated metal-enclosed switchgear, there are mainly two types of contact between the bus bar and the electrical connection: crimping type and plug-in type. Among them, the plug-in type mostly uses contact seats with spring contacts or strap contacts, or in A spring contact finger or a watch strap contact finger is installed on the conductive tube. For example, the Chinese invention patent with application number 200820228958.6 discloses a conductive connection device for gas-insulated metal-enclosed switchgear. and the blind end of the blind hole is screwed to not only fix the contact seat on the connecting insert of the insulating basin, but also extend into the inner hole of the conductive tube to ensure the coaxiality of the conductive tube and th...
