An adaptive movable conductive connection mechanism

Abstract

The invention discloses an adaptive movable conductive connecting mechanism comprising static contact seats, two conductive clamp pieces, and a clamp spring assembly; the static contact seats comprise a conductive seat and a guide seat; the conductive seat is fixed on the guide seat; the guide seat is arranged on a support insulator; two sides of the conductive seat are respectively provided with an inner taper hole; the two conductive clamp pieces are respectively arranged on two sides of the static contact seat; the upper portions of the two conductive clamp pieces are respectively shafted by a conductive hemisphere; the two conductive hemispheres are respectively embedded into the inner taper holes for conductive contacts; the clamp spring assembly is arranged in a mount hole of the guide seat; two ends of the clamp spring assembly extend outside the two sides of the guide seat, and are respectively connected with the two conductive clamp pieces. The adaptive movable conductive connecting mechanism can solve the electric connection problems of the movable and static contacts of a rotary type knife switch.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an adaptive movable conductive connection mechanism on a knife switch in a switch cabinet. Background technique [0002] The knife switch has the characteristics of simple structure and reliable operation. It is widely used in complete switchgear and independent switching elements in the power switch industry. In the current knife switch, in order to ensure a good conductive contact between the moving knife and the static contact, according to the size of the current flow capacity, multi-contacts or multi-contact fingers are usually used, but due to the small contact area of ​​a single contact Small, limited flow capacity, and in the structure of multiple contacts (contact fingers), affected by the processing and installation accuracy of parts, usually only part of the contact fingers can be reliably contacted, which affects the overall flow capacity of the switch.
