Electric connecting assembly

Abstract

The invention discloses an electric connecting assembly, and aims to provide the electric connecting assembly with load consistency on each contact finger, simple installation and relatively low production precision requirement. The technical scheme key point is that the electric connecting assembly comprises a contact finger base and a plurality of contact fingers; the contact finger base is tubular, and a plurality of sliding grooves are formed in the upper end part of the contact finger base in the circumferential direction; the contact fingers and the sliding grooves are in one-to-one correspondence; a connecting part is arranged at one end of each contact finger, and the connecting part is glidingly connected in the corresponding sliding groove; a first V-shaped groove is formed in the side wall, far from the contact finger base axis, of each connecting part; a second V-shaped groove is formed in the side wall, opposite to the first V-shaped groove, of the each sliding groove; a second annular spring props against between the first V-shaped groove and the second V-shaped groove; at least one groove is formed in the outer side wall of each contact finger; and the electric connecting assembly also comprises at least one first annular spring which is connected with the groove in a prop-against manner, so that load consistency on each contact finger is ensured.

Description

technical field [0001] The present invention relates to an electrical connection assembly, more specifically to an electrical connection assembly of a gas-insulated metal-enclosed switch (GIS). Background technique [0002] The main function of the electrical connection device of the gas-insulated metal-enclosed switch (GIS) is to conduct the rated current and the instantaneous fault current in the main circuit. It has high requirements on the electrical and mechanical properties of the electrical connection, and its quality is good. Failure directly affects the reliability of GIS and the safe operation of the power grid. [0003] At present, the electrical connectors in domestic GIS equipment are usually connected by plum blossom contacts or strap contacts. Although the connection method of the contact finger structure of the strap is low in cost, it has high requirements on the matching clearance of the connection, and it is difficult to assemble in actual construction. ...

Problems solved by technology

Although the connection method of the contact finger structure of the watch strap is low in cost, it has high requirements for the matching clearance of the connection, and it is difficult to assemble in actual construction

Another kind of plum blossom contact finger structure has slightly lower requirements on the fit clearance of the connection, but it cannot guarantee the consistency of the load on each contact finger, and the installation is difficult, and the production accuracy is high.
