Electric connecting assembly

Abstract

The invention discloses an electric connecting assembly, and aims to provide an electric connecting assembly which is uniform in load on each contact finger, simple in installation and relatively lowin production accuracy requirement. Through key points of the technical scheme, the electric connecting assembly comprises a contact finger seat and a plurality of contact fingers; the contact fingerseat is tubular, and an annular arc-shaped block is arranged at the upper end of the contact finger seat; each contact finger is provided with an annular arc-shaped groove which is matched with the annular arc-shaped block and is in sliding connection with the annular arc-shaped block; a groove is formed in the outer side wall of the contact finger seat; the groove is internally provided with a second annular spring; an abutting piece abutting against the second annular spring is extended at the lower end of each contact finger; and at least one annular groove is formed in the outer side wallof each contact finger. The electric connecting assembly also comprises a first annular spring abutting against the annular groove; the annular arc-shaped block is matched with the annular arc-shapedgrooves and is in sliding connection with the annular arc-shaped grooves to form a slidable structure, and a reliable elastic structure is formed through interaction of the second annular spring and the first annular spring, so that the uniformity of load on each contact finger is guaranteed.

Description

technical field [0001] The invention relates to an electrical connection assembly, more specifically to an electrical connection device for 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.
