a tactile component

Abstract

The invention discloses a contact finger assembly, which aims to provide consistent load on each contact finger, is easy to install, and requires low production precision. Finger, the contact finger seat is tubular and the upper end of the contact finger seat is provided with a number of chutes along the circumference, and the chute runs through the outer wall of the contact finger seat in the radial direction, and the contact fingers correspond to the chute one by one. One end of the contact finger is provided with a connecting part and the connecting part is slidably connected in the chute, the connecting part is provided with a rotating shaft, the inner wall of the chute is provided with a groove matching the rotating shaft, and the contact finger is The outer wall of the seat is provided with an annular groove communicating with the chute, and the second annular spring that conflicts with each connecting part is provided in the annular groove, and the outer wall of the contact finger is provided with at least one groove, and at least one first An annular spring, the first annular spring cooperates with the groove on each contact finger to ensure the consistency of the load on each contact finger.

Description

technical field [0001] The invention relates to a contact finger assembly, more specifically to an electrical connection device 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. Another kind of pl...

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.
