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.

The invention discloses a touch finger component. By using the touch finger component, load consistency of each touch finger is provided, installation is simple and a production precision requirementis low. A technical scheme is characterized in that the touch finger component comprises a touch finger seat and several touch fingers; the touch finger seat is in a tube shape and an upper end portion of the touch finger seat is provided with several chutes along a circumferential direction; the chutes penetrate an outer wall of the touch finger seat along a radial direction; the touch fingers and the chutes form one-to-one correspondence; one end of each touch finger is provided with a connection portion and the connection portion is slidingly connected into each chute; the connection portion is provided with a rotation shaft; an inner wall of each chute is provided with a groove matching with the rotation shaft; an outer wall of the touch finger seat is provided with an annular groove connected to the chutes; a second annular spring abutting against each connection portion is arranged in the annular groove; an outer side wall of each touch finger is provided with at least one groove; at least one first annular spring is included; and the first annular spring is cooperated with the groove of each touch finger so that load consistency of each touch finger is guaranteed.
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...
