Problems solved by technology

For example, the volume of the plum contact is too large, the installation is difficult, and it is not conducive to the miniaturization of the product. The installation of the spring contact and the strap contact finger is too small, the carrying capacity is too small, etc. It is complex and requires high installation requirements
Therefore, the contact finger connectors currently used have defects such as high installation accuracy, complex structure, and insufficient flow capacity in contact finger assembly.

Abstract

The invention provides a hoop contact finger connector. The hoop contact finger connector comprises more than two hoop contact pieces and more than two connecting springs, each hoop contact piece comprises an arc-shaped contact piece and a base designed at the tail part of the contact piece; more than two fixing structures are designed in the base; the connecting springs are made of elastic metalmaterials; connectors are designed at two ends of the connecting springs respectively; the hoop contact pieces are divided into two groups; the contact piece ends of the two groups of hoop contact pieces are mutually inserted; and the base of each hoop contact piece in the same group is connected with the base of the adjacent hoop contact piece in the opposite group through the more than one connecting spring respectively. The connector is more compact in structure, greatly reduces requirements on machining errors of matched parts and installation positions of different parts during use, improves the connection reliability of electric connection, and is smaller in size and higher in product through-flow capacity under the same through-flow capacity.

Description

technical field [0001] The invention relates to a high-voltage switchgear, in particular to a connection contact finger for connecting a conductive circuit in a circuit breaker, an isolating switch and a busbar system. Background technique [0002] Under modern technology, the requirements for the connection of high-voltage switchgear are large load, small size, large deviation allowed for installation, and long service life. Now in the switchgear, the common ways to connect the parts with relative movement and to connect the conductive circuit are plum blossom contacts, spring contacts, watch strap contacts and other connection methods, and these connection methods do not have the above-mentioned switch connection. All feature requests. For example, the volume of the plum contact is too large, the installation is difficult, and it is not conducive to the miniaturization of the product. The installation of the spring contact and the strap contact finger is too small, the ca...
