Connection structure between conductive rod and electrical connection device

Abstract

The invention relates to a connection structure between a conductive rod and an electrical connection device, comprising a conductive rod and a connecting head; The deformed section has an insertion cavity; the rear end of the connector or the front end of the conductive rod is provided with a corresponding inserting section, which is used to be inserted into the inserting cavity of the deformed crimping section; on the side wall of the deformed crimping section There is a crimping deformation part, and the crimping deformation part is deformed to the radial inner side of the crimping deformation section to be crimped and fixed on the insertion section; the connection head and the conductive rod are inserted into the crimping section through the insertion section In the insertion cavity of the deformed section, the deformed section is deformed radially inwards to be crimped and fixed to the inserted section, so as to realize effective contact and fixed connection between the connector and the conductive rod, avoiding the need for welding and fixing with bolts The connection method reduces the use of standard parts and reduces the production cost of the electrical connection device.

Description

technical field [0001] The invention belongs to the field of electrical connection devices, and in particular relates to a connection structure between a conductive rod and an electrical connection device. Background technique [0002] Electrical connection devices are widely used components in gas-insulated metal-enclosed switches (GIS) and gas-insulated metal-enclosed transmission lines (GIL). The main function is to conduct rated current and instantaneous fault current in the main circuit. The quality of electrical connection devices The quality directly affects the reliability of the equipment and the safe operation of the power grid. [0003] At present, the contact seat, contact finger seat and conductive rod in the electrical connection device are connected together by welding or bolts; the welding method has the following problems. In order to ensure the electric field needs, the weld seam needs to be polished, which causes welding The efficiency is low, and the wel...
