Connecting structure of electric conducting rod and electric connecting device

Abstract

The invention relates to a connecting structure of an electric conducting rod and an electric connecting device. The connecting structure comprises an electric conducting rod and a connecting head, wherein the connecting head is fixed at the front end of the electric conducting rod, the front end of the electric conducting rod or the rear end of the connecting head is provided with a pressure welding deformation section, the pressure welding deformation section is provided with an insertion cavity, the rear end of the connecting head or the front end of the electric conducting rod is providedwith a corresponding insertion section, the insertion section is used for being inserted into the insertion cavity of the pressure welding deformation section, a pressure welding deformation part is arranged on the side wall of the pressure welding deformation section, the pressure welding deformation part deforms towards the radial inner side of the pressure welding deformation section so as to be fixed on the insertion section in a pressure welding manner, and the connecting head and the electric conducting rod are inserted into the insertion cavity of the pressure welding deformation section through the insertion section. According to the invention, the pressure welding deformation section deforms inwards in the radial direction so as to be fixed to the insertion section in a pressure welding manner, so that the effective contact and fixed connection between the connecting head and the electric conducting rod are achieved, the mode that the connecting head and the conducting rod arewelded and fixed to a bolt for fixed connection is avoided, use of standard member is reduced, and the production cost of the electric connection device is reduced.

Description

Technical field [0001] The invention belongs to the field of electrical connection devices, and particularly 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 switch (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, and the quality of the electrical connection device The quality directly affects the reliability of the equipment and the safe operation of the power grid. [0003] At present, the contact base, the contact finger base and the 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 welding seam needs to be polished, which causes welding The efficiency is low, and...
