Electric connection structure and connector thereof

Abstract

The invention relates to an electric connection structure and a connector thereof, and the electric connection structure comprises the connector and a connecting seat; the connector is provided with aconductive plugging part, and the conductive plugging part is used for being plugged into a conductive plugging hole in the connecting seat; the connector is fixedly provided with a shielding cover,and the connector is provided with a cylindrical shielding structure, wherein the cylindrical shielding structure is located at the radial outer side of the conductive plugging part and is coaxially arranged with the conductive plugging part; the cylindrical shielding structure and the main body part of the connector are integrally formed, an overhanging structure is formed on the main body part of the connector, and an annular space between the cylindrical shielding structure and the conductive plugging part forms an avoidance interval for avoiding the hole wall of the conductive plugging hole; the shielding cover is formed by a cylindrical shielding structure; the cylindrical shielding structure and the main body part of the connector are integrally formed, so a mounting space for assembling a screw is prevented from being reserved on the connector, the influence of the screw on the electric field of the electric connection structure is avoided, and the arrangement of the shielding cover in the electric connection structure is not limited by the screw connection structure.

Description

technical field [0001] The invention belongs to the field of electrical connection structures, and in particular relates to electrical connection structures and connectors thereof. Background technique [0002] The electrical connection structure is a widely used component in gas-insulated metal-enclosed switches (GIS) and gas-insulated metal-enclosed transmission lines (GIL). Its main function is to conduct rated current and instantaneous fault current in the main circuit. The quality of the electrical connection structure The quality directly affects the reliability of the equipment and the safe operation of the power grid. [0003] The electrical connection structure includes a connecting head and a connecting seat. Generally, one end of the connecting head is inserted into the corresponding end of the connecting seat when used, and the other end of the connecting head and the connecting seat is used to connect the corresponding conductive rod, so as to connect and conduc...
