Description

Technical Field

[0001] The present application relates to the technical field of power equipment components, and in particular to a pluggable busbar connector. Background Art

[0002] Busbars are divided into hard busbars (rectangular busbars, trough busbars, tubular busbars), soft busbars (aluminum stranded wires, copper stranded wires, expanded diameter hollow conductors) and closed busbars. Closed busbars are referred to as bus ducts. Busbar connectors are electrical connectors used to connect electrical bus ducts. Electrical bus ducts are long strip structures made of conductive materials used to transmit current and electrical energy. They are usually used in power distribution systems, electrical control cabinets and electrical equipment. The main function of busbar connectors is to transmit electrical energy, transporting electricity from power stations to substations, and then from substations to various distribution systems. Busbar connectors connect different busbars to each other to form a large power transmission system. Through the connection of busbar connectors, electricity can flow freely between the busbars to ensure the normal operation of the power system.

[0003] However, with existing busbar connectors, when installing the upper busbar and the lower busbar in the connector, the busbar needs to be in close contact with the partition in the connector. Most of the methods are to tighten the bolts to make the busbar in contact with the partition. The bolts are manually tightened to make the partition clamp the upper and lower busbars. Improper force will cause the bolts to loosen or not be tightened, so that the partition in the connector cannot clamp the upper and lower busbars, causing the connection to loosen. Therefore, a new solution is needed to solve this problem. Utility Model Content

When the upper busbar and the lower busbar are installed in the connector, the busbar needs to be in contact with the partition in the connector, and most of the time, the partition is tightened by bolts to clamp the upper and lower busbars. Improper force application may cause the bolts to loosen or not be tightened, so that the partition in the connector cannot clamp the upper and lower busbars, resulting in loose connection.
