Round wire multi-branch locking connector and connection method thereof

Abstract

The invention discloses a round wire multi-branch locking connector and a connection method thereof. The round wire multi-branch locking connector comprises an electrically conductive connecting body,an input locking nut and output locking nuts; the connecting body are provided with an input screw portion and a plurality of output screw portions; an input locking tube and an output locking tube are arranged on ends of the input screw portion and each output screw portion respectively; an input locking cone section and output locking cone sections are arranged in inner holes formed in outer ends of the input locking nut and the output locking nuts; U-shaped openings are formed in the input locking tube and the output locking tubes; the input locking nut and the output locking nuts are connected to the input screw portion and the output screw portions respectively; and the input locking cone section and the output locking cone sections are pressed on the input locking tube and the output locking tubes respectively. The invention can quickly and vertically connect multi-branch round wires, can reduce the contact resistance, can prevent gaps, loosening and oxidation of a joint conductor contact surface after the hot and cold cycle of the connector, and can improve the connection reliability of the joint.

Description

technical field [0001] The invention belongs to the technical field of power connection equipment, and in particular relates to a multi-branch locking connector for round wires and a connection method thereof. Background technique [0002] In the previous connection of round wires, wire bolt crimp connectors are usually used for connection. This type of connector has a simple structure, is easy to install, and does not require high quality operators. [0003] The existing multi-branch bolt crimping connector for round wires comprises a wire bolt crimping connection body and a plurality of wire crimping bolts. The connection body is processed with an input wire connection hole and a lateral compression bolt hole, a plurality of output wire connection holes and a lateral compression bolt hole. [0004] Such as Figure 10-12 As shown, the connection body and bolts of the wire bolt crimping connector are generally made of stainless steel, the wire connection hole is horizontall...

AI Technical Summary

Problems solved by technology

[0005] Although the wire connection of the wire bolt crimping connector is simple and easy to implement, due to the difference between the material of the connector and the wire, the lead connector has serious yield deformation after installation, the contact area between the wire and the connector is small, and The linear expansion coefficients of the connecting body of the wire connector, the crimping bolt and the wire are relatively different. After a long period of operation, after many cycles of cold and heat, the crimping part of the wire bolt continues to undergo plastic deformation, resulting in loosening of the gap and air Waiting for entry will oxidize the crimping surface of the connector, increase the contact resistance of the conductor connector, and cause heat failure
