Round wire L-shaped locking connector and connection method thereof

Abstract

The invention discloses a round wire L-shaped locking connector and a connection method thereof. The round wire L-shaped locking connector comprises an electrically conductive connecting body, an input locking nut and an output locking nut; two ends of the connecting body are respectively provided with an input screw portion and an output screw portion which are perpendicular to each other; an input locking tube and an output locking tube are arranged on ends of the input screw portion and the output screw portion respectively; an input locking cone section and an output locking cone section are arranged in inner holes formed in outer ends of the input locking nut and the output locking nut; U-shaped openings are formed in the input locking tube and the output locking tube; the input locking nut and the output locking nut are connected to the input screw portion and the output screw portion respectively; and the input locking cone section and the output locking cone section are pressedon the input locking tube and the output locking tube respectively. The invention can quickly and vertically connect two round wires, can achieve reversing connection, can reduce the resistance, canprevent 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 an L-shaped 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 L-shaped wire connector includes a wire bolt crimping connection body and two wire pressing bolts. The connection body is processed with an input wire connection hole and a lateral compression bolt hole, a vertical output wire connection hole and a lateral compression bolt hole. [0004] Such as Figure 9-11 As shown, the connection body and bolts of the wire bolt crimping connector are generally made of stainless steel, the wire connection hole is horizontally processed with a threaded hole, and the compress...

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 wire connector has serious yield deformation after installation, the contact area between the wire and the connector is small, and The difference between the linear expansion coefficient of the wire connector and the wire is relatively large. After a long period of operation, after many cycles of cooling and heating, the crimping part of the wire bolt continues to undergo plastic deformation, resulting in loosening of the gap, and the entry of air, etc. makes the connection body compressed. The junction surface is oxidized, which increases the contact resistance of the conductor connector and causes heat failure
