Description

TECHNICAL FIELD The present invention relates to the technical field of harness terminal connections, and more particularly to a device and method of operation for fixed connection of power electronic conductors and terminals.

In electrical installations, terminals mainly refer to terminals, also called terminal blocks. The types of terminals are classified into single-hole, double-hole, receptacle, hook type, and the like. The material of the terminals can be divided into silver-plated copper, galvanized copper, copper, aluminum, iron and so on. Terminals are often used to connect wires, allowing stronger connections between wires and appliances and between wires. A cable lug is a common kind of terminal, which consists of a cylindrical part and a gasket part, and is mainly used to connect multiple conductors of ^4mm2 or more. The conventional method of connecting a conductor wire and a cable lug is for an operator to manually remove the insulation layer of the conductor wire, insert it into the cable lug, and crimp the cable lug with crimping pliers. Due to the ever-increasing quality requirements for wire connection of electrical equipment, manual operation cannot meet the unified requirements and standards, and manual operation has high labor intensity and low production efficiency.

A wire and cable lug crimping device disclosed in CN201720615937.9 includes a frame, a cylinder, a crimping upper tire, a crimping lower tire, a solenoid valve and a control switch, wherein the crimping device comprises a cylinder Due to the force method in which the pressure provided by the exercise replaces human power, it has the advantages of high export pressure, high efficiency, simple structure, robustness and durability, and relatively easy maintenance. vinegar. Although the crimping device can increase processing efficiency compared to manual connection of cable lugs and conductors, when the crimping device or other similar devices in the prior art are used to actually connect the lugs and conductors, There are still the following problems: (1) After the end of the conductor is inserted into the cylindrical part of the cable lug, there is still a large space in the radial direction of the cylindrical part, and the end of the conductor can be removed by simply crimping the cylindrical part. It cannot be fixed firmly and the end of the conductor tends to fall out of the cable lug during use. (2) When connecting two conductors using a lug, after fixing the end of one conductor in the cylindrical part, manually pass the end of the other conductor through the center hole of the gasket part. If necessary, then tighten the wires. The operation of passing the conductor wire through the terminal gasket requires a high level of operator experience, and the processing efficiency is low.
