High-stability h-shaped clamp and crimping method for electrical connection of non-tension wires

Abstract

The invention provides a high-stability H-type cable clamp. The cable clamp comprises a cable clamp base body; sickle-shaped first cover sheets are connected with upper side wings formed by cable channels in the left and right sides of the cable clamp base body respectively; the lower side wings formed by the cable channels in the left and right sides of the cable clamp base body are bent inwardly; two sickle-shaped second cover sheets extending towards the left and right sides are further arranged at the bottom of the cable clamp base body; sickle-shaped accommodating spaces are formed between the second cover sheets and the lower side wings; and when the cable clamp is used for crimping, the first cover sheets extend into the sickle-shaped accommodating spaces. The high-stability H-type cable clamp provided by the invention is simple in structure; compared with the existing cable clamp, the bonding area in the crimping part is greatly enlarged, so that the binding force in the crimping part is effectively reinforced and the connecting strength is enhanced. The invention also provides an electrical connecting and crimping method for non-tension lines; the H-type cable clamp can be fully utilized without causing strand-separating of wires; the wire is fully and tightly covered with the crimped H-type cable clamp, so that the covered wire is low in fault rate and high in power supply reliability.

Description

technical field [0001] The invention relates to the technical field of wire connection, in particular to a high-stability H-shaped wire clip and a non-tension wire electrical connection crimping method. Background technique [0002] Wire clamp (or called connector) is a commonly used power fittings, widely used in overhead high-voltage lines and low-voltage power line pole jumpers, branch lines, lead wires of various electrical equipment, household wires, house wires and other wires The crimping of underground low-voltage aluminum power lines in the hand hole, the crimping of connection lines, branch lines, lead-in lines and wires entering the house, and the non-tension line segments of low-voltage aluminum power lines in the house, connection lines, branch lines, and various electrical equipment Crimping of low-voltage side leads, etc. [0003] There is an H-shaped wire clip, which includes a wire clip base body with wire grooves on the left and right sides and sickle-shap...

AI Technical Summary

Problems solved by technology

Although the wire clip with the above structure has the advantages of convenient use and good current conduction effect, after a period of use, the crimping part is easy to expand and the stability is poor, and there are still certain potential safety hazards

[0004] In addition, most of the crimping processes for the electrical connection of non-tension wires through H-type clamps are not standardized. The crimping operation can easily cause loose strands of wires, lax coating, and unstable connection, which fails to fully tighten the H-type clamps. The use, but also the efficiency of the heart
