Quick-connection type combined cable joint based on power equipment and combination method thereof

Abstract

The invention provides a quick-connection type combined cable joint based on power equipment and a combination method thereof, which belong to the technical field of cable joints, and aim to solve the problem that a fastening structure on an existing cable joint is very easy to loosen due to lack of an effective anti-loosening structure. The combined cable joint comprises a box body; two conductor connecting pieces are arranged on the bottom end face in the box body in a front-back symmetrical mode, and the two conductor connecting pieces are both of a square blocky structure. two through holes are symmetrically formed in the left end face and the right end face of the box body front and back, and two fastening mechanisms are arranged at the positions, located at the through holes, of the left end face and the right end face of the box body. Under the action that a right triangle limiting block at the head end of the square sliding column is in close contact with a circular bead limiting tooth on the outer peripheral surface of the threaded fastening cylinder, the threaded fastening cylinder cannot be loosened anticlockwise at the moment, and then the threaded fastening cylinder is not prone to loosening when the cable is subjected to external wind power and the like. And the connection firmness of the cable joint is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cable joints, and more specifically relates to a quick-connect combined cable joint based on electric equipment and a combination method thereof. Background technique [0002] Power equipment includes two categories: power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors wait. When electrical equipment transmits electrical energy, it needs to be transported through cables, and combined cable joints are generally used when connecting cable conductors. [0003] For example, application number: CN201810141055.2 A cable joint (16), including a housing (102), which has a channel (106), the channel is configured to hold the first signal conductor (406) of the first cable (14)...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a quick-connect combined cable joint based on power equipment and its combination method, to solve the problem that although the current combined cable joint can quickly connect the cable conductors, and can be connected by fastening The structure fastens the cable sheath on the box body, but the fastening structure on the cable joint lacks an effective anti-loosening structure, and the fastening structure is prone to loosening when the cable is subjected to external wind, etc., and the existing cable Although a desiccant can be placed inside the connector box to avoid moisture, mildew, and corrosion of the cable conductors inside the cable connector box, the desiccant needs to be replaced after it fails, and it is difficult for people to find the desiccant when repairing the inside of the cable connector box. The use of the situation, thereby reducing the reliability of the desiccant inside the cable joint box
