Special cable adapter device for electrical engineering

Abstract

The invention provides a special cable adapter device for electric appliance engineering, relates to the field of cable connecting pieces, and solves problems that a fastening bolt is easy to loosen after an adapter on mobile joint equipment is utilized for a period of time and a rain-proof structure and the connection strength cannot be organically combined. The special cable adapter device for electrical engineering comprises a socket main body and a rectangular plug, wherein a waterproof sleeve is welded on the socket main body. On one hand, the sleeve main body is drawn outwards and rotated, so a bolt rod and a fastening connecting seat can be screwed through threads, the sleeve main body can be locked by loosening the sleeve main body through an elastic bayonet lock, on the other hand, due to arrangement of the elastic bayonet lock, when the position is narrow, the sleeve main body is inconvenient to draw, the sleeve main body can be directly made to rotate, a bolt rod can be screwed down and the sleeve main body can be locked so that a phenomenon of poor contact caused by loosening of a fastening bolt structure in the use process can be prevented.

Description

technical field [0001] The invention belongs to the technical field of cable connectors, and more specifically relates to a special cable adapter device for electrical engineering. Background technique [0002] In electric power engineering, it is necessary to connect cables and control boxes. At present, when cables are connected to control boxes, adapters are often used for connection. [0003] For example, application number: CN201280021779.4, the present invention relates to a cable connector (1), the cable connector includes an outer shell (22) and a first cable thread for receiving a first cable (2) A connector (6) and a second cable gland (26) for receiving the second cable (3), in which a wiring device (9) is provided on which the first cable (2) and the second cable (3) can be connected. A locking device (23) is provided, and when at least one cable threaded joint (6, 26) and the outer shell are tightened, the locking device locks the cable threaded joint (6, 26) ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a special cable adapter device for electrical engineering to solve the existing problem of poor connection stability. In order to ensure the fastness of the connection and the smoothness of the signal, the existing The adapters are equipped with fastening bolts to enhance the degree of fastening, but especially the fastening bolts on the adapters on mobile joint equipment are easy to loosen after a period of use, which leads to unstable signal transmission , and there are many adapters on the electrical equipment, and the elimination process will inevitably need to waste more time, and the problem of anti-loosening cannot be solved at the root; moreover, the practicability is poor, and the existing equipment, especially the outdoor use Most of the electrical equipment has been improved accordingly to enhance the rainproof, but its structure is single, and it is impossible to organically combine the rainproof structure and connection strength
