Abstract

The invention relates to the technical field of cable connection and discloses a plug-in three-core cable intermediate joint. The cable joint comprises a casing and three identical connecting mechanisms arranged inside the casing, the connecting structures comprise connecting bodies and clamping bodies, two ends of each of the connecting bodies are provided with two circular openings, and the clamping bodies matched with the circular openings are set in the circular openings at two ends of the connecting bodies. The cable joint of the invention has the advantages that the core wire connectionoperation is simple and convenient, the quick connection of a cable core wire can be achieved, the sealing performance is good, and the waterproof effect is good.

Description

technical field [0001] The invention relates to the technical field of cable connection, in particular to a plug-in three-core cable intermediate joint. Background technique [0002] With the development and growth of my country's electric power industry, communication industry and urban rail transit industry, the demand for cables is also growing rapidly. When cables are used in the above fields, they usually need to be made into a continuous line, and each section of the line must be connected as as a whole, and these connection points are called cable glands. The cable joint in the middle part of the cable line becomes the middle joint. Its main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level of the cable joint, so that it can run safely and reliably. Chinese patent publication CN207504549U discloses a new type of cable cold-shrinkable three-core intermediate joint. The intermediate joint includes a body, a cold-shrinkabl...
