Problems solved by technology
[0003] In the prior art, a large number of communication cables need to be used in trains. After the communication cable connectors are arranged on site, if the wiring harness is twisted or dragged by external force, it is very easy to cause the connection to loosen and fall off, which not only causes connection failure, but also causes signal failure. The transmission is not stable enough, and it also has certain security risks

The invention is suitable for the technical field of cable connection, and provides a communication cable joint structure, which comprises an outer fixed part fixed on an outer component, an inner movable part and a wiring lantern ring, wherein the inner movable part is coaxially arranged in the outer fixed part, and the inner movable part and the outer fixed part independently rotate relative to each other; and the wiring lantern ring is fixedly installed in the inner movable part, a wiring mechanism is arranged in the wiring lantern ring and used for being connected with a cable, and the part, located in the inner movable part, of the cable is twisted to be of a spring-shaped structure. The communication cable joint structure has the beneficial effects that external force dragging, traction and twisting can be effectively compensated and buffered, and the stability of cable connection is guaranteed.
Description
technical field [0001] The invention relates to a cable joint, in particular to a communication cable joint structure and an installation method thereof. Background technique [0002] With the advancement of science and technology, the communication industry has been greatly developed, and the application of communication cables is becoming more and more extensive; communication cables are cables used to transmit telephones, telegraphs, fax files, TV and radio programs, data and other electrical signals , which includes the cable core and the outer sheath located outside the cable core. The number of cable cores can be set to different numbers according to their usage requirements. The installation methods include overhead, direct burial, pipeline and underwater laying methods. [0003] In the prior art, a large number of communication cables need to be used in trains. After the communication cable connectors are arranged on site, if the wiring harness is twisted or dragged ...
