They are mainly suitable for signal transmission between various types of digital program-controlled switches in transmission equipment bureaus, internal connections of optoelectronic transmission equipment and distribution frames. They are used to transmit data, audio, video and other communication equipment.

[0003] In the existing cable connection process, if the cable length is not enough and wiring operation is required, two cables are usually connected by winding them together and wrapped with tape. Although tape winding is convenient, long-term use will cause line aging, and if the wrapping is not tight, it is easy to cause leakage and other problems. Once multiple cables need to be wired at the same time, the cables work with each other and generate heat, which will cause the tape to preheat, melt and deform, resulting in contact between multiple cables, short circuit and mutual interference, thereby affecting the normal use of the cable, and failing to provide stable transmission for the equipment, resulting in instability during use.
