[0002] Communication cables are cables for transmitting telephone, telegraph, fax documents, television and radio programs, data and other electrical signals. They are composed of one or more pairs of mutually insulated conductors twisted together. Compared with overhead open lines, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less influence by natural conditions and external interference. When connecting, existing communication cables are connected by winding the copper wires at both ends together and wrapping them with electrical tape. However, the wrapping of the tape and the winding of the two sections of the communication cable themselves make them less stable. When the cable has a certain tension, the connection is prone to breakage. At the same time, when connecting, the communication cable is usually wrapped with insulating tape, which is easy to age and the cable connection is exposed, which leads to the problem of short service life of the communication cable, poor connectivity, slow wiring efficiency, and unstable connectivity.
