Durable communication cable

Abstract

The invention discloses a durable communication cable, which belongs to the technical field of cables, and can realize coating type mechanical protection on a cable body by covering a specific area on the cable body with mutually lapped protective flakes, and cannot influence bending and stretching of the cable body in a normal range on the other hand, meanwhile, a certain gap is kept between the protective flakes and the cable body to meet heat dissipation, the inner supporting magnetic bundles at the inner ends of the protective flakes can provide an elastic buffering effect, damage caused by the fact that external force directly acts on the cable body is avoided, and even if the cable body cracks due to excessive bending or stretching, a magnetic attraction rubber bag on the inner side of the cable body attracts the corresponding inner support magnetic bundle to promote the inner support magnetic bundle to extend to the cracking part, and meanwhile, the magnetic attraction rubber bag can also be compressed to release glue to glue the cracking part, so that a temporary repairing effect is achieved, early warning is given to technicians, and the durability of the cable body can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of cables, more specifically, to a durable communication cable. Background technique [0002] Communication cables are cables that transmit telephone calls, telegrams, fax documents, TV and radio programs, data and other electrical signals. It consists of more than one pair of mutually insulated wires twisted together. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less affected by natural conditions and external interference. [0003] The communication cable is a communication line composed of a plurality of mutually insulated wires or conductors with a cable core and a sealed sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, i...

Problems solved by technology

[0004] Existing communication cables will inevitably be bent or stretched by external forces during laying and use, especially in complex environments, they are more likely to be damaged, and surface cracks appear. After the surface is cracked, the cable core is directly exposed to the outside world. In the environment, it is easy to be damaged by erosion, and once damaged, it will cause communication interruption, which will cause more serious losses
