High-reliability data cable having buffering performance

Abstract

The invention discloses a high-reliability data cable having buffering performance. The data cable includes an insulating layer, a fireproofing separating layer, a thin aluminium powder layer, a metal protective layer, and a silicone rubber inner sheath that wrap from the outside to the inside, the outer wall of the insulating layer is outwardly connected with a wirerope protection layer through a connection part, a wire rope parallel to the insulating layer is inserted into the wirerope protection layer, a filler layer is arranged inside the silicone rubber inner sheath, the silicone rubber inner sheath is provided with four silicone rubber projections having the arc-shaped cross sections, each silicone rubber projection is internally provided with a buffering cavity, a clamp groove is arranged between adjacent silicone rubber projections, and a twisted pair simultaneously abutting against the filler layer is arranged in each clamp groove. The twisted pair is firmly fixed by the four silicone rubber projections along the inner surface of the silicone rubber inner sheath, so that the stability of the overall structure is improved; and the buffering cavities arranged in the silicone rubber projections enhance the buffering performance of the structure and reduce the impact of the external giant force on the twisted pair.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data connection line. Background technique [0002] In the information age, the importance of data transmission is self-evident. In fact, data transmission components such as data connection lines are indispensable. Common data lines in LAN mainly include twisted pair, coaxial cable, and optical cable. A twisted pair is a data transmission line composed of many pairs of wires. It is characterized by low price, so it is widely used, such as our common telephone lines. It is used to connect with the RJ45 crystal head. It has two kinds of STP and UTP, and we commonly use UTP. The network cable consists of eight copper wires. In order to reduce the mutual interference of electromagnetic signals, every two wires are twisted together at a certain density. In this way, the electric waves radiated from each other during the transmission of electric signals will cancel ea...
