Flexible cable for multi-core communication power supply applied to communication equipment

Abstract

The invention discloses a flexible cable for a multi-core communication power supply applied to communication equipment. The flexible cable comprises aluminium cores, two power copper conductive wires, two data copper conductive wires and a herringbone framework, wherein the two data copper conductive wires are coated with shield and insulation layers respectively, the outer surface of a flame-retardant layer is coated with an outer sheath layer, and an insulation foaming layer, a single-sided aluminium foil layer and an inner sheath layer are located in a first cavity, a second cavity and a third cavity of the herringbone framework respectively; each shield and insulation layer is composed of the following components in parts by weight: 1,3-butadiene, styrene, ethylene-vinyl acetate copolymer, chlorinated polyethylene, diisodecyl phthalate, polythiophene, siloxane, gas-phase white carbon black, copper powder, polyethylene wax, titanium dioxide, 4,4'-bi(alpha,alpha-dimethyl benzyl)diphenylamine, dicumyl peroxide, triallyl cyanurate and dilauryl thiodipropionate. According to the flexible cable disclosed by the invention, reflection and absorption for low frequency electromagnetic waves can be enhanced, the crosslinking intensity of a matrix can be improved and meanwhile crosstalk and signal attenuation are improved, and the good stretching and tearing intensity physical and mechanical properties are good.

Description

technical field [0001] The invention relates to a flexible cable, in particular to a multi-core communication power supply flexible cable applied to communication equipment. Background technique [0002] In our existing integrated wiring system, generally use 4 pairs of ordinary digital cables for Internet access, data transmission, etc., use local telephone cables for wiring, telephone, voice transmission, etc., use ordinary coaxial cables for network TV, high-definition TV Watching, etc., when the above cables are wired, they need to be wired in the same pipeline to affect and interfere with each other. [0003] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at low frequencies becomes more and more prominent, which seriously affects the electrical performance of each cable, resulting in the comprehensive wiring of each cable to the home.

Problems solved by technology

[0002] In our existing integrated wiring system, generally use 4 pairs of ordinary digital cables for Internet access, data transmission, etc., use local telephone cables for wiring, telephone, voice transmission, etc., use ordinary coaxial cables for network TV, high-definition TV Watching, etc., when the above cables are wired, they need to be wired in the same pipeline to affect and interfere with each other

[0003] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at low frequencies becomes more and more prominent, which seriously affects the electrical performance of each cable, resulting in the comprehensive wiring of each cable to the home. The speed, the quality of telephone calls, and the definition of high-definition images will all be affected to varying degrees, and since each cable is an independent unit, after years of heating and heating, it is easy to cause the sheaths of the cables to stick to each other, etc. , eventually lead to broken skin, even leakage, burning, and eventually a fire
