High-frequency anti-interference data cable

Abstract

The invention provides a high-frequency anti-interference data cable. The high-frequency anti-interference data cable comprises a cable core and a protection layer which is wrapped on the cable core, wherein the cable core is composed of 6 to 8 threads of cable core units which are arrayed in a bundle shape and are stranded and molded; the outer layer of each thread of cable core unit is coated with an insulating anti-interference film layer which is obtained by drying and molding insulating anti-interference slurry in claim 1; the coating thickness of the insulating anti-interference film layer is 80mu m to 200mu m; an anti-interference composite layer is molded on the inner surface of the protection layer, wherein the insulating anti-interference film layer is prepared by coating the surface of each cable core unit with 80mu m to 200mu m of the slurry; the anti-interference composite layer is composed of a metal fiber textile layer, a polyvinyl chloride resin layer and a conductive high-polymer fiber layer in sequence from the protection layer to the inside; a polytetrafluoroethylene layer is further molded on the inner surface of the conductive high-polymer fiber layer. According to the high-frequency anti-interference data cable provided by the invention, the anti-interference performance of the data cable can be effectively improved; meanwhile, the transmission stability of the data cable under a high-frequency working condition can be effectively met.

Description

Technical field [0001] The invention relates to data line technology in the field of data conduction technology, in particular to a high-frequency anti-interference data line. Background technique [0002] With the rapid development of the global information highway, with the increasing network rate and the popularization of local area network technology with a ratio of up to Gigabit, the digital cable of the local area network has been rapidly developed and applied on a large scale.

Problems solved by technology

[0003] Under the above technical conditions, the data line as the information transmission medium is put forward higher requirements. On the one hand, the transmission performance requirements of the data line are getting higher and higher. On the other hand, the higher and higher transmission rate , which means that as the operating frequency continues to increase, it is easier to generate electromagnetic radiation and capacitive coupling to cause data distortion and attenuation, especially the attenuation in the high frequency band above 2.75GHz is particularly serious

At the same time, there will be new sources of electromagnetic interference in the surrounding environment, so the application of the traditional transmission data line structure in an environment with large electromagnetic interference will often lead to communication failures
