Flat type anti-interference data cable

Abstract

The invention discloses a flat type anti-interference data cable, which comprises eight bunch-stranded wire cores; tin layers are plated on the surfaces of all soft circular conducting wires; the bunch-stranded wire cores are pairwise stranded to form a white blue shielding pairwise-stranded group, a white orange shielding pairwise-stranded group, a white green shielding pairwise-stranded group and a white brown shielding pairwise-stranded group; the four pairs of shielding pairwise-stranded groups are placed in parallel and positioned in the same plane; a sheath layer is coated on the outer surfaces of the four pairs of shielding pairwise-stranded groups, and adjacent shielding pairwise-stranded groups are isolated from each other through the sheath layer; and the sheath layer is mainly formed by materials with the mass percentages as follows: 45 percent to 50 percent of polyvinyl chloride (PVC) resin, 8 percent to 10 percent of calcium carbonate, 14 percent to 22 percent of phthalicacid methyl ester, 21 percent to 23 percent of trioctyl trimellitate, 0.18 percent to 0.22 percent of pentaerythritol ester, 2.0 percent to 2.5 percent of compound lead salt stabilizing agents and 0.3 percent to 0.36 percent of PVC antistatic agent. The cable disclosed by the invention has a characteristic of super flexibility; external electromagnetic interference can be effectively prevented from entering the cable, and meanwhile, internal signals can be prevented from being radiated out; and besides, the electrostatic elimination is facilitated.

Description

technical field [0001] The invention relates to the field of high-speed data cables, in particular to a flat anti-interference data cable. Background technique [0002] The structure of the existing high-speed data cable is to extrude foamed polyolefin insulation on the silver-plated annealed copper wire conductor, and wrap aluminum-plastic composite tape around two insulating core wires to form a shielded pair. After multiple shielded wire pairs are assembled into a cable, the cable core is wrapped with non-hygroscopic insulating tape, aluminum-plastic composite tape (the aluminum layer faces outward), and then tinned annealed copper wire is braided and shielded, and the outer sheath of PVC material, due to its Due to the particularity of the structural design, basically all data cables are circular in structure, and due to the special shielding structure, their overall appearance is relatively large, which occupies a lot of pipe space when the home is newly renovated, wast...

Problems solved by technology

After multiple shielded wire pairs are assembled into a cable, the cable core is wrapped with non-hygroscopic insulating tape, aluminum-plastic composite tape (the aluminum layer faces outward), and then tinned annealed copper wire is braided and shielded, and the outer sheath of PVC material, due to its Due to the particularity of structural design, basically all data cables are circular in structure, and due to the special structure of shielding, their overall appearance is relatively large, which occupies a lot of pipe space when the home is newly renovated, wasting space resources, and If the wiring is remodeled in an old-style residential area, it needs to be wired in the room, and the round appearance is not conducive to fixing the wall and making it beautiful; therefore, the portable soft and anti-interference flat data cable overcomes the above difficulties and will definitely be used in the future.
