Data cable with interference shielding function

Abstract

The invention discloses a data cable with an interference shielding function. The data cable comprises eight bunch stranded wire cores; a tin layer is plated on the surface of each soft round lead; every two of the eight bunch stranded wire cores are twisted with each other to form a white-blue shielded twisted group, a white-orange shielded twisted group, a white-green shielded twisted group and a white-brown shielded twisted group; the four shielded twisted groups are placed in parallel and positioned in the same plane, a sheath layer covers the outer surface of the four shielded twisted groups, and the adjacent shielded twisted groups are isolated through the sheath layer; and the sheath layer mainly comprises the following materials in percentage by mass: 47 to 48.27 percent of polyvinyl chloride (PVC) resin, 9 to 10 percent of calcium carbonate, 18 to 21.54 percent of dimethyl phthalate, 21 to 22 percent of trioctyl trimellitate, 0.18 to 0.2 percent of pentaerythritol ester, 2.0 to 2.2 percent of composite lead salt stabilizer, and 0.33 to 0.34 percent of PVC antistatic agent. The data cable has super flexibility, effectively prevents external electromagnetic interference from entering, blocks internal signals from being radiated out at the same time, and is beneficial to static elimination.

Description

technical field [0001] The invention relates to the field of data cables, in particular to a data cable with the function of shielding interference. 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 renov...

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.
