Ultra-flexible indoor high-speed data cable

Abstract

The invention discloses a super-flexible indoor high-speed data cable which comprises eight bunch-stranded wire cores. The surface of each flexible round wire is coated with a tin coating. The wire cores are pairwise stranded to form a white-blue shielded twisted pair, a white-orange shielded twisted pair, a white-green shielded twisted pair, and a white-brown shielded twisted pair. The four shielded twisted pairs are parallelly disposed in a same plane. A sheath layer wraps the outer surfaces of the four shielded twisted pairs. Each two adjacent shielded twisted pairs are isolated by the sheath layer. The sheath layer 15 mainly comprises 49% of polyvinyl chloride resin, 8.27% of calcium carbonate, 18.5% of dimethyl phthalate, 22.5% of trioctyl trimellitate, 0.21% of pentaerythritol ester, 2.2% of composite lead salt stabilizer, and 0.32% of polyvinyl chloride antistatic agent. The super-flexible indoor high-speed data cable features super flexibility, effectively prevents entry of external electromagnetic interference, also prevents outward radiation of internal signals, and is conducive to electrostatic elimination.

Description

technical field [0001] The invention relates to the field of high-speed data cables, in particular to an ultra-flexible indoor high-speed 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 reno...

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 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, wasting space resources, and If the wiring is remodeled in an old residential area, it needs to be wired in the room, and the round appearance is not conducive to wall fixing and aesthetics; therefore, the portable soft and anti-interference indoor high-speed data cable overcomes the above difficulties and will be used in the future. It is the new favorite product in the wiring system
