Tensile anti-fatigue high-speed data cable

Abstract

The invention discloses a tensile anti-fatigue high-speed data cable which comprises eight copper conductor pairs; two of eight copper conductor pairs are coated by a second insulating layer; the other six of eight copper conductor pairs are covered on the second insulating layer; the other six of eight copper conductor pairs are coated by a polyester tape layer; the polyester tape layer is coated by a second aluminum plastic composite layer; the second aluminum plastic composite layer comprises a polyester thin film layer and an aluminum thin film layer which coats on the surface of the polyester thin film layer; an aluminum foil layer is coated by a woven shielding layer; the woven shielding layer comprises a plurality of aromatic nylon fibers with a circular section and a plurality of tinning copper wires; the aromatic nylon fibers are coated by a tinning flat copper wire with a rectangular section; and the woven shielding layer comprises a plurality of aromatic nylon fibers and a plurality of tinning copper wires which are crossed and woven. The high-speed data cable provided by the invention enhances tensile anti-fatigue performance and also enhances the shielding performanceof the cable at the same time of ensuring the resistance of the shielding layer.

Description

technical field [0001] The invention relates to the field of high-speed data cables, in particular to a high-speed data cable resistant to stretching and fatigue. 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 and aluminum-plastic composite tape (the aluminum layer faces outward), then tinned annealed copper wire is braided and shielded, and the outer sheath is made of PVC material. Since the product is used as a hot-swappable cable, a bending fatigue test is required. The usual test method is to take a 60cm long conductor, connect the cable conductor, braided copper wire, ground wire and other conductor materials in series,...

AI Technical Summary

Problems solved by technology

Especially for braided shielding, the tensile and extrusion force is greater, and the copper wire is easily broken, which makes the signal transmission of the product unstable or even loses the transmission function.
