Tensile high-speed data cable

Abstract

The invention discloses a tensile high-speed data cable, which comprises eight copper conductor pairs, a second insulating layer, a polyester tape layer, a second aluminum composite layer and a braided shielding layer, wherein the second insulating layer coats two copper conductor pairs of the eight copper conductor pairs; the other six copper conductor pairs in the eight copper conductor pairs are adhered to the second insulating layer; the polyester tape layer is coated on the other six copper conductor pairs in the eight copper conductor pairs; the second aluminum composite layer is coated on the polyester tape layer and consists of a polyester film layer and an aluminum film layer which is coated on the surface of the polyester film layer; the braided shielding layer is coated on an aluminum foil layer and comprises a plurality of strands of aramid fibers of which the sections are circular; a flat copper wire of which the section is rectangular and which is coated with a tin layer is lapped on the aramid fibers; and the braided shielding layer is braided by the plurality of strands of aramid fibers. By the high-speed data cable, the tensile fatigue resistance is improved, and the shielding performance of the cable is improved.

Description

technical field [0001] The invention relates to the field of high-speed data cables, in particular to a stretch-resistant 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 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, clamp the cable w...

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.
