Abstract

The utility model relates to a six-core composite cable for high-speed data transmission. The six-core composite cable comprises insulating wires, two pairs of shielded twisted pair cables, filling cores, an isolating layer, a total shielding layer and a sheath, wherein each insulating wire is formed by extruding an insulating layer outside a conductor with a diameter of 0.75mm; the two insulating wires, the two pairs of shielded twisted pair cables and the two filling cores are twisted in pairs; the isolating layer is lapped outside the two insulating wires, the two pairs of shielded twisted pair cables and the two filling cores; the total shielding layer is braided outside the isolating layer; and the sheath is extruded from the total shielding layer. The six-core composite cable for high-speed transmission has the advantages that the cable has a complex multi-core structure, is good in softness, high in matte degree and high in anti-electromagnetic interference, and the like.

Description

A kind of six core composite cables for the data high-speed transmission

Technical field

The utility model relates to a kind of composite cable, particularly a kind of six core composite cables for the data high-speed transmission.

Background technology

The soft protective layer grade polyvinyl chloride plastic sheath of the many uses of common cable, flexibility is not good, and inferior luminosity is relatively poor; The wrapped shielding of the many uses of shielding, anti-electromagnetic interference effect is relatively poor.

Summary of the invention

Deficiency in view of the prior art existence, the utility model provides a kind of six core composite cables that are used for the data high-speed transmission that transfer of data, signal controlling, power supply are controlled to be one that collect, this cable multicore structure is complicated, has a cable soft type good, the characteristics such as inferior luminosity is better, anti-electromagnetic interference.

The utility model for achieving the above object, the technical scheme of taking is: a kind of six core composite cables for data high-speed transmission is characterized in that: be included in 0.75mm ²Conductor extrudes the insulated wire that a layer insulating consists of outward, also comprise two pairs of paired shield cables, filled core, separator, total screen, sheath, two described insulated wires, two pairs of described paired shield cables and two described filled core pair twists, outside it successively wrapped one deck separator, establishment one deck total screen, extrude one deck sheath.

The beneficial effects of the utility model are: adopt the tinned wird conductor, it has excellent conductive capability, has reduced the resistance of conductor.Adopt polyethylene insulation, have excellent electric property, its dielectric constant is 2.25～2.35, and dielectric loss angle tangent is about 5 * 10 ^-4, wherein lower dielectric constant is the basic assurance of low decay, low electric capacity.Guaranteed that with separator and the Polyamide Yarns filled core that polyester film consists of the cable rounding further improves insulating capacity simultaneously by electric insulation.Screen all adopts tinned wird, shielding has good oxygen-proof property and weldability, more effectively prevent between inner each the line group of cable and the interference of outer bound pair cable, sheath adopts 70 ℃ of gentle soft protective layer grade butyronitrile flexible PVC compounds to make the flexibility of cable and inferior luminosity more outstanding, makes whole cable possess excellent transmission and antijamming capability in conjunction with the insulation of 2 pairs of paired shield cables and low-k.
