Description
Technical field
The utility model relates to technical field of cables, in particular to a kind of heat-resistant antifriction cable.
Background technique
Existing to surpass be only that internal conductor pair twist is arranged in five class pair twist cables, and the integrally stretching for reinforcing cable is strong
Degree, and shielded layer is added in outside to increase shield effectiveness；The cable of this structure, be first after inner conductor pair twist mutually
Between can generate signal interference, in particular for the paired cable of multi-conductor structure, shield effectiveness is bad, and another convenience is exactly more
The case where squeezing mutually between conductor group can all occur in the cable of conductor structure, reduce tensile strength.And cable makes in installation
With abrasion can be often subject in the process, will be destroyed over time.
Utility model content
The utility model provides a kind of heat-resistant antifriction, is hardly damaged, the good network cable of shield effectiveness, to realize above-mentioned mesh
, the utility model uses following technical scheme: a kind of heat-resistant antifriction cable, including core are set on the outside of the core
Regular triangular prism tube body, it is characterised in that side is uniformly divided into four small regular triangular prism tube body, the line in the triangular prism tube body
Core includes four groups of twisted pairs, and each group of twisted pair includes two conducting wires, insulating layer is coated with outside every conducting wire, two are led
Pair twist stranding after body is coated via insulating layer further includes the internal shield being wrapped on the outside of twisted pair, also coats outside internal shield
There is inner sheath；Each group of twisted pair is respectively arranged in the small regular triangular prism tube body, is also set on the outside of the regular triangular prism tube body
It is equipped with external shielding layer, further includes the rubber tube being wrapped on the outside of the external shielding layer outside, the external shielding layer and the plantation rubber
It is filled with glass silk floss between pipe, flame-retardant layer is enclosed on the outside of the rubber tube, wraps up oversheath on the outside of the flame-retardant layer.
Preferably, the internal shield is foil shielding layer.
It may further be preferable that the external shielding layer is tinned copper wire woven mesh layer.
Preferably, the oversheath is polytetrafluoroethylene material.
Preferably, multiple reinforcing rings are arranged at intervals on the oversheath.
It may further be preferable that the reinforcing ring and the oversheath are integrally designed, the reinforcing ring is with a thickness of 1-2 milli
Meter, spacing is no more than 10 centimetres between two adjacent reinforcing rings.
In the technical solution adopted in the utility model, which is set by the double layer screen of internal shield and external shielding layer
Set, good net mask can be played the role of, utmostly the drawbacks of signal decaying so that signal is more steady in the transmission
It is fixed and quick, in addition twisted pair is separated with small regular triangular prism tube body, four strands of twisted pairs is avoided mutually to wind interference, regular triangular prism
Tube body peripheral hardware rubber tube, rubber tube outside are enclosed with flame-retardant layer, wrap up oversheath on the outside of the flame-retardant layer, greatly strengthen
The compression strength and wear-resisting property of cable, also increase heat resistance, so that cable is durable.
