Network data communication cable is that single line is through twisting operation, then several groups of strands will be twisted into certain laying up pitch circular configuration to line and carry out sheath again, this structure not only can be because workmen's pulling force is excessive, undue force causes the pitch that cable inner wire is right to change because stretching, thereby has influence on digital cable to every electric transmission performance when construction wiring.The structure of telephone communication cable: the structure of common cable is that single line as the circular configuration of sheath, is mainly laid in residence interior trims netting twine or computer local area machine room to use PVC after stranding through strand.
Summary of the invention
The utility model provides a kind of high-temperature resistant network data communication cable, and the not separated or layering of this high-temperature resistant network data communication cable restrictive coating, had both realized high insulation, also realized corrosion-resistant, reliability and the life-span of having improved product.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-temperature resistant network data communication cable, comprise steel wire and 4 heart yearns that are coated with polyethylene layer, this heart yearn is comprised of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface that are positioned at center;
The first restrictive coating is coated on 2 described copper conductor outer surfaces, and the second restrictive coating is coated on steel wire outer surface; One bar shaped connecting portion is between the first restrictive coating and the second restrictive coating, and this bar shaped connecting portion arranged on left and right sides is equipped with v-depression; Described the first restrictive coating is comprised of with the thermoplastic urethane layers that is positioned at outside the polyvinyl chloride layer that is positioned at inner side, and the first polyethylene rope, the second polyethylene rope are positioned at bar shaped connecting portion inside and lay respectively at v-depression both sides.
In technique scheme, further improve technical scheme as follows:
1. in such scheme, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections.
2. in such scheme, the number of slugs on described polyvinyl chloride layer surface is 8.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model high-temperature resistant network data communication cable, its heart yearn is comprised of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface that are positioned at center, guaranteeing on the basis of self-supporting cable tensile strength, by adopting the both sides in the middle of neck respectively to increase V-type groove one, the first polyethylene rope, the second polyethylene rope is positioned at bar shaped connecting portion inside and lays respectively at v-depression both sides, V-type recess width 0.2 ~ 0.5mm, the degree of depth 0.2 ~ 0.5mm, existence due to groove, when cable is torn under tension, stress point all can concentrate on V-type groove part, cable is easy to just separated, and can not destroy the cable core of cable, secondly, described the first restrictive coating is comprised of with the thermoplastic urethane layers that is positioned at outside the polyvinyl chloride layer that is positioned at inner side, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections, under pulling force effect, both realized high insulation, realized corrosion-resistantly, and restrictive coating is not separated or layering, reliability and the life-span of having improved product yet.
