Description
Technical field
The utility model relates to a kind of built on stilts cable, relates in particular to a kind of high resiliency overhead type data cable.
Background technology
Data cable is that single line is through twisting operation, then several groups of strands will be twisted into circular configuration with certain laying up pitch 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 in the time of 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 resiliency overhead type data cable, and this high resiliency overhead type data cable has been improved the transmission performance of cable, has improved again pliability, prevents that frequent bending from causing polyethylene layer cracking, and easily separated and can not destroy the cable core of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high resiliency overhead type data cable, comprise that steel wire and 2 are coated with the heart yearn of polyethylene layer, this heart yearn is made up 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 4 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 made up 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 described polyethylene layer, edge is circumferentially distributed with several pores.
In technique scheme, further improve technical scheme as follows:
1. in such scheme, the number of slugs on described polyvinyl chloride layer surface is 8.
2. in such scheme, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model high resiliency overhead type data cable, its heart yearn forms and is ensureing on the basis of self-supporting cable tensile strength by being positioned at the polyethylene strip at center and stranded 6 copper conductors in polyethylene strip outer surface, by adopting the one V-type groove of the each increase in both sides in the middle of neck, the first polyethylene rope, the second polyethylene rope are positioned at bar shaped connecting portion inside and lay respectively at v-depression both sides, 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 made up 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, in external sheath layer, all have and contain several cavities, under pulling force effect, both realized high insulation, also realized corrosion-resistant, and restrictive coating does not separate or layering, reliability and the life-span of product are improved, also improved the transmission performance of cable, improved again pliability, prevented that frequent bending from causing polyethylene layer cracking.
