In technique scheme, further improvement opportunity scheme is as follows:
1. in such scheme, described v-depression width is 0.2 ~ 0.5mm, and the degree of depth is 0.2 ~ 0.5mm.
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 reliability transmitting voice signal cable, its heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, on the basis ensureing self-supporting cable tensile strength, one v-depression is respectively increased by adopting the both sides in the middle of neck, v-depression width 0.2 ~ 0.5mm, the degree of depth 0.2 ~ 0.5mm, due to the existence of groove, cable is when under tension is torn, stress point all can concentrate on v-depression part, cable is easy to just separated, and can not destroy the cable core of cable; Secondly, described first restrictive coating is made up of with the thermoplastic urethane layers being positioned at outside the polyvinyl chloride layer being positioned at inner side, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections, under a stretching force, both high insulation had been achieved, also achieve corrosion-resistant, and restrictive coating is not separated or layering, improves reliability and the life-span of product.
