Abstract
The utility model discloses a computer cable comprising a plurality group of double-conductor twisted insulation wire cores, wrapping bands winding on the double-conductor twisted insulation wire cores and a general shielding layer and a sheath orderly wrapping outside the wrapping bands, wherein each double-conductor twisted insulation wire core comprises a twisting pair twisted by two conductors respectively wrapping insulating layers and an individual shield wrapping the twisting pair. The polyethylene is high in insulation resistance, and excellent in voltage resistance. The dielectric coefficient is low, and the influence of medium loss temperature and the frequency conversion is small. The novel computer cable satisfies the requirement of transmission performance, and ensures the service lifetime of the cable. In order to reduce the crosstalk and external interference of the loops, the cable employs a shield structure. The computer cable is generally shielded after shielding of the twist pairs of the cable. Therefore, the cable is excellent in signal transmission quality and long in service lifetime.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of novel computer cable.
Background technology
The electronic computer cable is that electronic computer is connected with automation and uses cable, is applied to fields such as electric power, chemical industry, petrochemical refining, metallurgy, light textile.Owing in different occasions, specific mounting condition or strong electromagnetic, cable can not be produced a desired effect.Need a kind of novel computer of design can satisfy the requirement of transmission performance and the useful life that can guarantee cable with cable.
The utility model content
The purpose of this utility model is to provide a kind of novel computer cable.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of computer cable, it comprise many group two-conductor pair twist insulated wire cores, wrapped on the described two-conductor pair twist insulated wire cores of many groups band and be wrapped in total screen and sheath band outside successively, the strand that forms behind two conductor pair twists of described two-conductor pair twist insulated wire cores by wrap insulate layer respectively shields the phase-splitting external with being wrapped in described strand to be formed.
Above-mentioned computer cable, its described two-conductor pair twist insulated wire cores is 8 ~ 16 groups.
Above-mentioned computer cable, its described conductor is copper.
Above-mentioned computer cable, the material of its described insulating barrier are polyethylene.
Above-mentioned computer cable, the material of its described sheath are polyvinyl chloride.
The beneficial effects of the utility model:
Poly insulation resistance height, proof voltage is good, and dielectric coefficient influence little and dielectric loss temperature and frequency conversion rate is also little, not only can satisfy the requirement of transmission performance, and the useful life that can guarantee cable.In order to reduce crosstalking mutually and external disturbance between the loop, cable adopts shielding construction.Computer of the present utility model adopts the total screen method in pair twist combination shielding back with cable.Signal transmission quality is arranged preferably and than the long life.
