Abstract
The invention discloses a cable for a computer. The cable comprises an insulated wire core formed by twisting multiple groups of double conductors in pairs, a wrapping tape wrapping the insulated wire core formed by twisting multiple groups of double conductors in pairs, a total shielding layer and a sheath, wherein the total shielding layer and the sheath sequentially wrap the wrapping tape, and the insulated wire core formed by twisting multiple groups of double conductors in pairs consists of twisted pairs formed by respectively twisting every two conductors wrapped by insulating layers and a split-phase shield wrapping the twisted pairs. The insulation resistance of polyethylene is high, voltage resistance is good, a dielectric coefficient is small, the influence of dielectric loss temperature and frequency variation is also small, the transmission performance requirement can be met, and the service life of the cable can be ensured. For reducing mutual crosstalk of loops and external disturbance, the cable adopts a shielding structure. The cable for the computer adopts a total shielding method integrating paired twisting and shielding and has good signal transmission quality and long service life.
Description
Technical field
The invention belongs to cable technology field, be specifically related to a kind of novel computer cable.
Background technology
Cable for electronic computer is electronic computer and automation cable for connecting, is applied to the fields such as electric power, chemical industry, petrochemical refining, metallurgy, light textile.Due in different occasions, specific mounting condition or strong electromagnetic, conventionally can make cable not produce a desired effect.Need to design a kind of novel computer and can meet the requirement of transmission performance with cable, and can guarantee the useful life of cable.
Summary of the invention
The object of the present invention is to provide a kind of novel computer cable.
Object of the present invention can be achieved through the following technical solutions:
A kind of computer cable, it comprises many group two-conductor pair twist insulated wire cores, wrapped band in the described two-conductor pair twist insulated wire cores of many groups and is wrapped in successively total screen and the sheath outside band, and the strand forming after two conductor pair twists of described two-conductor pair twist insulated wire cores by wrap insulate layer respectively forms the phase-splitting shielding external with being wrapped in described strand.
Above-mentioned computer cable, the two-conductor pair twist insulated wire cores described in it is 8 ~ 16 groups.
Above-mentioned computer cable, the conductor described in it is copper.
Above-mentioned computer cable, described in it, the material of insulating barrier is polyethylene.
Above-mentioned computer cable, described in it, the material of sheath is polyvinyl chloride.
Beneficial effect of the present invention:
Poly insulation resistance is high, and proof voltage is good, and dielectric coefficient impact little and dielectric loss temperature and Frequency is also little, not only can meet the requirement of transmission performance, and can guarantee the useful life of cable.In order to reduce mutually crosstalking and external disturbance between loop, cable adopts shielding construction.Computer of the present invention adopts the rear total screen method of pair twist combination shielding with cable.There is good signal transmission quality and compared with the long life.
Accompanying drawing explanation
Fig. 1 is computer construction of cable figure.
