Abstract
A computer cable belongs to a cable, and mainly solves the shortcomings of an existing computer cable which has weak self anti-interference capability and bad effect of preventing external electromagnetic interference. The computer cable comprises a plurality of groups of pair twist core groups which are wounded by an inner copper belt barrier, filler, an outer copper belt barrier, a polyester wounding belt and an oversheath, wherein each group of pair twist core groups is provided with two insulating conductors. The computer cable is characterized in that semi-conducting shielding layers arefurther arranged outside the insulating conductors. The computer cable can make the anti-interference capacity between the twisted wire groups stronger, thereby obviously improves the anti-electromagnetic interference capacity of the computer cable, and the computer cable further has even electrical fields, and leads transmission signals to be stable without fluctuation.
Description
Technical field
The utility model belongs to cable, specifically a kind of computer cable that is used for the computer transmission signals.
Background technology
Self antijamming capability of active computer cable is not strong, and anti-outside electromagnetic interference effect is bad, and the signal transmission is subject to outer electromagnetic interference, makes signal erratic fluctuations occur.
Summary of the invention
The purpose of this utility model is to provide at above-mentioned deficiency that a kind of simple in structure, anti-electromagnetic interference capability is strong, the computer cable of stable signal transmission.
The utility model is achieved in that and comprises that many groups are by the wrapped pair twist core group of interior copper strips shielding, filler, the shielding of outer copper strips, polyester twining package tape and oversheath, wherein, every group of pair twist core group is equipped with two conductors that have insulation, it is characterized in that said insulation also is provided with semiconductive shielding layer outward.
Above-mentioned pair twist core group has three groups.
The utility model is by increasing semiconductive shielding layer, can not only make the antijamming capability between the pair twist core group stronger, thereby significantly improve the anti-electromagnetic interference capability of computer cable, but also has uniform electric field, steady signal transmission is not fluctuateed, and the stability of signal transmission can be brought up to more than 97% by original 94%.
Description of drawings
Accompanying drawing is the utility model structural representation, copper strips shielding in the 1--, 2--insulation, 3--conductor, 4--filler, the outer copper strips shielding of 5--, 6--polyester twining package tape, 7--oversheath, 8--semiconductive shielding layer.
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: conductor 3 adopts anneal circle copper, extrude the insulation 2 of making on it by polyvinyl chloride or polyethylene or cross-linking polyethylene materials, insulation 2 outer one decks that extrude again shield the semiconductive shielding layer 8 that material constitutes by the semiconductive polypropylene, per two conductor 3 outer wrapped interior copper strips shieldings 1 that have semiconductive shielding layer 8 and insulation 2 constitute one group of pair twist core group, three groups of pair twist core groups are 120 ° of uniform strandings of angle by the cross section, be filled with therebetween and guarantee the cable roundness, fill the filler 4 that rope constitutes by polypropylene, and be enclosed with outer copper strips shielding 5 successively, polyester twining package tape 6 and oversheath 7 promptly become the utility model.
Claims (2)
1, a kind of computer cable, comprise that many groups are by the wrapped pair twist core group of interior copper strips shielding, filler, the shielding of outer copper strips, polyester twining package tape and oversheath, wherein, every group of pair twist core group is equipped with two conductors that have insulation, it is characterized in that said insulation also is provided with semiconductive shielding layer outward.
2, by the described computer cable of claim 1, it is characterized in that said pair twist core group has three groups.
