Abstract
一种计算机电缆，属于电缆。主要解决现有计算机电缆存在的自身抗干扰能力不强，防外界电磁干扰效果不好的缺点。本实用新型包括多组由内铜带屏蔽绕包的对绞线芯组、填充物、外铜带屏蔽、聚酯绕包带和外护套，其中，每组对绞线芯组均设有两根带有绝缘的导体，其特征在于所说绝缘外还设有半导电屏蔽层。本实用新型不仅能使对绞线芯组之间的抗干扰能力更强，从而显著提高计算机电缆的抗电磁干扰能力，而且还具有均匀电场，使传输信号稳定不波动。
A computer cable belongs to cables. The invention mainly solves the shortcomings of existing computer cables, such as weak anti-interference ability and poor effect of preventing external electromagnetic interference. The utility model includes multiple pairs of twisted wire core groups wrapped by inner copper tape shielding, fillers, outer copper tape shielding, polyester wrapping tapes and outer sheaths, wherein each pair of twisted wire core groups is equipped with Two conductors with insulation are characterized in that a semi-conductive shielding layer is provided outside the insulation. The utility model can not only make the anti-interference ability between the twisted wire core groups stronger, thereby significantly improving the anti-electromagnetic interference ability of the computer cable, but also has a uniform electric field, so that the transmission signal is stable and does not fluctuate.
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.
