Abstract
The utility model discloses a computer cable for signal transmission, the structure of which includes at least one pair-twisted cable core group (9), an external shielding layer (7) and an external protective layer (8) from inside to outside. Two parallel inner conductors (1) are arranged in each pair-twisted cable core group (9). An insulating layer (2) is arranged on the surface of each inner conductor (1). A semi-conductive shielding layer (3) is arranged outside each insulating layer (2). Water-blocking ropes I (51) are arranged between the semi-conductive shielding layers (3) and the inner shielding layers (4). Water-blocking ropes II (52) are arranged between the inner shielding layers (4) and the outer shielding layer (7). At the same time, a water-blocking belt (6) is also arranged. The computer communication cable has the advantages of being great in waterproofness, high in electromagnetic-interference resistant ability, stable in signal transmission and great in voltage resistant ability and the like.

Technical field
The utility model relates to a kind of cable, especially a kind of for transmitting the computer cable of Computer signal.
Background technology
Along with developing rapidly of national economy, computer cable application is more and more extensive, and computer cable requirement rated power is high, strong anti-interference performance, and water resistance is strong.Current conventional computer cable adds insulating barrier by conductor and sheath forms, and water resistance is poor, interference free performance is strong, signal transmission fluctuation is larger, brings certain hidden danger to much work.The generation of some accident, because water resistance and the anti-interference of cable do not cause by force.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of water resistance is good, anti-electromagnetic interference capability is strong, stable signal transmission, compunication cable that proof voltage ability is good.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
Signal transmission computer cable, in structure, comprise successively from inside to outside at least one group of pair twist core group, outer shielding layer and external sheath layer, in described every group of pair twist core group, be provided with two inner wires that are parallel to each other, on this inner wire surface, be provided with insulating barrier, this insulating barrier outside is provided with semiconductive shielding layer, this semiconductive shielding layer is filled with waterproofing rope I outward, this waterproofing rope I is outside equipped with internal shield, this internal shield is filled waterproofing rope II outward, this waterproofing rope II is outside equipped with waterstop, this waterstop is outside equipped with outer shielding layer, this outer shielding layer is outside equipped with outer jacket.
As a kind of optimal technical scheme of the present utility model, described pair twist core group has two groups, and two groups are arranged in parallel.
As a kind of optimal technical scheme of the present utility model, described semiconductive shielding layer is polypropylene layer.
As a kind of optimal technical scheme of the present utility model, described insulating barrier is polyvinyl chloride layer, polyethylene layer or rubber material layer.
As a kind of optimal technical scheme of the present utility model, described internal shield is copper strips twining package tape.
As a kind of optimal technical scheme of the present utility model, described outer shielding layer is proof copper-wire braided layer.
The beneficial effect that adopts technique scheme to produce is:
The utility model increases semiconductive shielding layer outward by the insulating barrier at every inner wire, anti-electromagnetic interference capability between inner two conductors of pair twist core group is strengthened, every group of pair twist core group is all provided with internal shield outward, antijamming capability between pair twist core group is strengthened, again in conjunction with outer shielding layer, comprehensively improved the anti-electromagnetic interference capability of computer cable, also had uniform electric field simultaneously, made computer cable signal transmission more stable.By be disposed with waterproofing rope II and waterstop between outer shielding layer and internal shield, between internal shield and semiconductive shielding layer, fill waterproofing rope I, greatly improved the vertical and horizontal water-resisting ability of cable, and then improved the water repelling property of cable, make construction of cable rounding more simultaneously, Stability Analysis of Structures, not fragile.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
In figure: 1, inner wire; 2, insulating barrier; 3, semiconductive shielding layer; 4, internal shield; 51, waterproofing rope I; 52, waterproofing rope II; 6, waterstop; 7, outer shielding layer; 8, outer jacket; 9, pair twist core group.
Embodiment
Referring to accompanying drawing, specific embodiment of the utility model adopts circle copper as inner wire 1, its outer surface extrudes the insulator 2 of being made by elastomeric material, outside insulator 2, extrude again the semiconductive shielding layer 3 that one deck consists of semi-conductive polypropylene shielding material, the outer wrapped internal shield 4 again of semiconductive shielding layer 3, internal shield 4 forms by copper strips is wrapped; Every two groups of inner wires 1, insulator 2, semiconductive shielding layer 3 and internal shield 4 form one group of pair twist core group 9, between internal shield 4 and semiconductive shielding layer 3, fill waterproofing rope I 51, two groups of pair twist core groups 9 are arranged in parallel, the waterproofing rope II 52 being composited by non-woven fabric of polyester fiber and high-absorbent material is therebetween filled, and the waterstop 6 being composited by non-woven fabric of polyester fiber and high-absorbent material is wrapped, waterstop 6 is wrapped with outer shielding layer 8 and outer jacket 8; Outer shielding layer 8 is for proof copper-wire braided forms, and outer jacket 8 is PVC sheath.
The utility model is by the outer increase semiconductive shielding layer 3 of insulating barrier 2 at every inner wire 1, anti-electromagnetic interference capability between inner two inner wires 1 of pair twist core group 9 is strengthened, every group of outer internal shield 4 that is all provided with of pair twist core group 9, antijamming capability between pair twist core group 9 is strengthened, again in conjunction with outer shielding layer 7, comprehensively improved the anti-electromagnetic interference capability of computer cable, simultaneously can also uniform electric field, make computer cable signal transmission more stable.By be disposed with waterproofing rope II 52 and waterstop 6 between outer shielding layer 7 and internal shield 4, between internal shield 4 and semiconductive shielding layer 3, fill waterproofing rope I 51, greatly improved the vertical and horizontal water-resisting ability of cable, and then improved the water repelling property of cable, make construction of cable rounding more simultaneously, Stability Analysis of Structures, not fragile.
Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the Single restriction condition to its technical scheme itself.
