Abstract
The utility model provides a kind of cable of high frequency transmission signal, comprise one for the high-frequency signal pair of transfer of data, high-frequency signal to the copper conductor being covered with insulating barrier outward by two and and the parallel earth lead of copper conductor form, the external coated plastic-aluminum composite bed of high-frequency signal, earth lead and plastic-aluminum combined layer inner surface in electrical contact, avoid the electromagnetic wave roundtrip in signal transmission cable and form induced potential, decrease and interference is caused to self transmission signal, also can effectively prevent electromagnetic radiation from causing the electromagnetic interference to external equipment to outward leakage simultaneously, especially at high frequency, in ultra-high-frequency data transmission, shield effectiveness is also ideal, at plastic-aluminum combined layer outer cladding metal mesh shield layer, nonwoven fabrics lapping layer is set outside metal mesh shield layer, outside nonwoven fabrics lapping layer, arrange restrictive coating, plastic-aluminum combined layer makes this cable have good anti-interference function, and it all has good anti-jamming effectiveness to low frequency or High-frequency Interference.
Description
Technical field
The utility model relates to the communications field, particularly relates to a kind of cable of high frequency transmission signal.
Background technology
Existing generally all have screen as the cable of high frequency transmission signal on the market, but screen mostly generally is individual layer, the scope of its signal shielding is narrower, shield effectiveness is not good, the interference simultaneously shielding high and low frequency signal can not be realized, also there is interference mutually between different high-frequency signal, high-frequency signal is gone back ubiquity and is caused leakage problem in transmitting procedure simultaneously.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides that shield effectiveness is good, signal not easily leaks in transmitting procedure, the cable of the high frequency transmission signal of noiseless existence between signal.
The utility model is achieved in that a kind of cable of high frequency transmission signal, comprise one for the high-frequency signal pair of transfer of data, described high-frequency signal to the copper conductor being covered with insulating barrier outward by two and and the parallel earth lead of copper conductor form, the external coated plastic-aluminum composite bed of described high-frequency signal, described earth lead and described plastic-aluminum combined layer inner surface in electrical contact, at described plastic-aluminum combined layer outer cladding metal mesh shield layer, nonwoven fabrics lapping layer is set outside described metal mesh shield layer, restrictive coating is set outside described nonwoven fabrics lapping layer.
Further, described restrictive coating is polyvinyl chloride layer or layer of polyurethane.
Further, described metal mesh shield layer is tin copper composite film layer.
Further, the thickness of described metal mesh shield layer is 0.2mm-4.0mm.
The utility model provides a kind of cable of high frequency transmission signal, comprise one for the high-frequency signal pair of transfer of data, described high-frequency signal to the copper conductor being covered with insulating barrier outward by two and and the parallel earth lead of copper conductor form, the external coated plastic-aluminum composite bed of described high-frequency signal, described earth lead and described plastic-aluminum combined layer inner surface in electrical contact, avoid the electromagnetic wave roundtrip in signal transmission cable and form induced potential, decrease and interference is caused to self transmission signal, also can effectively prevent electromagnetic radiation from causing the electromagnetic interference to external equipment to outward leakage simultaneously, especially at high frequency, in ultra-high-frequency data transmission, shield effectiveness is also ideal, at described plastic-aluminum combined layer outer cladding metal mesh shield layer, outside described metal mesh shield layer, nonwoven fabrics lapping layer is set, outside described nonwoven fabrics lapping layer, restrictive coating is set, plastic-aluminum combined layer makes this cable have good anti-interference function, and it all has good anti-jamming effectiveness to low frequency or High-frequency Interference, meanwhile, external sheath layer makes cable have good anti-aging, anti-hydrolytic performance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The cable structure schematic diagram of the high frequency transmission signal that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, the utility model embodiment provides a kind of cable 1 of high frequency transmission signal, comprise one for the high-frequency signal of transfer of data to 11, described high-frequency signal to 11 by two copper conductors 111 being covered with insulating barrier outward and and the parallel earth lead 112 of copper conductor form, described high-frequency signal is to the plastic-aluminum combined layer 12 of 11 outer cladding, described earth lead 112 is in electrical contact with described plastic-aluminum combined layer 12 inner surface, avoid the electromagnetic wave roundtrip in signal transmission cable and form induced potential, decrease and interference is caused to self transmission signal, also can effectively prevent electromagnetic radiation from causing the electromagnetic interference to external equipment to outward leakage simultaneously, especially at high frequency, in ultra-high-frequency data transmission, shield effectiveness is also ideal, at described plastic-aluminum combined layer 12 outer cladding metal mesh shield layer 13, outside described metal mesh shield layer 13, nonwoven fabrics lapping layer 14 is set, outside described nonwoven fabrics lapping layer 14, restrictive coating 15 is set, plastic-aluminum combined layer 12 makes this cable 1 have good anti-interference function, and it all has good anti-jamming effectiveness to low frequency or High-frequency Interference, meanwhile, external sheath layer 15 makes cable 1 have good anti-aging, anti-hydrolytic performance.
In embody rule, as Fig. 1, described metal mesh shield layer 13 is tin copper composite film layer; Further, the thickness of described metal mesh shield layer 13 is 0.2mm-4.0mm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
