Description
Technical field
The utility model relates to a kind of data cable, particularly relates to a kind of anti-interference data cable.
Background technology
The data cable structure of existing high-definition multimedia be by for transfer of data high-frequency signal line to the control line transmitted for electric power transfer and control signal, wrapped aluminium-plastic tape after set stranding, the outer proof copper-wire braided that covers shields again, finally extrudes one deck restrictive coating and forms finished product.For small dimension, such as conductor diameter is less than the high-definition multimedia data cable of 0.1mm, pass the copper wire stranded conductor that existing structure is use 7 0.03mm, perfluoroethylene-propylene (FEP) insulation is extruded at conductive surface, the insulated wire of two same sizes adds a drainage copper cash pair twist, online one deck copper wire is wound around to skin, then extrudes one deck perfluoroethylene-propylene (copolymer) sheath again at winding copper wire skin and form high-frequency signal line pair.The structure of control line is identical with the insulation core wire of high-frequency signal line centering; Thus composition high-definition multimedia data cable.
Although the density of covering that existing high-frequency signal line centering copper wire is wound around shielding is greater than 99%, the leakage when high-frequency signal transmits is still very serious, especially especially serious in the decay of more than 2.75GHz high band.The small dimension multimedia data cable of 7 0.03mm copper wires as described above, its transmission length only has 0.5m, can not meet large length (more than the 1m) requirement of client.Therefore, how to design a kind of data can effectively prevent the leakage in high-frequency signal transmitting procedure and different high-frequency signal line between the cable of interference, become the direction that those of ordinary skill in the art make great efforts.
Summary of the invention
The utility model provides a kind of anti-interference data cable, this data cable effectively reduces the impact of external environment on cable, effectively prevent the leakage in high-frequency signal transmitting procedure and different high-frequency signal line between interference, and effectively prevent glare problem, further increase the disguise of data cable and communication equipment.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-interference data cable, comprise one for transfer of data high-frequency signal line to and drain wire, this high-frequency signal line forms the copper conductor being covered with insulating barrier outward by two;
Be overlying on outside one aluminium-plastic tape high-frequency signal line to drain wire outer surface;
One inner restrictive coating is coated on described aluminium-plastic tape outer surface;
One transparent external sheath layer is coated on described inner restrictive coating outer surface, is evenly distributed with some pores in this transparent external sheath layer;
One wire braid is between described inner restrictive coating and transparent external sheath layer.
The technical scheme improved further in technique scheme is as follows:
In such scheme, described transparent external sheath layer is transparent polyvinyl chloride layer or transparent polyurethane layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The anti-interference data cable of the utility model, wire braid is provided with between its inner restrictive coating and transparent external sheath layer, effectively reduce the impact of external environment on cable, the screening rate of 100% can be formed, and also prevent the leakage in high-frequency signal transmitting procedure and different high-frequency signal line between interference, and meet the requirement of 1.2m testing length; Secondly, its inner restrictive coating is coated on described aluminium-plastic tape outer surface, one transparent external sheath layer is coated on described inner restrictive coating outer surface, some pores are evenly distributed with in this transparent external sheath layer, diffuse reflection can be formed on surface when light, effectively prevent glare problem, further increase the disguise of data cable and communication equipment.
