Although the density of covering of copper wire winding shielding is greater than 99% in existing high-frequency signal line, 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 the cable that a kind of data effectively can prevent the leakage in high-frequency signal transmitting procedure and the interference between different high-frequency signal line, 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 shield type communication data cable, this communication data cable prevents the leakage in high-frequency signal transmitting procedure and the interference between different high-frequency signal line, 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 shield type communication data cable, comprise: 5 to the high-frequency signal line, 4 for transfer of data to for the control line of electric power transfer and signal controlling and cotton thread gasket for packing, described high-frequency signal line comprises copper conductor and the drain wire that two are covered with insulating barrier outward, one compound copper-plastics band is coated on described copper conductor and described drain wire surface, and by laminated polyester film and plating, the layers of copper in this laminated polyester film surface forms this compound copper-plastics band;
One aluminium-plastic tape wrapped in 5 to described high-frequency signal line, 4 pairs of control lines, cotton thread gasket for packing and drain wires 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, and this transparent external sheath layer inner surface is evenly distributed with several depressed parts;
One proof copper-wire braided layer is between described inner restrictive coating and transparent external sheath layer.
The technical scheme improved further in technique scheme is as follows:
1, in such scheme, described layers of copper is positioned at the inner side of compound copper-plastics band and contacts with drain wire.
2, in such scheme, described transparent external sheath layer is transparent polyvinyl chloride layer or transparent polyurethane layer.
3, in such scheme, described cotton thread gasket for packing number is 1 and is positioned at the center of described multi-medium data cable.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model shield type communication data cable, 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 the interference between different high-frequency signal line, 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, this transparent external sheath layer inner surface is evenly distributed with several depressed parts, diffuse reflection can be formed on surface when light, effectively prevent glare problem, further increase the disguise of data cable and communication equipment.
