Abstract
The utility model discloses a high-speed multimedia data cable. The high-speed multimedia data cable includes a 5 pairs of high frequency signal pairs used for data transmission, 4 pairs of control lines used for power transmission and signal control, and a cotton line. Each high frequency signal pair includes two copper wires which are each wrapped with a foaming layer. The foaming layer is provided with a plurality of hollow holes, and the volume of the plurality of hollow holes takes 40 to 60 percent of the volume of the entire foaming layer. A plastic-aluminum composite belt is wrapped at the surfaces of the 5 pairs of high frequency signal pairs, the 4 pairs of control lines, the cotton line and a current discharging line. A sheath layer is wrapped at the external surface of the plastic-aluminum composite belt. The sheath layer is a polyvinyl chloride layer or a polyurethane layer. The number of the cotton line is one, and the cotton line is located at the center part of the multimedia data cable. With the high-speed multimedia data cable, the influences of high frequency electromagnetic radiation and capacitance coupling on the cable are reduced, dielectric constant of an insulating layer is reduced, and capacitance is further reduced, so that transmission performance of the cable is improved and the measurement length requirement of 1.2 m is fulfilled.
Description
Technical field
The utility model relates to a kind of multi-medium data cable, relates in particular to a kind of high-speed multimedia data cable.
Background technology
The data cable structure of existing high-definition multimedia is to the control line with for electric power transfer and control signal transmission by the high-frequency signal for transfer of data, wrapped aluminium-plastic tape after the 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, for example conductor diameter is less than the high-definition multimedia data cable of 0.1mm, passing existing structure is the copper wire stranded conductor that uses 7 0.03mm, extrude perfluoroethylene-propylene (FEP) insulation at conductive surface, the insulated wire of two same sizes adds a drainage copper cash pair twist, online skin is wound around to one deck copper wire, then at winding copper wire skin, extrudes again one deck perfluoroethylene-propylene (copolymer) sheath and form high-frequency signal pair.The structure of control line is identical with the insulation core wire of high-frequency signal centering; Thereby form the high-definition multimedia data cable.
Although the density of covering that existing high-frequency signal 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 the above high band of 2.75GHz.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 client's big-length (more than 1m) requirement.Therefore, how to design a kind of data can effectively prevent leakage in the high-frequency signal transmitting procedure and different high-frequency signal between the cable of interference, become the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model provides a kind of high-speed multimedia data cable, this high-speed multimedia data cable can reduce the impact on cable of high frequency electromagnetic radiation and capacitive coupling, and reduce the dielectric constant of insulating barrier, thereby and then reach and reduce electric capacity and improve the transmission performance of cable, and met the requirement of 1.2m testing length.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-speed multimedia data cable, comprise: the 5 pairs of high-frequency signals for transfer of data are to, the 4 pairs of control lines for electric power transfer and signal controlling and cotton thread, described high-frequency signal is to comprising two copper conductors that are covered with foaming layer outward, if this foaming layer has individual cavity, if the volume in this individual cavity accounts for 40 ~ 60% of whole foaming layer volume;
One aluminium-plastic tape wrapped in 5 pairs of described high-frequency signals to, 4 pairs of control lines, cotton thread and drain wire surfaces;
One restrictive coating is coated on described aluminium-plastic tape outer surface.
In technique scheme, further improved technical scheme is as follows:
1,, in such scheme, described restrictive coating is polyvinyl chloride layer or layer of polyurethane.
2,, in such scheme, described cotton thread 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 high-speed multimedia data cable, its high-frequency signal is to comprising two copper conductors that are covered with foaming layer outward, if this foaming layer has individual cavity, if the volume in this individual cavity accounts for 40 ~ 60% of whole foaming layer volume, can reduce the impact on cable of high frequency electromagnetic radiation and capacitive coupling, and reduce the dielectric constant of insulating barrier, thereby and then reach and reduce electric capacity and improve the transmission performance of cable, and met the requirement of 1.2m testing length.
