Description
Technical Field
The utility model relates to a cable technical field especially relates to a shielded wire for touch display screen.
Background
With the rapid development of economy and society, the occupancy rate of touch digital televisions in common household users is higher and higher. The touch data line is a wire for transmitting a touch-sensitive multimedia video signal. The touch data line can transmit uncompressed touch video and multi-channel audio data with high quality. Meanwhile, the digital-to-analog or analog-to-digital conversion is not needed before signal transmission, and the transmission of the video-audio signal with the highest quality can be ensured. However, the existing touch data cable has poor data shielding effect and is easy to be interfered, and the transmission performance is influenced.
For example, chinese patent document CN201520324899.2 discloses a touch data cable, which includes a touch data cable, and includes four groups of twisted-pair cables and an outer protective layer sleeved on the periphery of the four groups of twisted-pair cables, each group of twisted-pair cables includes two twisted-pair cables, a shielding layer is sleeved on the periphery of the two twisted-pair cables, a ground wire is disposed between the shielding layer and the two twisted-pair cables, and seven wires are further sleeved on the inner side of the outer protective layer.
Although the above solution can shield part of the interference, it still cannot meet the needs of people.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem, provide a reasonable in design, interference immunity is strong for touch display screen's shielded wire.
The utility model provides a shielded wire for touch display screen, includes restrictive coating, weaving layer and the aluminium foil layer that sets gradually from outer to interior, be provided with four sinle silks in the aluminium foil layer, the sinle silk comprises the copper conductor that has the PVC insulating layer of covering outward, wherein two the sinle silk is twisted each other and is formed a hank to the line, the sinle silk with it has the cotton rope to fill between the hank to the line.
In one embodiment, the sheath layer is embedded with uniformly distributed reinforcing ribs.
In one embodiment, the twisted pair wires are clad with a double-sided aluminum foil layer.
According to the shielding wire for the touch display screen, the strength of the cable is improved through the arrangement of the reinforcing ribs, external force is released under the action of the shock absorption layer, the interior of the cable is protected, the service life is prolonged, external electromagnetic waves are absorbed and shielded under the action of the anti-interference shielding layer and the protective layer, the interference of the electromagnetic waves is reduced, and the transmission effect of the cable is improved; the aluminum foil layer has good wave absorbing performance, is convenient for shielding electromagnetic waves, reduces the influence of the electromagnetic waves and effectively reduces the influence of the external environment on the cable; the second twisted pair wire is externally coated with double-sided aluminum foil layers, and mutual interference among different signals in the signal transmission process can be avoided.
