Signal transmission line for display

Abstract

The invention relates to the transmission of signals, in particular to a cable for connecting a PC (Personal Computer) host with RGB (Red, Green, Blue) signal wires of a display, a monitor and other display devices. the cable comprises four core wires coated with insulating layers and five power lines and is characterized in that each core line coated with the insulating layer is coated with an inner shielding layer after being combined with a grounding wire, the inner shielding layer is made of single-sided aluminum foil Mylar, the four core wires coated with the inner shielding layer, the grounding wire and the five power lines form a wire harness which is coated with an aluminum foil and conductive metal wire braid layer, and a jacket is arranged outside the braid layer. The invention has the advantages of convenience for operation, simple structure, high production efficiency, more stability for signal transmission, high speed for signal transmission, good quality for signal transmission and the like.

[0002] As we all know, with the development of science and technology, there are more and more occasions for application signal transmission, especially scientific research, medical equipment and other display devices have higher and higher requirements for signal transmission speed and signal transmission quality. The existing RGB The signal transmission line is composed of four sets of coaxial lines and five power lines to form a wiring harness. Aluminum foil and conductive metal wire are used as the outer shielding layer outside the wiring harness. There is a PVC sheath on the outer shielding. The inner shielding layer is braided with conductive metal wires. The disadvantages of the above-mentioned prior art are that the processing procedures are cumbersome, the production cycle is long, the cost is high, the transmission speed is slow, and the signal transmission effect is poor.
