Description

Video signal transmission cable with high anti-interference performance

Technical Field

The utility model relates to a transmission cable technical field specifically is a video signal transmission cable with high anti-interference.

Background

The transmission cable, VGA (Video Graphics Array) cable, includes the VGA interface and the connected cable, but is usually referred to as VGA interface, also called D-Sub interface. VGA can support much higher resolution than high definition. Therefore, command centers (such as military police and television stations) of various large projects and various large institutions all adopt VGA technology to transmit ultrahigh-definition large-screen images.

However, the existing transmission cable is generally short in length, and transmission cables with the length of more than one hundred meters often have the problems of poor anti-jamming capability, low resolution and unstable transmission signals. For this reason, there is a video signal transmission cable having high interference resistance.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a video signal transmission cable with high anti-jamming has solved the problem of proposing in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a video signal transmission cable with high anti-interference, includes from outside to inside in proper order the first PVC layer of cladding, first tinned tube weaving layer, second PVC layer, second tinned tube weaving layer and wheat draw the layer, wheat is drawn the in situ and is provided with three first wires, five second wires and two sets of wire group, three first wire is "article" style of calligraphy and arranges, and wherein three second wires are located between three first wires, and two other second wires are located three first wire downside, and are two sets of the wire group is located three first wire both sides respectively.

Preferably, the first lead comprises a tin-plated copper shaft body, and a foamed PE, a tin-plated copper layer and a low-smoke halogen-free material layer which are sequentially coated on the outer side of the circumference of the tin-plated copper from inside to outside.

Preferably, the second lead comprises a tin-copper axial line body and an SR-PVC layer coated outside the circumference of the tin-plated copper.

Preferably, the lead group comprises a tin-plated copper outer layer and two third leads arranged in the tin-plated copper outer layer, and the third leads comprise tin-plated copper and an HD-PE layer arranged outside the circumference of the tin-plated copper.

Preferably, cotton threads are arranged on the upper side and the lower side of each wire group.

Preferably, a nylon wire is embedded in the first PVC layer.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a set up first PVC layer, first tinned tube weaving layer, second PVC layer, second tinned tube weaving layer, wheat and draw the layer and set up at three intraformational first wires, five second wires and two sets of wire groups of wheat, arrange through its structure, make the cable possess high anti-interference, high resolution and the stable advantage of signal transmission simultaneously, and the longest service length of cable can reach 150 meters.
