High-performance Germany-standard vehicle reversing video cable

Abstract

The invention discloses a high-performance Germany-standard vehicle reversing video cable. The cable comprises a cable core, wherein the cable core is formed by twisting a data transmission cable and two power lines that are arranged in parallel up and down; a conductive PVC middle covering layer, a first shielding layer woven by an aluminium foil or copper, a tin-plated layer and an outer covering layer are arranged on the exterior of the cable core in sequence, wherein the data transmission cable comprises a cable core formed by two data lines and a ground wire, wherein the two data lines are arranged in parallel up and down and are twisted in pairs; and a second shielding layer woven by the aluminium foil or copper is directly arranged on the exterior of the cable core. According to the high-performance Germany-standard vehicle reversing video cable, the transmission length of the stranded wire is prolonged; a 100% shielding effect on the shielding layer is achieved, and the cable transmission precision and quality are improved; and meanwhile, the tin component is soft metal, so that the cable is suitable for use and deep processing.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a high-performance German standard car reversing video cable. Background technique [0002] Existing technology applications, the current car reversing video cables are transmitted using the following two structures, the first is a single-core coaxial cable plus two power lines, the shielding adopts a braided structure, and the outermost layer is a sheath; the second is A pair of twisted core wires plus two power wires, the shielding adopts a braided structure, and the outermost layer is a jacket. [0003] The above two cables have different defects. The first product structure adopts the coaxial structure, and the coaxial cable transmits analog signals. Although the transmission distance of this type of signal is long, the resolution is low, which cannot meet the current requirements of GPS for high-end cars. Resolution, the highest resolution of this type of product is 1280×720...

Problems solved by technology

[0003] The above two cables have different defects. The first product structure adopts the coaxial structure, and the coaxial cable transmits analog signals. Although the transmission distance of this type of signal is long, the resolution is low, which cannot meet the current requirements of GPS for high-end cars. resolution, the highest resolution of this type of product is 1280×720, so the first design will soon be out of the market

The second product structure adopts the differential digital transmission method. The resolution of this method can reach 1080P, and the current maximum can reach 4K. However, due to the short transmission distance of this type of design, it can reach 10 meters without external magnetic field interference, and the video delay of more than 10 meters Increase, the length of the car reversing video cable is 8 to 10 meters. Under the interference of the magnetic field of the car, the braided shielding is used for grounding. The shielding effect can only reach 90% of the shielding. The shielding has not been able to achieve 100% shielding, so the transmission distance has always been Restricted
