Problems solved by technology

However, due to the limitation of foreign procurement and the lagging development of domestic enterprises, the research and development of digital video cables required for military equipment is still blank
The industrial-grade digital video cables currently widely used have the following obvious shortcomings: ① Digital video signals and power signals cannot be transmitted at the same time; ② Poor signal environment adaptability and poor anti-interference ability of transmission; ③ No hot-swappable function; ④The cable interface is too large and the wiring harness is thick and hard, which is not suitable for system integration

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0013] as figure 1 As shown, the digital video cable provided by the preferred example of the present invention includes two first and second connectors a and wire b with identical structures.

[0014] according to figure 2 As shown, connector a adopts miniaturized military micro-rectangular connector. The connector contains a metal shell, n video pins 2~6, 10~14, m chip ground pins 1, 9, 15, two power pins 7, 8, airtight rubber, two locking screws, n It is an even number and n≥2, m depends on the number of video chip ground signals used in the optoelectronic system; n video pins are equal to the length of m chip ground pins; the length of the two power pins is shorter than other pins; the pin arrangement depends on the optoelectronic The electrical interface arrangement of the system. In this preferred embodiment, n=10, m=3, fi...

Abstract

The invention discloses a digital video cable suitable for an unmanned plane optoelectronic system and belongs to the field of electrical connection. The digital video cable suitable for the unmanned plane optoelectronic system comprises two connectors and a wire group and is characterized in that the length of a power source pin of each connector is smaller than those of other pins, the wire is composed of a plurality of double-twisted shielding wires and a double-twisted wire, the double-twisted shielding wires are placed in parallel to the double-twisted wire after being coated with an insulating layer, and the double-twisted shielding wires and the double-twisted wire are finally coated with a metal shielding net layer. The digital video cable suitable for the unmanned plane optoelectronic system achieves the purpose that high-frequency digital video signals and power signals are transmitted together in the optoelectronic system and has the function of hot plugging and the advantages of being simple in structure, high in safety, good in environmental suitability, capable of being used in the unmanned plane optoelectronic system and other imaging devices of the same type and the like.

Description

technical field [0001] The invention relates to a cable, mainly to a digital video cable, in particular to a cable suitable for the common transmission of a digital video signal and a power signal in an optoelectronic system of an unmanned aerial vehicle. Background technique [0002] For UAV optoelectronic systems, whether it is reconnaissance or strike weapons and equipment, the real-time acquisition of images of the target area is particularly important. With the development of weapons and equipment, the traditional analog video signal system can no longer meet the needs of high-resolution imaging and high-speed image processing. Digital video can realize high-resolution image transmission, has a large amount of information, strong anti-interference ability, and rich signal processing methods. It is gradually becoming an important technical indicator for military project demonstration. At present, many model projects have required the photoelectric system to have digital...
