Description

Technical Field

[0002] With the development and progress of science and technology, more and more advanced equipment has been developed and continuously innovated and improved. In the military field, military drones occupy a very important position and play an indispensable role.

[0003] Military UAVs are unmanned aircraft controlled by remote control equipment or self-provided programs. According to their control methods, they are mainly divided into three types: radio remote control, automatic program control and integrated control. With the widespread application of high-tech in weapons and equipment, the development of military UAVs has made breakthrough progress. Military UAVs can achieve beyond-visual-range communication, radar reconnaissance, radio reconnaissance, surveillance, strike, communication relay and other tasks. Military UAVs have high value and good development prospects.

[0004] At present, the data cables used for military drones generally include a core, a shielding layer, an insulating layer and an outer sheath. The shielding layer, the insulating layer and the outer sheath are sequentially coated on the outside of the multiple cores. The shielding layer, the insulating layer and the outer sheath are usually single-layer structures. Although the structure of this data cable is relatively simple and can basically realize the transmission function of electrical signals, its function is relatively single. Due to the unreasonable structural design, the waterproof performance is poor and cannot meet the current high requirements for waterproof performance; and the shielding performance of the data cable is general, which affects the signal transmission quality and the user experience is poor; the data cable is not resistant to high temperature. When used in a high temperature environment, the performance of the data cable decreases, affecting the normal transmission of the signal, and the service life is short, which brings inconvenience to the user and cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to improve the current military drone data cable. Utility Model Content

In the present embodiment, the second shielding layer 112 is made of metal foil material and has good shielding performance.

[0035] The waterproof layer 12 covers the eight wires 11 and waterproof glue 17 is filled between the waterproof layer 12 and the eight wires 11; in the present embodiment, the waterproof layer 12 is a TPO waterproof material, which is also called a thermoplastic polyolefin waterproof material, and has the comprehensive characteristics of excellent waterproof performance, high tensile strength, strong UV resistance, smooth surface, high reflectivity, etc., and is easy to process, green and environmentally friendly, and non-toxic and harmless.
