Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a charging cable for an unmanned aerial vehicle. Background Art

[0002] Drones are widely used in people's lives and production and manufacturing. Their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the uses of drones themselves.

[0003] Conventionally, drones are equipped with batteries that need to be charged before use. Especially for some drones used in agriculture and transportation, the batteries are required to have large capacity and high power.

[0004] Correspondingly, the charging cable of the drone will generate high temperature during the charging process, and the charging cable needs to be used frequently and the environment in which it is used is also relatively harsh.

[0005] Therefore, during the charging process, the charging cables of existing drones are prone to overheating, which may cause the cables to burn out. In addition, frequent use may cause the cables to bend and deform, resulting in cable failure or dangerous accidents such as electric shock. Utility Model Content

To this end, the utility model proposes a drone charging cable, which can reduce the problem of cable breakage and deformation caused by cable bending during use and improve high temperature resistance.

[0007] According to an embodiment of the utility model, a drone charging cable comprises an electric energy transmission line, a signal transmission line and an outer sheath, wherein the electric energy transmission line and the signal transmission line are covered by the outer sheath; the electric energy transmission line comprises a first conductor and a first silicone sleeve, and the outer surface of the first conductor is sleeved with the first silicone sleeve; the signal transmission line comprises a core wire and a second silicone sleeve, the core wire is arranged in the second silicone sleeve, the core wire comprises a second conductor, a bulletproof wire and an insulating sleeve, the second conductor and the bulletproof wire are twisted together, and the second conductor and the bulletproof wire are arranged inside the insulating sleeve.

[0010] 2. The utility model provides a second conductor, a bulletproof wire, an insulating sleeve and a second silicone sleeve.

The good toughness of the bulletproof wire is utilized to greatly improve the toughness of the signal line, so that the signal transmission line is not easy to break and the service life of the signal transmission line is increased. The insulating sleeve is utilized to isolate the signal line from the outside and improve the insulation performance of the signal line. In addition, the second silicone sleeve makes the signal line softer and more resistant to high temperatures.

[0011] According to some embodiments of the present invention, the signal transmission line further includes an aluminum foil tape, which is wound around the outer surface of the insulating sleeve.
