Description

Technical Field

[0001] The utility model relates to an automatic wire detachment device, in particular to an automatic wire detachment device for an unmanned aerial vehicle (UAV) used for on-board launching. Background Art

[0002] In order for the engine installed in a related UAV to achieve maximum performance, the internal space layout and functional design often discard relatively bulky, short-lived components that are not conducive to maximizing the engine performance for autonomous startup. The commonly adopted solution in the industry is to use an external power supply module to complete the autonomous startup of the engine before the UAV is launched. After the engine runs stably, the external power supply module is removed to complete the launch of the UAV.

[0003] The connector form generally adopted for the electrical connection between a related external power supply module and the UAV is an aviation plug. The related aviation plug can stably and reliably complete the electrical connection between the external power supply module and the UAV.
