Claim 0:
1. A connection between a wired drone and a wire of the drone, the connection comprising:
—a socket on the wire and a header on the drone, the socket and the header being configured to provide at least one power supply to the drone and a recovery of mechanical forces between the drone and the wire, the socket being remotely detachable, while the drone is in flight, a ground base being configured to feed the wire,
—a protection device comprising:
a) a non-conductive sheath which encloses electrical contacts of the socket, a geometry of the non-conductive sheath limiting any contact between a person and the electrical contacts,
b) a mechanical system configured to cut off a supply current at the ground base, so that an assembly of the wire and the electrical contacts of the socket are powered off,
c) a system for mechanical protection of the socket against shocks, taking at least one of the following three forms:
i) a sheath dissipating a mechanical energy, comprising rubber studs or fins;
ii) a system for slowing down the fall of the socket, such as a parachute, opening automatically when disconnecting the socket from the drone,
iii) separation of the socket into several sub-parts connected by one or more flexible elements.
