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 the 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, the geometry of the sheath limiting any contact between a person and the electrical contacts, b) a mechanical system configured to cut off the supply current at the ground base, so that the 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, consisting of rubber studs or fins; ii) a system for slowing down the fall, such as a parachute, opening automatically when disconnecting the socket from the drone, iii) the separation of the socket into several sub-parts connected by one or more flexible elements. - 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 the 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, the geometry of the sheath limiting any contact between a person and the electrical contacts, b) a mechanical system configured to cut off the supply current at the ground base, so that the 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, consisting of rubber studs or fins; ii) a system for slowing down the fall, such as a parachute, opening automatically when disconnecting the socket from the drone, iii) the separation of the socket into several sub-parts connected by one or more flexible elements. a) a non-conductive sheath which encloses electrical contacts of the socket, the geometry of the sheath limiting any contact between a person and the electrical contacts, b) a mechanical system configured to cut off the supply current at the ground base, so that the 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, consisting of rubber studs or fins; ii) a system for slowing down the fall, such as a parachute, opening automatically when disconnecting the socket from the drone, iii) the separation of the socket into several sub-parts connected by one or more flexible elements. i) a sheath dissipating a mechanical energy, consisting of rubber studs or fins; ii) a system for slowing down the fall, such as a parachute, opening automatically when disconnecting the socket from the drone, iii) the separation of the socket into several sub-parts connected by one or more flexible elements.
