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. <EOS>
