6. The decoupling device according to claim 2 , wherein the actuator of the active part ( 40 ; 60 ) is triggered when a decoupling signal is received that is emitted by a control unit ( 70 ).
7. The decoupling device according to claim 3 , wherein the actuator of the active part ( 40 ; 60 ) is triggered when a decoupling signal is received that is emitted by a control unit ( 70 ).
8. The decoupling device according to claim 6 , wherein a connection between the control unit ( 70 ) and the decoupling device is a wireless connection.
9. The decoupling device according to claim 7 , wherein a connection between the control unit ( 70 ) and the decoupling device is a wireless connection.
10. The decoupling device according to claim 1 , wherein,
the passive part ( 30 ) comprises a ring mounted on the connector ( 10 ), the ring having a surface ( 31 ) delimiting bearing zones ( 32 , 33 ),
the active part ( 40 ) comprises a body ( 41 ) mounted on the socket ( 20 ) so as to grip the socket ( 20 ),
the body ( 41 ) comprises the plurality of rods forming the plungers, the plurality of rods being arranged at a periphery of the socket ( 20 ),
the plurality of rods being mounted translatably relative to the body ( 41 ),
the plurality of rods are set in motion, by the actuator ( 45 ) being triggered, to move in translation relative to an axis (B) of the socket ( 20 ) from a withdrawn position to a deployed position where an end of the plurality of rods protrudes past the collar ( 21 ) so that with the connector ( 10 ) being coupled to the socket ( 20 ), the end of the plurality rods come into contact with the bearing zones ( 32 , 33 ) of the surface ( 31 ) of the ring mounted on the connector ( 10 ) thereby applying a pressure on the bearing zones ( 32 , 33 ), the pressure on the bearing zones ( 32 , 33 ) providing the force which separates the connector ( 10 ) from the socket ( 20 ).
11. The decoupling device according to claim 1 , wherein,
the passive part ( 30 ) comprises a collar defining a periphery of a front face of the socket ( 20 ), the collar including a bearing surface,
the active part ( 60 ) comprises a body ( 61 ) forming a ring around the connector ( 10 ), the actuator ( 65 ) being secured to the body ( 61 ), the body ( 60 ) having a front surface ( 66 ),
the plurality of rods forming the plungers are mounted on the body ( 61 ) and are translatable along the axis (A) relative to the body ( 61 ), and
the plurality of rods are set in motion, by the actuator ( 65 ) being triggered, to move in translation relative to an axis (A) of the body ( 65 ) from a withdrawn position to a deployed position where an end of the plurality of rods protrudes past the front surface ( 66 ) of the body ( 60 ) so that with the connector ( 10 ) being coupled to the socket ( 20 ), the end of the plurality rods come into contact with the bearing surface of the collar thereby applying a pressure on the bearing surface, the pressure on the bearing surface providing the force which separates the connector ( 10 ) from the socket ( 20 ).
