Hydraulic tool for uncoupling a connection assembly, in particular with multi-contact connectors

A tool for uncoupling a connection assembly which comprises a first connector, in particular a multi-contact connector comprising hooking reliefs, and a second connector, in particular a multi-contact connector, of a type that complements the first connector, the second connector forming a receptacle designed to be fastened to a panel, the first and second connectors each comprising a housing extending along an axis and comprising a connection face, the first and second connectors being connected together via their connection faces,

• the tool comprising:
• at least one hook comprising at least one hooking relief designed to interact by hooking to a hooking relief of the first housing and a locking tip;
• a hydraulic circuit comprising at least one cylinder, at least one piston called main piston forming, together with the cylinder, a master cylinder, at least one conduit connecting the main piston to at least one secondary piston, in which the hydraulic circuit is actuated once the hooking of at least one relief of the first housing via the hooking relief of the hook has been achieved, thereby giving rise to the movement of the main piston that transmits the pressure of the hydraulic fluid toward the at least one secondary piston that shifts from an inactive position, in which the at least one secondary piston is locked by the locking tip until the hooking of the relief of the first housing has been achieved, to an active position, in which the at least one secondary piston is unlocked and is able thus to exert a thrust force against the panel to which the receptacle is fastened, in such a manner as to achieve the uncoupling/disconnection between the receptacle and the first connector,
• wherein each hook is mounted so as to pivot between a locking position, in which the locking tip locks the secondary piston in its the inactive position, and a hooking position, in which the hooking relief hooks the hooking relief of the first housing whilst, simultaneously, the tip is unlocked from the secondary piston.
