Semi-pantograph disconnector

A semi-pantograph disconnector, comprising - a base (11), which supports a motor kinematic system (12), - an arm (13), which has a shoe (14) for gripping a dropper (15) and is hinged to the base (11) so as to be able to oscillate in order to pass reversibly from a disconnection configuration, in which the arm (13) is collapsed onto the base (11), to a contact configuration, in which the arm (13) is divaricated from the base (11) so as to connect by means of the shoe (14) to the dropper (15), - a rod (16), which is functionally connected to the shoe (14) in order to actuate it, - a cam device (17) for actuating the rod (16), which coordinates kinematically the opening of the shoe (14) and a first rotation of the arm (13) from the disconnection configuration to the contact configuration, - a semi-pantograph device (18), which is functionally connected to the rod (16), to the arm (13) and to the motor kinematic system (12), defining a kinematic sequence for closing the shoe (14), after the first rotation of the
