A disconnector, particularly of the double-break double-movement type, comprising:–a crossmember (11), which has the contact pins (12) at its opposite ends;–C-shaped contact sockets (13), which are aligned so as to correspond to the pins (12) in order to receive them by insertion, along a trajectory that is circumferential with respect to a first rotation axis (A) of the crossmember (11), which is substantially transverse thereto;–a support (14) of the crossmember (11) that defines for it the first rotation axis (A), and a second rotation axis (B), which is substantially longitudinal to the crossmember (1);–means (15) for the rotation of the crossmember (11) about the first rotation axis (A) in order to drive the transition of the pins (12) from a disengagement configuration to an engagement configuration in the sockets (13) and vice versa, and about the second rotation axis (B) in order to drive the transition of the pins (12) from an uncoupling configuration to a coupling configuration of moving contacts (16) of the pins (12) with fixed contacts (17) of the sockets (13), and vice versa. The fixed contacts (17) are connected electrically, in two separate regions (18a, 18b), to supporting arms (20a, 20b) that belong to the sockets (13), and have a portion (19) that is intermediate with respect to the two regions (18a, 18b), is adapted for contact with the moving contacts (16), and divides the fixed contacts (17) into two opposite conducting arms (21a, 21b) adapted to conduct electrical currents having a substantially equal intensity. |
