Terminal for connecting an electrical conductor to the connection pad of an electrical device, and electrical protection device including such a terminal

A terminal for connecting an electrical conductor to a connection pad belonging to an electrical device, such a terminal comprising a cage able to be fixed inside the housing of the electrical device and including an orifice of substantially parallelepipedal form and delimited by four walls, said orifice being able to receive said pad, one of said walls of the cage, called upper wall, including an orifice able to allow the passage of a screw, said screw including, at one of its ends situated outside the cage, means for actuating said screw, and, at its opposite end, a clamping shoe able to allow the conductor to be clamped between said pad and said shoe upon actuation of the screw driving the relative translational movement between the screw and the cage,

• wherein an intermediate stage created inside the cage so as to allow the reception of a nut with elastic branches having a threaded orifice through which the clamping screw is to be mounted in a screwed manner, said elastic branches interacting with forms provided on the side walls of the cage such that the nut rotationally disengages upon the screwing as soon as the correct clamping torque is reached, and engages from the start to the end of the unscrewing.
