Abstract: A terminal for connecting an electrical conductor to a connection pad of a device, the terminal including a cage to be fixed inside the housing of the device and including an orifice of substantially parallelepipedal shape and delimited by four walls, the orifice being able to receive the pad, an upper wall including an orifice able to allow the passage of a screw with an actuator and a clamping shoe able to allow the conductor to be clamped between the pad and the shoe upon actuation of the screw driving the relative translational movement between the screw and the cage. Terminal includes an intermediate stage inside the cage to allow the reception of a nut with elastic branches having a threaded orifice through which the clamping screw is to be mounted, the elastic branches interacting with forms provided on the side walls of the cage such that the nut rotationally disengages as soon as the correct clamping torque is reached.

Abstract: An item for tightening including a first part including a first end part forming an end piece to engage with the head of a screw, and a second end part to engage with an actuating member, such that activation of the actuating member causes turning of the screw and the tightening, this first part being able to break into two portions upon reaching the recommended tightening torque, respectively a first portion including the first end part and a second portion including the second end part. A second part is mounted tightly about the first part, a holding device is provided in part on the first part and in part on the second part and being able to retain the second portion of the first part inside the second part of the item in order to prevent this second portion leaving this second part of the item after rupture of the first part.

Abstract: The invention relates to a flexible tunnel for connection terminal, made by cutting and bending a metal strip to form a flexible frame delimiting an opening. Said opening is delimited by a first and a second lateral branch extending parallel to one another from a bottom, the first branch being extended by an upper branch closing the one-piece structure of the tunnel. When the tunnel is in an untightened state, the upper branch through which the clamping screw is intended to pass in a perpendicular manner forms a first angle of deformation with a longitudinal axis of the tunnel parallel to the first and second lateral branches. The bottom forms a second angle of deformation with the longitudinal axis of the tunnel.

Abstract: The invention relates to a flexible tunnel for connection terminal, made by cutting and bending a metal strip to form a flexible frame delimiting an opening (18). Said opening is delimited by a first and a second lateral branch (22, 24) extending parallel to one another from a bottom (20), the first branch (24) being extended by an upper branch (26) closing the one-piece structure of the tunnel (12). When the tunnel (12) is in an untightened state, the upper branch (26) through which the clamping screw (14) is intended to pass in a perpendicular manner forms a first angle of deformation (?1) with a longitudinal axis of the tunnel (12) parallel to the first and second lateral branches (22, 24). The bottom (2) forms a second angle of deformation (?2) with the longitudinal axis of the tunnel (12).

Abstract: The present invention relates to a connection terminal for an electrical switchgear apparatus, designed to prevent incorrect connection of a cable.This terminal comprises a tunnel, a contact pad and a tightening screw. At its lower part, the tunnel is provided with two protuberances arranged to cooperate with two flexible hooks of a shield. This shield is formed by a rigid plate which can be securedly affixed to the tunnel to partially mask the opening of the tunnel when an electrical wire or cable of small diameter is connected.The fit-on shield is advantageous in that it enables all conditions of use to be met.

Abstract: The invention relates to a fast closing mechanism of a circuit breaker with an operating handle.The mechanism comprises an energy storage spring disposed between the handle and an intermediate lever supporting a transmission rod. A retaining plate operates in conjunction with a pin of the handle to occupy either an active position locking the rod during loading of the spring, or a retracted position unlocking the rod allowing the spring to be released at the end of closing travel.
