Abstract: An arrangement allows the end of an electrical conductor (2) to be secured by clamping by a spring leaf (9) against a conductive connecting wall (6) in a compartment of a case of insulating material into which the end of the conductor is inserted. Arrangement includes at least one pushable member (10) for compressing the spring leaf, which penetrates the compartment in which the leaf is located and which is maneuverable from the outside of the case between two positions, one in which the spring leaf is relaxed and allows the end of a conductor to be freely inserted, the other in which the spring leaf is flexed by the urging of the pushing member and bears against the connecting wall.

Abstract: At least one terminal is provided comprising a screw (3) for securing wires and/or wire terminal lugs between a conducting wall of a connecting link (2) and a clamping plate (4) both traversed by the screw which also pulls together. Terminal is lodged in an insulating case (1) and comprises a screw retainer (1B4, 1B5) molded with the case and arranged to both guide the screw in its longitudinal travel between an open position in which the screw, the connecting link and the clamping plate leave open a passage from a wire ring-tongue terminal and a blocking position in which the clamping plate and the connecting link are brought together and retract the screw into an open position into the retainer by the latter's pressure against the bottom of the screw head.

Abstract: A terminal comprises a slotted bolt (7), and a cap (10) therefor. The cap has one end closed by a plate (14) with two lugs (11,12) projecting perpendicularly from the periphery of the plate (14) and a central boss (13) with two plane faces (18) opposite the gaps between the lugs. The plane faces have hooks (58) reaching part of the way up them, and the end of the boss beyond the hooks is polygonal.The tool includes a torque limiter (25), a casing (28), and a drive member (29) passing through the casing and made fast to the torque limiter. The casing has two lugs (44,45) and a lock (30) with hooks (39,39') that engage the hooks on the cap. The lugs on the casing fit in between the lugs on the cap, and the drive member has a sleeve (31) at its cap-engaging end with a socket (32) shaped to receive the central boss (13).
