Embodiment Construction

[0028] In the drawing, it can be seen that the electrical terminal B is housed inside the housing C of the circuit breaker D. As shown in FIG. This terminal B comprises a channel 1 comprising a top wall 2 , a bottom wall 3 and two side walls 4 , 5 , said walls forming a frame defining an opening 6 through which a connecting strip 7 of a device D passes.

[0029] The top wall 2 of the channel 1 comprises a threaded hole 8 into which a screw 9, called a terminal screw, is designed to be screwed.

[0030] exist Figures 1 to 4 Among them, terminal B is a movable channel type. In the unclamped position and the clamped position of the screw 9 , the end of the screw 9 is in electrical contact with the aforementioned connecting strip 7 . The terminal B also comprises a compensating spring plate 11 of steel, arranged between the end of the screw 9 (or the bottom of the screw) and the connecting strip 7, and designed to compensate possible bending of the terminal B. When no force is...

Abstract

The terminal has an indicator lever (12) moved between two positions indicating respective screwed and unscrewed states of a binding screw (9). The lever has one end cooperating with an opening (14) in a case (C) of a circuit breaker, and another end fixed to a cushion spring (11). The spring is deformed by the screw movement, between two shapes to relatively displace the lever between the two positions. The screw clamps a cable between a terminal casing and a connection area of the circuit breaker. An independent claim is also included for a safety device having a connection terminal.

Description

technical field [0001] The invention relates to an electrical connection terminal and an electrical protection device comprising such a terminal. Background technique [0002] An electrical terminal of the prior art comprises: a channel forming a frame surrounding an opening which receives a connecting strip of an electrical device and enables the insertion of a cable to be connected; a clamping screw designed to be inserted in the clamping of the cable between the connecting strip and the channel or said screw; and an indicator rod indicating the clamping quality of the screw, said rod being designed to cooperate with an opening arranged in the housing and to be available at A position in which it indicates the clamped state of the screw and a second position in which it indicates the unclamped state of the screw. [0003] Sometimes the cable lugs will become loose after long hours of work. This loosening causes a large temperature rise in the electrical device. It is th...
