- FIGS. 13 and 14 show a terminal B such as that of FIGS. 1 and 2, this terminal B being mounted inside the housing C of a circuit breaker D.
- the indicator 13 provides two functions, namely a first function indication of the tightening state of the terminal B and a second function of unlocking mechanism M of circuit breaker D.
- FIGS. 15 and 16 show a terminal B according to the invention, this terminal B having an elastic piece 26, said piece having an elastic blade 27 and a lever 12 integral with said blade 27.
- This blade 27 is constraint between the screw 9 and the casing 28 of the apparatus D at its two ends, so that said blade 27 polarizes the screw assembly 9 / terminal B towards the high in the unclamped position of the screw 9, and that the tightening of the screw 9 generates a deformation of the blade 27 causing a corresponding displacement of the indicator 12 to a position indicating a tight state of the screw 9.
- the terminal B is not in operation, the spring plate 11 being in a non-active state in which it has a curved shape.

- the spring plate 11 is supported by two opposite edges 30, 31 on the connection pad 7 and flexes to become flat.
- the deformation of this plate 11 has resulted in the moving the lever 12 to a position in which the portion 13b of the indicator 13 is no longer facing the orifice 14 of the housing C but under the upper wall of the housing C.
- the portion 13a of the indicator 13 is then facing the orifice 14 of the housing C, indicating in this way, a tight position of the screw 9 of terminal B.
- the plate spring 11 In case loosening of the terminal B or creep due to vibrations, the plate spring 11 is urged towards its initial position, that is to say curved, so as to compensate the loosening of terminal B and the indicator lever 12 moves to a position in which the portion 13b is located opposite the orifice 14 of the housing C so as to report to the operator the defective quality of the tightening of terminal B.
- terminal B illustrated in Figures 3 and 4 will not be described again because it is the same as that described in Figures 1 and 2, except that the indicator lever 12 is, in FIGS. 3 and 4, movable between a position in which it projects from the housing C (FIG. 3) so as to signal the loosened state of the terminal B and a position in which the lever 12 is housed inside the case 16 of the housing C (fig.3) indicating in this position, the tight state of the terminal B.
- the horizontal external branch 33 is parallel to the horizontal inner branch 17 with a vertical offset uniform J1 corresponding to a first game.
- the part 13b of 13 of the lever 12 is not located opposite the orifice 14 of the housing, but it is the part 13a which indicates the loosened state of the screw.
- the first tightening threshold is reached in beginning of tightening of the screw 9 when the end of the internal branch 17 has caught up with the first set J1 and comes into abutment against the underside of the outer branch 33.
- the cage 1 becomes more rigid, and the axial force traction F in terminal B increases rapidly with the second slope of curve B (Fig.a). This results in a slight uplift of the outer branch 33 in the direction of the arrow F, which branch 33 is capable of coming into engagement with the barrel of the screw 9 when a predetermined threshold is reached.
- the indicator lever 12 is moved until the portion 13b of the indicator 13 is located facing the orifice 14 of the housing C so as to indicate the tight state of the screw 9 of terminal B.
- the screwing of the screw 9 is then made impossible, and we obtain a limiter of torque to generate a constant tightening force.
- the terminal B is of the fixed cage type.
- the screw 9 of terminal B is loosened and the portion 13b of the indicator 13 is opposite the orifice 14 housing C of the device.
- the screw 9 is in a tight state, the displacement of the screw 9 having caused the deformation of the upper portion 23 of the range 7 and the tightening of the conductor 29 between a support piece 32 and said range 7.
- the deformation of the elastic band 7 has led to the displacement of the lever 12 of way that the portion 13a of the indicator 13 indicates the tight state of the screw 9.
- the terminal screw 9 is in a loose state and the lever 12 then acts on the mechanism M of the circuit breaker D so as to cause the unlocking of said In this position, the indicator light 13 indicates the loosened state of the screw 9 of terminal by its portion 13b facing the orifice 14.
- the indicator 12 causes therefore triggering the mechanism M.
- This trigger mechanism M is driven in case of non-tightening of terminal B, due to an oversight or other, in case of loosening, or creep of the terminal due to vibration or other.
- the screw 9 is in a loose state, the elastic blade 26 being supported on the head of the screw 9, polarizes the screw assembly 9 and the terminal B towards the top of the device and the indicator lever 12 is located opposite the orifice 14 of the housing C.
- the screw 9 is in a tight position, the flattening of the blade 26 having led to the moving the lever 12 to a retracted position under the upper wall of the housing C of the apparatus D.
- the elastic part used may be a compensation plate bending or twisting or kinking.
- the invention can be applied also to the terminals intended to ensure the tightening of lugs or bars.
