Definitions

  • the pivoting cradle directly drives the trigger hook during the rearming phase, which requires a large sliding stroke generating friction forces between the two mechanical members.
  • the cradle and the trigger hook must be milking suitable surface elements which increase the manufacturing cost of the assembly.
  • the object of the invention is to remedy these drawbacks and to allow the production of an operating mechanism with reduced friction which does not require additional surface treatments.
  • the mechanism according to the invention is characterized in that the upper link of the toggle joint is articulated to the trigger hook and is extended by a transmission lever cooperating with the cradle to cause the reset of the trigger hook in the armed position for attachment to the latch when moving the lever from position D to position R for resetting close to position 0. Resetting the mechanism by means of the upper link of the toggle joint generates a slight sliding stroke of the transmission lever on the cradle, and the corresponding friction is negligible.
  • the free end of the transmission lever of the upper link is shaped as a control tab bearing on a sliding surface of the cradle between positions D and 0 of the lever.

  • the captive mounting of the pin 88 does not require any means of immobilization in translation, such as circlips.
  • the central boss 90 comes directly from molding.
  • the half-moon 86 is provided with an unlocking tab 96 cooperating with the striker of the trigger block to cause the triggering of the mechanism 28 in the event of a fault.
  • the triggering results from a pivoting of the half-moon 86 in the trigonometric direction indicated by the arrow F 1 (fig. 2) followed by the introduction of the locking nose 98 into the window 100 of the lock 78.
  • the latter does not is no longer locked by the half-moon 86, and the torque exerted by the trigger hook 64 in the armed position causes the latch 78 to tilt clockwise (arrow F 2 ) towards the unlocked position.
  • the attachment spout 76 is then released from the latch 78, and the trigger hook 64 automatically pivots about the axis 74 towards the disarmed position under the action of the springs 66 of the mechanism 28.
  • an elastic means positions the half-moon 86 relative to the latch 78 so as to provide a predetermined clearance d (fig. 1) between a projection 102 of the half-moon 86 and the plate 48.
  • the presence of the clearance d prevents any transmission of shocks from the plate 48 to the half-moon 86.
  • the elastic means for positioning the half-moon 86 is produced by a torsion spring 104 including one strand 106 is supported on two bosses 108 of the half-moon 86 (fig. 9).
  • the spring 104 is threaded on the rod 82 of the stop of the latch 78, and the other strand 109 of the spring 104 is in contact with a curved tab of the fixed plate 48. Note the dual function of the torsion spring 104 which serves as a means of returning the half-moon 86 to the locking position of the lock 78 and as a means of elastic positioning of the half-moon 86 relative to the plate 48 and to the lock 78.
  • Each upper link 58 in V of the toggle joint 52 comprises a first lever 110 delimited by the axis 54 of pivoting of the toggle joint and the axis 62 of articulation of the trigger hook 64.
  • a second lever 112 extends from the axis 62 towards the cradle 68 at an acute angle with the first lever 110-
  • the free end of the second lever 112 is shaped as a transmission lug 114 folded at right angles and cooperating with the pivoting cradle 68, so as to drive the trigger hook 64 towards the armed position for hooking the spout 76 to the latch 78.

  • the positioning of each wedge 126 on the bar 30 s' operates after manual separation of the contact arm 32 corresponding against the force of the compression spring 46. Adjustment shims 126 having different thicknesses can be used to best compensate for manufacturing tolerances.
  • the mechanism 28 is rearmed by manual movement of the handle 26 clockwise from position D to a reset position R close to position 0.
  • the transmission lever 112 of each upper link 58 of the toggle joint 52 is driven upwards by reaction of the surface 116 of the cradle 68 on the tab 114 at right angles.
  • the latter moves on the surface 116 in a sliding movement of low amplitude whose corresponding reaction forces do not generate significant friction. This results in a tilting around the axis 74 of the trigger hook 64 urged clockwise towards the armed position (fig. 5), in which the hooking spout 76 hangs on the latch 78 in support of the stop 82.
  • the half-moon 86 maintains the latch 78 in this position, and the tab 114 of each link 58 remains in stable support on the surface 116 of the cradle 68.
  • the auxiliary reset rod 72 secured to the cradle 68 causes the energy storage device associated with the trip unit to be reset.
  • the closing of the circuit breaker occurs in a conventional manner by a reverse rotation of the handle 26 towards the opposite position F (fig. 7), urging the axes 62, 54, 60 of the toggle joint 52 substantially aligned position.
  • the clockwise pivoting movement of the tab 114 of the upper links 58 does not interfere with the trajectory in the opposite direction of the projection 118 of the cradle 68 actuated towards the position F of the lever 26.
