Definitions

  • the invention relates to electrical devices with automatic cut-off, in particular to differential switches, circuit breakers or differential circuit breakers, of the type comprising those between a rotary operating member and a tilting contact carrier on which is mounted at least one cooperating movable contact.
  • a toggle and ratchet mechanism capable, on the one hand, when this mechanism is tensioned, to transmit the movement of the operating member to the contact carrier both in the opening direction and in the opposite direction or closing direction and, on the other hand, when this mechanism is relaxed by means trigger acting independently of the actuator on the pawl, causing the return of the contact carrier from its closed position to its open position, this mechanism being arranged to man iere to allow the operating member to rearm the device, that is to say to tighten the mechanism by bringing it back from its open position after tripping to its normal open position, after cessation of the intervention of the triggering means and under the action of a second
  • the first spring (7) that is to say the one which biases the tilting contact carrier (5), is arranged to so as to act on the trigger lever (16), by means of the link (13), so that this trigger lever pushes the free end of the pawl (17), against a stop (22), and the means of trip occur in order to erase this stop.
  • the pawl In the closed position ( Figure 1), the pawl is not of itself in a stable position and it is indirectly that the triggering means put the pawl out of action, which causes delays in the opening of the contacts (2, 3) after intervention of the tripping means.
  • CH-A-387 760 describes a device similar to that of DE-A-1 490 307 but in which the stop erasable by the triggering means does not cooperate with a pawl but directly with the trigger lever.
  • the invention aims to make electrical devices of the kind defined above such that their operation is more secure.
  • the device of the kind defined above is essentially characterized in that the pawl is arranged in such a way and in particular its axis is located in such a way that this pawl occupies itself a stable position, it that is to say a position in which the action of the first spring is unable to rotate the pawl about its axis, in the closed position of the device, and in that the triggering means are arranged so as to act mechanically by pushing on this pawl, against the action of the third spring.
  • the triggering of the device is made faster and safer.
  • the fixed axis of the trigger lever is located in such a way that, in the closed position, this trigger lever is approximately parallel to the assembly of the connecting rod and the connecting rod, which has the advantage of minimizing not only the reaction exerted on the pawl in this closed position, but also the volume necessary for housing the mechanism.
  • the connecting rod consists of a rod, generally rectilinear, the two ends of which are folded at right angles so as to constitute respectively the axis of articulation of the connecting rod with the operating member and its axis of articulation with the rod.
  • This link is advantageously double so that the part of the contact carrier by which the articulation is made with the double link is placed between the two individual links, the latter being preferably secured to avoid problems of overhang .
  • the useful length of the connecting rod that is to say the length between its articulation axes, is clearly greater than that of the connecting rod, which contributes to making the movement of detent or "Break" of the knee brace.
  • the length of the groove of the trigger lever is such that the axis of articulation between connecting rod and connecting rod abuts against one of the longitudinal ends of this groove during the resetting movement, which allows the operating member bringing the trigger lever positively into engagement with the pawl, towards the end of this rearming movement.
  • the third spring, or return spring of the pawl is advantageously attached, by one end, to a lever arm secured to the pawl and, by the other end, to the link, preferably at the axis of articulation of the latter with the contact carrier, the assembly being such that the relative movement of the pawl and of the rod following the contact carrier, during the tripping movement, has the effect of increase the tension of this third spring and consequently ensure the subsequent reset movement of the relay.
  • the rotary actuating member can be actuated manually either directly by a button integral with this member which will then be designated hereinafter by “lever”, or indirectly by two push-buttons acting alternately on this member in the opening direction and in the direction of closing.
  • the triggering means which generally consist of a relay, act directly on the pawl and this is the third spring defined above, that is to say the spring of the pawl, which alone ensures the recall of the triggering means.
  • this third spring is hooked, at one end, to a lever arm secured to the pawl and, at the other end, to the link, generally at the level of the axis of articulation thereof with the contact holder.
  • the triggering means act on the pawl by means of an additional movable part which is subjected directly to the action of a fourth spring and, through the pawl, to that of the third spring.
  • this movable part is mounted on a pivot axis fixed relative to the housing and parallel to the above axes.
  • the fourth spring is attached, at one end, to a lever arm secured to the moving part and, at the other end, to the link.

  • the assembly of the contact carrier 3 and of the movable contact (s) 4 is preferably arranged in the manner described in patent application EP-A-0 142 402, that is to say so that the (s) same (s) spring (s) 6 ensures (s) both the separation of the contacts 4 and 5 during the opening movement and the pressure of these contacts 4, 5 one on the other in the closed position.
  • the mechanism 1 is capable, on the one hand, when it is stretched, of transmitting the movement of the lever 2 to the contact carrier 3 both in the opening direction and in the closing direction and, on the other hand, when the mechanism 1- is relaxed by triggering means such as a relay 7 acting independently of the lever 2 on the pawl 20 of the mechanism 1, causing the contact carrier 3 to return from its position closing in its open position.
  • the mechanism 1 is arranged so as to allow the lever 2 to reset the switch, that is to say to tighten the mechanism 1 by returning it from its open position after tripping ( Figures 4 and 8) to its normal open position ( Figures 2 and 5), after cessation of the intervention of the triggering means 7 and under the action of a second spring 8 acting on this lever 2.

  • the pawl 20 is arranged in such a way and in particular its axis 21 is located so that this pawl 20 occupies itself a stable position, in the closed position of the device . In other words, the action of the springs 6 on the trigger lever 17 is unable to rotate the pawl 20 around its axis 21.
  • the fixed axis 18 of the trigger lever 17 is located so that, in the closed position (see in particular Figures 3 and 7), this trigger lever 17 is approximately parallel to the assembly of the connecting rod 10 and the connecting rod 13 , this axis 18 then being practically aligned with the axis 11 between lever 2 and rod 10.
