Definitions

  • the first spring (7) that is to say the one which biases the tilting contact carrier (5), is arranged so as to act on the trigger lever (16), via the link (13), so that this trigger lever pushes the free end of the pawl (17), against a stop (22), and the trigger means intervene so as 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 an apparatus 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 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, to cause the contact carrier 3 to return from its closed position to its open position.
  • the mechanism 1 is arranged so as to allow the lever 2 to reset the switch, that is to say to re-tighten the mechanism 1 by returning it from its open position after tripping (FIGS. 4 and 8) to its normal opening position (FIGS. 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 switch is housed in an insulating housing 9 from which the button 2a of the handle 2 emerges.
  • the assembly is such that, when the mechanism 1 is relaxed by the action of the relay 7, the tension of the spring 64 is found. greatly increased, by spacing the two ends of this spring.
  • a stop (not shown) limits the angular travel of the part 63 under the effect of the thrust exerted by the push rod 25 of the relay 7.
  • the pawl 50 is generally provided with a notch 28, suitable for receiving a spout 30 carried by the trigger lever 17.
  • This spring 6 keeps the or each movable contact 4 separate from the corresponding fixed contact 5.
  • the trigger lever 17 is held both by its fixed axis 18 and by the stop of the axis 14 against the end 23 of its groove 19, so that the spout 30 has inside the notch 28 a play visible in Figure 18.
  • the handle 2 which tends to be moved counterclockwise by the spring 8, is held in a stable position by all of the contact carrier 3 (in support on the stop 41), of the link 13 and of the link 10 (both bearing on the groove 19).
  • the tilting operation instead of being constituted by a handle 2 with a button 2a, could be constituted by a double lever mounted on the housing 9 so as to be able to rotate around a fixed axis and urged by a spring tending to rotate this double lever anti-clockwise.
  • This double lever is pushed in the closing direction and in the opening direction respectively by two push buttons.
  • FIG. 20 differs from that of FIGS. 14 to 19 essentially by the fact that the push rod 25 acts on the free end of the pawl 50 with interposition of the free end of a blade of one piece 73 which pivots at its other end on the housing 9 or an element integral with the housing and which replaces the fourth spring 64 of the previous embodiment.
  • the part 73 has an elastic blade 74 which is oriented towards the path of the axis 15 of the contact carrier.
  • the rotation of the part 73 is accompanied by the downward tilting of the blade 74.
  • the axis 15 which rises upwards meets the leaf spring 74 and making this blade switch back in the opposite direction, causes the relay to reset.
