Definitions

  • the invention is in the field of electrical switches which are equipped with a spring force drive for actuating contacts, and is to be used in the structural design of a switch lock for latching a spring accumulator.
  • a known switch lock for a spring force drive in which the associated spring accumulator is tensioned by means of a rotary drive and an extendable toggle lever system, the extendable toggle lever system is arrested when the spring accumulator is tensioned by means of a support element, an auxiliary pawl and a main pawl as well as a stop assigned to the main pawl.
  • the support element designed as a lever in which the support element designed as a lever is articulated on the one hand on the knee joint of the toggle lever system and on the other hand on the auxiliary pawl, the auxiliary pawl can be pivoted by stretching the lever system.
  • auxiliary pawl and the main pawl have mutually assigned working surfaces, via which the position of the main pawl can be influenced when the auxiliary pawl is pivoted (DE 44 16 088 Cl).
  • a first working surface of the auxiliary pawl is formed by a semicircular section of the peripheral edge of the auxiliary pawl, which rests on a working surface of the main pawl designed as a roller and holds the main pawl in a first position against the force of a return spring assigned to it. In this first position, a half-wave forming the stop is locked under spring tension by the main pawl.
  • the tolerance range of the force under which the main pawl rests against the stop and the tolerance range of the force required to release the latch must be matched to the tolerance range of the return spring. If the return spring assigned to the main pawl breaks, it is not possible to latch the tensioned spring accumulator.
  • auxiliary pawl and the main pawl each have at least two
  • Such a configuration ensures that the main pawl is pivoted at the end of the tensioning process in such a way that when the lever system is decoupled from the rotary drive it safely comes into contact with the stop under the force of the spring accumulator. Since no high restoring forces have to be taken into account in the design of the lock mechanism, especially when the spring energy store is high, both a small tolerance range of the force under which the main pawl rests on the stop and a small tolerance range of the triggering force can be provided.
  • Auxiliary pawl are formed and that on the other hand the first working surface of the main pawl from a nose of the main pawl and the second working surface is formed by a roller held on the main pawl.
  • a small stroke that is transmitted from the rotary drive to the lever system can be converted into a wide and thus sudden pivoting movement of the auxiliary pawl, regardless of the pivoting movement of the support element coupled to the lever system, if in a further embodiment of the invention for controlling the pivoting movement of the Auxiliary pawl a driver coupled to the lever system and a two-armed pivotable control lever are provided, the first lever arm of the control lever protruding into an end section of the movement path of the driver and the second lever arm being assigned to a driving surface of the auxiliary pawl.
  • a second driver coupled to the lever system can be provided in addition to the first driver and the control lever, which driver lies against a second driving surface of the auxiliary pawl when the lever system is stretched over a section of its movement path.
  • the first driver Mer is formed by the hinge pin of the lever system, wherein the hinge pin is assigned a nose-like extension of the control lever as its first lever arm and wherein a pin is formed on the second lever arm of the control lever, which engages in an elongated hole formed near the pivot point of the auxiliary pawl, the inner edge of which forms the first driving area.
  • the second driver can be designed as a bolt, which forms the knee joint of a toggle lever connection coupled to the lever system, the second driving surface being formed by a further section of the peripheral edge of the auxiliary pawl.
  • FIG. 1 shows the key switch with the spring accumulator fully relaxed
  • FIGS. 2 to 6 the switch lock in five different phases of the tensioning process and FIG. 7 the switch lock with the spring mechanism fully tensioned and latched.
  • Figures 1 to 7 show a switch lock integrated in a drive device for a low-voltage circuit breaker.
  • the drive device which is used to actuate a switch contact arrangement (not shown in the figures), has a spring accumulator 1 designed as a helical compression spring to provide the actuation energy.
  • a lever system that can be extended by means of a rotary drive is provided in this drive device, and the switching lock is used to lock it.
  • the lever system is composed of a roller lever 3 carrying a scanning roller 2, one on the spring Memory 1 articulated clamping lever 4 and a roller lever
  • the roller lever 3 is rotatably arranged on a first bearing pin 6 and the tensioning lever 4 on a second bearing pin 7.
  • the roller lever 3 and the coupling member 5 are connected by means of a first hinge pin 8 and the tensioning lever 4 and the coupling member 5 are connected by means of a second hinge pin 9.
  • the tensioning lever 4 is designed as a two-armed lever, one arm being articulated on the coupling member 5 and the other arm on the spring mechanism 1.

Abstract

L'invention concerne un mécanisme de verrouillage destiné au verrouillage de l'accumulateur à ressorts (1) d'un appareil à commutation électrique, cet accumulateur à ressorts étant tendu à l'aide d'un mécanisme de rotation (10 et 11) et d'un système de levage extensible (2, 3 et 4). Lorsque l'accumulateur à ressorts est sous tension, le système de levage extensible est verrouillé à l'aide d'un élément support (12), d'un cliquet auxiliaire (14), d'un cliquet principal (16) et d'une butée (17) qui est associée au cliquet principal (16). Le cliquet auxiliaire (14) peut tourner par extension du système de levage et la position du cliquet principal (16) pendant la rotation du cliquet auxiliaire (14) peut être influencée par des surfaces de travail mutuellement associées. Pour concevoir le mécanisme d'encliquetage de telle manière que le cliquet principal (16) puisse pivoter sans l'utilisation d'un ressort de rapport agissant sur le cliquet principal, le cliquet auxiliaire (14) et le cliquet principal (16) ont respectivement au moins deux surfaces de travail (24, 25 ou 26, 27). Une première phase de rotation du cliquet auxiliaire, les premières surfaces respectives des deux ensembles de surfaces de travail (24 et 26) sont en contact et, dans une deuxième phase de rotation du cliquet auxiliaire, les deuxièmes surfaces respectives de travail (25 et 27) sont en contact en s'emboîtant à la manière d'un engrenage.
