Definitions

  • the invention relates to a switch lock with toggle lever, in particular for residual current circuit breaker, the toggle lever is connected at one end to a manual actuator and the other end to a rotatably mounted pawl.
  • the switch lock of electrical switching devices normally works with a toggle lever, that is to say with two legs which are in principle rod-shaped and are connected to one another in an articulated manner.
  • the knee point of this lever system is rotatably coupled via its one leg to a pawl which rests on a stop. If the stop is removed, the pawl is released and the switching lock is released.
  • the invention has for its object to develop an easy-to-manufacture switch lock with symmetrical switching properties and yet high operational reliability.
  • the latch and toggle lever are made of molded material and are connected to one another by molded pins and corresponding bearing recesses.
  • the essential components of this switch lock can be made from relevant commercially available plastics, in particular from such sufficient strength and with good sliding properties.
  • Such a switch lock has the advantage that few components are required, which can be manufactured with sufficient precision and whose bearings do without grease.
  • the toggle lever is fork-shaped on the pawl side and provided with bearing recesses for pins which are integrally formed on the pawl.
  • the fork-shaped part of the toggle lever is sufficiently elastic to be snapped onto the pegs of the jack with its bearing recesses.
  • the bearing recesses can be cut in their walls. You can also form the pawl from hard molded material and the fork of the toggle lever from elastic molded material if the hard plastic desired for the pawl is not sufficiently elastic in the fork-shaped part of the toggle lever.
  • a pawl of the switch lock according to Fig. 1 is shown in supervision of the pawl nose and bearing journal.
  • FIG. 3 shows the fork-shaped part of a toggle lever in the view corresponding to FIG. 2.
  • the toggle lever 1 has a toggle lever 1 made of parts 3 and 4 connected to one another by knee joint 2.
  • the toggle lever 1 is connected at one end to a manual control element 5 and at its other end to a pawl 8 which is rotatably mounted on the circuit board 6 by the joint 7.
  • the pawl nose 9 rests on a half-wave 10 in the usual way. It is essential that the pawl 8 and the toggle lever 1 are made of molded material and are connected to one another by molded pins 11 and corresponding bearing recesses 12.
  • the toggle lever 1 is fork-shaped on the latch side. This fork 4 can be seen more clearly from FIG. 3.
  • the bearing recesses 12 are cut in their walls in order to be able to insert the bearing pins 11 of the pawl 8 according to FIG. 2 more easily into the gate recesses 13.
  • the bearing pins 11 can be flattened on the insertion side, as can be seen from FIG. 2.
  • the pawl can be made of hard molding material, such as duroplastic, and the fork 4 of the toggle lever 1 can be made of elastic molding material, such as thermoplastic. Another, more elastic, thermosetting plastic can be used for the toggle lever.
