Definitions

  • the invention relates to a device for fixing a magnetic release in one Residual current circuit breaker according to the preamble of claim 1.
  • Such a magnetic trigger is generally designed so that it is a U-shaped Yoke, a permanent magnet on the yoke, the free ends of the yoke legs covering anchor in the form of a hinged anchor and one of the yoke legs enclosing coil, which are housed together in a housing, a plunger protruding from this housing, which is driven by the armature becomes. If a fault current occurs, then that from the permanent magnet Magnetic flux in the yoke and armature is reduced, so that under the force of an opening spring acting hinged anchor opens, pushes the plunger out of the housing and thus unlatching a key switch.
  • a device for fixing has become known in which a wall section of a Carrier is provided which has an opening through which an ear is inserted can be.
  • the other ear is against with the interposition of a compression spring screwed a fixed wall, with in the path of movement of the plunger, in general so below the plunger, a lever is located, which has a latching point connected is.
  • the trigger can be adjusted by turning the screw becomes, whereby the distance between the ear and the fixed wall is reduced becomes; when the screw is loosened, the spring presses the ear against the Screw head, which makes adjustment possible.
  • the ear Since the ear is only to the screw head is fixed there, but not with respect to the spring, it can in the case of assembly, so if the release is installed in a residual current circuit breaker, that the distance of the ear from the stationary wall changes, which also causes the Distance of the plunger from the lever is changed. It also becomes the trigger moved perpendicular to the plunger so that the other ear can be inserted into the opening can; if the plunger protrudes from the housing, it can hit the lever strike and get damaged.
  • the one wall with the Opening and the fixed wall connected to a circuit board of the key switch.
  • the trigger is disconnected fixed by the switch mechanism in the housing of the residual current circuit breaker.
  • the object of the invention is to provide a device of the type mentioned at the outset, where there is a risk of relocation of the housing of the magnetic release Assembly is avoided; In addition, it should also be prevented that the from the Housing protruding plunger is damaged during assembly.
  • a carrier is provided, the two at a fixed distance has walls running parallel to one another, which have recesses into which the trigger can be snapped in with its ears in the direction of the plunger.
  • the carrier which is made of sheet metal exists, have a U-shape, the legs of which form the walls.
  • the recesses, in which the ears can be inserted are perpendicular to the free ones End edges of the legs.
  • the housing is inserted with its ears into the carrier in this way is that the direction of insertion is in the direction of the plunger, so that the plunger a movement to a latch lever and not across it, so that Damage to the tappet is avoided in this embodiment.
  • a particularly advantageous embodiment can be seen in the fact that the locking arms L-shaped, one of the legs in the direction of insertion of the magnetic release housing runs and ends at a distance from the bottom edge of the recess, so that after snapping the ears between the bottom edge and the ends one leg is locked.
  • an opening may be provided, whereby between the bottom edge and the Breakthrough a web is formed, which is deformable for fine adjustment of the trigger is.
  • This deformation can be caused by a tool against the bottom edge or against someone engaging in the opening of the ears from the bottom edge Projection is deformed so that the web receives a deflection, so that the Distance of the plunger from a lever of a latch is changed.
  • the carrier can be formed directly on the boards, so that protrude from the boards that hold the magnetic release.
  • Fig. 1 shows schematically the lower part 10 of a residual current circuit breaker in which for example contact points, arc extinguishers and the like. and possibly also the Total current transformer of the residual current circuit breaker is housed.
  • This lower part is supplemented to a whole residual current circuit breaker by the dashed lines shown contour 11, from the front of a switch toggle 12 and a test button 13 protrudes.
  • a fixation device 14 for an electromagnetic Trigger 15 arranged, which comprises a carrier 16 on which two in Distance parallel to each other and fixed in their distance from each other extending walls 17 and 18 are formed. Between these walls 17 and 18 is the trigger 15 used, the housing projecting in the opposite direction Ears 19, 20 has. How to fix the trigger 15 between the walls 17 and 18, FIG. 2 shows
  • the internal structure of the magnetic trigger 15 is known, so that it is not described in detail here must be received. It is essential that from the in the drawing Fig. 1 and 2nd a plunger 22 protrudes below the housing wall 21, which occurs during a switch-off operation presses against a lever 23 which is actuated so that one in one is not closer Latching point of the residual current circuit breaker shown is released.
  • FIG. 2 shows a longitudinal sectional view through the wall 18, which has a recess 30 has, which has approximately a U-shape.
  • the distance between the free end of the legs 37, 38 from the bottom edge 36 is such that that provided between the bottom edge 36 or one in the bottom edge Indentation 41 the ear 19 can be snapped into place.
  • the trigger 15 inserted with his ear 19 between the edges 39 and 40 and after passing the free ends of the legs 37 and 38 snap these over the edge of the ear 19, whereby the ear 19 is held.
  • the latch arm is designed to spring open with its leg.
  • a projection 44 is formed, which in a Opening 45 engages in ear 19 and thereby ear 19 in through the two ears 19 and 20 spanned plane holds.
  • the attachment of the opposite ear 20 to the wall 17 can be done in this way take place as shown in Fig. 2.
  • the wall 17 is the same Formed like the wall 18 according to FIG. 2.
  • the trigger 15 is then inserted into the Walls 17 and 18 easily possible: the insertion movement runs in the direction of the arrow P, whereby the ears 19 and 20 in the corresponding recesses of the walls 18 and 17 can be snapped into place.
  • This movement runs in the longitudinal direction of the Tappet 22, so that damage to the tappet by movement transverse to it is avoided become.
  • the wall 17 only has an opening into which the ear 20 is inserted; in this case the trigger 15 is first inserted with the ear 20 in the direction of the arrow P 1 and then pivoted clockwise about a point of rotation generated there, the ear 19 being locked in the wall 18.
