Definitions

  • the invention relates to an electromagnetic release for a residual current circuit breaker according to the preamble of claim 1.
  • Electromagnetic releases are usually used in residual current circuit breakers, which comprise a plastic housing in which a U-shaped yoke, a Permanent magnet, a coil and an armature are used, which are ready to trip Condition against the force of a spring from the permanent magnet which is also in the housing is pulled against the yoke.
  • the trigger also has one Pin that is coupled to the armature and that protrudes from the housing. When a Fault current occurs, then the coil is opposed to the permanent magnetic flux Magnetic flux generated so that the spring pulls the armature from the yoke and the pin on a latching point in the switch lock of the residual current circuit breaker can act.
  • the permanent magnet Due to currents flowing in the residual current circuit breaker, the permanent magnet can be influenced so that the response value of the trigger is not or only insignificantly is changed.
  • the object of the invention is an electromagnetic release of the aforementioned Way to improve that its response value is not or only insignificantly is changed.
  • This object is achieved in that the housing of one magnetic iron sheet is at least partially surrounded.
  • the iron sheet essentially comprises the broad sides and the narrow sides of the Housing and at least partially the side from which the pin comes out of the housing protrudes.
  • the iron sheet or shielding sheet is punched out of a sheet metal plate and suitable Way folded.
  • the housing of an electromagnetic release 10 in which a not shown U-shaped yoke, a permanent manget, a coil and an anchor and one Are housed, has an approximately cuboid housing with broad sides 11, a fastening surface 12, a front side 13, which is parallel to the fastening surface 12 runs, and narrow sides 14 and 15, with between the narrow sides 14 and 15 respectively and the front 13 are each provided transition surfaces 16 and 17, the under run at an angle to the narrow side 14 or 15 or front side 13. From the front 13 protrudes through an opening 18, a pin 19, which with the not shown Anchor is coupled.
  • the broad sides 11, the narrow sides 14 and 15 and the inclined surfaces 16 and 17 are covered by a shield 20, the development of which is shown in FIG. 2.
  • the shield 21 has a first section 21 on both sides of a line of symmetry SS, the height H 1 of which corresponds approximately to the height of the trigger housing between the fastening surface 12 and the front side 13.
  • This is followed by a section 22, the height of which is adapted to the height of the side surface or 15; a section 23 is also provided, the height of which is H 1 .
  • the transition from section 22 to section 21 is an oblique edge 24 which cuts into section 21 from section 22.
  • the angle of the inclined edge 24 is adapted to the inclined surface 16.
  • the section 22 also goes into the section 23 via an oblique line 25 and a flap 26 is formed on this oblique line 25, the length L of which corresponds to the width of the section 22.
  • the width of the tab B corresponds to the dimension of the inclined surface 16 or 17 between the narrow side 14 and the front side 13.
  • the shielding which can be placed over the housing 11, is produced as follows:
  • the unwound shield is punched on a sheet metal part.
  • section 21 is angled by 90 °.
  • the sheet is along the Dashed line 28 also angled by 90 °, so that the section 21 runs parallel to section 23 and section 22 perpendicular to it.
  • the tab 26 folded down about the inclined line 25 so that the free end of the tab 26 rests on the inclined edge 24.
  • Sections 21 and 23 then cover the broad sides at least half off and section 22 covers the narrow side 14.
  • the tab 26 covers the inclined surface 16 in the area of the front. If the same then also with the part of the unwound located to the right of the symmetry line S-S Shielding is carried out, the perspective view shown in FIG. 1 is obtained Shielding, which has approximately a cup shape, which is adapted to the housing 11.
  • sections 21 and 21a Provide beads or recesses 30 with which the shield 20 on the housing 11 can be locked.
  • the shield 20 is placed on the housing 11 from the front 13 out.
  • the section 21a has a recess 33 in the area of the permanent magnet, um magnetize this to the trigger point by means of a suitable flooding.
