Definitions

  • the invention relates to an electromagnetic release for an electrical switching device, in particular for a circuit breaker or motor circuit breaker according to the preamble of claim 1.
  • Electromagnetic triggers are generally designed as hinged armature or plunger armature triggers which have a magnet coil, a magnet core which is surrounded by the magnet coil, a magnet armature and a magnet yoke.
  • the magnetic core is firmly connected to the magnetic yoke; if the magnet armature is designed as a plunger armature, a coil body is provided which surrounds the magnet armature and the magnet core and effects the guidance of the magnet armature.
  • the solenoid is wound around the coil body, which is normally a single or multi-layer, cylindrical solenoid made of enamelled copper wire.
  • the coil body between the magnet coil and the magnet core or the magnet armature is either made of insulating material or a non-ferrous metal, for example made of aluminum.
  • the known magnetic triggers are relatively large.
  • the object of the invention is to improve a magnetic release of the type mentioned, in particular to provide it with smaller dimensions.
  • the magnet coil is accordingly formed by a wound copper foil, the inner turn of which - without the interposition of a coil former - is mechanically fixed and electrically conductively connected to the magnet core and guides the magnet armature. Since the magnetic core is attached to the magnetic yoke and the fixed contact piece of the electrical switching device is attached to the magnetic yoke, the inner turn is also conductively connected to the fixed contact piece. The turns following the inner turn are isolated from each other. On the outer turn, i.e. H. At the free end of the winding there is a conductor which, according to the invention, is connected or firmly connected to the end of the winding over the entire width and which leads to a terminal of the circuit breaker.
  • the copper foil can also be provided on one side with a thin insulating layer, the position of the foil being so is chosen so that the bare side points towards the magnetic core and armature.
  • a particularly space-saving design of the magnetic release can be achieved if the coil core and the armature and thus also the winding have a rectangular cross section.
  • the magnetic release 10 has a closed magnetic yoke 11 (see FIG. 5), to the rear or right yoke web 12 of which is shown in FIGS. 1 and 5, a fixed contact piece 13 is fastened; Within the closed area of the magnetic yoke 11, on the web 12, a magnetic core 14 is fastened, which is only visible in broken lines in FIG. A winding 15, which surrounds the magnetic core 14 and is mechanically and electrically connected to it, is attached to the magnetic core 14.
  • the inner turn 16 surrounds a tubular space 17 in which a magnet armature 18 is guided, a compression spring 19 being arranged between the magnet armature 18 and the magnet core 14.
  • the coil 15 is made of copper foil, the side of the wound foil facing the magnet armature 18 or the magnetic core 14 being bare and the remote side being coated with insulating material.
  • a connecting conductor 21 is fastened to the outer turn 20 and is connected to the end of the outer winding 20 over the entire width of the coil 15.
  • FIG. 5 shows another view of the arrangement according to FIG. 1; the arrangement according to FIG. 3 is essentially the same; only the armature 30 and the core 31 shown in broken lines in FIG. 3 are different from the embodiment according to FIG. 1; the magnetic core 31 and the magnet armature 30 are rectangular, in the embodiment according to FIG. 3 the longer side edge of the cross-sectional shape runs parallel to the web 32, which corresponds to the web 12 and on which both the magnet armature 31 and the movable contact piece 13 (in FIG. 3 not shown) is connected.
  • FIG. 4 shows a section through the magnetic core 31.
  • a bare copper foil instead of a copper foil coated with insulation on one side; Insulating foils are introduced between the turns which adjoin the innermost turn 16, which is not shown. If one side of the copper foil is provided with an insulating layer, the position of the foil is chosen so that the bare side points in the direction of the magnetic core and armature.
  • the use of a rectangular magnetic core and magnetic armature results in a particularly space-saving design of the magnetic release.
  • the width B of the film corresponds approximately to the width of the magnetic release, the width B only being increased by the magnet yoke 11.
  • the lead 21 is a solid conductor; it can also be a flexible conductor and it is connected to a connecting terminal. As a result, a current flows from the connection terminal to the conductor 21, with a thermal release possibly being switched on up to the outer turn 20, the inner turn 16 and from there via the magnetic core 14/31 to the fixed contact piece 13.
