Definitions

  • An electromagnetic release for a switching device uses, among other things, a release coil, a release armature, a magnetic core and a magnetic yoke.
  • the trip armature is separated from the magnetic core by an air gap. If a sufficiently large current flows through the tripping coil, the tripping armature is set in motion to bridge the air gap in the direction of the magnetic core. The movement results from the magnetic field building up, the magnetic yoke serving to close the associated magnetic circuit as far as possible.
  • the magnetic core has an effective core surface adjoining the trigger coil at the end.
  • the advantage here is that no separate or integrated magnetic core has to be attached or shaped. Both the material required for this and any attachment can thus be saved.
  • the magnetic core is inexpensively formed with an end piece of the base body as a U-shaped or as a closed profile.
  • End piece of the base body is plate-shaped.
  • This embodiment variant is also characterized by low material consumption and therefore inexpensive production.
  • the base body forms a leg with its free end, which has a recess arranged therein, which also serves to guide the release anchor. This is a useful and parts-reduced storage. An extension for electrical connection to the is preferred
  • 15 and 16 show an eighth magnetic yoke in different views.
  • the second magnetic yoke 1b differs from the first magnetic yoke 1a according to FIG. 1 in that a second free end 11b is developed into a leg 12 and extends in the same direction as the end piece 10a according to FIG. A recess 13 is made in the leg 12, in which an extended trigger anchor 7b is guided and supported.
  • the basic body 2e comprises a modified magnetic core 3e with an end piece 10e and an adapted ear-shaped region 4e.
  • the end piece 10e is angled twice clockwise to the magnetic core 3e in such a way that a U-shaped profile is provided which is open on one side.
  • a release coil In the functional connection of the new magnetic yoke with an electromagnetic release for a switching device, a release coil, a release armature, a magnetic core and a magnetic yoke are used.
  • the trip armature is separated from the magnetic core by an air gap. If a sufficiently large current flows through the tripping coil, the tripping armature is set in motion to bridge the air gap in the direction of the magnetic core.

Abstract

L'objectif de la présente invention est de produire une culasse d'aimant (1a-1h) conçue pour un interrupteur électromagnétique (14a-14c) et qui, tant du point de vue du montage que de l'encombrement, soit économique et/ou optimalisée. A cet effet, le corps de base (2a-2h) de ladite culasse d'aimant (1a-1h) et le noyau de l'aimant ne forment qu'une seule pièce.
