Definitions

  • the invention relates to an armature for a magnet system, in particular of a switching device, in one piece, with lateral pole faces.
  • a generic anchor is disclosed in DE 44 36 832 C1.
  • the anchor is with an anchor plate and starting from it Fastening device in one piece as a magnetically active Steel part executed. He has an implementation for admission of a bolt that is opened by one from the bottom of the Steel plate up to an elevation extending from this Recess is formed.
  • the anchor consists of one Steel block from which the outer contours for the steel plate with the fastening device and in a further step an elongated hole is milled to create the implementation.
  • the Anchor is for a magnet system, especially a contactor, intended.
  • the invention has for its object an anchor above-mentioned type with the lowest possible manufacturing and To create costs.
  • the object is achieved in that the anchor is manufactured as a sintered part and has an H-shaped design has, the plate-shaped side Pole surfaces by one that is both superior in their thickness extension Are connected to each other.
  • Such Execution has considerable advantages. It enables a simple and inexpensive design, at who created high-quality surfaces without post-processing and at the same time the through opening for the recording a bar can be produced.
  • Through the free design as a sintered part is a simple flow and mass optimization possible.
  • the figure is an anchor 1 for a magnet system, in particular a switching device, e.g. a contactor, in one-piece design. It has an H-shaped design, with lateral, plate-shaped executed pole faces 2, which are both in its thickness extension on both sides of the central web 3 are interconnected.
  • the anchor 1 is a sintered part manufactured. Its pole faces 2 are tapered towards the edge here, to achieve flow and mass optimization.
