Definitions

  • the invention has for its object to design a switchgear housing of the type mentioned above such that rebounding of the armature is reduced in a simple and effective manner.
  • the second magnet support area is ribbed with closed frame profiles, since a hard resilient magnet support area is hereby implemented in a simple manner. If an embossed rubber is inserted between the magnetic yoke and the support strip, the spring properties of the soft magnetic support area can be influenced in particular depending on the height of the support strip.

Abstract

Afin de réduire le rebondissement de l'induit principal avec le porte-contact pendant la commutation d'un contacteur, le fond (9) de la chambre magnétique du boîtier (1) du contacteur est pourvu de deux zones de support de la culasse qui n'ont pas la même élasticité. A cet effet, le fond (9) susceptible de vibrer de la chambre magnétique comprend une bande de support dont les extrémités servent de zones de support (11, 12) de l'aimant.
