Definitions

  • the invention relates to an electromagnetic actuator comprising, in a housing comprising a base covered by a cover, an electromagnetic circuit comprising a fixed armature resting on the base, and a movable armature capable of opening and closing the electromagnetic circuit, said fixed armature being taken between the base and the cover.
  • This type of trigger including the mounting it provides has a number of disadvantages.
  • the application of the fixed armature against the base is likely to cause in the latter stresses and uncontrolled deformations that can cause a bad positioning of the fixed armature, which affects the proper operation of the trigger.
  • An object of the present invention is to solve in particular the aforementioned drawbacks by proposing an electromagnetic release which, while being of simple design, has a reliable, precise, durable operation.
  • the invention proposes an electromagnetic trigger as presented in the introduction, characterized in that the base comprises an elastically deformable zone, capable of sinking under the pressure of the fixed armature, the dimensions and the conformation of the base, the cover and the armature being able to allow the clamping of the armature between the cover and said deformable zone which solicits it towards the cover under the effect of its own elasticity.
  • the pin occupies a median position in said deformable zone, which allows a substantially uniform distribution of the stresses in the deformable zone.
  • the carcass of the coil being secured to the fixed armature, it is likely to transmit its own stresses and deformations, especially during the assembly of the trigger, when welding the son of the coil on its pins, or again during the installation of the trigger, during which the pins intervene.
  • the fixed armature is thus likely to be veiled or folded, which can affect the air gap between the armatures and, in any case, is detrimental to the proper functioning of the trigger.
  • a further object of the present invention is to solve in particular the disadvantages which have just been exposed, by proposing an electromagnetic release whose design allows at least to limit the impact of external constraints on the fixed armature.
  • the invention provides an electromagnetic trip device comprising, in a housing comprising a pedestal capped with a cover, an electromagnetic circuit comprising a fixed armature resting on the base, and a movable armature capable to open and close the electromagnetic circuit, said fixed armature being taken between the base and the cover, the trigger further comprising a coil comprising a carcass on which is wound a winding, said carcass being threaded on the fixed and integral armature housing, characterized in that the carcass is rigidly mounted relative to the housing and floating relative to the fixed armature.
