Definitions

  • the manufacturing can take place as follows:
  • the winding 4 is produced by winding in hot air and on a temporary mandrel of a conductive wire coated with a thermoadherent insulator.
  • the temporary mandrel is removed at the end of the winding and the ends of the winding 4 tinned, one of them being furthermore bent.
  • the plunger core is made from a ferromagnetic rod with a diameter less than that of the winding at the end of which is screwed a plastic headless screw.
  • the windings 4 are oriented parallel to the width of the metal strip.
  • One of their ends 35 is not bent, it escapes tangentially and arrives perpendicularly to the finger 21 of one of the connection pads 2 while their other end 36 is bent parallel to their axis after having escaped tangentially and arrives in the axis of the finger 21 of the other connection pad 3.
  • This arrangement allows the winding of one of the pads to be brought closer so that it is facing the hollow part of the cover and leaves relative to the other shoe sufficient space to accommodate the solid part 8 of the cover supporting the thread in which the plunger core is screwed.
