  • the sleeve comprises at least a fourth region, as a trained as a tongue area, which is for non-positive connection with a cable, in particular with the insulation of the cable, deformable .
  • the coating of the winding wire during manufacture of a welded connection is removable at least in the region of the electrical contact point, in particular by the heating occurring during the production of the welded connection.
  • the coil comprises potting compound, in particular in the region of the channel and / or the winding.
  • potting compound in particular in the region of the channel and / or the winding.
  • the coil carrier comprises a holder for winding wire and / or cable.
