  • materials may be conceivable which last or do not contract after the overmolding process, but contract with the aid of a further process step (such as reheating) to increase the bond between the metal part and the overmolded plastic to achieve the desired longitudinal water tightness.
  • the at least one embossing in its course around the metal part has the same cross section and / or in its course around the metal part a changing cross section.
  • the metal part is a stamped grid or cable of a connector and the encapsulation at least partially forms a housing of the connector.
  • a component known per se namely a plug connector, in particular a plug connector for use in vehicle technology, can be further improved in this field with respect to the longitudinal water tightness.

  • the shape of the embossment can be freely selected, thereby ensuring that in the overmolded area and adjacent adjacent areas the surface, with which the encapsulation rests against the metal part, is markedly increased by the imprints in order to ensure the longitudinal water tightness and, if necessary, at the same time also to effect a strain relief.
