This ensures that there is no gap between the surface of the cable sheaths and the surfaces of the associated sealing region of the sealing element, so as to prevent longitudinal water from flowing there.

If no longitudinal water-tightness is to be achieved with the sealing element part 2, 3, its function is to be seen in the fact that, when the encapsulation 5 is carried out, the encapsulation material is prevented from entering the contact chambers of the contact carrier 1.
  • the function of the sealing element 2, 3 is thus to be seen in that it only prevents either that Material of the encapsulation 5 penetrates into the contact chambers of the contact carrier 1 and does not contribute to the longitudinal water-tightness or its function is the fact that both the sealing element 2, 3 and the encapsulation 5 realize the longitudinal water-tightness.
