  • the diameter of the diameter step 112 corresponds to the diameter of the adjacent funnel end.
  • the diameter step 112 is formed as a clearance fit, this allows easier insertion of the left end of the sleeve until it reaches the end of the sleeve. level 112 is applied.
  • the diameter of the diameter stage 112 in this case is greater than the diameter of the funnel.
  • the left sleeve end has a rounding or inner bevel.
  • the abutment surface of the housing member 102 is an accurate fit. This case has already been explained in more detail with reference to FIG. 1.
  • the sleeve 105 is pressed with the hopper 110 to the diameter stage 112. This ensures that the penetration of plastic material into the interior of the housing element is avoided.
  • a diameter step 113 is formed, towards the left end in FIG. 2.
  • the contact sleeve 104 which is crimped, plugged (push-in) or welded onto the conductor 108, is surrounded in its connection region by the left sleeve half. It continues into the cylindrical cavity of the housing element 102 bearing against the left-hand end of the sleeve and extends up to the level of the diameter step 113 in the outer surface of the housing element 102.
  • the plastic material 107 is applied. This covers the right in Fig. 2 part of the outer surface of the housing member 102 to the diameter stage 113 and penetrates into a part of the cylindrical recess 111, which is not sealed by the voltage applied to the diameter stage 112 left half sleeve.
  • the plastic material 107 also surrounds the sleeve 105 and extends almost to the right in Fig. 2 end of the cable portion 103. In this case, the plastic material 107 also covers the shrink tubing 106 and the cable sheath 109 a cable portion which extends to the right of the shrink tubing 106.
  • the circumferentially applied plastic material 107 closes in the range from the diameter step 113 of the housing member 2 to the right sleeve end outward cylindrically, tapers from the right end of the sleeve and closes right in Fig. 2 again cylindrical, but therefore with a thinner layer of the plastic material 107.
  • the diameter of the left cylindrical end of plastic material 107 in the region of the housing member 102 is greater than the diameter of the housing member 102 including the molded rings 114 with the at least one connecting web to ensure a good pull / pressure relief and protect against cable twist.
  • polyurethanes or thermoplastic elastomers are preferably used as the weatherproof and temperature-resistant plastic material 107. When selecting the material, it is important, as already stated, above all that the plastic material 107 connects tightly to the heat-shrinkable tube 106, the sleeve 105 and the housing element 102.
  • the plug engages around the coupler when the two connector elements are brought together to form a plug connection.
  • the housing element 2 of the plug has an inner diameter step 13 and the housing element 102 of the coupler has an outer diameter step 113, wherein the outer diameter of the diameter step 13 exactly matches the inner diameter of the diameter step 113. If the two connector elements are brought together, the contact sleeve 104 and the contact pin 4 touch and are therefore in an electrically conductive connection.

Abstract

L'invention concerne un élément connecteur à fiche, comprenant une gaine à disposer tout autour d'un câble présentant au moins un revêtement et à solidariser avec le revêtement extérieur du câble, un contact à fiche à connecter électriquement à au moins un conducteur de câble à l'intérieur de la gaine, et un élément boîtier, qui enserre le contact à fiche et qui repose la gaine. Au moins une partie de l'élément boîtier reposant sur la gaine, la gaine elle-même, et au moins une partie du câble partant de l'élément boîtier ou de la gaine, sont enrobés d'un matériau de type matière plastique. L'élément connecteur à fiche comprend, de plus, une gaine thermorétractable qui assure une étanchéité entre le matériau de type matière plastique et le revêtement du câble.
