Definitions

  • the invention relates to a cable gland and in particular to a sealing element for such a cable gland.
  • Cable glands using a sealing element and a tightening nut for fixing and sealing a cable are widely known.
  • water or similar disturbing substances can accumulate in the screw connection.
  • accumulation may occur in a space of the cable gland formed between the outer circumference of the cable and the inner circumference of the tightening nut.
  • a sealing element which consists of a sealing ring, then of a connecting part and then a hat part.
  • the sealing element is preferably formed in one piece and consists of a plastic.
  • the sealing element is preferably used in a tightening nut of the cable gland and preferably extends along the entire length in the interior of the tightening nut and projects with its hat part over the upper end face of the tightening nut. Benachtbart to the lower end face, the sealing element forms the sealing ring, which has a larger outer diameter than the connecting part.
  • the sealing ring adjacent to the lower end face forms a bearing or pressing surface.
  • a preferably made of metal pressure washer 17 is used, which has the following advantage.
  • the invention further provides a cable gland for a connector. On a housing part of the connector, the tightening nut of the cable gland is screwed, wherein in the tightening nut, a seal of the type described above is used.
  • Figure 1 shows a section through a conventional PG cable gland
  • Figure 2 is a detail of Figure 1;
  • Figure 3 is an exploded view of the cable gland of Figure 2;
  • FIG. 4 shows the sealing ring of FIG. 3
  • Figure 5 shows an embodiment of the cable gland according to the invention in section
  • FIG. 6 shows a detail of FIG. 6
  • FIG. 7 is an exploded view of FIG. 6
  • Figure 8 shows the sealing element according to the invention in a perspective view.
  • FIGs 1 to 4 a PG cable gland 10 of the prior art is shown.
  • the cable gland 10 is used together with a connector 11 and a cable 13 to fix the cable 13 in the connector 11.
  • housing part 12 which forms an example annular support projection 14.
  • a pressure washer 18 on which in turn a sealing ring 16 is arranged.
  • a tightening nut 17 is screwed into the housing part 12 so that an external thread of the tightening nut is in engagement with the internal thread of the housing part 12.
  • a pressing pressure is exerted on the sealing ring 16, so that a seal between the outer space the connector and also an inner space 20, formed between an inner wall 27 of the bore of the feed nut 25 and the jacket of the cable 13, and the interior of the connector 11 is achieved.
  • the cable gland 100 like the cable gland 10 according to FIG. 1, consists of a tightening nut 25, and preferably two press disks 17 and 18, which cooperate with a sealing element 160 of the cable gland 100.
  • the sealing element 160 according to the invention - cf. Fig. 8 - is preferably in one piece and preferably made of a plastic.
  • the sealing element 160 consists of a sealing ring 31, a preferably conical connecting part 32 and a hat member 33.
  • the sealing ring 31 has approximately the shape and function of the sealing ring 16 according to Figure 1, but according to the invention via the connecting part 32 with the umbrella-like radially connected to the outside hat part 33.
  • the hat part 33 has a top 34 and a bottom 35, the latter rests on an upper end face 28 of the tightening nut 25, even in the assembled state of the cable gland 100.
  • the tightening nut 25 has a lower end face 29 which to an upper abutment or pressing surface 38 of the sealing ring 31 indicates.
  • One of the upper bearing or pressing surface opposite formed by the sealing ring lower abutment or pressing surface 39 is preferably via a press ring 18 with the support projection 14 in press connection when the tightening nut 25 is screwed firmly into the housing part 12.
  • a preferably made of metal pressing plate 17 is arranged.
  • the sleeve-shaped connecting part 32 is shaped such that it preferably fills the space 20 shown in FIG. After the space 20 between the inner wall 27 and the outer wall of the cable 13, for example, wedge-shaped, the wall of the connecting part 32 is also wedge-shaped in section.
  • the hat part 34 lies with its underside 35 sealingly on the upper end face of the tightening nut 25.
  • the sealing ring 31 with its outer diameter is greater than the outer diameter of the connecting part 32 at its widest point and smaller than the outer diameter of the cap part 33. Further, the underside 35 of the cap part 33 with respect to the longitudinal axis Z of the sealing element at an angle ⁇ less than 90 degrees, preferably between 85 degrees and 88 degrees.
