Definitions

  • the invention relates to a ribbon cable having a plurality of spaced apart in a plane spaced electrical conductors.
  • Such ribbon cables can serve to forward an electric current and thereby form circuits.
  • Ribbon cables are usually designed rectangular in cross-section.
  • the sealing of such a rectangular cross-section is problematic because such ribbon cables are usually mass products and, for example, by extrusion of a plastic material as insulation, in which the conductors are embedded, are produced.
  • the openings through which the ribbon cable are inserted into a connector or a housing part of components that are also made of plastic by way of injection molding.
  • the US 2005/0003709 A1 describes, for example, a waterproof sealing arrangement, wherein the ribbon cable and the seal are provided with an adhesive coating, by means of which the seal and the ribbon cable are tightly interconnected.
  • the elastic seal itself then takes over the seal, for example, to a connector housing.
  • the US 2002/0052141 A1 describes an arrangement in which a soft elastic seal is materially connected to a cable and the soft elastic seal is then received in a corresponding sealing portion of a housing. The seal is formed directly on the ribbon cable.
  • the object of the invention is to provide a ribbon cable that is suitable for mass production and beyond a secure seal against a passage in a housing directly or even with respect to a seal having a passage can achieve without it special mediating Treatments needed.
  • a ribbon cable with a plurality of spaced apart in a plane spaced electrical conductors, which are enclosed by an insulation of a thermoplastic material, which a first outer surface which extends at a distance from the plane in which the conductors are arranged next to each other at a distance, a second outer surface which extends at a distance from the first outer surface and the plane, wherein the distance between the two outer surfaces forms a thickness, at their lateral longitudinal ends the two outer surfaces connecting end portions which extend in the longitudinal direction of the ribbon cable and are rounded, wherein extend beyond the outer surfaces in the thickness direction and form rounded transitions to the outer surfaces.
  • the rounded end portions provide sufficient material to achieve an exact seal even in a rectangular passage or inaccurately made passage.
  • the passage does not necessarily have to be exactly adapted to the shape of the ribbon cable.
  • the cost of the tight mounting of such a ribbon cable reduce significantly, even if the ribbon cable with only a relatively stiff trained Component (eg seals made of a harder material, such as silicone) cooperates, which has the passage for the ribbon cable.
  • a relatively stiff trained Component eg seals made of a harder material, such as silicone
  • the ribbon cable is used in conjunction with soft-elastic gaskets having a passage. It is not necessary to treat both parts before to improve the tight connection.
  • the rounded end portions also ensure that even if the ribbon cable in the gasket receiving it in the lateral direction, i. in the direction of the greatest extent of its cross-section, no displacement is achieved, which leads to a leak, since the rounded end portions provide sufficient material for the effective and permanent sealing.
  • each end section is circular in cross-section and has a diameter which is greater than the thickness, and that each transition is represented by a curve of at least one circular arc with a radius which is greater than 0, 5 times the diameter.
  • the rounded end portion is approximated in cross-section of an oval shape.
  • the insulation enclosing the conductors is produced by extrusion.
  • the ribbon cable may be used in a sealing arrangement comprising a sealing element having a passage for the ribbon cable and made of a flexible material.
  • a sealing arrangement which comprises a sealing element which forms a passage for the ribbon cable, in which chambers open to the passage are provided, which are filled with a gel.
  • the passage is rectangular or adapted to the shape of the ribbon cable.
  • Figures 1 and 2 will be described together.
  • the two figures show a ribbon cable 1, wherein Figure 1 shows a portion thereof, whose longitudinal direction is designated L. It is a ribbon cable 1, which comprises in a plane 2 by far side by side arranged electrical conductors 3, which are enclosed by an insulation 4 made of a thermoplastic material.
  • the lateral longitudinal ends extending in the longitudinal direction L are designated by 8.
  • end portions 9 are formed, whose design is explained in more detail in connection with Figure 3.
  • the flat-ribbon cable 1 has a first outer surface 5 and a second outer surface 6 facing away from this, which ends in between the two end portions 9 extending at the lateral longitudinal ends 8.
  • the two outer surfaces 5, 6 are arranged at a distance from one another, forming the thickness 7, and in each case arranged in different directions at a distance from the plane 2.
  • the two outer surfaces 5 and 6 are substantially parallel to the plane 2, wherein is essentially to understand that due to the manufacturing process by extrusion variations in the thickness 7 may occur, so that differences to the other areas may be present.
  • the end portions 9 each comprise a rounded part 11 and the rounded part 11 with the first outer surface 5 and second outer surface 6 connecting transitions 10th
  • end portion 9 is formed in relation to the located between the two longitudinal ends 8 portion with the first outer surface 5 and the second outer surface 6 and the thickness formed between the two 7 thickened.
  • the end portion 9 has a rounded portion 11, which is substantially circular in shape and has a diameter 12 which is greater than the thickness 7, so that the end portion 9 of the ribbon cable 1, the passage 15 with its upper and lower shown in Figure 3 Boundary edge exceeds.
  • the rounded part 11 designed with the diameter 12 merges into the first and second outer surface 5, 6, each with a transition 10.
  • the radius 13, which connects the first outer surface 5 and the second outer surface 6 with the rounded part 11, is dimensioned so that it is greater in dimension than half the diameter 12.
  • the transition 10 may be formed by a plurality of such curves formed by radii ,
  • FIG. 5 shows a sealing element 16 which, for example, is made of silicone and has a passage 15 through which the ribbon cable 1 is passed.
  • the sealing element 16 for example, a seal between a housing of a connector 14, as shown in Figure 4 and, for example, a lid that holds the sealing element 16, and further between the ribbon cable 1 and the sealing element 16 ago.
  • Figure 6 shows a sealing element 116 as a single part, through which the ribbon cable 1 is passed.
  • the sealing element 116 forms a passage 115, which can be seen in more detail from FIG. 7, which shows a longitudinal section through the arrangement according to FIG. It can be seen that the sealing element 116, which is made for example of a silicone material, in addition to the outer surfaces and the end portions of the ribbon cable 1 facing provided with chambers 17 which are open to the passage 115 and are filled, for example with a gel for effective sealing. The gel contacts the opposing surfaces of the ribbon cable 1 and seals hermetically.
