Furthermore, the electrical connection between the strip conductive and the cable is usually placed so that the length cable is reduced. So for a given vehicle, for example, the position of the connection to the glazing is imposed by the location of the cable in the body bay.
  • the imposed position of the connection can correspond to a curvature glazing, it can then be difficult to make the electrical connection. Through elsewhere, the imposed position of the connection does not always correspond to that elements requiring this electrical connection. It is then necessary to connect these two positions with a conductive strip, based on silver paste, for example. This conductive strip is not very aesthetic. In addition, the material used is generally expensive.

Of preferably the electrical connection is close to the accessories supplied with electrical signals. It is, for example, located, for a heated rear window, on the side of the glazing intended to be mounted in a amount, preferably in the center on this side. Because of this, the length of the conductive strip, based on silver paste for example, is thus limited. Her presence can be advantageously eliminated.
  • the cable of the invention can be fixed on the surface or on the edge of the substrate. It can be located within an area protected from solicitations external, for example within the so-called sealing zone, delimited by a seal. It can also be located outside this sealing zone.

  • a bellows 75 may also be provided to guide the cable (s) in zone C to the desired location, usually to a signal source electric.
  • the part 74 is fixed to the substrate by an anchoring mechanical between part 74 and coating 65.
  • Figure 14 shows a section along line I-I of the insert 74 described in figure 13.
  • the electrical connections are represented here under form of four cables 69, 70, 71 and 72.
  • These four cables are made up a conductive wire 79, itself made up of conductive filaments, not shown, each wire 79 being coated with a sheath 80.
  • This is, for example, of a standard sheath marketed with the lead wire.
  • several insulated wires can be coated with the same sheath 80.
  • Part of these cables 69, 70, 71 and 72 is embedded in an insert 74.
  • This part 74 is made of a thermoplastic or thermosetting material having watertightness, or even a satisfactory saline atmosphere.
  • the material is a thermoplastic or thermosetting elastomer chosen, by example, in the following group: polyvinyl chloride, polyurethane, mixture of polyurethane and polyamide, rubber, in particular of the type EPDM (Ethylene Propylene Diene Monomer).
  • This piece is, for example, molded around part of cables 69, 70, 71 and 72. The presence humidity between the cables and the material constituting the part 74 is thus avoided.
  • the part has a bulge, here represented under form of a flange 81 in order to ensure its fixing to a glazing by a mechanical anchoring.
  • Mechanical anchoring can also be ensured by a recess, a projection, a recess, a stop, etc ... and their part complementary respectively.
  • the cables are shown here coated with a sheath. It can be a standard sheath, for example made of polyvinyl chloride, or a sheath 17, 35, 36 as shown, for example, in Figures 2, 6 and 7. They can also be, at least partially, devoid of this sheath in function of the intended use.
  • the four cables can also be gathered in the same sheath, not shown, at their exit from the room reported 74.
  • Figure 15 shows a sectional view, along line II-II, of Figure 13.
  • the coating 65 is attached to a flange 81 secured to the part 74.
  • the cables 69, 72 are shown here covered with a part 65, so that the cables 70 and 71, connected to a signaling light 20, are not covered with such a room. They can be optionally coated with a sheath 17, 35, 36. It can be seen in this diagram that the part 74 is not in contact with the substrate 83, avoiding the presence of an excess thickness on this latest.
  • the auxiliary part 65 has a constriction 82 intended to hang onto the flange 81.
  • the part 65 is fixed to the substrate using, by example, an adhesive layer or an adhesive tape not shown.
  • FIG. 16 represents different variants, in section, of the part reported 74 according to the invention.
  • Part of the cable here made of a wire, is embedded in a part 74 according to the invention.
  • this part includes a flange 81 to which a coating 65 and a base 85 are attached to it.
  • the two parts 65 and 85 are on the same face of the substrate 83.
  • the substrate 83 may be optionally coated with one or more layers, not represented (s). These parts can also be on both sides opposite of the substrate 83.
  • the base 85 is, for example, a base fixed on the substrate and supporting the link 84. This base makes it possible, in particular, to get rid of any differences in geometry of the glass sheet.
  • the room 74 is not in contact with the substrate 83.
  • the piece 74 can be fixed using a bulge 86 and by a tab 87 fixed to the glass sheet (diagram 16b).
  • Bulge 86 and leg 87 can be on the two opposite faces of the substrate 83 (diagram 16b) or on the same face (diagram 16c).
  • Part 88 of part 74 can also be fixed on the substrate (diagram 16d).
  • This part fixed to the substrate may possibly have a smaller thickness to ensure the passage of the connection under the joint sealing 89.
  • the connection ensuring this passage, 90 is then preferably a conductive layer, a copper strip, a foil and / or a copper plate of the type used in printed circuits.
  • a cable 91 can possibly provide the electrical connection in the area enclosed by joint 89.
  • FIG. 17 represents a profiled insert 74 comprising a lip 92 making it possible to ensure the continuity of a lip, not shown, also secured to a mounting joint.
  • This unrepresented lip ensures protecting, centering and maintaining the glazing for the time necessary to the grip of the adhesive bead 93 fixing the glazing to the bay 94 of the bodywork.
  • the glue bead 93 can possibly seal the glazing / opening.
