Definitions

  • the present invention relates to a flat cable comprising at least two conductors embedded in an insulating sheath.
  • a flat cable comprising at least two conductors embedded in an insulating sheath.
  • Such a cable is known from document DE-A-2 811 452.
  • the insulating sheath and, if necessary, the peripheral insulation of the conductors can be perforated by means of an appropriate device, and devices such as sockets, switches, etc. can be connected directly through these perforations via insulation displacement contacts.
  • Document DE-A-2 811 452 describes a flat cable comprising an insulating sheath having at the ends coupling means allowing a winding of the cable on itself to obtain a tubular shape. Such a tube does not have sufficient rigidity for passage and introduction into a cylindrical conduit.
  • the object of the invention is to facilitate the passage of cables in conduits.
  • the flat cable according to the invention comprising at least two conductors encased in an insulating sheath, which is equipped with coupling means arranged on its lateral edges, these means being arranged to removably link said lateral edges when they have been previously juxtaposed following a winding of the cable on itself around its longitudinal axis
  • the insulating sheath comprises tubular channels for housing the conductors, and flexible ports for connection between the channels, is characterized in that said channels each comprise a series longitudinal ribs and grooves formed on one of the faces of the cable, the ribs being arranged to engage in the corresponding grooves when the cable is wound on itself around its longitudinal axis.
  • said means comprise at least a first element disposed on one of said lateral edges of the cable and at least one second element disposed on the other of said lateral edges of this cable, these two elements comprising members additional attachment.
  • the flat cable 10 comprises for example three conductors 11, 12 and 13 cylindrical surrounded by an insulating field 11a, 12a, 13a respectively in the form of a sheath of annular section.
  • These insulated conductors are coated in an insulating sheath 14 which comprises coupling means arranged on its lateral edges to allow, as shown more particularly in FIG. 2, to link these edges in a removable manner when they have been previously juxtaposed by winding the cable on itself around its longitudinal axis.
  • Said sheath 14 actually comprises tubular channels 14a, 14b and 14c, the number of which corresponds to that of the conductors 11, 12 and 13, each of the latter being housed in one of said channels. These channels are linked two by two by flexible bridges 15 whose thickness is significantly reduced compared to that of the channels, in order to facilitate the winding of the cable on itself.
  • the coupling means advantageously consist of a first element 16 disposed on one of the lateral edges of the sheath 14 and of a second element 17 disposed on the other lateral edge of the sheath 14.
  • the first element 16 comprises a fastening member 16a having a hook-shaped profile which forms part of or constitutes said element and the second element 17 comprises a fastening member 17a comprising a recess in which the fastening member can be embedded hanging 16a.
  • FIG. 2 clearly shows how said attachment member 16a engages in said attachment member 17a to ensure the connection of the lateral edges of the cable, when the latter has been wound on itself as mentioned previously.
  • these conductors can be electrical conductors or light conductors. Finally, they can be naked or isolated. In the embodiment described, these conductors are doubly insulated since they are coated in an insulator of annular section, itself coated in the insulating sheath 14.
  • Figures 3 and 4 show the cable of the previous figures in the two states in which it is intended to be used, namely an unwound state, corresponding to a conventional use of a flat cable and a coiled state facilitating insertion into a tubular conduit.
  • the sheath 14 has a smooth face and a face provided with longitudinal ribs 18 separated by grooves 19. These ribs and these grooves are provided to define the relative positioning of the channels 14a, 14b, 14c when the cable is in its state wound, as shown in Figures 2 and 4.
  • the ribs 18 engage in the grooves 19, which helps to maintain the channels 14a, 14b and 14c and therefore the conductors 11, 12 and 13 in a stable position and perfectly defined inside the coiled sheath 14.
  • the attachment means can come in various variants. They can be continuous or discontinuous along the lateral edges of the sheath 14. In the case where they are discontinuous, they may include protuberances and regularly spaced cavities, the protrusions being arranged to engage in the corresponding cavities to produce a coupling of the press-button type. This coupling can also be carried out by means of adhesive substances. Finally, we can consider the use of hooking surfaces with miniature hooks and loops of the Velcro® type.
  • FIG. 5 represents a sectional view of a flat cable in which are represented by way of examples, various embodiments intended for various uses.
  • a coaxial cable 20 which is similar to that described above, are housed a coaxial cable 20, a telephone cable 21 with four twisted pairs and an optical cable 22 with two optical fibers. It is understood that these different cables can be found alone in a sheath 14 or in combination as shown.
  • the sheath can be provided with an integrated metal braid 23 which constitutes an almost integral shielding of the flat cable when it is brought into its wound state.
  • the flat cable 10 becomes a multifunction cable which lends itself well to automated connection operations while being suitable for conventional laying in cylindrical conduits.
