Definitions

  • the object of the present invention is to provide sealing an end connection of a flat conductor, made in particular in the form of a flat tubular braid.
  • flat braids of this type are used to put at the same potential, in particular to the earth, junction screens of high voltage electric cables.
  • junctions to be perfectly insulated and waterproof, means should be provided sealing also for the connection of the end of these flat shape conductors.
  • three flat braids are used which must be connected to an earth cable.
  • the object of the present invention is to eliminate these disadvantages and significantly improve the tightness of a flat conductor end connection, made in particular under the shaped like a flat tubular braid.
  • the sealing device of an end connection of flat conductor, tubular includes a sealing and protection sleeve connection made of a cold shrinkable material enclosing the connection.
  • the device further comprises a rigid core, of convex external surface, arranged at inside the end of the tubular flat conductor, the assembly consisting of the end of the tubular flat conductor and the rigid core surrounded by said end, being enclosed by the sealing and protective sleeve.
  • the flat conductor or the tubular flat braid is preferably covered with an insulating protective sheath which is capable of deform when inserting the rigid core.
  • the rigid core can advantageously have a shape cylindrical exterior. It can be produced in the form of an insert less partially hollow, for example in the form of a tube.
  • the core rigid can also be a solid element such as a bar.
  • its end can be tapered or rounded.
  • the sealing device according to the present invention can be used to seal any end connection of flat conductor.
  • a particularly interesting application of the invention allows the realization of a waterproof glove with one or more fingers, for the connection of several ground braids to a ground cable of a equipotentiality device for screens at a junction of electric cables high voltage.
  • the sealing device of the invention is suitable for a flat conductor produced in the form of a tubular braid 1 of which the end 1a has been shown diagrammatically sectional.
  • the tubular braid is covered with an insulating sheath 2 generally made of synthetic material with a certain elasticity which allows a deformation as we will see later.
  • the braid in itself is made up of electrically conductive wires, for example copper wires, which have been braided into a tubular form and then flattened so as to take the flat shape visible in FIG. 1.
  • a rigid core 4 which in the example illustrated in the Figure 1, a generally cylindrical shape of circular section, is produced in rigid synthetic material constituting a solid insert.
  • This nucleus 4 was threaded inside the end 1a of part 3 of the flat braid tubular which surrounds, as shown in 3a, the periphery of the core 4.
  • An empty space 5 remains between the core 4 and the braid part 3 of flat shape, this space 5 being located in the zone where the braid passes from the flat shape to cylindrical shape 3a.
  • the core 4 can also be produced under the shape of a hollow tube, insofar as the resistance of the tube is sufficient to withstand the pressure exerted by the retractable sleeve 6.
  • the core 4 can also be made of metal or any other material.
  • the end of the latter can be tapered or rounded, thus occupying at least part of the space 5.
  • a conductor is in the form of a flat tubular braid 1 covered with a insulating protective sheath changes from flat form to form substantially cylindrical thanks to the insertion of a rigid core not visible in Figure 2, the assembly being enclosed by a sleeve 6 which provides sealing and protection.
  • three flat conductors 1 are are connected by means of a sealing device according to the invention produced in the form of a glove 7 with three fingers 6, the assembly being constituted by a cold shrinkable material which provides sealing and protection of the connection.
  • the present invention thus allows in a simple manner to obtain an excellent seal for the end connection of a tubular flat conductor and in particular a conductor in the form of a flat braid.
