Definitions

  • the present invention relates to a method for manufacturing an organic insulator according to the preamble of claim 1.
  • the rod is first coated with an insulating sheet, and the ends are provided with reinforcements, before that we perform overmolding.
  • Two rings forming part of the mold ensure the spacing of the reinforcements for the future coating and a separation between the molding mass and the reinforcements.
  • the ends of the rod are inflated by injecting a curable resin into each frame.
  • the temperature of the molding device is of the order of a few hundred degrees Celsius depending on the insulation used, for example 200 ° C; the parts of the steel molds, the reinforcements generally of aluminum or the like, and the rod in glass fibers, expand in a different way, and this results in stresses on the rod and on the reinforcements which may be the cause of subsequent degradation of the quality of the anchoring of the reinforcements.
  • the object of the present invention is to implement a method making it possible to avoid these drawbacks.
  • Such a method is economical because it implements a simple molding device, and does not involve any delicate operation of positioning in the mold of the rod and its reinforcements; in addition, it avoids the appearance in the insulator of the mechanical stresses mentioned above and it provides good resistance to humidity.
  • the previous operation can be carried out at a moderate temperature, for example of the order of 100 ° C, allowing easy handling of the various elements.
  • the seal 5 is firmly applied against the shoulder 4 and seals the cavity 3.
  • the frame 2 has two holes communicating the cavity 3 with the outside.
  • the orifice 20 is used for the introduction of a sealing material, while the orifice 21 is used for the evacuation of the air. After filling the cavity 3, it is screwed or force-fitted into the orifices of the closure caps not shown. Note that it is also possible to carry out the filling operation when the armature has a single orifice.
  • a sealing material of the compound, charged epoxy, polymerizable under such temperature conditions could be used.
  • any other equivalent sealing method can be considered.
  • connection between the rod 1 and its frame 30 can be achieved by shrinking after leaving the mold.
  • the frame has been referenced 30 before the necking shown diagrammatically by the arrow 100, and 30 ′ this same frame after necking.
  • the seal 35 is strongly compressed in 35 '.
  • Such a method includes a phase of pre-shrinking the collar of the reinforcement on the seal 5 to further improve the seal before molding the coating 13; it ends with a sealing of the rod in the reinforcement using a sealing material.
