Definitions

  • the present invention relates to a method of connecting the end fin of an insulating element comprising an insulating rod surrounded by fins made of vulcanized elastomer with an end fitting. It relates in particular to organic electrical insulators.
  • German patent application DE-A-2 855 211 it is also known from German patent application DE-A-2 855 211 to use a seal and a silicone grease.
  • the bonding method according to the invention is characterized in that a layer of rubber / metal bonding agent is placed on the lower part of the fitting, then there is between fitting and end fin an elastomeric intermediate crown in the raw state, the fitting is fixed to the rod so that the intermediate crown is compressed between the end fin and the lower part of the fitting and the intermediate crown is then vulcanized.
  • the elastomer seal after vulcanization retains its seal over time and expands during the tensile forces imposed on the insulating element without loss of this seal.
  • the insulating element 1 comprises an insulating rod made of composite glass fibers 2 surrounded by an elastomer sheath 3 in the raw state.
  • each fin 4 comprises an upper sleeve 5, a lower sleeve 7 and a peripheral part 6 forming an obtuse angle with the upper sleeve 5 and an acute angle with the lower sleeve 7.
  • Such an insulating element 1 is for example described in the document FR-A-2 461 343.
  • a foam crown 9 is then placed around the rod 2 which is placed on the edge of the upper sleeve 5 of the terminal fin 4 as well as on the edge of the sheath 3.
  • the lower part 12 of a fitting 13 is applied to this crown 10, this part 12 having been previously coated with a rubber / metal bonding agent.
  • This bonding agent allows during subsequent vulcanization the bonding of the elastomer on the metal.
  • the crown 10 is applied perfectly on the part 12 of the fitting 13 even if the surface of the fitting has many irregularities.
  • the fitting 13 has a cylindrical internal wall 14 contiguous to the lower part 12 which tightly traps the upper sleeve 5 of the terminal fin 4 and the crown of foam 9.
  • the fitting then comprises a first conical surface 15 which starts from the cylindrical wall 14 to approach the rod 2 then a second conical surface 16 which departs from the rod 2.
  • the fitting 13 being pressed strongly on the crown 10 the cavity is filled between the surfaces 15 and 16 and the rod 2 of polymerizable resin.
  • the rod 2 After polymerization of the resin, the rod 2 is thus sealed in a biconical volume 17, so that when tensile forces are imposed on the fitting 13, these will be communicated to the rod 2.
  • the insulating element 1 with its fitting 13 is then brought to the vulcanization temperature. All the elastomer in the raw state is vulcanized and the crown 10 becomes a tight seal between the fitting 13 and the terminal fin 4 which when the insulating element 1 is subjected to tensile forces expands without losing its characteristics d sealing.
  • the raw elastomer used is preferably EPDM, the vulcanization temperature of which is of the order of 140-160 ° C.
