Definitions

  • the present invention relates to a method for securing rods of insulating material in attachment fittings, a device for its implementation and the application of the method and the device to the insulator rods and their attachment fittings.
  • connection is very often unsatisfactory, especially because of the nature of the components to be combined, namely, on the one hand, a rod made of insulating material and, on the other hand, a metal fitting.
  • US Patent No. 3,672,712 describes a structure for securing the end of a fiberglass element to a frame.
  • the end of the fiberglass element on which the reinforcement must be secured is divided into four equal sections.
  • a central opening is provided to facilitate the introduction of resin between the sections.
  • Patent DE n ° 1.074.688 describes the joining of the ceramic or similar envelope of an insulator with a core constituted by several rods of hardened resin based on glass fibers by means of a filling material (glue) .
  • Patent CH No. 571,267 describes a method for anchoring the end of a rod of synthetic resin reinforced with fibers in a frame, method according to which the end of the rod is heated until obtaining - '' a weakening of the synthetic resin-lining fibers connection, we proceed to a widening in all directions and to the anchoring by filling the slots with the synthetic resin which hardens.
  • DE Patent No. 1,159,531 describes an insulator consisting of a ceramic shell and a core (rod) of synthetic resin reinforced with fibers of glass.
  • the space between the core and the envelope is filled with a liquid medium or in the form of a paste (glue).
  • a blocking member is applied against the rod to prevent it from rotating.
  • the object of the present invention is to eliminate the aforementioned drawbacks and it makes it possible to subject an insulator rod to an attachment fitting according to a secure, effective, very resistant and durable fixing.
  • the method according to the present invention is very simple to carry out and is very economical.
  • the method for securing rods of insulating material in attachment fittings is characterized in that it consists in introducing a rod provided with a hole and a slot intended to reduce the force necessary without causing: the spacing of the end of the rod in a fitting also provided with a blind hole, to place a fixing piece comprising a channel in the blind hole of the fitting, to make the end of said fixing part in the hole of the rod which, under the stress of the cone of entry of this fixing part, deviates and comes to be pressed on a notable portion of the periphery of the conical bore of the fitting, to proceed tamping, once this is ensured, from the inside of the fitting through the channel of the fixing piece, with a resin of high mechanical resistance, zero shrinkage and expansion coefficient identical to that of the metal constituting the fitting which, after polymerization, forms with the rod, a rigid block secured to the fitting, the undercut of which opposes the extraction of the rod even under high stresses, and to level the fixing piece flush with the fitting
  • the hole in the insulator rod is inserted into the axis and the extension of the blind hole in the fitting.
  • the fixing piece is placed in the blind hole of the fitting by continuous pressure or repeated shocks.
  • the interior of the fitting is stuffed by vacuum suction and then by injection of a resin, this resin being an epoxy resin or any similar suitable adhesive.
  • the present invention also relates to a device for anchoring rods of insulating material in attachment fittings allowing the implementation of the aforementioned method, device which comprises a rod of insulating material of high tensile strength consisting of filamentary glass / epoxy resin, a metal fitting with internal geometry ensuring a significant undercut and a third metal part of fixation...
  • FIG. 1 a top view of an insulator rod 1 provided with a hole 2 with a diameter of the order of 6mm and with a slot 3.
  • This rod l made of insulating material with high tensile strength, is, for example, filamentary glass and epoxy resin.
  • Figure 2 shows an exploded sectional view of the three constituent elements of the anchoring device of the invention for the implementation of the method.
  • the rod l provided with a hole 2 and a slot, is placed in the axis of the hooking fitting 4.
  • This fitting 4 has a blind hole 5 on one side. It is a metal fitting with internal geometry ensuring a significant undercut.
  • the diameter of the blind hole 5 can be, for example, about 10 mm.
  • the internal part of the fitting 4 has a frustoconical shape 6.
  • the third element of the anchoring device is constituted by a fixing piece 7.
  • This fixing piece 7 is a hollow pin comprising a channel 8. Its upper part 9 ′ has a diameter corresponding to that of the blind hole 5 of the fitting 4 while its end 9 is frustoconical.
  • the expression "stuffing of the interior of the fitting” means that a relatively high vacuum is first applied using any suitable means, not shown, and well known to specialists in this field. Then, after this application, a suitable resin is injected inside the fitting 4 via the channel 8. As a result, no bubbles are formed which are harmful to the joining operation and consequently the connection is very rigid and very reliable.
  • Figure 3 shows the assembled elements and the connection obtained after the implementation of the method according to the present invention. This figure illustrates particularly well the securing of the rod 1 in the attachment fitting 4 and the location of the epoxy resin 10.
  • the device for carrying out the process of the invention is of a very simple and very economical design and that the components are simply a rod 1 made of insulating material of high tensile strength such as, for example, a material made of filamentary glass and epoxy resin, a metal fitting 4 of internal geometry ensuring a significant undercut, and a metal fixing part 7. To improve the connection, the parts undergo mechanical machining.
  • the method and the device according to the present invention find a particular application for securing insulator rods to their attachment fittings; however, it is possible to envisage other applications.
