Definitions

  • the present invention relates to a method of joining shielded cables of small diameter with compressed mineral insulator, in particular thermocouple cables.
  • the object of the present invention is to enable two shielded cables with compressed mineral insulation to be welded to the end, avoiding any excess thickness at the junction, and obtaining a junction having a mechanical resistance little different from that of the initial cable; it also aims to ensure the continuity of the conductors and to maintain the dielectric characteristics of the initial cables.
  • Welding operations are preferably carried out with an arc under inert gas without filler metal.
  • the shrinking of the ends of the cables to be joined is preferably carried out according to an angle cone at the apex approximately 20 °.
  • thermocouple cables of the kind sold by the applicant under the brand name "Pyrotenax”.
  • the two cables to be joined 1 and 2 each 3 mm in diameter, each include two conductors made of nickel-chromium alloy and alloyed nickel, a sheath of stainless steel and a mineral insulator formed by magnesia.
  • a tube element 3 with a slightly larger diameter, for example 4 mm, length 20 mm is prepared which is split longitudinally between two generators spaced about 1 mm apart (not shown). .
  • the ends 6, 7 of the cables are shrunk to a final diameter of approximately 1.6 mm, with a shrinkage cone angle 4.5, of 20 °, over a length close to 15 mm.
  • the ends are stripped over 5 mm in length.
  • the junction tube element is put in place around the ends of the sheaths, and is temporarily held in place by pointing by arc welding under inert gas.
  • the mineral insulation 14 is then reconstituted in the junction zone by introducing the powdered insulation through the slit of the tube element until it is filled. Then the slot is closed by exerting on the tube element a radial compression and welding its edges with an arc under inert gas without filler metal.
  • a final welding or brazing of the edges of the tube element is then carried out on the cable sheaths and the remaining gaps are filled with solder 15, 16.
  • junction area to a drawing pass so as to calibrate it to the initial diameter of the cables.
  • thermocouple cable junction thus manufactured a tensile strength of approximately 80% of that of the initial cable when the ends of the cable element were welded on the cable sheaths, and of approximately 50 % of that of the original cable when they were brazed.
