专利说明:
2. A method according to claim 1, characterized in that the welding is carried out by arc welding in an inert gas atmosphere without a welding material. 3. The method according to claim 1 or 2, characterized in that the reduction by forging the ends of the cables to be connected is tapered with an angle of inclination 20. The invention relates to electrical engineering, in particular, to methods of connecting shielded cables of small diameter with insulation of extruded mineral material, in particular cables of thermocouples. There is a known method of connecting shielded cables, in which the ends of the inner conductors and then the sheaths L are butt-welded. However, at the level of the joint there remains a thickening, which can be a serious obstacle to the installation of the cable, jamming in the through holes, and is a weak point that can cause a failure under the influence of a significant mechanical load. The closest PB of the technical essence and the achieved effect to the proposed is a method of connecting shielded small diameter cables, which consists in removing the sheath from the cable end sections, marking the end of the internal wiring, connecting the internal wiring with butt welding, placing the junction in. A tubular metal element, the diameter of which exceeds the diameter of the cables to be connected, is not inserted into the insulating powdery mineral material into the tubular element through an opening in its wall,. tight connection of the tubular element with cable sheaths by sealing the opening and machining the resulting assembly with a wire to reduce the transverse dimensions fzj. However, this method does not allow to obtain a junction without thickening. The aim of the invention is to expand the use by eliminating thickening. The goal is achieved by matching the method of connecting shielded small diameter cables with insulated compression blowjob material 1) enclosing the sheath from the end sections of the KOB cables, marking the ends of the inner conductors, joining the inner conductors by butt welding, placing the junction in a tubular metal ohm element with a diameter greater than the diameter of the connecting cables, introducing insulating powdered mineral material into the tubular element through the opening in its wall, tightly connecting the tubular element with cable sheaths, closing the opening with welding and machining the resulting assembly with a drop to reduce the transverse dimensions , use a tubular element with an aperture made in the form of a longitudinal slot, having an external diameter, in which, during compression of the tubular element in the radial direction Before the edges of the pro- longitudinal slit come together, the diameter of the tubular element corresponding to the diameter of the cable is obtained; before removing the shell, the ends of the cables to be connected are reduced by forging to a diameter smaller than the inner diameter of the tubular element; the shell is removed by a length shorter than the length of the forged ends of the cables, install the tubular element, fix it on the ends of the cables by welding at several points and after inserting the insulating powdery mineral material inside the tubular element and the latter is compressed in the radial direction to a level closer to the longitudinal edges of the slit, the slit is closed by welding and after performing sealing compound
