Abstract (en)
[origin: US4375720A] Cable ends (1 and 2) are to be joined. The cables are armored by stainless steel sheaths, and have two conductors (9 & 11, and 8 & 10 respectively) insulated by means of compressed mineral insulation (14). The cables are typically for thermocouples and have an outside diameter of a few millimeters. Joining proceeds as follows: The cable ends are reduced in diameter by swaging, e.g. with initial conical portions (5,4) followed by smaller diameter portions (7,6). The ends of the swaged portions are stripped to reveal the conductors which are joined end-to-end by welding. A longitudinally slotted length of tubing (3) is placed around the join, and the tubing is filled, via its slot, with powdered mineral insulation. The length of tubing 3 is then closed by welding, and the entire join is drawn down around the join to ensure that the entire joined cable is of uniform outside diameter.

Procédé de jonctionnement de câbles blindés (1, 2) à isolant minéral comprimé, de faible diamètre. On utilise un élément de tube (3) d'un diamètre externe un peu supérieur au diamètre externe de la gaine des tubes, et muni d'une fente longitudinale. On rétreint les extrémités (6, 7) des câbles, puis en dénude une partie, on soude les conducteurs internes, met en place l'élément de tube autour de ceux-ci, reconstitue l'isolant minéral en poudre, puis comprime cet élément de tube, soude les bords de sa fente longitudinale, puis le soude sur les extrémités des gaines des câbles et étire le câble formé. Application au jonctionnement de câbles de thermocouples.
