ABSTRACT:
The connecting device has yokes (5, 6) brazed to the winding rod ends (1, 2), and the end surfaces of the yokes have distance pieces (10, 11, 12, 13). The hollow conductors (4) protrude beyond the solid part conductors (3) and are led through brazing plates (14, 15) which are brazed to both the hollow conductors (4) and the distance pieces (10, 11, 12, 13). Caps (16, 17) are placed over the brazing plates (14, 15) and brazed to the brazing plates (14, 15) in such a way that there is no leakage of liquid. The brazing points can be inspected at any time and, if necessary, improved because of the distance between the brazing plates (14, 15) and the rod end surface. The water chambers (20, 21) formed by the brazing plates (14, 15) and the caps (16, 17) are solidly connected to the winding rods (1, 2) and to the yokes (5, 6), so that no relative vibrations, which can damage the hollow conductors, can occur. The water chambers (20, 21), which are expensive in manufacture, do not depend on the rod geometry. The whole of the variance is provided by the brazing plates (14, 15) which are relatively simple to manufacture.
