Abstract

1464798 Inductors and transformers W ZUMTOBEL 16 Aug 1974 [20 Aug 1973] 36223/74 Heading HIT A transformer or choke comprises an iron body 5.1, having a shell part 5.2 and a core part 5.4 carrying a coil, and a support body 5.6 on which the iron body is mounted and fixedly connected by welding, wherein in the region of the weld 5.7 the surfaces of the iron body and the support body lying on either side of this welding, lie flush with one another (Fig. 10, not shown). The laminated core part may be T-shaped or H-shaped and the iron body may be mounted such that there is a gap between it and the support body. The shell part consists of strip-type lamellae which may be U-shaped, E-shaped or 0-shaped. The support body may be a flat plate with or without turned-up edges or cover the shell on two sides or three sides. The support body may be provided with elongated slots or recesses (20), Fig. 11 (not shown), to accommodate fixing screws. A central longitudinally extending incision (21) may also be provided. The welding may be in the form of spot or line welds.
