Abstract
1,220,274. Transformers and inductors. H. LEUENBERGER. 8 Nov., 1968 [14 Nov., 1967], No. 53046/68. Heading H1T. A choke or transformer with a magnetic core having packets of core laminations 2 forming at least a pair of windows 6 comprises at least one winding (7, Fig. 2, not shown) arranged such that the portions or overhangs of the winding beyond the core are disposed as at 14 so as to abut against the core and lie against a sheet metal casing composed of a hood 3 and a base 4. Thin sheets of deformable but hard material compressed to a pre-arranged value may be placed in the air-gaps between the core packets, before the core is clamped between the baseplate 4 and the hood 3. The windings 7 may first be wound flat, assembled in the windows and then the overhangs bent as at 14, or, the windings may be preformed to the required shape. There may be two similar windings in a choke and these may be connected in series. The space between the winding overhang and the casing as well as the core may be filled with an insulating mass with relatively good heat conducting properties. The stampings of a packet of laminations are held together by projections on every lamination to fit into corresponding dents in adjacent sheets (as at 15, 16, Figs. 2 to 5, not shown). A second embodiment comprises for its core two E-shaped packets of laminations (Fig. 2, not shown) and a modification of this has an E-shaped packet of laminations and a T-shaped one to match (Fig. 5, not shown).
