Abstract

772,137. Transformers and inductors. SKILLMAN & CO. PTY., Ltd., T. S. Dec. 19, 1955 [Dec. 29, 1954], No. 36322/55. Class 38 (2). A clamping and mounting device for transformers or the like having a magnetic core 3 partly surrounding the windings 2 comprises two shells 4, 5, each of which wholly and closely surrounds one end of the core 3, the two shells meeting and overlapping at the middle of the transformer and finally mechanically interlocking with each other. The shells are similar to each other and each comprise an end piece 4 and two side pieces 8 which are at right angles to the end piece 4. The edges 4<SP>1</SP>, 6 of the pieces 4, 8 are bent inwardly at right-angles so that the shell when pushed over the core clamps the laminations thereof together or grips it if it is of a compacted powder construction. The edge of the shell which meets the other shell is formed with a shaped edge such as shown at 9 so that after meeting a corresponding edge and passing over it the corresponding edges finally snap back into the same plane, thereby becoming interlocked with one another. The shells may be stamped from a metal sheet or may be of a moulded plastic construction. Mounting lugs 10-13 are formed integrally with the shells. After assembly the shells may, if desired, be soldered together along the edges marked X.
