903,319. Transformers and inductors. SIEMENS & HALSKE A.G. July 20, 1960 [July 21, 1959], No. 25268/60. Class 38 (2). One or more coils 11, useful in printed circuits, are mounted between two magnetic part cores 1, 2 which are located between two plates 3, 4 held together by resilient clips such as 5. Some of the corner parts 3<SP>1</SP>, 4<SP>1</SP> on plates 3, 4 bear stub members 3<SP>11</SP>, 4<SP>11</SP> firing down to ends 31, 41 which plug into corresponding sockets in the opposite plate, thus preventing relative lateral movement. In mounting the component, stubs 32, 42 may enter holes in a base-plate. Extensions and tags such as 51, 71, 81 and 52, 72 act as terminals, and may be connected to the coils. Further strips 12, 13 are sandwiched between plate 4 and core 2, secured by bending over ends 121, 131 through holes in the plate; ends 122, 132 and bent-up strips 123, 133 are used as terminals as required. Similar strips can be added between plate 3 and core 1. A member 16 carrying a magnetic plug 17 screws into plate 3 and allows adjustment of the inductance of the coil. In a modification a U-shaped conducting strip with arms parallel to the axis may replace strips 12, 13 between plate 3 and core 1 by which the component may be secured to a chassis (Fig. 4, not shown). In a further modification, two coil structures may be mounted coaxially between plates 3, 4 held together by a single set of springs, the structures being separated by a common intermediate plate (Fig. 5, not shown).
