Abstract
1,187,738. Transformers and inductors. STANDARD TELEPHONES & CABLES Ltd. 14 Nov., 1968, No. 53992/68. Heading H1T. A magnetic cored coil structure includes two magnetic core members 1, 2 which provide a primary magnetic circuit and define a winding space 15 in which a coil (not shown) is positioned on at least member 1 (e.g. on a central hollow boss 3); and terminals 17 secured by insulating material 18 to member 1. The surface of the core member on which the coil is wound is coated with insulation 16. A tubular magnetic adjuster slug 9 is fastened to a self-tapping screw 8 which engages an insulating plastics nut 11 and has a head which is surrounded by an insulating head 10 which provides frictional engagement with the wall of a central bore 6 in the member 2. (An adjuster assembly of this kind is described in Specification 1,090,028.) The slug 9 may be moved longitudinally in the bores 6 and 4 in order to adjust the reluctance of the air gap 7 between members 1 and 2. The magnetic core members may be made of ferrimagnetic material (e.g. ferrite) or of compound powders of iron or nickel-iron alloys. A method of assembling the structure is disclosed. The insulating material may be epoxy resin filled for increased strength or colour coding; and the terminals may extend out of the moulding for insertion into a printed circuit board.
