<p>PURPOSE:To prevent the transmission of beat and to ground a core by inserting flat-shaped elastic bodies with insulating property through which a conductive metal needle is piereced, between a metal fitting and the core. CONSTITUTION:A rectangular core is constructed by connecting U-shaped cores 1 and 2, and a coil 3 is attached to the core. Metal fittings 6 and 7 are contacted to the cores 1 and 2 by way of intervening flat-shaped elastic bodies 4 and 5 with insulating property and are tightened with a screw 8 and nuts 9 and 10. A conductive needle 11 is pierced from one side to the other side of the elastic body 4 in contact with the metal fitting 6 which is attached to a chasis, and the protruded portion is bent so as to constitute a part which is in contact with the elastic body 4. When the screw 8 and the nuts 9 and 10 are tightened, the metal needle 11 contacts with the metal fitting 6 and the core 1, whereby the core 1 can be grounded by way of the metal fitting 6.</p> |
