Abstract
PURPOSE: To reduce remaining output by forming narrow magnetic paths in several places in the circular magnetic core, while placing shields made of circular magnetic body concentrically to the magnetic core.
CONSTITUTION: Laminated circular magnetic core 1 is housed in magnetic-core housing body 2. This is wounded by secondary winding 4 and housed in insulating tape or transformer-housing body 5 with varnish or synthetic resins used as fillings 6. In the center of transformer housing body 5 is formed a window 7, through which a pair of primary lead wires 10 coated by insulator 11 pass. In the magnetic core 1 is formed hole 9 (plural places are admitted), which is arranged so that all the magnetic cores be placed on the same center. Moreover, circular shielding flat plate 3 is provided in the fillings 6. Because hole 9 forms the narrow part of magnetic flux and shielding plate 3 screens unnecessary magnetic flux, generation of remaining output can be prevented.
