Abstract

PURPOSE: To simplify the manufacture of a small transformer for electronic equipment by adhering a magnetic core in which the center part of long sided winding leg is severed to both sides of molded spool which holds a wound coil and by using elastic holding pieces to unite.
CONSTITUTION: Two spools 1 and 2 are arranged face to face and brims 1a and 2a which are linked by engaging with concave and convex parts are fitted to both ends of the spools 1 and 2 respectively and two L-shaped engaging pieces 3 and 4 are formed respectively at the upper and lower parts of the outside of the brims 1a and 2a. Then, the fixed windings are wound over the spools 1 and 2 and along the brims 1a and 2a and the extruded part of U-shaped magnetic cores 7 are respectively adhered to the surface of the brims 1a and 2a exposed between engaging pieces 3 and 4 by adhesive. Then, elastic holding pieces 5 are held to the rear side of the magnetic cores 7 and the upper and lower pressure pieces 6 which are provided in the holding pieces are fitted to the opposite engaging pieces 3 and 4 to unite the winding and the iron cores 7.
