構造。 In a fixing structure for fixing a transformer to a printed circuit board using a ferrite core made by facing a pair of cores facing each other and joining them together, one end of a U-shaped spring tightens the outside of both cores of the transformer to fix them together. It is bent outward to form a fixing shaft, and the printed circuit board is provided with an insertion hole for the fixing shaft.
A fixing structure for a transformer, characterized in that the fixing shaft is inserted into an insertion hole, and a push nut is attached and fixed to the fixing shaft protruding from the back side of a printed circuit board.
