ことになる。DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 6 and 7 of the drawings. In Fig. 5, a winding 2 is wound around a coil bobbin/1, and the lead wire 6 of the winding 2 is connected to a pin terminal 3 by soldering, an iron core 4 made of a silicon steel plate is incorporated in the coil bobbin 1, and a pin terminal is connected to the coil bobbin 1. A transformer is formed by attaching an insulating protection case 11 made of a molded product having a recessed stepped portion 12 around the insertion hole 3. FIG. 6 shows a completed diagram of the transformer of the present invention. FIG. 7 shows a sectional view of the transformer shown in FIG. 6, which is mounted on a printed circuit board 9 having an eyelet 1o and connected with solder 8. The eyelet 10 fits into the recessed stepped portion 12 of the insulation protection case 11, and the insulation protection case 11 comes into close contact with the printed circuit board 9.
また、凹状の段差部１２は第８図に示すようにピン端子
挿入孔側々の周囲に別々に設けてもよい。Furthermore, the concave stepped portions 12 may be provided separately around each side of the pin terminal insertion hole as shown in FIG.
