でプリント基板にトランスを固定するものである。Conventional configurations and their problems In recent years, in small transformers for electronic devices, in addition to providing pin terminals to rationalize the wiring and make them independent by soldering them to the printed circuit board,... A type of transformer is used in which a screw insertion hole is provided in the case and the transformer is fixed to a printed circuit board or the like using screws. The structure of a conventional example of such a transformer is shown in FIGS. 1 and 2. FIG. 1 is an external perspective view of the transformer, and FIG. 2 is an exploded perspective view thereof. In these figures, (1) the outer shell of the transformer with the I''i screw insertion hole (2), (3) the gutter several pin terminals, and the pin terminal (3) the transformer winding bobbin (4). ), and the primary winding (6) and secondary winding (7) are respectively wound around the bobbin (4).
) is connected to the leader line. (8) is a U-shaped insulating case, (91-ke E-type iron core, αd is I-type iron core, winding wound on bobbin (4) +61. Fit the E-type iron core (9) to the bobbin (4) from the side of the case (8), and attach the D-type iron core α0 to this.
A transformer is formed by combining the two and inserting the whole thing into the outer shell (1). When used, the pin terminals (3) are inserted into holes made in the printed circuit board and soldered to the wiring on the board. Then, the transformer is fixed to the printed circuit board using screws pushed through the screw insertion holes (2).

という欠点がある。In a conventional transformer with such a configuration, an insulating case (8
), it requires an outer shell (1) with holes for screw insertion, which increases the price, and since the outer shell (1) is simply fitted to the insulating case (8), When fixed to a printed circuit board with screws, the bobbin (41) has a disadvantage in that its strength is weak.

However, the insulating case is fixed to the bobbin by the iron core fitted to the bobbin from the outside of the insulating case, and the outer shell (1) having the screw insertion hole (2:) in the conventional example is omitted, and the bobbin is connected to the insulating case. It is designed to ensure that it is attached to the printed circuit board so that it does not come off.
