る。(Prior Art and its Problems) Conventionally, as a structure for attaching a small transformer to a printed circuit board, the structure shown in FIGS. 6 and 7 is known. FIG. 6 is a perspective view showing a state before a conventional small transformer and a printed circuit board are fixed, and FIG. 7 is a plan view of the back surface of the printed circuit board after fixing, as seen from the direction of arrow R in FIG. 6. An iron core 2 around which a transformer winding 1 is wound is held between a clamp 3, and this clamp 3 is provided with two opposing protruding legs 3a and 3b. This leg portion 3a,
3b is a mounting hole 4 provided in the printed circuit board 4
a and 4b, respectively, and protrude from the back surface of the printed circuit board 4. The protruding legs 3a, 3b are bent inward at right angles so that they are parallel to the printed circuit board 4, and the mounting surface 2a of the transformer and the legs 3
The printed circuit board 4 is held between a and 3b. Further, a copper foil portion 5a provided on the back surface of the printed circuit board 4,
5b and the outer periphery of the bent leg parts 3a, 3b are soldered to fix the small transformer to the printed circuit board 4.

点を有する。 This method of mounting and fixing poses no problem if a force perpendicular to the printed circuit board is applied to the small transformer, but
When a force parallel to the printed circuit board is applied, the force is received by the soldered portion S around the outside of the bent portions of the legs 3a and 3b, resulting in a lack of strength. That is, when a force in the direction indicated by the solid arrow T in FIG. The structure is such that there is a gap in consideration of machining errors, so
The soldered portion S receives the force applied to the small transformer. However, in FIG. 7, only the soldered portion S indicated by B faces the direction of the force applied to the small transformer, that is, the force applied to the legs 3a and 3b, and the other soldered portions S face the direction of the force applied to the legs 3a and 3b. It has the disadvantage of lacking strength because it is supported by the adhesive force of the solder.
