１次側と電気的に接続する。A plug blade 4, which has a notch in the rear end connection part and a protrusion at its tip, is press-fitted into the printed circuit board 2 and fixed by soldering, so that the transformer 10 can be connected to the plug blade connection part 6.
Connect electrically to the primary side.
第３図ａｌｂｌ第４図ａ、ｂにプラグ刃接続部６の拡大
図を示す。第３図ａ、ｂのものはプラグ刃４の後端部に
切り込みを入れその先端部に弓状の突起を設けたもので
ある。FIG. 3 albl and FIG. 4 a and b show enlarged views of the plug blade connection portion 6. The plug blades shown in FIGS. 3a and 3b have a notch formed at the rear end of the plug blade 4 and an arcuate protrusion at the tip thereof.
その突起部分のクリアランスｂをプリント基板２の厚み
ａよりも小さくする事により、プリント基板のプラグ刃
取付孔１４に圧入する事が出来機械的にも固定される。By making the clearance b of the protruding portion smaller than the thickness a of the printed circuit board 2, it can be press-fitted into the plug blade attachment hole 14 of the printed circuit board, and it can be fixed mechanically.
さらに半田１３にて半田付すれば、トランスの１次側の
ピン１２とは電気的に接続する事が出来る。Furthermore, by soldering with solder 13, it can be electrically connected to the pin 12 on the primary side of the transformer.
第４図ａ、ｔ）のものは、プラグ刃４の後端切り込み部
