    • An electronic device includes an electronic component provided with leads. A printed circuit board has a front surface and a back surface and is provided with through holes and a groove hole. The through holes are capable of receiving the leads, respectively. The groove hole is formed so as to cross straight lines that connect the through holes. A first insulating spacer is provided on the groove hole between the leads so as to isolate the leads from each other and is positioned between the electronic component and the front surface of the printed circuit board. A second insulating spacer is inserted through the groove hole from the back surface of the printed circuit board and engages with the first insulating spacer so as to isolate end portions of the leads from each other.
    • 电子设备包括具有引线的电子部件。 印刷电路板具有前表面和后表面,并且设置有通孔和凹槽。 通孔能够分别接收引线。 凹槽形成为穿过连接通孔的直线。 在引线之间的槽孔中设置第一绝缘隔离物,以将引线彼此隔离并且位于电子部件和印刷电路板的前表面之间。 第二绝缘隔离物从印刷电路板的后表面穿过槽孔插入,并与第一绝缘垫片接合,以使导线的端部彼此隔离。
