Abstract
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.
Claims8
An electronic device comprising:
- an electronic component provided with a plurality of leads;
- a printed circuit board having a front surface and a back surface opposite to the front surface and provided with a plurality of through holes and a groove hole which pass through the printed circuit board from the front surface to the back surface, the plurality of through holes being capable of receiving the plurality of leads, respectively, a number of the plurality of through holes being equal to a number of the plurality of leads, the groove hole being formed so as to cross straight lines that connect the through holes;
- a first insulating spacer provided on the groove hole between the leads so as to isolate the leads from each other, the first insulating spacer being positioned between the electronic component and the front surface of the printed circuit board;
- and
- a second insulating spacer that is inserted through the groove hole from the back surface of the printed circuit board and that engages with the first insulating spacer so as to isolate end portions of the leads from each other.
A power converter used at a rated voltage of 200 V or more, comprising:
- an electronic component provided with a plurality of leads;
- a printed circuit board having a front surface and a back surface opposite to the front surface and provided with a plurality of through holes and a groove hole which pass through the printed circuit board from the front surface to the back surface, the plurality of through holes being capable of receiving the plurality of leads, respectively, a number of the plurality of through holes being equal to a number of the plurality of leads, the groove hole being formed so as to cross straight lines that connect the through holes;
- a first insulating spacer provided on the groove hole between the leads so as to isolate the leads from each other, the first insulating spacer being positioned between the electronic component and the front surface of the printed circuit board;
- and
- a second insulating spacer that is inserted through the groove hole from the back surface of the printed circuit board and that engages with the first insulating spacer so as to isolate the end portions of the leads from each other.
