カバーの共通化が図れる等の効果がでる。Effects The present invention can reduce the potential difference by removing the portion of the printed wiring board with the maximum potential difference, and reduce the number of parts on the printed wiring board, as well as reduce the number of parts between the output terminal (or relay terminal) and the arcing protection resistor. As a result of covering the periphery of the connecting portion with insulating resin, the insulation distance from the periphery can be considered as through-insulation of the insulating resin, and the distance can be reduced. Further, by using a relay terminal, effects such as the ability to share the mold block manufacturing process and the insulating cover for the output terminal type and lead wire type can be achieved.
