Patent ID: 7785117

Claim:
A printed circuit board, comprising: a substrate; a connector housing mounted on the substrate; positive and negative high voltage terminals having lead wires of which one ends are projected away from a sidewall of the connector housing, folded toward the substrate, and connected to the substrate; low voltage terminals interposed between the positive and negative high voltage terminals, one ends of lead wires of which being projected from the sidewall of the connector housing and connected to the substrate, said low voltage terminals being isolated from the positive and negative high voltage terminals; first insulating walls projected from a lower case and interposed between the positive and negative high voltage terminals; slits respectively interposed between the positive high voltage terminal and the low voltage terminals, and between the negative high voltage terminal and the low voltage terminals; and a pair of cases for clipping and receiving the substrate, wherein the first insulating walls are so formed on one of the cases away from the connector housing as to be inserted into the slits, wherein the first insulating walls are projected further away from the connector housing than the folded parts of the projected lead wires of the positive and negative high voltage terminals, wherein the first insulating walls are inserted into the slits and projected from the substrate, and wherein the slits are formed further away from the connector housing than the positive and negative high voltage terminals.
