Abstract
An electrical junction box comprising a case having a rib; a wiring board assembly provided in the case and comprised of an insulating board and a plurality of bus bars mounted on the insulating board, the bus bars being sandwiched between the insulating board and the rib of the case; and a drainage channel provided near the bus bars. The drainage channel comprises a cutout of the rib formed at a portion bridging the adjacent bus bars. With this structure, the water having entered the case is prevented from staying in this portion, so that it may smoothly flow through the cutout of the rib to the outside of the case. Accordingly, the generation of short circuits between the adjacent bus bars may be prevented. At least a through-hole may be formed through the insulating board at a position near the bus bars, and a gap may be defined between the bus bars and the insulating board by providing a plurality of projections on the insulating board.
