Abstract
A junction box has a casing assembly including an upper casing and a lower casing, a laminated unit including bus bars and insulation plates, and first and second printed circuit boards contained in the casing assembly. The first printed circuit board is used as a higher current circuit having thick-film conductors. The second printed circuit board is used as a middle or lower current circuit having thin-film conductors with thicknesses smaller than those of the thick-film conductors on the first printed circuit board. Board relays are mounted on a part of different peripheral portions on both sides of the first printed circuit board or a part of peripheral portion of either side of the first printed circuit board. The board relays are disposed in the casing assembly to be opposed to a first heat generating element containing space defined between a front side of the first printed circuit board and an inner surface of a top wall of the upper casing, and a second heat generating element containing space defined between a rear side of the first printed circuit board and an inner surface of a bottom wall of the lower casing.
