Abstract:
1. An electrical junction box comprising: a housing, wherein the housing includes housing electrical components; a power distribution board composed of a first plurality of bus bars disposed along a first insulating substrate, wherein the power distribution board is positioned in the housing, and the power distribution board is connectable to the housing electrical components; a control circuit board installed in the housing in such a way as to be perpendicular to the power distribution board; the control circuit board including an electronic circuit constructed on a second insulating substrate; control circuit electrical components mounted on a first side of the control circuit board and controlled by the electronic circuit; a bus bar circuit including a second plurality of bus bars and bonded, via a first insulative bonding layer, to a second side of the control circuit board, wherein the second plurality of bus bars include tips bent perpendicular to a body of the control circuit board, and have tab pieces formed at the tips to connect to the power distribution board; and a heat dissipating portion which is bonded to a second insulative bonding layer, to dissipate heat from the control circuit board, wherein the second insulative bonding layer is bonded to the second side of the control circuit board.
