Abstract: To provide an inexpensive board mounted connector which achieves both a simplification in structure and a reduction in size. A board mounted connector includes a fixed housing fixed to a board; connector terminals which are housed in the fixed housing and connected to a conductive portion of the board; an operating housing which is movable with respect to the fixed housing; and an elastically deformable support portion which presses, supports, and electrically connects relay terminals of electrical elements, which are inserted in the fixed housing, to the connector terminals along with the movement of the operating housing.

Abstract: In a power conversion device, a semiconductor module, a bus bar assembly, and a smoothing capacitor are superposed on a cooler in the stated order from the cooler side. At least one of a cooling column-equipped member, which is at least one of the smoothing capacitor and the bus bar assembly, and the cooler is provided with a cooling column configured to transfer heat of the cooling column-equipped member to the cooler.
