Abstract:
1. An assembly structure for a power supply circuit unit of an electric device, comprising: a wiring substrate having a front face and a rear face opposed the front face; an electric component mounted on the front face and electrically connected to the wiring substrate at the rear face by soldering; and a protection cover comprised of a resin material and including: the electric device has housing comprised of a sheet metal and having a top board, a bottom board, a rear board and a side board which define an inside corner accommodating the power supply circuit unit having the wiring substrate and the electric component; the connecting plate of the protection cover includes a rear plate disposed between the power supply circuit unit and the rear board of the housing, and a side plate disposed between the power supply circuit unit and the side board of the housing; the connecting plate of the protection cover has a groove portion into which an edge of the wiring substrate is inserted, thereby positioning the edge in a thickness direction of the wiring substrate; the groove portion is formed by removing a middle portion in a height direction of a rib which is formed on the rear plate; a corner portion through which the rear plate of the protection cover is continued to the side plate of the protection cover is opposite to the inside corner of the housing; and the lower plate of the protection cover is disposed on the bottom board of the housing through a rib having a nonlinear shape and formed on the lower plate of the protection cover.
