PURPOSE:To realize a power supply apparatus wherein a soldering operation for a power supply transformer which is heavy and a wire material existing between a printed wiring board on the primary side and a printed wiring board on the secondary side are eliminated by a method wherein the printed wiring board on the primary side and the printed wiring board on the secondary side are connected by the power supply transformer itself. CONSTITUTION:Individual terminal pins 1a, 1b for a power-supply transformer are connected respectively to primary connectors 2a soldered onto a printed wiring board 2 on the primary side and to secondary connectors 3b soldered onto a printed wiring board 3 on the secondary side. Thereby, the power supply transformer itself acts as a connecting medium, a soldering operation for the power supply transformer which is heavy and wire materials which existed between the printed wiring board on the primary side and the printed wiring board on the secondary side in conventional cases are eliminated, and the cost of materials and the number of operations can be reduced. |
