Abstract: A micro power supply device is inserted into slots of a circuit board, and the circuit board is fixed into an electronic system. The device includes an electric connector and a plurality of neatly and oppositely arranged pins on a side of the electric connector, and the pins are sheathed with conducting plates, and the conducting plates are electrically connected with the slots. Another end of the conducting plates is protruded from another side of the electric connector, and a power supply board is inserted between the protruded conducting plates. The power supply board is connected with the power of an external port and other electronic equipments. The thickness of the power supply board is reduced, such that the conducting plates are centralized from both lateral side to the middle to reduce the volume of the whole electric connector, so as to reduce the volume of the whole device.

Abstract: The present invention discloses a power supply apparatus which is an apparatus installed in an electronic system, and the apparatus includes a DC power input transformer connected with a DC voltage adapter through an electric extension cord, such that DC power of different voltage values is rectified into a single voltage value through the DC power input transformer and transmitted to the DC voltage adapter through an electric extension cord, and divided into different voltage outputs by the adapter for supplying different voltages to electronic equipments. The invention not only installs the transformer and the adapter at appropriate spaces depending on the spaces of the electronic system, but also supplies DC power with different voltages to different electronic equipments.
