2. Description of the Related Art
As science and technology advances, electronic technology is well developed accordingly, and electronic products become an indispensable part of our life. Each electronic product tends to be short, small, light and thin and comes with diversified functions, and the electronic product with the short, small, light and thin design must have densely installed electronic components to reduce their occupying space.

Since the power supply board 200 is formed by stacking two circuit boards in parallel with each other, the volume is increased, and the distance between the conducting plates 102 of the electric connector 100 must be increased accordingly, and the power supply board 200 is installed on both lateral sides of the electric connector 100. Such arrangement not only causes a poor contact easily, but also results in a tremendous difficulty of reducing the volume of the whole device.
It is a primary objective of the present invention to overcome the foregoing shortcomings of the prior art by providing a micro power supply device inserted into slots of a circuit board, and the circuit board is fixed into an electronic system, and the device comprises a power supply board and an electric connector; wherein the power supply board includes a power-in connector, a power-out connector, an electronic part and a conductive contact point (commonly known as a goldfinger), and the power-in connector is connected with a DC power of an external port, and the power-out connector is connected with other electronic equipments for supplying the required DC power, and the electronic part is provided operating the circuit of the power supply board, and an end of the conductive contact point is connected with the electronic part, and another end of the conductive contact point is protruded from a surface of the power supply board; wherein a plurality of neatly and oppositely arranged protruding conducting plates are disposed on a side of the electric connector, and the positions and quantity of the conducting plates correspond to those of the conductive contact points. The conducting plates are installed at positions proximate to the middle, and the distance between the conducting plates is provided for precisely inserting conductive contact points, wherein the conducting plates are in a close contact with the conductive contact points, and the power supply board is integrated with the electric connector. Another side of the electric connector has a plurality of pins, and each pin is provided for sheathing onto another end of the conducting plate, and the pins can be inserted into the slots of the circuit board to constitute an electric connection and supply the required power to the circuit board. Compared with the prior art, the thickness of the power supply board can be reduced, and the invention not only centralizes the conducting plates from both lateral sides towards the middle to reduce the volume of the whole electric connector and results in a smaller volume of the whole device, but also reduces or eliminates the occurrence of a poor contact.
Another objective of the present invention is to provide a micro power supply device having an inputted DC power of 6V ˜48V.
A further objective of the present invention is to provide a micro power supply device having an outputted DC power of 3.3, 5, +12V or 5VSB (5V power standby).
Another further objective of the present invention is to provide a micro power supply device, and the exterior of the power supply board is encapsulated with a plastic substance (such as silicone and plastic) and integrated with the electric connector to provide a simple and neat appearance of the power supply device.
To make it easier for the examiner to understand the object, shape, structure, device, characteristics and functions of this invention, the specification accompanied by the drawings is described as follows.
The present invention relates to a micro power supply device inserted into slots 31 of a circuit board 30, and the circuit board 30 is fixed into an electronic system. Referring to
Further, another end of the conducting plate 12 is protruded from another side of the electric connector 10, and the conducting plate 12 is installed at a position proximate to the middle of the electric connector 10, and a predetermined gap is disposed between the opposite and protruding conducting plates 12. A power supply board 20 is inserted into the gap, and the power supply board 20 of this preferred embodiment is a circuit board, and the power supply board 20 has a conductive contact point 21 (commonly known as a goldfinger) on a surface in contact with an end of the conducting plate 12. The quantity and positions of the conductive contact points 21 correspond to those of the conducting plates 12, such that when the power supply board 20 is inserted into the gap, the conducting plates 12 can be fixed onto the electric connector 10 by clamping or soldering, and the conducting plates 12 and the conductive contact points 21 are contacted to form an electrically conducting circuit.
The power supply board 20 further installs a plurality of designed electronic parts 22, and the power supply board 20 has a power-in connector 23 and a power-out connector 24, wherein the power-in connector 23 can be connected with a DC power of an external port (not shown in the figure), and the external DC power of this embodiment is 6˜48V, and the power supply board 20 supplies the required power of the circuit board 30, and the power-out connectors 24 are connected with other electronic equipments (not shown in the figure) for supplying the required DC power, and the DC output power terminal can provide a PSON control signal (Power Supply On control signal), a PWRGOOD signal (Power Good control signal) and a DC power of 3.3, 5, +12V or 5VSB (5V Power Standby).
