BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a power circuit structure, in particular to a power supply current circuit structure that can reduce the installation area of a printed circuit board and achieve the effects of providing a simple and easy manufacture, saving manpower, and assuring the safety of electronic components. 
         [0003]    2. Description of the Related Art 
         [0004]    As all present existing computers come with a power supply for converting 110VAC or 220VAC power inputted from an external cable into 12VDC or ±5VDC power required by hardware equipments including a main board, a hard disk, and an optical disk drive, etc. The power supply includes a printed circuit board provided for installing or inserting a plurality of electronic components directly. Particularly, a high-power electronic component (such as a capacitor) has to take the requirements of passing a large current and heat dissipation into consideration, and thus the area of the printed circuit board cannot be reduced effectively, and it constitutes a limitation of it&#39;s application to products with a light, thin, short and compact design. To overcome this problem, the existing technologies still erect some of the electronic components on the printed circuit board as shown in  FIG. 1 . The conventional power supply current circuit structure includes a printed circuit board  90 , and the printed circuit board  90  includes electronic components (not shown in the figure) and a sub-circuit board  91 , and the sub-circuit board  91  includes local electronic components  92  installed thereon, and if the local electronic components  92  are electronic components requiring the supply of a large current, the sub-circuit board  91  must be thickened and broadened by repeated soldering processes to form a large current path  93 , such that the large current path  93  provides the large current requirement to the local electronic components  92 . 
         [0005]    Although the aforementioned existing power supply current circuit structure can maximize the utility of space or reduce the area and space of the power supply, yet the large current path  93  formed by the repeated soldering method (to thicken and broaden the sub-circuit board) may burn the electronic components installed on the sub-circuit board  91  due to overheat or cause a low performance, and the repeated soldering process also has the shortcomings of increasing the manpower, giving an ugly appearance of the product to damage the product image, and failing to comply with the environmental protection requirement of minimizing the soldering operation. Therefore, it is an important subject for designers and manufacturers of the related industry to improve the existing power supply current circuit structure and overcome the shortcomings of the prior art. 
         [0006]    In view of the shortcomings of the conventional printed circuit board, the inventor of the present invention conducted extensive researches and experiments, and finally developed a power supply current circuit structure that can reduce the installation area of a printed circuit board and achieve the effects of providing a simple and easy manufacture, saving manpower, and assuring the safety of electronic components. 
       SUMMARY OF THE INVENTION  
       [0007]    Therefore, it is a primary objective of the present invention to provide a power supply current circuit structure for facilitating the manufacture of a printed circuit board with a large current path in a more convenient and economic way and preventing related electronic components from being damaged to assure the quality, stability and safety of the electronic components, and improve the product competitiveness. 
         [0008]    To achieve the foregoing objective, the present invention provides a power supply current circuit structure comprising: a conducting plate device, being made of an electrically conducting material and including a plurality of conducting plates, a plurality of insert holes disposed on the conducting plate, and each insert hole having a polarity opposite to the polarity of an adjacent conducting plate; an insulating layer, fixed onto the conducting plate device, and made of a non-conductive material; an electronic component module, installed onto the insulating layer, and including a plurality of electronic components, and the electronic components including two insert pins passed through the insulating layer and connected to the insert hole of the adjacent conducting plate to form a current path. 
         [0009]    The insulating layer can be a non-conducting plate, and includes a plurality of insert holes corresponding to the insert holes of the conducting plate respectively, and the insert holes of the insulating layer are provided for passing the insert pins of electronic components and connecting the insert pins to the insert holes of the adjacent conducting plate to form a current path. 
         [0010]    The insulating layer can be formed by coating a non-conductive thermal insulating sol-gel coating onto the conducting plate, such that when the electronic components are inserted and installed to the conducting plate, the insulating layer is provided for achieving the insulation effect between the adjacent conducting plates.
