[0020] The present invention may best be understood through the following description with reference to the accompanying drawings, in which:

[0021] FIG. 1 is a functional block diagram illustrating a preferred embodiment of a power supply system according to the present invention;

[0022] FIGS. 2A-2B are a decomposed diagram and an assembly diagram illustrating the first connector in FIG. 1;

[0023] FIGS. 3A-3B are a decomposed diagram and an assembly diagram illustrating the second connector in FIG. 1; and

[0024] FIG. 4 is an assembly diagram illustrating the combination of the first connector and the second connector according to the present invention.

[0025] The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.

[0026] FIG. 1 is a functional block diagram illustrating a preferred embodiment of a power supply system according to the present invention. The power supply system is applied in a power supply system with an output power larger than 100 watt. As shown in FIG. 1, the power supply system includes an electronic equipment 1, a power supply apparatus 2, a first connector 3 and a second connector 4. The power supply apparatus 2, such as an adapter, is used for transforming an input alternating current into a direct current transmitted to the electronic equipment 1, such as a desktop computer, by the first and second connectors 3, 4. The operation principle of power supply apparatus is well known to those skilled in the art, so that detailed description is omitted herein.

[0027] FIGS. 2A-2B are a decomposed diagram and an assembly diagram illustrating the first connector in FIG. 1. The first connector 3 has a first body 30 made of plastic and formed by molding. The first body 30 is covered by a first metal cover 31 for sheltering from the interference of external electromagnetic wave. A plurality of terminal bases 32 is disposed in the interior of the first body 30 and conductive pins 321 are inserted into partial terminal bases 32. The conductive pins 321 is connected to the corresponding electronic wires 13 as shown in FIG. 4 for transmitting current to the electronic equipment 1.

[0028] FIGS. 3A-3B are a decomposed diagram and an assembly diagram illustrating the second connector in FIG. 1. The second connector 4 has a second body 40 made of plastic and formed by molding. The second body is covered by a second metal cover 41 for also sheltering from the interference of external electromagnetic wave. A plurality of slots 42 is disposed inside of the second body 40 and corresponding to the partial conductive pins 321. Conductive terminals 421 are inserted into the slots 42 and connected to the corresponding electronic wires 24 as shown in FIG. 4 for receiving current from the power supply apparatus 1.

[0029] In addition, an elastic buckling element 33 is disposed on the first body 30 as shown in FIGS. 2A and 2B and integrally formed with the first body 30. Furthermore, a protruding element 43 corresponding to the elastic buckling element 33 is disposed on the second body 40 as shown in FIGS. 3A and 3B and integrally formed with the second body 40. The elastic buckling element 33 includes a support portion 331, a suppress portion 332 and a buckling portion 333. When the suppress portion 332 is pressed down, the buckling portion 333 will upwardly move. When the force is released, the buckling portion 33 will be back to the original position. Thus, the elastic buckling element 33 can buckle with the protruding element 43 each other.

[0030] FIG. 4 is an assembly diagram illustrating the combination of the first connector and the second connector according to the present invention. As shown in FIG. 4, when the terminal bases are combined with the slots 42 and the conductive pins 321 are contacted with the conductive terminals 421, the first connector 3 and the second connector 4 are combined together by buckling the elastic buckling element 33 with the protruding element 43.

[0031] For the practical requirement, the numbers of the terminal bases and the slots can be increased or reduced. At the same time, the numbers of the conductive pins and the conductive terminals also have to cooperatively increase for increasing output.

[0032] In sum, the present invention provides that the power supply apparatus is disposed out of the case of the electronic equipment for increasing the internal space of the electronic equipment for the circuit outlet, increasing the efficiency of the electronic equipment, and enhancing heat-dissipating effect wherein the electronic equipment includes no power supply apparatus therein. Owing to save the internal space of the electronic equipment such as desktop computer, the desktop computer is miniaturized and has high performance because the motherboard can expand the circuit layout or the case size of the desktop computer can be reduced. Furthermore, because the power supply apparatus is one of heat-generating unit in the desktop computer, the present invention can reduce the heat-generating unit in the case for efficiently increasing the efficiency and stability of the desktop computer. In addition, the connecter according to the present invention can increase the transmitted current, efficiently prevent from the interference of the electromagnetic wave. Moreover, the first metal cover of the first connector can guide the static electricity transmitted to the second metal cover of the second connector and further transmitted to the case to grounding, so the present invention provides the function of the electrical static defense (ESD).

[0033] While the invention has been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention need not to be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
