## Background
BACKGROUND OF THE INVENTION
(a) Field of the Invention

(b) Description of the Prior Art
Referring to FIGS. 1 and 2, which show a prior art power connector A, wherein a first conductive body A2 and a second conductive body A3 are disposed within a holding cavity A4 of an insulating body A1, thereby enabling the power connector A to combine the first conductive body A1 and the second conductive body A3 into an integrated body.

The covering case F comprises a holding space F2 that is used to hold the conductive terminal D. When the insulating body C including the conductive terminal D is contained within the holding space F2, then the power supply connector B can be soldered to a printed-circuit board using soldering portions F1 of the covering case F, the soldering portions D3 of the first conductive terminal D1, the soldering portions D7 of the second conductive terminal D5 and the soldering portions E2 of the signal terminal E, thereby achieving the objective of enabling a power connector A to achieve a stable connection and conducting of electric power.
Referring to FIGS. 5, 6 and 7, which show an embodiment of the present invention, wherein after the insulating body C and the covering case F are joined together, then the front insulating body C1 and the rear insulating body C4 are fixedly combined together to from an integrated body by means of the joining holes C3 of the front insulating body C1 and the connecting portions C8 of the rear insulating body C4. Moreover, when the front insulating body C1 is combined with the covering case F, the front insulating body C1 is secured within the covering case F by means of check portions C9 on side surfaces of the front insulating body C1, which prevent the front insulating body C1 from sliding out.
Furthermore, when the rear insulating body C4 and the covering case F are joined together, guide portions C10 of the rear insulating body C4 and check portions C11 of the guide portions C10 are able to fixedly combine together the rear insulating body C4 and the covering case F to form an integrated body. When the rear insulating body C4 and the covering case F are joined together, the rear insulating body C4 is smoothly disposed within the covering case F by means of inclined surfaces C12 of the guide portions C10, and the check portions C11 of the guide portions C10 prevent the rear insulating body C4 from sliding out.

Furthermore, the signal terminal E comprises check portions E1 that are used for combining with the insulating body C4 by embedding therein, and the solderable and conductive soldering portions E2 and the contact portions E3.
The first conductive terminal D1 and the second conductive terminal D5 are annular flexible bodies. Moreover, annular surfaces of the annular flexible first conductive terminal D1 and the second conductive terminal D5 provide good flexible support. When the first conductive terminal D1 and the second conductive terminal D5 are embedded into and thereby combined with the front insulating body C1 and the rear insulating body C4 respectively, then the power supply connector B can be soldered to a printed-circuit board, thereby producing a good conductive contact between the first conductive terminal D1 and the second conductive terminal D5.
Referring to FIG. 8, when the power supply connector B makes contact with an electric plug G, then the first conductive terminal D1 makes contact with outer layer conductive portions G1, the second conductive terminal D5 makes contact with inner layer conductive portions G2 and a connecting portion G3 protruding from a center of the electric plug G is clamped within the signal terminal E, thereby embedding the power supply connector B within the electric plug G and achieving the objective of electric conductance and signal transmission.
After the contact portions D4 of the first conductive terminal D1 and the contact portions D8 of the second conductive terminal D5 joined within the insulating body C have made contact with the inner and outer layer conducting portions G1, G2 of the electric plug G, then an electrical contact is made between the power supply connector B and the electric plug G, and a good contact is achieved between the first conductive terminal D1 and the second conductive terminal D5 without causing deformation in the conductive terminal D.
