Further, as Figure 2A shown, the second insert piece 2221 is coupled to the first insert piece 2321, so that the live wire connection component and the neutral wire connection component are closely matched.

[0049] In this embodiment, two live wire jaws 231 are provided at one end of the live wire connecting piece 23, and two neutral wire jaws 221 are provided at one end of the neutral wire connecting piece 22. The live wire connecting piece 23 and the live wire jaws 231 are integrally formed, and the neutral wire connecting piece 22 and the neutral wire jaws 221 are integrally formed. In addition, in actual use, different numbers of live wire jaws 231 and neutral wire jaws 221 can be designed for the live wire connecting piece 23 and the neutral wire connecting piece 22 according to the size of the power conversion device.

[0051] In this embodiment, two grounding jaws 211 are provided at one end of the grounding connection piece 21, and the structure is similar to that of the live wire connecting piece 23 and the neutral wire connecting piece 22. The grounding connection piece 21 and the two grounding jaws 211 are integrally formed, reducing the magnitude of the grounding resistance and further providing safety and reliability for subsequent grounding protection. In actual use, different numbers of grounding jaws 211 can be designed for the grounding connection piece 21 according to the size of the power conversion device.

[0052] As Figures 2A - 3B shown, the grounding ring receiving member 212 includes: a receiving plate 2121 on which the grounding ring 24 is disposed, a pair of buckles 2123 respectively disposed on both sides of the receiving plate 2121, and a first receiving opening groove 2124 disposed on the receiving plate 2121.

[0053] Among them, the pair of buckles 2123 are used to fix the grounding ring 24 to the receiving plate 2121; the first receiving opening groove 2124 is used to cooperate with the grounding ring 24 and the grounding screw 6.

[0054] In addition, as can be seen in the figure, an opening 2125 is provided in the first receiving opening groove 2124 (as Figure 2B shown).

[0055] The grounding ring 24 includes: a grounding ring body 241 and a second receiving opening groove 242. Specifically, the second receiving opening groove 242 is provided on the grounding ring body 241 and is used to cooperate with the first receiving opening groove 2124 and the grounding screw 6.

[0056] In addition, in this embodiment, an installation hole 243 is provided in the second receiving opening groove 242 (as Figure 3A shown), and the installation hole 243 cooperates with the opening 2125 in the first receiving opening groove 2124, so that the grounding screw 6 locks the grounding connection assembly to the two-pin power socket 7 through the installation hole 243, the opening 2125, and the grounding hole 71.

[0057] The grounding ring 24 is adjustably arranged on the grounding connection piece 21 to adapt to the grounding size of existing sockets on the market and improve the versatility of the power conversion device.

[0058] In this embodiment, based on the position of the grounding hole 71 of the two-pin power socket 7, the position of the grounding ring 24 on the grounding ring receiving member 212 is adjusted, so that the grounding screw 6 locks the grounding connection piece 21 and the grounding ring 24 to the grounding hole 71.

[0059] As Figure 3A shown, when the grounding ring 24 is arranged in the grounding ring receiving member 212, the grounding ring body 241 is fixed at the first position of the receiving plate 212 through a pair of buckles 2123, and the first receiving opening groove 2124 and the second receiving opening groove 242 cooperate with each other, so that the grounding screw 6 passes through the first receiving opening groove 2124 and the second receiving opening groove 242 (through the installation hole 243 and the opening 2125) for locking.

[0060] As Figure 3B shown, when the grounding ring 24 is arranged in the grounding ring receiving member 212, the grounding ring body 241 is fixed at the second position of the receiving plate 212, which is different from the first position, through a pair of buckles 2123, and the first receiving opening groove 2124 and the second receiving opening groove 242 cooperate with each other, so that the grounding screw 6 passes through the first receiving opening groove 2124 and the second receiving opening groove 242 for locking.

[0061] Specifically, as Figure 4B shown, according to the position of the grounding hole 71 of the two-pin power socket 7, the position of the grounding ring 24 on the grounding ring receiving member 212 is adjusted, thereby changing the matching position of the installation hole 243 and the opening 2125. Thus, the grounding screw 6 fixes the grounding connection assembly to the two-pin power socket 7 through the installation hole 243, the opening 2125, and the grounding hole 71 to achieve a reliable grounding effect.

[0062] The housing 5 includes: at least one live pin opening 53, at least one neutral pin opening 52, at least one grounding pin opening 51, and at least one USB socket 54. As Figure 5A and Figure 5BAs shown, in this embodiment, the housing 5 includes: two live pin openings 53, two neutral pin openings 52, two ground pin openings 51, and at least one USB socket 54. Among them, the live pin openings 53 are provided on the first surface 510 of the housing 5 and correspond to the positions of the corresponding live wire jaws 231; the neutral pin openings 52 are provided on the first surface 510 and correspond to the positions of the corresponding neutral wire jaws 221; the ground pin openings 51 are provided on the first surface 510 and correspond to the positions of the corresponding ground wire jaws 211; the USB socket 54 is provided on the second surface 520 of the housing 5 that is different from the first surface 510.

[0063] In this embodiment, according to the size of the power conversion device, the number of the live pin openings 53, neutral pin openings 52, ground pin openings 51, and USB sockets 54 in the housing 5 is designed so that the number of these openings corresponds one-to-one with the number of the corresponding jaws provided inside.

[0064] The USB socket 54 is provided on the second surface 520 of the housing 5 that is different from the first surface 510, so that the power conversion device can be flexibly applied, and the problem that the USB socket 54 is blocked due to the too large size of the socket of a certain electrical device will not occur, improving the user's satisfaction.

[0065] In addition, as Figure 5B shown, the power conversion device further includes: a ground test piece 55 is provided inside the housing 5 and is coupled to the circuit board 4 to test the grounding condition of the power conversion device.

[0066] Before using the power conversion device, the user first operates the ground test piece 55 to test whether the power conversion device is well grounded.

[0067] The power conversion device disclosed by the present invention can solve the problem that the traditional two-pin socket does not have a grounding function, and provides the functions of USB access and grounding detection, greatly meeting the user's needs for electrical safety and convenient use.

[0068] Therefore, although the present invention is described with reference to specific examples, and these specific examples are only illustrative and not restrictive of the present invention, it is obvious to those of ordinary skill in the art that changes, additions, or deletions can be made to the disclosed embodiments without departing from the spirit and protection scope of the present invention.
