Moreover, the plug assemblies 2 of different standards are not limited by the size of the composite socket. The plug assembly 2 can be set to multiple sets of different standards, such as any two or more combinations of British standard sockets, American standard sockets, Australian standard sockets, or Chinese standard sockets. The specific settings can be configured according to different standards based on actual conditions.

This achieves precise connection and conduction between the composite socket body 1 and the plug assembly 2, allowing external power plugs inserted into the composite socket body 1 to be switched by plugging into the plug assembly 2. The conduction is smooth, and plug assemblies 2 of different types can be freely replaced and installed on the composite socket, thereby meeting people's needs for conversion between different plug types and facilitating use.

[0053] Regarding the specific structural configuration of the socket live wire assembly 13, as follows: Figures 2 to 8 As shown, the socket live wire assembly 13 includes a socket live wire guide 131, one end of which can be electrically connected to the plug live wire assembly 23, and a live wire socket copper clip 132, one end of which matches the composite socket panel 12 and the other end of which is electrically connected to the socket live wire guide 131. The live wire component of the external power plug that needs to be converted passes through the composite socket panel 12 and is inserted into the live wire socket copper clip 132, thereby making a conductive connection with the live wire socket copper clip 132, and then electrically connecting to the socket live wire guide 131 through the live wire socket copper clip 132, completing the conversion and conduction between the live wire of the external power plug and the composite socket body 1.

[0054] Preferred, such as Figures 2 to 8As shown, a fuse assembly 16 is also provided between the socket live wire conductor 131 and the live wire socket copper clip 132. The fuse assembly provides overload protection for the circuit of the composite socket body 1, further improving the safety of this power converter. The fuse assembly 16 can be a fuse tube, a fuse wire, or other components that can protect the circuit. It can be selected according to the actual situation, so no specific limitation is made in this embodiment.

[0055] Regarding the specific structural configuration of the socket neutral wire assembly 14, as follows: Figures 2 to 8 As shown, the socket neutral wire assembly 14 includes a socket neutral wire guide 141, one end of which can be electrically connected to the plug neutral wire assembly 24, and a neutral wire socket copper clip 142, one end of which matches the composite socket panel 12 and the other end of which is electrically connected to the socket neutral wire guide 141. The neutral wire component of the external power plug that needs to be converted passes through the composite socket panel 12 and is inserted into the neutral wire socket copper clip 142, thereby making a conductive connection with the neutral wire socket copper clip 142, and through the neutral wire socket copper clip 142, it is electrically connected to the socket neutral wire guide 141, completing the conversion and conduction between the neutral wire of the external power plug and the neutral wire of the composite socket body 1.

[0056] Regarding the specific structural configuration of the socket grounding assembly 15, as follows: Figures 2 to 8 As shown, the socket grounding assembly 15 includes a socket grounding conductor 151, one end of which can be electrically connected to the plug grounding assembly 25, and a grounding socket copper clip 152, one end of which matches the composite socket panel 12 and the other end of which is electrically connected to the socket grounding conductor 151. The grounding component of the external power plug that needs to be converted passes through the composite socket panel 12 and is inserted into the grounding socket copper clip 152, thereby making a conductive connection with the grounding socket copper clip 152.

The specific structure of the protection door assembly 17 is a conventional technical means in the art, and can be referred to in the prior art such as patent number 202021218777.2, so it will not be described in detail in this embodiment.

[0058] Regarding the specific structural configuration of the plug live wire assembly 23, as follows: Figure 2 and Figures 7 to 8 As shown, the plug live wire assembly 23 includes a plug live wire copper clip 231 electrically connected to the socket live wire guide 131, and a plug live wire pin 232 with one end electrically connected to the plug live wire copper clip 231. The socket live wire guide 131 passes through the plug panel 22 and is inserted into the plug live wire copper clip 231, thus establishing a conductive connection with the plug live wire copper clip 231. The plug live wire pin 232 is electrically connected to the plug live wire of the composite socket body 1, thereby completing the conversion and conduction between the live wire of the composite socket body 1 and the live wire of the plug assembly 2. The plug live wire pin 232 is inserted into the live wire position of the external socket, thus enabling the conversion and conduction between the live wire of the external power plug (which needs to be converted) and the live wire of the external socket body 1 after insertion into the live wire component of the composite socket body 1. This meets the needs of people traveling and requiring conversion between different plug types.

The plug neutral wire copper clip 241 is electrically connected to the plug neutral wire pin 242, thereby completing the conversion and conduction between the neutral wire of the composite socket body 1 and the neutral wire of the plug assembly 2. The plug neutral wire pin 242 is placed in the neutral wire position of the external socket, thereby realizing that after the neutral wire of the external power plug that needs to be converted is inserted into the neutral wire component of the composite socket body 1, the neutral wire between the composite socket body 1 and the plug assembly 2 and the neutral wire of the external socket is converted and conducted, thereby meeting people's needs for conversion of different plug types when traveling.

[0060] Regarding the specific structural configuration of the plug grounding assembly 25, as follows: Figure 2 and Figures 7 to 8As shown, the plug grounding assembly 25 includes a plug grounding copper clip 251 electrically connected to the socket grounding conductor 151, and a plug grounding pin 252 with one end electrically connected to the plug grounding copper clip 251.

The plug grounding copper clip 251 is electrically connected to the plug grounding pin 252, thereby completing the conversion and conduction between the grounding of the composite socket body 1 and the grounding of the plug assembly 2. The plug grounding pin 252 is placed in the grounding position of the external socket, thereby realizing that after the grounding of the external power plug that needs to be converted is inserted into the grounding component of the composite socket body 1, the conversion and conduction between the grounding of the composite socket body 1 and the plug assembly 2 and the external socket is achieved, thus meeting people's needs for conversion of different plug types when traveling.

[0061] Preferred, such as Figure 7 As shown, a plug protection door assembly 26 is provided between the plug live wire assembly 23 and the plug neutral wire assembly 24, thereby effectively preventing the accidental insertion of other objects and improving the safety of this power converter. The specific structure of the plug protection door assembly 26 is a conventional technique in the art, and therefore is not specifically limited in this embodiment.

[0062] Preferred, such as Figures 1 to 26 As shown, there are four plug assemblies 2, namely British plug assembly 2, Australian plug assembly 2, American plug assembly 2 and European Union plug assembly 2. The difference between the different plug assemblies 2 is that the specifications of the plug live wire pin 232, plug neutral wire pin 242 and plug ground wire pin 252 are different. All other structures are the same. The structure of the plug live wire copper clip 231, plug neutral wire copper clip 241 and plug ground wire copper clip 251 can be adapted to different standards.

[0063] The positions of the socket live wire guide 131, socket neutral wire guide 141, and socket ground wire guide 151 can be set according to the actual situation, and the positions of the plug live wire copper clip 231, plug neutral wire copper clip 241, and plug ground wire copper clip 251 can be adjusted accordingly.

[0064] Regarding the fixing method of the composite socket body 1 and plug assembly 2, as follows: Figure 2 and Figure 7 as well as Figure 16As shown, this power converter also includes a fixing component 3, which includes at least one groove 31 disposed between the composite socket panel 12 and the socket housing 11, a button 32 slidably mounted on the groove 31 and having one end protruding outside the socket housing 11, a button return spring 33 disposed between the groove 31 and the button 32, at least one fixing hook body 34 formed on the button 32 and having one end protruding outside the socket housing 11, and at least one fixing hook insertion hole 35 recessed on the plug panel 22 and matching the fixing hook body 34.

[0065] When the plug assembly 2 needs to be installed on the composite socket body 1, simply press one end of the button 32. The button 32 slides along the slide groove 31 into the socket housing 11, compressing the button 32 reset spring. Then, align the fixing hook body 34 with the fixing hook insertion hole 35 and insert it. Release the button 32, and the button 32 moves outward and resets under the elastic restoring force of the button reset spring 33, thereby embedding the side of the fixing hook body 34 into the fixing hook insertion hole 35 and preventing it from being pulled out. This allows the plug assembly 2 to be installed on the composite socket body 1. At this time, the composite socket body 1 and the plug assembly 2 are electrically connected. The external power plug that needs to be converted is inserted into the composite socket body 1, and the plug assembly 2 is inserted into the external socket, thus realizing the power conversion.

[0066] When the plug assembly 2 needs to be replaced, simply press one end of the button 32. The button 32 slides along the slide groove 31 toward the inside of the socket housing 11, compressing the button reset spring 33. Then, pull the fixing hook body 34 out of the fixing hook insertion hole 35, and release the button 32. The button 32 moves outward and resets under the elastic restoring force of the button reset spring 33, ready for the next installation and use of the plug assembly 2. The entire operation is simple and convenient. Different types of plug assemblies 2 can be detachably and securely fixed to the composite socket body 1, ensuring smooth conduction. Different types of plug assemblies 2 can be freely replaced and installed on the composite socket body 1, thus meeting people's needs for converting between different plug types and facilitating user convenience.

[0067] The specific method for fixing the hook body 34 by embedding it into the hook insertion hole 35 is as follows: Figure 2 , Figures 5 to 7 as well as Figure 16 As shown, the fixing hook body 34 includes a fixing post 341 with one end formed on the button 32 and the other end protruding out of the socket housing 11, and a fixing hook body 342 formed on the outermost side of the fixing post 341. A fixing hook recess 351 is provided on the side of the fixing hook insertion hole 35 for the fixing hook body 342 to be inserted.

[0068] When button 32 is pressed, the fixed post 341 and fixed hook 342 on button 32 move synchronously away from the fixed hook relief groove 351. After the fixed post 341 and fixed hook 342 are inserted into the fixed hook insertion hole 35, button 32 is released. Under the elastic restoring force of button reset spring 33, button 32 drives the fixed post 341 and fixed hook 342 to move towards the fixed hook relief groove 351, so that the fixed hook 342 is inserted into the fixed hook relief groove 351 and cannot be dislodged without external force, thereby realizing the installation between the plug assembly 2 and the composite socket. When it is necessary to unplug the plug assembly 2, simply press the button 32. The fixing post 341 and fixing hook 342, which are set on the button 32, move synchronously away from the fixing hook relief groove 351. The fixing hook 342 disengages from the fixing hook relief groove 351. Then, the fixing post 341 and fixing hook 342 are pulled out of the fixing hook insertion hole 35. Then, release the button 32. The button 32 moves outward and resets under the elastic restoring force of the button reset spring 33, waiting for the next installation and use of the plug assembly 2. The whole operation is simple and convenient, and the fixing is firm. Different types of plug assemblies 2 can be freely replaced and installed on the composite socket body 1, thereby meeting people's needs for conversion of different plug types and facilitating use.

[0069] Preferred, such as Figure 2 As shown, a transverse movable groove 111 is formed on the socket housing 11 for the fixed column 341 to move laterally.

[0070] Preferred, such as Figure 2 , Figures 5 to 7 as well as Figure 16 As shown, in order to further improve the efficiency of the fixed hook body 34 in embedding into the fixed hook relief groove 351, the upper end of the fixed hook body 342 is formed with a fixed hook inclined guide surface 3421 extending inclinedly from the outer end of the fixed column 341 toward the fixed hook body 342. When the fixed hook body 34 is embedded into the fixed hook relief groove 351, the fixed hook inclined guide surface 3421 on the fixed hook body 342 first contacts the side of the fixed hook relief groove 351. Under the inclined guiding action of the fixed hook inclined guide surface 3421, the fixed hook body 342 is more easily and accurately embedded into the fixed hook relief groove 351, thereby improving the efficiency and accuracy of the fixed hook body 34 in embedding into the fixed hook relief groove 351 and facilitating the cooperation between the components.

[0071] Regarding the fixing method of the reset spring of the button 32, as follows: Figures 5 to 6 As shown, Figure 2 and Figure 7 as well as Figure 16As shown, a first spring fixing post 311 is formed at the lower part of the slide groove 31 for one end of the button reset spring 33 to be sleeved, and a second spring fixing post 321 is formed at the lower part of the button 32 for the other end of the button reset spring 33 to be sleeved. One end of the button reset spring 33 is sleeved on the first spring fixing post 311 and the other end is sleeved on the second spring fixing post 321, so that it can be squeezed and deformed by the button 32, thereby providing the elastic restoring force for the button 32 to reset.

[0072] Preferred, such as Figures 5 to 6 As shown, there are two sets of fixing hook bodies 34 and two sets of fixing hook insertion holes 35, so that both sides of the composite socket 1 can be firmly fixed on the plug assembly 2, which facilitates the cooperation between the components and ensures the stability of conduction.

[0073] Preferred, such as Figure 2 , Figures 9 to 15 as well as Figures 17 to 26 As shown, in order to further facilitate the installation of the plug assembly 2 on the composite socket body 1 and to prevent the plug assembly 2 from shifting, an installation limiting groove 112 is formed on the socket housing 11 for the plug housing 21 to be inserted. When the plug assembly 2 is installed on the composite socket body 1, it is only necessary to align the plug housing 21 with the installation limiting groove 112 and insert it, which further improves the safety of this power converter.

[0074] To adapt to different external socket conditions, the plug assembly 2 can be configured as a circular structure, with the mounting limiting groove 112 correspondingly circular. Alternatively, the plug assembly 2 can be configured as a square structure, with the mounting limiting groove 112 also correspondingly square. The plug assembly 2 can also have a raised back structure to prevent the external socket from being too narrow to insert. The depth of the mounting limiting groove 112 can be adjusted accordingly. The overall structure of the plug assembly 2 can be configured according to actual conditions, so no specific limitations are imposed in this embodiment.

[0075] Regarding the specific structural design of the mounting limiting groove 112, as follows: Figure 2 , Figures 9 to 15 as well as Figures 17 to 26 As shown, the mounting limiting groove 112 can be a groove that is recessed on the composite socket body 1 and closed at the edges, with the plug assembly 2 correspondingly embedded in the mounting limiting groove 112. Alternatively, it can be a groove that is recessed on the whole and open at one end, with the plug assembly 2 correspondingly sliding into the mounting limiting groove 112 from the opening. It can also be other shapes, which can be selected according to actual usage requirements.

[0076] like Figures 17 to 26As shown, if the mounting limiting groove 112 is a groove-shaped structure that is recessed overall and open at one end, then a plug clearance sliding groove 27 can be provided between the plug housing 21 and the socket panel 22, respectively corresponding to the movable insertion of the socket live wire guide 131, the socket neutral wire guide 141, and the socket ground wire guide 151. Simultaneously with the plug assembly 2 being placed into the mounting limiting groove 112, the socket live wire guide 131 slides on the plug clearance sliding groove 27 and inserts into the plug live wire copper clip 231 at the tail end of the plug clearance sliding groove 27; the socket neutral wire guide 141 slides on the plug clearance sliding groove 211 and inserts into the plug neutral wire copper clip 241 at the tail end of the plug clearance sliding groove 27; and the socket ground wire guide 151 slides on the plug clearance sliding groove 27 and inserts into the plug ground wire copper clip 251 at the tail end of the plug clearance sliding groove 27, thereby completing the conduction conversion between the composite socket body 1 and the plug assembly 2.

[0077] It should be noted that the multi-country power converter with replaceable plug assembly disclosed in this utility model is an improvement on the specific structure, but the specific control method is not an innovation of this utility model. The protective door assembly, fuse assembly, UK standard socket, US standard socket, Italian standard socket, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0078] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
