[0038] When it is required to mount the plug assembly 2 on the composite socket body 1, only one end of the key 32 is required to be pressed, the key 32 slides towards the inside of the socket housing 11 along the sliding groove 31, the return spring of the key 32 is compressed, then the fixing hook body 34 is inserted in alignment with the fixing hook insertion hole 35, and the key 32 is released. The key 32 moves and returns outwards under the elastic restoring force of the key return spring 33, so that the side edge of the fixing hook body 34 is inserted into the fixing hook insertion hole 35 and cannot be pulled out, which mounts the plug assembly 2 on the composite socket body 1. At this moment, the composite socket body 1 is in conductive connection with the plug assembly 2, the external power plug to be converted is correspondingly inserted into the composite socket body 1, and the plug assembly 2 is correspondingly inserted into the external socket, so that the conductive conversion of the power can be realized.
[0039] When the plug assembly 2 is required to be replaced, only one end of the key 32 is required to be pressed, the key 32 slides along the sliding groove 31 towards the inside of the socket housing 11, the key return spring 33 is compressed, then the fixing hook body 34 is pulled out from the fixing hook insertion hole 35, and then the key 32 is released. The key 32 moves and returns outwards under the elastic restoring force of the key return spring 33, waiting for the next installation and use of the plug assembly 2. The whole operation is simple and convenient. The plug assemblies 2 of different modes and the composite socket body 1 are removably and fixedly mounted.

[0041] When the key 32 is pressed, the fixing cylinder 341 and the fixing hook body 342 disposed on the key 32 move synchronously in a direction away from the fixing hook avoidance groove 351. After the fixing cylinder 341 and the fixing hook body 342 are inserted in alignment with the fixing hook insertion hole 35, the key 32 is released. The key 32 drives the fixing cylinder 341 and the fixing hook body 342 to move in the direction of the fixing hook avoidance groove 351 under the elastic restoring force of the key return spring 33, so that the fixing hook body 342 is inserted into the fixing hook avoidance groove 351, and cannot be separated without applying an external force, thereby achieving the mounting between the plug assembly 2 and the composite socket. When it is necessary to pull out the plug assembly 2, it is only necessary to press the key 32, and the fixing cylinder 341 and the fixing hook body 342 disposed on the key 32 move synchronously in a direction away from the fixing hook avoidance groove 351. The fixing hook body 342 is disengaged from the fixing hook avoidance groove 351, then the fixing cylinder 341 and the fixing hook body 342 are pulled out from the fixing hook insertion hole 35, and then the key 32 is released. The key 32 moves and returns outwards under the elastic restoring force of the key return spring 33, waiting for the next installation and use of the plug assembly 2. The whole operation is simple and convenient. The plug assembly 2 with different modes can be freely replaced and mounted on the composite socket body 1, so as to meet people's requirements for the conversion of pins of different modes and facilitate the use..

When the fixing hook body 34 is embedded into the fixing hook avoidance groove 351, the fixing hook inclined guide surface 3421 on the fixing hook body 342 first contacts the side edge of the fixing hook avoidance groove 351. Under the inclined guide action of the inclined guide surface 3421 of the fixing hook, the fixing hook body 342 is more easily and accurately inserted into the fixing hook avoidance groove 351, thereby improving the efficiency and accuracy of the fixing hook body 34 being inserted into the fixing hook avoidance groove 351 and facilitating the cooperation between the components.
[0044] With regard to the fixing method for the reset spring of the key 32, as shown in Figs. 5 and 6, as shown in Figs. 2, 7 and 16, a first spring fixing column 311 for one end of the key return spring 33 to be sheathed is formed at the lower part of the sliding groove 31, and a second spring fixing column 321 for the other end of the key return spring 33 to be sheathed is formed at the lower part of the key 32. One end of the key return spring 33 is sheathed on the first spring fixing column 311 and the other end is sheathed on the second spring fixing column 321, so as to realize the function of being pressed and deformed by the key 32 and provide the elastic restoring force for the reset of the key 32.
[0045] Preferably, as shown in Figs. 5 and 6, the number of the fixing hook bodies 34 is two groups, and the number of the fixing hook insertion holes 35 is also two corresponding groups, so that the two sides of the composite socket 1 can be stably fixed on the plug assembly 2, facilitating the cooperation between various components and ensuring conduction stability.
[0046] Preferably, as shown in Fig. 2, Fig. 9 to Fig. 15 and Fig. 17 to Fig. 26, in order to further facilitate the installation of the plug assembly 2 on the composite socket body 1 and prevent the plug assembly 2 from shifting, the socket housing 11 is formed with an installation limiting groove 112 into which the plug housing 21 is 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 so as to further improve the safety of the present power converter.
[0047] In order to adapt to different external socket situations, the plug assembly 2 can be set as an overall circular structure, the installation limiting groove 112 corresponds to a circular shape, the plug assembly 2 can also be an overall square structure, the installation limiting groove 112 corresponds to a square shape, and the plug assembly 2 can also be a back convex structure so as to prevent an external socket from being too narrow and difficult to insert. The installation limiting groove 112 can be correspondingly set to a depth, and the overall structure of the plug assembly 2 can be set according to actual situations, which are not particularly limited in this embodiment.
[0048] With regard to the specific structural arrangement of the installation limiting groove 112, as shown in Figs. 2, 9-15 and 17-26, the installation limiting groove 112 may be in the shape of a groove which is integrally recessed on the composite socket body 1 and of which the edge is closed. The plug assembly 2 is correspondingly embedded in the installation limiting groove 112, or may be in the shape of a groove which is integrally recessed and of which one end is open. The plug assembly 2 correspondingly slides into the installation limiting groove 112 from the opening, or may have other shapes, which can be selected according to actual usage requirements.
[0049] As shown in Figs. 17 to 26, if the installation limiting groove 112 is in the shape of a groove groove which is integrally recessed and of which one end is open, a plug avoidance sliding groove 27 can be disposed between the plug housing 21 and the socket panel 22, the plug avoidance sliding groove 27 movably inserted into the socket live wire guide 131, the socket neutral wire guide 141 and the socket ground wire guide 151, respectively. While the plug assembly 2 is placed in the installation limiting groove 112, the socket live wire guide 131 correspondingly slides on the plug avoidance sliding groove 27 and is inserted into the plug live wire copper clip 231 at the tail end of the plug avoidance sliding groove 27. The socket neutral wire guide 141 correspondingly slides on the plug avoidance sliding groove 211 and is inserted into the plug neutral wire copper clip 241 at the tail end of the plug avoidance sliding groove 27. The socket ground wire guide 151 correspondingly slides on the plug avoidance sliding groove 27 and is inserted into the plug ground wire copper clip 251 at the tail end of the plug avoidance sliding groove 27 so as to complete the conduction conversion of the composite socket body 1 and the plug assembly 2.
