The snap-fit shaft 41 is provided with a tensioning portion 411. The first snap-fit ring 42 and the second snap-fit ring 43 are sequentially arranged on the tensioning portion 411. A first snap-fit groove 44 is provided between the first snap-fit ring 42 and the snap-fit shaft 41. The power board 2 is provided with a first snap-fit fixing groove 21. The first snap-fit groove 44 is used to cooperate with the first snap-fit fixing groove 21 to fix the power board 2. The top cover 3 is provided with a connecting post 31, which is provided with a second snap-fit fixing groove 32. The second snap-fit fixing groove 32 is used to cooperate with the second snap-fit ring 43 to snap-fit and connect the top cover 3 to the bottom shell 1. In this embodiment, the fastening assembly 4 achieves a stable connection between the power board 2, the bottom shell 1, and the top cover 3, which not only improves the overall structural strength and stability of the product, but also significantly optimizes the assembly process and reduces production costs.
[0028] This embodiment provides a reliable fixing mechanism between the power board 2 and the bottom shell 1 through the opening and closing part 411 provided on the fastening shaft 41, and the first fastening ring 42 and the second fastening ring 43 arranged thereon. The first fastening groove 44 between the first fastening ring 42 and the fastening shaft 41 precisely matches the first fastening fixing groove 21 on the power board 2, ensuring that the power board 2 is firmly installed in the bottom shell 1, effectively preventing loosening or falling off due to vibration or external force, thereby extending the service life of the product.
[0029] The snap-fit assembly in this embodiment greatly simplifies the assembly steps and reduces the investment of tools and time required for assembly. Users or manufacturers only need to align the power board 2 with the snap-fit component 4 of the bottom shell 1, and the initial fixation can be completed by the natural engagement of the snap-fit groove and the fixing groove. Subsequently, the upper cover 3 and the bottom shell 1 are tightly snapped together by the cooperation of the connecting post 31 on the upper cover 3 and the second snap-fit fixing groove 32 on it with the second snap-fit groove. The whole process does not require the use of additional fasteners, which is both efficient and convenient.
[0030] This embodiment, through its snap-fit assembly, not only ensures structural robustness but also, by eliminating exposed screws and fasteners, results in a cleaner, more streamlined product appearance, enhancing overall aesthetics. Furthermore, this design reduces potential safety hazards caused by loose screws during use, thus improving user safety.
[0031] The outer periphery of the bottom shell 1 is provided with an assembly step 11, and the outer periphery of the top cover 3 is provided with a mating step 33, which is used to mate with the assembly step 11. Specifically, the bottom shell 1 is provided with a support ring 12, which is used to support one side of the power board 2. In this embodiment, the assembly step 11 on the outer periphery of the bottom shell 1 not only enhances the structural stability of the bottom shell 1, but also provides a precise positioning reference for the subsequent assembly process. At the same time, the outer periphery of the top cover 3 is provided with a matching mating step 33. The interaction of this pair of steps ensures that the bottom shell 1 and the top cover 3 can achieve a tight and stable fastening connection. The support ring 12 provided inside the bottom shell 1 plays a crucial role in the assembly process of the power board 2. The support ring 12 provides solid support for one side of the power board 2, effectively preventing deformation and displacement of the power board 2 during assembly or use, thereby ensuring precise docking and stable operation between the power board 2 and other components inside the socket.

Specifically, the opening and closing portion 411 is provided with an opening and closing groove 413, which is cross-shaped and extends towards the fastening shaft 41. One end of the opening and closing groove 413 passes through the abutment surface 412 and extends to the fastening shaft 41. In this embodiment, the abutment surface 412 specially provided on the side of the fastening shaft 41 facing the first fastening ring 42 maintains the same height as the support ring 12. This design ensures accurate positioning and seamless connection of each component during assembly. The presence of the abutment surface 412 not only provides a stable support point for the fastening ring but also effectively reduces assembly errors and improves the overall structural accuracy. At the same time, the cleverly designed cross-shaped opening and closing groove 413 of the opening and closing portion 411 further enhances the flexibility and reliability of the structure. The design of the clamping groove 413 allows the fastening shaft 41 to be smoothly inserted and fixed, while one end of the groove passes through the abutment surface 412 and extends to the fastening shaft 41. This layout optimizes the assembly path, simplifies the operation steps, and makes the assembly process of the socket power board 2 smoother and more efficient.
[0033] The power board 2 includes a board body 22 and a plug-in module 23.

[0034] The plug-in module 23 is provided with a first plug hole 231, and the upper cover 3 is provided with a second plug hole 36, with the first plug hole 231 and the second plug hole 36 facing each other. Specifically, the connecting post 31 is provided with a through hole 311, one end of which is connected to the second fastening and fixing groove 32. In this embodiment, the relative arrangement of the first plug hole 231 and the second plug hole 36 ensures that the plug-in module 23 and the upper cover 3 can be precisely aligned during assembly, improving the stability of the overall structure and assembly efficiency. This design avoids assembly difficulties caused by plug hole misalignment and potential electrical connection problems. Secondly, the through hole 311 provided on the connecting post 31, with one end connected to the second fastening and fixing groove 32, not only enhances the connectivity and flexibility of the internal wiring of the socket power board 2, but also makes it easy to arrange and fix the wiring through the through hole 311 during assembly. This simplifies the assembly process.
