[0055] Sockets are prone to safety accidents when liquid gets into them. To prevent this, existing sockets use flexible waterproof components to seal the socket holes. However, with repeated plugging and unplugging, these waterproof components can break, reducing their waterproof performance.
[0056] To address the aforementioned issues, this patent provides a safety socket designed to prevent a reduction in the socket's waterproof performance due to wear and tear on waterproof components.
[0057] For ease of understanding, the specific implementation methods of the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0058] Please see Figure 1 , Figure 2 , Figure 8 , Figure 13 and Figure 22The safety socket includes a front shell 100, a bottom shell 200, and a flexible waterproof pad 300. The front shell 100 has a socket 110, and the flexible waterproof pad 300 is fixed to the front shell 100. The flexible waterproof pad 300 has a first through hole 310 for inserting a plug pin. A protective door 400 is located below the flexible waterproof pad 300. The protective door 400 has a flat surface on its side that adheres to the flexible waterproof pad 300. The flat surface abuts against the flexible waterproof pad 300, and the protective door 400 closes the first through hole 310 when the plug pin is not inserted. When the plug pin is inserted or removed, it is the protective door 400 that comes into contact with the plug pin. The protective door 400 is made of rigid material and is not easily worn. Even if wear occurs at the point of contact with the plug pin, it will not affect the sealing effect of the protective door 400 on the first through hole 310. This prevents a decrease in the waterproof performance of the socket due to wear on the waterproof components. Furthermore, since the elastic waterproof pad 300 is flexible, when the protective door 400 closes the first through hole 310 of the elastic waterproof pad 300, water cannot or is difficult to pass between the elastic waterproof pad 300 and the protective door 400, preventing water from entering the socket. In this embodiment, the elastic waterproof pad 300 can be fixed to the faceplate 100 by being attached to the faceplate 100, or by being fixed after injection molding as described later. It should be noted that the elastic waterproof pad can be non-sheet-shaped; the elastic waterproof pad 300, such as... Figure 25 In this implementation, the flat surface of the protective door 400 abuts against the lower end of the elastic waterproof pad 300 (e.g., Figure 25 The middle plane abuts against the rubber ring below the elastic waterproof pad 300.
[0059] It should be noted that there are multiple ways to fix the elastic waterproof gasket 300; this embodiment provides the following implementation method. Please refer to [link / reference]. Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 18 and Figure 19 The inner surface of the faceplate 100 is provided with a first protrusion 120; the elastic waterproof pad 300 is provided with a fixing hole 320, and the first protrusion 120 is embedded in the fixing hole 320. This implementation method can prevent the elastic waterproof pad 300 from shifting and achieve a fixing effect.
[0060] Based on the above implementation, in order to prevent the elastic waterproof pad 300 from falling off, this embodiment provides the following implementation. The end of the first protrusion 120 is provided with a locking part for limiting the elastic waterproof pad 300 to prevent it from falling off. In this embodiment, the shape of the locking part is not limited; it can be a hook-shaped locking part (hooking the elastic waterproof pad 300) or a sheet-shaped locking part (the sheet-shaped locking part is located below the elastic waterproof pad 300, and the sheet-shaped locking part cannot pass through the fixing hole 320).
[0061] It should be noted that, in order to prevent the elastic waterproof pad 300 from shifting, this embodiment provides the following implementation method. Please refer to [link / reference]. Figure 6 and Figure 7 The inner side of the faceplate 100 is provided with a first groove 130, and the elastic waterproof pad 300 is disposed in the first groove 130. The elastic waterproof pad 300 is disposed in the first groove 130, thus confining it within the groove and preventing it from shifting. During production, the user can injection mold the elastic waterproof pad 300 into the first groove 130. Furthermore, after injection molding, the elastic waterproof pad 300 does not require manual installation into the first groove 130, facilitating the user's production and assembly of the safety socket.
[0062] Based on the above implementation, in order to securely fix the elastic waterproof pad 300 to the first groove 130, this embodiment provides the following implementation. Please refer to... Figure 5 , Figure 6 and Figure 7 The first groove 130 includes an outer sub-groove 131 and an inner sub-groove 132, with an insertion hole 110 formed at the bottom of the inner sub-groove 132. The elastic waterproof pad 300 is provided with a second protrusion 330, which is embedded in the outer sub-groove 131. The outer sub-groove 131 extends outward from the edge of the inner sub-groove 132. The second protrusion 330 is located at the edge of the elastic waterproof pad 300. This implementation allows the elastic waterproof pad 300 to be securely fixed to the first groove 130.
[0063] Furthermore, to prevent the elastic waterproof pad 300 from converging towards the center when the plug pins are inserted into the first through hole 310, this embodiment provides the following implementation method. Please refer to... Figure 6 and Figure 7 The outer slot 131 and the inner slot 132 narrow at their junction. When the plug pins are inserted into the first through hole 310, the elastic waterproof pad 300 tends to converge towards the center. However, since the second protrusion 330 cannot pass through the junction of the outer slot 131 and the inner slot 132, the elastic waterproof pad 300 cannot converge towards the center and can maintain its original position.
[0064] It should be noted that, in addition to the aforementioned fixing methods, this embodiment also provides the following implementation methods for the elastic waterproof gasket 300. Please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 A socket unit 500 is provided below the elastic waterproof pad 300. The socket unit 500 includes a unit housing 510. The unit housing 510 is provided with a second through hole 511 for inserting a plug pin. An abutment portion 512 is formed on the unit housing 510, which abuts against the elastic waterproof pad 300. This implementation fixes the elastic waterproof pad 300 to the faceplate 100 by the abutment portion 512 against the elastic waterproof pad 300.
[0065] Based on the above implementation, the contact part 512 can be implemented in multiple ways. This embodiment provides the following two implementation methods.
[0066] Method 1:

The end of the partition 514 forms an abutment portion 512. This implementation enhances the fixing effect of the elastic waterproof pad 300.
[0069] Method 2:
[0070] Please see Figure 3 and Figure 4 The second through hole 511 includes a ground wire hole 511a, a ground wire enclosure 515 is formed at the ground wire hole 511a, and an abutment portion 512 is formed at the end of the ground wire enclosure 515.
[0071] It should be noted that, in order to further prevent water from entering the socket, this embodiment provides the following two implementation methods.

The second groove 140 is provided with a waterproof abutment 600. The waterproof abutment 600 abuts against the end face of the plug to prevent liquid from entering the socket 110 between the plug and the faceplate 100 when the plug pins are inserted into the socket. It should be noted that the second groove 140 is located around the socket 110, which can be located around a single socket 110, around a two-hole socket 110 (including a neutral wire socket and a live wire socket), around a three-hole socket 110 (including a neutral wire socket, a live wire socket, and a ground wire socket), or around both two-hole and three-hole socket 110 areas.
[0074] Based on the above implementation methods, the fixed elastic waterproof pad 300 can be implemented in various ways. This embodiment provides the following implementation methods. Please refer to... Figure 9 , Figure 10 , Figure 19 , Figure 23 , Figure 24 and Figure 25 The bottom of the second groove 140 is provided with a third through hole 141, and the third through hole 141 is provided with a first connecting post 700. The waterproof abutment 600 is connected to or integrally formed with the first connecting post 700 at one end, and the elastic waterproof pad 300 is connected to or integrally formed with the first connecting post 700 at the other end. This implementation method fixes the elastic waterproof pad 300 relative to the waterproof abutment 600. In addition, in the implementation method of providing the first groove 130 on the inner side of the shell 100, the elastic waterproof pad 300, the waterproof abutment 600 and the first connecting post 700 can be formed by injection molding, which is convenient for users to produce and assemble.
[0075] Method 2:
