[0032] Sockets are common electrical appliances, but safety accidents of sockets are not uncommon. The sockets in the prior art can only be waterproof when the plug pins are inserted, and cannot be waterproof when the plug pins are not inserted.

[0033] To solve the above problems, the present patent provides a safety socket, aiming to improve the waterproof ability of the socket. For easy understanding, the following will describe the detailed implementation manners of the embodiments of the present application with reference to the drawings.

[0034] Please refer to Figure 1 - 4 Figure 1 - 4 , a safety socket, including a face shell 100, a bottom shell 200 and a waterproof member 300. A first housing 400 is arranged between the face shell 100 and the bottom shell 200; the first housing 400 is provided with a through hole 410 and a waterproof level 420; the orifice of the through hole 410 is located within the waterproof level 420, or the orifice of the through hole 410 coincides with the waterproof level 420; the waterproof member 300 is arranged at the waterproof level 420 and / or the through hole 410 to close the through hole 410; the waterproof member 300 includes an elastic opening and closing part 310, and the elastic opening and closing part 310 is in a closed state when the plug pins are not inserted, and the elastic opening and closing part 310 is opened by the plug pins and elastically abuts against the side surface of the plug pins when the plug pins are inserted.

[0035] In this embodiment, conductive liquids such as water often enter from the face shell 100. Therefore, the first housing 400 located between the face shell 100 and the bottom shell 200 can play a waterproof role. The first housing 400 is provided with a through hole 410 for the plug pins to insert. This through hole 410 is a place where water may enter. Therefore, closing it when the plug pins are not inserted can achieve a waterproof effect. The first housing 400 is provided with a waterproof level 420, and the orifice of the through hole 410 is located within the waterproof level 420, or the orifice of the through hole 410 coincides with the waterproof level 420. When the waterproof level 420 is closed, the through hole 410 is closed. Obviously, when both the waterproof level 420 and the through hole 410 are closed, it will also achieve a waterproof effect, and the waterproof effect is better. The waterproof member 300 is a component for closing the through hole 410. It can be arranged at the waterproof level 420, or in the through hole 410, or both at the waterproof level 420 and in the through hole 410. The waterproof member 300 includes an elastic opening and closing part 310, which is in a closed state when the plug pins are not inserted. At this time, water cannot pass through the waterproof member 300. The elastic opening and closing part 310 is opened by the plug pins and elastically abuts against the side surface of the plug pins when the plug pins are inserted, so that the plug pins can pass through the waterproof member 300 and enter the socket interior. At the same time, due to the elastic abutment against the side surface of the plug pins, the plug pins are closely attached to the waterproof member 300, preventing water from passing between the waterproof member 300 and the plug pins. In this way, the socket can be waterproof both when the plug pins are inserted and when the plug pins are not inserted, improving the waterproof ability of the socket.

[0036] It should be noted that there are various implementation manners for the waterproof level 420. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, the present application provides a preferred implementation manner.

[0037] Please refer to Figure 4 Figure 4 , a groove 430 is formed on the first housing 400, and at least part of the groove 430 forms the waterproof level 420.

[0038] In this embodiment, the groove 430 on the first housing 400 at least partially forms a waterproof level 420, which means that either a part of the groove 430 forms the waterproof level 420 or the entire groove 430 forms the waterproof level 420. The implementation manner in which the groove 430 forms the waterproof level 420 makes it difficult for the waterproof member 300 to fall off or become loose from the first housing 400, avoiding the problem that the through hole 410 cannot be closed due to the detachment or loosening of the waterproof member 300.

[0039] It should be noted that, based on the technical solution in which the groove 430 at least partially forms the waterproof level 420, further, there is a technical problem of how to further enhance the waterproof effect of the waterproof member 300. To solve the above technical problem, the present application provides a preferred implementation manner.

[0040] Optionally, the waterproof member 300 includes a peripheral edge (not shown in the figure), the peripheral edge is located at the edge of the upper surface of the waterproof member 300, and the peripheral edge abuts against the side wall of the groove 430.

[0041] In this embodiment, when water enters from the front housing 100 and flows into the groove 430 along the notch, since the peripheral edge of the waterproof member 300 abuts against the side wall of the groove 430, the water cannot pass through between the peripheral edge and the side wall, or even if it passes through between the peripheral edge and the side wall, it is difficult for the water to pass through the gap between the peripheral edge and the side wall because the abutting manner makes the gap between the peripheral edge and the side wall narrow. In this embodiment, the height of the peripheral edge is not limited. Preferably, the upper end of the peripheral edge is not lower than the notch. In such an implementation manner, even if water enters the gap between the peripheral edge and the side wall, the difficulty of the water passing through the gap will be further increased because the length of the gap passed through is relatively long.

[0042] It should be noted that, based on the technical solution in which the groove 430 at least partially forms the waterproof level 420, further, there is a technical problem of how to minimize the water in the groove 430 when the waterproof member 300 is disposed in the groove 430 to enhance the waterproof effect. To solve the above problem, the present application provides a preferred implementation manner.

[0043] Please refer to Figure 5 - 6 , the upper surface of the waterproof member 300 is not lower than the notch of the groove 430.

[0044] In this embodiment, since the upper surface of the waterproof member 300 is not lower than the notch of the groove 430, there will be no drop in the groove 430 between the upper surface of the waterproof member 300 and the notch of the groove 430, that is, there will be no space for retaining water in the groove 430 due to the drop, so that the water does not remain in the groove 430, enhancing the waterproof effect.

[0045] It should be noted that the groove 430 has multiple implementation manners. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, the present application provides a preferred implementation manner.

[0046] Please refer to Figure 4 , the first housing 400 is provided with a cofferdam 440; the groove 430 is located at the bottom of the cofferdam 440, or at least part of the cofferdam 440 forms the groove 430.

[0047] In this embodiment, the groove 430 can be provided at the bottom of the cofferdam 440, or at least part of the cofferdam 440 forms the groove 430. That at least part of the cofferdam 440 forms the groove 430 means that either all the space inside the cofferdam 440 forms the groove 430 or part of the space inside the cofferdam 440 forms the groove 430. The implementation manner in which the cofferdam 440 forms the groove 430 has a better waterproof effect compared with the implementation manner of directly forming the groove 430 by recessing on the first housing 400 without the cofferdam 440, because the protruding cofferdam 440 can play a role similar to that of an isolation cavity. In addition, since the cofferdam 440 protrudes from the first housing 400, in the implementation manner where the groove 430 is located at the bottom of the cofferdam 440 compared with the implementation manner of directly forming the groove 430 by recessing on the first housing 400 without the cofferdam 440, the cofferdam 440 can first separate most of the water entering between the front shell and the first housing, reducing the amount of water in contact with the waterproof member 300.

[0048] It should be noted that the waterproof member 300 has multiple implementation manners. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, the present application provides a preferred implementation manner.

[0049] Please refer to Figure 3 and Figure 6 , the waterproof member 300 includes a first waterproof part 320; the first waterproof part 320 is adapted to the waterproof level 420 and is disposed at the waterproof level 420, or the first waterproof part 320 is press-fitted at the waterproof level 420.

[0050] In this embodiment, the adaptation of the first waterproof part 320 to the waterproof level 420 is not limited. Preferably, its shape is the same as that of the waterproof level 420 and can completely cover the through hole 410 to achieve the purpose of closing the through hole 410. In addition, the first waterproof part 320 can also be press-fitted at the waterproof level 420. In such an implementation manner, in addition to being able to close the through hole 410, it can also strengthen the waterproof effect. Specifically, it can prevent water from flowing into the through hole 410 through the gap outside the first waterproof part 320, and this implementation manner can also further prevent the waterproof member 300 from loosening or falling off.

[0051] It should be noted that, in addition to the above implementation manners of the waterproof member 300, there are other implementation manners. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, this application provides a preferred implementation manner.

[0052] Optionally, the waterproof member 300 includes a second waterproof portion 330, and the second waterproof portion 330 is disposed in the through hole 410.

[0053] In this embodiment, the second waterproof portion 330 is disposed in the through hole 410, so that the waterproof member 300 can seal the through hole 410. In the implementation manner where the waterproof member 300 includes a first waterproof portion 320 and a second waterproof portion 330, since the first waterproof portion 320 is disposed at the water level 420 and the second waterproof portion 330 is disposed in the through hole 410, therefore, compared with the implementation manner where only the second waterproof portion 330 is disposed in the through hole 410, the former has a better waterproof effect, because in the former, the second waterproof portion 330 further seals the inside of the through hole 410 on the basis that the first waterproof portion 320 seals the orifice of the through hole 410.

[0054] It should be noted that a protection door 500 is often provided in the safety socket to prevent foreign objects or water from entering the socket. Therefore, it is required that the waterproof member 300 does not affect the movement of the protection door 500 when the plug pin pushes the protection door 500. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, this application provides a preferred implementation manner.

[0055] Please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , a protection door 500 is provided between the front shell 100 and the first housing 400; a guide groove 600 is provided on the front shell 100 or the first housing 400 or between the front shell 100 and the first housing 400, and the guide groove 600 is used to make the protection door 500 move in a preset direction; the lower end of the guide groove 600 is not lower than the waterproof member 300.

[0056] In this embodiment, the lower end of the guide groove 600 is not lower than the waterproof member 300, so that when the protection door 500 is pushed by the plug pin, its moving trajectory will not pass through the waterproof member 300. Therefore, the waterproof member 300 will not affect the movement of the protection door 500.

[0057] It should be noted that the elastic opening and closing portion 310 has various implementation manners. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, this application provides a preferred implementation manner.

[0058] Please refer to Figure 7 and Figure 8, the elastic opening and closing part 310 includes a first elastic sub - part 311 and a second elastic sub - part 312 that abut against each other when the plug pins are not inserted; at least one end of the first elastic sub - part 311 and the second elastic sub - part 312 is connected.

[0059] In this embodiment, the elastic opening and closing part 310 is not limited. Preferably, it can be made of rubber. At the same time, the other parts of the waterproof part 300 can be made of rubber or other rigid materials. When the plug pins are not inserted, its first elastic sub - part 311 and second elastic sub - part 312 abut against each other, enabling it to close the through - hole 410. The first elastic sub - part 311 and the second elastic sub - part 312 can be connected at both ends or at one end, and the connection method can be integrally formed. When the first elastic sub - part 311 and the second elastic sub - part 312 are integrally formed at one end, during production, the waterproof part 300 can be cut from the edge inwards, without the need to cut from the middle, and the first elastic sub - part 311 and the second elastic sub - part 312 can also be formed, reducing the requirement for pre - positioning the cutting position.

[0060] It should be noted that the elastic opening and closing part 310 has various implementation manners. The specific implementation manners that meet the above requirements are not limited in this embodiment. For the convenience of understanding, this application provides a preferred implementation manner.

[0061] Please refer to Figure 7 and Figure 8 , the waterproof part 300 includes a first waterproof part 320 and a second waterproof part 330; the first waterproof part 320 is disposed at the waterproof level 420, and the second waterproof part 330 is disposed at the through - hole 410; the elastic opening and closing part 310 is formed between the first waterproof part 320 and the second waterproof part 330.

[0062] In this embodiment, the elastic opening and closing part 310 is formed between the first waterproof part 320 and the second waterproof part 330, so that both the first waterproof part 320 and the second waterproof part 330 can close the through - hole 410 when the plug pins do not open the elastic opening and closing part 310. In the implementation manner where the elastic opening and closing part 310 includes a first elastic sub - part 311 and a second elastic sub - part 312 that abut against each other when the plug pins are not inserted, and the elastic opening and closing part 310 is formed between the first waterproof part 320 and the second waterproof part 330, at least one end of the first elastic sub - part 311 and the second elastic sub - part 312 can be connected to the first waterproof part 320 or the second waterproof part 330, and the connection method can be integrally formed.

[0063] In summary, the safety socket provided by the embodiment of the present application includes a face shell 100, a bottom shell 200, and a waterproof member 300. A first housing 400 is provided between the face shell 100 and the bottom shell 200; the first housing 400 is provided with a through hole 410 and a waterproof level 420; the orifice of the through hole 410 is located within the waterproof level 420, or the orifice of the through hole 410 coincides with the waterproof level 420; the waterproof member 300 is disposed at the waterproof level 420 and / or the through hole 410 to close the through hole 410; the waterproof member 300 includes an elastic opening and closing portion 310, and the elastic opening and closing portion 310 is in a closed state when the plug pins are not inserted, and the elastic opening and closing portion 310 is opened by the plug pins and is in interference fit with the side surfaces of the plug pins when the plug pins are inserted.
