[0045] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0049] Electric shock injuries, especially those caused by water entering sockets, are common during daily electricity use. Sockets are ubiquitous in work and living spaces; if water is accidentally spilled on them, the live parts may become submerged, increasing the risk of electric shock during use. While current safety standards require that the live parts of sockets be concealed inside the socket housing when no plug is inserted, water can still enter the socket if it is spilled or accidentally submerged. Inserting a plug into a water-filled socket can lead to electric shock. Although using a water-filled socket does not necessarily result in electric shock, the risk is undeniably higher for a water-filled socket compared to a dry one. Therefore, current technology needs further improvement.

[0050] To address the aforementioned issues, this patent provides a safety socket designed to prevent water from entering the socket when it is not in use.

[0051] 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.

[0052] Please see Figure 1 A safety socket includes a faceplate unit 100, which includes a first housing 110 with a socket 111 for inserting a plug pin; a bottom housing 200 disposed below the first housing 110; a protective door 300 disposed between the first housing 110 and the bottom housing 200; when the plug pin is not inserted into the socket, the protective door 300 abuts against the inner surface of the first housing 110 and blocks the socket 111; and a drive structure 400 including a drive member 410 and a guide portion 420. The drive member 410 is disposed on the protective door 300 and / or the first housing 110 and is used to drive the protective door 300 to adhere to the first housing 110; the guide portion 420 is disposed on the faceplate unit 100 and is used to guide the movement direction of the protective door 300 when the plug pin is inserted into or removed from the socket 111.

[0053] In this embodiment, the first housing 110 of the faceplate unit 100 can block most of the water from entering the first housing 110. A protective door 300 is disposed between the first housing 110 and the bottom housing 200, allowing the protective door 300 to prevent water from entering the socket 111. When the plug pins are not inserted into the socket, the protective door 300 abuts against the inner surface of the first housing 110 and seals the socket 111, effectively preventing water from entering the socket 111. The protective door 300 abuts against the inner surface of the first housing 110 in various ways, such as the entire protective door abutting or the protective door 300 abutting partially. Whether it abuts entirely or partially, as long as the requirement of sealing the socket 111 is met, it is acceptable.

[0054] The driving component 410 of the driving structure 400 drives the protective door 300 to attach to the first housing 110, so that when the plug pins are not inserted, the protective door 300 can attach to the first housing 110 to block the socket 111, or when the plug pins are pulled out, the protective door 300 can return to the position of blocking the socket 111 when the plug pins are not inserted.

[0055] The guide portion 420 of the drive structure 400 can guide the movement direction of the protective door 300 when the plug pins are inserted into or removed from the socket 111, so that when the plug pins are inserted into the socket 111, the protective door 300 is guided to move in the direction that allows the plug pins to be inserted, or when the plug pins are removed, the protective door 300 is guided to move in the direction that blocks the socket 111.

[0056] This solves the problem of water entering socket 111 when the socket is not in use.

[0057] It should be noted that the plug prongs are inserted into the socket 111 of the first housing 110, while the terminals and other structures of the socket are located inside the bottom housing 200. Therefore, the plug prongs need to be able to pass through the protective door 300 so that the plug prongs can be electrically connected to the safety socket. This embodiment does not limit the specific implementation method that meets the above requirements. For ease of understanding, this application provides a preferred implementation method.

[0058] Please see Figure 6 and Figure 7 The protective door 300 is provided with a through hole 310 for the plug pins to pass through; the through hole 310 is misaligned with the socket 111 when the plug pins are not inserted into the socket, so that the protective door 300 blocks the socket 111.

[0059] In this embodiment, the protective door 300 is provided with a through hole 310 for the plug pins to pass through, so that the plug pins can be electrically connected to the safety socket. In addition, when the plug pins are not inserted into the socket, the through hole 310 is misaligned with the socket 111, thereby achieving the effect of the protective door 300 blocking the socket 111.

[0060] It should be noted that, based on the aforementioned technical solution of using the driving component 410 of the driving structure 400 to drive the protective door 300 to attach to the first housing 110, there is still a technical problem of how the driving component 410 drives the protective door 300 to attach to the first housing 110. In order to solve the above problem, the following solution is provided.

[0061] Please see Figure 1 The driving component 410 includes a first magnet 411 disposed on the protective door 300 and a second magnet 412 disposed on the face shell unit 100; the first magnet 411 and the second magnet 412 attract or repel each other so that the protective door 300 is attached to the first shell 110.

[0062] In this embodiment, a first magnet 411 and a second magnet 412 are provided on the protective door 300 and the face shell unit 100. By utilizing the mutual attraction or repulsion between the first magnet 411 and the second magnet 412, the protective door 300 is attached to the first shell 110, thereby achieving the technical effect of the driving member 410 driving the protective door 300 to attach to the first shell 110.

[0063] It should be noted that the protective door 300 is attached to the first housing 110 by means of a first magnet and a second magnet 412. However, to achieve the effect of the protective door 300 being attached to the first housing 110 by the mutual attraction or repulsion of the first magnet 411 and the second magnet 412, it is necessary to further determine the positions of the first magnet 411 and the second magnet 412. This embodiment does not limit the specific implementation method that meets the above requirements. For ease of understanding, this application provides a preferred implementation method.

[0064] Optionally, the faceplate unit 100 further includes a second housing, with a protective door 300 disposed between the first housing 110 and the second housing; a second magnet 412 disposed in the second housing and repelling the first magnet 411; and the first magnet 411 located horizontally between the second magnet 412 and the socket 111.

[0065] In this embodiment, the second magnet 412 is disposed on the second housing, and the first magnet 411 is disposed between the second magnet 412 and the socket 111 in the horizontal direction, so that the protective door 300 can adhere to the first housing 110 and block the socket 111 under the mutual repulsion of the first magnet 411 and the second magnet 412.

[0066] It should be noted that, based on the aforementioned technical solution of mutual repulsion between the first magnet 411 and the second magnet 412, there is also a further technical solution on how to achieve the above requirements by mutual attraction between the first magnet 411 and the second magnet 412. To solve the above problems, the following solution is further provided.

[0067] Please see Figure 1-3The second magnet 412 is disposed in the first housing 110 and is attracted to the first magnet 411.

[0068] In this embodiment, a first magnet 411 is disposed on the protective door 300, and a second magnet 412 is disposed on the first housing 110. The first magnet 411 and the second magnet 412 attract each other, so that the protective door 300 can be attached to the first housing 110 and block the socket 111.

[0069] It should be noted that, based on the aforementioned technical solution of using the first magnet 411 and the second magnet 412 to drive the protective door 300 to attach to the first housing 110, there is still a technical problem of how to fix the first magnet 411 and the second magnet 412. In order to solve the above problem, the following solution is provided.

[0070] Please see Figure 2-3 and Figure 6-7 The protective door 300 is provided with a first receiving groove for fixing the first magnet 411; the face shell unit 100 is provided with a second receiving groove for fixing the second magnet 412.

[0071] In this embodiment, a first receiving groove for fixing the first magnet 411 is provided on the protective door 300, and a second receiving groove for fixing the second magnet 412 is provided on the face shell unit 100, so that the first magnet 411 and the second magnet 412 can be fixed to the protective door 300 and the face shell unit 100 respectively.

[0072] It should be noted that the first magnet 411 is fixed to the first receiving groove of the protective door 300, and the second magnet 412 is fixed to the second receiving groove of the protective door 300. Since the attractive or repulsive forces of the first magnet 411 and the second magnet 412 are not significant, the distance between the first magnet 411 fixed to the first receiving groove and the second magnet 412 fixed to the second receiving groove needs to be relatively close. This embodiment does not limit the specific implementation method that satisfies the above requirements. For ease of understanding, this application provides a preferred implementation method.

[0073] Optionally, the thickness of the bottom of the first receiving groove is between 0.03 mm and 2 mm.

[0074] In this embodiment, the thickness of the bottom of the first receiving groove is between 0.03mm and 2mm, which makes the distance between the first magnet 411 fixed in the first receiving groove and the second magnet 412 fixed in the second receiving groove relatively close. Thus, the attraction or repulsion of the first magnet 411 and the second magnet 412 can drive the protective door 300 to attach to the first housing 110 and block the insertion hole 111.

[0075] It should be noted that, based on the aforementioned technical solution of driving the protective door 300 with the first magnet 411 and the second magnet 412, there is still a technical problem of how to set up the first magnet 411 and the second magnet 412 and drive the protective door 300. In order to solve the above problem, the following solution is provided.

[0076] Please see Figure 1-3 and Figure 6-7 The protective door 300 is provided with a first magnet groove 320, and a first magnet 411 is provided in the first magnet groove 320; the first housing 110 is provided with a second magnet groove 330, and a second magnet 412 is provided in the second magnet groove 330; the first magnet groove 320 and the second magnet groove 330 are aligned with each other when the protective door 300 blocks the insertion hole 111; the first magnet 411 and the second magnet 412 attract each other.

[0077] In this embodiment, by providing a first magnet groove 320 and a second magnet groove 330 on the protective door 300 and the first housing 110, and by respectively placing the first magnet 411 and the second magnet 412 in the first magnet groove 320 and the second magnet groove 330, and by ensuring that the positions of the first magnet groove 320 and the second magnet groove 330 are aligned with each other when the protective door 300 blocks the insertion hole 111, the protective door 300 can adhere to the first housing 110 and block the insertion hole 111 under the mutual attraction of the first magnet 411 and the second magnet 412.

[0078] It should be noted that, based on the aforementioned technical solution of driving the protective door 300 by the mutual attraction of the first magnet 411 and the second magnet 412, there is a further technical problem of how to drive the protective door 300 by the mutual repulsion of the first magnet 411 and the second magnet 412. In order to solve the above problem, the following solution is provided.

[0079] Please see Figure 9 The protective door 300 is provided with a first magnet groove 320, and a first magnet 411 is provided in the first magnet groove 320; the face shell unit 100 includes a second shell, and a first shell 110 is provided above the second shell; the second shell is provided with a third magnet groove 350, and a second magnet 412 is provided in the third magnet groove 350; when the plug pin is inserted into the socket, the first magnet groove 320 is located between the third magnet groove 350 and the socket 111; the first magnet 411 and the second magnet 412 repel each other.

[0080] In this embodiment, by providing a third magnet groove 350 in the second housing, the first magnet 411 and the second magnet 412 are respectively disposed in the first magnet groove 320 and the third magnet groove 350. It is determined that when the plug pins are inserted into the socket, the first magnet groove 320 is located between the third magnet groove 350 and the socket 111, so that when the plug pins are pulled out, the protective door 300 can be reset to the position of blocking the socket 111 and attached to the first housing 110 under the mutual repulsion of the first magnet 411 and the second magnet 412.

[0081] It should be noted that the protective door 300 is attached to the first housing 110 and blocks the insertion hole 111 by means of a first magnet 411 and a second magnet 412 fixed to the first magnet groove 320. The first magnet groove 320 can be implemented in various ways. Among the implementations that meet the above requirements, the first magnet 411 fixed to the first magnet groove 320 needs to be able to stably attach the protective door 300 to the first housing 110 and block the insertion hole 111. This embodiment does not limit the specific implementation that meets the above requirements. For ease of understanding, this application provides a preferred implementation.

[0082] Please see Figure 7 The first magnet groove 320 is provided at both ends of the protective door 300.

[0083] In this embodiment, by providing first magnet grooves 320 at both ends of the protective door 300, and providing first magnets 411 in both first magnet grooves 320 at both ends, the driving action of the first magnets 411 and the second magnets 412 can be applied evenly to the protective door 300, so that the protective door 300 can be stably attached to the first housing 110 and block the insertion hole 111.

[0084] It should be noted that, based on the aforementioned technical solution of driving the protective door 300 by fixing the first magnet 411 and the second magnet 412 in the first magnet groove 320, there is still a technical problem of how to install the second magnet 412. In order to solve the above problem, the following solution is provided.

[0085] Optionally, the protective door 300 is provided with a first magnet groove 320, and a first magnet 411 is provided in the first magnet groove 320; the first magnet groove 320 is provided at one end of the protective door 300; the first housing 110 is provided with a magnet mounting protrusion, and a second magnet 412 is mounted on the magnet mounting protrusion, with the magnet mounting protrusion close to the first magnet groove 320.

[0086] In this embodiment, the magnet mounting protrusion is close to the first magnet groove 320, and the second magnet 412 is mounted on the magnet mounting protrusion, so that the driving action of the first magnet 411 and the second magnet 412 can act on the protective door 300. For example, the first magnet 411 and the second magnet 412 attract each other, so that when the plug pin is pulled out, the protective door 300 can return to the position of blocking the socket 111.

[0087] It should be noted that, besides the technical solution of setting the driving component 410 as a magnet, there are many other ways to implement the driving component 410. This embodiment does not limit the specific implementation method that meets the above requirements; for ease of understanding, this application provides a preferred implementation method.

[0088] Please see Figure 10 The driving component 410 is a spring 413, which has a first spring end and a second spring end opposite to each other. The first spring end is disposed on the protective door 300, and the spring 413 is used to elastically pull or elastically press the protective door 300 so that the protective door 300 is attached to the first housing 110.

[0089] In this embodiment, the driving component 410 is set as a spring 413, and one end of it is set on the protective door 300, so that the spring 413 can elastically pull or elastically press the protective door 300, thereby the protective door 300 is attached to the first housing 110 and blocks the socket 111.

[0090] It should be noted that the first spring end of spring 413 is disposed on the protective door 300 to elastically press or tighten the protective door 300. However, the function of spring 413 requires both ends to be disposed on components, so it is necessary to determine on which component the other end of spring 413 is disposed on. This embodiment does not limit the specific implementation method that satisfies the above requirements. For ease of understanding, this application provides a preferred implementation method.

[0091] Optionally, the end of the second spring is disposed on the first housing 110, and the spring 413 pulls the protective door 300 so that the protective door 300 is attached to the first housing 110.

[0092] In this embodiment, the second spring end of the spring 413 is disposed on the first housing 110, so that the function of the spring 413 can be performed. Furthermore, the way the spring 413 tightens the protective door 300 allows the protective door 300 to adhere to the first housing 110 and block the insertion hole 111.

[0093] It should be noted that, based on the aforementioned technical solution of spring 413 tightening the protective door 300, there is still a technical problem of how to achieve the elastic pressing of spring 413 against the protective door 300. To solve the above problem, the following solution is provided.

[0094] Please see Figure 10 The face shell unit 100 includes a third shell 130, and a first shell 110 is disposed above the third shell 130; the end of a second spring is disposed on the third shell 130, and the spring 413 elastically presses the protective door 300 so that the protective door 300 is attached to the first shell 110.

[0095] In this embodiment, by setting the end of the second spring on the third housing 130 located below the first housing 110, the spring 413 can elastically press the protective door 300 against the first housing 110, thereby attaching the protective door 300 to the first housing 110 and blocking the socket 111.

[0096] It should be noted that when the driving component 410 is set as a spring 413, it can elastically press or elastically pull the protective door 300 so that the protective door 300 adheres to the first housing 110 and blocks the insertion hole 111. When the spring 413 makes the protective door 300 adhere to the first housing 110, the protective door 300 needs to be able to adhere smoothly to the first housing 110. The specific implementation method to meet the above requirements is not limited in this embodiment. For ease of understanding, this application provides a preferred implementation method.

[0097] Optionally, there may be multiple springs 413, which are located at both ends of the protective door 300.

[0098] In this embodiment, multiple springs 413 are provided and located at both ends of the protective door 300, so that the protective door 300 can be stably attached to the first housing 110 to achieve the effect of blocking the socket 111.

[0099] It should be noted that, based on the aforementioned technical solution of using spring 413 to drive the protective door 300 to reset, there is still a technical problem of how to install spring 413. In order to solve the above problem, the following solution is provided.

[0100] Optionally, the protective door 300 has a first protective door end and a second protective door end, and a first spring end is disposed at the first protective door end; the first housing 110 is provided with a spring 413 mounting protrusion, and a second spring end is mounted on the spring 413 mounting protrusion, with the spring 413 mounting protrusion close to the first protective door end.

[0101] In this embodiment, a spring 413 mounting protrusion is provided on the first housing 110, the spring 413 mounting protrusion is close to the end of the first protective door, and the first spring end and the second spring end are respectively provided on the protective door 300 and the spring 413 mounting protrusion, so that the spring 413 can elastically press or elastically pull the protective door 300, thereby the protective door 300 is attached to the first housing 110 and blocks the insertion hole 111.

[0102] It should be noted that, based on the aforementioned technical solution of attaching the protective door 300 to the first housing 110 and blocking the socket 111, there is still a technical problem of how the protective door 300 blocks the socket 111. To solve the above problem, the following solution is provided.

[0103] Optionally, the upper surface of the protective door 300 is provided with a blocking protrusion 340, which is used to block the insertion hole 111.

[0104] In this embodiment, by providing a sealing protrusion 340 on the upper surface of the protective door 300, the protective door 300 can block the insertion hole 111 through the sealing protrusion 340 when it is attached to the first housing 110.

[0105] It should be noted that, based on the aforementioned technical solution of attaching the protective door 300 to the first housing 110 and sealing the insertion hole 111, there is a further technical problem of how to prevent the protective door 300 from moving too much when it moves, which would cause the protective door 300 to fail to reset. In order to solve the above problem, the following solution is provided.

[0106] Please see Figure 2 The first housing 110 is provided with limiting protrusions 112, which are located at both ends of the protective door 300.

[0107] In this embodiment, a limiting protrusion 112 is provided on the first housing 110, so that when the protective door 300 moves a large range, it will abut against the limiting protrusion 112 to restrict the movement of the protective door 300, thereby preventing the problem that the protective door 300 cannot be reset due to a large range of movement.

[0108] It should be noted that, based on the aforementioned technical solution that the protective door 300 resets to the position of blocking the socket 111 when the plug pins are pulled out and moves away when the plug pins are inserted so that the plug pins can be electrically connected to the socket, there is still a technical problem regarding the direction in which the protective door 300 moves. To solve the above problem, the following solution is provided.

[0109] Please see Figure 2 and Figure 4-5 The guide part 420 is provided with a guide groove 421, and the protective door 300 is provided with a guide protrusion 430 that is adapted to the guide groove 421. The guide protrusion 430 is embedded in the guide groove 421. The guide groove 421 and the guide protrusion 430 are used to move the protective door 300 in the direction of aligning or misaligning the insertion hole 111 and the through hole 310 when the protective door 300 moves.

[0110] In this embodiment, a guide protrusion 430 is provided on the protective door 300, and a guide groove 421 is provided on the guide portion 420. By embedding the guide protrusion 430 into the guide groove 421, the protective door 300 moves along the direction in which the insertion hole 111 and the through hole 310 are aligned or misaligned under the guidance of the guide protrusion 430 and the guide groove 421.

[0111] It should be noted that the protective door 300 moves along the misalignment or alignment direction of the insertion hole 111 and the through hole 310 through the guiding action of the guide groove 421 and the guide protrusion 430. This guiding action only takes effect when all the plug pins are inserted, preventing it from acting when a single spike or metal pin is inserted, thus allowing the protective door 300 to move along the misalignment or alignment direction of the insertion hole 111 and the through hole 310. This embodiment does not limit the specific implementation method that satisfies the above requirements; for ease of understanding, this application provides a preferred implementation method.

[0112] Please see Figure 6 The guide protrusion 430 is located in the middle of both sides of the protective door 300 so that the protective door 300 swings when a single plug protrusion is inserted into the socket 111.

[0113] In this embodiment, by providing guide protrusions 430 in the middle of both sides of the protective door 300, when a single plug pin, a single spike, or a single metal needle is inserted into the socket 111, the protective door 300 swings without moving in the direction of alignment or misalignment between the socket 111 and the through hole 310, so that a single plug pin, a single spike, or a single metal needle cannot be electrically connected to the socket.

[0114] It should be noted that, based on the aforementioned technical solution of guiding the protective door 300 to move along the direction of misalignment or alignment of the insertion hole 111 and the through hole 310 using the guide groove 421 and the guide protrusion 430, there is a further technical problem regarding how the guide groove 421 and the guide protrusion 430 guide the protective door 300 to move along the direction of misalignment or alignment of the insertion hole 111 and the through hole 310. To solve the above problem, the following solution is further provided.

[0115] Please see Figure 2 and Figure 4-5 The guide groove 421 includes a transverse groove 421a and a sinking groove 421b; the sinking groove 421b has a first sinking groove end 421b-1 and a second sinking groove end 421b-2; the first sinking groove end 421b-1 is close to the first housing 110, and the second sinking groove end 421b-2 extends away from the first housing 110; the second sinking groove end 421b-2 is connected to the transverse groove 421a.

[0116] In this embodiment, the guide protrusion 430 and the transverse sliding groove 421a of the guide groove 421 achieve the effect of guiding the protective door 300 to move in the direction of misalignment or alignment with the insertion hole 111 and the through hole 310. In addition, the recessed groove 421b, which is connected to the transverse sliding groove 421a, allows the protective door 300 to come close to the first housing 110, thereby attaching to the first housing 110 and blocking the insertion hole 111.

[0117] It should be noted that the transverse groove 421a and the recessed groove 421b of the guide groove 421 allow the protective door 300 to move along the direction of misalignment or alignment of the insertion hole 111 and the through hole 310, and also allow the protective door 300 to adhere to the first housing 110 and block the insertion hole 111. However, when the plug pins are not fully inserted into the insertion hole 111, the protective door 300 needs to adhere to the first housing 110 and not move along the direction of alignment of the insertion hole 111 and the through hole 310. This embodiment does not limit the specific implementation method that satisfies the above requirements. For ease of understanding, this application provides a preferred implementation method.

[0118] Please see Figure 2 and Figure 4-5 The sinking groove 421b and the transverse sliding groove 421a are in a straight line, and the angle between the direction of the pin insertion hole 111 and the sinking groove 421b is smaller than the angle between the direction of the pin insertion hole 111 and the transverse sliding groove 421a.

[0119] In this embodiment, the sinking groove 421b and the transverse groove 421a are in a straight line. The angle between the direction of the plug insertion into the socket 111 and the sinking groove 421b is smaller than the angle between the direction of the plug insertion into the socket 111 and the transverse groove 421a. This ensures that when the plug pin is not fully inserted into the socket 111, the protective door 300 adheres to the first housing 110 and does not move along the direction in which the socket 111 and the through hole 310 are aligned.

[0120] It should be noted that, based on the aforementioned technical solution of the guide groove 421 including the transverse groove 421a and the sinking groove 421b, there is a further technical problem of how to make the guide protrusion 430 move smoothly from the sinking groove 421b to the transverse groove 421a. In order to solve the above problem, the following solution is provided.

[0121] Please see Figure 2 and Figure 4-5 The guide groove 421 also includes an arc-shaped groove 421c, which is located at the end 421b-2 of the second sinking groove and the transverse groove 421a.

[0122] In this embodiment, by providing an arc-shaped groove 421c at the connection between the end 421b-2 of the second sinking groove and the transverse groove 421a, the guide protrusion 430 can smoothly move from the sinking groove 421b to the transverse groove 421a.

[0123] It should be noted that inserting a single prong into a socket can easily cause a safety accident, so a safety socket is needed to prevent the insertion of a single prong. This embodiment does not limit the specific implementation method that meets the above requirements; for ease of understanding, this application provides a preferred implementation method.

[0124] Please see Figure 8 The safety socket is provided with a stop structure 500, which includes a first stop part 510 and a second stop part 520. The protective door 300 has a first protective door end, the first stop part 510 is disposed at the first protective door end, and the second stop part 520 is disposed at the first housing 110. The first stop part 510 and the second stop part 520 are used to restrict the movement of the protective door 300 and prevent the single plug from being electrically connected to the safety socket when a single plug is inserted into the socket 111 away from the first protective door end.

[0125] In this embodiment, by providing a first stop 510 and a second stop 520 on the protective door and the first housing 110, when a single plug is inserted into the socket 111 away from the end of the first protective door, the first stop 510 abuts against the second stop 520, thereby restricting the movement of the protective door 300, so that the plug pin cannot pass through the protective door 300 to make an electrical connection with the socket.

[0126] It should be noted that, based on the technical solution of preventing a single pin from being inserted into the socket 111 away from the end of the first protective door, there is also a further technical problem of preventing a single pin from being inserted into the socket 111 close to the end of the first protective door. To solve the above problem, the following solution is further provided.

[0127] Please see Figure 8 The faceplate unit 100 includes a second housing 120, and a first housing 110 is disposed above the second housing 120. The stop structure 500 includes a third stop portion 530. The third stop portion 530 is disposed in the second housing 120. The first stop portion 510 and the third stop portion 530 are used to restrict the movement of the protective door 300 and prevent the single plug from being electrically connected to the safety socket when a single plug is inserted into the socket 111 near the end of the first protective door.

[0128] In this embodiment, by providing a first stop 510 and a third stop 530 on the protective door 300 and the second housing 120, when a single plug is inserted into the socket 111 near the end of the first protective door, the first stop 510 abuts against the third stop 530, thereby restricting the movement of the protective door 300, so that the plug pin cannot pass through the protective door 300 to make an electrical connection with the socket.

[0129] It should be noted that, based on the aforementioned technical solution of using the stop structure 500 to prevent a single pin from being inserted into the protective door, there is a further technical problem of how to make the plug pin of the insertion socket 111 extend deeper to pass through the second housing 120 and make an electrical connection with the component below the second housing 120. To solve the above problem, the following solution is further provided.

[0130] Please see Figure 8 The first stop 510 is provided with a relief groove 511, the second housing 120 is provided with a protective door recess 121, and the third stop 530 is provided in the protective door recess 121. When the plug pin is inserted into the socket 111, the protective door 300 avoids the third stop 530 through the relief groove 511. When the plug pin is inserted into the socket 111, the protective door 300 is embedded in the protective door recess 121.

[0131] In this embodiment, by providing a protective door recess 121 in the second housing 120, the protective door 300 can be embedded in the protective door recess 121 of the second housing 120 when the entire plug prongs are inserted into the socket 111. As a result, less space is needed between the first housing 110 and the second housing 120 for the protective door, and the depth between the first housing 110 and the second housing 120 is reduced. This allows the entire plug prongs to be inserted deeper into the socket 111, passing through the second housing 120 and achieving electrical connection with the components below the second housing 120.

[0132] Meanwhile, since the first stop part 510 has a clearance groove 511, when the protective door 300 is embedded in the protective door recess 121, it can avoid the third stop part 530.

[0133] It should be noted that the third stop part 530 itself also has the function of the aforementioned limiting protrusion 112, which can prevent the protective door 300 from moving too much, causing the protective door 300 to be unable to reset.

[0134] In summary, the safety socket provided in this application includes a face shell unit 100, which includes a first shell 110 with a socket 111 for inserting a plug pin; a bottom shell 200 disposed below the first shell 110; a protective door 300 disposed between the first shell 110 and the bottom shell 200; when the plug pin is not inserted into the socket, the protective door 300 abuts against the inner surface of the first shell 110 and blocks the socket 111; and a drive structure 400 including a drive member 410 and a guide portion 420. The drive member 410 is disposed on the protective door 300 and / or the first shell 110 and is used to drive the protective door 300 to adhere to the first shell 110. The guide portion 420 is disposed on the face shell unit 100 and is used to guide the movement direction of the protective door 300 when the plug pin is inserted into or removed from the socket 111. This solves the problem of water entering socket 111 when the socket is not in use.

[0135] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
