[0002] As people's demands for electrical safety increase, higher requirements are being placed on the safety of electrical connections in electrical accessories, such as sockets. Currently, most electrical accessories on the market use plugs where both the L and N pins simultaneously open the safety shutter, then connect to the socket's current-carrying socket to draw power. When a conductive object is inserted into the socket's L pin, the safety shutter may open, exposing the socket's L-pin current-carrying component and posing a safety risk. Summary of the Invention

[0003] The purpose of this invention is to overcome at least one defect of the prior art and provide an N-pole driven protective door structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

A first limiting plate is provided at the end of the first protective door away from the first driving inclined surface. A first N-pole hole is provided between the first driving inclined surface and the first limiting plate.

[0006] The first protective door can move between a first position and a second position. When the first protective door is in the first position, the first driving inclined surface closes the N-hole of the first panel, the first N-hole is offset from the N-hole of the first panel, and the first limiting plate closes the L-hole of the first panel.

[0013] Furthermore, a first base baffle and a second base baffle are disposed opposite to each other inside the base. The first protective door and the second protective door are respectively disposed on both sides of the line connecting the first base baffle and the second base baffle. The first limiting part and the second limiting part extend into the space between the first base baffle and the second base baffle. An elastic member is connected between the first limiting part and the second limiting part to drive the first limiting part and the second limiting part to move away from each other, so that the first limiting part and the second limiting part are respectively limited by the first base baffle and the second base baffle.

[0014] Furthermore, the first base baffle includes a first vertical baffle and a first horizontal baffle connected to the first vertical baffle, and the second base baffle includes a second horizontal baffle connected to the second vertical baffle. The first horizontal baffle and the second horizontal baffle are respectively located above the first limiting part and the second limiting part, and the first vertical baffle and the second vertical baffle respectively axially limit the first limiting part and the second limiting part.

[0015] Furthermore, the base is provided with a first mounting groove corresponding to the first transverse baffle, and the base is provided with a second mounting groove corresponding to the second transverse baffle. The first limiting part and the second limiting part can extend into the first mounting groove and the second mounting groove, and the first mounting groove and the second mounting groove limit the sliding of the first limiting part and the second limiting part.

[0016] Furthermore, the distance the first limiting part moves from the first position to the second position within the first mounting groove is less than the distance the first transverse baffle extends from the first vertical baffle towards the second vertical baffle, thereby limiting the first limiting part by the first transverse baffle; the distance the second limiting part moves from the third position to the fourth position within the second mounting groove is less than the distance the second transverse baffle extends from the second vertical baffle towards the first vertical baffle, thereby limiting the second limiting part by the second transverse baffle.

[0017] Furthermore, a first E-hole is provided between the first N-hole and the first limiting plate, and the second panel E-hole is located between the first panel N-hole and the first panel L-hole.

[0020] Furthermore, guide ribs are provided around both the N-hole and L-hole of the first panel on the side facing the base. The guide rib of the N-hole of the first panel has a first beveled surface, the direction of which is consistent with the direction of the first driving bevel. When the first protective door is in the first position, at least a portion of the first driving bevel is in contact with the first beveled surface; and / or,

[0021] The panel facing the base is provided with guide ribs around the second panel N-hole, the second panel L-hole and the second panel E-hole. The guide rib of the second panel N-hole is provided with a second oblique surface. The direction of the second oblique surface is consistent with the direction of the oblique surface of the second driving oblique surface. When the second protective door is in the third position, at least part of the second driving oblique surface is in contact with the second oblique surface.

[0022] Furthermore, the base is provided with a positioning groove, the panel is provided with a positioning post, and the panel and the base are fastened together by the positioning post and the positioning groove.

[0023] Furthermore, the surface of the first limiting plate opposite to the L-hole of the first panel is a plane, and the surface of the second limiting plate opposite to the L-hole of the first panel is a plane.

[0025] This utility model adopts a structure with an N-pole driven protection door. It has a first protection door for protecting two-pole sockets and a second protection door for protecting three-pole sockets. Both the first and second protection doors are driven by a drive slope only for the N-pole hole. The corresponding protection door can only be driven by the N-pole pin. It does not adopt a structure in which the L and N pins of the plug drive the protection door at the same time. This can effectively avoid the risk of accidentally touching the live L-pole socket sleeve, reduce the failure rate of long-term use, reduce maintenance costs, thereby improving the safety performance of electrical accessories and protecting personal and property safety.

[0026] In addition, this utility model adopts a structure in which the sliding directions of the first protective door and the second protective door are opposite, thereby saving space and facilitating miniaturization design.

[0027] In addition, the first and second protective doors can return to their original positions by sharing a single elastic component, saving parts and facilitating installation.

[0028] Furthermore, a first base baffle and a second base baffle are provided to limit the first limiting part of the first protective door and the second limiting part of the second protective door, resulting in a compact structure. Further, a first transverse baffle and a second transverse baffle are provided to prevent the first and second protective doors from popping up from the base.

[0051] 4. Elastic component. Detailed Implementation

[0052] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0053] The socket includes a socket body and a protective door structure 1 for N-pole drive. The socket body includes multiple clamping arm structures of socket sleeves. One end of each socket sleeve is connected to the power supply of the line, and the other end is used to connect the plug. The socket sleeve has a clamping effect and can cooperate with the plug to achieve clamping connection, which can fix and limit the plug.

[0054] like Figure 1As shown, this application provides an N-pole driven protective door structure 1, which cooperates with the socket body's socket sleeve to block the socket sleeve when the socket is not in use, preventing small objects from contacting the socket sleeve and causing safety issues.

[0055] like Figures 1 to 16 As shown, the N-pole driven protective door structure 1 includes a base 12 and a panel 11 connected to the base 12. A first protective door 2 and a second protective door 3 are disposed between the base 12 and the panel 11. The panel 11 is provided with a first panel N-pole hole 1021 and a first panel L-pole hole 1022 spaced apart. A first driving inclined surface 21 is provided at one end of the first protective door 2 for sliding on the base 12 under force. A first limiting plate 222 is provided at the end of the first protective door 2 away from the first driving inclined surface 21. A first N-pole hole 221 is provided between the first driving inclined surface 21 and the first limiting plate 222.

[0056] The first protective door 2 can move between a first position and a second position. When the first protective door 2 is in the first position, the first driving inclined surface 21 closes the first panel N-hole 1021, the first N-hole 221 is offset from the first panel N-hole 1021, and the first limiting plate 222 closes the first panel L-hole 1022. When the first protective door 2 is in the second position, the first N-hole 221 corresponds to the first panel N-hole 1021, and the first limiting plate 222 is offset from the first panel L-hole 1022 to release the closure.

[0057] The panel 11 is also provided with a triangular arrangement of a second panel N-pole hole 1031, a second panel L-pole hole 1032, and a second panel E-pole hole 1033. The second protective door 3 is provided with a second driving slope 31 at one end away from the first limiting plate 222, which is used to drive the second protective door 3 to slide on the base 12 under force. The second protective door 3 is provided with a second limiting plate 322 at the end away from the second driving slope 31. A second L-pole hole 321 is provided between the second driving slope 31 and the second limiting plate 322.

[0058] The second protective door 3 can move between the third position and the fourth position. When the second protective door 3 is in the third position, the second driving inclined surface 31 closes the N-hole 1031 of the second panel, and the second limiting plate 322 closes the L-hole 1032 of the second panel. The second L-hole 321 is offset from the L-hole 1032 of the second panel. When the second protective door 3 is in the fourth position, the second limiting plate 322 is offset from the N-hole 1031 of the second panel to release the closure. The second L-hole 321 corresponds to the L-hole 1032 of the second panel.

[0059] This application adopts a protection door structure 1 driven by the N pole, which includes a first protection door 2 for protecting two-prong sockets and a second protection door 3 for protecting three-prong sockets. Both the first protection door 2 and the second protection door 3 are provided with driving slopes only for the N pole holes. The corresponding protection door can only be driven by the N pole pin. The structure of simultaneously driving the protection door by the L and N pins of the plug is not adopted. This can effectively avoid the risk of accidentally touching the live socket L pole sleeve, reduce the failure rate of long-term use, reduce maintenance costs, thereby improving the safety performance of electrical accessories and protecting personal and property safety.

[0060] like Figure 3 , 4 As shown in Figures 6 and 10, in an optional embodiment of the protective door structure, a first protective door 2 and a second protective door 3 are provided in the cavity of the base 12. The first protective door 2 and the second protective door 3 are slidably connected to the base 12. The first protective door 2 and the second protective door 3 are arranged opposite to each other and are used to close or unclose the panel hole.

[0061] Preferably, the first protective door 2 and the second protective door 3 slide in parallel and opposite directions on the base 12. Because this application employs a structure where the sliding directions of the first and second protective doors are opposite, space is saved, facilitating miniaturization design.

[0062] Specifically, the first driving inclined surface 21 slopes downward from the N-hole 1021 of the first panel towards the L-hole 1022 of the first panel. Driven by a driving force, the first driving inclined surface 21 can move the first protective door 2 from the first position to the second position. The second driving inclined surface 311 slopes downward from the N-hole 1031 of the second panel away from the L-hole 1032 of the second panel. Driven by a driving force, the second driving inclined surface 31 can move the second protective door 3 from the third position to the fourth position. That is, the direction in which the first protective door 2 slides from the first position to the second position is opposite to the direction in which the second protective door 3 slides from the third position to the fourth position. The surface of the first limiting plate 222 opposite to the L-hole 1022 of the first panel is a plane, and the surface of the second limiting plate 322 opposite to the L-hole 1022 of the first panel is also a plane.

[0063] Preferably, an elastic component 4 is provided between the first protective door 2 and the second protective door 3, and the elastic component 4 is connected to the first protective door 2 and the second protective door 3.

[0064] This embodiment employs a structure where the elastic component 4 cooperates with the protective door, enabling the protective door to quickly and automatically return to its original position, preventing accidental contact with the live socket. Furthermore, the first and second protective doors share a single elastic component for return, saving parts and facilitating installation. Of course, as a modified embodiment, the first and second protective doors could each be equipped with a separate elastic component.

[0065] like Figure 4 , 6 As shown in Figure 10, a first limiting part 23 is provided on the side of the first protective door 2 near the second protective door 3, and a second limiting part 33 is provided on the side of the second protective door 3 near the first protective door 2. The first limiting part 23 and the second limiting part 33 are arranged opposite to each other, and an elastic member 4 is provided between the first limiting part 23 and the second limiting part 33. The elastic member 4 is connected to the first limiting part 23 and the second limiting part 33, so that the first protective door 2 and the second protective door 3 can maintain a stable balance and will not come out, and the first protective door 2 and the second protective door 3 can quickly return to their original positions.

[0066] Specifically, the first limiting part 23 includes an integrally formed first limiting arm 231 and a first engaging arm 232. The first limiting arm 231 is fixedly connected to the side of the first protective door 2 and cooperates with the base 12 to limit the sliding position of the first protective door 2. The first engaging arm 232 extends into the elastic member 4 and limits the elastic member 4 to prevent it from coming out. The cross-section of the first engaging arm 232 is preferably circular, but other shapes can also be selected, as long as they can extend into the elastic member 4 and limit the elastic member 4.

[0067] The second limiting part 33 includes an integrally formed second limiting arm 331 and a second engaging arm 332. The second limiting arm 331 is fixedly connected to the side of the second protective door 3 and cooperates with the base 12 to limit the sliding position of the second protective door 3. The second engaging arm 332 extends into the elastic member 4 and limits the elastic member 4 to prevent it from coming out. The cross-section of the second engaging arm 332 is preferably circular, but other shapes can also be selected as long as they can extend into the elastic member 4 and limit the elastic member 4.

[0068] Preferably, the first locking arm 232 and the second locking arm 332 have a chamfer at the end facing the elastic component 4 to facilitate the installation of the elastic component 4.

[0069] Preferred, such as Figure 4As shown, the first protective door 2 includes a first driving inclined surface 21 and a first flat plate portion 22 connected to the first driving inclined surface 21. The end of the first flat plate portion 22 away from the first driving inclined surface 21 has a first groove. The flat surface at the bottom of the first groove serves as the first limiting plate 222. Thus, the distance from the first limiting plate 222 to the panel 11 is less than the distance from the first flat plate portion 22 to the panel 11, and the movement of the inserted conductor is limited to a certain extent by the sidewall of the first groove. Preferably, the distance difference h between the side of the first limiting plate 222 facing the panel 11 and the side of the first flat plate portion 22 facing the panel 11 is in the range 0 < h ≤ 0.5 mm. Figure 6 As shown, the second protective door 3 includes a second driving inclined surface 31 and a second flat plate portion 32 connected to the second driving inclined surface 31. The end of the second flat plate portion 32 away from the second driving inclined surface 31 has a second groove. The flat surface at the bottom of the second groove serves as the second limiting plate 322. Thus, the distance from the second limiting plate 322 to the panel 11 is less than the distance from the second flat plate portion 32 to the panel 11, thereby limiting the movement of the inserted conductor to a certain extent through the sidewall of the second groove. Preferably, the distance difference H between the side of the second limiting plate 322 facing the panel 11 and the side of the second flat plate portion 32 facing the panel 11 is 0 < H ≤ 0.5 mm.

[0070] like Figure 3 , 9 As shown in Figure 10, in an optional embodiment of the base 12, a first base baffle 1211 and a second base baffle 1221 are disposed opposite each other within the base 12. A first protective door 2 and a second protective door 3 are respectively disposed on both sides of the line connecting the first base baffle 1211 and the second base baffle 1221. A first limiting part 23 and a second limiting part 33 extend between the first base baffle 1211 and the second base baffle 1221. An elastic member 4 connects between the first limiting part 23 and the second limiting part 33, driving the first limiting part 23 and the second limiting part 33 to move away from each other, thereby limiting the first limiting part 23 and the second limiting part 33 to the first base baffle 1211 and the second base baffle 1221 respectively. This embodiment provides a first base baffle 1211 and a second base baffle 1221 for limiting the first limiting part 23 of the first protective door 2 and the second limiting part 33 of the second protective door 3, resulting in a compact structure.

[0071] Furthermore, the first base baffle 1211 includes a first vertical baffle 12112 and a first horizontal baffle 12111 connected to the first vertical baffle 12112, and the second base baffle 1221 includes a second horizontal baffle 12211 connected to the second vertical baffle 12212. The first horizontal baffle 12111 and the second horizontal baffle 12211 are respectively located above the first limiting part 23 and the second limiting part 33, which can prevent the first protective door 2 and the second protective door 3 from popping up from the base; the first vertical baffle 12112 and the second vertical baffle 12212 respectively axially limit the first limiting part 23 and the second limiting part 33.

[0072] Preferably, the base 12 is provided with a first mounting groove 1201 corresponding to the first transverse baffle 12111, and the base 12 is provided with a second mounting groove 1202 corresponding to the second transverse baffle 12211. The first limiting part 23 and the second limiting part 33 can extend into the first mounting groove 1201 and the second mounting groove 1202, and the first mounting groove 1201 and the second mounting groove 1202 limit the sliding of the first limiting part 23 and the second limiting part 33. In this embodiment, the first mounting groove 1201 and the second mounting groove 1202 can guide and limit the sliding of the first protective door 2 and the second protective door 3, greatly improving reliability.

[0073] Preferably, the distance that the first limiting part 23 moves from the first position to the second position within the first mounting groove 1201 is less than the distance that the first transverse baffle 12111 extends from the first vertical baffle 12112 toward the direction close to the second vertical baffle 12212, thereby limiting the first limiting part 23 within the first mounting groove 1201; the distance that the second limiting part 33 moves from the third position to the fourth position within the second mounting groove 1202 is less than the distance that the second transverse baffle 12211 extends from the second vertical baffle 12212 toward the direction close to the first vertical baffle 12112, thereby limiting the second limiting part 33 within the second transverse baffle 12211.

[0074] like Figure 5 , 7 As shown in Figure 9, the base 12 is provided with a first guide rail beam 121, and the first protective door 2 is provided with a first guide rail groove 24 corresponding to the first guide rail beam 121, so that the first protective door 2 and the base 12 are in sliding engagement.
