Description

Technical Field

[0001] This utility model relates to the field of power socket technology, specifically to a universal live and neutral wire metal plate for German and Italian standard power sockets and a German and Italian standard power socket. Background Technology

[0002] Because German standard plugs only have two cylindrical prongs, German sockets lack a grounding hole and cannot be used with appliances that require grounding. Italian standard plugs, on the other hand, have three cylindrical prongs: one for neutral, one for live, and one for ground. Therefore, Italian sockets consist of three holes: the middle one for ground, and one for neutral and one for live. This incompatibility between German and Italian plugs forces users to carry multiple adapters or power adapters to adapt to different countries' socket standards, increasing the complexity and inconvenience of travel.

[0003] Simply integrating German and Italian standard sockets into one unit, while compatible with both Italian and German standards, results in a bulky socket that remains inconvenient to carry when traveling.

[0004] To address the issue of the large size of German and Italian standard multi-functional power sockets, the inventor conceived of sharing the neutral and live wire metal contacts for both standards. However, Italian plugs come in two sizes: 4mm × 19mm (4mm pin diameter, 19mm pin spacing) and 5mm × 26mm (5mm pin diameter, 26mm pin spacing). Similarly, German plugs come in two sizes: 4mm × 19mm (4mm pin diameter, 19mm pin spacing) and 4.8mm × 19mm (4.8mm pin diameter, 19mm pin spacing). This means that Italian plugs have different pin spacing, and German plugs have different pin diameters. If all sizes of Italian and German standard sockets were directly integrated into the existing neutral and live wire metal contacts, the existing structure would result in poor clamping and springback forces, leading to problems such as difficulty in inserting the plug or a loose connection.

[0005] Furthermore, when Italian and German standards are integrated into one socket, the resulting socket is generally quite large. If a USB charging port is added to this socket, even if the functionality of the socket is increased, the size of the socket will still increase, making it more inconvenient to carry when traveling. Utility Model Content

[0006] To address at least one of the aforementioned problems, the inventors conducted repeated experiments on the structure of the live and neutral wire metal sheet, developing a universal live and neutral wire metal sheet with superior clamping force and resilience compared to existing ones. This solves the problem that existing live and neutral wire metal sheets, due to structural limitations, are unsuitable for use with multiple plug specifications simultaneously. Therefore, according to one aspect of this utility model, a universal live and neutral wire metal sheet for German and Italian standard multi-functional power sockets is provided.

[0007] The universal live and neutral wire metal piece (which can be either a neutral or live wire metal piece) for German and Italian standard multi-functional power sockets includes a first metal piece. The first metal piece has multiple bending structures and connecting pieces that connect the bending structures in sequence. The two free ends of the first metal piece and the bending structures adjacent to the free ends respectively form a first enclosing piece and a second enclosing piece for forming a socket. Connecting pieces are provided on the side of the first enclosing piece and the second enclosing piece that is away from each other, and the two connecting pieces are connected on the side of the free end of the first metal piece that is away from the bending structure that is adjacent to it.

[0008] This application involves sequentially bending a first metal sheet along a first direction (e.g., clockwise or counterclockwise) to form a first and second enclosing sheet that can be closed to form a socket. Additionally, connecting pieces are sequentially connected via bending structures around the outer sides of the first and second enclosing sheets. Two connecting pieces are connected to the first and second enclosing sheets respectively via bending structures. The connecting pieces on the opposite sides of the first and second enclosing sheets are connected to the side of the free end of the first metal sheet opposite to its adjacent bending structure. This results in the first and second enclosing sheets having good resilience. When the socket formed by the first and second enclosing sheets has multiple spacings and accommodates different sizes of plugs at the same spacing, the socket formed by the highly resilient first and second enclosing sheets can maintain good contact with the plug after multiple insertions and removals of plugs of different specifications, without any loosening issues.

[0009] In some embodiments, the planes containing the bending directions of all the bending structures are parallel to each other. Thus, the aforementioned bending structure can be formed by continuously bending a metal sheet along a first direction (such as clockwise or counterclockwise). Moreover, since the first circumferential sheet, the connecting sheet, and the second circumferential sheet formed thereby are sequentially connected by the bending structure without any interruption, the first and second circumferential sheets are constrained by the connecting sheet and the bending structure when they undergo elastic deformation. Compared with existing neutral and live wire metal sheets, the resilience of the first and second circumferential sheets can be improved.

[0010] In some embodiments, the connecting piece includes a first piece, a second piece, and a third piece; the bending structure includes a first bending portion, a second bending portion, a third bending portion, and a fourth bending portion that respectively connect the first assembly piece, the first piece, the second piece, the third piece, and the second assembly piece (i.e., the first assembly piece and the first piece are connected through the first bending portion; the first piece and the second piece are connected through the second bending portion; the second piece and the third piece are connected through the third bending portion; the third piece and the second assembly piece are connected through the fourth bending portion); the first piece is located on the side of the first assembly piece opposite to the second assembly piece; the second piece is located on the side of the free end of the first metal piece opposite to its adjacent bending structure; the third piece is located on the side of the second assembly piece opposite to the first assembly piece.

[0011] Therefore, the first assemblies, the first sheet, the second sheet, the third sheet, and the second assemblies are connected sequentially by a bending structure without any interruption. This means that when the first and second assemblies undergo elastic deformation, they are constrained by the first sheet, the second sheet, the third sheet, and the bending structure. As a result, compared with existing neutral and live wire metal sheets, the resilience of the first and second assemblies can be improved.

[0012] In some embodiments, the distance between the sides of the first and second assemblies furthest from the free end is greater than the distance between the sides of the first and second assemblies closest to the free end. This allows the sockets at different positions formed by the first and second assemblies to accommodate pins of different diameters and have different springback capabilities to accommodate pins with various spacings and diameters.

[0013] In some embodiments, the spacing between the connecting pieces on the opposite sides of the first and second assemblies gradually decreases from the side near the free end of the first assembly to the side away from the free end of the first assembly. Since the first and second assemblies have a first opening at their ends away from their free ends, by setting the spacing between the connecting pieces on the opposite sides of the first and second assemblies to be smaller on the side away from the free end, the free ends of the first and second assemblies can still have good resilience even with the first opening. In particular, when the spacing on the side away from the free end of the first and second assemblies is greater than the spacing on the side near the free end of the first and second assemblies, setting the spacing between the connecting pieces on the opposite sides of the first and second assemblies to be smaller on the side away from the free end can also avoid the problem of potentially weakened resilience caused by the spacing on the side away from the free end of the first and second assemblies being greater than the spacing on the side near the free end.

[0014] In some embodiments, the first metal sheet further includes a mounting tab for mounting on the housing of the power socket, the mounting tab being connected to a connecting tab or bending structure on the side of the free end opposite to its adjacent bending structure. This avoids an uneven effect of the mounting tab on the resilience of the first and second assemblies.

[0015] According to another aspect of this utility model, a German-standard or Italian-standard power socket is provided.

[0016] The German and Italian standard power socket includes a neutral wire and a live wire; at least one of the neutral wire and the live wire uses the aforementioned universal neutral and live wire metal piece for German and Italian standard power sockets.

[0017] Because the first metal sheet of this application is bent sequentially along the first direction, in addition to forming a first and second enclosing sheet that can be closed to form a socket on the first metal sheet, connecting pieces are also surrounded on the outside of the first and second enclosing sheets by sequentially connected by bending structures. The two connecting pieces are respectively connected to the first and second enclosing sheets by bending structures. The connecting pieces on the opposite side of the first and second enclosing sheets are connected to the side of the free end of the first metal sheet that is opposite to its adjacent bending structure, thereby giving the first and second enclosing sheets good resilience. When the socket formed by the first and second enclosing sheets is provided with multiple spacings, and different sizes of plugs are adapted to the same spacing, the socket formed by the first and second enclosing sheets with high resilience can still maintain good contact with the plug after multiple plugging and unplugging of plugs of different specifications, and there will be no loosening problem.

[0018] In some embodiments, the German and Italian standard power socket also includes a housing and a USB charging port disposed on the housing. Thus, the plug can be charged not only by connecting to the neutral and live wires, but also by inserting into the USB charging port. That is, the German and Italian standard power socket of this application is compatible not only with appliances with ordinary plugs, but also with appliances with USB plugs, further solving the problem of the complexity and inconvenience of carrying multiple sockets when traveling.

[0019] In some embodiments, the free ends of the neutral and live wires are positioned facing each other, meaning that when installed in a German or Italian standard power socket, the distance between their free ends is minimized. Specifically, when the distance between the sides of the first and second assemblies furthest from their free ends is greater than the distance between the sides of the first and second assemblies closest to their free ends; and / or when the distance between the connecting pieces on the opposite sides of the first and second assemblies gradually decreases from the side closest to the free end of the first assembly to the side furthest from its free end, the resilience of the first and second assemblies, which form different hole spacings and accommodate different socket diameters, can adapt to their respective socket diameters and corresponding hole spacings.

[0020] In some embodiments, the German and Italian standard power socket also includes terminals and electronic components electrically connected to the USB charging port; the terminals are located on one side of the neutral and live wires; the electronic components are located on the side of the neutral and live wires opposite to the terminals. By rationally arranging the positions of the terminals, neutral wire, live wire, and electronic components electrically connected to the USB charging port, this application can achieve a multi-functional compact power socket that combines Italian, German, standard, and USB charging port specifications without increasing the overall size (e.g., 45mm × 45mm) compared to a single-function power socket (either only German standard, or only Italian standard, without a USB charging port).

[0021] In some embodiments, the German and Italian standard power socket further includes a grounding plate with a first recess for accommodating a grounding pin, and first clearance spaces on both sides of the first recess for accommodating electronic devices, and second clearance spaces for accommodating terminals. By providing the first clearance spaces for accommodating electronic devices and the second clearance spaces for accommodating terminals on the grounding plate, this application can achieve a multi-functional compact power socket that combines Italian, German, standard sockets, and USB charging ports without increasing the overall size compared to a single-function power socket.

[0022] In some embodiments, the housing includes a bottom shell, on which are provided a first receiving space, a second receiving space, a third receiving space, a terminal receiving space, and a fourth receiving space for accommodating the neutral wire, the live wire, the ground wire, the terminal block, and the electronic components, respectively. Thus, the dedicated receiving spaces ensure the stability of the installation of the neutral wire, the ground wire, the live wire, the terminal block, and the electronic components, preventing mutual interference during use.

[0023] In some embodiments, the housing also includes a top shell detachably connected to the bottom shell; protective doors are provided between the neutral and live wire contacts and the top shell. This provides an anti-misinsertion function. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0038] Figures 1 to 3 The diagram schematically shows a universal live and neutral wire metal strip for a German or Italian standard power socket according to one embodiment of the present invention.

[0039] like Figures 1 to 3 As shown, the universal live and neutral wire metal sheet for German and Italian standard power sockets includes a first metal sheet 20. The first metal sheet 20 is bent sequentially along a first direction to form a first enclosed sheet 23, a first sheet body 221, a second sheet body 222, a third sheet body 223, and a second enclosed sheet 24, which are connected sequentially by a first bending portion 211, a second bending portion 212, a third bending portion 213, and a fourth bending portion 214. That is, one end of the first enclosed sheet 23 and the first sheet body 221 are connected by the first bending portion. 211 connection; the opposite end of the first piece 221 is connected to the second piece 222 via the second bend 212; the second piece 222 is connected to the third piece 223 via the third bend 213; the third piece 223 is connected to the second enclosing piece 24 via the fourth bend 214; the ends of the first enclosing piece 23 and the second enclosing piece 24 away from the bends they are connected to are free ends 26; the first enclosing piece 23 and the second enclosing piece 24 together form a socket 28 for inserting Italian and German standard pins. Therefore, a first sheet 221 is provided on the side of the first sheath 23 facing away from the second sheath 24; a third sheet 223 is provided on the side of the second sheath 24 facing away from the first sheath 23; and a second sheet 222 is provided on the side of the free end 26 of the first sheath 23 and the second sheath 24 facing away from the bend (first bend 211 and fourth bend 214) connecting the first sheath 23 and the second sheath 24, that is, the first sheath 23 and the second sheath 24 are connected by a bend. The periphery of the sheet 24 is not only surrounded by the first sheet 221, the second sheet 222, and the third sheet 223 connected in sequence; but the first sheet 23 and the second sheet 24 are also connected to the first sheet 221 and the third sheet 223 respectively through the first bending portion 211 and the fourth bending portion 214; at the same time, the first sheet 221 is connected to the second sheet 222 through the second bending portion 212, and the second sheet 222 is connected to the third sheet 223 through the third bending portion 213.

[0040] In this application, the socket 28 for inserting pins, formed by the first surrounding sheet 23 and the second surrounding sheet 24, can be implemented using methods commonly found in the prior art. For example, the first surrounding sheet 23 and the second surrounding sheet 24 can be integrally formed or machined with arc shapes at positions corresponding to the socket 28, so that the socket 28 is formed by the arc shapes at corresponding positions of the two surrounding sheets. The number of sockets 28 can be set according to the required number of arc shapes, and German standard sockets 28, Italian standard sockets 28, sockets 28 conforming to 10A, and sockets 28 conforming to 16A can be set as needed. This application does not limit the specific structure of the socket 28 formed by the first surrounding sheet 23 and the second surrounding sheet 24.

[0041] In some embodiments, such as Figure 3 As shown, the first bend 211, the second bend 212, the third bend 213 and the fourth bend 214 constitute the bend structure 21 of an embodiment of this application.

[0042] In some embodiments, such as Figure 3 As shown, the first piece 221, the second piece 222, and the third piece 223 constitute the connecting piece 22 of one embodiment of this application.

[0043] In some embodiments, such as Figure 3 As shown, the first metal sheet 20 has multiple bent portions and connecting pieces 22 that connect the bent portions in sequence.

[0044] This application involves sequentially bending the first metal sheet 20 along a first direction (e.g., clockwise or counterclockwise). In addition to forming a first surrounding sheet 23 and a second surrounding sheet 24 on the first metal sheet 20 that can enclose the insertion hole 28, a connecting piece 22 is also formed around the outside of the first surrounding sheet 23 and the second surrounding sheet 24, sequentially connected by a bending structure 21 and connected to the first surrounding sheet 23 and the second surrounding sheet 24. Through the arrangement of the bending structure 21 and the connecting piece 22, and the absence of a spacer in the bending direction of the first metal sheet 20... The first and second assemblies 23 and 24 have good resilience and large clamping force. When the socket 28 formed by the first and second assemblies 23 and 24 is set with multiple spacings and different sizes of plugs are adapted to the same spacing, the socket 28 formed by the first and second assemblies 23 and 24 with high resilience can still maintain good contact with the plug after multiple plugging and unplugging of plugs of different specifications, and there will be no loosening problem. The number of plugging and unplugging cycles reaches a higher level, passing the 5000-cycle life test.

[0045] In some preferred embodiments, such as Figure 3 As shown, the planes containing the bending directions of all the bent structures 21 are parallel to each other. Thus, by passing a metal sheet along a first direction (e.g., clockwise or counterclockwise, as shown in the diagram)... Figure 3As shown by the arrow, continuous bending can form the aforementioned bending structure 21. Moreover, since the first circumferential sheet 23, the connecting sheet 22, and the second circumferential sheet 24 formed thereby are sequentially connected by the bending structure 21 without any interruption, the first circumferential sheet 23 and the second circumferential sheet 24 will be constrained by the connecting sheet 22 and the bending structure 21 when they undergo elastic deformation. Therefore, compared with the existing neutral and live wire metal sheets, the resilience of the first circumferential sheet 23 and the second circumferential sheet 24 can be improved.

[0046] In some preferred embodiments, such as Figure 3 As shown, the distance L1 between the side of the first enclosing piece 23 and the second enclosing piece 24 away from the free end 26 (that is, the distance between the end of the first enclosing piece 23 near the first bend 211 and the end of the second enclosing piece 24 near the fourth bend 214) is greater than the distance L2 between the side of the first enclosing piece 23 and the second enclosing piece 24 near the free end 26, i.e., L1 > L2, so that the sockets 28 at different positions formed by the first enclosing piece 23 and the second enclosing piece 24 can be adapted to pins of different diameters and have different springback capabilities to accommodate pins with various spacings and diameters.

[0047] In some preferred embodiments, such as Figure 3 As shown, the distance between the connecting pieces 22 on the opposite sides of the first and second assemblies 23 and 24 gradually decreases from the side near the free end 26 of the first assembly 23 to the side away from the free end 26 of the first assembly 23; that is, the distance L3 between the first piece 221 and the third piece 223 near the free end 26 is greater than the distance L4 between the end of the first piece 221 near the first bend 211 and the end of the third piece 223 near the fourth bend 214, i.e., L3 > L4. Since the first assembly 23 and the second assembly 24 have a first opening 27 at the end away from their free end 26, by setting the distance between the first sheet 221 and the second sheet 222 to L3 > L4, the free end 26 of the first assembly 23 and the second assembly 24 can still have good resilience even with the first opening 27. In particular, when the distance between the first assembly 23 and the second assembly 24 is also set to L1 > L2, the problem that the resilience at the end away from the free end 26 of the first assembly 23 and the second assembly 24 may be weakened due to the distance L1 > L2 is also avoided.

[0048] In some preferred embodiments, such as Figures 1 to 3As shown, the first metal sheet 20 also includes a mounting piece 25 for mounting on the housing 40 of the power socket, and the mounting piece 25 is connected to the second sheet body 222. Since the mounting piece 25 is not directly connected to the first assembly sheet 23 and the second assembly sheet 24, uneven influence of the mounting piece 25 on the rebound force of the first assembly sheet 23 and the second assembly sheet 24 can be avoided. In this application, the mounting piece 25 can adopt a structure commonly used in the prior art, and this application does not limit the specific structure of the mounting piece 25.

[0049] In some embodiments, the mounting piece 25 is integrally formed with the second piece 222.

[0050] As another embodiment of the universal live and neutral wire metal sheet for German and Italian standard power sockets, the main difference between this embodiment and the previous embodiment is that the first metal sheet 20 in this embodiment does not include the second sheet 222, the second bend 212, and the third bend 213. Instead, there is a fifth bend, which connects the first sheet 221 and the third sheet 223. The fifth bend is located at the free end 26 of the first and second sheets 23, away from the first sheet 23 and the second sheet 24. One side of the bent portion (first bent portion 211 and fourth bent portion 214) connecting the two surrounding sheets 24, that is, the periphery of the first surrounding sheet 23 and the second surrounding sheet 24, not only surrounds the first sheet 221, the fifth bent portion and the third sheet 223 connected in sequence; but the first surrounding sheet 23 and the second surrounding sheet 24 are also connected to the first sheet 221 and the third sheet 223 respectively through the first bent portion 211 and the fourth bent portion 214; at the same time, the first sheet 221 is connected to the third sheet 223 through the fifth bent portion. The universal neutral and live wire metal sheet of this embodiment achieves the same effect as the universal neutral and live wire metal sheet of the previous embodiment. Preferably, the first metal sheet 20 further includes a mounting piece 25 for mounting on the housing 40 of the power socket, and the mounting piece 25 is connected to the fifth bent portion. Since the mounting piece 25 is not directly connected to the first assembly piece 23 and the second assembly piece 24, the uneven effect of the mounting piece 25 on the rebound force of the first assembly piece 23 and the second assembly piece 24 can be avoided.

[0051] Figures 4 to 9 The diagram schematically illustrates a German or Italian standard power socket according to one embodiment of the present invention.

[0052] like Figure 6 and Figure 7 As shown, the German and Italian standard power socket includes a neutral wire piece 31 and a live wire piece 32; at least one of the neutral wire piece 31 and the live wire piece 32 adopts the aforementioned universal neutral and live wire metal piece for German and Italian standard power sockets.

[0053] Therefore, the first and second enclosing plates 23 and 24 of the neutral wire piece 31 and the live wire piece 32, which use universal neutral and live wire metal pieces, have good resilience. When the socket 28 formed by the first and second enclosing plates 23 and 24 is provided with multiple spacings, and different sizes of plugs are adapted to the same spacing, the socket 28 formed by the first and second enclosing plates 23 and 24, which have high resilience, can still maintain good contact with the plug after plugging and unplugging different specifications of plugs multiple times, and there will be no loosening problem.

[0054] In some preferred embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the German and Italian standard power socket also includes a housing 40 and a USB charging port 34 disposed on the housing 40. The neutral wire piece 31 is electrically connected to the neutral wire of the power supply via a neutral wire terminal 351, and the live wire piece 32 is electrically connected to the live wire of the power supply via a live wire terminal 352. In some embodiments, the USB charging port can be a conventional USB charging port such as a Type-A interface, a Type-B interface, or a Type-C interface. This allows the German and Italian standard power socket of this application to be compatible not only with appliances with ordinary plugs but also with appliances having USB plugs.

[0055] In some embodiments, such as Figure 6 and Figure 7 As shown, the German and Italian standard power socket also includes an electronic device 36 electrically connected to the USB charging port 34. The electronic device 36 includes an electronic capacitor 362 and a transformer 361 for providing voltage conversion for the USB charging port; both the electronic capacitor 362 and the transformer 361 are electrically connected to the USB charging port 34.

[0056] In some embodiments, such as Figure 6 and Figure 7 As shown, the German and Italian standard power socket also includes a terminal block 35, which includes a neutral terminal block 351, a live terminal block 352, and a ground terminal block 353.

[0057] In some preferred embodiments, such as Figure 6 and Figure 7 As shown, the terminal block 35 is located on one side of the neutral wire piece 31 and the live wire piece 32; the electronic component 36 is located on the side of the neutral wire piece 31 and the live wire piece 32 opposite to the terminal block 35, so as to obtain a multi-functional compact power socket that combines Italian standard, German standard, ordinary socket and USB charging port without increasing the size (e.g. 45mm×45mm) compared with a single-function power socket.

[0058] In some preferred embodiments, such as Figure 6As shown, the free ends 26 of the neutral wire piece 31 and the live wire piece 32 are arranged facing each other. In particular, when L3 > L4; and / or when L1 > L2, the elastic force of the first and second assemblies 23 and the second assemblies 24, which are enclosed with different hole spacings and adapted to different hole diameters of the insertion holes 28, can be adapted to their adapted hole diameters and corresponding hole spacings.

[0059] In some embodiments, such as Figures 6 to 8 As shown, the German and Italian standard power socket also includes a grounding piece 33. Preferably, the grounding piece 33 has a first groove 331 for placing the grounding pin by bending, and a first clearance space 332 on both sides of the first groove 331 for avoiding electronic components 36, and a second clearance space 333 for avoiding terminals 35. This results in a multi-functional compact power socket that combines Italian, German, standard, and USB charging ports without increasing the overall size compared to a single-function power socket. The first clearance space 332 and the second clearance space 333 are formed, for example, by bending the grounding piece 33 at 90° on both sides forming the first groove 331, to create a well-organized clearance space. This facilitates the neat arrangement of the various components (neutral piece 31, live piece 32, ground piece 33, electronic components 36, terminals 35, etc.) of the German and Italian standard power socket, ultimately achieving the compactness of the German and Italian standard power socket structure.

[0060] In some preferred embodiments, such as Figure 6 and Figure 9 As shown, the housing 40 includes a bottom shell 41, on which are integrally formed or machined a first receiving space 411 for accommodating the neutral wire 31, a second receiving space 412 for accommodating the live wire 32, a third receiving space 413 for accommodating the ground wire 33, a terminal receiving space 415 for accommodating the terminal block 35, and a fourth receiving space 414 for accommodating the electronic device 36. The dedicated receiving spaces ensure the stability of the installation of the neutral wire 31, ground wire 33, live wire 32, terminal block 35, and electronic device 36, preventing mutual interference during use. Preferably, the spaces within the terminal receiving space 415 that accommodate the neutral terminal 351, live terminal 352, and ground terminal 353 are also separated to prevent mutual interference between the terminals.

[0061] In some preferred embodiments, such as Figure 7As shown, the housing 40 also includes a top housing 42 that is detachably connected to the bottom housing 41; a protective door 37 is provided between the neutral wire piece 31 and the live wire piece 32 and the top housing 42. This enables the function of preventing misinsertion. The protective door 37 can be installed in a manner commonly used in the prior art. For example, a mounting plate 43 is fixedly installed on the bottom shell 41 or the top shell 42. The protective door 37 can be movably installed on the mounting plate 43 in a direction perpendicular to the insertion of the plug. Under the action of the elastic element, the protective door 37 blocks the socket 28 of the neutral wire piece 31 and the live wire piece 32. The surface of the protective door 37 facing away from the neutral wire piece 31 and the live wire piece 32 is provided with an inclined surface 371. When the plug abuts against the inclined surface 371, the protective door 37 moves to expose the socket 28 of the neutral wire piece 31 and the live wire piece 32 and compresses the elastic element. When the plug is unplugged, under the elastic force of the elastic element, the protective door 37 moves to the position that blocks the socket 28 of the neutral wire piece 31 and the live wire piece 32. The protective door 37 can be movably mounted on the mounting plate 43 by providing a guide rail 431 on the mounting plate 43 and a slider 372 adapted to the guide rail 431 on the protective door 37. In some embodiments, the mounting plate 43 may also be integrally formed on the bottom shell 41 or the top shell 42. The protective door 37 may also be mounted in other ways commonly used in the prior art, and this application does not limit the specific mounting method of the protective door 37.

[0062] In some embodiments, such as Figure 4 As shown, the top shell 42 has an integrally formed or machined neutral wire hole 421, live wire hole 422 and ground wire hole 423 for the pins to pass through.

[0063] In some preferred embodiments, to avoid contact between the electronic device 36 and the ground plane 33, such as Figure 7 As shown, a baffle 44 is also provided between the electronic device 36 and the ground plate 33 to prevent the electronic device 36 and the ground plate 33 from interfering with each other.

[0064] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0065] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
