[0027] The implementation and use of the embodiments will now be discussed in detail. It should be appreciated that the specific embodiments discussed are merely illustrative of specific ways in which the present application can be implemented and used, and are not limiting of the scope of the present application. In describing the various components of the embodiments, relative terms such as upper, lower, left, right, etc. are used to describe the orientation of the components. These terms are relative and are made with respect to the orientation of the components as shown in the figures. If the orientation of the components in the figures is changed, the relative terms will change accordingly.

[0028] According to the standards of different countries, the size of a wall power socket and the size of the space reserved for the socket in a wall are fixed. For a single wall power socket, the size of the space inside the corresponding cavity can be 90 mm in height, 90 mm in width, and 32 mm in depth. Generally, only one power interface for a power plug to be inserted can be provided on such a socket. With the rise of, for example, mobile phones and notebook computers, a USB charging interface can be directly added to the original power socket, so that a power adapter is not needed.

[0029] However, due to the space limitation inside the current single wall power socket, the size of the USB charging circuit board inside the socket is small, so that the number of USB charging interfaces is not more than two and the charging power is small, generally not more than 18 W.

[0030] To solve the above problems, one embodiment of the present application provides a wall socket, comprising: a panel, a USB circuit board, a live metal piece, a neutral metal piece, a ground metal piece, and a base. The USB circuit board, the live metal piece, and the neutral metal piece are arranged in a space between the panel and the base. An upper part of the USB circuit board is provided with a USB interface, and a lower part of the USB circuit board has a width smaller than that of the upper part. The live metal piece is arranged below the lower part of the USB circuit board. The ground metal piece comprises a ground pin, the neutral metal piece comprises a neutral pin, and the live metal piece comprises a live pin. The ground pin is arranged below the upper part of the USB circuit board.

[0031] Figure 1 A surface view of a wall socket (hereinafter referred to as "socket" or "power socket") 100 of one embodiment of the present application is shown. Figure 1 The power socket 100 comprises one power interface 3, three USB interfaces including two Type-A interfaces 21, 23 and one Type-C interface 22, and a switch button 5 for controlling the connection and disconnection of the current of the power interface 3. The USB interfaces of the socket are always powered on after being powered on, and are not controlled by the switch button. The panel of the socket 100 is provided with a plurality of through holes to accommodate the power interface, the plurality of USB interfaces, and the switch button.

[0032] In the example of Figure 1 , the three USB interfaces are arranged in the upper part of the socket, and the power interface and the switch button are arranged in the lower part of the socket. In addition, the switch button is arranged to the right of the power interface. Specifically, the switch button is arranged to the right of the live pin in the power interface. It can be understood that the types and numbers of the USB interfaces are not limited to Figure 1 the example, but can also be other combinations, such as a USB interface comprising one Type-A interface and two Type-C interfaces, or three Type-C interfaces, etc.

[0033] Figure 2 A perspective exploded view of the wall power socket 100 of Figure 1 is shown. The wall power socket 100 comprises a panel 1, a USB circuit board 2, a live metal piece 31, a neutral metal piece 32, a ground metal piece 33, and a base 4.

[0034] The panel 1 is arranged on the surface of the socket 100, and the panel 1 is provided with through holes corresponding to the USB interfaces, the power interface, and the switch. The base 4 is arranged on the back of the socket 100. The space between the panel 1 and the base 4 can accommodate the USB circuit board 2 and the live metal piece 31 and the neutral metal piece 32.

[0035] In some examples, the socket further comprises an intermediate panel arranged inside the panel, and a surface of the intermediate panel is provided with a recess for placing a heat dissipation plate. For example, the socket 100 is provided with an intermediate panel 6 between the panel 1 and the USB circuit board 2. Similar to the panel 1, the intermediate panel 6 is provided with through holes corresponding to the USB interfaces, the power interface and the switch, and the through holes are matched with the through holes on the panel 1 in position. The intermediate panel 6 is arranged inside the panel 1. The intermediate panel 6 and the base 4 can be fixed by rivets 63. The panel 1 and the intermediate panel 6 can be fixed by rivets or by clamping. Compared with rivet connection, the clamping method is more convenient to disassemble. When the socket 100 needs to be installed on a wall of different color, the panel 1 of different color can be replaced to match the color of the wall.

[0036] The surface of the intermediate panel 6 is provided with a recess 61 which avoids the positions of the power interface 3, the USB interfaces 21, 22, 23 and the switch button 5. In addition, the recess 61 can be provided with a heat dissipation plate 62. The recess 61 and the heat dissipation plate 62 are matched in shape. Figure 1 In some examples, the recess 61 is T-shaped as a whole, and the heat dissipation plate 62 is also T-shaped as a whole. In addition, the heat dissipation plate 62 is provided with a rectangular through hole to avoid the positions of the USB interfaces 21, 22, 23. In some examples, the heat dissipation plate can include one or more of a graphene heat dissipation plate, a graphite heat dissipation plate and a metal heat dissipation plate.

[0037] The USB circuit board 2 is provided with USB interfaces 21, 22, 23 and other components. The positions of the USB interfaces 21, 22, 23 are consistent with the positions of the corresponding through holes on the panel 1 and the intermediate panel 6. The USB circuit board 2 is T-shaped as a whole, including an upper part and a lower part. The upper part of the USB circuit board 2 is provided with the USB interfaces 21, 22, 23, and the lower part can be provided with other components. The width of the upper part is greater than the width of the lower part. The width of the upper part is close to the width of the inside of the base 4. The left and right sides of the lower part of the USB circuit board 2 form two L-shaped notches with the upper part. The width of the lower part is smaller, which can avoid the positions of the metal parts in the power interface. It can be understood that the "left" and "right" of the present application are based on the perspective of the front of the socket and facing the socket. The "front", "rear" or "back" of the present application are based on the perspective of the socket in the installed state.

[0038] Figure 3 A schematic view of the USB circuit board 2 and the metal parts in the base 4 of the wall socket 100 is shown. Figure 4 A perspective exploded view of the USB circuit board 2, the live metal part 31, the neutral metal part 32 and the base 4 of the wall socket 100 is shown. Figure 5 A disassembled schematic view of the metal parts of the wall socket 100 is shown. Figure 6A back view of the wall socket 100 is shown.

[0039] Figures 3-4 The relative positions of the fire wire metal piece 31, the zero wire metal piece 32 and the USB charging board 2 in the base 4 are shown. A partition is provided in the interior of the base 4 and below the USB charging board 2 for separating the metal pieces from the USB charging. The USB circuit board 2 occupies about half of the area of the bottom plane of the base 4.

[0040] The fire wire metal piece 31 and the zero wire metal piece 32 are located below the USB circuit board 2. Specifically, the fire wire metal piece 31 is located below the lower part of the USB circuit board 2. The zero wire metal piece 32 is substantially parallel to the fire wire metal piece 31, and the zero wire metal piece 32 is located below the upper part of the USB circuit board 2, i.e. the zero wire metal piece 32 is located at the lower left position of the USB circuit board 2.

[0041] The fire wire metal piece 31 includes a fire wire pin 311, the zero wire metal piece 32 includes a zero wire pin 321, and the ground wire metal piece 33 includes a ground wire pin 331. The fire wire pin 311, the zero wire pin 321 and the ground wire pin 331 are all in the structure of a spring sheet, which can be inserted and pulled by the plug rod of an external electrical appliance. The ground wire pin 331 is located below the upper part of the USB circuit board. In addition, the ground wire pin 331 can be located at the left of the lower part of the USB circuit board, i.e. the ground wire pin 331 is located at the notch on the left side of the USB circuit board. The position of the ground wire pin 331 is also adjacent to the edge of the lower left part of the USB circuit board.

[0042] In the socket 100, the USB interface is located above the socket, the power interface is located below the socket, and the edge of the lower part of the USB circuit board avoids the positions of the pins in the power interface. This structure can increase the area of the USB circuit board, so that it occupies more than half of the area of the bottom plane of the base. The increase in the area of the USB circuit board can allow more components to be provided thereon, so that the charging power of the USB circuit board can be increased to 21W or even 30W. When charging an electronic device such as a mobile phone using the socket 100, the charging efficiency is higher.

[0043] From Figure 2 , Figure 4 It can be seen that the fire wire metal piece 31 includes a first fire wire metal sub-piece 31a and a second fire wire metal sub-piece 31b, which are arranged in cross parallel. The fire wire pin 311 is provided on the first fire wire metal sub-piece 31a.

[0044] Referring to Figure 5The first live metal sub-piece 31a includes the live pin 311, and further includes a first live metal sheet 312 and a fixed contact sheet 313. The first live metal sub-piece 31a is generally in the shape of an inverted U, with the live pin 311 at one end thereof, and the first live metal sheet 312 at the upper right of the live pin. The first live metal sheet 312 is in the shape of an inverted L, with the metal sheet at the left portion thereof extending horizontally, and the metal sheet at the right portion thereof extending vertically. In addition, the planes in which the left and right portions of the first live metal sheet 312 lie are perpendicular to the plane in which the faceplate 1 lies. Unlike the example in which the plane in which the first live metal sheet lies is parallel to the plane in which the faceplate 1 lies, the first live metal sheet 312 can save more space for accommodating a USB circuit board of a larger area.

[0045] In the first live metal sub-piece 31a, the live pin 311 is at one end of the first live metal sheet 312, and the fixed contact sheet 313 is at the other end of the first live metal sheet 312. The live pin 311, the first live metal sheet 312, and the fixed contact sheet 313 can be integrally formed. The fixed contact sheet 313 extends to the right at the end of the first live metal sheet 312.

[0046] The first live metal sub-piece 31a is provided with the live pin 311. The second live metal sub-piece 31b is connected to the live terminal 71 to connect to the external live wire. The connection between the two live metal sub-pieces is controlled by the switch button 5.

[0047] The second live metal sub-piece 31b includes a live connecting sheet 314, a second live metal sheet 315, and a support sheet 316. The second live metal sub-piece 31b can be integrally formed. The live connecting sheet 314 is connected to the live terminal 71 to connect to the external live wire. The live connecting sheet 314 is at one end of the second live metal sheet 315, and the support sheet 316 is at the other end of the second live metal sheet 315. The second live metal sheet 315 includes left and right portions, with the metal sheet at the left portion extending horizontally, and the metal sheet at the right portion extending vertically. In addition, the plane in which the second live metal sheet 315 lies is parallel to the plane in which the faceplate 1 lies.

[0048] The support sheet 316 is used to support the movable contact sheet 51. The movable contact sheet 51 is used to connect to or disconnect from the fixed contact sheet 313 by being actuated by the switch button 5, thereby controlling the connection to the live pin 311.

[0049] The second live metal sub-piece 31b is smaller in size than the first live metal sub-piece 31a. As shown in FIG. 2, the second live metal sub-piece 31b is arranged in cross parallel with the first live metal sub-piece 31a. In such a structure, the top of the live metal piece 31 forms a flat area to fit the edge of the lower portion of the USB circuit board 2. Figure 4

[0050] ​The neutral wire metal component 32 includes a neutral wire pin 321, a neutral wire metal piece 322, and a neutral wire connecting piece 323. The neutral wire metal component 32 is integrally formed. One end of the neutral wire metal component 32 is provided with the neutral wire pin 321. The metal piece extending from the right side of the upper half of the neutral wire pin 321 is the neutral wire connecting piece 323. The neutral wire connecting piece 323 extends vertically from the right side of the neutral wire pin 321, and the plane of the neutral wire connecting piece 323 is perpendicular to the plane of the panel 1. The neutral wire connecting piece 323 is connected to the neutral wire terminal 72 for external neutral wire access.

[0051] The neutral wire metal strip 322 comprises a multi-segmented sheet structure. The neutral wire metal strip 322 consists of left and right parts. The left part of the neutral wire metal strip 322 has a bent shape, such as a flipped L-shape, and its lower end connects to the neutral wire pin 321. The plane containing the left part of the neutral wire metal strip 322 is parallel to the plane containing the panel 1. The right part of the neutral wire metal strip 322 has a stepped structure and is perpendicular to the plane containing the panel 1. The shape of the right part of the neutral wire metal strip 322 matches the lower edge of the USB circuit board 2 to provide more space for the USB circuit board 2.

[0052] The grounding metal component 33 includes a grounding pin 331, a grounding metal piece 332, and two grounding connecting pieces 333 and 334. A first grounding connecting piece 333 and a second grounding connecting piece 334 are located below the grounding pin 331. These two grounding connecting pieces are located at the lower left edge of the grounding metal component 33 and are positioned at a right angle to each other. The first grounding connecting piece 333 and the second grounding connecting piece 334 are respectively connected to a first grounding terminal 73 and a second grounding terminal 74 to connect to an external grounding wire. The grounding metal piece 332 and the two grounding connecting pieces 333 and 334 can be integrally formed and can be riveted together with the grounding pin 331.

[0053] like Figure 3 , Figures 4-6 As shown, the ground wire pin 331 of the grounding metal component 33 passes through the hole in the base 4, and the remaining components are located on the back of the base 4. The base 4 includes multiple through holes, namely a live wire connection port 41, a neutral wire connection port 42, and two ground wire connection ports 43 and 44 (first ground wire connection port and second ground wire connection port). These connection ports are aligned with the through holes of the corresponding terminals for external cable access.

[0054] The upper part of the base 4 may be provided with multiple heat dissipation holes 45, and some of the heat generated by the USB circuit board 2 can be dissipated to the outside of the base 4 through the heat dissipation holes 45.

[0055] In some implementations, the USB circuit board draws power through soldering. Specifically, the contacts on the USB circuit board are connected to the live and neutral wires via soldered wires. This method requires manual soldering of the wires when installing the socket, which is not conducive to automated production.

[0056] In some examples, power to the USB circuit board can be achieved through a locking mechanism. For example, in Figures 4-5 In the example, the lower part of the USB circuit board 2 has two holes 24 and 25 (first hole and second hole). Two holes 3221 and 3151 (third hole and fourth hole) are provided at corresponding positions on the neutral wire metal piece 32 and the live wire metal piece 31. Specifically, an upwardly protruding metal piece is provided at the right end of the neutral wire metal piece 322, and a hole 3221 is provided on this metal piece. A hole 3151 is provided at the top of the metal piece on the right side of the second live wire metal piece 315. Correspondingly, two screw posts 46 and 47 (first screw post and second screw post) are provided on the base 4. The socket 100 may include two screws 26 and 27 (first screw and second screw), which can pass through the USB circuit board and the metal pieces and be fixed to the base, so that the USB circuit board can draw power by being tightly fixed to the connecting metal pieces. Specifically, screw 26 passes through hole 24 and hole 3221 in sequence and is finally inserted into screw post 46, and screw 27 passes through hole 25 and hole 3151 in sequence and is finally inserted into screw post 47. This not only secures the USB circuit board but also connects it to the neutral and live wires to draw power from them.

[0057] In some examples, power to the USB circuit board can be achieved via power pins. The back of the USB circuit board 2 has a neutral power pin and a live power pin. The neutral power pin can be used to contact the neutral metal part 32 when pressed, and the live power pin 29 can be used to contact the live metal part 31 when pressed.

[0058] For example, Figure 7 An example diagram illustrating the power supply method of the USB circuit board in one embodiment of this application is shown. Figure 7 As shown, the lower part of the circuit board 2 has a neutral power pin 28 and a live power pin 29 on its back. Specifically, the right end of the neutral metal piece 322 has an upwardly protruding metal piece 3222, and the top of the metal piece on the right side of the second live metal piece 315 has a metal piece 3152. Springs are installed inside the neutral power pin 28 and the live power pin 29. When the USB circuit board 2 is installed in the base 4, the springs are compressed, and the neutral power pin 28 and the live power pin 29 press into contact with the metal pieces 3222 and 3152 respectively, thereby enabling the USB circuit board to draw power.

[0059] In some examples, the socket 100 further comprises a misplug prevention device 80. The misplug prevention device 80 is provided with a blocking piece 81. The front side of the misplug prevention device 80 is provided with an elastic component 81. The elastic component 81 can be a spring.
