[0039] Combination Figures 1 to 7 The wall-mounted intelligent metering socket of this utility model will be further described.

[0040] A wall-mounted smart metering socket, characterized in that it includes a socket housing and a metering circuit system.

[0041] The socket housing includes a panel 4, an isolation bracket 2, a mounting box 1, and a middle cover assembly 3. The panel 4 is mounted on the connecting edge 11 at the opening of the mounting box 1 via a snap-fit ​​structure. It has an external insertion hole 41 and an external display window 42. The external display window 42 contains a display module 6, which includes a display screen 62 and buttons 63, allowing operators to directly observe and operate the device. The middle cover assembly 3 is snap-fitted onto the opening of the mounting box 1 and located behind the panel 4. It has an internal insertion hole 31 corresponding to the external insertion hole 41 and an internal display window 35 corresponding to the external display window 42. A insertion hole protection structure 32 is located inside the middle cover assembly 3, which elastically blocks the internal insertion hole 31. The isolation bracket 2 is located inside the mounting box 1 and has a high-voltage area 22 and a low-voltage area. The metering circuit system includes a control module 9 and a socket circuit module 5, a wireless communication module 7, and a temperature detection element 10 electrically connected to the control module 9. The display module 6 is also electrically connected to the control module 9. The socket circuit module 5 is located in the high-voltage area 22, and the contact copper piece 51 in the socket circuit module 5 corresponds to the inner socket 31. The control module 9, the wireless communication module 7, the display module 6, and the temperature detection element 10 are all located in the low-voltage area.

[0042] In the metering circuit system, the socket circuit module 5 includes a socket PCB board 52 and multiple sets of contact copper pieces 51 disposed on the socket PCB board 52. The multiple sets of contact copper pieces 51 form a set of three-prong sockets and a set of two-prong sockets on the socket PCB board 52. In actual use, the specific number of sockets on the socket PCB board 52 can be set according to actual usage requirements.

[0043] The control module 9 includes a main control board 91 and a Cortex-M4 main control chip embedded on the main control board. The main control chip is electrically connected to a power acquisition module, which is used to acquire the electrical parameters flowing through the socket line module 5 and then display them through the display module 6.

[0044] The wireless communication module 7 is a Wi-Fi / Bluetooth dual-mode communication module. This wireless communication module 7 is connected to the control module 9 through the 485 to TTL module 8, so that the control module 9 can wirelessly access the home system or mobile app to wirelessly transmit various electrical parameter information.

[0045] The temperature sensing element 10 is a thermistor, used to collect the temperature in the socket and transmit the temperature to the control module 9, which is then displayed by the display module 6. When the temperature is too high, the control module 9 can issue an abnormal alarm signal, which is displayed by the display module 6 or a mobile terminal.

[0046] In the socket housing structure, the isolation bracket 2 includes a mounting plate 21, and a rearwardly extending positioning support wall 28 is provided at the corner of the rear surface of the mounting plate 21. The bottom of the positioning support wall 28 is supported on the inner bottom of the mounting box 1. The edge structure shape of the mounting plate 21 is adapted to the internal space of the mounting box 1 to ensure the stability of the isolation bracket 2 in the mounting box 1.

[0047] The front surface of the mounting plate 21 has a forward-extending, L-shaped isolation wall 24. The low-voltage area is divided into a front low-voltage area 231 and a rear low-voltage area 232. The front low-voltage area 231 is the area inside the isolation wall 24, corresponding to the lower right position of the mounting plate 21. The rear low-voltage area 232 is the area on the rear surface of the mounting plate 21. The high-voltage area 22 is the area on the front surface of the mounting plate 21 corresponding to the outer side of the isolation wall 24. Through the isolation wall 24 and the mounting plate 21 body, the high-voltage and low-voltage components in the metering circuit system can be installed separately, avoiding interference between them and improving safety.

[0048] Specifically, a forward-extending mounting bracket 27 is formed on the mounting plate 21 corresponding to the inner side of the isolation wall 24. The mounting bracket 27 is located below the front low-voltage area 231. The upper and lower edges of the display module 6 are simultaneously mounted on the top of the mounting bracket 27 and the top of the isolation wall 24.

[0049] The mounting bracket 27 has a lower positioning groove 271 at its front end and the isolation wall 24 has an upper positioning groove 241 at its front end. The upper and lower ends of the PCB board 61 in the display module 6, which is used to install the display screen 62 and the button 63, are respectively positioned in the upper positioning groove 241 and the lower positioning groove 271. This ensures the stable installation of the display module and isolates the display module from the mounting plate 21, making it easier for other components to be installed in the space between the display module and the mounting plate 21.

[0050] The front low-voltage area 231 has mounting slots that extend forward and backward for inserting PCB boards perpendicular to the mounting plate 21. The PCB boards are installed perpendicular to the mounting plate 21, which makes better use of the space in the front low-voltage area 231, facilitates the installation of various components, and avoids mutual interference.

[0051] The mounting slot is divided into a first slot and a second slot. The first slot consists of two first limiting strips 261 formed on the inner sidewall of the isolation enclosure 24 and a first elastic locking foot 262 formed on the mounting plate 21. The two first limiting strips 261 are distributed vertically, and the first elastic locking foot 262 is located on the right side of the two first limiting strips 261, forming a gap between them for inserting the PCB board, which is the first slot. This first slot is located in the left area of ​​the front low-voltage zone 231, for inserting the PCB board 81 of the 485 to TTL module 8, and is secured by the barb on the front end of the first elastic locking foot 262.

[0052] The second slot is formed by the cooperation of a second limiting strip 263 formed on the mounting plate 21, a notch 265 formed on the mounting bracket 27, and a second elastic locking foot 264 formed on the mounting plate. Similarly, the second elastic locking foot 264 is located to the right of the second limiting strip 263 and the notch 265, forming a gap between them for the insertion of the PCB board, i.e., the second slot. This second slot is located in the right area of ​​the front low voltage zone 231, for the insertion of the PCB board 71 in the wireless communication module 7, and is secured by the barb on the front end of the second elastic locking foot 264.

[0053] The mounting plate 21 has a central support strip 252 and a corner support block 251 at the position corresponding to the high-voltage area 22. The corner support block 251 has a forward-extending positioning post 253. The side wall of the mounting plate 21 corresponding to the high-voltage area 22 has a third elastic locking foot 254 that secures the socket circuit module 5 to the support strip 252 and the support block 251. When the PCB board 52 in the socket circuit module 5 is installed in the high-voltage area 22, the back of the PCB board 52 is supported by the central support strip 252 and the corner support block 251, and is secured by the barb at the front end of the third elastic locking foot 254. The PCB board 52 has a through hole for the positioning post 253 to pass through, ensuring the accuracy of the PCB board 52's installation position and allowing the socket circuit module 5 to be stably positioned in the high-voltage area 22.

[0054] There are two third elastic clips 254, located on the upper and lower sides of the mounting plate 21, respectively. When the isolation bracket 2 is installed into the mounting box 1, the outer walls of the two third elastic clips 254 abut against the inner wall of the mounting box 1, preventing outward elastic deformation that could cause the PCB board in the socket circuit module 5 to detach from the mounting plate 21.

[0055] The main board 91 in the control module 9 is installed on the back of the mounting plate 21, i.e., the rear weak point area 232. Relays, shunt resistors and other components are also connected to the main board 91.

[0056] The socket protection structure 32 includes a bottom cover 323, an elastic element 322, and a baffle 321.

[0057] The middle cover assembly 3 also includes a middle cover plate 33, which is installed on the opening of the mounting box 1 by a snap-fit ​​mechanism. The bottom cover 323 is installed on the back of the middle cover plate 33, forming a movable cavity between the bottom cover 323 and the middle cover plate 33. The baffle 321 is disposed in the movable cavity and can move up and down. The front side of the baffle 321 is inclined. The elastic element 322 is a spring, one end of which abuts against the baffle 321, and the other end abuts against the baffle wall 331 on the back of the middle cover plate 33, providing an elastic thrust to the baffle 321 to push the baffle 321 to block the inner insertion hole 31. When the plug is not inserted, the baffle 321 can block the inner insertion hole 31 to prevent foreign objects from contacting the contact copper piece 51. When the plug is inserted into the inner insertion hole 31, the plug presses against the inclined surface of the baffle 321, causing the baffle 321 to slide against the elastic force of the elastic element 322, and the plug can then pass through the inner insertion hole 31 and be inserted between the contact copper pieces 51.

[0058] This embodiment has three-pronged and two-pronged sockets. Therefore, two sets of baffles 321 and elastic members 322 are provided to block the two sets of sockets. At the same time, when the bottom cover 323 is installed on the middle cover plate 33, two movable cavities are formed for the installation of the two sets of baffles 321 and elastic members 322.

[0059] The bottom cover 323 has a limiting groove 3231 on its back surface, corresponding to the inner socket 31. The front end of the contact copper piece 51 in the socket circuit module 5 is located in the limiting groove 3231 and corresponds to the inner socket 31. When the plug is inserted, it passes through the outer socket 41 and the inner socket 31 in sequence and extends between the two contact copper pieces 51. The front ends of the two contact copper pieces are located in the limiting groove 3231, which can limit the contact copper pieces 51 and allow the plug to enter stably between the two contact copper pieces 51.

[0060] In practical use, no professional distribution box installation is required. Ordinary users can directly replace the 86-type wall socket, reducing the deployment time from 2 hours to 3 minutes.

[0061] It can be directly installed on an open wall, and the open wall structure improves heat dissipation efficiency by 200% and reduces the operating temperature by 15°C. At the same time, independent wall mounting frees up 35% of the space for the distribution box, solving the conflict of dense installation.

[0062] The built-in isolation bracket 2 uses a physical isolation mechanism to safely separate the high-voltage 220V power supply circuit from the low-voltage communication / control circuit;

[0063] The display screen 62 in the display module 6 can display various electrical parameters or other alarm parameters such as power, voltage, power, temperature, overvoltage, and undervoltage in real time on the socket, making it convenient for users to obtain the socket usage status. Secondly, the parameters of individual terminals can be reset on-site according to needs through the button 63.

[0064] The wireless communication module 7 can be connected to a smart home system to enable functions such as remote detection via app, power consumption analysis, and abnormal alarms.
