[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] This embodiment relates to a socket, see reference Figure 1 , Figure 2 as well as Figure 3 The device includes a housing, including an upper cover 10 and a lower cover 11. The top of the upper cover 10 is provided with at least one socket 101, and the bottom of the lower cover 11 is provided with a mounting groove 111. The device also includes a control circuit board 12, on which a relay is provided. The control circuit board 12 is detachably installed in the mounting groove 111. The relay is electrically connected to the live wire circuit of the socket 101 and is used to control the on / off state of the live wire circuit.

[0022] The aforementioned socket 101 can be a socket 101 with a live wire and a neutral wire, or it can be a socket 101 with a live wire, a neutral wire, and a ground wire. The aforementioned control circuit board 12 can adopt the following... Figure 3 The blank board shown integrates a variety of electronic components, including but not limited to a three-axis accelerometer, a three-axis gyroscope, button A, button B, I²C interface, Type-C interface, I / O interface, microSD card interface, USB-A interface, buzzer, indicator light, Wi-Fi / Bluetooth antenna, microphone, light sensor, Home button, touch screen, and gold finger interface, etc.

[0023] It should be noted that, in addition to using a blank board, other control circuit boards 12 with the same or similar functions can be selected according to actual needs, and the types and layout of components on the control circuit board 12 can be adjusted according to product functional requirements, and are not limited to the specific forms mentioned above.

[0024] The control circuit board 12 is fixed in the mounting groove 111, and the relay on its surface is electrically connected to the live wire circuit of the socket 101 to control the circuit on and off.

[0025] The mounting groove 111 refers to the receiving structure formed by the inward recess at the bottom of the lower cover 11. It can be integrally formed using injection molding, with the recess depth slightly greater than the thickness of the circuit board. This structure restricts the lateral movement of the circuit board through the side walls, while the bottom plane provides support.

[0026] The detachable installation refers to the formation of a non-movable connection between the circuit board and the mounting slot 111, which can be achieved through detachable snap-fit ​​or screw fastening. This measure ensures that the circuit board remains stable under vibration or external force, and allows for disassembly when necessary.

[0027] The live wire circuit connection refers to the conductive path formed between the relay contacts and the conductive component of socket 101, which can be achieved by soldering copper wires or crimping flexible contact pieces. This connection method ensures the reliability of current transmission.

[0028] Specifically, the recessed structure of the mounting groove 111 is precisely sized during the injection molding stage, and the circuit board is simply inserted into the groove for positioning during assembly. The sidewall of the groove and the edge of the circuit board form a clearance fit to prevent horizontal displacement. The relay contacts are connected to the live wire terminal of the socket 101 via wires. Once the circuit board is fixed, the contact position maintains a constant distance from the terminal of the socket 101 to avoid poor contact.

[0029] Preferably, refer to Figure 1 It also includes a mounting plate 13, which is located between the upper cover 10 and the lower cover 11. A mounting bracket 14 is fixed on the mounting plate 13, and the mounting bracket 14 is used to fix the insertion hole 101.

[0030] The mounting plate 13 refers to a plate-like structure located inside the outer casing that provides support and positioning. It can be made of injection-molded flame-retardant insulating material, and its edges can be fitted with snaps or screw holes for secure connection to the top cover 10. The mounting bracket 14 is a structural component fixed to the mounting plate 13 to support the socket 101. It can be a combination of a metal contact piece and a plastic support, with the contact piece providing conductive connection and the support providing mechanical restraint. The socket 101 is a conductive interface for inserting an external plug, which can be formed by injection molding a metal conductor, and its position is constrained by the mounting bracket 14.

[0031] Specifically, the mounting plate 13 is sandwiched between the upper cover 10 and the lower cover 11, forming an intermediate support layer. The mounting bracket 14 is fixed to the surface of the mounting plate 13 by injection molding or screws, and the socket 101 is embedded in the mounting bracket 14 and electrically connected to the control circuit board 12 through a metal contact. During assembly, the mounting plate 13, as an independent component, can be pre-positioned as the mounting bracket 14, and then fixed to the upper cover 10 by clips or screws, thereby achieving precise positioning of the socket 101.

[0032] Preferably, the mounting bracket 14 includes a metal contact assembly and a safety door assembly, the safety door assembly including a relatively sliding baffle and a return spring cooperating with the baffle.

[0033] Among them, the metal contact assembly refers to the metal structure used to carry the plug electrodes and establish a conductive connection. Specifically, it can be made of copper alloy stamping parts, and its surface can be plated with nickel or silver to enhance conductivity.

[0034] The safety door assembly refers to the mechanical protective structure installed at the entrance of the socket 101. Specifically, it can be implemented by combining injection-molded slide rails and metal baffles to prevent foreign objects from being inserted.

[0035] Among them, the baffle refers to a metal sheet that can slide along the axial direction of the insertion hole 101. Specifically, it can be formed by stamping a stainless steel sheet with a thickness of 0.5-1.2 mm, and its edge is provided with guide protrusions to cooperate with the slide rail.

[0036] Among them, the reset spring refers to a helical compression spring that provides elastic restoring force. Specifically, it can be made of spring steel wire with a wire diameter of 0.3-0.6 mm and installed between the baffle and the mounting plate 13.

[0037] Specifically, when the plug is inserted into the socket 101, the plug electrodes push the baffle to slide along the slide rail. At this time, the return spring is compressed, and the metal contact assembly forms a stable contact with the plug electrodes. When the plug is pulled out, the return spring pushes the baffle back to its initial position, completely sealing the entrance of the socket 101. The metal contact assembly is fixed to the mounting bracket 14 by riveting or welding, and the sliding stroke of the baffle can be limited by the length of the slide rail.

[0038] Preferably, the mounting plate 13 is fixedly connected to the upper cover 10 by a snap fastener or screw.

[0039] Among them, the snap-fit ​​refers to a connection structure with elastic deformation capability, which can be implemented by injection molding an integrated protrusion and groove structure, and achieves quick positioning and fixation of the mounting plate 13 and the top cover 10 through the snap-fit ​​action. The screw refers to a threaded fastener, which can be implemented by a structure of metal or plastic self-tapping screws and pre-embedded nuts, and forms a rigid connection by rotation and tightening.

[0040] Specifically, during assembly, when a snap-fit ​​connection is used, the edge of the mounting plate 13 can be provided with multiple elastic claws, and the upper cover 10 has corresponding slots. Vertical pressing causes the claws to engage with the slots for fixation. When a screw connection is used, the mounting plate 13 can be provided with a boss with a through hole, and the upper cover 10 has corresponding threaded posts. Screws pass through the through holes and are screwed into the threaded posts to form a lock. Both connection methods ensure a stable connection between the mounting plate 13 and the upper cover 10, preventing displacement of the mounting plate 13 during insertion and removal.

[0041] Preferably, refer to Figure 1 It also includes a hollow support ring 15 located between the mounting plate 13 and the lower cover 11, the hollow support ring 15 being used to form a through cavity between the mounting plate 13 and the lower cover 11.

[0042] Among them, the hollow support ring 15 refers to a support component with an annular cavity structure, which can be made of injection-molded flame-retardant insulating material. Its outer diameter can form an interference fit with the inner diameter of the mounting groove 111 of the lower cover 11, and provide uniform support force to the mounting plate 13 through the annular support surface.

[0043] The through cavity refers to a continuous channel space enclosed by the hollow support ring 15. Specifically, it can be formed by setting an annular sidewall and matching the upper and lower end faces. The cross-sectional shape of the cavity can be circular, rectangular or other regular geometric shapes, used to accommodate fasteners and electrical wiring.

[0044] Specifically, during assembly, the hollow support ring 15 is press-fitted between the mounting plate 13 and the lower cover 11, with its annular sidewall in close contact with the inner wall of the mounting groove 111 of the lower cover 11. When the fastener passes through the first through hole at the bottom of the mounting plate 13, it can extend downward along the annular cavity of the hollow support ring 15, eventually forming a threaded connection with the second through hole of the lower cover 11. This structure creates a stable three-point support system between the mounting plate 13 and the lower cover 11, while the through cavity provides a guide channel for fastener installation.

[0045] Preferably, the bottom of the mounting plate 13 is provided with a first through hole, and the lower cover 11 is provided with a second through hole at the position corresponding to the first through hole. The fastener passes through the first through hole, the cavity of the hollow support ring 15 in sequence and cooperates with the second through hole to fix the mounting plate 13 and the lower cover 11.

[0046] The first through hole refers to a through-hole formed at the bottom of the mounting plate 13, which can be circular or square, used to guide the fastener through the mounting plate 13. The second through hole refers to a hole on the surface of the lower cover 11 corresponding to the position of the first through hole, which can be threaded or smooth, used to form a fixed fit with the end of the fastener. The internal cavity of the hollow support ring 15 provides a passage for the fastener. The fastener refers to the mechanical fixing element used to connect the mounting plate 13 and the lower cover 11, which can be a combination of bolts and nuts or self-tapping screws, achieving structural locking by applying axial pressure.

[0047] Specifically, during assembly, the mounting plate 13 is aligned with the second through hole of the lower cover 11 through the first through hole, and the cavity of the hollow support ring 15 serves as the passageway for the fasteners. After the fasteners pass through the first through hole and the cavity of the hollow support ring 15 in sequence, their ends engage with the second through hole via a threaded or interference fit, creating a rigid connection between the mounting plate 13 and the lower cover 11. This structure avoids gaps that may occur with traditional adhesive or snap-fit ​​connections, and the limiting effect of the hollow support ring 15 prevents the fasteners from becoming misaligned during installation.

[0048] Preferably, the outer shell, mounting plate 13, and hollow support ring 15 are all made of flame-retardant insulating material.

[0049] Among them, flame-retardant insulating material refers to non-conductive material that has the ability to inhibit the spread of combustion in high-temperature or open-flame environments. Specifically, it can be achieved using V-0 grade flame-retardant polycarbonate material, which has self-extinguishing properties and a volume resistivity higher than 10^14 Ω·cm in combustion tests. The outer shell, mounting plate 13, and hollow support ring 15 serve as the main support structures for the live components inside the socket. The flame-retardant insulating material can prevent the spread of combustion caused by internal circuit short circuits, while also preventing current from being conducted to the outside through the structural components.

[0050] Specifically, the outer casing, as the main structure enclosing the control circuit board 12 and mounting bracket 14, is made of flame-retardant insulating material to block the risk of combustion caused by abnormal heating of the internal circuit. The mounting plate 13, as the intermediate layer supporting the mounting bracket 14, has flame-retardant properties to prevent electrical sparks from poor contact of the socket 101 from igniting surrounding components. The hollow support ring 15, as a barrier structure through the cavity, is made of flame-retardant insulating material to prevent fasteners from contacting live parts and creating a leakage path. During assembly, the outer casing, mounting plate 13, and hollow support ring 15, made of flame-retardant insulating material, are integrated through injection molding to ensure that each component maintains shape stability under high-temperature conditions.

[0051] Preferably, refer to Figure 2 The bottom of the lower cover 11 has multiple ventilation holes 112.

[0052] The bottom of the lower cover 11 refers to the outer surface area of ​​the lower half of the socket shell. Specifically, it can be achieved by using injection molding to form a structure with holes, for example, by evenly distributing holes at the bottom through mold design.

[0053] Among them, the multiple ventilation holes 112 refer to the holes that penetrate the inner and outer surfaces of the bottom of the lower cover 11. Specifically, they can be composed of a central circular hole and four elliptical holes evenly distributed along the circumference, or they can be realized by using circular, square or other regular shaped hole structures, such as circular holes with a diameter of 1-3 mm or square holes with a side length of 2-4 mm, and the hole spacing can be 5-10 mm.

[0054] Specifically, the bottom of the lower cover 11 forms an airflow channel through multiple ventilation holes 112. When the control circuit board 12 operates within the mounting slot 111, the heat generated by electronic components such as relays is exhausted through the ventilation holes 112 via air convection. For example, in a high-temperature environment, cool external air enters the housing through the bottom ventilation holes 112, forming a circulation with the hot air around the circuit board, thereby reducing the internal temperature. Furthermore, the distribution density and size of the ventilation holes 112 can be adjusted according to heat dissipation requirements; for example, a higher density of ventilation holes 112 can be provided in the area corresponding to the relays to enhance local heat dissipation.

[0055] Preferably, refer to Figure 1 The top of the cover 10 is also provided with a multi-function interface area, which includes at least one USB interface 102 and a control button 103 arranged adjacent to it.

[0056] Among them, USB interface 102 refers to a power transfer interface that conforms to the Universal Serial Bus standard. Specifically, it can be implemented using a Type-A or Type-C interface to provide DC power to external electronic devices.

[0057] Among them, the control button 103 refers to a physical or touch-operated component used to trigger circuit control signals. Specifically, it can be implemented using a mechanical micro switch or a capacitive touch sensor, and is used to manually switch the working mode or on / off state of the socket.

[0058] Specifically, a multi-functional interface area is located on the top of the cover 10, separated from the jack 101 area. This area integrates a USB interface 102 and a control button 103 through injection molding or embedded assembly. The power input terminal of the USB interface 102 is electrically connected to the DC-DC conversion module of the control circuit board 12, and the signal output terminal of the control button 103 is electrically connected to the logic processing unit of the control circuit board 12. When the user inserts a USB cable, the control circuit board 12 converts AC power to an appropriate voltage through the DC-DC conversion module to charge the electronic device; when the user presses the control button 103, the logic processing unit switches the relay on / off state or adjusts the output power of the USB interface 102 according to preset instructions.

[0059] In some specific embodiments, there may be two USB ports 102, symmetrically distributed on both sides of the control button 103; LED indicator lights may be provided on the surface of the control button 103, for example, by aligning and installing them with LED beads on the circuit board through a light-transmitting material, to display the current working status of the socket.

[0060] Preferably, the control circuit board 12 includes a circuit unit for acquiring the hardware addresses of each connected device in the target wireless network; a circuit unit for performing matching processing based on the preset target hardware address and the hardware addresses of each connected device to obtain a matching result; and a circuit unit for controlling the socket to enter the corresponding working state based on the matching result.

[0061] Among them, the hardware address refers to the unique identifier of a device in the network, which can be implemented using the MAC address, and is used to identify whether a specific device is connected to the target wireless network.

[0062] The matching process refers to comparing the preset target hardware address with the address of the connected device. Specifically, it can be implemented using the address comparison algorithm built into the microcontroller, which completes the address matching through bit-by-bit verification or hash operation.

[0063] The working state includes a powered-on state or a powered-off state, which can be achieved by controlling the on / off state of the live wire circuit through a relay drive circuit. When the matching is successful, the relay is triggered to close; otherwise, it is opened.

[0064] Specifically, when the socket connects to the wireless network, the first circuit unit in the control circuit board 12 continuously scans the hardware addresses of connected devices within the network and transmits the address information to the second circuit unit. The second circuit unit matches the preset target hardware address with the scan results. If a match is found, a successful match signal is generated; otherwise, a failed match signal is generated. The third circuit unit drives a relay to operate based on the matching signal. For example, when a target device is detected connecting to the network, the live wire circuit is automatically turned on; otherwise, the power is cut off. This achieves intelligent on / off control based on the device's connection status, avoiding human error.

[0065] Understandably, in a home setting, when a user's device is detected to have disconnected from the wireless network, it can be determined that the user has left the area where the outlet is located, and power-off control can be automatically executed. This prevents high-power appliances such as electric blankets and electric kettles, or chargers with overheating potential, from running for extended periods, which could lead to overheating or even fire risks. Conversely, when a user's device is detected to have successfully connected to the wireless network and its hardware address matches the preset target hardware address, power to the outlet can be automatically restored, ensuring the user's convenience and safety when using electricity.

[0066] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
