Description

Technical Field

[0001] This utility model relates to the field of electrical connection device technology, and in particular to a pressure-sensing smart socket. Background Technology

[0002] As an indispensable basic connection component in electrical systems, sockets are widely used in various environments such as homes, offices, and industrial settings. Their core function is to enable the transmission of electrical energy between the mains power and electrical equipment through contact between the internal spring contacts and the conductive terminals of the electrical plug. They typically include a housing, a socket in the housing, a conductive spring in the socket, and terminals for connecting to the mains power.

[0003] In existing sockets, the conductive contacts inside the sockets remain energized after being connected to mains power, meaning the socket is always in a power-ready state. While this design can meet the need for appliances to be plugged in and out at any time, it poses significant safety hazards. On the one hand, in scenarios such as homes with young children, children may insert their fingers or metal objects into the exposed sockets out of curiosity, which can easily lead to electric shock accidents and seriously threaten personal safety. On the other hand, the sockets lack a detection mechanism for the plug insertion status. When the plug is not fully inserted into the socket, the conductive contacts and the conductive terminals of the plug cannot form reliable contact, resulting in a "loose connection".

[0004] Loose connections can cause multiple hazards: First, a loose connection significantly increases contact resistance, generating a large amount of Joule heat when current flows through, causing a rapid increase in temperature in the socket area and on the plug's metal terminals. Prolonged high temperatures accelerate the aging and deformation of the socket contacts, and may even melt the insulating shell, shortening the socket's lifespan. Second, gaps caused by poor contact can easily lead to electric arcing. This arc can not only burn the contacts and plug terminals but also ignite dust, fabrics, and other flammable materials around the socket, causing a fire. Third, loose connections lead to unstable power supply circuits and frequent voltage fluctuations, affecting the normal operation of electrical equipment. This is especially true for precision electronic equipment (such as computers and appliance control boards), easily causing equipment crashes, data loss, or even damage to electronic components. Furthermore, the instantaneous high voltage generated by the arc can further increase the risk of electric shock, posing a secondary threat to user safety. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a pressure-sensing-based smart socket that can intelligently control power supply according to the actual insertion state of the plug, thereby improving the safety and reliability of the socket.

[0007] Furthermore, the mounting assembly includes a gantry frame, with both side plates of the gantry frame connected to the inner wall of the panel of the socket body. The pressure sensor is mounted on the inner wall of the middle plate of the gantry frame. A limiting groove is provided through the middle of each side plate. A guide shaft connected to the limiting groove and the panel of the socket body is fixedly installed in the limiting groove. Two control plates are provided inside the gantry frame. Each control plate has guide rings at both ends. The two guide rings of the control plate are slidably fitted with the guide shafts on both sides. An elastic component connects the two control plates. One control plate is in close contact with the sensing end of the pressure sensor, and the other control plate is in close contact with the actuating part of the triggering mechanism.

[0008] Furthermore, the triggering mechanism includes a rotating shaft and an actuating rod. The actuating part of the triggering mechanism is a cam coaxially mounted on the rotating shaft. The arc-shaped sidewall of the cam slides tightly against the corresponding control plate. A support plate is installed between the two side plates of the portal frame. A support hole is passed through the middle of the support plate. The rotating shaft slides through the support hole and extends to the outside of the portal frame. The rotating shaft is rotatably installed in the support hole and does not undergo axial displacement within the support hole. One end of the sidewall of the actuating rod is connected to the rotating shaft. A telescopic hole is provided through the part of the panel of the socket body close to the socket hole. An auxiliary hole adapted to the size and position of the telescopic hole is provided through the cover plate. A telescopic shaft is telescopically inserted into the telescopic hole.

The two trigger mechanisms are centrally symmetrical about the center line of the front and rear direction of the portal frame middle plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Safety protection is significantly improved: the socket contacts are energized only when the plug is fully inserted and the pressure sensor threshold is triggered. The contacts are not energized when the plug is not inserted, which prevents electric shock accidents caused by young children accidentally inserting foreign objects. It also eliminates safety hazards such as arc discharge and high temperature fire caused by loose connections.

[0015] To avoid the hazards of loose connections and protect equipment and sockets: Power is supplied only after the plug is fully inserted by pressure sensing, eliminating problems such as increased contact resistance and voltage fluctuations caused by loose connections, preventing socket springs from aging and deforming, and insulation shells from melting. At the same time, it prevents precision electronic equipment from crashing, losing data, or damaging components due to unstable power supply.

[0016] The structure is well-integrated and highly stable: the PCB board has strong and weak current related components installed on separate sides (microcontroller, driver module, AC-DC power module on one side, relay on the other side) to achieve strong and weak current isolation and reduce interference; the matching filter / anti-shake module and overcurrent protection module further improve signal transmission stability and circuit safety.

[0017] The mechanical structure is designed to be reliable and the reset is precise: the triggering mechanism works with the control board through the telescopic shaft, rotating shaft, cam and elastic component to ensure that the pressure signal is transmitted accurately when the plug is inserted or removed, without jamming or false triggering, and is compatible with the insertion action of different types of plugs.

[0018] Highly versatile and adaptable to various scenarios: It supports multiple socket types such as two-hole, three-hole, and two-hole + three-hole combinations. In the five-hole type, the dual trigger mechanism adopts central symmetry and can be adapted to two-hole and three-hole plugs respectively, meeting the power needs of different scenarios such as home and office.

[0043] As a preferred embodiment of the above embodiment, the socket 2 of the socket body 1 is configured as a two-hole, three-hole, or a combination of two-hole and three-hole sockets. In the type of two-hole and three-hole sockets, both the two-hole sockets and the three-hole sockets are adapted to a trigger mechanism. The two trigger mechanisms are centrally symmetrical about the centerline of the front and rear directions of the middle plate of the portal frame 12. In this embodiment, Different types of sockets 2 and symmetrical triggering mechanisms: Two-hole, three-hole, and five-hole combination designs are available to accommodate different electrical plugs; in the five-hole type, the dual triggering mechanism is symmetrical about the center line of the middle plate of the gantry frame 12, and can respond to the insertion action of two-hole and three-hole plugs respectively, ensuring that when a plug is inserted into any socket 2 and the threshold is reached, the corresponding control logic can be triggered, thus improving the product's versatility.

[0044] The working principle of this utility model is as follows: This invention achieves intelligent power supply control through a closed-loop process of "mechanical triggering - signal processing - electrical control - reset": Power supply preparation: The mains power is connected to the socket body 1 through the terminal 4. The AC-DC power module 10 converts the 220V AC power into low voltage power to power the microcontroller 7, pressure sensor 11, and drive module 9. All components share a common ground to form a stable working circuit.

[0045] Insertion trigger: When the electrical plug is inserted into the socket 2, it squeezes the telescopic shaft 19 near the socket 2. The telescopic shaft 19 retracts inward along the telescopic hole, pushing the action rod 16 to rotate around the rotating shaft 15. The rotating shaft 15 drives the cam 17 to rotate synchronously. The arc surface of the cam 17 squeezes the control plate. The control plate slides along the guide shaft 13 and compresses the elastic component, finally applying a squeezing force to the pressure sensor 11.

[0046] Signal processing and control: When the plug is fully inserted and the squeezing force reaches the preset threshold, the pressure sensor 11 converts the mechanical pressure into an electrical signal. After the signal filtering / anti-shake module 21 filters out interference, the signal is transmitted to the microcontroller 7. The microcontroller 7 determines that the signal meets the standard and outputs a control command to the drive module 9. The drive module 9 amplifies the signal and drives the coil of the relay 8 to be energized. The contacts of the relay 8 are energized, and the mains power is transmitted to the spring 3 through the current protection module 20 and the contacts of the relay 8, and the socket starts to supply power.

[0047] Unplugging and Resetting: After the plug is unplugged, the elastic component releases its elastic force, pushing the control board back to its original position. Cam 17, rotating shaft 15, and actuating rod 16 reset synchronously, and telescopic shaft 19 extends along the telescopic hole to its initial position. Pressure sensor 11 disengages from the pressure and stops outputting electrical signals. After receiving the reset signal, microcontroller 7 controls drive module 9 to stop outputting, relay 8 coil is de-energized, contacts open, and spring 3 is de-energized to prevent no-load energization.

[0048] Safety protection: The overcurrent protection module 20 monitors the live wire current in real time and automatically cuts off the circuit when overloaded; the strong and weak current separation layout, common ground design and filter anti-jitter module ensure stable circuit operation without interference or false triggering, comprehensively improving the safety and reliability of use.

[0049] The microcontroller 7, relay 8, drive module 9, AC-DC power module 10, pressure sensor 11, signal filtering / anti-shake module 21, and overcurrent protection module 20 used in this utility model are all mature commercial electronic components / modular products that can be directly purchased on the market. There is no need for independent research and development or structural improvement. The functions of this solution can be realized simply through standardized circuit connection and logic programming.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
