[0001] This utility model relates to the technical field of sockets, specifically a socket with a detection structure. Background Technology

[0002] A socket is a receptacle with one or more electrical connections that can be inserted, facilitating connection to other circuits. The connection and disconnection of this section of the circuit are achieved through the connection and disconnection of the wiring and copper components.

[0003] A socket disclosed in Chinese Patent Publication No. CN206379539U has the following technical features: it includes an upper cover plate and a lower cover plate that interlock with each other, and a protective door located in the space between the upper cover plate and the lower cover plate after they interlock. The upper cover plate has a first socket for inserting a double-prong plug and a second socket for inserting a three-prong plug. The lower cover plate has a first conductive piece corresponding to the first socket and a second conductive piece corresponding to the second socket. The protective door includes a first protective member that covers the first socket when the double-prong plug is not inserted, and a second protective member that covers the second socket when the three-prong plug is not inserted. A spring is provided between the first protective member and the second protective member. When the double-prong plug is inserted, the first protective member moves toward the second protective member and compresses the spring to expose the first socket. When the three-prong plug is inserted, the second protective member moves toward the first protective member and compresses the spring to expose the second socket.

[0004] In the above solution, protection is achieved by inserting the plug into the socket and squeezing and moving the first protective element, the second protective element, and the spring. However, this solution has the following drawback: the socket does not have a detection function, so it cannot know whether the plug is fully inserted or accidentally pulled out, which poses a potential danger. Utility Model Content

[0005] The purpose of this invention is to provide a socket with a detection structure to solve the problem that the socket lacks a detection function, thus making it impossible to know whether the plug is fully inserted or accidentally pulled out, which poses a potential danger.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a socket with a detection structure, including an upper shell, which is bolted to the top surface of a bottom shell. Two insulating seats are provided on the upper shell. A PCB board is fixed to the top surface of the upper shell. Both insulating seats are fixed to the PCB board. A top cover is fixed to the top surface of each of the two insulating seats. Two Hall effect sensors are provided on the PCB board. A mounting base is fixed inside each of the two insulating seats. A first stop is movably disposed within the mounting base. A first inclined groove is formed on the top surface of the first stop. A second stop is movably disposed within the mounting base. A second inclined groove is formed on the top surface of the second stop. An L-shaped frame is fixed to the bottom surface of both the first and second stops. A first magnet is fixed inside the L-shaped frame of the first stop, and a second magnet is fixed inside the L-shaped frame of the second stop. A spring is fixed between the front side of the first stop and the interior of the second stop.

[0007] Preferably, the inner bottom surface of the upper shell is provided with a mounting hole, the PCB board is provided with an LED light, the top of the LED light passes through the mounting hole, the positive terminal of the LED light is connected to the positive terminal of the Hall sensor, and the negative terminal of the LED light is connected to the negative terminal of the Hall sensor through a resistor.

[0008] Preferably, the front side of the first stop and the interior of the second stop are both fixed with limiting shafts, and the spring is wrapped around the two limiting shafts.

[0009] Preferably, two positioning plates are fixed on the top surface of the PCB board, and two positioning holes are opened on the inner bottom surface of the upper shell, with the two positioning holes respectively positioning the two positioning plates.

[0010] Preferably, a horn is fixed inside the upper shell, and a sound outlet is provided on the front side of the upper shell.

[0011] Preferably, a silicone pad is fixed to the top surface of both of the top covers, and each of the two silicone pads has a slot that matches a plurality of insertion holes.

[0012] Compared with existing technologies, a socket with a detection structure that adopts the above technical solution has the following advantages: I. During use, through the coordinated action of the upper shell, bottom shell, insulating base, PCB board, top cover, Hall sensor, mounting base, first stop, first inclined slot, second stop, second inclined slot, L-shaped bracket, first magnet, second magnet and spring, it can detect the insertion of two-prong plugs and three-prong plugs into the socket. It can monitor the usage status of the socket in real time. When the socket has potential dangers such as abnormal insertion or removal or overload, it can detect them in time and take corresponding measures, effectively improving electrical safety and avoiding electrical faults and safety accidents caused by improper insertion or removal of plugs, providing users with a safer and more reliable power environment; Second, during use, as the first or second magnet gradually moves away from the Hall sensor, the electrical signal in the circuit containing the LED light weakens, and the LED light gradually turns off, clearly reflecting the state of the plug being unplugged, providing users with intuitive visual feedback. The limiting shaft restricts the movement trajectory of the spring, preventing it from shifting or twisting during compression and extension, ensuring smooth and stable movement of the first and second stops, and improving the stability and reliability of the entire detection structure. Thirdly, during use, the positioning plate accurately inserts into the positioning hole to assist in positioning the upper shell, ensuring it is in the correct installation position and improving installation convenience and accuracy. The sound outlet allows sound to propagate clearly, ensuring users can hear the prompts promptly. The silicone pad utilizes its elasticity and sealing properties to quickly block moisture, preventing it from entering the socket's internal holes and electrical components.

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-4As shown, a socket with a detection structure includes an upper shell 1, which is bolted to the top surface of a bottom shell 2. Two insulating seats 3 are provided on the upper shell 1. A PCB board 4 is fixed to the top surface of the upper shell 1. Both insulating seats 3 are fixed to the PCB board 4. A top cover 5 is fixed to the top surface of each of the two insulating seats 3. Two Hall effect sensors 6 are provided on the PCB board 4. A mounting base 7 is fixed inside each of the two insulating seats 3. A first stop 8 is movably disposed within the mounting base 7. A first inclined groove 9 is formed on the top surface of the first stop 8. A second stop 10 is movably disposed within the mounting base 7. A second inclined groove 11 is formed on the top surface of the second stop 10. L-shaped brackets 12 are fixed to the bottom surfaces of both the first stop 8 and the second stop 10. A first magnet 13 is fixed inside the L-shaped bracket 12 of the first stop 8, and a second magnet 14 is fixed inside the L-shaped bracket 12 of the second stop 10. A spring 15 is fixed between the front side of the first stop 8 and the interior of the second stop 10.

[0020] During use, when the user inserts the two-prong plug into the insulating base 3 sequentially from the upper shell 1 and the upper cover 5, the pins of the two-prong plug are inserted into the two first inclined slots 9 on the first stop 8. As the two-prong plug continues to be pressed down, its pins exert a squeezing effect on the first inclined slots 9. This squeezing force pushes the first stop 8 and the L-shaped bracket 12 and the first magnet 13 fixed on it to move forward. During this process, the spring 15 is gradually compressed. As the first stop 8 moves, the first magnet 13 gradually approaches the Hall sensor 6. When the two-prong plug is fully inserted into the socket, the first magnet 13 is exactly above the Hall sensor 6. At this time, the Hall sensor 6 detects the change in magnetic field and is triggered, indicating that a plug has been inserted into the socket. Conversely, when the two-prong plug is pulled out, the compressed spring 15 generates an elastic restoring force, pushing the first stop 8 and the L-shaped bracket 12 and the first magnet 13 to the rear to reset, so that the first magnet 13 is away from the Hall sensor 6. The Hall sensor 6 is not triggered, indicating that no plug has been inserted into the socket.

[0021] When the user inserts the three-prong plug into the insulating base 3 sequentially from the upper shell 1 and the upper cover 5, the pins of the three-prong plug are inserted into the two second inclined slots 11 on the second stop 10. As the three-prong plug continues to be pressed down, its pins squeeze the second inclined slots 11, pushing the second stop 10 and its L-shaped bracket 12 and second magnet 14 to move backward. The spring 15 is also gradually compressed, and the second magnet 14 gradually approaches the Hall sensor 6. When the three-prong plug is fully inserted, the second magnet 14 is located directly above the Hall sensor 6, and the Hall sensor 6 is triggered, indicating that a plug has been detected in the socket. When the three-prong plug is pulled out, the spring 15 pushes the second stop 10 and its L-shaped bracket 12 and second magnet 14 to move forward and reset, and the second magnet 14 moves away from the Hall sensor 6. The Hall sensor 6 is not triggered, indicating that no plug has been detected in the socket.

[0022] Through the coordinated action of the upper shell 1, bottom shell 2, insulating base 3, PCB board 4, top cover 5, Hall sensor 6, mounting base 7, first stop 8, first inclined groove 9, second stop 10, second inclined groove 11, L-shaped bracket 12, first magnet 13, second magnet 14, and spring 15, the system can detect the insertion of two-prong and three-prong plugs into the socket. It can monitor the socket's usage status in real time. When the socket experiences potential dangers such as abnormal insertion / removal or overload, it can promptly detect and take corresponding measures, effectively improving electrical safety and avoiding electrical faults and safety accidents caused by improper insertion or removal of plugs, thus providing users with a safer and more reliable electrical environment.

[0023] like Figures 1-3 As shown, the inner bottom surface of the upper shell 1 has a mounting hole 16, and the PCB board 4 has an LED light 17. The top of the LED light 17 passes through the mounting hole 16. The positive terminal of the LED light 17 is connected to the positive terminal of the Hall sensor 6, and the negative terminal of the LED light 17 is connected to the negative terminal of the Hall sensor 6 through a resistor.

[0024] During use, when the first magnet 13 or the second magnet 14 approaches the Hall sensor 6, the change in the electrical signal of the Hall sensor 6 causes the connected LED light 17 circuit to conduct, and the LED light 17 gradually lights up. Its brightness gradually increases as the distance between the magnet and the Hall sensor 6 decreases, intuitively showing the degree of plug insertion. When the first magnet 13 or the second magnet 14 gradually moves away from the Hall sensor 6, the electrical signal of the circuit containing the LED light 17 weakens, and the LED light 17 gradually turns off, clearly reflecting the state of plug removal and providing users with intuitive visual feedback.

[0025] like Figures 1-4 As shown, the front side of the first stop 8 and the interior of the second stop 10 are both fixed with limit shafts 18. Springs 15 are wrapped around the two limit shafts 18. The top surface of the PCB board 4 is fixed with two positioning plates 19. The bottom surface of the upper shell 1 has two positioning holes 20, which respectively position the two positioning plates 19.

[0026] During use, when the first stop 8 or the second stop 10 moves during plug insertion or removal, the limiting shaft 18 restricts the movement trajectory of the spring 15, preventing the spring 15 from shifting or twisting during compression and extension. This ensures smooth and stable movement of the first stop 8 and the second stop 10, improving the stability and reliability of the entire detection structure. When the operator installs the upper shell 1 onto the bottom shell 2, the positioning plate 19 accurately inserts into the positioning hole 20 to assist in positioning the upper shell 1, ensuring it is in the correct installation position and improving the convenience and accuracy of installation.

[0027] like Figures 1-3As shown, a speaker 21 is fixed inside the upper shell 1, and a sound outlet 22 is opened on the front side of the upper shell 1. A silicone pad 23 is fixed on the top surface of both upper covers 5, and a slot matching several insertion holes is opened on both silicone pads 23.

[0028] During use, the speaker 21 can emit an audible alert when the plug is inserted or removed, or when a malfunction occurs, further enhancing the warning effect. This is especially suitable for scenarios where users cannot visually monitor the socket status in a timely manner. The sound outlet 22 ensures that the sound is clearly transmitted, guaranteeing that users can hear the alert promptly. The silicone pad 23 is made of highly elastic and aging-resistant silicone material, fitting tightly around the socket holes. The slits on the silicone pad 23 that match several socket holes facilitate plug insertion. When water droplets or liquids splash onto the socket surface, the silicone pad 23 utilizes its elasticity and sealing properties to quickly block the moisture, preventing it from entering the socket holes and electrical components inside the socket.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
