Description

Technical Field

[0001] This invention relates to the field of plug technology, and more specifically, to a thin plug with a foolproof structure. Background Technology

[0002] Slim plugs with foolproof designs are becoming increasingly important in modern electronic devices, especially given the demands for miniaturization and high performance. The foolproof design ensures correct insertion and removal, preventing equipment damage or electrical malfunctions caused by incorrect operation. These plugs are widely used in consumer electronics, automotive, medical, and industrial fields, providing assurance for stable equipment operation and user safety. With continuous technological advancements, future foolproof plugs will play an even greater role in improving device performance and user experience.

[0003] A search revealed a thin plug proposed in Chinese Patent (Announcement No.: CN218919363U), which includes a base, wires, a live wire assembly and a neutral wire assembly fixed to the base. The live wire assembly and the neutral wire assembly are spaced apart. The live wire assembly includes a live wire pin and a first twisted socket. The neutral wire assembly includes a neutral wire pin and a second twisted socket. One end of each of the live wire pins and the neutral wire pins is fixed to the base and extends from the surface of the base. One end of the first twisted socket surrounds the live wire pin and is fixedly connected to it. The other end extends outward from the side of the base and is electrically connected to the wires. The top of the first twisted socket is not higher than the top of the live wire pin. One end of the second twisted socket surrounds the neutral wire pin and is fixedly connected to it. The other end extends outward from the side of the base and is electrically connected to the wires. The top of the second twisted socket is not higher than the top of the neutral wire pin.

[0004] While the aforementioned patents can achieve the function of preventing mistakes, they still have the following shortcomings in use: When connecting a plug to a socket, it is not always possible to clearly determine the direction of the plug. Sometimes it is necessary to move it left or right to align the prongs and sockets. If the plug design is not clear, users may encounter situations where they need to move the plug left or right to insert it correctly. This not only reduces the efficiency of plugging and unplugging, but also easily leads to poor contact and affects the stability of the electrical connection.

[0005] Therefore, we have made improvements by proposing a thin plug with a foolproof structure to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a thin plug with a foolproof structure to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A thin plug with a foolproof design, including a socket, and further comprising: Two first limiting blocks are symmetrically and fixedly connected to both sides of the inner wall of the socket; The adapter pin is rotatably connected to the inside of the socket.

[0008] As a preferred technical solution of this application, the limiting component includes first sliding grooves respectively opened on both sides of the bottom wall of the socket and on both sides of the bottom wall of the adapter post. A first spring is fixedly connected to the inner wall of the first sliding groove on the side away from each other. A second limiting block is fixedly connected to the inner side of the first sliding groove on the opposite side of the first spring. A first limiting rod is fixedly connected to the side wall of the second limiting block on the side away from each other.

[0009] As a preferred technical solution of this application, the sealing assembly includes a connecting frame symmetrically rotatably connected to the outer walls on both sides of the rotating shaft. A sealing plate is fixedly connected to the outer wall of the connecting frame on the side away from the fixed plate. A second sliding groove is opened on the top wall of one side of the sealing plate, and a rack is fixedly connected to the side wall of one side of the second sliding groove.

[0010] As a preferred technical solution of this application, the angle limiting component includes a fixed sleeve fixedly connected to the outer wall of the connecting frame on the side away from each other, a stress spring rotatably connected to the outer walls of both ends of the rotating shaft, and a stress rod fixedly connected to the outer wall of the fixed plate on the side facing each other. One end of the stress spring is fixedly connected to the end of the fixed sleeve, and the other end of the stress spring is fixedly connected to the end of the stress rod.

[0011] As a preferred technical solution of this application, the connecting component includes a second connecting line symmetrically and fixedly connected to both sides of the bottom of the adapter post, a connecting post slidably connected to the inner side of the second connecting line, a graphite brush fixedly connected to the bottom wall of the connecting post, a second spring fixedly connected to the top wall of the graphite brush, the top end of the second spring fixedly connected to the inner wall of the second connecting line, and the top end of the second connecting line fixedly connected to the inner wall of the slot.

[0012] As a preferred technical solution of this application, the magnetic suction assembly includes a second magnet rotatably connected to the inner side of the second limiting groove, a support shaft fixedly connected to the inner side of the second magnet, and a gear fixedly connected to the end of the support shaft away from the second magnet, the gear meshing with a rack.

[0013] As a preferred technical solution of this application, the power connection assembly includes a third sliding groove formed inside the fixed cylinder, two sliding rods are fixedly connected to the two sides inside the third sliding groove, a third magnet is slidably connected to the outer side of the middle section of the sliding rod, and a sliding copper frame is fixedly connected to the top wall of the third magnet, and the sliding copper frame is slidably connected to the sliding rod.

[0014] As a preferred technical solution of this application, the wire end fixing assembly includes a fixing copper column fixedly connected to the top wall of the fixing cylinder, and a fixing bolt is threadedly connected to the inner side of the top of the fixing copper column.

[0015] As a preferred technical solution of this application, the sealing shell is composed of two side walls, and one side wall is connected to the partition plate by screws.

[0016] As a preferred technical solution of this application, when the second connecting line is not electrically connected to the first connecting line, the first limiting rod at the bottom is inserted into the inner side of the bottom of the first slot to limit the angle of the adapter post and the socket.

[0017] In the scheme of this application: 1. The sealing plate in the sealing assembly guides the pins, while the slot limits the bottom of the sealing shell, ensuring insertion only when the angle between the sealing shell and the slot is correct. Multiple signal arrows work together to help users quickly align the pins with the first slot, greatly simplifying the insertion and removal process. This design improves the accuracy of insertion and removal, reduces the risk of poor contact, and ensures a stable and reliable electrical connection. The signal arrows also provide clear insertion guidance, preventing mis-insertion and improving ease of use. Furthermore, the sealing assembly effectively prevents dust and moisture from entering, improving protection and extending service life. 2. By using the pins to support the sealing plates on both sides during insertion, the sealing plates are made to fit tightly against the sides of the pins. The racks on both sides of the sealing plates drive the second magnet to rotate, thereby adjusting the positive and negative poles of the second magnet. The top of the second magnet is adjusted to be the same as the bottom of the third magnet, which is the same as the anode or cathode. The third magnet then pushes the sliding copper frame upward, connecting the first and second copper plates to achieve the effect of power supply. This ensures the accuracy and stability of the electrical connection and reduces the risk of poor contact. 3. By pressing down the first limiting rod at the bottom of the adapter post during the insertion of the plug into the first slot, and simultaneously pressing down the first limiting rod on the inside of the socket through the first limiting rod on the inside of the adapter post, the first limiting rod on the inside of the socket is pushed out of the first slot, thereby removing the restriction on the socket and the adapter post, allowing the adapter post to rotate inside the socket, thereby connecting the second spring at the bottom of the second connecting wire with the first connecting wire, realizing power supply, thus increasing the safety during the insertion process, avoiding accidental contact of fingers with the plug pins and preventing electric shock, and greatly increasing the safety of use; 4. Through the above design, the solution is designed to be unique, preventing other plugs from being inserted and rendering them unusable even if forcibly inserted. This avoids electrical short circuits and overloads caused by unsuitable plugs or poor contact, improving the safety of the equipment and users. It also ensures that the plug and socket pairing is specifically designed for a particular type of equipment or electrical system, preventing incompatible plugs from being connected to other devices. This simplifies equipment management and maintenance and ensures that each device has a dedicated connection method. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Please see Figure 1-14 This embodiment proposes a thin plug with a foolproof structure, including a socket 1, and further including: Two first limiting blocks 12 are symmetrically and fixedly connected to both sides of the inner wall of the socket 1; The adapter post 3 is rotatably connected to the inside of the socket 1; Two first limiting grooves 32 are symmetrically opened on both sides of the outer wall of the middle section of the transition column 3, and the opening angle is ninety degrees, so that the first limiting block 12 can rotate ninety degrees within the first limiting groove 32. Two second limiting rods 31 are symmetrically and fixedly connected to the inner sidewall of the first limiting groove 32; Two sets of four limiting components are symmetrically arranged on both sides of the inner bottom wall and the bottom inner wall of the socket 1, respectively. The two sets of limiting components cooperate with each other to limit the angle between the socket 1 and the adapter post 3. Card slot 33 is located in the middle section of the top wall of adapter post 3; Two first slots 34 are symmetrically opened on both sides of the inner middle section of the adapter post 3; The first magnet 35 is fixedly connected to the inner side of the middle section of the top wall of the adapter post 3; Two sets of four fixing plates 5 are symmetrically arranged on both sides of the top inner wall of the adapter column 3; A sealing assembly is disposed on the outer wall of the opposite side of the fixed plate 5; The limiting sleeve 51 is fixedly connected to the outer wall of the opposite side of the fixing plate 5; Rotating shaft 52 is rotatably connected to the inner side of limiting sleeve 51; Two angle limiting components are symmetrically arranged on the outer sides of both ends of the rotating shaft 52, and are used to adjust the angle of the fixing plate 5 and the sealing component; The connecting components are located on both sides of the bottom of the adapter post 3, and their top connecting ends are located on the inner side wall of the bottom of the slot 33. The sealing shell 6 is slidably connected to the inside of the slot 33; Three signal arrows 11 are respectively fixedly connected to one side of the top wall of socket 1, one side of the top wall of adapter post 3, and the bottom of the outer wall of one side of sealing shell 6; Two pins 7 are symmetrically and fixedly connected to the inside sides of the sealing shell 6; Two sets of second slots 62 are respectively opened on both sides of the bottom wall of the sealing shell 6 and are located on both sides of the pin 7; Three second limiting grooves 63 are formed on the inner side of the bottom of the sealing shell 6; A magnetic suction component is disposed inside the second limiting groove 63; Two fixed cylinders 8 are symmetrically fixedly connected to the inside sides of the fixed cylinder 8; The first power-connecting copper plate 71 is fixedly connected to the inner side of the bottom of the fixed cylinder 8; The second power-connecting copper plate 72 is fixedly connected to the inner side of the top of the fixed cylinder 8; The power connection component is located inside the fixed cylinder 8 and, in cooperation with the magnetic attraction component, controls the connection between the first power connection copper plate 71 and the second power connection copper plate 72. A wire end fixing component is located at the top of the fixing cylinder 8 and is used to fix the end of the external wire. The partition plate 61 is fixedly connected to the middle section of the bottom wall inside the sealing shell 6.

[0022] like Figure 1-14As shown, in a preferred embodiment, based on the above method, the limiting component further includes first sliding grooves 2 respectively opened on both sides of the bottom wall of the socket 1 and the bottom wall of the adapter post 3. A first spring 21 is fixedly connected to the inner wall of the first sliding groove 2 on the side away from each other. A second limiting block 22 is fixedly connected to the opposite end of the first spring 21 and slidably connected to the inner side of the first sliding groove 2. A first limiting rod 23 is fixedly connected to the side wall of the second limiting block 22 on the side away from each other. The first spring 21 pushes the second limiting block 22 to move towards the second limiting block 22 with the inner wall of the first sliding groove 2 as the stress point. At the same time, the second limiting block 22 drives the first limiting rod 23 to move synchronously. When the plug 7 is not inserted into the inner side of the first slot 34, the top end of the first limiting rod 23 on the inner side of the socket 1 is inserted into the bottom end of the first slot 34, limiting the angle between the socket 1 and the adapter post 3, so that the adapter post 3 cannot rotate in the socket 1 to conduct electricity. At the same time, the first limiting rod 23 itself is an insulating material and will not conduct electricity.

[0023] like Figure 6-9 As shown, the sealing assembly includes a connecting frame 53 symmetrically rotatably connected to the outer walls on both sides of the rotating shaft 52. A sealing plate 54 is fixedly connected to the outer wall of the connecting frame 53 away from the fixed plate 5. The fixed plate 5 and the sealing plate 54 are connected by the connecting frame 53 through the rotating shaft 52. A second sliding groove 55 is provided on the top wall of one side of the sealing plate 54. A rack 56 is fixedly connected to the side wall of the second sliding groove 55. The rack 56 is supported and fixed by the second sliding groove 55. The rack 56 is only provided on one side, so that when the pin 7 is inserted at a specific angle, the rack 56 and the magnetic assembly can be connected, and the magnetic assembly can be driven to operate.

[0024] like Figure 8-9 As shown, the angle limiting assembly includes a fixed sleeve 57 fixedly connected to the outer wall of the connecting frame 53 on the side away from each other, a stress spring 58 rotatably connected to the outer walls of both ends of the rotating shaft 52, and a stress rod 59 fixedly connected to the outer wall of the fixed plate 5 on the opposite side. One end of the stress spring 58 is fixedly connected to the end of the fixed sleeve 57, and the other end of the stress spring 58 is fixedly connected to the end of the stress rod 59. The stress spring 58 drives the end of the fixed sleeve 57 to rotate upward with the stress rod 59 as the stress point. Thus, when the pin 7 is inserted, the bottoms of the corresponding sealing plates 54 on both sides are in contact with each other, realizing waterproofing and dustproofing of the inner side of the first slot 34.

[0025] like Figure 4-10As shown, the connecting assembly includes a second connecting line 4 symmetrically fixedly connected to both sides of the bottom of the adapter post 3. The adapter post 3 supports and fixes the second connecting line 4. A connecting post 41 is slidably connected to the inner side of the second connecting line 4. A graphite brush 42 is fixedly connected to the bottom wall of the connecting post 41. A second spring 43 is fixedly connected to the top wall of the graphite brush 42. The top of the second spring 43 is fixedly connected to the inner wall of the second connecting line 4. The top end of the second connecting line 4 is fixedly connected to the inner wall of the slot 33. The second spring 43 pushes the graphite brush 42 to the bottom with the inner wall of the second connecting line 4 as the stress point, so that the graphite brush 42 always fits against the inner bottom wall of the socket 1. Thus, after rotation, the stable connection between the second connecting line 4 and the first connecting line 13 can be ensured.

[0026] like Figure 10-12 As shown, the magnetic suction assembly includes a second magnet 66 rotatably connected to the inner side of the second limiting groove 63. A support shaft 64 is fixedly connected to the inner side of the second magnet 66. A gear 65 is fixedly connected to the end of the support shaft 64 away from the second magnet 66. The support shaft 64 is supported by the side wall of the sealing shell 6. At the same time, the gear 65 and the second magnet 66 are supported and fixed by the support shaft 64. The gear 65 is meshed with the rack 56. During the insertion process through the pin 7, the rack 56 drives the gear 65 and the second magnet 66 to rotate, thereby flipping the second magnet 66.

[0027] like Figure 12 As shown, the power-connecting assembly includes a third slide groove 81 located inside the fixed cylinder 8. Two slide rods 82 are fixedly connected to both sides inside the third slide groove 81. A third magnet 83 is slidably connected to the outer side of the middle section of the slide rods 82. A sliding copper frame 84 is fixedly connected to the top wall of the third magnet 83. The sliding copper frame 84 is slidably connected to the slide rods 82. After the second magnet 66 is flipped, the top of the second magnet 66 and the bottom of the third magnet 83 are of the same pole, thus repelling each other. This pushes the sliding copper frame 84 upward, connecting the first power-connecting copper plate 71 and the second power-connecting copper plate 72. When the second magnet 66 is not flipped, the top of the second magnet 66 and the bottom of the third magnet 83 are of opposite poles, attracting each other. This attracts the third magnet 83, keeping it fixed at the bottom of the third slide groove 81, disconnecting the first power-connecting copper plate 71 and the second power-connecting copper plate 72. Even if the plug 7 is inserted into another socket, it cannot be powered.

[0028] like Figure 14 As shown, the wire end fixing assembly includes a fixing copper post 73 fixedly connected to the top wall of the fixing cylinder 8. A fixing bolt 74 is threadedly connected to the inner side of the top of the fixing copper post 73. The fixing bolt 74 clamps and fixes the wire inserted into the fixing copper post 73.

[0029] like Figure 1-13As shown, the sealing shell 6 is composed of two side walls, and one side wall is connected to the partition plate 61 by screws. The partition plate 61 separates the first power-connecting copper plate 71 and the second power-connecting copper plate 72 on both sides.

[0030] like Figure 3 As shown, when the second connecting line 4 is not electrically connected to the first connecting line 13, the bottom first limiting rod 23 limits the angle of the adapter post 3 and the socket 1 by inserting into the inner side of the bottom of the first slot 34.

[0031] Specifically, when using this AAA: First, align the signal arrow 11 on the side wall of the sealing shell 6 with the signal arrow 11 on the top of the adapter post 3, and insert the pin 7 into the inside of the sealing plate 54. Then, insert the pin 7 into the first slot 34. During the process, the pin 7 first supports the corresponding sealing plates 54 on both sides, causing the sealing plates 54 to rotate and fit against the side wall of the pin 7. As the pin 7 is gradually inserted into the first slot 34, the rack 56 and the gear 65 come into contact and mesh with each other. As the pin 7 is inserted, it drives the second magnet 66 to flip. After the pin 7 is fully inserted into the inside of the first slot 34, the second magnet 66 rotates exactly 180 degrees and flips over. After the second magnet 66 is flipped over, the top of the second magnet 66 and the bottom of the third magnet 83 are the same pole, thus pushing the third magnet 83 to the top. The sliding copper frame 84 connects the first power-connecting copper plate 71 and the second power-connecting copper plate 72, thereby connecting the wires in the fixed copper column 73 to the plug 7. When the pin 7 contacts the first limiting rod 23 inside the adapter post 3, it will press the first limiting rod 23 down to the bottom. The first limiting rod 23 inside the adapter post 3 will press down the first limiting rod 23 inside the socket 1, push the first limiting rod 23 inside the socket 1 out of the first slot 34, cancel the restriction between the socket 1 and the adapter post 3, and allow the adapter post 3 to rotate inside the socket 1. After the pin 7 is fully inserted into the first slot 34, rotate the adapter post 3 to align the adapter post 3 with the signal arrow 11 on the top of the socket 1. Power can only be applied after all three signal arrows 11 are aligned. In case of a short circuit, the pin 7 can be directly pulled out of the first slot 34 without having to rotate the adapter post 3, thereby improving the safety of the device.
