[0033] refer to Figures 1-3This embodiment provides a power cord plug anti-detachment protection device, mainly used in smart sockets, but also compatible with other ordinary sockets. The power cord plug anti-detachment protection device includes a socket 1 for plugging in a power cord and a protective device 2 detachably connected to the socket 1. The protective device 2 is used to restrict the power cord plug to the socket 1 after it is plugged in. The socket 1 has a first connecting structure on its insertion surface 11, which is the end face for plugging in the power cord. The protective device 2 has a second connecting structure on its back side. The first connecting structure and the second connecting structure are slidably connected. The socket 1 has a first locking member on its insertion surface 11, and the protective device 2 has a second locking member on its back side. When the first locking member and the second locking member are interlocked, the sliding of the first connecting structure and the second connecting structure is restricted, and the protective device 2 is fixed to the socket 1. The first locking member includes an unlocking member, which is used to release the interlocking state between the first locking member and the second locking member.

[0034] The socket 1 and the protective device 2 are detachably connected via a sliding connection between the first and second connecting structures, facilitating the installation and removal of the protective device 2. When the first locking member and the second locking member interlock, the sliding between the first and second connecting structures is restricted, thereby fixing the protective device 2 to the socket 1 and ensuring that the protective device 2 will not easily loosen or shift during use, thus firmly securing the power cord plug. The unlocking member is used to release the interlock, allowing for quick removal of the protective device 2 when needed.

[0035] The first and second connecting structures are as follows: the first connecting structure is a groove 12 arranged along the length of the insertion surface 11, and the second connecting structure is a slide rail 21 arranged along the length of the back side of the protective device 2; the length of the groove 12 is less than the length of the insertion surface 11, the length of the slide rail 21 is less than the length of the back side of the protective device 2, and the length of the groove 12 is equal to the length of the slide rail 21; the groove 12 is provided with a sliding inlet 13, and the slide rail 21 slides into the groove 12 through the sliding inlet 13.

[0036] The cooperation between the slide groove 12 and the slide rail 21 allows the protective device 2 to slide smoothly onto the socket 1 along the direction of the slide groove 12, achieving connection and positioning between the two. The simple structural cooperation between the slide groove 12 and the slide rail 21 makes it easy to process and implement, and the design of the sliding entrance 13 ensures a stable connection and smooth sliding between the protective device 2 and the socket 1.

[0037] The sliding grooves 12 are configured in two sets, with the two sets of sliding grooves 12 arranged on both sides along the width direction of the insertion surface 11; the slide rails 21 are configured in two sets corresponding to the sliding grooves 12, with the two sets of slide rails 21 arranged on both sides along the width direction of the back of the protective device 2. By setting two sets of sliding grooves 12 and two sets of slide rails 21, the connection stability between the protective device 2 and the socket 1 is enhanced, making the force more even and better able to resist the pulling of external forces on the power cord plug, further improving the effect of preventing the power cord plug from falling off.

[0038] During installation, the slide rails 21 on both sides of the protective device 2 need to be aligned with the sliding grooves 12 and inlets 13 on both sides of the socket 1, respectively. Then, the protective device 2 is pushed simultaneously, causing the slide rails 21 on both sides to slide along the corresponding sliding grooves 12 until the protective device 2 reaches the appropriate position, completing the initial connection and achieving a stable connection. This double slide rail 21 structure design can better distribute the force when subjected to stress, reducing the risk of connection failure due to excessive local stress.

[0039] Both the slide groove 12 and the slide rail 21 have trapezoidal cross-sections, making the slide rail 21 more stable when sliding within the slide groove 12 and less prone to detachment. This further enhances the connection between the protective device 2 and the socket 1, improves the device's anti-interference capability and reliability, and effectively prevents the protective device 2 from separating from the socket 1 due to external impact or vibration, thus ensuring that the power cord plug is always protected. Simultaneously, the trapezoidal cross-section structure provides guidance and limitation, ensuring that the slide rail 21 can smoothly slide into the slide groove 12 and maintain a stable connection.

[0040] The first and second locking components are specifically designed as follows: the first locking component includes a miniature electromagnetic lock 14, and the second locking component includes a keyhole 22. The lock cylinder 15 of the miniature electromagnetic lock 14 is retractable and can cooperate with the keyhole 22 to lock or unlock. By using the miniature electromagnetic lock 14 and the keyhole 22 as locking components, the power cord plug anti-detachment protection device achieves automated and intelligent control. The retractable lock cylinder 15 of the miniature electromagnetic lock cooperates with the keyhole 22 to lock or unlock, enabling quick and accurate fixing and releasing between the protective device 2 and the socket 1. This improves the convenience and efficiency of operation, while also enhancing the safety and reliability of the device.

[0041] The first locking element includes a Hall sensor 16, and the second locking element includes a sensing magnet 23. The Hall sensor 16 is electrically connected to the miniature electromagnetic lock 14. The addition of the Hall sensor 16 and the sensing magnet 23 enables automated locking control. When the first and second connecting structures slide to a designated position, the miniature electromagnetic lock 14 aligns with the keyhole 22. The sensing magnet 23 triggers the Hall sensor 16, which then sends feedback to the miniature electromagnetic lock 14. The lock cylinder 15 of the miniature electromagnetic lock extends and engages with the keyhole 22 to lock.

[0042] The unlocking mechanism includes a button 17, which is located on one side of the socket 1, excluding the insertion surface 11. The button 17 is electrically connected to the miniature electromagnetic lock 14, and controls the retraction of the lock cylinder 15 of the miniature electromagnetic lock via the button 17. The user only needs to press the button 17 to control the retraction of the lock cylinder 15 of the miniature electromagnetic lock, thus unlocking the device. The operation is simple, quick, and easy to master.

[0043] The protective device 2 includes a chamber 24 for inserting the power cord plug, and a first opening 25 and a second opening 26 disposed on the front and back of the protective device 2, respectively. The first opening 25 and the second opening 26 are two U-shaped openings arranged opposite each other. The width of the first opening 25 is adapted to the width of the power cord plug, and the power cord plug is confined within the chamber 24 by the first opening 25. An insertion port 27 is provided on the upper end face of the protective device 2, and the first opening 25, the second opening 26 and the insertion port 27 are connected. The power cord plug is inserted into the chamber 24 through the insertion port 27, and the wire connected to the power cord plug extends out through the first opening 25. The second opening 26 is used to allow the power cord plug to be inserted into the socket 1. This structural design provides a space for the power cord plug, ensuring that the power cord plug can be smoothly inserted and stably placed in the chamber 24 during the plugging process. At the same time, the design of the first opening 25 and the second opening 26 facilitates the extension of the cord and provides space for the plug and socket 1 to be plugged in, ensuring that the plug and socket 1 can be connected normally. This further improves the overall structure and function of the power cord plug anti-drop protection device and enhances the practicality and reliability of the device.

[0044] When using this power cord plug anti-detachment protection device, after the power cord plug is inserted into the socket 1, the protective device 2 is installed on the socket 1. During installation, the slide rails 21 on both sides of the protective device 2 are aligned with the sliding grooves 12 and sliding entrances 13 on both sides of the socket 1, and the insertion port 27 of the protective device 2 is aligned with the position of the power cord plug. Then, the protective device 2 is pushed at the same time, so that the slide rails 21 on both sides slide along the corresponding sliding grooves 12 until the slide rails 21 are completely slid into the sliding grooves 12. The protective device 2 reaches the appropriate position and completes the initial connection. During the sliding process, the power cord plug is inserted from the insertion port 27 of the protective device 2 and enters the chamber 24. The wire is routed through the first opening 25, and the chamber 24 protects the power cord plug, preventing the power cord plug from coming out of the first opening 25.

[0045] After the protective device 2 slides to the designated position, the lock cylinder 15 of the miniature electromagnetic lock 14 aligns with the keyhole 22. The sensing magnet 23 triggers the Hall sensor 16, which sends feedback to the miniature electromagnetic lock 14, causing the lock cylinder 15 to automatically extend and engage with the keyhole 22 to lock, thus fixing the protective device 2 to the socket 1. This fixation of the protective device 2 to the socket 1 also secures the power cord plug, preventing it from detaching. When it is necessary to remove the protective device 2, press the button 17 located on the side of the socket 1. The button 17, through electrical connection, controls the lock cylinder 15 of the miniature electromagnetic lock 14 to retract, releasing the lock. Then, the protective device 2 can be slid to remove it from the socket 1.

[0046] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
