The terminology used in the description of embodiments in this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Examples, such as Figure 1 As shown, this application provides an active data destruction device based on a Hall sensor, the destruction device comprising: Multifunctional pin socket 1, such as Figure 2 As shown, a circular PCB board 101 is provided inside the multifunctional pin socket 1, and a Hall sensor 1011 is designed on the upper part of the circular PCB board 101.

[0023] Specifically, the multi-functional pin socket 1 contains a circular PCB board 101, which is the core component for electrical control and is used to mount the Hall sensor 1011 and its peripheral circuitry. The Hall sensor 1011 is a magnetically sensitive switching element based on the Hall effect, where a Hall voltage proportional to the magnetic induction intensity is generated when a conductor or semiconductor fluid is subjected to a perpendicular magnetic field. By placing the Hall sensor 1011 on the upper part of the PCB board, the magnetic field change generated by the strip permanent magnet can be accurately detected when the pull ring pin is inserted or removed, thereby achieving real-time identification of the pin state and circuit logic switching. This placement shortens the magnetic induction path and improves detection sensitivity, while also facilitating the layout and soldering of other electronic components on the PCB board, such as amplifier circuits and control logic modules, ensuring good electromagnetic compatibility and anti-interference capabilities for the entire sensing circuit. The circular PCB board 101, mechanically fixed to the permalloy cylinder, achieves structural and functional integration, ensuring stable operation of the Hall sensor even under vibration, impact, or high / low temperature changes, thus providing a reliable signal input basis for the device's active data destruction function.

[0024] Pull ring pin 2, such as Figure 3 As shown, the pull ring pin 2 is fixed inside the multifunctional pin female seat 1, and the pull ring pin 2 is embedded with a strip-shaped permanent magnet 201.

[0025] Specifically, the pull ring pin 2 is a pluggable actuator of the device, primarily serving a dual function of mechanical locking and magnetic field triggering. In its assembled state, the pull ring pin 2 is fixed inside the multi-functional pin socket 1, using a steel ball locking structure to achieve insertion / removal positioning and retaining force control, thereby ensuring a stable mechanical connection even in vibration or impact environments. A strip-shaped permanent magnet 201 is embedded in the front end of the pull ring pin 2. This permanent magnet is a stable magnetic field element, its main function being to provide a constant magnetic flux to the Hall sensor inside the socket. When the pull ring pin is inserted, the magnetic field of the permanent magnet 201 acts on the Hall sensor on the socket PCB board, keeping its output in an open circuit state, and the system continues to operate. When the pull ring pin is pulled out, the magnetic field disappears, the Hall sensor switches to a closed state, thereby triggering the data destruction circuit. The strip-shaped permanent magnet 201 adopts a long-axis structure, which enhances the stability of the magnetic induction direction and facilitates the linear change of the magnetic flux line during insertion and removal, improving the response accuracy of the Hall sensor. The overall structure, through the metal shielding and material matching design of the latch shell, takes into account both mechanical strength and electromagnetic stability, and can realize the active data destruction function that can still be reliably triggered in extreme environments.

[0026] When the pull ring pin 2 is inserted into the multifunctional pin socket 1, the Hall sensor 1011 senses the strip permanent magnet 201, the Hall switch is open, the circuit is broken, the equipment operates normally, and the data resources are not destroyed; when the pull ring pin 2 is pulled out of the multifunctional pin socket 1, the Hall sensor 1011 does not sense the strip permanent magnet 201, the Hall switch is closed, the circuit is connected, the equipment stops operating, and the data resources are actively destroyed.

[0027] Optionally, when the pull ring pin 2 is inserted into the multi-functional pin socket 1, the Hall sensor 1011 mounted on the circular PCB board 101 is within the effective magnetic field sensing area and can detect the stable magnetic flux density generated by the strip permanent magnet 201. The Hall sensor 1011 outputs a corresponding level signal according to the presence of the magnetic field, keeping the Hall switch in the open circuit state, connecting the operation path and disconnecting the destruction path, maintaining normal operation of the equipment, keeping data resources in a safe storage state, and not executing the destruction logic.

[0028] Conversely, when the pull ring pin 2 is pulled out from the multi-functional pin socket 1, the Hall sensor 1011 is removed from the magnetic field of the permanent magnet 201, and its sensing signal quickly decays to below the threshold, making it unable to continue sensing the magnetic field signal. The Hall switch closes, triggering the control circuit to disconnect the operation path and connect the destruction path. The equipment operation stops immediately and the active data destruction program is started, thereby stopping the equipment operation immediately and actively and completely destroying the stored key data.

[0029] This design utilizes the highly sensitive response of the Hall sensor 1011 to the presence or absence of a magnetic field, directly converting physical plugging and unplugging behavior into electrical signal logic, thus realizing a hardware-level security protection mechanism. This mechanism has advantages such as fast response speed, strong anti-interference, and no mechanical contact wear, ensuring that the data protection and destruction process can still be accurately completed under sudden unplugging, strong magnetic interference, or extreme environmental conditions.

[0030] Furthermore, the multifunctional pin socket 1 also includes a permalloy cylinder 102, the rear end of which is inserted into the circular PCB board 101 to fix the circular PCB board 101, and the permalloy cylinder 102 is machined with inner holes of different diameters to match the diameter structure of the pull ring pin 2.

[0031] It should be understood that the multifunctional pin socket 1 contains a permalloy cylinder 102, which serves as the core component for magnetic shielding and structural support of the device. Permalloy is a soft magnetic alloy material with high permeability and low coercivity, possessing excellent magnetic flux focusing and shielding performance, which can effectively reduce the interference of external magnetic fields on the Hall sensor 1011. A circular PCB board 101 is mounted at the rear end of the permalloy cylinder 102, achieving tight assembly through mechanical pressing or threaded fixing. This not only serves to fix the PCB board but also ensures the continuity of the magnetic circuit, forming a stable and controllable magnetic flux distribution path in the area where the Hall sensor is located.

[0032] Furthermore, the permalloy cylinder 102 employs a graded turning structure design internally, meaning its inner bore is machined into two or more different diameters along the axial direction to accommodate different sized pin segments in the pull ring pin 2. This design ensures precise positioning and guidance of the pin during insertion, maintaining a constant relative position between the permanent magnet 201 and the Hall sensor 1011. Additionally, by controlling the gap between different diameter segments, insertion / removal damping and sealing performance can be effectively adjusted, preventing dust or impurities from entering the internal structure. Thus, the permalloy cylinder 102 provides mechanical support while also offering electromagnetic shielding and magnetic flux control functions, making it a key component ensuring the stable and reliable operation of the device described in this application.

[0033] Furthermore, the multifunctional pin socket 1 also includes a permalloy circular back cover 103, which is located at the rear end of the circular PCB board 101, so that the permalloy cylinder 102 forms a closed magnetic loop.

[0034] Specifically, the multifunctional pin socket 1 also includes a permalloy circular back cover 103, which is mounted on the rear end of the circular PCB board 101 and fits against the rear end face of the permalloy cylinder 102, thus forming a continuous and closed magnetic loop system. This design utilizes the high permeability of permalloy material to allow magnetic flux to form a complete magnetic flux loop between the cylinder 102 and the circular back cover 103, significantly improving the convergence and stability of the magnetic field and preventing magnetic flux leakage or external magnetic interference from entering the sensing area. Through this closed magnetic loop, the operating magnetic field of the Hall sensor 1011 is confined within a preset spatial range, ensuring the repeatability and reliability of the sensed signal.

[0035] Furthermore, the permalloy circular back cover 103 serves both mechanical protection and electromagnetic shielding functions. Firstly, through its tight assembly with the cylinder 102, the back cover provides structural support and protection for the circular PCB board 101, preventing displacement or deformation under vibration, impact, or other conditions. Secondly, the back cover further reduces the influence of strong external magnetic fields or electromagnetic radiation on the Hall sensor, thereby ensuring that the device can still accurately identify the insertion / removal status and stably execute data destruction logic even in complex electromagnetic environments. This structure not only enhances the integrity of the overall magnetic circuit closure but also makes this application superior to traditional open magnetic circuit designs in terms of both safety and reliability.

[0036] Furthermore, the multifunctional plug socket 1 also includes a destruction device housing 104, which is used to enclose the permalloy cylinder 102 to prevent it from affecting the external circuit.

[0037] Optionally, the multi-functional plug socket 1 also includes a destruction device housing 104, which is disposed around the periphery of the permalloy cylinder 102 to physically encapsulate and electromagnetically isolate the entire magnetic induction structure. This housing is made of high-strength conductive metal or an alloy material with electromagnetic shielding properties, and its main function is to prevent magnetic flux leakage generated by the permalloy cylinder 102 when forming a magnetic loop from causing unnecessary interference to surrounding circuits or components.

[0038] In this application, the permalloy cylinder 102 has a high internal magnetic flux density. Without effective shielding, external sensitive circuits may be subject to induced interference, leading to signal distortion or false triggering. By enclosing the device with the housing 104, the entire magnetic induction area can be formed into a closed electromagnetic cavity, effectively suppressing magnetic field diffusion and improving the system's electromagnetic compatibility (EMC). In addition, the housing also provides structural support and protection, resisting external mechanical impacts, dust, and moisture corrosion of internal components, thus extending the device's service life.

[0039] In summary, the outer shell 104 of the destruction device is not only a mechanical protective structure, but also an electromagnetic safety barrier. Together with the permalloy cylinder 102 and the permalloy circular back cover 103, it forms a multi-layer protection system, providing a stable working environment for the Hall sensor 1011 and ensuring that the device can reliably and accurately perform the data destruction control function even in complex electromagnetic and physical environments.

[0040] Furthermore, the multifunctional pin female seat 1 is a cylindrical metal structural component containing a steel ball buckle 105 for engaging with the groove of the pull ring pin 2 to fix the pull ring pin 2 inside the multifunctional pin female seat 1.

[0041] In one possible embodiment of this application, the multifunctional pin seat 1 is a cylindrical metal structure with a steel ball latch 105 inside. This latch, composed of a steel ball and a columnar spring 1051, engages with a groove on the outer surface of the pull ring pin 2 to achieve mechanical locking and positioning of the pin. Specifically, the steel ball latch 105 is installed in a groove in the inner wall of the seat 1, and the columnar spring 1051 is located behind the steel ball, providing radial elastic preload so that the steel ball partially protrudes from the inner wall surface of the seat when stationary. When the pull ring pin 2 is inserted into the seat 1, the groove on the pin surface gradually compresses the spring 1051, and the steel ball automatically resets and embeds itself in the groove, achieving precise axial limiting and radial positioning.

[0042] This structural design ensures smooth insertion and removal while providing a stable holding force, preventing the pull ring pin 2 from loosening due to vibration or external force, thereby ensuring that the relative position between the Hall sensor 1011 and the strip permanent magnet 201 remains constant and avoiding false triggering or signal loss.

[0043] Furthermore, the elastic connection feature of the steel ball latch 105 enables self-locking and self-resetting during the insertion and removal of the pin, eliminating the need for additional mechanical fastening structures and thus improving assembly convenience and reliability. The steel ball and spring assembly, made of high-hardness stainless steel or nickel-plated alloy, is heat-resistant, corrosion-resistant, and adaptable to complex environmental conditions. This latching mechanism ensures precise positioning while providing long-term stable mechanical performance for repeated insertion and removal of the device, making it one of the key supporting components for achieving high-reliability physical trigger control in this application.

[0044] Furthermore, the pull ring pin 2 is a cylindrical metal structural component, and also includes: A pin structure 202 is located at one end of the pull ring pin 2. Its upper end is a cylindrical structure with a first diameter and a second diameter, and its lower end is designed as a stud. A pull ring structure 203 is located at the other end of the pull ring pin 2. Its upper end is a nut 2031, which can be screwed into the stud.

[0045] Specifically, the pull ring pin 2 is a cylindrical metal structural component, which adopts a split assembly structure, including two parts: the pin structure 202 and the pull ring structure 203. The pin structure 202, located at one end of the pull ring pin 2, is the main part for mechanical insertion and magnetic field transmission. Its upper end is designed as a double-section cylindrical structure with a first diameter and a second diameter. The first diameter section is used for precise guiding and engagement with the inner hole of the multi-functional pin socket 1, ensuring the coaxiality and stability of the insertion path; the second diameter section cooperates with the steel ball latch 105 inside the socket, providing mechanical limiting and locking functions to prevent the pin from loosening due to vibration during operation. The lower end of the pin structure 202 is designed as a stud, allowing for detachable assembly with the pull ring structure 203 via a threaded connection, facilitating later maintenance and replacement.

[0046] The pull ring structure 203 is located at the other end of the pull ring pin 2 and is an external component operated by the user. Its upper end is equipped with a nut 2031 for tightening with the stud end of the pin structure 202, thus forming a mechanically closed integral structure. The pull ring structure 203 has an annular operating element on its exterior for easy manual insertion and removal. Through this structural design, the pull ring pin 2 not only achieves modularity and maintainability but also ensures mechanical stability and magnetic field sensing accuracy in the inserted state. The threaded connection effectively avoids assembly errors caused by welding or riveting and has good anti-vibration and loosening performance, ensuring that the fixed magnetic induction relationship between the Hall sensor 1011 and the strip permanent magnet 201 is maintained even in complex environments.

[0047] Furthermore, the pin structure 202 is made of permalloy or cast iron. The pull ring structure 203 is made of non-magnetic aluminum alloy.

[0048] It should be understood that the pin structure 202 is made of permalloy or cast iron to balance the requirements of mechanical strength and magnetic performance. Permalloy, as a soft magnetic material with high permeability, can effectively guide and concentrate the magnetic flux generated by the strip permanent magnet 201, making the magnetic induction path stable and directional, thereby improving the sensing sensitivity and signal stability of the Hall sensor 1011. When cast iron is used, its high mechanical strength and machinability can be utilized to ensure that the pin structure maintains its shape stability under frequent insertion and removal and external impact, without plastic deformation or breakage. The selection of either material achieves a balance between structural rigidity and magnetic flux guiding performance, suitable for applications with different strength and magnetic shielding requirements.

[0049] The pull ring structure 203 is made of non-magnetic aluminum alloy, primarily to eliminate magnetic field interference and reduce overall weight. Since the pull ring structure 203 is located at the external operating end of the pull ring pin 2 and does not participate in magnetic flux conduction, using magnetic materials would potentially cause magnetic field distortion or Hall sensor sensing errors. Aluminum alloy not only possesses excellent mechanical strength and corrosion resistance but also exhibits good non-magnetic characteristics, effectively maintaining the uniformity of the magnetic field distribution. Furthermore, the lightweight nature of aluminum alloy makes pull ring operation more flexible, reducing the inertial load during insertion and removal. Through the functional zoning design of the aforementioned materials, the pin structure 202 and pull ring structure 203 complement each other in terms of structural mechanics and electromagnetic performance, enabling the device to maintain high reliability and long-term stability while preserving magnetic induction accuracy.

[0050] Furthermore, the lower end of the pull ring structure 203 is a destroy pull ring 2031, used to insert or pull out the pull ring pin 2.

[0051] Optionally, the lower end of the pull ring structure 203 is provided with a destruction pull ring 2031. This destruction pull ring 2031 is a manually operated component of the device, used to control the insertion and removal of the pull ring pin 2. The destruction pull ring 2031 can adopt a ring-shaped or semi-ring-shaped metal structure, and is integrally formed with the body of the pull ring structure 203 through integral casting or mechanical connection. The setting of this component allows the user to quickly perform a physical removal action in an emergency, thereby triggering the data destruction process.

[0052] Functionally, the 2031 release ring not only serves as the operating interface, but its size, shape, and mechanical design have also been optimized to meet ergonomic and safe triggering requirements. The ring features rounded edges and a thickened cross-section, providing sufficient grip and tensile strength during operation to prevent structural breakage due to stress concentration. In terms of materials, non-magnetic aluminum alloy or high-strength stainless steel can be selected, ensuring non-magnetic properties to avoid interference with the magnetic field sensed by the Hall sensor 1011, while also possessing good mechanical durability and environmental adaptability.

[0053] When the user pulls the destruction ring 2031, the ring pin 2 disengages from the internal structure of the multi-functional pin socket 1, instantly releasing the magnetic field coupling between the strip permanent magnet 201 and the Hall sensor 1011. The Hall sensor output changes, and the system immediately enters the destruction logic execution phase, achieving proactive and irreversible data destruction triggering. This allows for direct integration with electrical control logic at the mechanical operation level, providing the system with a fast, reliable, and manually controllable hardware-level safety protection method.

[0054] In summary, the apparatus provided in this application has at least the following technical effects or advantages: This application provides an active data destruction device based on a Hall sensor. It achieves instant switching of circuit states through the magnetic induction relationship between the Hall sensor and a strip-shaped permanent magnet, rapidly triggering data destruction when the device is unplugged or abnormally disconnected, ensuring critical data is unrecoverable. A closed magnetic loop is formed using a permalloy cylinder and a circular back cover, with electromagnetic shielding provided by the outer shell, effectively preventing interference from strong external magnetic fields and malfunctions, ensuring stable operation even under complex environments such as vibration, impact, and extreme temperatures. A steel ball locking structure between the pull ring pin and the female connector ensures smooth insertion and removal and reliable locking. The use of magnetically conductive materials for the pin structure and non-magnetic aluminum alloy for the pull ring structure achieves a balance between mechanical strength and magnetic field stability. This design enables hardware-level data destruction without damaging the device, offering advantages such as active destruction and rapid response, high reliability and anti-interference, reasonable structure, and strong security, making it suitable for data protection scenarios in various high-security fields.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0056] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of the embodiments of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
