DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] With the rapid development of information technology and the digital transformation of the power industry, the power monitoring system, as a national key information infrastructure, is facing increasing cybersecurity challenges. In this context, the frequent occurrence of cybersecurity incidents has exposed obvious hidden dangers in the power system, especially in network devices. If the numerous interfaces are not blocked, they may become a breakthrough for network attackers to invade.

[0034] In view of the technical feature "physical blocking tool", a blocking device specifically for the serial port interface can be developed. The blocking tool can be a plastic or metal device with a buckle structure, which can tightly seal the serial port interface. This buckle design not only has good tightness, but also provides a convenient installation and disassembly method. The user only needs to simply fix the buckle on the interface without additional tools, which greatly improves the convenience and efficiency of use. In addition, the buckle design can effectively prevent illegal access, thereby improving the security of the system.

[0035] In a specific implementation, the designed physical blocking tool can have a variety of shapes to adapt to serial ports of different sizes and shapes, such as rectangular, circular and other special-shaped designs. Accordingly, this diverse design provides users with a wider range of applicability to cope with different types of network devices. Through these unique designs, the blocking tool can not only effectively block physical intrusions, but also reduce the risk of improper use of the interface.

[0036] In this way, the advantage of implementing this physical blocking tool is that its effectiveness and durability are significantly improved. Unlike existing traditional blocking methods such as labels and seals, cable buckles are not easily damaged by time and external environment, ensuring the durability of the blocking effect. At the same time, the blocking tool can be made of high temperature resistant, corrosion resistant and other characteristic materials to ensure its stability under various environmental conditions. When encountering external interference or harsh environment, the blocking tool can still play its protective function, provide effective safety protection for the power system, and reduce potential network security risks.

[0037] In summary, as the demand for network security protection in power monitoring systems increases, developing a physical blocking tool specifically for serial ports will not only fill the market gap, but also provide a new solution for network security in the power industry. At the same time, the popularization and application of this tool will effectively improve the safety of power equipment, thereby promoting the healthy and sustainable development of the power industry.

[0038] Based on this, see Figures 1 to 6 As shown, an embodiment of the present invention provides a serial port plugging tool, the serial port 20 is provided with a plug-in frame 23 and a connecting portion, the connecting portion is located on the inner side of the plug-in frame 23 and is used to connect to the cable, the serial port plugging tool includes a plugging piece 100 and an unlocking piece 200; the plugging piece 100 includes a plugging frame 110 and a fixing portion 120, the fixing portion 120 is connected to the plugging frame 110, the plugging frame 110 is detachably connected to the plug-in frame 23, when the plugging piece 100 is connected to the serial port 20, the outer surface of the plugging frame 110 is flush with the outer surface of the plug-in frame 23, the fixing portion 120 is plugged into and matched with the plug-in frame 23; the plugging frame 110 is provided with an unlocking hole 111; the unlocking piece 200 is detachably connected to the plugging piece 100, and the unlocking piece 200 is adapted to the unlocking hole 111 and is used to drive the plugging piece 100 to separate from the plug-in frame 23.

[0039] The plugging tool for serial port 20 of the present application effectively solves the problem of insufficient physical plugging means of serial port 20 interface in the prior art through innovative design. The durability and stability of existing physical plugging means such as labels and seals are affected by many factors and are easily damaged by external forces or lose their protective effect, causing network security risks. The plugging tool of the present invention adopts the structural design of the plugging frame 110 and the fixing part 120, which ensures the firm installation of the plugging piece 100 on the serial port 20, greatly improves the effectiveness and stability of physical plugging, and effectively isolates unauthorized access.

[0040] When the blocking tool of this embodiment is used, when the blocking piece 100 is connected to the plug-in frame 23, since the outer surface of the blocking frame 110 is flush with the outer surface of the plug-in frame 23, the blocking tool cannot be taken out of the plug-in frame 23 from the outside of the blocking piece 100, and the blocking piece 100 can be separated from the plug-in frame 23 only by connecting the unlocking piece 200 to the unlocking hole 111, which has high protection safety. Not only does it improve the security of the serial port 20, reduce the potential risk of network attacks, but it also provides great convenience for device management.

[0041] In the blocking tool for the serial port 20 of the present embodiment, the serial port 20 can be quickly blocked by arranging the blocking piece 100 and the unlocking piece 200. When the blocking piece 100 is connected to the serial port 20, the blocking piece 100 can be removed only through the unlocking piece 200. The structure is simple, the protection performance is good, and it is easy to use.

[0042] Specifically, the unlocking hole 111 includes a connecting hole portion 1111 and a limiting hole portion 1112. The structural design of the unlocking hole 111 includes the connecting hole portion 1111 and the limiting hole portion 1112, and the specific implementation method can be more efficiently applied in different scenarios. For example, the connecting hole portion 1111 can be designed to be circular, elliptical or polygonal to adapt to unlocking pieces 200 of different specifications. This design makes the unlocking tool more flexible in operation, helps to adapt to unlocking pieces of various models and sizes, reduces the user's operating difficulty and improves the compatibility of the device.

[0043] When optimizing the diameter design of the limiting hole 1112, multiple sizes can be selected according to the specific working environment to ensure that it can adapt to multiple unlocking tools. In this way, the adaptability of the unlocking hole 111 can be effectively improved, so that it can be smoothly matched with unlocking tools with different functions, thereby improving the universality and efficiency of the system.

[0044] The advantage of this structural design is also reflected in safety. Since the width of the limiting hole portion 1112 is greater than that of the connecting hole portion 1111, it is possible to prevent any external tool from entering the unlocking hole 111 through the limiting hole portion 1112. This foolproof design ensures that only certified unlocking tools can be operated, effectively preventing illegal access by outsiders, and significantly improving the safety of the blocking member 100.

[0045] In addition, during the unlocking process, after the unlocking member 200 enters through the connection hole 1111, the unlocking member 200 is rotated to cause misalignment with the unlocking hole 111. This operation design further enhances the stability of the connection. This arrangement not only helps to enhance the fixing effect of the unlocking member 200, but also improves the safety of the operation, ensuring that there will be no false touches or failures due to improper operation when trying to unlock.

[0046] To sum up, the design of the unlocking hole 111 not only optimizes the access process of the unlocking piece 200 and improves the overall operational convenience of the equipment through flexible shapes, diverse size options and protection against interference from external tools, but also significantly enhances safety and protection capabilities. It is an efficient and reliable technical solution.

[0047] In one embodiment, the number of the limiting holes 1112 is set to be multiple, and these multiple limiting holes 1112 are evenly distributed around the connecting hole 1111. This design allows the unlocking member 200 to access the unlocking hole 111 from different directions, thereby facilitating operation and improving convenience. This not only makes it easier for users to perform unlocking operations in actual use, but also greatly improves the protective effect of the blocking member 100.

[0048] Specifically, the configuration of the plurality of limiting holes 1112 enables the unlocking member 200 to be staggered with the limiting holes 1112, thereby driving the blocking member 100 to separate from the plug-in frame 23. This staggered design provides greater operational flexibility, making the unlocking process not only fast but also safe, and effectively avoiding potential risks caused by single-direction operation.

[0049] The advantage of this design is that the layout of the multiple limiting holes 1112 can effectively disperse the force applied to the unlocking member 200, reduce the impact of mechanical stress concentration on the blocking member 100, and improve the reliability and durability of the entire blocking device. When the unlocking member 200 applies force, the dispersed limiting holes 1112 help to reduce the pressure on a single point, thereby extending the service life of the entire device.

[0050] In addition, the design can provide compatibility for different types of unlocking tools, so that users can choose unlocking methods more flexibly without affecting the security of the system. Unlocking tools of different shapes and sizes can be effectively matched with multiple limit holes 1112, which greatly improves the adaptability and flexibility of the application, provides users with more choices, and thus meets the needs of different scenarios.

[0051] Specifically, there are two limiting holes 1112, and this symmetrical layout design effectively improves the overall stability of the unlocking hole 111. The symmetrical layout can ensure that the unlocking member 200 can be connected to the unlocking hole 111 in a 180° direction, so that the unlocking member 200 can maintain good supporting force and avoid failure or damage caused by uneven force application. This structure makes the overall device more reliable during use.

[0052] In a specific embodiment, the limiting hole 1112 can be designed in a variety of different shapes, such as circular, elliptical or polygonal. This variety of shapes allows the unlocking member 200 to enter the blocking frame 110 more smoothly, avoiding the jamming or resistance caused by improper edge design. At the same time, the diverse shapes also provide good compatibility for unlocking tools of different specifications and types, making it convenient for users to choose the appropriate unlocking tool according to specific needs.

[0053] In addition, to further improve safety, the edge of the limit hole 1112 can be designed to prevent slipping, such as by using special surface treatment or adding rubber pads. This design can effectively reduce the slipping of the unlocking member 200 during the unlocking process, ensuring that the user can stably control the unlocking tool when applying force, and reducing the operational risk caused by accidental slipping.

[0054] The design of double limit holes not only improves the connection strength of the device and strengthens the connection stability between the blocking piece 100 and the plug-in frame 23, but also provides a more flexible and convenient operation method for the unlocking process. This design helps users enjoy higher practicality and safety in actual operation, which in turn has a positive impact on the reliability of the entire device.

[0055] In one embodiment, the fixing portion 120 includes a buckle 121, which is protruding from the outer wall of the fixing portion 120 and is used to engage with the plug-in frame 23. Through this structural design, the buckle 121 not only provides an effective connection method, but also significantly enhances the stability of the connection and improves the reliability of the entire device during use. Compared with the traditional connection method, the use of the buckle 121 simplifies the assembly process and reduces the dependence on high-precision assembly tools, so that users can quickly and accurately complete the engagement during assembly, thereby improving work efficiency.

[0056] In a specific implementation, the buckle 121 can be designed in a variety of different shapes, such as a U-shape or a V-shape. This variety of shapes enables the buckle 121 to have higher compatibility in different usage situations and adapt to different types of plug-in frames 23. Especially when subjected to external force impact, this shape design can effectively absorb the impact force, prevent the buckle from loosening or falling off due to external factors, ensure the close fit between the components, and thus improve safety.

[0057] In terms of material selection, the buckle 121 can be made of high-strength plastic or metal. High-strength plastic is not only light but also has good impact resistance, while metal materials are excellent in durability and corrosion resistance. By properly selecting materials, not only the durability of the buckle 121 is enhanced, but also the corrosion resistance of the entire device in harsh environments is improved, ensuring its long-term stable and reliable operation.

[0058] The buckle 121 is arranged on the outer wall of the fixing part 120, so that the fixing reliability of the plugging member 100 is improved when it is connected to the serial port 20. At the same time, the convenience of the buckle 121 improves the efficiency of maintenance and replacement, so that when a fault occurs, the user can handle it more quickly, thereby improving the service life of the plugging tool.

[0059] In summary, the combination of the buckle 121 design and the fixing portion 120 brings many advantages of safety, reliability, and ease of operation and maintenance. This technical feature not only improves the overall performance of the blocking structure, but also helps to achieve a more efficient assembly and use experience, providing an effective solution for the optimized design of the device.

[0060] In one embodiment, the fixing portion 120 further includes an air-avoiding groove 122, which is provided through the outer wall of the fixing portion 120 and allows the fixing portion 120 to bend and deform inwardly along the direction of the air-avoiding groove 122 when subjected to an external force. By providing the air-avoiding groove 122 on the fixing portion 120, this design can not only reduce the weight of the structure to a certain extent, but also facilitate the fixing portion 120 to bend toward the inner side of the blocking pin 130 to be deformed when connected to the serial port 20.

[0061] In a specific implementation, the shape and depth of the air avoidance groove 122 can be flexibly adjusted according to the use requirements. For example, the air avoidance groove 122 can adopt a trapezoidal design to provide strong deformation adaptability and superior mechanical properties. The trapezoidal air avoidance groove can better disperse stress when deformed, thereby improving its overall impact resistance; while the arc design helps to provide uniform stress distribution when subjected to external impact, reducing the risk of damage caused by local stress concentration.

[0062] In terms of material selection, high-toughness plastic or metal alloy can be used to achieve the high performance requirements of the air avoidance groove 122. High-toughness plastic has excellent ductility and can effectively absorb impact energy to prevent fracture under harsh working conditions; metal alloy has excellent durability and corrosion resistance, so that the air avoidance groove 122 can still maintain a good deformation effect after long-term use. This material consideration not only extends the service life of the entire device, but also ensures its stability under high load conditions.

[0063] The implementation of this technical feature significantly improves the functionality of the fixing part 120, provides more design flexibility, improves assembly efficiency, and reduces the difficulty of maintenance and replacement. This design enhances the reliability of the entire device during use, allowing users to perform maintenance and operation more easily, and ultimately improves the overall performance and user experience of the blocking structure. In one embodiment, the extension direction of the air avoidance groove 122 is parallel to the connection direction between the blocking piece 100 and the serial port 20. At this time, when the blocking piece 100 is connected to the plug-in frame 23, the fixing part 120 can be bent toward the inner side of the air avoidance groove 122, so that the buckle 121 can be pressed against the inner wall of the plug-in frame 23 under the action of elasticity, so as to fix the blocking piece 100 and the plug-in frame 23, thereby improving the connection strength between the blocking piece 100 and the plug-in frame 23, thereby ensuring the blocking reliability of the blocking tool in this embodiment.

[0064] Furthermore, there are a plurality of the avoiding grooves 122 , and the plurality of avoiding grooves 122 are evenly and spaced apart around the fixing portion 120 .

[0065] In one embodiment, the fixing portion 120 further includes a plurality of air-avoiding grooves 122, which are uniformly and spaced around the outer wall of the fixing portion 120. This design not only improves the flexibility and stability of the fixing portion 120, but also can effectively cope with various external forces. The uniform distribution of the plurality of air-avoiding grooves 122 can well disperse the pressure applied to the fixing portion 120, reduce local stress concentration, and thus enhance the durability and anti-destruction ability of the overall structure.

[0066] In a specific implementation, the air avoidance groove 122 can be designed in a trapezoidal or arc shape. Such a shape can not only improve the deformation adaptability of the fixing part when subjected to external force, but also further improve its mechanical properties. In addition, the shape and depth of the air avoidance groove 122 can be adjusted according to actual application requirements, so that the fixing part 120 can perform optimal performance under different use environments. In terms of materials, high-toughness plastics or metal alloys can be selected to enhance the durability of the air avoidance groove 122 to ensure that the fixing part 120 can still maintain a good deformation effect after long-term use. This material selection helps to increase the service life of the entire device and adapt to the performance requirements under harsh working conditions.

[0067] In one embodiment, the plugging member 100 further includes a plugging pin 130, and the serial port 20 further includes a plugging hole 22. When the serial port 20 is connected to the serial port 20 by a plugging tool, the plugging pin 130 is plugged and matched with the plugging hole 22. This plugging method ensures a stable connection between the plugging member 100 and the serial port 20, and effectively prevents the plugging pin 130 from contacting the external environment, which not only improves the sealing performance of the connection, but also can reduce the protection risk caused by poor connection to a certain extent, so that the plugging member 100 can be applied to the serial port 20 of the female head.

[0068] Specifically, the blocking frame 110 further includes a lock buckle 112 , the fixing portion 120 is provided with a snap-fit ​​hole 123 , and the blocking pin 130 is disposed inside the fixing portion 120 .

[0069] When sealing, first connect the fixing part 120 with the plug-in frame 23, at which time the sealing pin 130 is plugged into the plug-in hole 22, and then the sealing frame 110 is clamped to the fixing part 120 through the lock 112 and the clamping hole 123 to complete the sealing.

[0070] To further enhance the applicability of the structure, the plugging pin 130 can be designed in a variety of shapes and sizes, such as round, rectangular or conical, to adapt to different specifications and types of plug holes 22. By adjusting the shape and size of the pin, better plugging effect and sealing performance can be achieved. In addition, the plugging pin 130 can be made of corrosion-resistant materials, such as high-strength plastic or stainless steel, to ensure long-term use in harsh environments. This material selection not only improves the durability of the plugging piece 100, but also ensures that the connection between the pin and the plug hole remains good in an environment of high temperature, humidity or chemical media.

[0071] In summary, the plug-in design between the sealing piece 100 and the serial port 20, combined with the sealing pins 130 of different shapes and materials, not only improves the sealing and stability of the device, but also provides flexible solutions for different application scenarios, ensuring reliable operation in dynamic and complex environments.

[0072] In another embodiment, the connection part further includes a connection pin 21, which is located inside the plug frame 23. When the serial port 20 is connected to the serial port 20 by a plugging tool, the fixing part 120 is arranged around the connection pin 21. In this way, the connection pin 21 not only serves as a key component of the connection, but its position setting also ensures accurate alignment during the connection process, reducing the probability of failure caused by improper assembly, so that the plugging piece 100 can be applied to the male serial port 20, and the fixing part 120 surrounds the connection pin 21 to protect the connection pin 21, avoiding motion interference when the plugging piece 100 is connected to the serial port 20.

[0073] In addition, the surrounding design of the fixing portion 120 improves the protection performance of the connecting pin 21 and reduces the wear and damage to the pin itself. This reasonable structural design not only ensures the functionality of the plugging piece 100, but also increases its reliability, adapts to the needs of different working environments, and further improves the overall quality and service life of the plugging tool.

[0074] Specifically, the unlocking member 200 is composed of an operating portion 210 and an unlocking portion 220, wherein the unlocking portion 220 is connected to the operating portion 210, and its main function is to insert the unlocking portion 220 into the unlocking hole 111 through the self-unlocking hole 111 to separate the blocking member 100. When the blocking member 100 needs to be unlocked, the operator first needs to align the unlocking portion 220 of the unlocking member 200 with the unlocking hole 111, and then insert the unlocking portion 220 into the unlocking hole 111. After the unlocking portion 220 is inserted, the operator can rotate the unlocking member 200 so that the unlocking portion 220 and the unlocking hole 111 are at least partially misaligned.

[0075] This design ensures that during operation, the unlocking portion 220 can firmly abut against the inner side of the blocking frame 110, thereby providing support for subsequent operations. The operator can easily drive the unlocking member 200 by holding the operating portion 210, thereby effectively pulling the blocking member 100 out of the plug-in frame 23. This structural design not only improves the convenience of operation, but also greatly reduces the risks caused by improper operation, thereby improving overall safety.

[0076] Furthermore, the specific implementation of the unlocking member 200 may include various types of materials and structures. The operating portion 210 may be designed to have a good grip, such as an ergonomically designed handle, which can improve the comfort and stability of the operation. The unlocking portion 220 may be equipped with a spring mechanism to ensure that the unlocking portion has a certain self-locking effect when inserted into the unlocking hole 111, thereby increasing the reliability of the operation. At the same time, the material of the unlocking portion 220 may be selected from a wear-resistant alloy material to enhance durability and ensure stable performance after long-term use. In one embodiment, the operating portion 210 may be a plate-like structure so that the operator can fix the operating portion 210 with his fingers, and then it is also convenient for the operator to rotate the unlocking member 200, which has a simple structure and is easy to operate.

[0077] In one embodiment, the design of the unlocking member 200 can be further optimized to improve the flexibility and stability of its operation. The unlocking member 200 can include an extension portion 230, which is respectively connected to the operating portion 210 and the unlocking portion 220. Such a structural design can effectively increase the distance between the operating portion 210 and the unlocking portion 220. When the operator needs to unlock the blocking member 100, the extension portion 230 allows them to operate in a larger range, making the unlocking process more convenient. This design is particularly suitable for environments with limited space or requiring precise operation, and effectively improves the comfort and efficiency of use.

[0078] In addition, the unlocking portion 220 can be further divided into a connecting section 221 and a limiting section 222, wherein the connecting section 221 is connected to the operating portion 210 and the limiting section 222, respectively. The limiting section 222 is protruded outward from the surface of the connecting section 221, and is intended to provide additional positioning and support for the operation process. When the unlocking portion 220 is inserted into the self-unlocking hole 111, the limiting section 222 can be firmly abutted against the inner side of the blocking frame 110, thereby providing additional support for the unlocking of the blocking member 100. This design ensures that when the blocking member 100 is driven to separate, the risk of misoperation can be effectively reduced, thereby improving the overall safety and reliability.

[0079] Through such a structural design, the unlocking member 200 shows strong adaptability in practical applications and can conveniently cope with various working conditions. The design of the extension portion 230 helps to optimize the visual and manual operation, while the combination of the connecting section 221 and the limiting section 222 improves the stability and accuracy of the operation, helps to extend the service life of the equipment and reduce the maintenance frequency.
