Abstract

This invention discloses a pluggable industrial gateway for network security in new energy power plants, relating to the field of industrial gateway technology, including a housing and an adaptive blind-mating assembly. This pluggable industrial gateway for network security in new energy power plants, on the one hand, utilizes a floating sub-base that achieves multi-directional adaptive adjustment through an elastic body, compensating for positional deviations and avoiding poor contact caused by installation errors or external impacts. On the other hand, the combination of a slider and a spring triggers sliding when the insertion force exceeds the limit, physically limiting and preventing hard collisions between the interface module and the main control board, thus compensating for connector damage problems caused by the lack of buffering mechanisms in traditional interfaces. This application, on the one hand, provides guidance for blind mating through a multi-level stepped flared mouth structure guide groove; on the other hand, it provides safety protection for the interface module by preventing misalignment and over-the-top insertion through redundant safety design, automatically correcting the plug position, and solving the problem of poor contact caused by installation tolerances in traditional interfaces.

Description

Technical Field

[0001] This invention relates to the field of industrial gateway technology, specifically a pluggable industrial gateway for network security in new energy power plants. Background Technology

[0002] Industrial communication gateways are crucial devices in the Industrial Internet of Things (IIoT) field. They connect different networks and enable data transmission, combining traditional industrial control equipment with modern network technology to achieve broader monitoring and management of industrial production processes. They can acquire, convert, and process data, and provide functions such as equipment management and security protection. An industrial communication gateway consists of both hardware and software components. The standard hardware supports both serial and Ethernet physical connection methods. Through a pluggable backplane, it can support various fieldbuses such as CC-Link, CANBus, DeviceNet, Profibus, and LonWorks, achieving unification and standardization of different physical connection methods.

[0003] The shortcomings of pluggable backplanes in traditional industrial communication gateways are as follows: the blind-insertion guidance structure of traditional gateway interfaces is poorly designed, making it difficult for users to quickly align the interface position during blind insertion. This is mainly due to the fact that traditional gateway interfaces are mostly rigid connections, which lack position compensation capabilities. The lack of anti-misalignment function leads to insufficient connection reliability. Not only can they not adaptively adjust for slight deviations during blind insertion, but the inability to intuitively judge the insertion depth also makes it easy to apply excessive insertion force, causing hard collisions between the interface module and the main control board. The lack of over-the-top protection can also lead to hardware damage. In specific designs, anti-misalignment requires a stable multi-directional floating guide structure, while over-the-top protection requires a sliding buffer avoidance structure. The two are prone to layout interference in the narrow space of the gateway interface. The above-mentioned structural compatibility conflict is the core design contradiction faced by designers when integrating anti-misalignment and over-the-top protection functions. Summary of the Invention

[0004] The purpose of this invention is to provide a pluggable industrial gateway for network security in new energy power plants to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pluggable industrial gateway for network security in new energy power plants, comprising a housing and an adaptive blind-plug assembly. The adaptive blind-plug assembly is installed at the end of the housing. The adaptive blind-plug assembly includes an interface plate bolted to the end of the housing. A guide groove is provided on the interface plate, and a bracket is fixedly installed at the bottom of the inner side of the guide groove. A guide rod is fixedly connected to the inner side of the bracket recess, and a slider is slidably installed on the guide rod. A spring is sleeved on the guide rod, and the slider is elastically connected to the side wall of the bracket recess through the spring. A female seat is detachably connected to the slider, and a circular floating cavity is provided inside the female seat, and an elastic body with an annular structure is embedded inside the floating cavity.

[0006] Furthermore, the guide groove on the interface board has a multi-level stepped horn-shaped structure, and the axis of the guide groove coincides with the center of the elastic body annular structure.

[0007] Furthermore, a module replacement component is detachably connected between the female seat and the slider. The module replacement component includes a plug plate fixedly connected to the bottom end of the female seat. A lifting groove is horizontally opened at the upper end of the plug plate, and an I-shaped push plate slides vertically inside the lifting groove. The long flange at the top of the I-shaped push plate is located on both sides of the bottom end of the female seat.

[0008] Furthermore, the module replacement component also includes recessed slots on both sides of the lower end of the plug-in plate. "L"-shaped card blocks are installed on the outer side of the slots, and the card blocks on both sides are mirror-symmetrical on both sides of the plug-in plate. The card blocks are respectively installed on both sides of the recess at the top of the slider, and the inner end face of the card block abuts against the shorter flange at the bottom of the I-shaped push plate.

[0009] Furthermore, the module replacement component also includes torsion spring rods corresponding to the rotation axes of the two side blocks. The rod portion of the torsion spring rod is fixedly connected to the inner walls of the two sides of the top notch of the slider, and the blocks are elastically connected to the inner walls of the top notch of the slider through the torsion spring portion of the torsion spring rod.

[0010] Furthermore, the female seat is equipped with a convenient exit component, which includes an interface module installed on the end of the female seat away from the guide groove. The end of the interface module is integrally fixed with a male seat, which is a disc structure that cooperates with the annular cavity of the elastic body. The male seat can float up, down, left, and right in the floating cavity by squeezing the elastic body and deforming it.

[0011] Furthermore, the convenient exit component also includes an insertion cavity axially disposed inside the interface module, a plug is axially inserted into the insertion cavity, and a locking hole is provided at the bottom of the plug end face, and when the plug is deeply inserted into the insertion cavity, it establishes an electrical connection with the corresponding contact point on the inner wall of the interface module.

[0012] Furthermore, the convenient withdrawal component also includes a Z-shaped locking block rotatably mounted at the bottom of the insertion cavity. One side of the Z-shaped locking block has a locking pin that engages with a locking slot provided at the bottom of the plug end face, and the other end of the Z-shaped locking block is elastically connected to the inner wall of the insertion cavity through a support spring.

[0013] Furthermore, the convenient exit component also includes a clearance opening at the bottom of the interface module end face. A trigger rod is provided inside the clearance opening, and one side of the trigger rod abuts against the Z-shaped locking block when the end of the Z-shaped locking block reaches a preset position. The other side of the trigger rod is fixedly connected to the top end of the bracket.

[0014] Furthermore, a main control board is installed inside the housing, and the interface on the main control board is electrically connected to the adapter in the middle of the end face of the corresponding functional interface module through a flexible connector.

[0015] This invention provides a pluggable industrial gateway for network security in new energy power plants, which has the following advantages;

[0016] 1. In use, this application achieves multi-directional adaptive adjustment through an elastic body, compensating for positional deviations and avoiding poor contact caused by installation errors or external impacts, significantly outperforming the fragility of traditional rigid connections. On the other hand, the female connector is detachably connected to the slider, preventing over-application. The combination of the slider and spring triggers sliding when the insertion force exceeds the limit, preventing hard collisions between the interface module and the main control board through physical limits, thus compensating for connector damage caused by the lack of buffering mechanisms in traditional interfaces. This application provides guidance for blind insertion through a multi-stage stepped flared mouth structure guide groove, and provides safety protection for the interface module by preventing insertion misalignment and over-application through redundant safety design, automatically correcting the plug position and solving the problem of poor contact caused by installation tolerances in traditional interfaces.

[0017] 2. This application achieves one-handed operation of "push-in unlocking" by triggering the trigger rod to unlock by pushing the plug inward, which solves the pain point of traditional interfaces that require tools or complicated steps to unlock, and is especially suitable for industrial environments with narrow spaces.

[0018] 3. This application enables the rapid replacement of interface modules with different functions. Through modular design, it allows users to quickly replace interface modules with different functions without stopping the system. It supports plug-and-play functionality for multiple types of interface modules, solving the problems of single interface and poor scalability of traditional gateways. Attached Figure Description

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figures 1 to 4 This invention provides a technical solution: a pluggable industrial gateway for network security in new energy power plants, comprising a housing 1 and an adaptive blind-plug assembly 4. The adaptive blind-plug assembly 4 is installed at the end of the housing 1. The adaptive blind-plug assembly 4 includes an interface plate 401 bolted to the end of the housing 1. A guide groove 402 is provided on the interface plate 401, and a bracket 403 is fixedly installed at the bottom of the inner side of the guide groove 402. A guide rod 404 is fixedly connected to the inner side of the recess of the bracket 403, and a sliding mount is installed on the guide rod 404. There is a slider 405, and a spring 406 is sleeved on the guide rod 404. The slider 405 is elastically connected to the side wall of the recess of the bracket 403 through the spring 406. A female seat 407 is detachably connected to the slider 405. The female seat 407 has a circular floating cavity 408 inside, and an elastic body 409 with an annular structure is embedded inside the floating cavity 408. The guide groove 402 provided on the interface plate 401 has a multi-level stepped flared structure, and the axis of the guide groove 402 coincides with the center of the annular structure of the elastic body 409.

[0030] The specific operation is as follows: When blindly inserting the plug 604, the user first achieves coarse positioning through the guide groove 402 of the multi-stage stepped flared structure on the interface board 401. Geometric guidance reduces the difficulty of blind insertion, accurately guiding the plug 604 to the interface module 601 on the back of the guide groove 402. During use, the integrated fixed disc-shaped sub-base 602 at the end of the interface module 601 floats within the cavity of the female base 407. The sub-base 602, by compressing the elastic body 409 and deforming it, floats up, down, left, and right within the floating cavity 408. This allows the interface module 601 to self-adjust its position through multi-directional floating, preventing misalignment. The floating sub-base 602, through the elastic body 409, achieves multi-directional self-adjustment, compensating for positional deviations and avoiding poor contact caused by installation errors or external impacts. This is significantly superior to the fragility of traditional rigid connections. On the one hand, the female connector 407 is detachably connected to the slider 405. In order to prevent the user from violently damaging the interface, when the insertion force applied by the user is greater than the force that compresses the spring 406, the slider 405 can drive the female connector 407 to slide on the guide rod 404 inside the bracket 403, thereby preventing over-extension. The combination of slider 405 and spring 406 triggers sliding when the insertion force exceeds the limit. Through physical limitation, it prevents the interface module 601 from hard collision with the main control board 2, which makes up for the connector damage problem caused by the lack of buffer mechanism in traditional interfaces. On the one hand, this application provides guidance for blind insertion by using the multi-stage stepped flared mouth structure guide groove 402. On the other hand, it prevents insertion deviation and over-extension through redundant safety design, provides safety protection for the interface module 601, automatically corrects the position of plug 604, and solves the contact problem caused by installation tolerance in traditional interfaces.

[0031] Please see Figure 5 A module replacement assembly 5 is detachably connected between the female base 407 and the slider 405. The module replacement assembly 5 includes a plug-in plate 501 fixedly connected to the bottom end of the female base 407. A lifting groove 502 is horizontally opened through the upper end of the plug-in plate 501, and an I-shaped push plate 503 slides vertically inside the lifting groove 502. The long flange at the top of the I-shaped push plate 503 is located on both sides of the bottom end of the female base 407. The module replacement assembly 5 also includes a slot 504 recessed on both sides of the lower end of the plug-in plate 501. An "L"-shaped locking block 505 is installed on the outer side of the slot 504. The two side blocks 505 are located on both sides of the plug plate 501 in a mirror symmetrical manner, and the blocks 505 are respectively installed on both sides of the top recess of the slider 405. The inner end face of the block 505 abuts against the shorter flange at the bottom of the I-shaped push plate 503. The module replacement component 5 also includes a torsion spring rod 506 corresponding to the rotation axis of the two side blocks 505. The rod part of the torsion spring rod 506 is fixedly connected to the inner wall of both sides of the top recess of the slider 405, and the block 505 is elastically connected to the inner wall of both sides of the top recess of the slider 405 through the torsion spring part of the torsion spring rod 506.

[0032] The specific operation is as follows: When installing the interface module 601 with the required function or replacing the damaged interface module 601, simply loosen the screws to remove the interface board 401 from the end of the housing 1, disconnect the elastic connector 3 connecting the interface module 601 to the main control board 2, and push down the I-shaped push plate 503 at the upper end of the bottom plug-in plate 501 of the female connector 407. This will cause the bottom flange of the I-shaped push plate 503 to abut against the "L"-shaped locking blocks 505 on both sides of the top notch of the slider 405. This will overcome the torsion spring force, causing the "L"-shaped locking blocks 505 on both sides to open and release the locked plug-in plate 501, ultimately allowing the interface module to be installed. 601 and its corresponding female connector 407 are removed from the slider 405. Then, a new interface module 601 is replaced and inserted directly into the notch at the top of the slider 405. When the plug plate 501 of the new interface module 601 is inserted into the gap between the "L"-shaped clips 505 on both sides, it is self-locked and fixed. Then, the elastic connector 3 is reconnected to realize the quick replacement of interface modules 601 with different functions. The modular design allows users to quickly replace interface modules 601 with different functions without stopping the system. It supports plug-and-play of multiple types of interface modules 601 and solves the problems of single interface and poor scalability of traditional gateways.

[0033] Please see Figures 6 to 8 The female connector 407 is equipped with a convenient ejection component 6. The convenient ejection component 6 includes an interface module 601 installed at the end of the female connector 407 opposite to the guide groove 402. A male connector 602 is integrally fixed to the end of the interface module 601. The male connector 602 is a disc structure that mates with the annular cavity of the elastic body 409. The male connector 602 can float up, down, left, and right within the floating cavity 408 by compressing and deforming the elastic body 409. The convenient ejection component 6 also includes an insertion cavity 603 axially located inside the interface module 601. A plug 604 is axially inserted into the insertion cavity 603. The bottom of the end face of the plug 604 has a locking slot 605. When the plug 604 is inserted into the insertion cavity 603, it establishes an electrical connection with the corresponding contact point on the inner wall of the interface module 601. The convenient ejection component 6 also includes... The Z-shaped locking block 606 is rotatably installed at the bottom of the insertion cavity 603. One side of the locking pin of the Z-shaped locking block 606 engages with the locking port 605 at the bottom of the end face of the plug 604. The other end of the Z-shaped locking block 606 is elastically connected to the inner wall of the insertion cavity 603 through the support spring 607. The convenient withdrawal component 6 also includes a clearance port 608 at the bottom of the end face of the interface module 601. A trigger rod 609 is provided inside the clearance port 608. One side of the trigger rod 609 abuts against the Z-shaped locking block 606 when the end of the Z-shaped locking block 606 reaches the preset position. The other side of the trigger rod 609 is fixedly connected to the top end of the bracket 403. The main control board 2 is installed inside the housing 1. The interface on the main control board 2 is electrically connected to the adapter in the middle of the end face of the interface module 601 with the corresponding function through the elastic connector 3.

[0034] The specific operation is as follows: When the plug 604 is inserted into the insertion cavity 603 of the interface module 601, the end of the plug 604 presses the locking pin on one side of the Z-shaped locking block 606, causing the end of the Z-shaped locking block 606 on the other side to rotate against the elastic force of the support spring 607. After the plug 604 passes through, it resets and locks itself in the locking slot 605 at the bottom of the end face of the plug 604, realizing automatic locking after the plug 604 is connected. This prevents the plug 604 from loosening and falling out of the interface module 601. It provides vibration- and impact-resistant mechanical locking without manual operation. Compared with the traditional snap-on design, it avoids the risk of loosening due to long-term vibration. At this time, the plug 604 is connected to the adapter at the end of the interface module 601, and the adapter enters... An electrical connection is established by connecting the flexible connector 3 to the main control board 2 on the housing 1. When the plug 604 is removed, the user only needs to push the plug 604 inward with a little force, so that the female socket 407 drives the interface module 601 to slide with the slider 405. This allows the trigger rod 609 on the top of the end face of the bracket 403 to extend through the clearance port 608 and contact the end part of the Z-shaped locking block 606 on the other side. Finally, under the action of external force, the Z-shaped locking block 606 releases the locked plug 604. That is, the user triggers the trigger rod 609 to unlock by pushing the plug 604 inward, realizing the one-handed operation of "push-in unlock". This solves the pain point of traditional interfaces that require tools or complicated steps to unlock, and is especially suitable for industrial environments with narrow spaces.

[0035] In summary, when using this pluggable industrial gateway for network security in new energy power plants:

[0036] First, when blindly inserting the plug 604, the user first achieves coarse positioning through the guide groove 402 of the multi-stage stepped flared structure on the interface board 401. Geometric guidance reduces the difficulty of blind insertion, accurately guiding the plug 604 to the interface module 601 on the back of the guide groove 402. During use, on one hand, the integrated, fixed disc-shaped sub-base 602 at the end of the interface module 601 floats within the cavity of the female base 407. The sub-base 602, by compressing the elastic body 409 and deforming it, floats up, down, left, and right within the floating cavity 408. This allows the interface module 601 to self-adjust its position through multi-directional floating, preventing misalignment. The floating sub-base 602, through the elastic body 409, achieves multi-directional self-adjustment, compensating for positional deviations and avoiding poor contact caused by installation errors or external impacts. This is significantly superior to the fragility of traditional rigid connections. On the other hand… The female connector 407 is detachably connected to the slider 405. To prevent users from violently damaging the interface, when the insertion force applied by the user is greater than the force that compresses the spring 406, the slider 405 can drive the female connector 407 to slide on the guide rod 404 inside the bracket 403, thereby preventing over-extension. The combination of slider 405 and spring 406 triggers sliding when the insertion force exceeds the limit, and prevents the interface module 601 from hard collision with the main control board 2 through physical limiting, thus making up for the connector damage problem caused by the lack of buffer mechanism in traditional interfaces. On the one hand, this application provides guidance for blind insertion by using the multi-stage stepped flared mouth structure guide groove 402, and on the other hand, it provides safety protection for the interface module 601 by using redundant safety design to prevent insertion deviation and over-extension, automatically corrects the position of the plug 604, and solves the contact problem caused by installation tolerance in traditional interfaces.

[0037] Secondly, when the plug 604 is inserted into the insertion cavity 603 of the interface module 601, the end of the plug 604 presses the locking pin on one side of the Z-shaped locking block 606, causing the end of the Z-shaped locking block 606 on the other side to rotate against the elastic force of the support spring 607. After the plug 604 passes through, it resets and locks itself in the locking slot 605 at the bottom of the end face of the plug 604, achieving automatic locking after the plug 604 is connected. This prevents the plug 604 from loosening and falling out of the interface module 601, providing vibration- and shock-resistant mechanical locking without manual operation. Compared with the traditional snap-on design, this avoids the risk of loosening due to long-term vibration. At this time, the plug 604 is connected to the adapter at the end of the interface module 601, and the adapter then... An electrical connection is established by connecting the flexible connector 3 to the main control board 2 on the housing 1. When the plug 604 is removed, the user only needs to push the plug 604 inward with a little force, so that the female socket 407 drives the interface module 601 to slide with the slider 405. This allows the trigger rod 609 on the top of the end face of the bracket 403 to extend through the clearance port 608 and contact the end part on the other side of the Z-shaped locking block 606. Finally, under the action of external force, the Z-shaped locking block 606 releases the locked plug 604. That is, the user triggers the trigger rod 609 to unlock by pushing the plug 604 inward, realizing the one-handed operation of "push-in unlock". This solves the pain point of traditional interfaces requiring tools or complicated steps to unlock, and is especially suitable for industrial environments with narrow spaces.

[0038] Finally, when installing the interface module 601 with the required functions or replacing the damaged interface module 601, simply loosen the screws to remove the interface board 401 from the end of the housing 1, disconnect the elastic connector 3 connecting the interface module 601 to the main control board 2, and push down the I-shaped push plate 503 at the top of the bottom plug-in plate 501 of the female connector 407. This will cause the bottom flange of the I-shaped push plate 503 to abut against the "L"-shaped locking blocks 505 on both sides of the top notch of the slider 405. This will overcome the torsion spring force, causing the "L"-shaped locking blocks 505 on both sides to open and release the locked plug-in plate 501, thus finally allowing the interface module 601 to be installed. 1 and the corresponding female connector 407 are removed from the slider 405. Then, a new interface module 601 is replaced and inserted directly into the notch at the top of the slider 405. When the plug plate 501 of the new interface module 601 is inserted into the gap between the "L"-shaped clips 505 on both sides, it is self-locked and fixed. Then, the elastic connector 3 is reconnected to realize the quick replacement of interface modules 601 with different functions. The modular design allows users to quickly replace interface modules 601 with different functions without stopping the system. It supports plug-and-play of multiple types of interface modules 601, solving the problems of single interface and poor scalability of traditional gateways.

[0039] Specifically, the implementation and beneficial effects of the adaptive blind-insertion component 4:

[0040] Component composition and assembly: Refer to Figures 1 to 4The interface plate 401 is fixed to the end of the housing 1 by M4 hexagonal bolts. The guide groove 402 is CNC precision machined and has a multi-stage stepped flared opening structure. The maximum port diameter is 25mm, and the minimum port diameter matches the outer diameter (12mm) of the interface module 601, with a tolerance of H7 / g6. The bracket 403 is fixed to the bottom inner side of the guide groove 402 by laser welding. The guide rod 404 is a 5mm diameter optical shaft, and its two ends are fixed to the inner side of the recess of the bracket 403 by interference fit. The slider 405 has a linear bearing embedded inside, which allows it to slide smoothly on the guide rod 404. The spring 406 is a stainless steel helical compression spring with an elastic coefficient k=1.5 N / mm and a pre-compression amount of 5mm.

[0041] Implementation of anti-misalignment function: such as Figure 7 As shown, the elastomer 409 is a silicone ring with a Shore A hardness of 60, which is interference-fitted into the floating cavity 408 of the female connector 407. When the interface module 601 is subjected to a lateral offset force, the force is transmitted to the elastomer 409 through the male connector 602, causing it to undergo elastic deformation. Due to the isotropic nature of the elastomer 409, the male connector 602 is allowed to float radially by ±1.5mm and deflect by ±2° within the floating cavity 408. This structure can automatically compensate for deviations caused by machining tolerances or misalignment during blind insertion, ensuring that the pins of the plug 604 can be smoothly aligned with the insertion cavity 603. This achieves the "position self-adaptation" function that traditional rigid connections cannot achieve, fundamentally solving the problems of poor contact and connector damage caused by "insertion misalignment".

[0042] The over-the-top protection function is implemented as follows: When the insertion force is too large (exceeding the preset elastic force of spring 406, for example, greater than 20N), the slider 405 will compress the spring 406 and slide backward along the guide rod 404. The maximum sliding stroke is 8mm. This sliding stroke forms a mechanical buffer zone, which effectively absorbs excessive impact energy. When the slider 405 slides to contact the inner wall of the bracket 403, the movement stops, forming a hard limit. This mechanism physically prevents the interface module 601 from having a hard collision with the main control board 2 behind it, solving the risk of hardware damage caused by the lack of buffer in traditional designs.

[0043] Implementation and beneficial effects of module replacement component 5:

[0044] Component composition and quick locking / releasing mechanism: Refer to Figure 5When replacing the interface module 601, the operator presses down on the I-shaped push plate 503, and the shorter flange at the bottom of the I-shaped push plate 503 descends accordingly. At the same time, it presses the inner end faces of the two "L"-shaped locking blocks 505 to both sides. The locking blocks 505 rotate around the torsion spring rod 506, overcoming the torque of the torsion spring (about 0.1 N·m) and opening up, thereby releasing the locking force on the locking slot 504 on the plug plate 501. At this time, the entire female seat 407 and the interface module 601 can be vertically pulled out from the slider 405.

[0045] This design frees the gateway from being limited to fixed interfaces. Users can prepare various functional interface modules 601 according to on-site needs. The replacement process does not require complex tools or disassembling the entire gateway shell and can be completed in just 1-2 minutes, realizing true "hot-swappable" functional expansion. Compared with the cumbersome process of traditional gateways requiring complete replacement or disassembly and soldering by professionals, this greatly improves the flexibility and operation and maintenance efficiency of the equipment and solves the pain point of diverse interface types and frequent upgrades in new energy power plants.

[0046] The implementation and beneficial effects of the convenient exit component 6:

[0047] Automatic locking and secure exit mechanisms: See [link / reference] Figure 6 and Figure 8 When the plug 604 is inserted, its beveled end presses against the locking pin of the Z-shaped locking block 606, causing the locking block to rotate around the axis and compress the support spring 607. When the plug 604 is inserted into place and the locking port 605 is aligned with the locking pin, the elastic force (about 1N) of the support spring 607 pushes the Z-shaped locking block 606 to reset, and the locking pin is engaged in the locking port 605, completing the automatic locking. This locking method is more reliable than the traditional friction connection and can effectively resist vibration.

[0048] The innovation of "push-in unlock": When it is necessary to unplug the plug 604, the operator does not pull it out directly, but applies a short, slightly larger push (about 15N) to the plug 604 in the insertion direction. This push causes the entire interface module 601 and the female socket 407 assembly to move slightly backward (about 2mm) against the force of the spring 406. This small displacement allows the trigger rod 609, which is fixed to the top of the bracket 403, to enter the insertion cavity 603 through the clearance port 608 and press against the end of the Z-shaped locking block 606, forcing it to rotate and unlock. Then, the operator can easily unplug the plug 604.

[0049] This "push-in unlock" one-handed operation mode cleverly links the originally independent functions of the "overshoot" buffer stroke (sliding slider 405) and the "unlock" action (triggered by trigger rod 609), forming a novel and efficient linkage mechanism. It solves the industry problem of unlocking small connectors in narrow spaces. This functional integration method is not a conventional design idea for those skilled in the art and reflects outstanding substantive features.

[0050] This invention is not a simple superposition of components, but rather, through ingenious mechanical design, the adaptive blind insertion component 4 (anti-misalignment / anti-over-top), the module replacement component 5 (quick replacement), and the convenient exit component 6 (push-in to unlock) form an organic whole, producing a beneficial effect of synergistic efficiency.

[0051] The anti-misalignment function ensures the interface docking accuracy after module replacement; the buffer travel of the anti-overshoot function is conveniently reused by the exiting component as the unlocking trigger condition; the modular design provides the application carrier and platform for maximizing the value of the former two.

[0052] This invention ultimately provides an industrial gateway interface solution that integrates "high-precision blind insertion alignment, overload impact protection, modular and flexible expansion, and one-handed quick locking and unlocking". The overall realization of these effects surpasses the conventional technical means (such as simply strengthening the structural rigidity or adding more complex guiding mechanisms) that those skilled in the art can expect when solving the contradiction between "anti-insertion deviation" and "anti-overhead" problems, and brings about significant technological progress.
