Description

Technical Field

[0001] This invention relates to the field of fiber optic patch cord pigtail insertion and removal technology, specifically to a fiber optic patch cord pigtail with an easy-to-insert and easy-to-remove guiding structure. Background Technology

[0002] Fiber optic communication has become the core transmission method of modern communication networks. As a key component in optical paths to achieve detachable connections, the performance of fiber optic connectors directly affects the stability and reliability of the entire communication system. Among the many types of fiber optic connectors, SC type connectors are widely used in fiber optic distribution frames, network equipment interconnection, and fiber-to-the-home scenarios due to their advantages such as low price, convenient insertion and removal operation, small insertion loss fluctuation, high compressive strength, and high installation density. SC type fiber optic connectors adopt a plug-in latch fastening method, have a rectangular shell, and rely on a push-pull self-locking structure to achieve quick connection and separation with the adapter without rotation operation. This makes them significantly convenient to operate in high-density cabling environments.

[0003] However, this direct-plug and spring-locking design mechanism has revealed several inherent defects in practical applications, affecting its applicability in critical links and high-reliability scenarios. SC connectors use plastic clips for locking, which have weaker locking force compared to the threaded locking method of FC interfaces. Under equipment vibration, accidental cable pulling, or high-density cabling environments, the connectors are prone to accidental loosening or even falling out, resulting in optical signal interruption. In some SC field-assembled connectors, the internal clamping mechanism needs to achieve the engagement and fixation of the optical fiber through relative movement. During this process, the optical fiber between the clamping part and the ferrule is prone to excessive bending or even twisting. Frequent plugging and unplugging operations will cause the clamping force of the pressure plate to decrease, thereby increasing insertion loss or even causing optical fiber breakage. In addition, in high-density cabling scenarios, when multiple SC connectors are closely arranged, it is difficult for operators to insert their fingers into the gaps between adjacent connectors to pinch the sheath for pulling out, making plugging and unplugging extremely inconvenient.

[0004] Existing SC-type fiber optic patch cord pigtails suffer from several technical problems during insertion and removal, including insufficient locking reliability, lack of guiding connection, easy damage to internal optical fibers, and operational difficulties in high-density scenarios. To address these issues, we propose an easy-to-insert and guide structure fiber optic patch cord pigtail. Summary of the Invention

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] An easily pluggable and unpluggable fiber optic patch cord pigtail with a guiding structure is provided, which has the following advantages:

[0019] This invention solves the technical problem of existing SC fiber optic connectors lacking a guide protrusion at the insertion end and correspondingly opening a guide hole on the top surface of the connector. The precise sliding fit between the guide protrusion and the guide hole ensures that the SC connector can only move linearly along its axis during insertion. This effectively addresses the issue of damage to the internal fiber optic cable caused by the lack of a guide during insertion in existing SC fiber optic connectors, and avoids fiber end-face collision damage or ferrule bending caused by insertion angle deviation. Simultaneously, by setting rectangularly spaced, equidistant locking guide ramps at the insertion end of the SC connector, and sliding locking slides driven by micro-springs within the locking adjustment grooves on both sides of the fiber optic connector platform, the SC connector, after insertion, can release the spring force through the micro-springs, pushing the two locking slides outward to form a double locking mechanism with the insertion elastic locking platform inside the connector, significantly enhancing the insertion efficiency. The locking force and pull-out resistance effectively prevent optical signal interruption caused by connector loosening under equipment vibration or cable pulling conditions. In addition, by setting a reset drive mechanism on the top surface of the SC connector, consisting of a reset drive slide, a reset spring, a steering shaft, a steering threaded groove, and a steering drive boss, and cooperating with a reset steering mechanism consisting of a drive gear, a transmission gear, and a drive adapter slide, the operator only needs to press the reset drive slide with one finger to convert linear motion into rotational motion through helical transmission. Then, through the meshing of the gear and rack, the two locking slides retract in opposite directions to simultaneously release all locking points. After pulling out, releasing the press will cause the reset spring to drive all components to automatically reset to the ready-to-plug state. This realizes easy one-handed plugging and unplugging operation in high-density wiring scenarios, effectively solving the technical problems of insufficient operating space and the weakening of locking force after frequent plugging and unplugging of existing SC connectors in high-density layout.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 The present invention provides a technical solution:

[0032] A pluggable fiber optic patch cord pigtail with a guide structure includes: a fiber optic patch cord pigtail SC connector 1, a fiber optic connection protective sleeve 2, an optical fiber optic cable 3, a device connector 4, and a fiber optic connector platform 13. The fiber optic connection protective sleeve 2 is fixedly connected to the side of the fiber optic patch cord pigtail SC connector 1, and the optical fiber optic cable 3 is fixedly connected to the inner side of the fiber optic connection protective sleeve 2. The device connector 4 is plugged into the outer end of the fiber optic patch cord pigtail SC connector 1, and the fiber optic connector platform 13 is fixedly connected to the inner side of the fiber optic patch cord pigtail SC connector 1. The fiber optic connector platform 13 connects to the optical fiber... The fiber optic connector 13 is fixedly connected to the fiber optic cable 13. The guide snap-fit ​​assembly includes a snap-fit ​​slide plate 12, a snap-fit ​​guide ramp 15, a snap-fit ​​miniature spring 16, a snap-fit ​​slide plate 2 17, a reset drive mechanism, and a reset steering mechanism. Snap-fit ​​miniature springs 16 are linearly and equidistantly distributed on the side of the fiber optic connector 13. Snap-fit ​​slide plate 12 and snap-fit ​​slide plate 2 17 are fixedly connected to the outer side of the snap-fit ​​miniature springs 16. Snap-fit ​​guide ramps 15 are rectangularly and equidistantly distributed at the insertion end of the fiber optic patch cord pigtail SC connector 1. The inner side is equipped with a reset and turning mechanism, and the top surface of the fiber optic patch cord pigtail SC connector 1 is equipped with a reset drive mechanism. The fiber optic patch cord pigtail SC connector 1 is made of flame-retardant PC engineering plastic injection molding, and its dimensions conform to the SC type connector standard specification, making it universally compatible with standard equipment ports. The fiber optic connection protective sleeve 2 is made of low-smoke halogen-free flame-retardant rubber and is fitted at the connection between the fiber optic cable 3 and the connector. It can buffer the bending stress of the cable, avoid the fiber optic root from breaking and losing due to repeated bending, and at the same time increase the grip friction to facilitate insertion and removal operations. The connector 13 is a precision bearing substrate inside the connector. It uses ceramic inserts to accurately position the fiber optic core and ensure the coaxiality of the optical axis during the connection. The guide snap-fit ​​assembly adopts a double-sided symmetrical snap-fit ​​structure. Snap-fit ​​slide plate 12 and snap-fit ​​slide plate 2 17 are pushed outward and locked under the drive of snap-fit ​​micro spring 16. With the guide of snap-fit ​​guide ramp 15, automatic snap-fit ​​is achieved upon insertion. The reset drive mechanism is linked with the reset steering mechanism. A single finger press can simultaneously unlock the double-sided snap-fit, which is suitable for one-handed operation in high-density cabling scenarios, eliminating the need to reach into gaps to pick out the connector.

[0033] Furthermore, the top surface of the device connector 4 is provided with a connector guide hole 5, and the top surface of the fiber optic patch cord pigtail SC connector 1 is fixedly connected with a guide boss 6. The guide boss 6 slides inside the connector guide hole 5. The connector guide hole 5 is opened at the top surface entrance of the device connector 4, which can guide the guide boss 6 to slide in smoothly, reducing the difficulty of insertion and alignment. Even if the line of sight is limited, it can be quickly blindly inserted and aligned. The guide boss 6 is integrally raised on the top surface of the fiber optic patch cord pigtail SC connector 1 and extends along the insertion direction. It forms a precise clearance fit with the connector guide hole 5, which can strictly limit the insertion freedom of the connector, so that it can only advance in a straight line along the axial direction, completely eliminating radial wobble and angular tilt during the insertion process. The guide structure can ensure that the internal insertion fiber head 9 is aligned with the fiber coupling sleeve of the device port with zero deviation, effectively avoiding problems such as fiber end face collision and chipping, ferrule bending and deformation, or excessive splicing loss caused by insertion angle deviation. It protects the fiber core from the insertion source, and at the same time provides a precise position reference for subsequent snap-fit ​​locking, ensuring accurate snap-fit ​​positioning.

[0034] Furthermore, a fiber optic connector 9 is fixedly connected to the side of the fiber optic connector 13. The fiber optic connector 9 is electrically connected to the inner side of the device connector 4. A symmetrically distributed flexible connector slot 28 is fixedly connected to the inner side of the device connector 4. A fiber optic patch cord pigtail SC connector 1 is connected to the outer side of the flexible connector slot 28. The end face of the fiber optic connector 9 is ultra-precision ground and polished, and the surface roughness and end face curvature strictly meet the communication standards. After being inserted into the device connector 4, it can achieve low-loss, high-return-loss optical connection. The symmetrically arranged insertion elastic locking platforms 28 on the inner side of the first 4 are made of high-elasticity engineering plastic, which has excellent fatigue resistance. The locking protrusion faces the inlet side and is set with an inlet slope. The back side is a vertical stop surface. After the connector is inserted into place, the locking slide plate 12 and the locking slide plate 27 pop outward and form a rigid locking with the back stop surface of the insertion elastic locking platform 28. Combined with the clamping force of the connector body and the locking platform, a double locking structure is formed, which greatly improves the tensile strength and vibration resistance of the connector. It is not easy to loosen or break when the equipment vibrates or the cable is pulled.

[0035] Furthermore, the fiber optic connector 13 has symmetrically distributed snap-fit ​​adjustment grooves 10 on its side. A snap-fit ​​miniature spring 16 is fixedly installed inside the snap-fit ​​adjustment groove 10. Snap-fit ​​sliding plates 12 and 17 are slidably connected to the inner sides of the snap-fit ​​adjustment grooves 10 on both sides of the fiber optic connector 13, respectively. The sides of snap-fit ​​sliding plates 12 and 17 are fixedly connected to the snap-fit ​​miniature spring 16. The top surface of the fiber optic connector 13 has symmetrically distributed adjustment communication holes 11, which connect to the inner side of the snap-fit ​​adjustment grooves 10. The tops of snap-fit ​​sliding plates 12 and 17 slide inside the adjustment communication holes 11. The snap-fit ​​adjustment grooves 10 are symmetrically distributed on both sides of the fiber optic connector 13. The groove wall is treated with wear-resistant hardening and precisely fits into the side protrusions of the snap-fit ​​sliding plate 12 and snap-fit ​​sliding plate 2 17. This strictly limits the movement direction of the sliding plate, ensuring that it only slides horizontally in the radial direction and does not tilt or twist. Multiple sets of snap-fit ​​micro springs 16 are arranged linearly and equidistantly in the groove, applying force evenly at multiple points. This can stably push the sliding plate outward, ensuring that the snap-fit ​​force is evenly distributed along the length of the sliding plate and that the snap-fit ​​is tight and gapless. The adjustment and connecting hole 11 extends vertically through the top of the groove, connecting the snap-fit ​​cavity with the top reset adjustment cavity. The transmission boss on the top of the sliding plate passes through the hole and connects to the upper drive transfer sliding plate, realizing the transmission conversion from the top pressing force to the bottom snap-fit ​​force. There is no need to set up operating parts on the side, further reducing the overall size of the joint.

[0036] Furthermore, a reset adjustment platform 7 is fixedly connected to the top surface of the fiber optic patch cord pigtail SC connector 1. The top surface of the reset adjustment platform 7 has a reset installation stepped hole 18. A reset drive mechanism is provided inside the reset installation stepped hole 18. The reset adjustment platform 7 protrudes from the center of the top surface of the fiber optic patch cord pigtail SC connector 1. The platform surface is slightly higher than the surface of the connector body, which facilitates precise pressing with fingers and prevents accidental contact with other parts. The reset installation stepped hole 18 is a two-stage variable diameter vertical hole, which is opened in the center of the reset adjustment platform. The larger diameter section at the top accommodates the reset drive slide 8 and the reset spring 21, while the smaller diameter section at the bottom accommodates the steering shaft 23. The stepped structure can limit the downward stroke of the reset drive slide and the installation position of the steering shaft respectively. The stepped cavity arranges the operating parts and transmission parts in layers, and the operating surface is concentrated on the top surface of the connector. The operator only needs to press on the top of the connector to complete the unlocking, without having to put fingers into the gaps between the connectors. It is perfectly adapted to the use scenarios of high-density patch panels and densely arranged equipment ports, which greatly improves the convenience of plugging and unplugging operations.

[0037] Furthermore, the reset drive mechanism includes a reset drive slide 8, a reset spring 21, and a steering shaft 23. The reset spring 21 is fixedly connected to the inner side of the reset mounting stepped hole 18, and the reset drive slide 8 is fixedly connected to the top surface of the reset spring 21. The reset drive slide 8 slides within the reset mounting stepped hole 18. The steering shaft 23 is rotatably mounted within the reset mounting stepped hole 18. An adjustment transmission assembly is provided between the reset drive slide 8 and the steering shaft 23. The top surface of the reset drive slide 8 has an anti-slip frosted finish, providing a clear tactile feel. The top surface is exposed on the reset adjustment table surface, facilitating finger pressure. The return spring 21 is sleeved on the outside of the steering shaft 23, with its bottom supported on the stepped surface of the stepped hole and its top abutting against the bottom of the return drive slide. Normally, it is in the extended state, which lifts the return drive slide upward to the initial high position. The steering shaft 23 is vertically rotated and installed in the center of the stepped hole. As the core component for motion mode conversion, it can convert the vertical linear motion of the return drive slide into its own rotational motion, and then output it to the drive gear at the bottom. The spring-driven return design allows all components to automatically spring back and reset after being pressed and released, without the need for manual repositioning. Once released, it returns to the ready-to-plug state, making the operation smooth and efficient.

[0038] Furthermore, the adjusting rotation assembly includes a steering threaded groove 22 and a steering drive boss 29. The inner side of the reset drive slide 8 is fixedly connected with symmetrically distributed steering drive bosses 29. The outer side of the steering shaft 23 has symmetrically distributed steering threaded grooves 22. The steering drive bosses 29 slide within the steering threaded grooves 22. The steering threaded grooves 22 are symmetrically opened on the upper shaft of the steering shaft 23 and are continuous spiral grooves with smooth, wear-resistant walls. The steering drive bosses 29 are symmetrically fixed to the inner wall of the reset drive slide 8, with the protrusions embedded in the threaded grooves. Inside the spiral groove, when the reset drive slide is pressed down and moves linearly, the boss slides along the inclined surface of the spiral groove, decomposing the vertical thrust into a tangential torque, driving the steering shaft to rotate smoothly. The symmetrical double spiral groove design ensures balanced force distribution, with no off-center load or jamming during rotation, resulting in smooth and stable transmission. The thread helix angle has been optimized for high transmission efficiency and low pressing resistance, allowing for easy pressing with a single finger. At the same time, the transmission ratio is precise, and the pressing stroke corresponds strictly to the shaft angle, ensuring that when the pressing reaches the end of the stroke, the shaft rotates to the fully unlocked angle, ensuring accurate unlocking.

[0039] Furthermore, the inner side of the reset installation stepped hole 18 is provided with symmetrically distributed limiting grooves 19, and the outer side of the reset drive slide 8 is fixedly connected with symmetrically distributed limiting bosses 20. The limiting bosses 20 slide within the limiting grooves 19. The limiting grooves 19 are symmetrically opened on both sides of the inner wall of the reset installation stepped hole 18, and the groove walls are flat and smooth. The limiting bosses 20 symmetrically protrude from the outer wall of the reset drive slide 8. The shape of the bosses is precisely matched with the cross section of the groove, and they slide vertically along the groove. The two work together to form an anti-rotation guide structure, which can strictly limit the degree of freedom of movement of the reset drive slide, so that it can only move up and down in a straight line along the axis and will not rotate circumferentially with the steering axis, ensuring that there is no twisting or swaying during the pressing process and the operation feel is stable. At the same time, the upper and lower end faces of the groove can form a stroke limit for the limiting bosses, limiting the maximum rising height and maximum pressing depth of the reset drive slide.

[0040] Furthermore, a reset adjustment groove 30 is provided on the inner top of the fiber optic patch cord pigtail SC connector 1. The reset adjustment groove 30 is interconnected with the reset mounting stepped hole 18 and the adjustment connecting hole 11. A reset steering mechanism is provided on the inner side of the reset adjustment groove 30. The reset adjustment groove 30 is horizontally opened on the inner top of the fiber optic patch cord pigtail SC connector 1 and is vertically connected to the reset mounting stepped hole 18 on the top and the adjustment connecting holes 11 on both sides. The mounting cover 14 is a flat sealing cover plate, which is fixedly embedded in the bottom of the reset adjustment groove to seal and separate the transmission cavity from the fiber cavity below. This can prevent dust and moisture from entering the transmission mechanism and prevent lubricating oil from dripping and contaminating the fiber end face. A parallel guide groove is provided on the top surface of the cover to provide sliding support and guidance for the drive adapter slide plate, ensuring that the slide plate moves only in a horizontal straight line with a precise and unbiased movement trajectory. The closed transmission cavity design can protect the internal precision gear and rack transmission pair, prevent foreign objects from entering and causing jamming, and ensure the reliability of the long-term plugging and unplugging cycle operation.

[0041] Furthermore, the reset steering mechanism includes a mounting cover 14, a drive gear 24, a transmission gear 25, a drive adapter slide plate one 26, and a drive adapter slide plate two 27. The mounting cover 14 is fixedly connected to the inner side of the reset adjustment groove 30. The drive adapter slide plate one 26 and the drive adapter slide plate two 27 are slidably connected to the top surface of the mounting cover 14. The transmission gear 25 is fixedly connected to the sides of the drive adapter slide plate one 26 and the drive adapter slide plate two 27. The drive gear 24 is rotatably connected to the top surface of the mounting cover 14. The drive gear 24 meshes with the transmission gear 25. The inner side of the drive gear 24 is fixedly connected to the bottom of the steering shaft 23. A snap-fit ​​slide plate one 12 is fixedly connected to one end of the drive adapter slide plate one 26, and a snap-fit ​​slide plate two 17 is fixedly connected to one end of the drive adapter slide plate two 27. Gear 24 is fixed to the bottom end of steering shaft 23 and rotates synchronously with the shaft. The gear teeth are precision small module teeth, which ensure smooth transmission and small backlash. Drive adapter slide 1 26 and drive adapter slide 27 are symmetrically arranged on both sides of the gear. The inner transmission gear platform 25 meshes with the drive gear to form a double rack synchronous transmission structure. When the gear rotates, it can drive the two slides to move synchronously in opposite directions, ensuring that the unlocking and locking actions of the double-sided locking slides are completely synchronized and there will be no problem of asynchronous unlocking on one side. The outer ends of the two drive adapter slides are respectively connected to locking slide 1 and locking slide 2, which converts the rotational motion of the gear into the radial linear motion of the slide. A single input can synchronously drive the double-sided locking mechanism to unlock. The transmission structure is compact and efficient. Only one pressing point is needed to achieve full unlocking, and the operation steps are extremely simple.

[0042] Working principle: When this invention is used, and the operator aligns the fiber optic patch cord pigtail SC connector 1 with the equipment connector 4 and pushes it forward, the guide boss 6, fixedly connected to the top surface of the SC connector, first enters the connector guide hole 5 opened on the top surface of the equipment connector. A precise sliding fit is formed between the guide boss and the connector guide hole, ensuring that the entire SC connector can only move linearly along the axial direction of the connector guide hole, preventing radial wobble or angular tilt. This guiding mechanism ensures that the plug head 9, fixedly connected to the side of the fiber optic connector 13, can enter the inner side of the equipment connector with the completely correct posture and angle. The fiber optic connector is positioned so that it effectively avoids damage to the fiber end face or bending deformation of the ferrule caused by misalignment of the insertion angle. It also provides a precise positional reference for subsequent locking. After the guiding and positioning is completed, the SC connector continues to advance into the device connector, entering the locking stage. The insertion end of the fiber optic patch cord pigtail SC connector 1 is fixedly connected to rectangularly spaced locking guide ramps 15. The locking guide ramps 15 have a sloped structure that is lower at the front and higher at the back. During insertion, the front slope of the locking guide ramps 15 first connects to the symmetrically distributed insertion springs fixedly connected to the inner side of the device connector 4. When the SC connector is inserted into the optical fiber connector 28, the inclined surface exerts a gradually increasing outward pushing force on the elastic connector, causing the elastic connector to open elastically. Simultaneously, symmetrically distributed locking adjustment grooves 10 are provided on both sides of the optical fiber connector 13 inside the SC connector. Each locking adjustment groove contains linearly equidistant locking miniature springs 16. Locking slide plate one 12 and locking slide plate two 17 are slidably connected to the locking adjustment grooves on both sides, with their sides fixedly connected to the locking miniature springs 16. During the insertion of the SC connector into the equipment connector, the locking slide... Under the compression of the insertion elastic locking platform, plate 12 and the second locking plate 17 overcome the elastic force of the locking miniature spring 16 and retract inward. When the SC connector is pushed to the final locking position, the outer end faces of the first locking plate 12 and the second locking plate 17 just pass the locking protrusion of the insertion elastic locking platform 28. At this time, the locking miniature spring 16 releases its elastic potential energy, pushing the first locking plate 12 and the second locking plate 17 to return to their original position and pop outward, forming a firm locking relationship with the insertion elastic locking platform. This ensures that the SC connector can maintain a stable connection when subjected to axial tension or vibration impact, and will not accidentally loosen.

[0043] When the SC connector needs to be removed from the device connector, the operator presses the reset drive mechanism. The top surface of the fiber optic patch cord pigtail SC connector 1 is fixedly connected to a reset adjustment platform 7. The top surface of the reset adjustment platform 7 has a reset installation stepped hole 18. The reset drive slide 8 is slidably installed in the stepped hole, and its top surface is exposed outside the SC connector for finger pressing. When the operator presses down on the reset drive slide, the reset drive slide 8 slides down along the inner wall of the reset installation stepped hole 18, and at the same time compresses the reset spring 21 set inside the reset installation stepped hole 18, so that the reset spring 21 stores elastic potential energy. In this process, in order to ensure that the reset drive slide can only move linearly along the axial direction and does not rotate, the inner side of the reset installation stepped hole 18 has symmetrically distributed limiting grooves 19. The outer side of the reset drive slide 8 is fixedly connected to symmetrically distributed limiting bosses 20. The limiting bosses 20 are embedded in the limiting grooves 19 and slide along their guide, thereby constraining the movement direction of the reset drive slide.

[0044] The inner side of the reset drive slide 8 is fixedly connected with symmetrically distributed steering drive bosses 29, while the outer side of the steering shaft 23 is provided with symmetrically distributed steering thread grooves 22. The steering drive bosses 29 are embedded in the steering thread grooves 22 and slide along their spiral trajectory. When the reset drive slide 8 moves downward in a straight line, the steering drive bosses 29 slide along the spiral surface of the steering thread grooves 22, generating a tangential driving torque on the steering shaft, which forces the steering shaft 23 to rotate around its own axis inside the reset mounting stepped hole 18. The rotation angle of the steering shaft 23 and the pressing stroke of the reset drive slide 8 have a precise spiral transmission correspondence, ensuring that the pressing stroke can fully drive the subsequent unlocking mechanism to the unlocking completion position.

[0045] A reset adjustment groove 30 is provided on the inner top of the fiber optic patch cord pigtail SC connector 1. The reset adjustment groove 30 is interconnected with the reset mounting stepped hole 18 and the adjustment communication hole 11. A mounting cover 14 is fixedly connected to the inner side of the reset adjustment groove 30. A drive adapter slide plate 1 26 and a drive adapter slide plate 27 are slidably connected to the top surface of the mounting cover 14. A transmission gear platform 25 is fixedly connected to the side of each of the two drive adapter slide plates. A drive gear 24 is rotatably connected to the top surface of the mounting cover 14. The inner side of the drive gear 24 is fixedly connected to the bottom of the steering shaft 23. Therefore, when the steering shaft 23 rotates, it drives the drive gear 24 to rotate synchronously. The drive gear 24 simultaneously meshes with the transmission gear platforms on the sides of the drive adapter slide plate 1 26 and the drive adapter slide plate 27. Since the two drive adapter slide plates are respectively set on both sides of the drive gear, the rotational motion of the gear is converted into... Two sliding plates slide in opposite directions. One end of the drive adapter sliding plate 1 26 is fixedly connected to the snap-fit ​​sliding plate 1 12, and one end of the drive adapter sliding plate 27 is fixedly connected to the snap-fit ​​sliding plate 2 17. The two drive adapter sliding plates pass through the adjustment connecting hole 11 and are fixedly connected to their respective snap-fit ​​sliding plates. When the drive gear rotates, the drive adapter sliding plate 1 and the drive adapter sliding plate 2 drive the snap-fit ​​sliding plate 1 and the snap-fit ​​sliding plate 2 to slide in opposite directions along the snap-fit ​​adjustment slide groove 10. That is, the two snap-fit ​​sliding plates retract inward at the same time, compressing the snap-fit ​​micro spring 16, so that the outer end faces of the snap-fit ​​sliding plate 1 and the snap-fit ​​sliding plate 2 disengage from the snap-fit ​​locking position with the insertion elastic locking platform 28. At this time, all snap-fit ​​constraints between the SC connector and the equipment connector are released, and the operator can easily pull the SC connector out of the equipment connector axially without having to insert fingers into the narrow gap to operate.

[0046] After the pull-out operation is completed, when the operator releases the pressure on the reset drive slide 8, the entire mechanism enters the automatic reset stage. The compressed reset spring 21 releases its stored elastic potential energy, pushing the reset drive slide to slide upward along the reset mounting stepped hole 18 to reset. When the reset drive slide moves upward, the steering drive boss 29 on its inner side slides in the opposite direction along the steering thread groove 22, driving the steering shaft 23 to rotate in the opposite direction. The steering shaft drives the drive gear 24 to rotate in the opposite direction. The drive gear drives the drive transition slide plate 1 26 and the drive transition slide plate 27 to slide in the opposite direction through the transmission gear plate 25. This causes the locking slide plate 1 12 and the locking slide plate 2 17 to open outward under the auxiliary elastic force of the locking miniature spring 16, returning to the initial extended position.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
