[0002] In the field of optical fiber communication, optical fiber connectors are key components for achieving stable and efficient connections between optical fibers, and their performance directly affects the quality and reliability of optical signal transmission. With the rapid development of optical fiber communication technology, higher demands are placed on the assembly efficiency, connection stability, and ease of maintenance of optical fiber connectors. The traditional guide pin mounting structure of optical fiber connectors has many limitations. During assembly, complex tools and cumbersome procedures are usually required to align the optical fiber plug with the connector. When maintenance or replacement of the optical fiber plug is needed, the disassembly process of the traditional structure is extremely difficult. It often requires disassembling multiple components and using special tools to remove the optical fiber plug, and is also prone to damaging the optical fiber connector and optical fiber during disassembly. Summary of the Invention

[0003] The purpose of this invention is to provide a guide pin mounting structure for optical fiber communication, addressing the numerous limitations of traditional guide pin mounting structures for optical fiber connectors as described in the background section. During assembly, complex tools and cumbersome procedures are typically required to connect the optical fiber connector to the connector. Furthermore, the disassembly process of traditional structures is extremely difficult when maintaining the optical fiber connector or replacing the optical fiber connector. It often requires disassembling multiple components and using special tools to remove the optical fiber connector, and is prone to damaging the optical fiber connector and optical fiber during disassembly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a guide pin mounting structure for optical fiber communication, comprising: Fiber optic connectors; The bottom fixing frame is located at the bottom of the fiber optic connector; The fiber optic connector is located below the fiber optic connector and mates with the bottom fixing frame. The guide pin body is symmetrically arranged inside the optical fiber connector, and the optical fiber connector has a connector seat that mates with the guide pin body. The first outer limiting plate is fixed to one of the two sides of the optical fiber connector, and the other two sides of the optical fiber connector are fixed to the second outer limiting plate. The second positioning groove is symmetrically opened on the inner side of the bottom fixed frame, and the second positioning groove cooperates with the second outer limiting plate. The mounting part is located inside the bottom fixing frame, and the outer side of the second outer limiting plate is provided with a limiting slot that cooperates with the mounting part.

[0005] As a preferred embodiment of this utility model: the mounting part includes an inner sliding plate, a limiting block, and a fixed side plate. Two inner sliding plates are symmetrically slidably arranged inside the bottom fixed frame. A limiting block that cooperates with the limiting slot is fixedly connected to one side of the inner sliding plate. A fixed side plate is fixedly connected to the side of the inner sliding plate away from the limiting block. The fixed side plate is slidably connected to the bottom fixed frame.

[0006] As a preferred embodiment of this utility model: two external grooves are symmetrically provided on the outer side of the bottom fixing frame, and a sloping pull plate is fixedly connected to the side of the fixing side plate away from the inner sliding plate.

[0007] As a preferred embodiment of this utility model: two limiting rods are symmetrically slidably arranged inside the inner sliding plate, the limiting rods are fixedly connected to the bottom fixing frame, and two springs are symmetrically arranged on one side of the inner sliding plate, one end of the spring is connected to the bottom fixing frame, and the other end of the spring is connected to the inner sliding plate.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 6 This utility model provides a technical solution: a guide pin mounting structure for optical fiber communication, comprising: an optical fiber connector 1; a bottom fixing frame 2 fixedly connected to the bottom of the optical fiber connector 1; an optical fiber connecting plug 3 placed below the optical fiber connector 1, the optical fiber connecting plug 3 cooperating with the bottom fixing frame 2; guide pin bodies 4 symmetrically arranged inside the optical fiber connecting plug 3, and a connecting seat cooperating with the guide pin body 4 provided inside the optical fiber connector 1; a first outer limiting plate 5 fixedly connected to one of the two sides of the optical fiber connecting plug 3, and a second outer limiting plate 6 fixedly connected to the other two sides of the optical fiber connecting plug 3; a second positioning groove 7 symmetrically opened on the inner side of the bottom fixing frame 2, the second positioning groove 7 cooperating with the second outer limiting plate 6; an installation part arranged inside the bottom fixing frame 2, and a limiting slot 10 cooperating with the installation part opened on the outer side of the second outer limiting plate 6.

[0015] It should be noted that in this embodiment, when installing the fiber optic connector 3, the fiber optic connector 3 is first inserted downwards, aligned with the installation position of the bottom fixing frame 2. The first outer limiting plate 5 and the second outer limiting plate 6 on both sides of the fiber optic connector 3 are respectively embedded in the first positioning groove 8 and the second positioning groove 7 on the inner side of the bottom fixing frame 2, forming a preliminary four-way limiting to prevent the connector from rotating or shifting in the horizontal plane. During the insertion process, the guide inclined groove 9 on the outer side of the second outer limiting plate 6 contacts and interacts with the inclined surface 13 on the limiting block 12. As the fiber optic connector 3 continues to be pressed down, the inclined surface 13 slides along the guide inclined groove 9, pushing the limiting block 12 to move outwards, thereby causing the inner sliding plate 11 to overcome the elastic force of the spring 16 and slide along the limiting rod 15, so that the limiting block 12 temporarily retracts, providing space for the smooth insertion of the fiber optic connector 3. After the connector 3 is fully inserted, the guide groove 9 disengages from the inclined surface 13. Under the action of the elastic restoring force, the spring 16 pushes the inner sliding plate 11 to reset, so that the limit block 12 automatically engages in the limit slot 10 on the second outer limit plate 6, achieving reliable locking. At the same time, the outer connector 17 at the bottom of the fiber optic connector 3 fits tightly with the inner side of the bottom fixing frame 2, further ensuring axial positioning accuracy, so that the guide pin 4 inside the fiber optic connector 3 can be accurately aligned with the connector in the fiber optic connector 1, ensuring low-loss transmission of optical signals. When disassembly is required, the user only needs to pull the inclined pull plate 19 from the outer groove 18 on the outside of the bottom fixing frame 2 inward, which will drive the fixed side plate 14, the inner sliding plate 11 and the limit block 12 to slide synchronously, so that the limit block 12 disengages from the limit slot 10, thereby easily removing the fiber optic connector 3, realizing quick maintenance or replacement.

[0016] In one embodiment, such as Figures 2 to 6 As shown, the installation part includes an inner sliding plate 11, a limiting block 12, and a fixed side plate 14. Two inner sliding plates 11 are symmetrically slidably arranged inside the bottom fixed frame 2. A limiting block 12 that cooperates with the limiting slot 10 is fixedly connected to one side of the inner sliding plate 11. A fixed side plate 14 is fixedly connected to the side of the inner sliding plate 11 away from the limiting block 12. The fixed side plate 14 is slidably connected to the bottom fixed frame 2.

[0017] It should be noted that, in this embodiment, by setting an installation part including an inner sliding plate 11, a limiting block 12 and a fixed side plate 14, the limiting block 12 can quickly engage and unlock with the limiting slot 10, thereby improving the installation stability and disassembly convenience of the fiber optic connector 3 in the bottom fixed frame 2.

[0018] In one embodiment, such as Figures 1 to 6 As shown, two external grooves 18 are symmetrically opened on the outer side of the bottom fixed frame 2, and a sloping pull plate 19 is fixedly connected to the side of the fixed side plate 14 away from the inner sliding plate 11.

[0019] It should be noted that in this embodiment, an outer groove 18 is provided on the outside of the bottom fixed frame 2, and an inclined pull plate 19 is fixed on the fixed side plate 14, so that the user can pull the inclined pull plate 19 from the outer groove 18 with his / her fingers or tools, thereby driving the inner sliding plate 11 to slide, realizing the quick separation of the limiting card block 12 and the limiting card groove 10, which significantly improves the efficiency of maintenance and replacement of fiber optic connector 3.

[0020] In one embodiment, such as Figures 3 to 6 As shown, two limiting rods 15 are symmetrically slidably arranged inside the inner sliding plate 11. The limiting rods 15 are fixedly connected to the bottom fixed frame 2. Two springs 16 are symmetrically arranged on one side of the inner sliding plate 11. One end of the spring 16 is connected to the bottom fixed frame 2, and the other end of the spring 16 is connected to the inner sliding plate 11.

[0021] It should be noted that in this embodiment, by setting a limiting rod 15 inside the inner sliding plate 11 and fixing it to the bottom fixed frame 2, the sliding trajectory of the inner sliding plate 11 is effectively limited, preventing it from deviating or shaking; at the same time, in conjunction with the elastic reset effect of the spring 16, the limiting block 12 is always in a locked state without external force, which enhances the reliability of the connection structure for long-term use.

[0022] In one embodiment, such as Figures 1 to 6 As shown, a sloping surface 13 is provided on one side of the limiting block 12, and a guide sloping groove 9 that cooperates with the sloping surface 13 is provided on the outer side of the second outer limiting plate 6.

[0023] It should be noted that in this embodiment, the inclined surface 13 on the limiting block 12 and the guide inclined groove 9 on the second outer limiting plate 6 cooperate with each other. During the insertion of the optical fiber connector 3, the limiting block 12 can be automatically guided to slide outward and compress the spring 16. After it is in place, it will automatically spring back and lock into the limiting groove 10, realizing the self-aligning installation function of locking as soon as it is pushed in.

[0024] In one embodiment, such as Figures 1 to 4 As shown, two positioning slots 8 are symmetrically opened on the inner side of the bottom fixing frame 2 to cooperate with the first outer limiting plate 5. The bottom of the fiber optic connector 3 is provided with an outer connector 17, and the inner side of the outer connector 17 cooperates with the bottom fixing frame 2.

[0025] It should be noted that in this embodiment, by setting a first positioning groove 8 that cooperates with the first outer limiting plate 5 on the inner side of the bottom fixed frame 2, and combining the cooperation of the second positioning groove 7 with the second outer limiting plate 6, a four-way limiting structure is formed, which effectively prevents the optical fiber connector 3 from rotating or shifting in the horizontal plane.
