[0002] In fiber optic communication networks, the fiber distribution box is a crucial component, primarily used for fiber distribution, splicing, and protection. With the rapid development of fiber optic networks, the requirements for fiber distribution boxes are becoming increasingly stringent, demanding higher reliability, flexibility, and ease of maintenance.

[0003] Existing fiber distribution boxes typically consist of the following parts:

[0004] Enclosure: Used to house and protect fiber optic connection components.

[0005] Fiber optic splice assemblies: including pigtails, straight connectors, etc., are used to achieve physical connections of optical fibers.

[0006] Jumper management component: Used to manage and fix jumpers, preventing jumper mess.

[0007] Existing fiber optic distribution boxes lack flexibility, making them difficult to adjust or maintain once installed.

[0037] The combination of hinge 10 and bolts provides flexibility and stability, allowing the cover 6 to be opened and closed easily while maintaining a secure connection. Threaded connection holes on the mating block 12 ensure a more precise fit between the housing 1 and the cover 6, improving overall sealing and durability.

[0038] Specifically, a locking block 13 is provided on one side of the docking block 12 on the housing 1, and a locking groove 14 is provided on the cover 6 to engage with the locking block 13. The design of the locking block 13 and the locking groove 14 allows for quick and accurate docking of the housing 1 and the cover 6, improving installation speed. The engagement of the locking block 13 and the locking groove 14 increases the stability of the connection and prevents the cover 6 from shifting during use. This design makes the opening and closing of the housing 1 and the cover 6 more convenient, facilitating maintenance and repair.

[0039] Specifically, the upper and lower ends of the housing 1 are provided with mounting positions 15 for installation and fixation. The mounting positions 15 have straight slots, which provide multiple installation methods to adapt to different installation environments.

[0040] Specifically, the mounting frame 4 includes two rotating connecting seats A16 fixed at both ends of the inner side of the rectangular concave groove 2 and located at the upper end of the pigtail box 3, a support plate 17 rotatably connected to the two rotating connecting seats A16, a frame plate 18 fixed on the support plate 17 and fitted with a straight connector, and a guide plate 19 fixed inside the support plate 17; the guide plate 19 has several rows of guide holes C20, and the support plate 17 has wire through holes 21.

[0041] Two rotating connecting seats A16 are fixed at both ends of the inner side of the rectangular concave groove 2, allowing for rotatable connection to the support plate 17. This design provides flexibility, allowing the support plate 17 to be flipped as needed, facilitating the installation and maintenance of the straight connector. The support plate 17 and the frame plate 18 fixed thereon can be engaged with the straight connector for secure installation. This design makes the installation of the straight connector more secure, while the frame plate 18 provides additional protection against accidental impacts or damage to the straight connector. The guide hole C20 on the guide plate 19 guides the jumper wires, ensuring they are arranged along a predetermined path, avoiding interference between jumper wires, and facilitating jumper wire management and maintenance. The wire pass-through hole 21 on the support plate 17 allows the jumper wires to pass through the back of the support plate 17, helping to keep the jumper wires neat and orderly and reducing their footprint on the operating space.

[0042] Specifically, the multi-layer flip-type guide box 5 includes several lead wire boxes 22 stacked together and corresponding to each row of guide holes. Each lead wire box 22 includes an upper box body 221 and a lower box body 222 that interlock to form several circular channels 23. A rotating connecting seat B24 is provided within a rectangular concave groove 2 to rotatably connect the upper box body 221 and the lower box body 222.

The frame plate 18 abutting against the inner wall of the cover 6 increases the stability of the connection between the cover 6 and the enclosure 1, reducing the risk of displacement of the frame plate 18 due to external forces. The design of the frame plate 18 makes full use of the space inside the enclosure 1, keeping the interior clean and orderly, and facilitating maintenance and operation.

[0044] This detachable and modular fiber distribution box, through the cooperation of the box body 1 and the box cover 6, provides protection and support for the distribution and splicing of optical fibers. The rectangular concave groove 2 inside the box body 1 is used to install the pigtail box 3, the mounting bracket 4, and the multi-layer flip-type guide box 5. The pigtail box 3 connects the optical cable core to the pigtail, the mounting bracket 4 fixes the straight connector to ensure its stability, and the multi-layer flip-type guide box 5 is responsible for guiding and sorting patch cords, avoiding interference and damage between optical fibers. The guide hole A8 at the bottom and the guide hole B9 at the top of the box body 1 provide guiding paths for the optical cable and the user-end optical fiber cable, respectively, ensuring correct connection and orderly management of the optical fibers.

[0045] Compared to existing technologies, this modular fiber distribution box design addresses the shortcomings of traditional fiber distribution boxes in terms of maintenance, flexibility, and patch cord management. Traditional fiber distribution boxes often lack effective patch cord guidance and management systems, leading to patch cord clutter, increased signal loss, and inconvenient maintenance and repair. Furthermore, existing fiber distribution boxes may have limited installation options, poor adaptability, and insufficient sealing and stability.

[0046] Its detachable and assembleable design improves maintenance efficiency. The independent disassembly and assembly of the pigtail box 3, straight connector, and patch cord facilitates independent disassembly and maintenance of the pigtail box 3, straight connector, and patch cord. The flexibility of the enclosure 1 and the multi-layer flip-type guide box 5 greatly improve the management efficiency of patch cords and reduce signal loss and fiber damage. The multiple installation methods of the enclosure 1 enhance adaptability, and the straight slot design ensures the stability of the fiber distribution box after installation, improving the reliability of fiber optic connections.
