Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to a pull-out optical fiber distribution box. Background Technology

[0002] Fiber optic distribution boxes, as key node equipment in fiber optic communication cable networks, are deployed at terminals or repeater points to realize fiber routing, patching, fiber optic splicing, and access functions, and undertake the tasks of fixing, splicing, allocating, and storing optical fibers. This equipment is a standard configuration in high-density fiber optic connection environments such as data centers, communication equipment rooms, and enterprise networks.

[0003] In related technologies, fiber optic distribution boxes consist of a box body and a distribution tray. The distribution tray is installed inside the box via a sliding mechanism such as a slide rail, allowing for partial or complete removal for maintenance operations such as patching and wiring. However, this design has operational limitations. Users may accidentally pull the entire distribution tray out of the box during the removal process. Since only a small number of operations, such as replacing parts, require the tray to be completely removed, most patching operations only require partial removal. When the tray is fully removed during these operations, the operator has to hold the tray while performing the operation, and after the operation, the distribution tray must be repositioned back into the box, making the operation process cumbersome and reducing work efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a pull-out fiber optic distribution box, which allows the distribution tray to be suspended when pulled out to facilitate distribution operations and improve the efficiency of distribution work.

[0005] To achieve the above objectives, the present invention proposes a pull-out fiber optic distribution box comprising a box body and a distribution tray. A receiving cavity is formed within the box body, and an opening is formed on the box body connecting the receiving cavity to the outside. A limiting groove extending along the direction from the opening to the receiving cavity is provided on the inner wall of the receiving cavity. The distribution tray extends through the opening into the receiving cavity and is slidably connected to the box body. An elastic stop mechanism is formed on the distribution tray. The elastic stop mechanism is confined within the limiting groove and is configured to elastically deform upon being pressed to disengage from the limiting groove.

[0006] In one embodiment, the elastic stop mechanism includes a spring arm and a stop protrusion disposed on the spring arm; the spring arm is connected to the outer wall of the wiring tray, and the stop protrusion is limited within the limiting groove; the spring arm is configured to elastically deform when pressed to drive the stop protrusion out of the limiting groove.

[0007] In one embodiment, the stop protrusion has an abutment surface and a guide surface; the abutment surface is located on the side of the stop protrusion closest to the opening and abuts against the inner wall of the limiting groove, and the guide surface is located on the side of the stop protrusion furthest from the opening.

[0008] In one embodiment, the elastic arm has an arcuate protrusion that protrudes in a direction away from the wiring tray.

[0009] In one embodiment, a snap-fit ​​groove is formed between the arc-shaped protrusion and the stop protrusion, and a snap-fit ​​protrusion is formed at one end of the limiting groove near the opening, the snap-fit ​​protrusion being limited to the snap-fit ​​groove.

[0010] In one embodiment, the outer side wall of the wiring tray is provided with a slide bar, the inner side wall of the receiving cavity is provided with a slide rail, a slide groove is formed on the slide rail, and the slide bar is slidably connected to the inner wall of the slide groove.

[0011] In one embodiment, the slide bar is provided with the elastic stop mechanism, and the bottom wall of the slide groove is provided with the limiting groove; the elastic stop mechanism includes a spring arm and a stop protrusion provided on the spring arm, both ends of the spring arm are connected to the slide bar, a clearance hole is formed between the spring arm and the slide bar, and the stop protrusion is provided on the side of the spring arm opposite to the clearance hole.

[0012] In one embodiment, the slide bar is further provided with a positioning groove, and an elastic cantilever is provided in the groove. The free end of the elastic cantilever is formed with a positioning protrusion, which is used to engage with the inner wall of the positioning groove to prevent the wiring tray from sliding relative to the housing.

[0013] In one embodiment, the top wall of the wiring tray has a receiving groove, and the receiving groove is provided with a fiber optic adapter holder. The fiber optic adapter holder divides the receiving groove into a fiber storage groove and a distribution groove. The side wall of the distribution groove is provided with an inlet and an outlet. One end of the wiring tray near the fiber storage groove extends into the receiving cavity through the opening, and the other end of the wiring tray near the distribution groove is located outside the receiving cavity.

[0014] In one embodiment, the top wall of the wiring tray is further provided with a connecting channel; the edge of the wiring tray is also provided with a through notch, which penetrates the wiring tray along the direction from the top wall to the bottom wall of the wiring tray; the connecting channel connects the fiber storage groove and the through notch.

[0015] This utility model proposes a pull-out fiber optic distribution box, comprising a box body and a distribution tray. The box body has a receiving cavity, and the box body has an opening connecting the receiving cavity to the outside. A limiting groove extending from the opening into the receiving cavity is provided within the receiving cavity. The distribution tray extends through the opening into the receiving cavity and is slidably connected to the box body. An elastic stop mechanism is formed on the distribution tray. The elastic stop mechanism is confined within the limiting groove and is configured to elastically deform upon being pressed, thus disengaging from the limiting groove. This utility model, by providing an elastic stop mechanism on the distribution tray and a limiting groove that cooperates with the elastic stop mechanism on the inner wall of the receiving cavity, allows for flexible operation during wiring, where the distribution tray does not need to be completely removed. In this case, pulling the distribution tray restricts the elastic stop mechanism's movement to within the limiting groove, preventing it from disengaging. When the distribution tray is pulled out to its maximum stroke, the elastic stop mechanism abuts against the side wall of the limiting groove to prevent the distribution tray from detaching from the box body, at which point the distribution tray is in a suspended state. When operations such as replacing fiber jumpers are required, i.e., when the wiring tray needs to be completely removed, press the elastic stop mechanism to cause it to deform elastically and disengage from the limiting groove. At this time, the wiring tray can be pulled further to remove it from the box. Therefore, the technical solution of this utility model not only allows the wiring tray to be suspended when partially pulled out for easy adjustment operations, improving the efficiency of adjustment work, but also retains the function of the wiring tray being able to be pulled out of the box, thus having good applicability and convenience.

[0036] This utility model proposes a pull-out fiber optic distribution box 100.

[0037] Please see Figures 2 to 4 In one embodiment of the present invention, the pull-out fiber optic distribution box 100 includes a box body 1 and a distribution tray 2. A receiving cavity 1a is formed inside the box body 1, and an opening 1b is formed on the box body 1 to connect the receiving cavity 1a with the outside. The inner wall of the receiving cavity 1a is provided with a limiting groove 11b extending along the direction from the opening 1b to the receiving cavity 1a. The distribution tray 2 extends into the receiving cavity 1a through the opening 1b and is slidably connected to the box body 1. An elastic stop mechanism 22 is formed on the distribution tray 2. The elastic stop mechanism 22 is limited within the limiting groove 11b, and the elastic stop mechanism 22 is configured to elastically deform and disengage from the limiting groove 11b after being pressed.

[0038] Specifically, please refer to Figure 3In this embodiment, the housing 1 includes a top cover 12 and a bottom box 13. The top cover 12 is a plate-like structure, and the bottom box 13 is a box-shaped structure with an opening at the top and an opening 1b on one side wall. The top cover 12 is placed over the opening at the top of the bottom box 13 and is detachably connected to the bottom box 13 by screws. The top cover 12 and the bottom box 13 together form a receiving cavity 1a. Optionally, the bottom box 13 is formed by folding a sheet metal structure.

[0039] The sidewall of the wiring tray 2 has an elastic stop mechanism 22, and the receiving cavity 1a has a limiting groove 11b adapted to the elastic stop mechanism 22. Optionally, a strip-shaped protrusion can be welded to the inner sidewall of the receiving cavity 1a to form a groove-like structure, and a limiting block or limiting plate can be provided at one end of the groove-like structure near the opening 1b to form the sidewall of the groove-like structure. Thus, the groove-like structure is the limiting groove 11b, and its length direction is consistent with the sliding direction of the wiring tray 2. The sidewall of the limiting groove 11b has a certain thickness to provide a limiting function for the elastic stop mechanism 22. Optionally, the structure of the elastic stop mechanism 22 is an elastic sheet, one end of which is fixed to the wiring tray 2, and the other end is a free end that extends into the limiting groove 11b. Because the elastic sheet has a certain elastic deformation capacity, the free end can undergo a certain displacement when the elastic sheet is deformed by external force, thereby disengaging from the limiting groove 11b. The spring can be made of metal or plastic with good elasticity. For example, the spring can be made of plastic and integrally molded with the wiring tray 2. This simplifies the assembly process between components and strengthens the overall integrity of the wiring tray 2 and the elastic stop mechanism 22. When not subjected to external force, the elastic stop mechanism 22 can slide within the limiting groove 11b. When pulled to its maximum sliding stroke, the free end abuts against the side wall of the limiting groove 11b, thereby limiting the sliding stroke of the wiring tray 2. At this time, the wiring tray 2 is suspended on the housing 1 and cannot be completely pulled out of the housing 1 (e.g., Figure 2 , Figure 5 (As shown). When it is necessary to completely pull out the wiring tray 2, the elastic stop mechanism 22 is pressed to cause it to deform elastically, so that the free end of the elastic stop mechanism 22 is disengaged from the limiting groove 11b. At this time, the wiring tray 2 can continue to slide and be completely pulled out of the box 1.

[0040] In summary, this embodiment achieves the suspension function of the wiring tray 2 when partially withdrawn through the cooperation of the elastic stop mechanism 22 and the limiting groove 11b. When the elastic stop mechanism 22 is confined within the limiting groove 11b, the wiring tray 2 is restricted within the housing 1 and cannot be fully withdrawn, thus facilitating dispatching operations. When the elastic stop mechanism 22 is pressed and disengaged from the limiting groove 11b, the wiring tray 2 can be fully withdrawn to meet the needs of operations such as replacing jumpers. This design improves dispatching efficiency while retaining the function of the wiring tray 2 being withdrawable from the housing 1, exhibiting good applicability and convenience.

[0041] Further, please refer to Figure 6 and Figure 11 In one embodiment of the present invention, the elastic stop mechanism 22 includes an elastic arm 221 and a stop protrusion 222 disposed on the elastic arm 221; the elastic arm 221 is connected to the outer wall of the wiring tray 2, and the stop protrusion 222 is limited within the limiting groove 11b; the elastic arm 221 is configured to undergo elastic deformation after being pressed to drive the stop protrusion 222 to disengage from the limiting groove 11b.

[0042] In this embodiment, the elastic arm 221 is an elastic strip structure, with at least one end fixedly connected to the outer wall of the wiring tray 2. The material of the elastic arm 221 can be a metal or high-strength plastic with good elastic properties, such as spring steel or nylon, to ensure that the elastic arm 221 can elastically deform when pressed and return to its original shape after the external force is released. Preferably, the elastic arm 221 and the wiring tray 2 are integrally molded to improve the integrity and connection strength of the elastic arm 221 and the wiring tray 2, reduce structural complexity, and avoid complicated assembly steps. The stop protrusion 222 is a protrusion on the elastic arm 221, which can be circular or square in shape, and its size matches the width of the limiting groove 11b. The material of the stop protrusion 222 can be the same as that of the elastic arm 221, and the two can be integrally molded to reduce structural complexity, improve integrity, and reduce installation steps. In this embodiment, the elastic arm 221 serves as a supporting structure and a structure that undergoes elastic deformation, providing elastic support for the stop protrusion 222. The stop protrusion 222 can extend into and be confined within the limiting groove 11b, thereby preventing the wiring tray 2 from sliding further when it is partially pulled out by abutting against the side wall of the limiting groove 11b, achieving a hovering function. When it is necessary to completely pull out the wiring tray 2, pressing the elastic arm 221 causes it to deform elastically, thereby causing the stop protrusion 222 to disengage from the limiting groove 11b, allowing the wiring tray 2 to continue sliding and be completely pulled out.

[0043] Further, please refer to Figure 6 In one embodiment of the present invention, the stop protrusion 222 has an abutment surface 2221 and a guide surface 2222; the abutment surface 2221 is located on the side of the stop protrusion 222 near the opening 1b and abuts against the inner sidewall of the limiting groove 11b, and the guide surface 2222 is located on the side of the stop protrusion 222 away from the opening 1b.

[0044] In this embodiment, the abutment surface 2221 is planar and fits tightly against the inner wall of the limiting groove 11b. When the wiring tray 2 is partially pulled out, the abutment surface 2221 abuts against the inner wall of the limiting groove 11b, preventing the wiring tray 2 from continuing to slide, thereby achieving a hovering function. The guide surface 2222 is inclined or curved and has a certain tilt angle, which facilitates the guide stop protrusion 222 to slide smoothly into the limiting groove 11b when the wiring tray 2 is pushed into the housing 1. The design of the guide surface 2222 makes the wiring tray 2 easier to install into the housing 1, reduces the resistance and difficulty of assembly, and makes the installation and removal of the wiring tray 2 smoother and more efficient.

[0045] Further, please refer to Figure 5 and Figure 11 In one embodiment of the present invention, an arc-shaped protrusion 2211 is formed on the elastic arm 221, and the arc-shaped protrusion 2211 protrudes in a direction away from the wiring tray 2.

[0046] In this embodiment, the bow-shaped protrusion 2211 is formed by bending the elastic arm 221, and its shape is bow-shaped. The bow-shaped protrusion 2211 is designed to amplify the deformation when the elastic arm 221 is pressed. When the bow-shaped protrusion 2211 is pressed, due to its arc-shaped structure, the fixed end of the elastic arm 221 will rotate and deform more. This design makes it easier for the stop protrusion 222 to disengage from the limiting groove 11b, thereby achieving complete removal of the wiring tray 2. The two sides of the bow-shaped protrusion 2211 form inclined arc surfaces or planes. As the wiring tray 2 is pulled out, the inner sidewall of the limiting groove 11b and the inner sidewall of the opening 1b can squeeze the bow-shaped protrusion 2211 to deform it. Therefore, the bow-shaped protrusion 2211 does not completely prevent the sliding of the wiring tray 2. In this embodiment, the bow-shaped protrusion 2211 makes the pressing and unlocking operation of the stop elastic structure easier and more convenient, thereby making the pulling out and pushing in process of the wiring tray 2 smoother and more efficient.

[0047] Further, please refer to Figure 6 and Figure 11 In one embodiment of the present invention, a snap-fit ​​groove 22a is formed between the arc-shaped protrusion 2211 and the stop protrusion 222, and a snap-fit ​​protrusion 111 is formed at one end of the limiting groove 11b near the opening 1b, and the snap-fit ​​protrusion 111 is limited to the snap-fit ​​groove 22a.

[0048] In this embodiment, the arc-shaped protrusion 2211 and the stop protrusion 222 are spaced apart. This not only enhances the elastic deformation capability of the elastic arm 221 using the arc-shaped protrusion 2211, but also forms a locking groove 22a between the arc-shaped protrusion 2211 and the stop protrusion 222. The shape of the locking groove 22a matches the locking protrusion 111, ensuring that the locking protrusion 111 is confined within the locking groove 22a. The locking protrusion 111 is located at one end of the limiting groove 11b near the opening 1b and protrudes from the bottom wall of the limiting groove 11b. Its shape is arc-shaped or square, etc., and its size matches the locking groove 22a. Preferably, in this embodiment, the locking protrusion 111 is integrated with the inner sidewall of the limiting groove 11b near the opening 1b, that is, the locking protrusion 111 forms an inner sidewall of the limiting groove 11b, achieving the effect of simplifying the structure. This embodiment features a snap-fit ​​groove 22a and a snap-fit ​​protrusion 111 located near the opening 1b of the limiting groove 11b. This design ensures that the snap-fit ​​protrusion 111 remains within the snap-fit ​​groove 22a when the wiring tray 2's pull-out stroke reaches its maximum, preventing the wiring tray 2 from sliding back and forth due to external forces during wiring operations while suspended. This design allows the wiring tray 2 to remain stable when suspended, facilitating wiring operations. Simultaneously, this design does not affect the complete pull-out and push-in operations of the wiring tray 2. When the wiring tray 2 needs to be completely pulled out, pressing the arc-shaped protrusion 2211 disengages the stop protrusion 222 from the limiting groove 11b, and the snap-fit ​​protrusion 111 also disengages from the snap-fit ​​groove 22a, allowing the wiring tray 2 to be completely pulled out. When it is necessary to release the suspended state and push the wiring tray 2 into the housing 1, the arc-shaped protrusion 2211 is pressed, or the tray is pushed with greater force (this force is greater than the force applied to the wiring tray 2 during wiring operations). This causes the elastic arm 221 forming the snap-fit ​​groove 22a to be compressed and deformed, thereby disengaging from the snap-fit ​​protrusion 111. That is, the arc-shaped protrusion 2211 and the remaining elastic arm 221 deform and move toward the wiring tray 2, thereby retracting into the opening 1b. Then, the wiring tray 2 can be pushed into the receiving cavity 1a. The arc-shaped protrusion 2211 enters the limiting groove 11b with the movement of the wiring tray 2 and restores its shape before deformation. Therefore, the process of completely pulling out and pushing in the wiring tray 2 is still smooth and efficient.

[0049] Further, please refer to Figure 3 In one embodiment of the present invention, the outer side wall of the wiring tray 2 is provided with a slide bar 21, the inner side wall of the receiving cavity 1a is provided with a slide rail 11, a slide groove 11a is formed on the slide rail 11, and the slide bar 21 is slidably connected to the inner wall of the slide groove 11a.

[0050] In this embodiment, to achieve a sliding connection between the wiring tray 2 and the housing 1, two opposing slide rails 11 are provided on the two inner sidewalls of the receiving cavity 1a adjacent to the opening 1b. Each slide rail 11 is connected to the inner sidewall of the receiving cavity 1a by screws. Further reference Figure 5 and Figure 8 The slide rail 11 has a groove 11a on the side facing the receiving cavity 1a, and the wiring tray 2 has slide bars 21 on both sides. The slide bars 21 can extend into the groove 11a to slide and connect with the inner wall of the groove 11a. In this way, the slide rail 11 can be disassembled and replaced for easy maintenance.

[0051] Further, please refer to Figure 5 , Figure 6 and Figure 11 In one embodiment of the present invention, the slide bar 21 is provided with an elastic stop mechanism 22, and the bottom wall of the slide groove 11a is provided with a limiting groove 11b; the elastic stop mechanism 22 includes an elastic arm 221 and a stop protrusion 222 provided on the elastic arm 221. Both ends of the elastic arm 221 are connected to the slide bar 21, and a clearance hole 21a is formed between the elastic arm 221 and the slide bar 21. The stop protrusion 222 is provided on the side of the elastic arm 221 facing away from the clearance hole 21a.

[0052] In this embodiment, the elastic stop mechanism 22 and the slide bar 21 are integrated into one unit, reducing structural complexity and making the layout of the elastic stop mechanism 22 on the slide bar 21 more compact, reducing the number of parts and assembly difficulty. Specifically, the elastic stop mechanism 22 includes a spring arm 221 and a stop protrusion 222 provided on the spring arm 221. The spring arm 221 and the slide bar 21 are integrally formed. The spring arm 221 is curved as a whole. Both ends of the spring arm 221 are connected to the side wall of the slide bar 21. The middle part of the spring arm 221 forms an arc-shaped protrusion 2211, and a clearance hole 21a is formed between the spring arm 221 and the slide bar 21. The design of the clearance hole 21a provides space for the elastic deformation of the spring arm 221. Furthermore, the range of the clearance hole 21a can be expanded so that the clearance hole 21a extends into the interior of the slide bar 21, so that part of the slide bar 21 is hollowed out, thereby expanding the clearance range. The setting of the clearance hole 21a ensures that the elastic arm 221 has enough deformation space so that the stop protrusion 222 can smoothly disengage from the limiting groove 11b when the elastic arm 221 is pressed, thereby realizing the extraction and insertion operation of the wiring tray 2.

[0053] The integrated design of the elastic stop mechanism 22 and the slide bar 21 in this embodiment reduces the risk of failure due to loose or detached components, further improving the reliability and service life of the fiber optic distribution box. This design simplifies the structure and optimizes the operation process, making the operation of the fiber optic distribution box more efficient and convenient.

[0054] Further, please refer to Figure 7 , Figure 8In one embodiment of the present invention, the slide bar 21 is further provided with a positioning groove 21b, and the slide groove 11a is provided with an elastic cantilever 112. The free end of the elastic cantilever 112 is formed with a positioning protrusion 1121. The positioning protrusion 1121 is used to engage with the inner wall of the positioning groove 21b to prevent the wiring tray 2 from sliding relative to the housing 1.

[0055] In this embodiment, the top and / or bottom walls of the slide bar 21 are provided with positioning grooves 21b, and the inner sidewall of the slide groove 11a is provided with an elastic cantilever 112. The free end of the elastic cantilever 112 has a positioning protrusion 1121, which is used to engage with the inner wall of the positioning groove 21b to prevent the wiring tray 2 from sliding relative to the housing 1. Specifically, the slide rail 11 can be made of process plastic with a certain elastic deformation capability. The elastic cantilever 112 is an integral structure with the slide rail 11. By providing a 7-shaped slot through the slide rail 11 on the inner sidewall of the slide groove 11a, an elastic cantilever 112 is formed on the inner sidewall of the slide groove 11a. When the wiring tray 2 is completely slid into the receiving groove 2a, the positioning protrusion 1121 engages elastically with the positioning groove 21b, thereby preventing the wiring tray 2 from automatically sliding out due to load or other reasons. This design further enhances the stability of the wiring tray 2 when it is completely pushed into the housing 1. Since the elastic cantilever 112 has a certain elastic deformation capability, when the wiring tray 2 needs to be pulled out, the elastic cantilever 112 can be elastically deformed by increasing the pulling force, thereby causing the positioning protrusion 1121 to disengage from the positioning groove 21b. This operation is simple and quick.

[0056] It should be noted that the number of positioning protrusions 1121 and positioning grooves 21b can be increased according to requirements. For example, multiple positioning grooves 21b can be provided in the length direction of the slide bar 21, or multiple elastic cantilevers 112 and positioning protrusions 1121 can be provided in the length direction of the slide groove 11a (e.g., Figure 10 As shown in the figure, in order to achieve multi-level positioning function and strengthen the elastic snap-fit ​​force, further improve the flexibility of use of the wiring tray 2.

[0057] Further, please refer to Figure 7 and Figure 11 In one embodiment of the present invention, the top wall of the wiring tray 2 is formed with a receiving groove 2a, and a fiber optic adapter holder 23 is provided in the receiving groove 2a. The fiber optic adapter holder 23 divides the receiving groove 2a into a fiber storage groove 2b and a distribution groove 2c. The side wall of the distribution groove 2c is provided with an inlet 2c1 and an outlet 2c2. The end of the wiring tray 2 near the fiber storage groove 2b extends into the receiving cavity 1a through the opening 1b, and the end of the wiring tray 2 near the distribution groove 2c is located outside the receiving cavity 1a.

[0058] In this embodiment, when the distribution tray 2 is fully extended and suspended, the distribution slot 2c is located outside the opening 1b, facilitating fiber optic distribution operations for the operator. The fiber storage slot 2b, on the other hand, is partially located within the receiving cavity 1a for storing optical fibers. This layout allows the operator to connect and adjust optical fibers directly within the distribution slot 2c without fully removing the distribution tray 2, eliminating the need for frequent removal and insertion of the distribution tray 2 and significantly improving operational efficiency. The fiber optic adapter holder 23 divides the receiving cavity 2a into the fiber storage slot 2b and the distribution slot 2c, enabling categorized management and orderly storage of optical fibers, thus improving the utilization efficiency and operational convenience of the fiber optic distribution box.

[0059] Specifically, the adapter slot has multiple adapter mounting holes connecting the fiber storage tank 2b and the distribution tank 2c. Fiber optic connectors can be plugged into both ends of the adapter. Externally connected optical fibers are plugged into the adapter's end located in the distribution tank 2c via fiber optic connectors. Patch cables in the patch panel 2 are plugged into the adapter's end located in the fiber storage tank 2b via fiber optic connectors. Understandably, both ends of the patch cable are equipped with fiber optic connectors and are respectively plugged into two fiber optic adapters in the fiber storage tank 2b to achieve patching. The fiber storage tank 2b also has a winding reel for winding and combing optical fibers. The distribution tank 2c has an inlet 2c1 and an outlet 2c2 on opposite sides for optical fibers to enter and exit. Distribution operations can be achieved by adjusting the connection relationships between multiple fiber optic connectors and multiple adapters.

[0060] Furthermore, the distribution slot 2c is also equipped with multiple partition ribs, which divide the distribution slot 2c into multiple areas, one part of which is used to install the incoming fiber optic connectors, and another part is used to install the outgoing fiber optic connectors. For example... Figure 11 As shown, the installation area for the incoming fiber optic connector is located in the middle of the distribution slot 2c, while the installation areas for the outgoing fiber optic connector are located on both sides of the distribution slot 2c. Correspondingly, winding reels corresponding to the outgoing fiber optic connections are set on both sides of the fiber storage slot 2b. This design allows the jumpers in the fiber storage slot 2b to be distributed to both sides, avoiding the situation of crowded and messy jumpers in the fiber storage slot 2b. In addition, the connection situations of various devices in application scenarios such as computer rooms and data centers are complex and varied. In this embodiment, the fiber optic adapter card holder 23 for the incoming line is centrally located, which can accommodate both left and right incoming line situations, improving the applicability of the fiber optic distribution box.

[0061] Further, please refer to Figure 7 , Figure 9 and Figure 11In one embodiment of the present invention, a connecting channel 2d is formed on the top wall of the wiring tray 2; a through notch 2d1 is provided on the edge of the wiring tray 2, and the through notch 2d1 penetrates the wiring tray 2 along the direction from the top wall to the bottom wall of the wiring tray 2; the connecting channel 2d connects the fiber storage groove 2b and the through notch 2d1.

[0062] In this embodiment, to increase the capacity of the fiber optic distribution box, multi-layer distribution trays 2 are stacked inside the box body 1 (e.g., Figure 1 (As shown). When multiple wiring trays 2 are stacked, there may be situations where jumpers need to be connected between the upper and lower wiring trays 2. In this embodiment, connecting channels 2d are provided on both sides of the fiber storage tank 2b, and through notches 2d1 are provided on both sides of the wiring tray 2 near the inlet 2c1 and outlet 2c2. This design makes it easy to expose the through notches 2d1 when the wiring tray 2 is pulled out, thereby facilitating jumpers between the upper and lower trays. Specifically, the through notches 2d1 penetrate the wiring tray 2 along the direction from the top wall to the bottom wall of the wiring tray 2, making the upper and lower spaces of the wiring tray 2 connected, and making the connecting channels 2d connect the fiber storage tank 2b and the through notches 2d1. This design allows jumpers in the fiber storage tank 2b to enter the through notches 2d1 from the connecting channels 2d, and then extend through the through notches 2d1 to the fiber storage tank 2b on the next or previous layer of wiring tray 2, realizing jumpers between the upper and lower wiring trays 2. Therefore, in the application scenarios of the multi-layer distribution tray 2, operators can flexibly allocate and connect optical fibers between different layers according to actual needs, without the need for additional patch cord equipment or complex cabling operations. This design not only improves the functionality of the pull-out fiber optic distribution box 100, but also reduces cabling costs and maintenance difficulty, enabling the pull-out fiber optic distribution box 100 to better adapt to the complex and ever-changing needs of fiber optic network deployment.
