[0027] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following combination Figure 1-Figure 3 The present invention describes a modular optical fiber distribution box.

[0029] like Figures 1 to 3 As shown, the present invention provides a modular fiber optic distribution box, comprising: a main body 1 and a panel 2. The main body 1 has a mounting cavity 11 therein, and a mounting opening 12 on one side of the main body 1 that connects the mounting cavity 11 to the outside. The main body 1 is provided with a first clamping portion 13. The panel 2 is mounted in the mounting opening 12; the panel 2 is provided with a plurality of mounting holes 21, each of which is used to install a connection port for an optical fiber. The panel 2 is provided with a second clamping portion 22 that adapts to the first clamping portion 13 and is clamped to the first clamping portion 13.

[0030] In this embodiment, a mounting cavity 11 is provided in the main body 1, and the mounting cavity 11 is used to accommodate optical fibers. It is understood that the mounting cavity 11 can accommodate multiple optical fibers. A mounting port 12 is provided on one side of the main body 1 to connect the mounting cavity 11 with the outside. The mounting port 12 is used to install the panel 2. The panel 2 is provided with multiple mounting holes 21 to install the connection ports of multiple optical fibers. The multiple optical fibers in the mounting cavity 11 can be connected to the corresponding connection ports, and the wide connection port can be used to connect to an external wiring harness. At the same time, a first clamping portion 13 and a second clamping portion 22 are provided on the main body 1 and the panel 2, respectively. The first clamping portion 13 and the second clamping portion 22 are clamped to each other, so that the main body 1 and the panel 2 can be quickly disassembled and assembled, and the panel 2 can be easily replaced.

[0031] It is understandable that there can be multiple panels 2, and different numbers of mounting holes 21 are set on multiple panels 2. Users can quickly replace panels 2 according to the demand for the number of ports. It is easy to use and there is no need to replace the entire modular fiber optic distribution box.

[0032] The modular fiber optic distribution box of the present invention is configured to accommodate any number of optical fibers by providing an installation cavity 11 in a main body 1, and installing a panel 2 at a mounting opening 12 of the installation cavity 11. The panel 2 is provided with installation holes 21 for installing connection ports so that the optical fibers can be connected to an external wiring harness through corresponding connection ports. At the same time, the panel 2 and the main body 1 are fixed by a first clamping portion 13 and a second clamping portion 22, which is convenient for assembly and disassembly, allowing the user to quickly replace the panel 2 as needed, effectively solving the problem in the prior art that the number of ports on the fiber optic panel on the distribution box is fixed, and when the user's demand for the number of ports changes, the entire distribution box needs to be replaced, which is inconvenient to use and replace.

[0033] Specifically, in some embodiments, Figure 1 and Figure 2 As shown, the first engaging portion 13 is a engaging hole, which is a through hole. The second engaging portion 22 includes a connecting portion 221 and a pressing portion 222. The connecting portion 221 is provided on the side of the panel 2 facing the installation cavity 11, and the pressing portion 222 is provided on the connecting portion 221. The pressing portion 222 is inserted into the engaging hole.

[0034] In this embodiment, by setting the first clamping portion 13 as a clamping hole, the second clamping portion 22 includes a connecting portion 221 and a pressing portion 222, the connecting portion 221 is a transition connection structure between the pressing portion 222 and the panel 2, and the pressing portion 222 is inserted into the clamping hole, so that the first clamping portion 13 and the second clamping portion 22 are clamped to each other.

[0035] At the same time, by setting the snap-fitting hole as a through hole, the snap-fitting hole can connect the installation cavity 11 and the outside, making it more convenient for the user to disassemble and assemble the panel 2 and the main body 1. Specifically, when installing the panel 2 on the main body 1, the side of the panel 2 provided with the second snap-fitting portion 22 can be directed toward the installation opening 12, and the panel 2 can be pushed into the installation cavity 11. During the pushing process, the user presses the pressing portion 222, causing the connecting portion 221 to slightly deform inward, allowing the second snap-fitting portion 22 to enter the installation cavity 11. The user continues to push the panel 2 until the pressing portion 222 reaches the snap-fitting hole. After the pressing portion 222 reaches the position of the snap-fitting hole, the connecting portion 221 rebounds, causing the pressing portion 222 to be inserted into the snap-fitting hole. The first snap-fitting portion 13 and the second snap-fitting portion 22 are snap-fitted and fixed, completing the installation. When the panel 2 needs to be removed from the main body 1, the pressing portion 222 can be pressed from the outside of the main body 1 through the snap-fit ​​hole to disengage the pressing portion 222 from the snap-fit ​​hole, and the pressing portion 222 can be pushed toward the outside of the mounting opening 12 to release the first snap-fit ​​portion 13 and the second snap-fit ​​portion 22 from being engaged, so that the panel 2 can be removed from the mounting opening 12 and replaced. The structure is simple and the operation is convenient.

[0036] In some embodiments, as Figure 1 and Figure 2 As shown, there are two clamping holes, which are respectively located on the side walls on opposite sides of the installation opening 12. The second clamping portions 22 and the clamping holes are arranged in a one-to-one correspondence.

[0037] In this embodiment, by providing two engaging holes on the side walls on opposite sides of the mounting opening 12 and providing second engaging portions 22 on the panel 2 corresponding one to the engaging holes, the two second engaging portions 22 of the panel 2 can be engaged with the engaging holes on both sides, thereby achieving a more balanced force on both ends of the panel 2 and a more stable engagement. The two engaging holes and the second engaging portions 22 also facilitate user operation.

[0038] Optionally, in some embodiments, there may be more than two snap-fit ​​holes, and the second snap-fit ​​portion 22 and the plurality of snap-fit ​​holes are provided in a one-to-one correspondence to enhance the connection strength between the panel 2 and the main body 1 .

[0039] In a specific embodiment, Figure 2 As shown, the connecting portion 221 includes a first part and a second part that are connected. The first part is arranged on the side of the panel 2 facing the installation cavity 11, and the second part is arranged on the first part and extends from the first part to the side of the installation cavity 11 having a snap-on hole. The pressing portion 222 is arranged at an end of the second part away from the first part.

[0040] In some embodiments, as Figure 1As shown, a winding post 111 and a wire groove 112 are provided in the mounting cavity 11. The winding post 111 is used to coil the optical fiber, and both ends of the wire groove 112 have openings, one of which faces the winding post 111 and the other faces the mounting hole 21.

[0041] In this embodiment, a winding post 111 is provided in the installation cavity 11 so that the optical fiber contained in the installation cavity 11 can be wound around the winding post 111, thereby preventing the optical fiber from being arranged in a disorderly manner in the installation cavity 11, causing the optical fibers to be entangled with each other and making it inconvenient to route the cables. At the same time, a wire groove 112 with openings at both ends is provided between the winding post 111 and the panel 2, so that the optical fiber on the winding post 111 can enter the wire groove 112 through the opening at one end of the wire groove 112 and be guided to the same-direction installation hole 21 through the wire groove 112, so that the wire bundles of different optical fibers near the connection port can be isolated and separated from each other, so that the user can route and organize the cables, with a simple structure and convenient use.

[0042] It is understandable that the number of the wire grooves 112 can be set according to the number of the mounting holes 21 , and the opening at one end of the wire groove 112 can face the corresponding mounting hole 21 .

[0043] In one embodiment, the mounting cavity 11 is provided with paired partitions, each pair of partitions being arranged opposite to each other, and forming a wire groove 112 between each pair of partitions. Multiple pairs of partitions are arranged side by side at intervals, forming a plurality of wire grooves 112 arranged in parallel.

[0044] In this embodiment, if Figure 1 As shown, the winding post 111 is arranged on the side wall of the installation cavity 11 , and a first limiting plate 113 is arranged on the outer peripheral wall of the winding post 111 and is arranged opposite to the side wall.

[0045] In this embodiment, by arranging the winding post 111 on the side wall of the installation cavity 11 and arranging a first limiting plate 113 on the outer peripheral wall of the winding post 111, a first clamping space for clamping the optical fiber can be formed between the first limiting plate 113 and the side wall. The optical fiber is coiled on the winding post 111 and is located in the first clamping space, which can prevent the optical fiber from axially detaching from the winding post 111, making the position of the optical fiber more stable and not easy to be entangled with each other and arranged in a disorderly manner.

[0046] In some specific embodiments, Figure 1 As shown, there are multiple first limiting plates 113 , and the multiple first limiting plates 113 are arranged at intervals along the circumference of the winding rod 111 .

[0047] In some embodiments, as Figure 1 As shown, a wiring board 114 is further provided in the installation cavity 11 , and the wiring board 114 and the outer peripheral wall of the winding post 111 are arranged opposite to each other.

[0048] In this embodiment, by setting a distribution plate 114 opposite to the outer peripheral wall of the winding pole 111, a part of the optical fiber wound on the winding pole 111 can pass through one side of the distribution plate 114, and another part of the optical fiber can pass through the other side of the distribution plate 114, thereby preliminarily dividing the multiple optical fibers to avoid the multiple optical fibers from being entangled with each other.

[0049] In some specific embodiments, such as Figure 1 As shown, there are two branching plates 114, which are respectively located on both sides of the winding post 111 so as to respectively branch the wires on both sides of the winding post 111. Furthermore, multiple branching plates 114 can be provided as required, which is not limited in this application.

[0050] Optionally, in some embodiments not shown, there are multiple breakout plates 114, which are spaced apart along the radial direction of the winding post 111. Specifically, a portion of the optical fibers can pass between the breakout plate 114 closest to the winding post 111 and the winding post 111; a portion of the optical fibers can pass between two breakout plates 114; and a portion of the optical fibers can pass from the side of the breakout plate 114 closest to the winding post 111 away from the other breakout plates 114, thereby separating the optical fibers into multiple paths and better preventing entanglement.

[0051] Specifically, in some embodiments, Figure 1 As shown, the branching plate 114 is arc-shaped, and the concave side of the branching plate 114 faces the winding post 111 .

[0052] In this embodiment, by setting the distribution plate 114 to be arc-shaped, since the optical fiber wound on the winding pole 111 is spiral-shaped, the arc-shaped distribution plate 114 can better adapt to the shape of the wound optical fiber, has a simple structure, and is convenient for optical fiber distribution.

[0053] In some embodiments, as Figure 1 As shown, the line dividing plate 114 is arranged on the side wall of the installation cavity 11 , and second limiting plates 115 are arranged on both sides of the line dividing plate 114 and are arranged opposite to the side wall.

[0054] In this embodiment, by arranging the distribution plate 114 on the side wall of the installation cavity 11, and arranging second limiting plates 115 on both sides of the distribution plate 114, a second clamping space for clamping the optical fiber can be formed between the second limiting plate 115 and the side wall. The optical fibers on both sides of the distribution plate 114 are respectively located in the two second clamping spaces on both sides of the distribution plate 114, which can prevent the optical fibers from escaping from the range of the distribution plate 114 in a direction perpendicular to the side wall, causing the two parts of the optical fibers to be mixed together again, making the position of the optical fibers more stable and not easy to be entangled with each other and arranged in a disorderly manner.

[0055] In some embodiments, as Figure 1 and Figure 3 As shown, the main body 1 includes a box body 14 and a box cover 15. The box cover 15 is detachably mounted on the box body 14 and engages with the box body 14 to form a mounting cavity 11.

[0056] In this embodiment, the main body 1 is divided into a box body 14 and a box cover 15, and the box body 14 and the box cover 15 are connected to form an installation cavity 11 to accommodate the optical fiber. When the user needs to install the optical fiber into the installation cavity 11 or to inspect, maintain or replace the optical fiber inside the installation cavity 11, the box cover 15 can be removed from the box body 14. The structure is simple and easy to operate.

[0057] Specifically, in some embodiments, Figure 1 and Figure 3 As shown, the box body 14 is provided with a third clamping portion 141 , and the box cover 15 is provided with a fourth clamping portion 151 at a position corresponding to the third clamping portion 141 , and the third clamping portion 141 is clamped with the corresponding fourth clamping portion 151 .

[0058] In this embodiment, by providing a third clamping portion 141 and a fourth clamping portion 151 on the box body 14 and the box cover 15 respectively, the third clamping portion 141 and the fourth clamping portion 151 are clamped to each other to fix the box cover 15 and the box body 14, so that the box body 14 and the box cover 15 can be quickly disassembled and assembled.

[0059] Specifically, in some embodiments, a mounting opening 12 is formed on one side of the box body 14, and a cover opening is formed on the other side. The cover opening is used to install the box cover 15, and a plurality of third clamping portions 141 are arranged at intervals on the edge of the cover opening. The fourth clamping portion 151 and the third clamping portion 141 are arranged in a one-to-one correspondence.

[0060] Furthermore, the fourth clamping portion 151 is a hook, and the third clamping portion 141 is a stop structure adapted to the hook. The inner side of the hook overlaps with the corresponding stop mechanism, thereby achieving the clamping of the third clamping portion 141 and the fourth clamping portion 151.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
