Description

Technical Field

[0001] This utility model relates to the field of communication junction box technology, and in particular to a multifunctional high-density fiber optic junction box. Background Technology

[0002] Currently, conventional patch panel boxes on the market only have a single function. Each time a function is used, a corresponding box is required, which takes up a lot of space and is expensive. In addition, the patch panel products on the market use screws or clips to fix the upper and lower cover structures, which makes disassembly, replacement and maintenance very inconvenient. Disassembling the cover wastes a lot of time and is easy to hurt hands. Due to the size limitation, conventional patch panels can only accommodate 96 optical fibers on a standard 1U chassis, which is too low a density of optical fibers.

[0003] Therefore, this application requires the design of a multifunctional fiber optic high-density distribution box to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional high-density fiber optic distribution box. This distribution box integrates a splitter, fusion splice, and MPO pre-connection into one unit, allowing users to freely choose the functions they need. It has advantages such as small footprint, reduced cost, and convenient installation, disassembly, and maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The middle position of the junction box body is provided with a fusion splice tray and a splitter slot, and the fusion splice tray and the junction box body are detachable; the rear part of the junction box body is provided with an MPO adapter and a fiber optic cable entry and exit fixing component; the MPO adapter and the fiber optic cable entry and exit fixing component are movably connected to the junction box body.

[0008] By adopting the above technical solution, this patch panel integrates fiber optic fusion splicing, MPO pre-connection, and PLC optical splitter functions, eliminating the need for customers to purchase three different module boxes for multi-functional use. A single high-density module box can be used for various functional layouts. It occupies little space, has a high utilization rate, and features a push-to-unlock mechanism with a top and bottom cover structure, saving significant time. This high-density patch panel can accommodate 144 fiber optic cores in a standard 1U chassis, allowing for even greater fiber density. The fusion splice tray and the patch panel body are detachable, allowing for quick removal when using other functions. The MPO adapter and fiber optic cable entry / exit fixing components are all movably connected to the patch panel body, facilitating installation, disassembly, and other processes.

[0009] Preferably, there are two fusion splice trays, and the splitter slot is disposed between the two fusion splice trays; there are multiple MPO adapters, and multiple fiber optic cable entry and exit fixing components.

[0010] By adopting the above technical solution, the splitter, fusion splice, and MPO pre-connection are integrated into one unit, allowing users to freely choose the required functions and reducing costs. The ultra-thin design minimizes space occupation, and this high-density patch panel can accommodate 144 fiber optic cables in a standard 1U chassis. In practical applications, there are three or more MPO adapters and fiber optic cable entry / exit fixing components, which can be freely combined according to actual usage requirements to meet user needs.

[0011] Preferably, the junction box body is provided with a mounting groove for mounting a fusion splice tray, the mounting groove is provided with a positioning post, the positioning post is engaged with the mounting hole on the fusion splice tray, and the top of the positioning post is provided with a first locking block, which can engage with the protrusion at the mounting hole.

[0012] By adopting the above technical solution, the first locking block on the positioning post is engaged with the boss at the mounting hole, making it convenient to install and disassemble the welding plate and the wiring box.

[0013] Preferably, the tail portion of the junction box body is provided with a first slot and a second slot for installing the MPO adapter and the fiber optic cable entry and exit fixing component, respectively. The first slot is provided with a first positioning block, and the first positioning block is provided with a vertically arranged first positioning groove; the second slot is provided with a second positioning block, and the second positioning block is provided with a vertically arranged second positioning groove.

[0014] By adopting the above technical solution: the MPO adapter is installed in the first slot, and the fiber optic cable entry and exit fixing component is installed in the second slot; during actual installation, the first positioning slot on the first positioning block is inserted into the strip block on the MPO adapter, and the second positioning slot on the second positioning block is inserted into the strip block on the fiber optic cable entry and exit fixing component, making it easy to install, disassemble, and maintain.

[0015] Preferably, the rear of the wiring box body is provided with two first slots, which are located on the outside of the two first slot openings; the rear of the top cover is provided with two second blocks, which are arranged vertically and vertically corresponding to and engaged with the two first slots.

[0016] By adopting the above technical solution: two second clips are used to engage with two first clip slots, which can prevent the tail of the top cover from bulging when the top cover is installed with the wiring box body.

[0017] Preferably, the wiring box body has an upwardly bent protrusion on the side near the second slot at the rear, and the protrusion has an inclined lower protrusion, which is integrally formed with the protrusion.

[0018] Preferably, a pressure plate is provided on the upper cover near the tail end, and a pressure block is provided on the inner tail of the pressure plate, which abuts against the tail of the convex plate; an inclined upper protrusion is provided on the inner front of the pressure plate, and the upper protrusion and the lower protrusion are arranged vertically and vertically, and the vertical surface of the upper protrusion is engaged with the vertical surface of the lower protrusion on the convex plate.

[0019] Preferably, the junction box body is provided with sliders on both sides, and the top cover is provided with grooves on both sides, and the sliders can slide along the grooves.

[0020] By adopting the above technical solution: when the top cover is installed with the junction box body, the vertical surfaces of the upper protrusion and the lower protrusion on the pressure plate interlock. When it is necessary to open the top cover, it can be unlocked by pressing down on the arrow end of the pressure plate for about 1 second. This causes the pressure block on the inner side of the pressure plate to press down on the protrusion, thereby causing the lower protrusion at the front end of the protrusion to slide off from the upper protrusion on the inner side of the pressure plate. Then, the top cover is pulled open towards the rear. At the same time, the two second locking blocks at the rear disengage from the two first locking slots, and the sliders on both sides slide along the slide grooves, thus enabling the disassembly of the top cover from the junction box body. Conversely, when the top cover is pushed forward, the vertical surfaces of the upper protrusion and the lower protrusion on the protrusion plate interlock, and the second locking blocks engage with the first locking slots. The sliders on both sides slide along the slide grooves, thus enabling the quick installation of the top cover from the junction box body. The design incorporates sliders and grooves on both sides, which position and lock the top cover to the junction box body during installation. The top cover uses a press-to-unlock mechanism, allowing for one-second unlocking and removal without the need for tools, making cable replacement flexible and saving several times the time.

[0021] Preferably, the front end of the junction box body is provided with multiple support plates, which are spaced apart and integrally formed with the junction box body; the front end of the top cover is provided with multiple second slots, which can engage with the multiple support plates.

[0022] By adopting the above technical solution: multiple support plates are used to support the top cover, so that when the top cover is installed with the wiring box body, multiple second slots engage with multiple support plates, thereby making the top cover stable and reliable.

[0023] Preferably, the junction box is an 8-core module box, a 12-core module box, a 16-core module box, or a 24-core module box.

[0024] By adopting the above technical solution: the patch panel here can be any one of an 8-core, 12-core, 16-core, or 24-core module box, and any one of the 8-core, 12-core, 16-core, or 24-core module boxes can be a patch panel that integrates fiber optic fusion splicing, MPO pre-connection, and PLC optical splitter functions; the specific number and installation location can be determined according to the actual situation to meet the actual usage requirements.

[0025] This utility model has the following beneficial effects:

[0026] This utility model integrates fiber optic fusion splicing, MPO pre-connection, and PLC optical splitter functions into one unit, saving customers the need to purchase three different module boxes for multi-functional use. Multiple functional layouts can be implemented using a single high-density module box. It occupies little space, maximizes utilization, and features a top-and-bottom cover structure with a press-to-unlock mechanism that takes only one second, saving significant time.

[0027] This utility model uses sliding grooves on both sides for locking, and the top cover is unlocked by pressing. It can be unlocked and removed in 1 second without the need for tools. It is flexible for changing wires and saves several times the time.
