Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an optical fiber fusion splicing distribution cabinet. Background Technology

[0002] Fiber optic fusion splicer cabinets are specialized devices for fiber optic splicing and protection. Their main functions are to splice, store, and manage optical fibers, ensuring the quality and stability of fiber optic connections. Fiber optic distribution cabinets, on the other hand, focus on the connection, distribution, and protection of fiber optic lines, and are responsible for the centralized management, patching, and distribution of optical fibers.

[0003] In fiber optic networks, fiber optic fusion splicers typically work in conjunction with fiber optic distribution cabinets. After splicing the input fiber to the pigtails within the splicer, the fusion splicer connects to the distribution cabinet via patch cords. The distribution cabinet then distributes the fiber optic signals to various terminals in an orderly manner through the output fiber. For example, in an FTTH (Fiber to the Home) network, the fusion splicer can be used to splice trunk and branch fibers, while the distribution cabinet distributes the spliced ​​fibers to user terminals.

[0004] However, currently these two types of cabinets are often set up independently. When it is necessary to connect the fiber optic fusion splicer cabinet and the fiber optic distribution cabinet via patch cords, it is usually necessary to use the fiber optic cable trays laid on top of the cabinets. This connection method brings many inconveniences to construction and maintenance. For example, during operation, staff often need to repeatedly move between the two cabinets to confirm whether the output port of the fiber optic fusion splicer cabinet corresponds correctly with the input port of the fiber optic distribution cabinet. This not only leads to low efficiency but also increases the possibility of errors. Utility Model Content

[0042] This utility model proposes a fiber optic fusion splicing distribution cabinet 100.

[0043] Please see Figures 1 to 3 In one embodiment of this utility model, the fiber optic fusion splicing distribution cabinet 100 includes a cabinet body 1, a fusion splicing box 2, a distribution box 4, and cable management posts 3. The cabinet body 1 has a receiving cavity 1a, which includes a fusion splicing cavity 1a1, a connecting cavity 1a2, and a distribution cavity 1a3 connected in sequence. The top wall of the cabinet body 1 is provided with an inlet 1b connected to the fusion splicing cavity 1a1 and an outlet 1c connected to the distribution cavity 1a3. The fusion splicing box 2 is located in the fusion splicing cavity 1a1 and is used to connect the input fiber 21. The distribution box 4 is located in the distribution cavity 1a3 and is used to connect the output fiber 41. The cable management posts 3 are located in the connecting cavity 1a2 and are used to store jumpers 31, which connect the fusion splicing box 2 and the distribution box 4.

[0044] In this embodiment, cabinet 1 is the basic structure of the entire fiber optic fusion splicing and distribution cabinet 100. It contains a receiving cavity 1a, which includes a fusion splicing cavity 1a1, a connecting cavity 1a2, and a distribution cavity 1a3, arranged horizontally and connected sequentially. This cavity design clearly defines the operating areas for fiber optic fusion splicing and distribution, avoiding confusion during operation. The top wall of cabinet 1 has an inlet 1b communicating with the fusion splicing cavity 1a1 and an outlet 1c communicating with the distribution cavity 1a3. This layout allows for convenient access and exit of the input fiber 21 and output fiber 41, while avoiding cluttered cable distribution outside cabinet 1. The input fiber 21 is the fiber externally connected to the fusion splicing and distribution cabinet, such as the fiber in the backbone optical cable of an FTTH network. The output fiber 41 is the fiber exiting the fusion splicing and distribution cabinet, used to connect to downstream user terminals and other network equipment.

[0045] The fusion splice box 2 is located inside the fusion splice cavity 1a1, and its main function is to provide a place for fusion splicing operations for the input optical fiber 21. The fusion splice box 2 has multiple mounting slots for fusion tubes, i.e., multiple fusion tube holders are provided inside the fusion splice box 2. The fusion splice box 2 also has pre-installed pigtails for fusion splicing with the input optical fiber 21. One end of the pigtail, away from the fusion splice point, has an optical fiber connector that plugs into one end of an optical fiber adapter on the outer wall of the fusion splice box 2. The other end of the optical fiber adapter on the outer wall of the fusion splice box 2 is connected to one end of a patch cord 31.

[0046] The distribution box 4 is located inside the distribution cavity 1a3, and its main technical function is to provide a place for connection and distribution of the output optical fiber 41. The distribution box 4 is equipped with an optical fiber adapter for connecting the output optical fiber 41. The other end of the jumper 31 is connected to the optical fiber adapter on the distribution box 4 to realize the optical signal communication between the fusion splice box 2 and the distribution box 4.

[0047] Cable management post 3 is located within the connecting cavity 1a2. Its main technical function is to store jumper cables 31, ensuring their orderly arrangement and management. Please refer to [reference needed]. Figure 3 The cable management post 3 is structurally designed to accommodate the storage capacity and ease of management of the jumper cables 31. Its surface has multiple cable grooves to secure the jumper cables 31 and prevent them from slipping. The cable management post 3 can be cylindrical or semi-cylindrical, and its dimensions are optimized based on the internal space of the cabinet 1; this embodiment does not impose any limitations. The cable management post 3 can be made of engineering plastics or other materials to ensure it is lightweight and has high load-bearing capacity.

[0048] The fusion splice box 2 and the distribution box 4 are connected by jumper cables 31. Jumper cables 31 are pre-terminated optical fibers with pre-installed fiber optic connectors at both ends, which can be connected to the fiber optic adapters on both the fusion splice box 2 and the distribution box 4 to achieve optical signal communication between them. Jumper cables 31 are laid or wound around the cable management posts 3 within the connecting cavity 1a2 to enable fiber optic signal transmission between the fusion splice box 2 and the distribution box 4. This internal connection method avoids the complex operation of laying fiber optic cable trays required in traditional external connection modes, reducing construction and maintenance workload. Specifically, the output port of the fiber optic adapter in the fusion splice box 2 and the input port of the fiber optic adapter in the distribution box 4 are directly connected via jumper cables 31. The jumper cables 31 are arranged orderly within the cable trays under the constraint of the cable management posts 3, ensuring stable transmission of fiber optic signals. Furthermore, a cable management ring 7 is provided below the cable management post 3. The cable management ring 7 is connected to the side wall of the connecting cavity 1a2. The cable management ring 7 is used to restrain the jumper 31 to prevent the jumper 31 from being scattered and to keep the jumper 31 neat and orderly. The back plate 131 of the connecting cavity 1a2 is also provided with a reserved jumper interface 131a. When two fiber optic splice distribution cabinets 100 are installed back to back, the two connecting cavities 1a2 can be connected through the reserved jumper interface 131a of the two, so as to lay the jumper 31.

[0049] This invention optimizes the construction and maintenance process of fiber optic communication networks by integrating fiber optic splicing and cabling functions into a single cabinet 1 and utilizing a connecting cavity 1a2 and cable management posts 3 for internal connection. This integrated design fundamentally changes the traditional working mode, avoiding the need for personnel to repeatedly travel between two cabinets 1 to confirm port correspondences, thus improving the efficiency and convenience of fiber optic splicing and cabling. Simultaneously, the internal connection method reduces fiber optic signal loss and interference during transmission, enhancing the stability and reliability of the fiber optic communication network.

[0050] Further, please refer to Figure 3 In one embodiment of the present invention, the fiber optic fusion splicing distribution cabinet 100 includes multiple fusion splicing boxes 2, multiple distribution boxes 4, and multiple cable management posts 3. The multiple fusion splicing boxes 2 are vertically layered in the fusion splicing cavity 1a1, the multiple distribution boxes 4 are vertically layered in the distribution cavity 1a3, and the multiple cable management posts 3 are vertically layered on the side wall of the connecting cavity 1a2, and each layer includes two horizontally spaced cable management posts 3.

[0051] In this embodiment, to fully utilize the internal space of cabinet 1 and increase the capacity of the fiber optic splicing distribution cabinet 100, the splicing box 2, cable management posts 3, and distribution box 4 are arranged vertically in layers. This allows for the storage of more input optical fibers 21, pigtails, patch cords 31, and output optical fibers 41 within a limited space, thus meeting the needs of large-scale fiber optic communication networks. Simultaneously, the arrangement of two horizontally spaced cable management posts 3 on each layer not only effectively distributes the stress, preventing damage to the cable management posts 3 due to concentrated weight of the patch cords 31, but also provides more balanced support for the patch cords 31, facilitating their orderly arrangement and management and preventing them from slipping due to uneven stress.

[0052] This embodiment, through its multi-layer design, enables the fiber optic fusion splice distribution cabinet 100 to not only meet the needs of large-scale fiber optic communication networks but also improve the efficiency and quality of fiber optic management. The design of the multi-layer fusion splice box 2 and distribution box 4 makes fiber optic splicing and distribution operations more efficient, while the design of two cable management posts 3 on each layer provides better management conditions for the jumper 31. Therefore, the technical solution of this embodiment further improves the space utilization and fiber optic management capabilities of the fiber optic fusion splice distribution cabinet 100.

[0053] Further, please refer to Figure 2 and 3 In one embodiment of this utility model, along the direction from the top wall to the bottom wall of the communication cavity 1a2, the horizontal spacing between the two cable management columns 3 in each layer gradually increases.

[0054] In this embodiment, multiple splice boxes 2 are vertically layered within the splice cavity 1a1, multiple wiring boxes 4 are vertically layered within the wiring cavity 1a3, and multiple cable management posts 3 are vertically layered on the side wall of the connecting cavity 1a2. Each layer includes two horizontally spaced cable management posts 3. To prevent the upper and lower jumper fibers 31 from intertwining, in this embodiment, the horizontal spacing between the two cable management posts 3 in each layer gradually increases along the direction from the top wall to the bottom wall of the connecting cavity 1a2, so that the multi-layer cable management device forms a figure-eight arrangement. In this way, the lower jumper fiber 31 wraps around the upper jumper fiber 31, avoiding the intertwining between the upper and lower jumper fibers 31, which is beneficial for the sorting and distribution of the jumper fibers 31.

[0055] Furthermore, in one embodiment of this utility model, the fiber optic fusion splicing distribution cabinet 100 also includes various identification components, with the same identification components provided on a fusion splicing box 2 and a distribution box 4.

[0056] In this embodiment, please refer to Figure 3 and Figure 10To provide identification, identification areas 5b are provided on the splice box 2 and the distribution box 4. Specifically, the identification areas 5b are located on the fiber optic trays 5 inside the splice box 2 and the distribution box 4. It is important to note that the same type of identification is provided on each splice box 2 and distribution box 4; that is, the identification on the splice box and the distribution box 4 are in a one-to-one relationship. This allows for precise identification of the splice box and distribution box 4 connected to the same bundle of jumpers 31, reducing the time spent by operators searching for cables and improving operational efficiency and convenience. Furthermore, identification can also be provided on the cable management post 3 connected to the bundle of jumpers 31 to further accurately locate the cable management ring 7 connected to the bundle of jumpers 31. Optionally, the identification can use multiple colors as identification features, or it can be identified by text, such as multiple letters or multiple numbers. The identification can be a sticker, a card, or a magnetic tag. This embodiment does not limit this. For example, using... Figure 3 For reference, the top-level fusion splice box 2 is connected to the top-level wiring box 4. At this time, red identification pieces can be set on both the top-level fusion splice box 2 and the top-level wiring box 4 for identification. In addition, the second-level fusion splice box 2 is connected to the second-level wiring box 4. At this time, blue identification pieces can be set on both the second-level fusion splice box 2 and the second-level wiring box 4 for identification.

[0057] Further, please refer to Figure 3 , Figure 10 and Figure 11 In one embodiment of the present invention, the fiber optic fusion splicing distribution cabinet 100 further includes at least two fiber optic trays 5, each fiber optic tray 5 having mounting holes 5a for mounting fusion splice tube holders. At least one fiber optic tray 5 is slidably disposed in the fusion splicing box 2, and at least one fiber optic tray 5 is slidably disposed in the distribution box 4.

[0058] In this embodiment, considering that traditional welding trays and wiring trays are not interchangeable, different trays need to be designed and manufactured separately, which not only increases production costs but also extends the production cycle. However, the universal tray design adopted in this embodiment only requires one set of molds to produce trays suitable for both welding box 2 and wiring box 4, significantly reducing mold costs. The universal tray design simplifies the production process, reduces the types of parts and management complexity involved in production. Production personnel can focus on producing one type of tray, thereby improving production efficiency and product quality.

[0059] Specifically, the fiber optic tray 5 adopts a universal design, featuring mounting holes 5a for attaching fusion splice tube holders 51. When used as a splicing tray, the fusion splice tube holders 51 are machined, attached to the mounting holes 5a, and placed inside the splicing box 2. When used as a wiring tray, the fusion splice tube holders 51 are removed, and the tray is placed inside the wiring box 4. This universal design allows the same tray to be used in both splicing boxes 2 and wiring boxes 4, greatly improving the flexibility and ease of operation of the equipment, and making operation convenient and quick.

[0060] In addition, the sliding design of the fiber optic tray 5 makes the installation and removal of the tray more convenient. Operators can easily push the tray into or pull it out of the box, further improving work efficiency.

[0061] Further, please refer to Figures 3 to 5 In one embodiment of this utility model, the cabinet 1 is further provided with an inlet channel 1d and an outlet channel 1f. The inlet channel 1d is located on the side of the welding cavity 1a1 facing away from the wiring cavity 1a3 and connects the inlet port 1b with the welding cavity 1a1. The outlet channel 1f is located on the side of the wiring cavity 1a3 facing away from the welding cavity 1a1 and connects the outlet port 1c with the wiring cavity 1a3. The inlet channel 1d and the outlet channel 1f are respectively provided with cable management plates 11. The cable management plates 11 are provided with a plurality of first binding avoidance holes 11a. The inner sidewall of the first binding avoidance holes 11a is provided with a first T-shaped protrusion 111.

[0062] In this embodiment, the fiber optic fusion splicing distribution cabinet 100 also has an inlet channel 1d and an outlet channel 1f within its cabinet body 1. The inlet channel 1d is located on the side of the fusion splicing cavity 1a1 facing away from the distribution cavity 1a3 and connects the inlet port 1b to the fusion splicing cavity 1a1. The outlet channel 1f is located on the side of the distribution cavity 1a3 facing away from the fusion splicing cavity 1a1 and connects the outlet port 1c to the distribution cavity 1a3. Both the inlet channel 1d and the outlet channel 1f extend along the direction from the top wall to the bottom wall of the receiving cavity 1a, so as to adapt to the multilayer fusion splicing box 2 and the multilayer distribution box 4, respectively. This layout allows the input fiber 21 and the output fiber 41 to be centrally managed and organized through the inlet channel 1d and the outlet channel 1f, respectively, avoiding the messy distribution of fibers within the cabinet body 1. The layout of the inlet channel 1d and the outlet channel 1f allows the input fiber 21 and the output fiber 41 to be centrally managed and organized through these channels, respectively. Specifically, an inlet channel 1d is set up to collect and organize the input optical fibers 21 that enter from the inlet port 1b and then distribute them to the fusion splice boxes 2 of each layer, so that the input optical fibers 21 are neat and orderly and avoid messiness; similarly, the input optical fibers 21 that are dispersed in each layer are collected and organized and then connected out from the outlet port 1c, so that the output optical fibers 41 are neat and orderly and avoid messiness.

[0063] Furthermore, cable management plates 11 are respectively provided in the inlet channel 1d and the outlet channel 1f. Each cable management plate 11 has multiple first binding avoidance holes 11a, and the inner wall of each first binding avoidance hole 11a has a first T-shaped protrusion 111. By providing binding avoidance holes and the first T-shaped protrusion 111, cable ties can be used to constrain the optical fibers, further ensuring their neat and orderly arrangement. Specifically, the first binding avoidance holes 11a allow the cable ties to be directly inserted laterally into one side of the first T-shaped protrusion 111 without needing to be threaded through, improving binding efficiency. The first T-shaped protrusion 111 provides a limit for the cable ties, preventing them from loosening.

[0064] In summary, this embodiment, by setting up an inlet channel 1d and an outlet channel 1f, allows the input optical fiber 21 and the output optical fiber 41 to be centrally managed and organized through these channels. Simultaneously, by setting up a cable management plate 11 with binding holes and a first T-shaped protrusion 111, the optical fibers can be constrained using cable ties, enabling the cable management plate 11 to better constrain the optical fibers.

[0065] Further, please refer to Figure 3 and Figure 6 In one embodiment of the present invention, the fiber optic splicing distribution cabinet 100 further includes two optical cable fixing plates 6. Both optical cable fixing plates 6 are provided on the outer top wall of the cabinet body 1. One optical cable fixing plate 6 is provided corresponding to the inlet port 1b, and the other optical cable fixing plate 6 is provided corresponding to the outlet port 1c. The optical cable fixing plate 6 is provided with a plurality of second binding avoidance holes 6a, and the inner side wall of the second binding avoidance hole 6a is provided with a second T-shaped protrusion 61.

[0066] In this embodiment, two optical cable fixing plates 6 are installed on the outer top wall of the cabinet 1, respectively located on one side of the inlet 1b and the other side of the outlet 1c. The optical cable fixing plates 6 are used to effectively fix and manage the optical cable when it enters and leaves the cabinet 1, preventing it from loosening or being damaged by external forces. Specifically, the optical cable fixing plates 6 are provided with multiple second binding avoidance holes 6a, which are used to secure the optical cable with cable ties. The inner sidewall of the second binding avoidance holes 6a is provided with a second T-shaped protrusion 61, which allows the cable tie to be securely fastened to, preventing it from loosening or slipping during use. By setting up the optical cable fixing plates 6 and designing the second binding avoidance holes 6a and the second T-shaped protrusion 61 on the fixing plates, the optical cable can be effectively fixed when entering and leaving the cabinet 1, preventing it from loosening due to external forces, which could lead to fiber optic damage from traction, and also preventing the optical cable from becoming messy and disorderly, thus facilitating maintenance. In addition, the optical cable fixing plate 6 is located on the top of the cabinet 1, saving installation space inside the cabinet.

[0067] Further, please refer to Figure 2 and Figure 7In one embodiment of the present invention, the cabinet 1 includes a mounting bracket 12 and a plurality of panels 13. The mounting bracket 12 is configured as a frame structure, and the plurality of panels 13 are detachably arranged around the periphery of the mounting bracket 12 to form a receiving cavity 1a.

[0068] In this embodiment, the detachability of panel 13 not only facilitates rapid assembly during production but also allows for partial adjustments or replacements of cabinet 1 as needed during actual use. For example, if a panel 13 is damaged, it can be replaced directly without replacing the entire cabinet 1, thereby reducing maintenance costs. Furthermore, this design allows for the removal of some panels 13 in certain situations without affecting the basic functionality of cabinet 1, further enhancing the flexibility and applicability of the equipment.

[0069] The mounting bracket 12 has a frame structure, providing stable support for the cabinet 1. Multiple panels 13 are detachably mounted on the periphery of the mounting bracket 12, forming a complete receiving cavity 1a. This design not only facilitates assembly and maintenance but also allows for flexible adjustment of the cabinet 1's structure when needed. For example, in some applications, the complete cabinet 1 structure may not be required; in this case, some panels 13 can be removed without affecting the basic functionality of the cabinet 1, thus reducing costs.

[0070] Specifically, panel 13 includes a back panel 131, side panels 132, door panels 133, bottom panel 134, and top panel 135, each with its specific function. The back panel 131 and side panels 132 primarily support and protect the equipment inside the cabinet 1. The door panel 133 can rotate or slide relative to the mounting bracket 12 to expose the components inside the receiving cavity 1a, facilitating operation and maintenance by personnel. The bottom panel 134 and top panel 135 provide stable support and protection for the cabinet 1. This modular design allows for the selection of different panel 13 combinations according to actual needs, thus enabling customization of the cabinet 1.

[0071] Further, please refer to Figures 7 to 9 In one embodiment of the present invention, the mounting bracket 12 includes multiple crossbeams 121, multiple columns, and multiple connectors 123. Two crossbeam mounting grooves 123a and one column mounting groove 123b are formed on the connectors 123. The crossbeam mounting grooves 123a are used to limit the crossbeams 121, and the column mounting grooves 123b are used to limit the columns 122.

[0072] In this embodiment, the mounting bracket 12 includes at least eight crossbeams 121, two uprights 122, and four connectors 123. Two crossbeam mounting slots 123a and one upright mounting slot 123b are formed on each connector 123. The crossbeam mounting slots 123a are used to limit the crossbeams 121, and the upright mounting slots 123b are used to limit the uprights 122. Thus, the connectors 123 enclose the crossbeams 121 and uprights 122, forming a stable frame structure. Furthermore, the design of the crossbeam mounting slots 123a and upright mounting slots 123b allows the crossbeams 121 and uprights 122 to be precisely installed, ensuring the structural stability of the entire mounting bracket 12. In this way, the mounting bracket 12 can better withstand the weight of the equipment inside the cabinet 1 and external mechanical stress, thereby improving the load-bearing capacity of the cabinet 1 and extending its service life.

[0073] Further, please refer to Figure 8 and Figure 9 In one embodiment of the present invention, a recessed groove 122a is formed on each of the adjacent side walls of the column, and the recessed groove 122a is used for the panel 13 to extend into and be fixed.

[0074] In this embodiment, the column 122 adopts a seven-fold profile design, which significantly increases the contact and fixing surface between the panel 13 and the column 122 compared to the traditional square tube profile. Specifically, an offset groove 122a is formed on each of the adjacent side walls of the column 122. This design allows the edge of the panel 13 to be embedded inside the column 122. The size and shape of the offset groove 122a are adapted to the panel 13, thereby achieving a firm connection between the panel 13 and the column 122. After the edge of the panel 13 is embedded in the offset groove 122a, the inner wall of the offset groove 122a can prevent the panel 13 from sliding relative to the column 122, thereby enhancing the connection strength between the column 122 and the panel 13. Furthermore, this offset design relatively reduces the outer contour volume of the cabinet 1, that is, reduces the space occupied by the cabinet 1, making it easier for the cabinet 1 to be used in scenarios with limited installation space.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
