Description

Technical Field

[0001] This utility model belongs to the field of optical communication equipment technology, and in particular relates to a cable storage type optical cable splitter box. Background Technology

[0002] With the acceleration of global informatization and the in-depth advancement of network construction such as "fiber to the home" and "fiber to the home," optical communication networks have become the infrastructure of modern information society. During the laying of optical fiber links, optical fiber splitters, as an indispensable passive optical device, are widely used at the connection points between trunk optical cables and distribution optical cables. They provide a safe and reliable physical protection and management environment for optical fiber splicing, splitting, storage, and distribution, and are key interface devices for ensuring stable optical signal transmission.

[0003] However, conventional fiber optic splitter boxes in existing technologies have revealed many shortcomings in engineering practice. During installation, a length of fiber optic cable is usually reserved to accommodate future line adjustments, fault repairs, or network expansions. Most traditional splitter boxes lack sufficient space to accommodate this reserved cable, forcing installers to coil it externally. This "external cable coiling" exposes the cable directly to the environment, making it highly susceptible to damage from vehicle scratches, animal bites, vandalism, or severe weather, directly threatening the safety of communication lines. Furthermore, the haphazard external cable coils not only severely impact the aesthetics of the city and community environment but also greatly inconvenience daily inspections and maintenance, making it difficult to quickly traverse the lines during fault diagnosis and reducing operational efficiency.

[0004] Therefore, existing technologies have significant technical shortcomings in handling reserved optical cables. The key challenge lies in how to provide effective physical protection while simultaneously managing reserved optical cables flexibly and efficiently. Specifically, the industry needs a new solution that not only avoids security, reliability, and aesthetic issues caused by exposed reserved optical cables, but also flexibly adapts to the varying storage capacity requirements of optical cables during the initial stages of network construction and future expansion. This would reduce total lifecycle costs while simplifying installation and maintenance complexity. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a cable storage type optical cable splitter box.

[0006] A cable storage type optical cable splitter box, comprising:

[0007] The housing is divided into a wiring layer and a cable storage layer.

[0008] The wiring layer is used for splicing, splitting and wiring operations of optical cables;

[0009] The cable storage layer is used to store the reserved optical cable that will enter the box;

[0010] The cable storage layer and the wiring layer are provided with a connecting channel for the optical fiber core to pass through. The cable storage layer is provided with a cable storage assembly, which is used to adjust and limit the winding path and storage space of the optical cable according to the reserved length of the optical cable.

[0011] Furthermore, the cable storage assembly includes at least one adjustable cable storage baffle, which has multiple selectable installation positions on the bottom plate of the cable storage layer, and can be adjusted to reserve storage space defined by the optical cable by changing its installation position.

[0012] Furthermore, the wiring layer is fixedly provided with a fusion splice tray for carrying the optical fiber splice tube and an adapter assembly for installing the optical fiber adapter.

[0013] Furthermore, the wiring layer is also provided with at least one winding post, which is used to store the pigtails connected to the adapter assembly or to perform fiber optic patching.

[0014] Furthermore, the housing of the wiring layer and the housing of the cable storage layer are two independent structures, with the housing of the cable storage layer located below the housing of the wiring layer.

[0015] Furthermore, the housing of the wiring layer is pivotally connected to the housing of the cable storage layer on one side by a hinge, and the other side is detachably connected by a fastener, so that the cable storage layer can be flipped open relative to the wiring layer.

[0016] Furthermore, the cable storage layer has cable inlet and outlet ports on its box wall, and cable inlet and outlet protective coils are installed at the cable inlet and outlet ports; the cable storage layer is also provided with fixing posts for fixing the optical cable reinforcing core.

[0017] Furthermore, a cable tie is provided inside the wiring layer near the connecting channel for bundling and fixing the optical cable entering the wiring layer.

[0018] Furthermore, a protective coil is provided at the connecting channel to protect the optical fiber core from damage when passing through the channel.

[0019] Furthermore, the housing also includes an openable door assembly, which is pivotally connected to the housing of the wiring layer for sealing the internal space of the wiring layer.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides a cable-storage type optical fiber splitter box. By designing the box body to include an independent cable storage layer and a distribution layer, and setting an adjustable cable storage component within the cable storage layer, it fundamentally solves a series of safety, management, and aesthetic problems caused by the need to coil the reserved optical cable on the outside of the traditional fiber splitter box. This design structure completely houses the reserved optical cable inside the enclosed cable storage layer, protecting it from external environmental corrosion and physical damage, enhancing the protection level of the optical cable and the operational stability of the communication system, while also making the installation site neat and aesthetically pleasing. On the other hand, the spatial adjustability of the cable storage component allows the cable storage capacity to flexibly match the different needs of network construction in the early stages and later expansion. When additional optical cables are needed, upgrades can be completed without replacing the entire box, significantly improving application flexibility and adaptability to future development, while reducing construction difficulty and total life-cycle construction costs.

The singular forms "a" and "the" as used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and not intended to limit it.

[0030] Please see Figure 1 and Figure 2 This embodiment provides a cable storage type optical cable splitter box 1000. The splitter box includes a box body 1100, which is structurally divided into upper and lower functional areas, namely the upper wiring layer 1110 and the lower cable storage layer 1120.

[0031] The distribution layer 1110 is the main area for fiber optic operations. Its internal space is used to house various components required for fiber optic splicing, splitting, and distribution. Engineers complete the connection work between the backbone optical cable and the distribution optical cable cores here. The cable storage layer 1120 is a dedicated storage space used to store complete sections of optical cable that are introduced from the outside into the housing 1100 for future maintenance or expansion.

[0032] To achieve fiber optic connectivity between the two layers, at least one connecting channel 1130 is provided between the cable storage layer 1120 and the wiring layer 1110. After the reserved optical cable is coiled and fixed in the cable storage layer 1120, the fiber core is stripped out and passed upward into the wiring layer 1110 through this connecting channel 1130 for subsequent fusion splicing and wiring.

[0033] Specifically, a cable storage assembly 1121 is installed inside the cable storage layer 1120. This cable storage assembly 1121 is not a simple fixed structure. Its design purpose is to flexibly and adjustably plan a reasonable winding path and a suitable storage space for the optical cable according to the actual length and diameter of the reserved optical cable introduced. This allows the same fiber distribution box to meet the compact storage of a small number of optical cables in the early stage, and to adapt to the expansion needs of a large number of optical cables in the later stage.

[0034] In a specific embodiment, see detailed description. Figure 2 In this embodiment, the cable storage assembly 1121 specifically includes at least one adjustable cable storage baffle 11211. The base plate of the cable storage layer 1120 is machined with a plurality of arrayed mounting holes. Each adjustable cable storage baffle 11211 has one or more threaded holes or pins at its bottom that match the mounting holes. By passing fasteners (such as screws) through the selected mounting holes on the base plate and fixing them to the baffle 11211, it can be installed at any preset position within the cable storage layer 1120. When the cable storage space needs to be adjusted, simply loosen the fasteners, move the baffle 11211 to the new mounting hole position, and re-fix it. For example, when the reserved optical cable is small, multiple baffles 11211 can be installed close to each other to form a small coiling area; when more reserved optical cable needs to be added, the baffles 11211 can be moved outwards to expand the storage space, making the operation extremely flexible and convenient.

[0035] In a specific embodiment, see detailed description. Figure 1 The wiring layer 1110 serves as the core operating area, housing key components for fiber optic splicing operations. Specifically, the wiring layer 1110 contains at least one fusion splice tray 1111, which has multiple slots to securely support and protect the fiber optic splice point with heat-shrink tubing after the fiber core splicing is completed. Simultaneously, the wiring layer 1110 also contains a fixed adapter assembly 1112. This adapter assembly 1112 is a strip-shaped structure with a row of standardized mounting holes for installing different types of fiber optic adapters (also called flanges), such as SC and LC. One end of the adapter terminates the pigtail from the fusion splice tray 1111, while the other end connects to an external patch cord, enabling flexible scheduling and allocation of the optical path.

[0036] In a specific embodiment, see detailed description. Figure 1 To ensure a more standardized and neat fiber optic cabling within the wiring layer 1110 and to guarantee the bending radius of the fibers, at least one winding post 1113 is provided within the wiring layer 1110. The winding post 1113 is an arc-shaped or columnar structure, fixed to the base plate of the wiring layer 1110. Its main function is to provide a winding path that meets the minimum bending radius requirements for pigtails terminated on the adapter assembly 1112 or for patch cords used for optical path patching, preventing excessive fiber bending that could lead to excessive signal loss or fiber breakage. It also ensures clear and orderly internal cabling, facilitating management and maintenance.

[0037] In a specific embodiment, and referring to Figure 1 and Figure 2In terms of overall structure, the housing 1100 in this embodiment is physically composed of two distinct parts: a wiring layer housing that defines the space of the wiring layer 1110 and a cable storage layer housing that defines the space of the cable storage layer 1120. This split-structure design physically isolates the two functional layers. During installation, the cable storage layer 1120 housing is located directly below the wiring layer 1110 housing, together forming the complete form of the optical fiber splitter box 1000.

[0038] In a specific embodiment, and particularly understood Figure 2 To facilitate independent access and operation of the cable storage layer 1120, the housing of the wiring layer 1110 and the housing of the cable storage layer 1120 are connected by a snap-fit ​​mechanism. Specifically, they are pivotally connected on the long side of opposite sides via a hinge or similar pivoting structure. On the opposite side, they are detachably connected via one or more locking fasteners (unmarked thumbscrews or quick-release latches as shown in the figure). This design allows operators to unlock the fasteners and then flip the entire housing of the cable storage layer 1120 downwards to fully expose its internal space when access to the cable storage layer 1120 is needed. During this process, all splices and wiring within the wiring layer 1110 remain unchanged, greatly facilitating construction and maintenance.

[0039] In a specific embodiment, see detailed description. Figure 2 To accommodate the introduction of external optical cables, at least one cable inlet / outlet port 1122 is provided on the side wall of the cable storage layer 1120. To prevent the optical cable sheath from being scratched when passing through sharp metal or plastic openings, a rubber or soft plastic cable inlet / outlet coil 1123 is installed at each cable inlet / outlet port 1122 to provide a smooth transition. After the optical cable is introduced, to achieve effective mechanical fixation and prevent external pulling force from being directly transmitted to the fragile optical fiber, a fixing post 11212 for fixing the optical cable reinforcing core is also provided inside the cable storage layer 1120. The reinforcing core of the optical cable (usually metal wire or FRP) is stripped and securely fixed to the fixing post 11212, thereby achieving stress relief.

[0040] In a specific embodiment, see detailed description. Figure 1 After the fiber core bundle of the optical cable enters the upper wiring layer 1110 from the lower cable storage layer 1120 through the connecting channel 1130, a cable tie bridge 1114 is also provided in the wiring layer 1110 near the connecting channel 1130 for management and secondary fixation. The cable tie bridge 1114 has bridge-shaped holes or multiple parallel holes through which cable ties can pass. The fiber core bundle entering the wiring layer 1110 can be tied to the cable tie bridge 1114, which not only prevents the fiber core from shrinking back, but also makes the subsequent wiring to the splicing tray 1111 more neat and orderly.

[0041] In a specific embodiment, and referring to Figure 1 and Figure 2 The connecting channel 1130 is a crucial channel connecting the cable storage layer 1120 and the distribution layer 1110. Since the fiber core bundles, stripped of their outer sheaths, pass through this channel, a protective coil 1131 is also installed at the opening of the connecting channel 1130 to ensure they are not scratched or excessively bent by the channel edges during passage. The protective coil 1131 functions similarly to the protective coil 1123 at the cable entry and exit points, providing a smooth, rounded protective transition surface for the optical fiber.

[0042] In a specific embodiment, see detailed description. Figure 1 To protect the delicate components and fiber optic lines within the entire wiring layer 1110 from dust, moisture, and unauthorized personnel, the enclosure 1100 also includes an openable door assembly 1140. This door assembly 1140 is pivotally connected to the front opening of the wiring layer 1110 enclosure via hinges or similar means, allowing for easy opening and closing. When closed, the door assembly 1140 completely seals off the internal operating space of the wiring layer 1110 and is typically equipped with a lock for secure management of the entire fiber splitter box.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
