Description
Technical Field
[0001] This utility model relates to the field of optical cable junction box technology, and more specifically, to an integrated optical cable junction box. Background Technology
[0002] As a key node device in fiber optic communication networks, the fiber optic junction box undertakes important functions such as connecting, distributing, and scheduling fiber optic lines, and its performance directly affects the stability and scalability of the communication network. With the rapid increase in the number of fiber optic access users, traditional fiber optic junction boxes, due to their limited capacity, chaotic internal layout, inconvenient adapter installation, and difficult maintenance, can no longer meet the high-efficiency operation and maintenance requirements of modern communication networks.
[0003] In existing technologies, for example, patent CN120539895B proposes a large-capacity optical cable junction box that facilitates adapter installation. By setting up a double-layer installation module and a winding reel structure, it improves the utilization rate of the box space and the efficiency of adapter installation. However, it still has shortcomings in terms of line protection during optical cable maintenance. The optical cable is easily damaged by compression and entanglement when frequently pulled out. On the other hand, patent CN223065575U focuses on maintenance convenience. It avoids bending damage to the optical cable when pushing it into the box by using optical cable take-up and drop components and a limiting rod structure. However, this design does not optimize the adapter installation and the large-capacity storage of fiber optic patch cords, resulting in poor adaptability when dealing with high-density optical cable deployment.

Detailed Implementation
[0020] The following is a detailed description of the embodiments, in conjunction with the accompanying drawings.
[0021] Reference Figure 1 , Figure 4An integrated optical cable junction box includes: a box body 1, a mounting bracket 2, an integrated tray housing 3, an ODF fiber optic distribution frame 4, and a cabling assembly 6. The mounting bracket 2 is disposed inside the box body 1. The integrated tray housing 3 and the ODF fiber optic distribution frame 4 are detachably mounted on the mounting bracket 2. The cabling assembly 6 is provided with cabling holes 601, which are through holes. The box body 1 can be made of high-strength metal materials (such as galvanized steel sheet) or engineering plastics, and has waterproof, dustproof, and corrosion-resistant properties, making it suitable for outdoor or indoor environments. The mounting bracket 2 can be fixed to the bottom plate, rear wall, or side wall inside the box body 1, serving as the main support structure. The mounting bracket 2 can adopt a modular design, for example, composed of longitudinal guide rails and transverse beams, forming a grid-like or track-like frame. The bracket has standardized mounting holes or slots, allowing the components to be flexibly installed in different positions. The mounting bracket 2 can be connected to the box body 1 by screws or welding to ensure stability. The integrated tray housing 3 is detachably mounted on the mounting bracket 2 using screws or clips, and can be arranged horizontally or vertically as needed. For example, users can increase or decrease the number of adapter trays according to port requirements. Each adapter tray is installed independently and supports hot-swappable replacement. The ODF fiber optic patch panel 4 includes patch rings, winding posts, and management panels for organizing, routing, and storing patch cords. The ODF fiber optic patch panel 4 is also detachably mounted on the mounting bracket 2 using methods such as quick-release screws or slide rails. The ODF fiber optic patch panel 4 can be located adjacent to the integrated tray housing 3 to optimize the patch cord path. The size and position of the ODF fiber optic patch panel 4 can be flexibly adjusted according to the number of patch cords to avoid fiber entanglement and damage. The cabling assembly 6 can adopt a plate-like or channel-like structure, made of engineering plastics or metal materials (such as galvanized steel sheet). The cabling hole 601 is a through hole that penetrates the entire assembly. Its shape can be circular, square, or elliptical, and the hole diameter is based on the fiber diameter. The edges are smoothed (such as chamfered or rubber bushing) to prevent the fiber from being worn or cut during cabling. The cabling assembly 6 connects to the mounting bracket 2 via a standardized interface, secured using mechanisms such as screws, clips, or slide rails. Pre-set mounting points (such as threaded holes or slots) on the gridded frame of the mounting bracket 2 (e.g., longitudinal guide rails and transverse beams) are designed to match the cabling assembly 6. The cabling assembly 6 works in conjunction with other components within the enclosure 1. After the patch cord emerges from the interface 301 of the integrated tray housing 3, it preferentially passes through the cabling hole 601 before being routed to the winding post or management panel of the ODF fiber optic distribution frame 4. The orderly guidance and securing of the patch cord through the cabling hole 601 effectively prevents it from crossing, tangling, or excessively bending within the enclosure, reducing signal loss and physical damage risks caused by cable twisting or friction. This extends the fiber optic lifespan and reduces misoperations caused by messy cabling during maintenance.
[0022] In some embodiments, there are several integrated tray housings 3, which are evenly spaced and mounted on the mounting bracket 2. Each integrated tray housing 3 is designed as an independent functional unit (or module); on the back or sides of each integrated tray housing module, there are mounting ears corresponding to the threaded holes on the mounting bracket. For example, the integrated tray housing 3 can be a tray or module box containing 12-core or 24-core welding capacity and equipped with a corresponding number of adapters (such as SC, LC). The mounting bracket 2 can adopt a grid-like or rail-type design. For example, a series of mounting points (such as threaded holes, snap-fit interfaces) are set on the longitudinal guide rail at fixed intervals (such as multiples of 1U or 25 mm). This evenly distributed mounting point provides a physical basis for the evenly spaced installation of the integrated tray housings 3. The installer only needs to align each module with the preset positioning point on the bracket and fix it.
[0023] In some embodiments, refer to Figure 3 Each integrated tray housing 3 has several interfaces 301 arranged in an array on the integrated tray housing 3. The interfaces 301 maintain a fixed and uniform spacing in both the horizontal and vertical directions. This arrangement is similar to the RJ45 port arrangement in a network patch panel, which is neat and orderly. Each interface 301 can be of the same type (e.g., all SC interfaces or all LC interfaces) or multiple types (e.g., a mix of SC and LC interfaces) arranged in a predetermined order to meet different connection requirements. Next to the array (e.g., on the left or below), there is a corresponding label area to clearly identify the fiber core sequence or routing information corresponding to each interface, which corresponds one-to-one with the array distribution of the physical interfaces for easy and quick location.
[0024] In some embodiments, refer to Figure 2The mounting bracket 2 includes a lower crossbeam 201, a support plate 202, and an upper crossbeam 203. The support plate 202 is vertically mounted on the lower crossbeam 201, and its upper end is connected to the upper crossbeam 203. Both the lower crossbeam 201 and the upper crossbeam 203 are connected to the inner side of the enclosure 1. Multiple support plates 202 can be provided, with threaded holes or through holes punched at standard intervals (e.g., 25mm or 1U height) on them. Several sets of parallel slots or guide rails are provided in the vertical direction. Each integrated tray housing 3 serves as a pull-out tray, allowing for easy pushing and pulling in and out like a server hard drive. This method allows maintenance personnel to pull the entire module out of the enclosure without interrupting fiber optic connections, enabling comprehensive welding, patching, and maintenance operations, greatly improving convenience. Maintenance personnel can freely plan the positions of the welding area, adapter area, and patching management area on the support plate 202 according to actual needs. For example, commonly used adapter modules can be installed in the central area, which is most convenient for both sight and operation. This orderly layout makes fiber optic patching paths shorter and clearer, greatly reducing fiber crossings and tangles, and lowering maintenance difficulty and the risk of misoperation.
[0025] In some embodiments, a power supply component 5 is also included, which is detachably mounted on the mounting bracket 2. During the initial construction phase, if no power supply is required, the power supply component 5 can be omitted, saving cost and space. When future business development necessitates the addition of intelligent monitoring or other active devices, the power supply component 5 can be simply added to the empty space of the mounting bracket 2, just like adding an integrated tray housing 3, without replacing the entire enclosure or undertaking complex modifications.
[0026] In some embodiments, a plurality of protrusions are provided on the inner wall of the cable routing hole 601, and the plurality of protrusions are arranged in an array on the inner wall of the cable routing hole 601. The arrayed protrusions form uniform support points, which helps the jumper to maintain a preset path within the cable routing hole and avoid slippage or displacement. This design makes the jumper routing more regular, reduces the crossing and tangling of jumpers within the box, and reduces maintenance complexity.
[0027] In some embodiments, refer to Figure 5 , Figure 6A cable limiting component 602 is detachably installed at the cable routing hole 601. The outer diameter of the cable limiting component 602 matches the inner diameter of the cable routing hole 601. Several clamping bodies 6022 are provided at the front end of the cable limiting component 602, evenly surrounding the axis of the cable limiting component 602 and forming a clamping hole 6021 in the center. The clamping hole 6021 passes through both ends of the cable limiting component 602. A thread 6023 is provided at the rear end of the cable limiting component 602. The cable limiting component 602 is made of engineering plastic or elastic rubber material, possessing wear-resistant and aging-resistant properties. The outer diameter of the cable limiting component 602 matches the inner diameter of the cable routing hole 601, allowing the cable limiting component 602 to be detachably embedded in the cable routing hole 601 through an interference fit or a snap-fit mechanism. The thread 6023 at the rear end can be screwed and fixed with the threaded hole on the inner wall of the cable routing hole 601, achieving stable installation and facilitating disassembly and replacement. The front end of the cable limiting component 602 is designed with multiple elastic clamping bodies 6022 (usually 4-6). These clamping bodies are evenly distributed around the axis of the limiting component, forming a central clamping hole 6021. The clamping bodies 6022 have a certain degree of elasticity and opening and closing capability. The initial diameter of the clamping hole 6021 is slightly smaller than the diameter of a standard jumper (for example, an initial hole diameter of 1.5 mm, suitable for jumpers with a diameter of 2.0 mm), thereby generating a clamping force when the jumper passes through. When wiring inside the enclosure, after the jumper is led out from the interface 301 of the integrated tray housing 3, it preferentially passes through the clamping hole 6021 of the cable limiting component 602. Due to the small diameter of the clamping hole 6021, the jumper squeezes the clamping body 6022 when it enters, causing it to elastically expand outward, forming a uniform grip on the jumper. After the jumper passes through, the clamping body 6022 tightly wraps around the surface of the jumper under the action of elastic restoring force, preventing the jumper from sliding or falling out in the hole. Meanwhile, the threaded 6023 structure allows for adjustment of the depth of the limiting component in the cable routing hole 601 to accommodate different bending radii of the jumper. When the jumper needs to be replaced or maintained, maintenance personnel can rotate or pull out the cable limiting component 602, and the clamp body 6022 will automatically release the jumper, enabling quick operation without disassembling other components.
[0028] In some embodiments, there are multiple routing holes 601, which are arrayed on the cabling assembly 6. Through these arrayed routing holes, patch cords can be systematically guided and fixed at different locations, forming standardized routing paths. This design avoids the problem of patch cords randomly crossing and tangling in traditional junction boxes, making the cabling inside the box neater and clearer, and significantly reducing maintenance difficulty and the risk of misoperation caused by messy cables.
[0029] In some embodiments, a first door panel 101 and a second door panel 102 are hinged to the front and back of the enclosure 1, respectively. This dual-door design allows bidirectional access to the interior of the enclosure from both the front and back. Maintenance personnel can open the first door panel 101 to operate the integrated tray housing 3 and the ODF fiber optic patch panel 4 from the front, while simultaneously opening the second door panel 102 to introduce or manage incoming / outgoing optical cables from the back. This bidirectional access reduces blind spots, making fiber splicing, patching, and cable routing more convenient and significantly improving maintenance efficiency.
[0030] In some embodiments, the surface of the enclosure 1 is provided with an anti-rust coating. A multi-layer composite coating system can be used. The primer can be an epoxy zinc-rich primer or an epoxy zinc phosphate primer with excellent anti-rust properties and adhesion. The zinc powder in the primer provides cathodic protection; even if the coating is slightly damaged, it can protect the steel substrate by preferentially corroding the zinc powder through electrochemical action. The topcoat can be a coating with extremely high weather resistance, such as polyester powder coating or fluorocarbon coating. These topcoats have excellent resistance to ultraviolet rays, acids and alkalis, salt spray, and aging, and can maintain color and gloss for a long time, resisting the erosion of outdoor sun and rain. The anti-rust coating forms a strong physical and chemical barrier between the metal surface of the enclosure and the moisture, oxygen, salt (in coastal areas), and pollutants in the environment, effectively preventing electrochemical corrosion. This allows the junction box to work stably in harsh outdoor environments such as humidity, acid rain, and industrial atmospheres for a long time, extending the service life of the enclosure from a few years to more than ten years or even longer, reducing the equipment replacement cost over the overall life cycle.
