Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fiber optic communication network terminal access equipment, and in particular relates to a fiber optic panel box. Background Technology
[0002] In FTTH network construction, fiber optic panel boxes are crucial equipment at the user end for securing optical cables, splicing fibers, and installing fiber optic adapters. Currently, most traditional fiber optic panel boxes on the market are designed based on the deployment requirements of early G.652D fiber, and have several drawbacks: First, the overall size of the product is large, occupying a lot of space and unable to adapt to the installation environment of standard distribution boxes in modern homes or offices; second, the installation method is limited, usually only supporting wall mounting, lacking flexibility; third, the method of securing the optical cable is often simple and crude, such as relying solely on cable ties, resulting in unreliable fixation. When the optical cable is subjected to external tension, the force is easily transmitted directly to the internal fiber core, potentially causing loosening or damage to fiber optic connectors, affecting communication quality.
[0003] Therefore, there is an urgent need for a new type of fiber optic panel box that is compact, versatile in installation, and capable of securely and reliably fixing optical cables. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of fiber optic panel box with a compact structure, firm fiber optic fixing, and support for multiple installation methods.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is an optical fiber panel box, including an upper cover and a bottom box. The upper cover and the bottom box are connected to form a closed cavity. The bottom of the bottom box is provided with an optical cable inlet, multiple cable bundling holes, and cable passage holes.
[0007] Multiple cable-binding holes form the fiber fixing and winding path, which is located outside the enclosed cavity. After the fiber enters from the cable inlet, it is guided by the fiber fixing and winding path to wind around the fiber entering from the cable inlet to form a tensile self-locking structure, and then passes through the cable holes into the enclosed cavity.
[0008] The bottom box is also provided with an optical fiber routing channel located in the enclosed cavity. The optical fiber routing channel is composed of multiple optical fiber baffles, which are used to guide the optical fiber to bend and coil.
[0009] The bottom box has an adapter mounting base on the side near the top cover.
[0010] As a preferred embodiment of this utility model, the number of cable bundling holes is four, which are arranged at the four corners of the bottom of the base box.
[0011] As a preferred technical solution of this utility model, the optical fiber baffle includes a plurality of first optical fiber baffles disposed on the bottom box side of the assembly edge of the upper cover and the bottom box, and a second optical fiber baffle and a third optical fiber baffle disposed inside the bottom box. The second optical fiber baffle and the third optical fiber baffle together constitute the optical fiber routing path, and the bending radius of the optical fiber bending and coiling is not less than 20mm.
[0012] As a preferred technical solution of this utility model, the bottom box is provided with a wall mounting hole, which is located in the island area of the optical fiber cable tray formed by the optical fiber baffle.
[0013] As a preferred technical solution of this utility model, the upper cover and the bottom box are detachably snapped together by a snap-fit structure. The snap-fit structure of the upper cover and the bottom box includes a plurality of inverted buckles provided in the upper cover. The inverted buckles are adapted to the slots on the edge of the bottom box to realize the detachable snap-fit between the upper cover and the bottom box.
[0014] As a preferred technical solution of this utility model, an electrical box guide rail snap-fit structure is also provided to support the installation of standard electrical box guide rails. The electrical box guide rail snap-fit structure includes a guide rail mounting buckle set at the bottom of the base box and a guide rail mounting position on the inner wall of the top cover.
[0015] As a preferred embodiment of this utility model, the upper cover is provided with an adapter mounting hole that matches the adapter mounting base, and a spare cable inlet is provided on one side of the upper cover.
[0016] This utility model has the following beneficial effects:
[0017] Compact structure and high space utilization: Through precise internal structural layout, the fiber fixing area, fiber coiling area and adapter installation area are clearly separated and organically combined, which greatly reduces the overall size of the product, making it particularly suitable for installation in standard electrical boxes with limited space.
[0018] The optical fiber is securely fixed and features a tensile self-locking function: A unique optical fiber fixing and winding path design guides the optical cable through multiple cable bundling holes, allowing it to wind around the bottom of the box in a large loop. When the optical cable is subjected to external tension, the winding cable generates friction against the walls of the cable bundling holes, achieving self-locking and effectively preventing the tension from being transmitted to the fragile internal optical fiber splices, thus ensuring the long-term stability of the line.
[0019] Effective protection of optical fiber: The internal optical fiber routing channel is equipped with a dedicated optical fiber routing channel, and the optical fiber is guided by the optical fiber baffle to be coiled in a figure-eight shape or a large arc shape, which strictly ensures that the bending radius of the optical fiber is not less than 20mm, which fully complies with communication standards and greatly reduces the optical signal attenuation caused by excessive bending.
[0020] The installation methods are flexible and diverse: it can be wall-mounted through the wall mounting holes on the bottom box, or it can be conveniently snapped onto a standard electrical box rail through the electrical box rail snap-fit structure, meeting the installation needs of different scenarios and having wider applicability.
[0021] Easy to assemble and low in cost: The top cover and bottom box are connected by a snap-fit mechanism, allowing for quick opening and closing without tools, facilitating construction and maintenance. The overall product structure is simple in design with few parts, reducing mold, production, and assembly costs.
[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0033] Please see Figures 1 to 5 The present invention provides an optical fiber panel box, the core of which consists of two main components: an upper cover 1 and a bottom box 2.
[0034] One end of the bottom of the housing 2 has an optical cable inlet 201 for introducing outdoor optical fibers. Multiple cable bundling holes 208 are also provided on the bottom panel of the housing 2. These cable bundling holes 208 together form a fiber fixing and winding path outside the enclosed chamber. During construction, after the optical fiber enters through the optical cable inlet 201, it does not directly enter the equipment. Instead, it is guided through these cable bundling holes 208 in sequence, making a loop around the bottom of the housing 2, and then passing through a cable through hole 205 into the enclosed internal chamber. This "looping" routing method ensures that when the optical cable is subjected to external tension, it tightly grips the walls of the cable bundling holes 208, generating significant friction and achieving tensile self-locking. The greater the external force, the tighter the self-locking, reliably protecting the internal optical fibers.
[0035] Within the enclosed cavity formed by the bottom box 2, there is a cable tray for coiling and guiding optical fibers. This tray mainly consists of multiple fiber baffles: a set of multiple first fiber baffles 202 located at the assembly edge of the top cover and the bottom box, whose function is to prevent the optical fibers from being damaged when the top cover is closed; the other two are a second fiber baffle 203 and a third fiber baffle 204 located inside the cavity of the bottom box 2. The second fiber baffle 203 and the third fiber baffle 204 cooperate with each other to naturally guide the spliced optical fiber pigtails into a figure-eight shape or a similar ring coil. This arrangement ensures that the bending radius of the optical fiber at any position is much greater than the safety standard of 20mm, effectively reducing macro-bending loss.
[0036] The base box 2 is also equipped with an independent wall mounting hole 207. The ingenious part is that the mounting hole is located in the center area of the "island" of the optical fiber winding path formed by the second optical fiber baffle 203 and the third optical fiber baffle 204. When screwing screws in here for wall mounting, it will not interfere with or compress the surrounding winding optical fibers at all, achieving a perfect combination of function and space.
[0037] An adapter mounting base 206 is also provided inside the cavity of the bottom box 2 for fixing fiber optic adapters 3 of types such as SC or LC. Correspondingly, an adapter mounting hole 103 matching the position and shape of the adapter mounting base 206 is provided on the front of the top cover 1 so that the interface of the fiber optic adapter 3 is exposed for the user to connect patch cords.
[0038] The upper cover 1 and the bottom box 2 are detachably connected via a snap-fit structure. Specifically, several inverted clips 101 are provided on the inner wall of the upper cover 1, while matching slots are provided on the edge of the bottom box 2. During assembly, simply align the upper cover 1 with the bottom box 2 and press it down; the inverted clips 101 will slide into the slots and lock in place. The connection is secure and requires no tools, greatly facilitating construction and maintenance.
[0039] To further enhance installation flexibility, this utility model also includes an electrical box rail locking structure. This structure includes rail mounting buckles 209 located on both sides of the bottom of the base box 2, and rail mounting positions 102 formed at corresponding positions on the inner wall of the upper cover 1. During installation, the mounting buckles 209 at the bottom of the base box 2 are first inserted into the holes of the standard electrical box rail 4. Then, the upper cover 1 is closed, and the mounting positions 102 on the inner wall of the upper cover 1 press down and clamp the rail 4, thus forming a very stable locking connection that meets the standardized installation requirements within the distribution box.
[0040] In addition, considering the variety of incoming cable directions, a spare cable inlet 104 is provided on one side of the top cover 1. When the user needs to enter the cable from the side, a hole can be made here to allow the optical cable to enter from this point, providing an effective supplement and alternative to the main inlet and enhancing the product's environmental adaptability.
[0041] The installation process of this utility model is as follows:
[0042] Fiber optic fixing: The optical cable is inserted into the optical cable inlet 201 of the bottom box 2 or the spare cable inlet 104 of the top cover 1, passes around multiple cable bundle holes 208 in sequence to form a self-locking structure, and finally passes through the cable hole 205 into the chamber, leaving an appropriate length.
[0043] Fiber optic splicing and coiling: Remove part of the outer sheath of the optical cable to expose the optical fiber, and splice it with the pigtail in the cavity. Place the spliced heat-shrinkable protective tube into the reserved position, and then coil the excess fiber pigtail around the second fiber baffle 203 and the third fiber baffle 204 in sequence into an "8" shape.
[0044] Install the adapter: Insert the pigtail connector into and secure it to the adapter 3 on the adapter mounting base 206.
[0045] Closing the lid: Align the top cover 1 with the bottom box 2 and press down gently. A "click" sound indicates that the inverted clip 101 of the top cover has been locked with the bottom box, and the installation is complete.
[0046] Final installation: Depending on the site environment, use screws to fix it to the wall through the wall mounting holes 207, or use the bottom box rail mounting buckle 209 and the top cover rail mounting position 102 to snap it onto the standard electrical box rail 4.
