Description

Technical Field

[0001] This utility model relates to the field of optical fiber equipment, specifically a miniature optical cable splitter box. Background Technology

[0002] The advent of the information society has led to a continuous increase in people's demand for information. The rapid development of emerging businesses, especially the even greater demand for video information, has once again placed higher demands on network transmission. The rapid development of fiber optic technology and the gradual maturity of access technology have made it possible to realize all people's ideas. The transmission bandwidth and distance that fiber optics can provide are almost unlimited, laying the foundation for building fiber optic access networks.

[0003] FTTH is the ultimate goal and the most ideal access method for fiber optic access. As an important access device connecting users and networks, optical cable distribution boxes and optical cable distribution boxes are increasingly widely used in FTTH technology. However, traditional optical cable distribution boxes are not only large in size, use a large number of adapters, and are expensive, but also have large input and output losses when connecting adapters, and messy internal wiring, which is not conducive to later maintenance and causes great inconvenience to maintenance personnel.

[0004] To address the aforementioned issues, a search revealed Chinese patent CN202649548U, which discloses a novel optical fiber distribution box. The box includes a transparent PVC sheet, a flip-up partition, a lid, a bottom, a plastic key, a metal lock, rubber blocks, a wall-mounting component, rubber plugs, protective tube fixing rubber, a PG clamp, a steel wire clamp, and an adapter mounting strip. The bottom and lid are connected by a hinge, and the flip-up partition is positioned near the hinge on the bottom. The adapter mounting strip is snapped onto the front of the flip-up partition, and the transparent PVC sheet is snapped onto the back.

[0005] While the aforementioned device increases the number of users it can connect to and the flip-up inner cover makes full use of space, in actual use, the fiber distribution box installed outdoors lacks resistance to scratches from sharp objects, which may cause scratches on the surface of the box, damaging its appearance integrity. If the scratches are deep, they may also affect the sealing and structural strength of the box. Utility Model Content

[0006] The purpose of this invention is to provide a miniature optical fiber splitter box to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, a miniature optical fiber splitter box is provided, comprising a splitter box base and a splitter box cover. A sealing seat A is fixedly connected to the top of the splitter box base, and a sealing seat B covers the surface of the sealing seat A. The splitter box cover is fixedly installed on the top of the sealing seat B. An upper protective frame covers the outer side of the splitter box cover, and a lower protective frame covers the outer side of the splitter box base. Lower docking grooves are provided on both sides of the surface of the sealing seat A, and upper docking grooves are provided on both sides of the surface of the sealing seat B. The upper and lower protective frames are fixedly connected to the outside of the splitter box through docking mechanisms A and B.

[0008] Furthermore, the upper and lower protective frames are combined to form the protective structure of the fiber distribution box, and the upper and lower protective frames are detachable on the outside of the fiber distribution box.

[0009] Furthermore, the upper and lower protective frames have the same structural composition. The upper protective frame is composed of warp strips and weft strips, and both warp strips and weft strips are set in multiple groups. The included angle between the warp strips and weft strips is 90 degrees.

[0010] Furthermore, the docking mechanism A and docking mechanism B have the same structure. The docking mechanism A consists of an upper docking piece, a lower docking piece, an upper splicing piece, and a lower splicing piece. The upper docking pieces are fixedly installed on both sides of the bottom of the upper protective frame, and the lower docking pieces are fixedly installed on both sides of the top of the lower protective frame.

[0011] Furthermore, both ends of the lower and upper connecting plates are arc-shaped, and four sets of screw holes are evenly provided on the lower and upper connecting plates. The lower and upper connecting plates are fixedly connected by screw holes and bolts.

[0012] Furthermore, an upper splicing piece is fixedly installed on the inner wall of the upper docking piece, and a lower splicing piece is fixedly installed on the inner wall of the lower docking piece. The cross-sections of the upper splicing piece and the upper docking groove are both dovetail-shaped, and the cross-sections of the lower splicing piece and the lower docking groove are both dovetail-shaped.

[0013] Furthermore, the lower splicing piece is positioned and inserted inside the lower docking groove and fixed with bolts, while the upper splicing piece is positioned and inserted inside the upper docking groove and fixed with bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a pull-out installation method for the upper and lower protective frames, allowing them to be quickly attached to the outside of the fiber distribution box. When the fiber distribution box needs to be inspected, maintained, or spliced ​​with optical fibers, the protective frames can be quickly opened by pulling them out, eliminating the need to disassemble complex fixing devices, saving operation time and improving maintenance efficiency. After maintenance, the protective frames can be quickly pushed back into place to restore the protective state. In some space-constrained locations, the pull-out protective frames can be pulled out along the side of the fiber distribution box without occupying additional space. Compared with traditional detachable protective structures, this design saves more space and is better suited to confined installation environments.

[0016] 2. This utility model uses an upper protective frame and a lower protective frame combined together to form a protective structure for the fiber splitter box, which can effectively resist external collisions, squeezing and scratches, and protect the fiber splitter box from physical damage; in the construction site or daily operation and maintenance, it can prevent damage to the fiber splitter box caused by tools falling or human collisions, and ensure that the internal optical fiber connection and splitting device are not affected, and maintain the normal transmission of optical signals.

[0024] Please see Figure 1-6This utility model provides a miniature optical fiber splitter box, including a splitter box base 1 and a splitter box cover 3. A sealing seat A2 is fixedly connected to the top of the splitter box base 1. A sealing seat B4 covers the surface of the sealing seat A2. The splitter box cover 3 is fixedly installed on the top of the sealing seat B4. An upper protective frame 5 covers the outside of the splitter box cover 3. A lower protective frame 6 covers the outside of the splitter box base 1. Lower docking grooves 21 are opened on both sides of the surface of the sealing seat A2. Upper docking grooves 41 are opened on both sides of the surface of the sealing seat B4. The upper protective frame 5 and the lower protective frame 6 are fixedly connected to the outside of the splitter box through docking mechanisms A7 and B8.

[0025] Working principle: In actual use, the upper protective frame 5 and the lower protective frame 6 are installed on the outside of the fiber splitter box. The upper protective frame 5 and the lower protective frame 6 together form the protective structure of the fiber splitter box, which can effectively resist external collisions, squeezing and scratches, and protect the fiber splitter box from physical damage. In the construction site or daily operation and maintenance, it can prevent damage to the fiber splitter box caused by tools falling or human collisions, and ensure that the internal optical fiber connection and splitting device are not affected, and maintain the normal transmission of optical signals.

[0026] The installation method of the upper protective frame 5 is as follows: Align the upper splicing pieces 73 on both sides of the bottom of the upper protective frame 5 with the upper mating grooves 41 located on both sides of the sealing seat B4, and align the lower splicing pieces 74 on both sides of the upper part of the lower protective frame 6 with the lower mating grooves 21 located on both sides of the sealing seat A2. At this time, the lower splicing pieces 74 are inserted into the lower mating grooves 21 and fixed with bolts, while the upper splicing pieces 73 are inserted into the upper mating grooves 41 and fixed with bolts. This pull-out installation method is simpler and faster in actual operation. Finally, screw the two sets of upper mating pieces 71 and lower mating pieces 72 together. The upper protective frame 5 and lower protective frame 6 can be quickly attached to the outside of the fiber distribution box using a pull-out installation method. When it is necessary to inspect, maintain, or perform fiber splicing operations on the fiber distribution box, the protective frame can be quickly opened by pulling out, without disassembling complex fixing devices, saving operation time and improving maintenance efficiency. After maintenance, the protective frame can be quickly pushed back into place to restore the protective state. In some space-constrained places, the pull-out protective frame can be pulled out along the side of the fiber distribution box without occupying additional space. Compared with the traditional detachable protective structure, it saves more space and can better adapt to the narrow installation environment.

[0027] In a preferred embodiment, the upper protective frame 5 and the lower protective frame 6 are combined together to form the protective structure of the fiber distribution box, and the upper protective frame 5 and the lower protective frame 6 are detachable structures on the outside of the fiber distribution box.

[0028] In a preferred embodiment, the upper protective frame 5 and the lower protective frame 6 have the same composition structure. The upper protective frame 5 is composed of warp strips 51 and weft strips 52. Both warp strips 51 and weft strips 52 are set in multiple groups, and the included angle between warp strips 51 and weft strips 52 is 90 degrees.

[0029] The upper protective frame (5) and the lower protective frame (6) are designed in a grid shape. The grid structure has many holes, which can form an air convection channel, which is conducive to the heat inside the fiber distribution box being dissipated to the external environment. When the fiber distribution box is working, especially under high load or high temperature conditions, it can effectively reduce the internal temperature, prevent the equipment from degrading or malfunctioning due to overheating, and extend the service life of the fiber distribution box and its internal components.

[0030] As a preferred embodiment, docking mechanism A7 and docking mechanism B8 have the same composition structure. Docking mechanism A7 is composed of upper docking piece 71, lower docking piece 72, upper splicing piece 73 and lower splicing piece 74.

[0031] In a preferred embodiment, both ends of the lower connecting piece 72 and the upper connecting piece 71 are arc-shaped, and four sets of screw holes are evenly provided on the lower connecting piece 72 and the upper connecting piece 71. The lower connecting piece 72 and the upper connecting piece 71 are fixedly connected by screw holes and bolts.

[0032] In a preferred embodiment, an upper splicing piece 73 is fixedly installed on the inner wall of the upper connecting piece 71, and a lower splicing piece 74 is fixedly installed on the inner wall of the lower connecting piece 72. The cross-sections of the upper splicing piece 73 and the upper connecting groove 41 are both dovetail-shaped, and the cross-sections of the lower splicing piece 74 and the lower connecting groove 21 are both dovetail-shaped.
