Description

Technical Field

[0001] This utility model relates to the field of optical fiber connection technology, and in particular to a split-type optical fiber distribution box. Background Technology

[0002] Fiber optic distribution boxes are key devices in fiber optic access networks for the distribution and management of optical signals. Their core function is to centrally manage the access, branching, and protection of fiber optic lines. As a connection hub between optical fibers and user-end equipment, they distribute the backbone fiber to multiple branch fibers through fusion splicing or mechanical splicing techniques, enabling directional transmission of optical signals. The internal partitions of the fiber optic distribution box allow for internal conditioning and reduce fiber optic cable tangling and knotting.

[0003] Existing fiber optic distribution boxes lack corresponding partitioning structures. Without partitioning, multiple optical fibers are freely stacked inside the box, which can easily become tangled during maintenance. Forcibly pulling them may cause the optical fibers to break, requiring re-splicing, increasing maintenance costs and time. At the same time, tangled optical fibers are difficult to identify and handle quickly, requiring maintenance personnel to spend hours or even days troubleshooting, which seriously affects network repair efficiency. Utility Model Content

[0004] To overcome the problems of the messy interior of existing fiber optic distribution boxes, the difficulty for maintenance personnel to check fiber optic connections, and the stress concentration that can easily occur when the twisted fiber optic cables are subjected to external forces, leading to fiber optic cable breakage.

The lower baffle can extend downward through the cable passage. The partitioning component can move left and right in the mounting groove. Cable inlets are provided on the left and right sides of the cable boxes, and cable outlets are provided at the bottom of the cable boxes.

[0006] Preferably, a dovetail track is provided at the bottom of the mounting groove corresponding to the rear side of the wire passage. A dovetail groove slider is slidably connected on the dovetail track. A connecting plate is provided on the top of the dovetail groove slider. The dovetail groove slider can support the connecting plate to move along the length direction of the dovetail track.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a partitioned fiber optic distribution box, including a box 1. The front side of the box 1 has a mounting groove 10, and the rear side of the box 1 has a door 11 that can cover the mounting groove 10. The box 1 and the door 11 are connected by hinges. The bottom of the mounting groove 10 has a cable passage 101. Several cable boxes 3 are installed on the front side of the mounting groove 10. A partitioning assembly for partitioning the cable boxes 3 is provided inside the mounting groove 10. The partitioning assembly includes a connecting plate 241, and the top of the connecting plate 241 has an upwardly extending upper baffle 242. The bottom of box 41 has a downward-extending lower baffle 243, which can extend downward through the cable tray 101. The partition component can move left and right within the mounting groove 10. The left and right sides of the cable box 3 have cable inlet holes, and the bottom of the cable box 3 has cable outlet holes. The partition component facilitates the separation of the fiber optic cables inside the box 1 into different partitions, avoiding the clutter and lack of organization caused by too many fiber optic cables. The partition component can move left and right, facilitating the installation of cable boxes 3 of different sizes and increasing applicability. The lower baffle 243 can extend downward through the cable tray. The opening 101 extends downwards, allowing workers to observe the fiber optic cable arrangement inside the box 1 without opening the box door 11. A dovetail track 251 is located at the bottom of the mounting groove 10, corresponding to the rear side of the cable opening 101. A dovetail slide block 252 is slidably connected to the dovetail track 251. A connecting plate 241 is located at the top of the dovetail slide block 252. The dovetail slide block 252 can support the connecting plate 241 to move along the length of the dovetail track 251. The low-cost dovetail track 251 and dovetail slide block 252 reduce production costs. 251 restricts the movement direction of the dovetail slide block 252, so that the separating component can only move left and right. A screw 21 connecting the left and right sides of the mounting groove 10 is provided in the mounting groove 10. The screw 21 is located in front of the dovetail track 251. A sliding block 22 is sleeved on the outer diameter of the screw 21. A through hole is provided on the left side of the sliding block 22. The outer diameter of the through hole is the same as the outer diameter of the screw 21. A connecting plate 241 is provided on the top of the sliding block 22. Because the outer diameter of the through hole is the same as the outer diameter of the screw 21, the sliding block 22 can move left and right without being twisted.

[0023] Please see Figure 2 - Figure 5 In this embodiment, a positioning nut 23 is helically engaged at the outer diameter of the screw 21. The left and right sides of each sliding block 22 can respectively abut the positioning nut 23. The two positioning nuts 23 on the left and right sides of the sliding block 22 tightly abut against it, achieving the function of positioning the sliding block 22 and preventing it from moving easily without adjustment. The cable box 3 includes a front cover 31. A plate 331 is provided at the rear of the cable box 3 corresponding to the cable outlet hole. A plate 333 is provided below the front of the plate 331. A plate 332 protrudes upwards from the front of the top of the plate 333. A fiber optic adapter 32 is provided on the front of the plate 332. By providing the fiber optic adapter 32 on the front of the plate 332, the fiber optic cable can be inserted horizontally, avoiding the falling phenomenon caused by vertical insertion. The fiber optic adapter 32 includes components capable of... The fiber optic plug is inserted into connector ports 1 and 2. Connector port 1 is located on the rear side of board 2 332, and connector port 2 is located on the front side of board 2 332. The fiber optic cable is connected through connector ports 1 and 2 of the fiber optic adapter 32, which facilitates the transmission of fiber optic signals out of box 1 through connector port 2. The bottom of board 3 333 is located above the bottom of the lower baffle 243, and the rear side of the upper baffle 242 is located behind the front side of the cover 31. The front and rear sides of the lower baffle 243 can fit against the front and rear sides of the cable passage 101. The bottom of board 3 333 is located above the bottom of the lower baffle 243, and the rear side of the upper baffle 242 is located behind the front side of the cover 31. The front and rear sides of the lower baffle 243 can fit against the front and rear sides of the cable passage 101 to achieve complete separation of fiber optic cables and reduce the occurrence of fiber optic cables from different separated areas mixing together.

[0024] During operation, the worker opens cover 31 and connects the main fiber optic cable through the inlet port on any side of the junction box 3. The main fiber optic cable contains several branch fiber optic cables. The junction box 3 and the main fiber optic cable are existing technologies, while the connection ports and fixing methods of the branch fiber optic cables are well-known to those skilled in the art. Then, an adapter fiber optic cable is used to connect to port one of the fiber optic adapter 32, and then an incoming fiber optic cable is used to connect to port two of the fiber optic adapter 32. The incoming fiber optic cable passes through port 101. When dealing with junction boxes 3 of different sizes, the worker can rotate the slider to adjust its position. The positioning nuts 23 on both sides of block 22 are used to move the sliding block 22. The dovetail slider 252 will slide on the dovetail track 251 to prevent movement in the front and back directions. After it is moved into place, the positioning nuts 23 on both sides of the sliding block 22 can be tightened with a wrench. The lower baffle 243 separates the incoming fiber optic cables to prevent a large number of incoming fiber optic cables from mixing together and causing chaos, which is convenient for troubleshooting when an abnormality occurs. The door 11 is equipped with a door lock to lock the box 1. The box 1 covers the junction box 3 to reduce the possibility of water entering the junction box 3 due to rain.

[0025] Through the above steps, the dividing component facilitates the separation of the optical fiber lines inside the box 1 into different partitions. The dividing component can move left and right, and the lower baffle 243 can extend downward through the cable outlet 101 to solve the problems of the existing optical fiber distribution box being relatively messy, making it difficult for maintenance personnel to check the optical fiber connection, and the tangled optical fiber being prone to stress concentration when subjected to external force, leading to the breakage of the optical fiber.
