They can easily realize the connection, distribution and scheduling of optical fiber lines. Multiple fiber optic distribution frames with completed wiring can be installed in the cabinet for unified management. The trend of high density and modularization requires higher and higher density of optical fiber integrated in unit space.
[0003] High-density patch panels can integrate a large number of optical fibers and adopt a modular design, so that one patch panel can be equipped with multiple adapters and can split multiple optical cables;
[0004] When introducing optical cables into the current patch panel, the optical cables are introduced through the opening set at the rear of the patch panel. After the patch panel is installed in the cabinet, the optical cable introduction opening at the rear of the patch panel is located inside the cabinet. When the corresponding modules and optical cables need to be replaced at a later time, the patch panel needs to be disassembled from the cabinet as a whole, and a new optical cable needs to be introduced from the rear, and then the patch panel needs to be reinstalled on the cabinet. The operation is relatively cumbersome. In addition, since high-density patch panels integrate more optical fibers, when the patch panel is disassembled as a whole, the optical fibers on other modules will be dragged, affecting the stability of signal transmission.

[0028] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.
[0029] Combination Figure 1-Figure 4 As shown, the utility model provides a high-density optical fiber distribution frame, including a distribution box 1 and a module box 2. The front end surface of the distribution box 1 is provided with a plurality of slots 101, and the module boxes 2 corresponding to the number of the slots 101 are plugged into the distribution box 1 along the slots 101.
[0030] Combination Figure 1 and Figure 2 As shown, a card board 21 is provided at the first end of the module box 2, and a plurality of fiber optic adapters 22 are arranged in an array on the card board 21. An optical cable adapter 23 is provided at the second end of the module box 2. The plurality of fiber optic adapters 22 are connected to the optical cable adapter 23 via optical fibers. After the optical cable is introduced, the corresponding connector is used to connect to the optical cable adapter 23, so that the optical fiber inside the optical cable can be quickly connected to the optical fiber adapter 22.
[0031] In a specific embodiment, second fixing holes 201 are provided at both ends of the card plate 21, and threaded holes 102 corresponding to the second fixing holes 201 are provided at both ends of the slot 101. After the module box 2 is pushed into the wiring box 1 through the slot 101, the card plate 21 is attached to the outer side of the end face of the wiring box 1, and the second fixing holes 201 on the card plate 21 correspond to the threaded holes 102 on the end face of the wiring box 1. Then, screws are used to pass through the second fixing holes 201 and threadedly connected to the threaded holes 102 to fix the module box 2.
[0032] The optical fiber adapters 22 on the multiple module boxes 2 can be the same or different to accommodate a variety of wiring adapters.
[0033] Furthermore, a wire management plate 12 is fixed to the front end surface of the distribution box 1. The wire management plate 12 is provided with a plurality of wire management holes 104. External optical fibers pass through the wire management holes 104. The plurality of wire management holes 104 can classify and manage optical fiber bundles.
[0034] Combination Figure 1 As shown, connecting plates 11 are fixed on both sides of the front of the distribution box 1, and the connecting plate 11 is set to an L-shaped structure. A first fixing hole 103 is opened on one side of the connecting plate 11 parallel to the front end surface of the distribution box 1, and the first fixing hole 103 on the connecting plate 11 corresponds to the threaded hole on the cabinet. After the optical fiber wiring is completed, the distribution box 1 is installed on the cabinet through the connecting plate 11 and then fixed with screws.
[0035] At present, optical cables are introduced through the opening at the rear of the patch panel. After the patch panel is installed in the cabinet, the optical cable introduction opening at the rear of the patch panel is located inside the cabinet. When the corresponding modules and optical cables need to be replaced in the later stage, the patch panel needs to be removed from the cabinet as a whole, and a new optical cable needs to be introduced from the rear, and then the patch panel needs to be reinstalled on the cabinet. The operation is relatively cumbersome. In addition, since high-density patch panels integrate more optical fibers, when the patch panel is disassembled as a whole, the optical fibers on other modules will be dragged, affecting the stability of signal transmission.
[0036] Combination Figure 1 and Figure 2 As shown, both ends of the card board 21 are provided with optical cable introduction holes 202. When replacing and introducing a new optical cable, the corresponding module box 2 is pulled outward, and the optical cable is introduced through the optical cable introduction hole 202 opened on the card board 21, and then connected to the optical cable adapter 23. After the connection is completed, the module box 2 is pushed into the distribution box 1 through the slot 101, and the horizontal spacing between the outer sides of the two optical cable introduction holes 202 is less than the length of the slot 101, so that the optical cable can smoothly pass through the slot 101 into the distribution box 1, thereby realizing the introduction of the optical cable through the front end face of the distribution box 1, and there is no need to disassemble the entire distribution frame from the cabinet.
[0037] Furthermore, a support plate 3 is fixed to the second end of the module box 2, and a limiting component 4 is provided on the support plate 3 for limiting the bending radius of the optical cable. After the optical cable is introduced through the optical cable introduction hole 202, it changes its path along the limiting component 4, thereby connecting with the optical cable adapter 23.
[0038] In a specific embodiment, the limiting component 4 is configured as a circular ring structure with a fixed radius, which can limit the bending radius of the wound optical cable to prevent the optical cable from having a too small bending radius that affects transmission.
[0039] Furthermore, the top surface of the limiting component 4 is flush with the top surface of the module box 2 , so as to prevent the top surface of the limiting component 4 from protruding and interfering with the slot 101 .
[0040] Combination Figure 2 and Figure 3 As shown, a through optical cable groove 401 is provided on the limiting component 4, and the optical cable groove 401 corresponds to the optical cable adapter 23. The optical cable introduced from the tail can directly pass through the optical cable groove 401 and connect with the optical cable adapter 23 to avoid being blocked by the limiting component 4.
[0041] like Figure 4 As shown, the cross section of the limiting component 4 is set to an arc shape inclined outward. After the optical cable is wound, the optical cable can be limited in the height direction to prevent the optical cable from jumping out of the limiting component 4.
[0042] Combination Figure 2 and Figure 3 As shown, both sides of the module box 2 are provided with fixing components 5 for fixing the optical cable. After the optical cable enters through the optical cable introduction hole 202, it continues to be introduced along both sides of the module box 2. The optical cable is fixed by the fixing component 5 to make the path of the optical cable more regular, which is conducive to pushing and pulling the module box 2 along the slot 101.
[0043] In a specific embodiment, the fixing component 5 is configured as a C-shaped elastic buckle to facilitate fixing and disassembly.
[0044] In combination with the above embodiments, by setting the optical cable introduction hole 202 on the card board 21 of the module box 2, when replacing and introducing a new optical cable, the corresponding module box 2 is pulled outward, and the optical cable is introduced through the optical cable introduction hole 202 opened on the card board 21, and then connected with the optical cable adapter 23. After the connection is completed, the module box 2 is pushed into the wiring box 1 through the slot 101, and the horizontal spacing between the outer sides of the two optical cable introduction holes 202 is less than the length of the slot 101, so that the optical cable can smoothly pass through the slot 101 into the wiring box 1, thereby realizing the introduction of the optical cable through the front end surface of the wiring box 1, and there is no need to disassemble the wiring frame as a whole from the cabinet;
[0045] A limiting component 4 with a circular ring structure is provided at the rear end of the module box 2. After the optical cable is introduced through the optical cable introduction hole 202, the path is changed along the limiting component 4 with the circular ring structure, so as to be connected with the optical cable adapter 23. The limiting component 4 with the circular ring structure has a fixed radius, and can limit the bending radius of the wound optical cable to avoid the optical cable having a too small bending radius that affects the transmission.
[0046] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
