Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical fiber communication technology and relates to an optical fiber distribution frame. Background Technology
[0002] In the field of communications, optical fiber is an essential carrier for forming optical communication transmission network channels, and optical distribution frame (ODF) is an essential device for optical communication network terminals and relay sites to realize fiber routing, patching and access functions.
[0003] Fiber optic distribution frames need to be used in conjunction with fiber optic pre-terminated modules (fiber optic splicing modules). The back end of the fiber optic pre-terminated module is generally the trunk optical cable interface, while the front end has multiple neatly arranged fiber optic adapters (such as LC duplex ports, 12-core / 24-core / 48-core MTP / MPO ports). Fiber optic pre-terminated modules are available in various specifications (e.g., 8-core or 12-core) depending on the number of front-end fiber optic adapters.
[0004] Because different specifications of fiber optic pre-terminated modules have varying widths, and the mounting port size of fiber optic patch panels is designed to be a multiple of the width of a single fiber optic pre-terminated module, existing fiber optic patch panels can only accommodate one type of fiber optic pre-terminated module. For example, if a mounting port is designed to accommodate only two 8-core fiber optic pre-terminated modules, although a 12-core fiber optic pre-terminated module can be installed in that port, it will leave the port partially unfilled, wasting space. If two 12-core fiber optic pre-terminated modules are to be forcibly installed, they cannot be fitted, resulting in poor compatibility. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a fiber optic distribution frame.
[0006] The objective of this utility model can be achieved through the following technical solution: a fiber optic distribution frame, comprising:
[0007] The patch panel has at least one mounting port, and several connectors are evenly arranged along its width. The width of the mounting port is set to a common multiple of the widths of two different specifications of fiber optic pre-terminated modules. The mounting port is configured to be filled when a set number of first fiber optic pre-terminated modules are plugged in and / or a second fiber optic pre-terminated module is inserted.
[0008] Preferably, the mounting port is formed by a number of reference areas arranged sequentially, and each reference area is provided with a card holder. The width dimensions of the first fiber pre-terminated module and the second fiber pre-terminated module are both integer multiples of the width dimensions of the reference areas.
[0009] Preferably, the mounting port is formed by six reference regions arranged sequentially, the width of the first fiber pre-terminated module is equal to the width of two of the reference regions, and the width of the second fiber pre-terminated module is equal to the width of three of the reference regions.
[0010] Preferably, the front side of the wiring box is provided with a cable management module, the cable management module includes a front baffle and two cable management racks, the two cable management racks are respectively connected to the two sides of the front side of the wiring box, the two sides of the front baffle are respectively hinged to the two cable management racks, the front baffle can be rotated to a blocking position, and the front baffle is located in front of the mounting port when it is in the blocking position.
[0011] Preferably, the front baffle is hinged to and detachably connected to the cable management rack via a pluggable pin.
[0012] Preferably, the front baffle is provided with a snap-fit block, and the cable management rack is provided with a first elastic buckle. When the front baffle is in the blocked position, the snap-fit block engages with the first elastic buckle to restrict the rotation of the front baffle.
[0013] Preferably, the cable management rack is further provided with a second elastic buckle, and the cable management rack is detachably connected to the wiring box through the second elastic buckle.
[0014] Preferably, the rear side of the wiring box is provided with a rotatable rear baffle.
[0015] Preferably, the rear panel is provided with a hand-tightening screw, the rear panel can be rotated to a closed position, and the rear panel is connected to the wiring box through the hand-tightening screw when it is in the closed position.
[0016] Preferably, the rear baffle is hinged to and detachably connected to the wiring box via a resilient pin.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. The size of the mounting port is cleverly designed to be compatible with two different specifications of fiber optic pre-terminated modules. After a sufficient number of the two different specifications of fiber optic pre-terminated modules are inserted, the mounting hole can be filled perfectly, which greatly improves the compatibility of the patch panel.
[0019] 2. The front baffle can be rotated relative to the cable management rack via a pin. After the pin is pulled out, the front baffle can be completely removed from the cable management rack. With this design, the front baffle can be rotated and opened and closed via the pin, which is convenient for daily operation; in addition, the front baffle can be completely removed from the cable management rack, thereby completely removing the obstruction in front of the installation port, which is convenient for in-depth operation or in-depth maintenance.
[0020] 3. The rear panel can not only rotate to open and close, but also be completely disassembled. Its flexible pin structure facilitates quick installation and removal. After removing the rear panel, the top cover of the wiring box can slide open, providing technicians with access to the internal components. This design not only allows for flexible rotation and stable closure of the rear panel, but also supports rapid disassembly. Combined with the sliding top cover, this makes the internal operation of the wiring box more intuitive and efficient. Attached Figure Description

Detailed Implementation
[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0033] like Figure 1 As shown, a fiber optic patch panel includes: at least one patch box 100, the patch box 100 having at least one mounting port 110, the mounting port 110 having a plurality of connectors 120 evenly arranged along its width direction, the width of the mounting port 110 being set to a common multiple of the widths of two different specifications of fiber optic pre-terminated modules, and the mounting port 110 being configured to be in a filled state when a set number of first fiber optic pre-terminated modules 200 are plugged in and / or second fiber optic pre-terminated modules 300 are inserted.
[0034] The internal height of a patch panel 100 can be represented by "U". "U" is a standard unit of height specifically used for server racks or patch panels. 1U represents the height of one mounting unit, such as... Figure 2 , Figure 9 , Figure 10 As shown in the example, the height of the wiring box 100 can be 1U / 2U / 3U / 4U. For example... Figure 1 , Figure 2 As shown, the mounting port 110 is where the fiber optic pre-terminated module is inserted, and the snap-fit connector 120 is used for snapping the fiber optic pre-terminated module into place, thus securing the fiber optic pre-terminated module within the mounting port 110. The evenly distributed snap-fit connectors 120 allow the mounting port 110 to connect to two different specifications of fiber optic pre-terminated modules.
[0035] like Figure 1 As shown, the width of the mounting port 110 is specially designed. This width is a special value that is a common multiple of the widths of the two different fiber optic pre-terminated modules, ensuring that either type of fiber optic pre-terminated module can fill the mounting port 110 completely without any gaps. The advantage of this design is that it can fill both smaller and larger modules, or it can fill the mounting port 110 perfectly even when both types of modules are mixed.
[0036] For example, if the width of module A is 2N and the width of module B is 3N, then the width of mounting port 110 is 6N, and 3 modules A can be inserted into mounting port 110.
[0037] This type of patch panel has high compatibility, flexibility and space utilization. It allows you to choose which module to use as needed without wasting space or causing installation difficulties.
[0038] Based on the above implementation, the mounting port 110 is formed by a number of reference areas 111 arranged in sequence. Each reference area 111 is provided with a card holder 120. The width dimensions of the first fiber pre-terminated module 200 and the second fiber pre-terminated module 300 are both integer multiples of the width dimension of the reference area 111.
[0039] The reference area 111 can be understood as a minimum unit width, which is the basic unit for dividing the width of the entire mounting port 110. The width of each reference area 111 is N.
[0040] Based on the above implementation, the mounting port 110 is formed by six reference regions 111 arranged in sequence. The width of the first fiber pre-terminated module 200 is equal to the width of two reference regions 111, and the width of the second fiber pre-terminated module 300 is equal to the width of three reference regions 111.
[0041] In this example, the first fiber pre-terminated module 200 is preferably an 8-core module, which is relatively small with a width of 2N; the second fiber pre-terminated module 300 is preferably a 12-core module, which is relatively large with a width of 3N. Based on these dimensions, the least common multiple of the width of the mounting port 110 is 6N, thereby enabling the mounting port 110 to accommodate three first fiber pre-terminated modules 200 or two second fiber pre-terminated modules 300.
[0042] like Figures 2 to 5 As shown, a cable management module is provided on the front side of the wiring box 100. The cable management module includes a front baffle 500 and two cable management racks 400. The two cable management racks 400 are respectively connected to the two sides of the front side of the wiring box 100. The two sides of the front baffle 500 are respectively hinged to the two cable management racks 400. The front baffle 500 can be rotated to the blocking position. When the front baffle 500 is in the blocking position, it is in front of the mounting port 110.
[0043] The cable management rack 400 is used to organize and guide cables, preventing them from becoming tangled or interfering with each other. Simultaneously, the cable management rack 400 also supports the front baffle 500. The front baffle 500 can rotate to open / close like a door. When the front baffle 500 is in the blocked position, it is located directly in front of the mounting port 110, shielding and protecting it from dust entry and accidental contact with the fiber optic module. It also contributes to aesthetics and standardized cabling.
[0044] The front panel 500 can be opened and closed, making it convenient for technicians to insert and remove fiber optic modules and patch cords. When not in use, the front panel 500 can be closed to prevent accidental contact and dust contamination. The cable management rack 400 helps to organize patch cords, reduce tangling, and improve maintenance efficiency.
[0045] Based on the above implementation, the front baffle 500 is hinged to and detachably connected to the cable management rack 400 via a pluggable pin.
[0046] The front baffle 500 can be rotated relative to the cable management rack 400 via a pin. After the pin is pulled out, the front baffle 500 can be completely removed from the cable management rack 400. With this design, the front baffle 500 can be rotated and opened and closed via the pin, which is convenient for daily operation. In addition, the front baffle 500 can also be completely removed from the cable management rack 400, thereby completely removing the obstruction in front of the mounting port 110, which facilitates in-depth operation or in-depth maintenance.
[0047] Based on the above embodiments, the front baffle 500 is provided with a snap-fit block 510, and the cable management rack 400 is provided with a first elastic buckle 410. When the front baffle 500 is in the blocking position, the snap-fit block 510 snaps with the first elastic buckle 410 to restrict the rotation of the front baffle 500.
[0048] The snap-fit block 510 and the first elastic latch 410 constitute a positioning and locking structure to ensure that the front baffle 500 in the fiber optic distribution frame will not open or shake arbitrarily when closed. If it is necessary to open the front baffle 500, simply apply a certain force to pull it outward, causing the snap-fit block 510 to disengage from the latch.
[0049] Based on the above embodiments, the cable management rack 400 is also provided with a second elastic buckle 420, and the cable management rack 400 is detachably connected to the wiring box 100 through the second elastic buckle 420.
[0050] In actual operation, the cable management racks 400 located on both sides of the wiring box 100 may also obstruct operation. Therefore, the cable management racks 400 are designed to be detachably connected to the wiring box 100. The cable management racks 400 can be removed as needed to facilitate better operation.
[0051] like Figures 6 to 8 As shown, the front side of the wiring box 100 is provided with a cable management module, and the rear side of the wiring box 100 is provided with a rotatable rear baffle 600.
[0052] When needed, the rear panel 600 can be easily opened to expose the rear opening of the wiring box 100 for cable connection, splicing or maintenance. When the rear panel 600 is closed, it can seal the rear opening of the wiring box 100 to prevent dust from entering the box.
[0053] Based on the above implementation, the rear baffle 600 is provided with a hand-tightening screw 610, and the rear baffle 600 can be rotated to the closed position. When the rear baffle 600 is in the closed position, it is connected to the wiring box 100 through the hand-tightening screw 610.
[0054] In this design, the rear panel 600 can be connected to or disconnected from the wiring box 100 by manually tightening / loosening the hand screw 610. When the rear panel 600 is rotated to the "closed position", the screw is manually tightened to securely fix the rear panel 600 in the closed state. If it is necessary to open the rear panel 600, the hand screw 610 can be loosened and then the rear panel 600 can be opened.
[0055] Based on the above implementation, the rear baffle 600 is hinged to the wiring box 100 and detachably connected via an elastic pin 620.
[0056] The rear panel 600 can not only be rotated open and closed, but also be completely disassembled. The flexible pin 620 structure facilitates quick installation and removal. After removing the rear panel 600, the top cover of the wiring box 100 can be slid open, providing technicians with operating space for the internal components. This design not only enables flexible rotation and stable closure of the rear panel 600, but also supports quick disassembly. Combined with the sliding top cover, this makes the internal operation of the wiring box 100 more intuitive and efficient.
[0057] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0058] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0059] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0060] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
