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 with a tray. 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] One of the core functions of a fiber optic patch panel is to house and secure fiber optic cabling modules (i.e., fiber optic adapters). Currently, mainstream designs typically use mounting ports for module insertion and fixation. However, this design struggles to support the high-density integration of fiber optic cabling modules. When debugging, replacing, or performing routine maintenance on a specific fiber optic cabling module, the operator must first remove the target module from the mounting port. As the density of integrated modules within the patch panel increases (i.e., the number of modules increases and their arrangement becomes more compact), the spatial gaps between cabling modules shrink dramatically. Under these circumstances, removing a single cabling module becomes extremely cumbersome and difficult. Therefore, existing fiber optic patch panels cannot simultaneously meet the demands of dense module arrangement and convenient operation, leaving room for improvement. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a fiber optic distribution frame with a tray.
[0005] The objective of this utility model can be achieved through the following technical solution: a fiber optic distribution frame with a tray, comprising:
[0006] A wiring box module, wherein guide rail seats are provided on both sides of the wiring box module, and the guide rail seats are provided with at least one guide rail groove;
[0007] At least one tray module, the tray module including a tray plate and two side slide bars, the two side slide bars being fixed to both sides of the tray plate respectively, and the two side slide bars being slidably connected to the guide rail grooves of the two guide rail seats respectively, so that the tray plate is slidably connected to the wiring box module.
[0008] Preferably, there are multiple tray modules, and each tray module is arranged sequentially along the height or width direction of the wiring box module. The number of guide rail slots on the guide rail base is the same as the number of tray modules and they are set one-to-one.
[0009] Preferably, the guide rail groove is provided with a limit stop, the side slide bar is provided with a first elastic buckle, the sliding stroke position of the tray includes a retracted position, when the tray is in the retracted position, the first elastic buckle abuts against the limit stop and restricts the tray from extending, and the first elastic buckle can separate from the limit stop through elastic deformation to allow the tray to extend.
[0010] Preferably, the side slide bar is further provided with a second elastic buckle, and the sliding stroke position of the tray also includes an extended position. When the tray is in the extended position, the second elastic buckle abuts against the limiting block to restrict the tray from detaching from the wiring box module. The second elastic buckle can separate from the limiting block through elastic deformation to allow the tray to cross the extended position and separate from the wiring box module.
[0011] Preferably, the tray is provided with a snap-fit structure for snapping in the wiring module.
[0012] Preferably, the front side of the wiring box module is provided with a front opening, and the tray extends out or retracts into the wiring box module through the front opening.
[0013] Preferably, it also includes a front baffle, which is hinged to the front side of the wiring box module. The front baffle can be rotated to an open state or a closed state. When the front baffle is in the open state, the front opening is exposed, and when the front baffle is in the closed state, the front opening is closed.
[0014] Preferably, the wiring box module is provided with two hinges, and the two sides of the front baffle are hinged to the wiring box module through the two hinges. The hinge includes a flexible part, a first rigid part, and a second rigid part. The first rigid part and the second rigid part are respectively located at both ends of the flexible part. The first rigid part and the second rigid part are respectively provided with a first connecting hole and a second connecting hole. The wiring box module is provided with a first plug, and the front baffle is provided with a second plug. The first plug is inserted into the first connecting hole to make the hinge detachably connected to the wiring box module, and the second plug is inserted into the second connecting hole to make the hinge detachably connected to the front baffle.
[0015] Preferably, the wiring box module is further provided with one of a locking seat and a locking block, and the front baffle is provided with the other of a locking seat and a locking block. When the front baffle is in the closed state, the locking block and the locking seat engage to restrict the rotation of the front baffle.
[0016] Preferably, one of the locking seat and the locking block is provided with a third connecting hole, and the wiring box module is also provided with a third plug, which is plugged into the third connecting hole.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. It can support the high-density integrated assembly of fiber optic wiring modules through the various tray modules inside the wiring box module, and the tray modules can be pulled out to easily operate the corresponding fiber optic wiring modules, thus simultaneously meeting the needs of dense layout and convenient operation of wiring modules.
[0019] 2. The stacking of multiple tray modules enables high-density integration of modules, making the internal structure of the entire fiber optic patch panel more compact. Each tray module can be pulled out and operated independently without affecting the normal operation of other modules.
[0020] 3. The first elastic latch and the limiting block act as a stop to prevent the tray module from accidentally sliding out when not in use. In its natural state, the first elastic latch protrudes outward to form a mechanical locking structure with the limiting block in the guide rail groove, thus preventing the tray module from being pulled out. When the tray is pulled out to its maximum safe travel (extended position), the second elastic latch and the limiting block act as a stop to prevent the tray from detaching from the wiring box module. In specific situations where it is necessary to remove the entire tray module, the tray can be pulled out to the extended position first, then the second elastic latch can be pressed, and then the entire tray module can be completely removed.

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 Figures 1 to 8 As shown, a fiber optic patch panel with a tray includes:
[0034] The wiring box module 100 has guide rail seats 110 on both sides, and each guide rail seat 110 has at least one guide rail groove 111.
[0035] At least one tray module 200, the tray module 200 includes a tray plate 210 and two side slide bars 220, the two side slide bars 220 are respectively fixed to both sides of the tray plate 210, and the two side slide bars 220 are slidably connected to the guide rail grooves 111 of the two guide rail seats 110, so that the tray plate 210 is slidably connected to the wiring box module 100.
[0036] The internal height of the patch panel module 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. Figure 7 , Figure 9 , Figure 10 As shown in the example, the height of the wiring box module 100 can be 1U / 2U / 3U / 4U.
[0037] like Figures 1 to 8As shown, the interior of the patch panel module 100 can accommodate fiber optic wiring modules (fiber optic adapters). The guide rail 110 serves as a support and guide structure, guiding the tray module 200 to slide in the front-to-back direction. In the tray module 200, the tray 210 directly supports the fiber optic wiring modules (fiber optic adapters). The tray 210 can be slidably connected to the patch panel module 100 via two side slide bars 220, thus forming a drawer-type structure, meaning the tray 210 can be pulled out or pushed into the patch panel module 100.
[0038] When a user needs to operate the module on tray 210, the tray module 200 can be pulled outwards to expose the module on tray 210, thus greatly reducing the difficulty of operation. After the operation is completed, the tray module 200 can be pushed back into the wiring box.
[0039] The wiring box module 100 can support high-density integrated assembly of fiber optic wiring modules through the various tray modules 200 inside, and the tray modules 200 can be pulled out to easily operate the corresponding fiber optic wiring modules, thus simultaneously meeting the needs of dense arrangement and convenient operation of wiring modules.
[0040] like Figures 1 to 7 As shown, based on the above implementation method, there are multiple tray modules 200, and each tray module 200 is arranged sequentially along the height or width direction of the wiring box module 100. The number of guide rail grooves 111 on the guide rail base 110 is consistent with the number of tray modules 200 and is set one-to-one.
[0041] Multiple tray modules 200 are stacked, which enables high-density integrated arrangement of modules, making the internal structure of the entire fiber optic patch panel more compact. Each tray module 200 can be pulled out and operated independently without affecting the normal operation of other modules.
[0042] like Figures 1 to 4 As shown, based on the above embodiment, the guide rail groove 111 is provided with a limit stop 112, the side slide bar 220 is provided with a first elastic buckle 221, the sliding stroke position of the tray 210 includes a retracted position, when the tray 210 is in the retracted position, the first elastic buckle 221 abuts against the limit stop 112 and restricts the tray 210 from extending, the first elastic buckle 221 can separate from the limit stop 112 through elastic deformation to allow the tray 210 to extend.
[0043] The first elastic buckle 221 and the limiting block 112 serve to limit and stop the tray module 200 from accidentally sliding out when not in operation. In its natural state, the first elastic buckle 221 protrudes outward to form a mechanical locking structure with the limiting block 112 in the guide rail groove 111, thereby preventing the tray module 200 from being pulled out.
[0044] In the example, when the tray 210 is fully pushed into the wiring box module 100, the first elastic latch 221 is pressed inward by the limiting block 112, causing the first elastic latch 221 to pass over the limiting block 112. When it is necessary to remove the tray 210, the first elastic latch 221 can be pressed to separate the first elastic latch 221 from the limiting block 112, thereby allowing the tray 210 to slide freely.
[0045] Based on the above embodiments, the side slide bar 220 is also provided with a second elastic buckle 222. The sliding stroke position of the tray 210 also includes an extended position. When the tray 210 is in the extended position, the second elastic buckle 222 abuts against the limiting block 112 to restrict the tray 210 from leaving the wiring box module 100. The second elastic buckle 222 can separate from the limiting block 112 through elastic deformation to allow the tray 210 to cross the extended position and separate from the wiring box module 100.
[0046] When the tray 210 is pulled out to its maximum safe travel (extended position), the second elastic latch 222 and the limit stop 112 act as a limit stop to prevent the tray from detaching from the wiring box module 100. In specific situations where the entire tray module 200 needs to be removed, the tray 210 can be pulled out to the extended position first, then the second elastic latch 222 can be pressed, and then the entire tray module 200 can be completely removed. This detachable but actively unlocked mechanism ensures both the safety of the tray module 200's extension and retraction while maintaining flexibility.
[0047] Based on the above embodiments, the tray 210 is provided with a snap-fit structure 211 for snapping the power supply module.
[0048] The fiber optic wiring module can be snapped onto the tray 210 via the snap-fit structure 211, facilitating quick deployment or disassembly.
[0049] like Figure 1 , Figures 5 to 8 As shown, based on the above-described embodiment, the front side of the wiring box module 100 is provided with a front opening 120, and the tray 210 extends out or retracts into the wiring box module 100 through the front opening 120.
[0050] The front opening 120 of the wiring box module 100 is used for the tray module 200 to enter and exit, and is a channel for the tray module 200 to extend and retract.
[0051] Based on the above embodiments, a front baffle 300 is also included. The front baffle 300 is hinged to the front side of the wiring box module 100. The front baffle 300 can be rotated to an open state or a closed state. When the front baffle 300 is in the open state, the front opening 120 is exposed. When the front baffle 300 is in the closed state, the front opening 120 is closed.
[0052] This design incorporates a front baffle 300 opening and closing mechanism. Normally, the front baffle 300 can be used to shield against dust entry or accidental contact. When operation is required, the front baffle 300 can be opened, and the tray module 200 can be pulled out.
[0053] Based on the above embodiments, the wiring box module 100 is provided with two hinges 400. The two sides of the front baffle 300 are hinged to the wiring box module 100 through the two hinges 400. The hinge 400 includes a flexible part 410, a first rigid part 420 and a second rigid part 430. The first rigid part 420 and the second rigid part 430 are respectively located at both ends of the flexible part 410. The first rigid part 420 and the second rigid part 430 are respectively provided with a first connecting hole 421 and a second connecting hole 431. The wiring box module 100 is provided with a first plug 130 and the front baffle 300 is provided with a second plug 310. The first plug 130 is inserted into the first connecting hole 421 so that the hinge 400 is detachably connected to the wiring box module 100. The second plug 310 is inserted into the second connecting hole 431 so that the hinge 400 is detachably connected to the front baffle 300.
[0054] The hinge 400 achieves quick connection with the wiring box module 100 and the front baffle 300 through a plug and connecting hole. Among them, the flexible part 410 is responsible for enabling the rotation function of the hinge 400, the first rigid part 420 is plugged into the first plug 130 of the wiring box module 100, and the second rigid part 430 is plugged into the second plug 310 of the front baffle 300.
[0055] The hinge 400 with this strip structure is connected to the wiring box module 100 and the front baffle 300 through a plug-in structure. It does not need to be connected to the wiring box module 100 and the front baffle 300 with screws, so it occupies little space and does not affect the sliding and telescopic functions of the tray module 200.
[0056] Based on the above embodiments, the wiring box module 100 is further provided with one of a locking seat 140 and a locking block 320, and the front baffle 300 is provided with the other of a locking seat 140 and a locking block 320. When the front baffle 300 is in the closed state, the locking block 320 and the locking seat 140 engage to restrict the rotation of the front baffle 300.
[0057] The locking structure formed by the locking seat 140 and the locking block 320 can effectively prevent the front baffle 300 from opening by itself due to external force or vibration. In the specific structure, the locking seat 140 has a C-shaped notch, and the locking block 320 is a rod-shaped structure. The rod-shaped structure can be embedded in the C-shaped notch to achieve mechanical locking, thereby locking the front baffle 300 in the closed state.
[0058] Based on the above embodiment, one of the locking seat 140 and the locking block 320 is provided with a third connecting hole 141, and the wiring box module 100 is also provided with a third plug 150, which is plugged into the third connecting hole 141. This allows one of the locking seat 140 and the locking block 320 to be detachably connected to the wiring box module 100.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] 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.
