Description
Technical Field
[0001] This utility model belongs to the field of optical fiber communication technology, and relates to a tray for optical fiber distribution frame and a termination module and tray integrated structure. 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 termination modules (i.e., fiber optic adapters). In some designs, the patch panel uses a tray structure to support the termination modules, improving the overall neatness and manageability of the layout. However, in practical applications, the module connection structure on the tray is not designed reasonably, resulting in a cumbersome assembly and disassembly process. Moreover, the rigid module connection structure of the tray limits the installation direction of the termination modules, making flexible deployment in limited spaces impossible. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a tray for fiber optic distribution frames and an integrated structure of termination modules and trays.
[0005] The objective of this utility model can be achieved through the following technical solution: a tray for fiber optic distribution frames, comprising:
[0006] A tray, wherein at least two sets of snap-fit modules are provided on the tray, and each set of snap-fit modules is evenly arranged along the width direction of the tray. Each snap-fit module includes a front stop block, a middle stop block and a rear stop block arranged sequentially along the front end to the rear end of the tray. The end of the front stop block has a beveled part and the end of the rear stop block has a bent part.
[0007] At least two sets of the snap-fit modules constitute a module fixing unit. In the module fixing unit, the front stop block constitutes a forward stop structure, the two middle stops located on both sides of the module fixing unit constitute a lateral stop structure, the two rear stops located on both sides of the module fixing unit constitute a rear stop structure, and the inclined part of the front stop block and the bent part of the rear stop block cooperate to form a vertical stop structure.
[0008] Preferably, the front stop includes a spring plate portion and a beveled portion portion, the spring plate portion being vertically disposed on the support plate, and the beveled portion portion being located at the end of the spring plate portion.
[0009] Preferably, the width of the beveled portion is greater than the width of the end of the spring piece portion.
[0010] Preferably, the protrusion height of the middle stop block and the rear stop block is lower than the protrusion height of the front stop block.
[0011] Preferably, side slides are provided on both sides of the tray.
[0012] Preferably, the pallet has several weight-reducing holes.
[0013] An integrated structure of termination module and tray includes the tray for fiber optic distribution frame and at least one termination module, which is detachably connected to the tray via a module fixing unit.
[0014] Preferably, elastic buckles are provided on both sides of the tail of the termination module. The front stop of the module fixing unit is in contact with the front end face of the termination module. The two middle stops on both sides of the module fixing unit are in contact with the two sides of the termination module, respectively. The two elastic buckles are in contact with the two rear stops on both sides of the module fixing unit, respectively. The inclined part of the front stop and the rear stop respectively fasten the front end of the termination module and the elastic buckles.
[0015] Preferably, the bottom surface of the termination module is provided with at least one clearance groove. The number of clearance grooves is the same as the number of snap-fit modules on the non-side sides of the module fixing unit and they are set one-to-one. The groove depth of the clearance groove is greater than or equal to the protrusion height of the rear stop block and the middle stop block. The middle stop block and the rear stop block in the snap-fit modules on the non-side sides of the module fixing unit are located in the clearance groove.
[0016] Preferably, one end of the clearance groove extends to the front end face of the termination module and forms a card interface, the front stop is embedded in the card interface, and the beveled part is engaged with the card interface.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. The module fixing unit allows the termination module to be deployed on the tray in more diverse installation directions, which significantly simplifies the disassembly and assembly steps and enables the termination module to be flexibly deployed in limited space.
[0019] 2. The snap-fit module adopts a standardized spacing layout, which, when combined with the clearance slot of the termination module, enables the tray to have stronger compatibility, allowing the same tray to flexibly adapt to a variety of termination modules with different widths (i.e. different core counts).
[0020] 3. The middle and rear stops located on the sides can be hidden within the clearance groove of the termination module, preventing the termination module from interfering with these middle and rear stops during sliding. The front stop is higher than the depth of the clearance groove, which means that after the termination module slides into place, the front stop can abut against the front end face of the termination module.

Detailed Implementation
[0031] 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.
[0032] like Figures 1 to 7B As shown, a tray for a fiber optic patch panel includes:
[0033] The tray 100 is provided with at least two sets of snap-fit modules 200. Each set of snap-fit modules 200 is evenly arranged along the width direction of the tray 100. Each snap-fit module 200 includes a front stop 210, a middle stop 220 and a rear stop 230 arranged sequentially from the front end to the rear end of the tray 100. The end of the front stop 210 has a beveled part 211 and the end of the rear stop 230 has a bent part 231.
[0034] At least two sets of snap-fit modules 200 constitute a module fixing unit 300. In the module fixing unit 300, the front stop 210 constitutes a forward stop structure, the two middle stops 220 located on both sides of the module fixing unit 300 constitute a lateral stop structure, and the two rear stops 230 located on both sides of the module fixing unit 300 constitute a rear stop structure. The inclined part 211 of the front stop 210 and the bent part 231 of the rear stop 230 work together to constitute a vertical stop structure.
[0035] The core of this tray design for fiber optic patch panels lies in its snap-fit module 200 structure (including front stop 210, middle stop 220 and rear stop 230), which is designed to provide an efficient and reliable fixing mechanism for termination modules 400 (such as fiber optic adapters, patch cord management modules, etc.). Each module fixing unit 300 can fix one termination module 400.
[0036] In simple terms, the forward stop function is achieved by the front stop block 210, which directly blocks the front of the termination module 400, restricting its forward sliding. The lateral stop function is achieved by the middle stops 220 on both sides of the module fixing unit 300, which restrict the left and right movement of the module. The rear stop function is achieved by the rear stops 230 on both sides of the module fixing unit 300, which abut against the termination module 400 to prevent it from shifting backward. The vertical stop function (Z-axis degree of freedom) is achieved by the inclined part 211 and the bending part 231 working together, which hold the termination module 400 in place and prevent it from being lifted. The inclined part 211 of the front stop block 210 acts as a guide ramp, allowing the front end of the termination module 400 to be pressed downward into the module fixing unit 300 and engaged with the inclined part 211.
[0037] The module fixing unit 300 described above enables the termination module 400 to have at least two mounting orientations, for example:
[0038] Method 1: The termination module 400 can be installed by pushing it in from back to front. First, the termination module 400 is placed flat on the support plate 100, so that the rear blocks 230 and the middle block 220 on both sides are located on both sides of the termination module 400, so they will not obstruct the termination module 400 from moving forward. When the termination module 400 moves forward to the predetermined position, the front block 210 abuts against the front end of the termination module 400, and the two elastic buckles 410 at the rear end of the termination module 400 are respectively engaged with the two rear blocks 230, and the inclined part 211 and the bent part 231 just fit into the termination module 400. This means that the termination module 400 can be inserted and installed from the rear end of the fiber optic distribution frame.
[0039] Method 2: The termination module 400 can be installed by snapping it in from front to back. First, move the termination module 400 to the top of the module fixing unit 300 from front to back. Then, place the rear end of the termination module 400 on the tray 100 and make the two elastic clips 410 at the rear end of the termination module 400 engage with the two rear stops 230 respectively. Next, press down on the front end of the termination module 400 so that the front end of the termination module 400 is engaged in place by the inclined surface 211 of the front stop 210. This means that the front end of the termination module 400 can be pulled out of the fiber optic patch panel first, and then the termination module 400 can be installed from the front or top of the tray.
[0040] The module fixing unit 300 allows the termination module 400 to be deployed on the tray 100 in more diverse installation orientations, significantly simplifying the disassembly and assembly steps and enabling the termination module 400 to be flexibly deployed in limited spaces. Option 1 is suitable for situations where there is ample operating space behind the rack, while Option 2 is suitable for situations where space behind the rack is limited or where quick replacement of a single module is required.
[0041] Based on the above embodiments, the front stop 210 includes a spring plate portion 212 and an inclined portion 211. The spring plate portion 212 is vertically disposed on the support plate 100, and the inclined portion 211 is located at the end of the spring plate portion 212.
[0042] The spring piece 212 has an elastic deformation function, which facilitates the insertion of the front end of the termination module 400. When the front end of the termination module 400 is pressed down, the inclined part 211 is subjected to force and the spring piece 212 undergoes elastic deformation, so that the front end of the termination module 400 can be engaged with the inclined part 211.
[0043] It is important to note that the snap-fit module 200 adopts a standardized spacing layout. When used in conjunction with the clearance slot 420 of the termination module 400, it enhances the compatibility of the tray 100, allowing the same tray 100 to flexibly accommodate various termination modules 400 with different widths (i.e., different numbers of pins), such as 8-pin, 12-pin, and 16-pin. For example, if the spacing between two adjacent snap-fit modules 200 is N, and the width of the termination module 400 is 2N (8 pins), then the module fixing unit 300 contains three sets of snap-fit modules 200, with the middle set located within the clearance slot 420. If the width of the termination module 400 is 3N (12 pins), then the module fixing unit 300 contains four sets of snap-fit modules 200, with two sets located within the clearance slot 420. This pattern continues, enabling the tray 100 to accept termination modules 400 of various specifications.
[0044] In summary, the pallet 100 only needs to be uniformly arranged with standard spacing snap-fit modules 200. There is no need to make separate molds or customize pallets for each size of the termination module 400. As long as the width of the termination module 400 is an integer multiple of N, it can be adapted by selecting an appropriate number of snap-fit modules 200.
[0045] Based on the above embodiment, the width of the inclined portion 211 is greater than the width of the end of the spring portion 212.
[0046] like Figure 5 As shown, based on the above embodiment, the protrusion heights of the middle stop 220 and the rear stop 230 are both lower than the protrusion height of the front stop 210. The middle stop 220 and the rear stop 230, located on the sides, can be hidden within the clearance groove 420 of the termination module 400, preventing the termination module 400 from interfering with these middle stop 220 and rear stop 230 during sliding. The front stop 210 is deeper than the clearance groove 420, meaning that after the termination module 400 slides into place, the front stop 210 can abut against the front end face of the termination module 400.
[0047] like Figure 1 , Figure 2 As shown, based on the above embodiment, side slides 110 are provided on both sides of the tray 100. The tray 100 can be slidably connected to the fiber optic distribution frame through the side slides 110, so that the tray 100 can be pulled out or pushed in.
[0048] Based on the above embodiment, the tray 100 is provided with a plurality of weight-reducing holes 120. The weight-reducing holes 120 can reduce the weight of the tray 100, thereby reducing the overall weight of the fiber optic patch panel.
[0049] like Figures 1 to 7BAs shown, a termination module and tray integrated structure includes a tray for a fiber optic distribution frame and at least one termination module 400, which is detachably connected to the tray 100 via a module fixing unit 300.
[0050] Based on the above implementation, elastic buckles 410 are provided on both sides of the tail of the termination module 400. The front stop 210 of the module fixing unit 300 is in contact with the front end face of the termination module 400. The two middle stops 220 located on both sides of the module fixing unit 300 are in contact with the two sides of the termination module 400 respectively. The two elastic buckles 410 are in contact with the two rear stops 230 located on both sides of the module fixing unit 300 respectively. The inclined part 211 of the front stop 210 and the rear stop 230 respectively fasten the front end of the termination module 400 and the elastic buckles 410.
[0051] The termination module 400 has elastic buckles 410 on both sides of its tail. Combined with the front stop 210, middle stop 220, and rear stop 230 in the module fixing unit 300, this forms a stable yet flexible installation mechanism. The front stop 210 directly prevents the termination module 400 from sliding forward, ensuring it will not shift when subjected to forward force. The two middle stops 220 located on both sides of the module fixing unit 300 restrict the lateral movement of the termination module 400. The elastic buckles 410 on both sides of the tail of the termination module 400 contact the rear stops 230 on both sides of the module fixing unit 300, achieving a stable locking effect through elastic deformation characteristics, preventing the termination module 400 from sliding backward or accidentally falling off. The beveled portion 211 of the front stop 210 and the bent portion 231 of the rear stop 230 together restrict the upward freedom of the termination module 400.
[0052] like Figure 1 , Figure 5 As shown, based on the above embodiment, the bottom surface of the termination module 400 is provided with at least one clearance groove 420. The number of clearance grooves 420 is the same as the number of snap-fit modules 200 on the non-side sides in the module fixing unit 300 and they are set one-to-one. The groove depth of the clearance groove 420 is greater than or equal to the protrusion height of the rear stop block 230 and the middle stop block 220. The middle stop block 220 and the rear stop block 230 in the snap-fit modules 200 on the non-side sides in the module fixing unit 300 are located in the clearance groove 420.
[0053] The positions and dimensions of these clearance slots 420 are precisely designed so that when the termination module 400 is slidably installed in place, the middle blocks 220 and rear blocks 230 (excluding the two sides) fall precisely into their corresponding clearance slots 420. During the process of pushing the termination module 400 from back to front, in addition to the middle blocks 220 and rear blocks 230 used for limiting movement on both sides, there may also be multiple locking modules 200 in the middle position. If the middle blocks 220 and rear blocks 230 on these modules are not designed to allow clearance, they will hinder the smooth sliding of the termination module 400. The clearance slots 420 allow these middle blocks 220 and rear blocks 230 in the middle position to be concealed within the slots, preventing them from contacting the bottom surface of the termination module 400 or generating resistance, thus achieving smooth sliding installation.
[0054] like Figures 1 to 4 , Figures 6A to 7B As shown, based on the above embodiment, one end of the clearance groove 420 extends to the front end face of the termination module 400 and forms a card interface 421. The front stop 210 is embedded in the card interface 421, and the beveled part 211 engages with the card interface 421. The beveled part 211 at the end of the front stop 210 engages with the edge of the card interface 421 in a snap-fit manner, thereby completing the vertical (Z-direction) locking.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] 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.
