Description

Technical Field

[0001] This utility model belongs to the field of optical splitter technology, specifically relating to an optical splitter with a dustproof structure. Background Technology

[0002] An optical splitter, also known as a fiber optic splitter, is one of the important passive devices in an optical fiber link. It is an optical fiber aggregation device with multiple input and multiple output ports. Existing optical splitters generally include a housing, a cover plate on the housing, and an optical splitter assembly. The housing is also equipped with input ports and output ports. The input ports are connected to the input ports of the optical splitter assembly through optical fibers, and the output ports are connected to the output ports of the optical splitter assembly through optical fibers.

[0003] Currently, optical splitters generate a certain amount of heat during operation. Therefore, heat dissipation holes are usually installed on the outside of the optical splitter housing, and dust filters are installed at the heat dissipation holes to allow dust to pass through the heat dissipation holes and enter the optical splitter.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN221485671U discloses "a dustproof optical splitter", which includes a box body and a box cover.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5 The present invention provides the following technical solution: an optical splitter with a dustproof structure, comprising an optical splitter body 1, wherein the optical splitter body 1 includes a bottom shell 11, a top cover 12 fixed to the top of the bottom shell 11, a plurality of adapters 13 equally spaced and installed at the front end of the bottom shell 11, and a splitter 14 fixed inside the bottom shell 11. The adapters 13 are connected to the splitter 14 by means of optical fiber 15. A plurality of mounting ports 111 are processed at the front end of the bottom shell 11, and the adapters 13 are installed in the mounting ports 111. The invention also includes a clamping mechanism 2, which is used to press the adapters 13 into the mounting ports 111. The clamping mechanism 2 includes: an inverted L-shaped fixing plate 21, a pressure plate 22, a pull rod 23, and a return spring 24.

[0037] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the inverted L-shaped fixing plate 21 is fixed to the top of the top cover 12, the pressure plate 22 is located below the horizontal part of the inverted L-shaped fixing plate 21 and corresponds to the mounting port 111, and a through hole 121 for the pressure plate 22 to pass through is machined on the top cover 12. The pull rod 23 is fixed to the top of the pressure plate 22 and passes through the horizontal part of the inverted L-shaped fixing plate 21. The reset spring 24 is sleeved on the pull rod 23 and is located between the horizontal part of the inverted L-shaped fixing plate 21 and the pressure plate 22. After adopting the above scheme, in use, the beam splitter 14 is fixed to the bottom shell 11 with screws, and then the adapter 13 is connected to the beam splitter 14 with optical fiber 15, and the optical fiber 15 passes through the corresponding mounting port 111. Finally, the top cover 12 is fixed to the top of the bottom shell 11 with screws. Pull the lever 23 upward to move the pressure plate 22 upward. At this time, the return spring 24 is in a contracted state. After the installation port 111 is fully exposed, insert the adapter 13 into the installation port 111. Then release the lever 23. The pressure plate 22 moves downward under its own weight and the elastic force of the return spring 24, and presses the adapter 13, thus achieving stable installation of the adapter 13. This utility model uses the clamping mechanism 2 to flexibly press the adapter 13. Under the premise of ensuring the stable installation of the adapter 13, the adapter 13 can be pulled out by pulling the pressure plate 22 upward. After separating the adapter 13 from the optical fiber 15, it can be repaired or replaced without disassembling the top cover 12, which is more convenient and will not affect other adapters 13, making it safer.

[0038] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the clamping mechanism 2 further includes a pull ring 25, which is fixed to the top of the pull rod 23. With the above solution, the pull rod 23 can be easily moved by the pull ring 25 during use.

[0039] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the clamping mechanism 2 further includes: guide posts 26. Two guide posts 26 are symmetrically fixed to the top of the pressure plate 22, and the guide posts 26 penetrate the horizontal part of the inverted L-shaped fixing plate 21. After adopting the above scheme, when in use, the two guide posts 26 are used to guide the pressure plate 22, which further improves the stability of the pressure plate 22.

[0040] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the width of the adapter 13 is equal to the width of the mounting port 111. With the above solution, when the adapter 13 is inserted into the mounting port 111 during use, the outer wall of the adapter 13 fits against the inner wall of the mounting port 111. This close fit gives the adapter 13 high stability and prevents the adapter 13 from sliding or shaking laterally.

[0041] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, this embodiment also includes: a positioning piece 131, which is fixed to the top surface of the adapter 13. A positioning groove 221 for the positioning piece 131 to be embedded is processed at the bottom end of the pressure plate 22. With the above solution, when the adapter 13 is pressed by the pressure plate 22 during use, the positioning piece 131 is embedded in the positioning groove 221, which further locks the adapter 13, improves the stability of the adapter 13, and prevents the adapter 13 from slipping unexpectedly due to external force.

[0042] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, a chamfer 222 is machined at the port of the positioning groove 221. With the above solution, the chamfer 222 has a guiding function when in use, which makes it easy for the positioning piece 131 to be embedded in the positioning groove 221.

[0043] Preferably, by Figure 1 As shown, this embodiment also includes a dustproof net 3. Heat dissipation windows 112 are processed on both the left and right sides of the bottom shell 11. The dustproof net 3 is fixed to the outer wall of the bottom shell 11 with bolts to block the heat dissipation windows 112. After adopting the above solution, the design of the heat dissipation window 112 helps to assist in the heat dissipation of the optical splitter during use. The dustproof net 3 can effectively prevent external dust from entering the inner side of the optical splitter body 1 through the heat dissipation window 112.

[0044] Preferably, by Figure 1 and Figure 5 As shown, in this embodiment, it also includes an auxiliary support block 4. The auxiliary support block 4 is a rubber block and is glued and fixed inside the bottom shell 11 at the position corresponding to the mounting port 111. The top surface of the auxiliary support block 4 is higher than the inner bottom surface of the mounting port 111. After adopting the above solution, when in use, the auxiliary support block 4 assists in supporting the adapter 13, which improves the support surface and further improves the stability of the adapter 13 installation.

[0045] In addition, because the auxiliary support block 4 is a rubber block and the top surface of the auxiliary support block 4 is higher than the inner bottom surface of the mounting port 111, it can provide flexible support for the adapter 13 and has a certain buffer and shock absorption function. After the auxiliary support block 4 is retracted, it also has a certain anti-slip effect, which further improves the stability of the adapter 13 installation.

Finally, the top cover 12 is fixed to the top of the bottom shell 11 with screws.

[0049] Then pull the lever 23 upward to move the pressure plate 22 upward. At this time, the return spring 24 is in a contracted state. After the mounting port 111 is fully exposed, insert the adapter 13 into the mounting port 111. Then release the lever 23. The pressure plate 22 moves downward under its own weight and the elastic force of the return spring 24 and presses the adapter 13, thus achieving stable installation of the adapter 13.

[0050] This utility model uses a clamping mechanism 2 to flexibly press the adapter 13. Under the premise of ensuring the stable installation of the adapter 13, the adapter 13 can be pulled out by pulling the pressure plate 22 upward. After the adapter 13 is separated from the optical fiber 15, it can be repaired or replaced without disassembling the top cover 12, which is more convenient and will not affect other adapters 13, making it safer.

[0051] In this utility model, after the pressure plate 22 presses the adapter 13, the positioning piece 131 is embedded in the positioning groove 221, which further locks the adapter 13, improves the stability of the adapter 13, and prevents the adapter 13 from slipping unexpectedly due to external force.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
