Description

Technical Field

[0001] This utility model belongs to the field of fiber optic splitters, and more specifically, it relates to a box-type fiber optic splitter. Background Technology

[0002] A box-type fiber optic splitter is a passive optical device used in fiber optic communication networks. Its core function is to distribute the input optical signal to multiple output ports in a specific ratio, achieving uniform or non-uniform distribution of optical power. Employing a compact box-type package design, it features small size, low insertion loss, high splitting accuracy, and strong environmental stability. It is widely used in FTTH, PON, and other scenarios and is one of the key components of optical distribution networks.

[0003] Traditional box-type fiber optic splitters lack convenient maintenance features. Their covers are usually secured to the box with four or more screws. During maintenance, the screws need to be disassembled and reassembled, which is cumbersome. Furthermore, the screws are prone to being lost, which can significantly hinder maintenance work.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a box-type fiber optic splitter in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a box-type fiber optic splitter, which solves the problem of the cumbersome operation of disassembling and assembling screws during current maintenance.

[0006] The purpose and effect of this utility model's box-type fiber optic splitter are achieved through the following specific technical means:

[0007] A box-type fiber optic splitter includes a protective housing, a convenient maintenance mechanism on the protective housing, and a protective mechanism on the front of the protective housing;

[0008] The convenient maintenance mechanism includes a hidden inner box, which is fixedly installed on the side of the inner wall of the protective box. A first elastic element is fixedly installed at the bottom of the inner wall of the hidden inner box, and a sliding strip is fixedly installed at the top of the first elastic element. The sliding strip is slidably connected to the inner wall of the hidden inner box, and a rotating shaft is rotatably connected to the top of the sliding strip. A pressure strip is fixedly installed at the top of the rotating shaft, and the pressure strip is movably connected to the inner cavity of the hidden inner box.

[0009] Furthermore, both the sliding strip and the clamping strip have through holes at their tops, and a pull ring is fixedly installed on the top of the clamping strip.

[0010] Furthermore, the convenient maintenance mechanism also includes a fixed shaft, which is fixedly installed on the back of the protective box. A rotating sleeve is rotatably connected to the outer wall of the fixed shaft, and a cover plate is fixedly installed on the outer wall of the rotating sleeve. The cover plate is movably abutted against the top of the protective box, and a through groove is provided on the top of the cover plate.

[0011] Furthermore, mounting ears are fixedly installed on both sides of the protective box, and a branch connector is fixedly installed on the front of the protective box.

[0012] Furthermore, the protective mechanism includes a fixed side plate, which is fixedly installed on the front of the protective box. A second elastic element is fixedly installed on the side of the fixed side plate. A connector is fixedly installed at the end of the second elastic element away from the fixed side plate. A sliding rod is slidably connected to the inner wall of the connector, and the end of the sliding rod is fixedly connected to the outer wall of the fixed side plate.

[0013] Furthermore, a splicing cylinder is fixedly installed on the inner wall of the connector, and a splicing cover is fixedly installed at the end of the splicing cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Thanks to the convenient maintenance mechanism, after the cover is closed on the top of the protective box, the user can pull the retaining strip from the pull ring to move it to the top of the cover. Then, the retaining strip can be rotated 90° to lock it in place on the top of the cover using the elastic force of the first elastic element. To disassemble, simply rotate the retaining strip back to the inner cavity of the hidden inner box using the elastic force of the first elastic element. The process does not require disassembling or assembling screws, improving the overall efficiency of maintenance and avoiding the problem of lost screws, thus facilitating smooth maintenance.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a box-type fiber optic splitter, including a protective box 1, a convenient maintenance mechanism 2 on the protective box 1, and a protective mechanism 3 on the front of the protective box 1.

[0028] The convenient maintenance mechanism 2 includes a hidden inner box 25, which is fixedly installed on the side of the inner wall of the protective box 1. A first elastic element 251 is fixedly installed at the bottom of the inner wall of the hidden inner box 25, and a sliding strip 252 is fixedly installed at the top of the first elastic element 251. The sliding strip 252 is slidably connected to the inner wall of the hidden inner box 25, and a rotating shaft 253 is rotatably connected to the top of the sliding strip 252. A pressure strip 254 is fixedly installed at the top of the rotating shaft 253 and is movably connected to the inner cavity of the hidden inner box 25. After the cover 23 is closed on the top of the protective box 1, the user can pull the pressure strip 254 to activate it. 54 is moved to the top of the cover plate 23, and then the clamping strip 254 is rotated 90° and released, so that the clamping strip 254 is fixed to the top of the cover plate 23 by the elastic force of the first elastic element 251, and is positioned. When disassembling, the clamping strip 254 is reset and rotated, and the clamping strip 254 is pulled back into the inner cavity of the hidden inner box 25 by the elastic force of the first elastic element 251. The process does not require disassembling and assembling the screws, which improves the overall efficiency of maintenance work and avoids the problem of losing screws, making maintenance work easier. The rotating shaft 253 and the sliding strip 252 are rotatably connected, which facilitates the rotation operation of the clamping strip 254.

[0029] Both the sliding strip 252 and the clamping strip 254 have through holes 255 at their tops. The clamping strip 254 has a pull ring 256 fixedly installed at its top. The through holes 255 facilitate the passage of air in the inner cavity of the hidden box 25 when the sliding strip 252 and the clamping strip 254 move up and down, thus improving the smoothness of their movement. The pull ring 256 makes it easy for the user to pull the clamping strip 254.

[0030] The convenient maintenance mechanism 2 also includes a fixed shaft 21, which is fixedly installed on the back of the protective box 1. A rotating sleeve 22 is rotatably connected to the outer wall of the fixed shaft 21. A cover plate 23 is fixedly installed on the outer wall of the rotating sleeve 22. The cover plate 23 is movably abutted against the top of the protective box 1. A through groove 24 is provided on the top of the cover plate 23. Through the design of the fixed shaft 21 and the rotating sleeve 22, the cover plate 23 is rotatably connected to the top of the protective box 1, avoiding the problem of the cover plate 23 falling off easily when it is removed for maintenance. The position of the through groove 24 corresponds to the top of the hidden inner box 25. Through the design of the through groove 24, the overall use of the hidden inner box 25 is facilitated.

[0031] The protective box 1 has mounting ears 11 fixedly installed on both sides, and a branch connector 12 fixedly installed on the front of the protective box 1. With the design of the mounting ears 11, the user can use screws to fix the structure to a certain place. The number of branch connectors 12 is designed during production according to the usage environment, and the number of branch connectors 12 corresponds to the number of protective mechanisms 3.

[0032] The protective mechanism 3 includes a fixed side plate 31, which is fixedly installed on the front of the protective box 1. A second elastic element 32 is fixedly installed on the side of the fixed side plate 31. A connector 33 is fixedly installed at the end of the second elastic element 32 away from the fixed side plate 31. A sliding rod 34 is slidably connected to the inner wall of the connector 33. The end of the sliding rod 34 is fixedly connected to the outer wall of the fixed side plate 31. Moving the connector 33 toward the fixed side plate 31 can compress the second elastic element 32. After releasing the connector 33, the elastic force of the second elastic element 32 can drive the connector 33 to reset. The sliding rod 34 is used to limit the horizontal movement of the connector 33.

[0033] The connector 33 has a splicing cylinder 35 fixedly installed on its inner wall, and a splicing cover 36 fixedly installed at the end of the splicing cylinder 35. In the initial state, the position of the connector 33 is maintained by the elastic force of the second elastic element 32. At this time, the splicing cylinder 35 and the splicing cover 36 can be spliced ​​on the outside of the branch connector 12 to achieve the function of protecting the branch connector 12. When in use, the connector 33 is pulled towards the fixed side plate 31 to open the splicing cylinder 35 and the splicing cover 36. Then the connector can be inserted into the branch connector 12 for use.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In use, pull the connector 33 toward the fixed side plate 31 to open the splicing cylinder 35 and the splicing cover 36. Then, the connector can be plugged into the branch connector 12 for use. After closing the cover plate 23 on the top of the protective box 1, the user can pull the clamping strip 254 to move it to the top of the cover plate 23. Then, rotate the clamping strip 254 90° and release it, so that the clamping strip 254 is fixed to the top of the cover plate 23 by the elastic force of the first elastic element 251 for positioning. If the cover plate 23 needs to be opened for maintenance, reset and rotate the clamping strip 254. Then, by the elastic force of the first elastic element 251, pull the clamping strip 254 back into the inner cavity of the hidden inner box 25. After that, the cover plate 23 can be rotated to open.
