It is an important component in optical fiber communication systems. Through its guiding effect, the transmission quality and efficiency of optical signals are guaranteed. The design and manufacture of optical fiber waveguides require that their inner walls be very smooth to reduce the loss of optical signals during transmission. At the same time, their structures and materials also need to have sufficient stability to adapt to various usage environments.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-6, Plum blossom-shaped optical fiber waveguide, including a waveguide body 1. A cylindrical cavity 13 is vertically and penetratingly opened in the middle of the waveguide body 1. A limiting rod 4 is vertically inserted into the cylindrical cavity 13. A plurality of circular holes 12 are evenly opened on the outer side of the waveguide body 1 where the cylindrical cavity 13 is located. A fixing piece 5 is horizontally installed on the upper surface of the waveguide body 1. A fixing bolt 6 is installed in the middle of the fixing piece 5. A limiting wall 131 is provided at the top of the cylindrical cavity 13 of the waveguide body 1. The limiting wall 131 inclines 2° towards the inner side of the cylindrical cavity 13. The top of the limiting rod 4 abuts against the bottom of the limiting wall 131. The limiting rod 4 can abut against the inside of the cylindrical cavity 13, thereby separating the channels of each circular hole 12.

[0024] Moreover, positioning columns 11 are provided on the upper surface of the waveguide body 1. Threaded portions 14 are opened on the outer wall of the waveguide body 1. A lower fixing member 2 and an upper fixing member 3 are respectively screwed on the waveguide body 1 at the threaded portions 14. The structures of the upper fixing member 3 and the lower fixing member 2 are the same. The upper fixing member 3 and the lower fixing member 2 facilitate the installation of the waveguide body 1.

[0025] In addition, a first bolt hole 31 is opened in the middle of the upper fixing member 3. The first bolt hole 31 meshes with the threaded portion 14. Clamping grooves 32 are symmetrically opened on both side walls of the upper fixing member 3. The clamping grooves 32 are convenient for using a wrench to rotate.

[0026] Moreover, a through hole 51 is opened in the middle of the fixing piece 5. The fixing bolt 6 can pass through the through hole 51. A plurality of openings 52 are opened on the outer side of the fixing piece 5 where the through hole 51 is located. A positioning hole 53 is opened on one side of the fixing piece 5 where the opening 52 is located. The diameter of the positioning hole 53 is the same as the diameter of the positioning column 11. The positioning hole 53 and the positioning column 11 are coaxial. The cooperation of the positioning hole 53 and the positioning column 11 can ensure the accurate installation position and also ensure that the positioning fixing piece 5 will not rotate easily.

[0027] And, a second bolt hole 41 is opened in the middle of the top surface of the limiting rod 4. The fixing bolt 6 can be screwed into the second bolt hole 41. The fixing bolt 6 and the second bolt hole 41 are coaxial. The fixing bolt 6 can fix the limiting rod 4 to prevent it from falling.

[0028] In this embodiment, when assembling the waveguide body 1, first align the surface of the limiting rod 4 with the second bolt hole 41 with the cylindrical cavity 13, and vertically insert it from the bottom surface of the waveguide body 1 without the positioning column 11. After inserting the limiting rod 4 into the cylindrical cavity 13, the top of the limiting rod 4 abuts against the limiting wall 131. Under the restriction of the limiting wall 131, the limiting rod 4 cannot move upward anymore. Then install the fixing piece 5 to ensure that the positioning column 11 is inserted into the positioning hole 53, and then the fixing bolt 6 can be installed.

[0029] Pass the fixing bolt 6 through the through hole 51, and then screw it into the second bolt hole 41 so that the limiting rod 4 will not fall downward, so that each round hole 12 can be separated. Such round holes 12 and the cylindrical cavity 13 form a plum blossom shape, so that the optical fiber can pass through multiple channels. Then, install the fixing member 3 and the lower fixing member 2 on the bolt portion 14, which facilitates the installation of the waveguide body 1 onto other components.

[0030] In the present utility model, by providing round holes 12 and a cylindrical cavity 13 in a plum blossom shape on the waveguide body 1, after installing the limiting rod 4 and connecting the limiting rod 4 with the fixing bolt 6, the limiting rod 4 cannot fall, so that each round hole 12 can be separated. In this way, the original single channel becomes the current multi-channel, and the optical fiber can be dispersed in the channels of each round hole 12.

[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
