[0024] In the specific implementation process, Figure 1-Figure 6 As shown, a positioning structure for an optical port of an optical module includes a module body 1 and a fixing frame 2 arranged on one side of the module body 1, a partition 9 is arranged inside the fixing frame 2, and positioning components are arranged on opposite sides of the partition 9, and a plurality of fixing bolts 4 are arranged on the fixing frame 2, and the fixing frame 2 is connected to one end of the module body 1 located at two connecting ports 7 through the plurality of fixing bolts 4;
[0025] The positioning assembly includes a movable plate 3, two movable plates 3 are provided, and the two movable plates 3 are arranged opposite to each other. The opposite sides of the two movable plates 3 in the vertical direction are movably connected to the inner side wall of the fixed frame 2 through the connecting column 11. The edges of the adjacent sides of the two movable plates 3 are arranged in an arc shape. One side of the two movable plates 3 is fixedly connected with a reset group for resetting the positions of the two movable plates 3.
[0026] The reset group includes a sliding block 12, a spring 8 and a limit plate 10. The upper end of the sliding block 12 is fixedly connected to the bottom end of the movable plate 3. An arc-shaped sliding groove is provided on the inner wall of the fixed frame 2. One side of the sliding block 12 is fixedly connected to one end of the spring 8. The end of the spring 8 away from the sliding block 12 is fixedly connected to the inner wall of the sliding groove. Two limit plates 10 are provided. The opposite sides of the two limit plates 10 are respectively fixedly connected to the opposite inner walls of the sliding groove. The opposite sides of the sliding block 12 are respectively movably connected to the two limit plates 10.
[0027] In the specific use process, when the external cable continuously moves toward the inside of the fixed frame 2, the two movable plates 3 are pushed in opposite directions. In this process, the two springs 8 are squeezed respectively by the sliding blocks 12 provided at the bottom of the two movable plates 3. Through the pushing force of the two springs 8, one side of the two movable plates 3 can be fitted with the external cable.
