[0027] See Figures 2 to 8 , an optical port fixing structure for an optical module of the present invention comprises:

[0028] The optical port adapter fixed housing 100 is mounted between the upper cover 200 and the base 300 of the optical module in cooperation with the optical port adapter fixed housing 100. The optical port adapter fixed housing 100 includes a plurality of optical port adapter mounting slots 101. Each optical port adapter mounting slot 101 is provided with a mounting bayonet 102 corresponding to the optical port adapter 400. The optical port adapter 400 is installed on the optical port adapter fixed housing 100 through the mounting bayonet 102. The optical port adapter 400 is provided with an optical port. The flange 401, the upper cover 200 and the base 300 are respectively provided with avoidance grooves 201 and avoidance grooves 301. The optical port adapter 400 is limited by its own optical port flange 401, the mounting bayonet 102, and the avoidance grooves 201 and 301. The optical port adapter 400 installed on the optical port adapter fixed housing has its front end extending out of the mounting bayonet 102 and its rear end extending into the optical port adapter mounting groove 101. The two ends of the optical port adapter 400 can be connected to optical fibers respectively.

[0029] Compared with the existing upper and lower buckling optical port adapter fixing method, this embodiment adopts an integrated structure without assembly gaps and has better electromagnetic shielding performance.

[0030] In one embodiment of the present invention, in order to further improve the convenience of installation and the reliability of positioning, an optical port flange slot 302 matching the optical port flange 401 is provided at the bottom of the base 300. During installation, the optical port flange 401 can be clamped in the optical port flange slot 302 to complete the positioning.

[0031] In one embodiment, a boss 303 is provided on the base 300, and a threaded hole 304 is provided on the boss 303.

The boss 303 is located in the middle of the optical port side of the base 300, and the four optical port adapters 400 are separated in pairs on the left and right sides of the boss 303. After the optical port adapter 400 is inserted into the mounting bayonet hole 102, the optical port flange 401 is set in the optical port flange slot 302 of the base. The bolts pass through the countersunk holes provided on the boss 303 and are locked with the threaded holes on the base. The base is connected to the upper cover through the assembly threaded holes and the threaded holes. It is not only simple and reliable in structure, but also quick and convenient to assemble, and has good electromagnetic shielding and mass production feasibility.
