Embodiment Construction
[0020] Refer to attached picture. An optical module structure described in this embodiment includes an upper cover 5 , a bottom case 4 , an MPO adapter 3 , an MT ferrule 2 and a clamping piece 1 .
[0021] One end of the MPO adapter 3 is provided with a buckle 31 for connecting to the MPO connector 6 ; the inner end is provided with a mounting groove 32 positioned with the MT ferrule 2 . The front part of the MT ferrule 2 is inserted into the installation groove 32 of the MPO adapter 3 and installed to the position where the step surface 21 of the MT ferrule coincides with the end face of the MPO installation groove.
[0022] The bottom case 4 is provided with a mounting groove 41 , and after the installation of the MT ferrule 2 and the MPO adapter 3 is completed, they are integrally installed in the mounting groove 41 of the bottom case. The rear end of the MT ferrule 2 is provided with a pin seat 7 as a sheet metal support, and the length dimension of the pin seat 7 is redu...
