Problems solved by technology

However, there are problems in this method: 1. There is a gap between the MT ferrule and the positioning groove, and the MPO connector is difficult to stabilize
2. The MT ferrule and the MPO adapter are positioned and assembled separately, which makes the positioning references of the MPO connector and the MT ferrule different, increasing the positioning error of the optical end face

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...

Abstract

The present invention provides a high-tolerance fixing structure of an MT insertion core in an optical module structure, the MT insertion core and the MPO adapter are firstly installed in a matched mode, then the MPO adapter and the MT insertion core are integrally installed on the bottom shell, the clamping piece made of the conductive plastic material is clamped between the MT insertion core and the bottom shell, and then other structural parts are installed. The size control is simple, the optical end face positioning error of the MPO connector and the MT insertion core is reduced, and the electromagnetic shielding performance can be enhanced.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication components, in particular to a method and structure for assembling and fixing an MT ferrule in an optical module structure. Background technique [0002] Optical modules need to be connected to optical cables during testing or practical application. There are optical cable connectors on the optical cables to connect to the corresponding adapters on the optical modules. The more common connectors are LC, SC, FC, MPO and other types. [0003] Among them, MPO connectors are widely used in optical modules packaged in SFP+ and QSFP due to their small size, high precision and high connection density. However, due to the small size and high precision of the MPO connector, the corresponding MT ferrule on the optical module needs to have high installation precision to ensure that the optical power is normal after connection. [0004] When the MPO connector is inserted into the optical ...
