Optical fiber connector and assembling method thereof

Abstract

The invention discloses an optical fiber connector which comprises a metal sleeve and a ceramic insertion core. A metal ring is arranged between the metal sleeve and the ceramic insertion core. The metal ring sleeves the ceramic insertion core and is arranged at the middle part of the ceramic insertion core. According to the optical fiber connector and the assembling method, through performing differentiated adjustment on the structure and using the transition metal ring, a mechanical matching force is used for fixing each assembly. In the assembling process, the end surfaces of the ceramic insertion core and the core wire are effectively protected from damage. Through the assembling method, similar products can be produced and furthermore high product performance and mechanical requirements can be satisfied. The optical fiber connector and the assembling method thereof have advantages of simple structure, relatively high efficiency, low cost, mass production of products, relatively low requirement for production process, and effective settlement of a problem of incapability of producing individual structures.

Description

technical field [0001] The invention relates to an optical fiber connector and an assembly method thereof. Background technique [0002] TOSA (Optical Transmitting Sub-module), ROSA (Optical Receiving Sub-module) and other Receptacle structures, as the most important devices in optical communication devices, with the development of technology, their structures are becoming more and more complex. Many structures used to be The methods are difficult to solve: due to its performance requirements, it is an important issue to protect the ceramic ferrule (Ferrule) and realize simple and convenient assembly. [0003] In optical communication products, the ceramic ferrule is matched with the metal sleeve, and the performance of the two end faces of the ground ceramic ferrule must be guaranteed. The assembly and grinding of the ceramic ferrule directly affect the communication performance. It is particularly important to effectively control the force of the ceramic ferrule and effec...

AI Technical Summary

Problems solved by technology

[0005] The use of glue has the following problems: when the metal sleeve is in use, it will be laser welded to other devices, and the high temperature at the moment of laser welding can directly evaporate the glue; during the assembly process of the product, the ceramic surface of the ferrule will be damaged, affecting The performance of the product; the use of the product under extreme conditions may cause the glue to fail

The use of forced mechanical press-fitting has the following problems: ceramic end faces and core wires are damaged, which affects product performance

[0006] To ensure the optical parameters and performance of the PC end of the optical fiber connector, the conventional press-in regrinding method has been unable to solve the problem
