Fusion fiber optic connector

Abstract

The invention relates to a welding type fiber connector. The fiber connector comprises a ceramic pin assembly and a tail assembly, wherein the tail assembly can be passed through by an on-site optical fiber. A preset short optical fiber is arranged in the ceramic pin assembly and fusion is carried on the short optical fiber and a core wire of the on-site optical fiber, wherein the core wire passes through the tail assembly; a reinforced protective sleeved pipe is arranged at the fusion connection portion; and one end of the protective sleeved pipe is connected with the ceramic pin assembly. Advantages of the fiber connector are as follows: fusion is carried on a short optical fiber and a core wire of an on-site optical fiber, wherein the core wire passes through a tail assembly; it is notneeded to arrange a cold conjunction alignment precision mechanism in the connector, thereby simplifying the manufacturing technology; one end of a protective sleeved pipe is connected with a ceramicpin assembly, so that an overlapping amount between the end of the protective sleeved pipe and a cladding portion of the core wire of the fiber can be reduced; the protective sleeved pipe penetrates a centre bore of a spring, thereby shortening an occupied length of the protective sleeved pipe; a spring and an inner sleeve are installed in the tail assembly, thereby simplifying an on-site operation; and one end of the protective sleeved pipe is connected with the ceramic pin assembly and thus the protective sleeved pipe and the ceramic pin assembly can retreat synchronizedly, so that winding loss or damage of a short optical fiber can be avoided and thus the quality of the connector is reliable.

Description

technical field [0001] The invention relates to a fusion-splicing optical fiber connector, which belongs to the technical field of optical fiber connection. Background technique [0002] With the continuous development of optical fiber communication technology, optical fiber wiring is widely used. In the case of local optical fiber wiring, etc., it is necessary to install optical fiber connectors on the optical fiber cables on site. At present, the field connectors made by cold connection have extremely high requirements on the manufacturing process, so that there are great problems in the quality, efficiency, pass rate and life of cold connection when they are applied in batches, especially the connection success rate and performance. Compared with welding, there are still great shortcomings. Welding solves the problems of cold splicing, improves the quality of splicing, and ensures the life of splicing. With the advent of FTTH small fusion splicing machines, field connect...

Problems solved by technology

Welding solves the problems of cold splicing, improves the quality of splicing, and ensures the life of splicing. With the advent of FTTH small fusion splicing machines, field connectors made by welding appear. However, in the prior art, ceramic pins are all It adopts the method of loading the inner sleeve from the back to the front. The connectors are too scattered or the external dimensions are large, resulting in complex operation, low efficiency, and prone to failure during the installation process, which limits its application range and application scale.
