Combined optical fiber connector

Abstract

The invention discloses a combined optical fiber connector which comprises an insertion core, an annular lantern ring and a fixing piece, a protrusion is arranged in the middle of the top face of the insertion core, the insertion core is provided with fixing holes around the protrusion, the lantern ring is provided with a fixing piece through hole, and an optical fiber and glue are polished to be flush with the outer side face of the insertion core at the protruding part of the outer side face of the insertion core. The sleeve ring can be sleeved on the protrusion in the middle of the insertion core, the fixing piece penetrates through the fixing piece through hole to be connected with the fixing hole so as to fix the sleeve ring on the insertion core, the thickness of the sleeve ring is larger than the height of the protrusion so as to enable the outer side face of the insertion core to form an optical fiber recess relative to the sleeve ring top face of the sleeve ring, and the sleeve ring top face of the sleeve ring is 2.5-5.0 micrometers higher than the outer side face of the insertion core. The beneficial effects of the technical scheme are that the ferrule is sleeved with the lantern ring, the lantern ring is larger than the height of the protrusion on the ferrule to form the optical fiber recess, compared with the optical fiber recess formed by polishing, the optical fiber recess is easy to control, the recess size is regular, and the phenomenon that the middle is low and the edge is high is avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a combined optical fiber connector. Background technique [0002] As the optical communication industry continues to advance, more and more optical fibers are used. However, fiber optic connectors are very sensitive to dust. For this reason, the non-contact fiber optic connector was invented by Suzhou Lightas Co., Ltd., which has superior performance and improved a number of technical indicators, such as improving the life of the fiber optic connector and improving the repeatability of plugging and unplugging. 10 times higher, anti-dust and anti-dirt, reduced insertion loss, improved return loss, and can be freely inter-plugged with the connector. However, the structure of this non-contact optical fiber connector is complex, and the depth of the optical fiber depression is too wide. It consists of two parts, one is the metal chip at the front end, and the other is the plas...

Problems solved by technology

[0004] In this optical fiber depression is formed by polishing, the polishing process is complicated, and the polished depression is not regular, its edge is shallow, and the middle part is deep

Such a polishing effect is not good
