A fiber optic connector

Abstract

The invention relates to an optical fiber connector. The optical fiber connector comprises a flange plate and a back sleeve, a guide structure is arranged on the flange plate or the back sleeve, a guide hole is formed in the guide structure, the front end of the guide hole is communicated with an inner hole of the flange plate, the rear end of the guide hole is communicated with an inner hole of the back sleeve, and the guide hole is in a taper shape with the aperture which is gradually reduced from the rear to the front. The guide structure is arranged on the flange plate or the back sleeve so that when glue injection or fiber penetration is performed, a gluing machine needle head or a wire core penetrates from the rear end of the back sleeve, the gluing machine needle head or the wire core can be gradually guided into the inner hole of the flange plate along the tapered hole walls of the guide hole, the gluing machine needle head and a fiber core can be easily inserted into the inner hole of the flange plate, and the assembly success rate of the optical fiber connector is increased.

Description

technical field [0001] The present invention relates to optical fiber connectors for optical signal transmission. Background technique [0002] The structure of existing FC, SC and other optical fiber connectors is as follows: figure 1 Shown: It includes a housing with the front end as the plug-in end, the housing includes a front sleeve 4 and a rear sleeve 6 assembled together, a connecting nut 2 rotates on the housing, and a flange with a ferrule 1 is arranged in the housing 3. The rear end of the flange extends into the inner hole of the rear sleeve. In order to ensure the axial movement of the flange when the connector is docked, there is a radial gap between the flange and the inner hole wall of the rear sleeve 5 . In the past, fiber optic connectors were manually assembled, and the optical fiber was manually inserted into the inner hole of the flange from back to front, and then the flange was assembled into the housing. Due to the low efficiency of manual assembly,...

AI Technical Summary

Problems solved by technology

Due to the low efficiency of manual assembly, it is currently trying to use automated assembly equipment to produce optical fiber connectors. However, the steps of automated assembly are: first assemble the ferrule, flange, spring 8, front sleeve, and rear sleeve, etc., and then Carry out the steps of glue injection, fiber stripping, fiber threading and subsequent grinding, because the parts are assembled first and then glue injection and fiber threading are performed. The flange is far away from the rear end of the back sleeve, and the glue injection machine head is very easy to inject during glue injection. It is blocked by the rear end face of the flange and cannot be inserted into the flange, and finally the assembly fails due to the glue overflowing the flange; in addition, it is very easy for the fiber core 7 to enter between the flange and the back sleeve Radial gap, or the core is inserted into the rear end face of the flange and the core is broken, which eventually leads to assembly failure
