Problems solved by technology

Since the steel wire is flexible, and it will be bent to a certain extent during the cutting process and there is a gap between the steel wire and the inner hole, the ferrule processed by this processing method, when the process, equipment and raw materials are good, the ferrule can be inserted easily. The output angle of the finished core can only meet the standard of ≤0.3°, and cannot meet all the standards of ≤0.1°

Embodiment 1

[0040] refer to figure 1 and figure 2 As shown, this embodiment discloses a processing technology for a ceramic ferrule of an optical fiber connector. The ceramic ferrule 3 is provided with an inner hole 3.1, and the inner hole 3.1 extends to both ends of the ceramic ferrule. The processing of the ceramic ferrule 3 The process includes the following steps:

[0041] Step S1, placing a single ceramic ferrule 3 at the station between the grinding wheel 1 and the guide wheel 2, since the ceramic ferrule is processed individually, that is, the size of the grinding wheel 1 and the guide wheel 2 can be the same, which is mainly the same as that of the ceramic ferrule. Ferrule fit.

[0042] Step S2: Position the two ends of the ceramic ferrule 3, and use the end positioning method to replace the steel wire positioning method in the prior art, which solves the traditional unavoidable bending of the steel wire and the inner gap between the steel wire and the ferrule. hole clearance ...

Embodiment 2

[0054] refer to image 3 As shown, this embodiment also provides a processing device for realizing the processing of the ceramic ferrule of the optical fiber connector, including a grinding wheel 1 and a guide wheel 2, and also includes a positioning device. The positioning device includes a first hard metal thimble 4 and a second hard metal thimble. Hard metal thimble 5, the first hard metal thimble 4 cooperates with the positioning groove 8 at one end of the ceramic ferrule 3, the second hard metal thimble 5 cooperates with the inner hole 3.1 at the other end of the ceramic ferrule 3, the first hard metal thimble The thimble 4 and the second hard metal thimble 5 exert a clamping force on both ends of the ceramic ferrule 3 during the grinding process of the ceramic ferrule 3 for positioning.

[0055] As a preference, the processing device of this embodiment further includes a first power unit 9 connected to the first hard metal thimble 4, and / or a second power unit 10 connect...

Abstract

The invention discloses a processing technology of a ceramic ferrule. The processing technology comprises the steps that S1, a single ceramic ferrule is placed at a station between a grinding wheel and a guide wheel; S2, the two end parts of the ceramic ferrule are positioned; and S3, the guide wheel is started to drive the ceramic ferrule to rotate, and meanwhile the grinding wheel is started togrind the single ceramic ferrule. The invention further provides a processing device of the ceramic ferrule. According to the processing technology of the ceramic ferrule, when the single ceramic ferrule is processed, positioning is conducted at the two ends of the ceramic ferrule, unavoidable problems that a steel wire is bent due to stress and a gap exists between the steel wire and an inner hole of the ferrule in tradition are solved, and it is guaranteed that an emergence angle of the processed ferrule finished product meets the standard of being smaller than or equal to 0.1 degree in 100%; and the ceramic ferrule processed by adopting the technology is applied to an optical fiber connector, so that a step of adjusting points by adopting special equipment can be avoided, the cost is greatly reduced, and batch processing of the optical fiber connector is facilitated.

Description

technical field [0001] The invention relates to the technical field of communication products, and more specifically relates to a processing technology and a processing device for a ceramic ferrule of an optical fiber connector. Background technique [0002] Optical fiber connector is a device for detachable connection between optical fiber and optical fiber. It is used to precisely butt the two end faces of optical fiber, so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and make The impact on the system due to its intervention in the optical link is minimized, which is a basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems. [0003] The ceramic ferrule in the fiber optic connector is a ceramic cylinder used for precision alignment in the ceramic sleeve. It is made of zirconia cera...
