Problems solved by technology

[0005] 1. After the glue is injected into the tail handle, the glue curing time needs to be at least 20 minutes. During this period, the entire optical fiber connector cannot be moved. Once the external force is disturbed, the quality of the high and low temperature cycle of the connector will be unstable, and when the glue is cured The fiber cracked during the process, and the connector processing failed
[0006] 2. This manufacturing method is complex and requires manual glue injection. It cannot be automated and the production efficiency is not high.

Abstract

The invention discloses an optical fiber connector with a self-locking structure, which comprises a tail handle, a ferrule and an optical fiber. The tail handle is composed of a tail handle head and a tail handle tube integrally formed with the tail handle head. The ferrule is fixedly arranged in the tail handle head. The optical fiber is inserted into the ferrule through the tail handle tube. The optical fiber is fixedly locked to the tail handle and the ferrule via the self-locking structure. Compared with the prior art, optical fibers are directly and fixedly locked to the tail handle and the ferrule via the self-locking structure, so that the glue injection into the tail handle is not required. Therefore, after being locked and fixed, the optical fibers are less susceptible to the external interference. The displacement condition of the ferrule is avoided. The stability and the yield of products are effectively ensured. Meanwhile, the tail handle and a locking sleeve are integrally formed, thus being simple and convenient to manufacture. The automated production is realized. Meanwhile, the tail handle and the locking sleeve are simple and convenient in locking manner, and suitable for outdoor assembly. The production and assembly efficiency is improved.

Description

Technical field: [0001] The invention relates to an optical fiber connector, in particular to an optical fiber connector with a self-locking structure. Background technique: [0002] Such as figure 1 As shown, the existing optical fiber connector mainly includes a tail handle 100 , a ferrule 200 and an optical fiber 300 , and the optical fiber 300 is composed of a bare optical fiber 301 and a cladding 302 covering the bare optical fiber 301 . [0003] The manufacturing method of this optical fiber connector is: the ferrule 200 is fixedly installed at one end of the tail handle 100, and then glue is injected into the tail handle 100, and the optical fiber 300 is inserted into a proper position from the other end of the tail handle 100, and then the glue is heated and cured , so as to fix the tail handle 100, the ferrule 200 and the optical fiber 300 together. [0004] However, this production method has the following defects: [0005] 1. After the glue is injected into the...
