Reusable fixing structure

Abstract

The invention provides a reusable fixing structure which comprises a fixing body. The fixing body is made of a substance with a high friction coefficient, and the fixing body comprises an inserting part and a balancing part. During use, a to-be-fixed object is extruded through the inserting part or the balancing part and is fixed through friction force between the inserting part and the balancing part. When the to-be-fixed object is the bare fiber, the end face of the bare fiber is manufactured, and various performance tests of the laser are completed, the optical fiber does not need to be cut off, the flat end face of the optical fiber cannot be damaged, the optical fiber does not need to be discarded, length reduction caused by repeated manufacturing of the end face of the optical fiber can be avoided, and materials are saved. In the inserting process, the outer wall of the bare fiber abuts against and is fixed to the inner wall face of the inserting hole, and the bare fiber can be prevented from inclining in the inserting process. Meanwhile, the reusable fixing structure of the structure is used for fixing the bare fiber, and an ultraviolet lamp and ultraviolet curing glue are not needed; and the fixing structure can be repeatedly used, so that the material cost is saved. And the bare fiber is fast to install and fix without waiting for curing of the ultraviolet curing glue.

Description

technical field

[0001] The invention relates to the technical field of optical fiber fixing equipment, in particular to a reusable fixing structure. Background technique

[0002] The energy inside the semiconductor laser is output through the optical fiber. The current optical fiber output end will use different optical fiber output methods due to different applicable products. Among them, semiconductor lasers that output in the form of bare optical fibers need to test various performances of semiconductor lasers during the production process of semiconductor lasers. The test instrument is connected through a bare optical fiber located outside the semiconductor laser to output the energy of the semiconductor laser to the test instrument. For the test instrument, the bare optical fiber needs to have the following properties: the end face of the output end of the optical fiber is a smooth plane; both the fixed fiber and the output end of the optical fiber are fixed. Therefor...
