Optical fiber coupler capable of locking recognition

Abstract

The invention discloses an optical fiber coupler capable of locking recognition comprising a coupler plug and a coupler socket. The coupler socket comprises a bracket provided with an insertion slot, a locking slot, a tongue slot and a receiving slot; a locking mechanism provided with a pressing plate, a locking tongue, and a handle, wherein a locking wall is formed in the inner wall of the pressing plate and is capable of driving the locking tongue to be abutted against the coupler plug; and a cover plate sleeving the pressing plate and having one end connected with the bracket. The coupler plug comprises a plug body and a contact circuit board. The contact circuit board has a first contact capable of abutting against a plug chip and a second contact abutted against the inner wall of the pressing plate. The locking mechanism controls the rotation of the locking wall by means of the rotation of the pressing plate, thereby driving the locking tongue to move axially toward the insertion slot to abut against the plug body, and further locking the plug body. Further, the plug chip and the contact circuit board are in cooperation, it is determined that the plug is locked when the second contact is abutted against the inner wall of the pressing plate, thereby improving accuracy of locking positioning.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a lockable and identifiable optical fiber coupler. Background technique [0002] In the fiber bundle-based confocal imaging system, the laser emits laser light, scans the end face of the fiber bundle through the laser scanning device and the coupling objective lens, and injects the laser into each fiber core of the fiber bundle after focusing. The diameter of the core is approximately 2-3um. At the other end of the fiber bundle, the injected laser light is focused on the object to be observed through the micro-objective lens, and the object to be observed emits fluorescence under the excitation of the injected laser light, and the fluorescence returns along the same path through the core of the fiber bundle, and is finally detected by the detector captured and imaged. [0003] Therefore, the precise positioning between the coupling objective lens and the fiber bundle is a key ...
