Optical fiber connector capable of accurate positioning

Abstract

The invention discloses an optical fiber connector capable of accurate positioning, which comprises a connector socket and a connector plug, wherein the connector socket comprises a connector socket base, a locking wheel pressure ring, a locking wheel and an operating handle, and the connector socket base is fixed to an optical bottom plate of a confocal imaging system in a rigid manner; the locking wheel pressure ring, the locking wheel and the operating handle form a locking and limiting mechanism of the connector socket; the head part of the connector plug is provided with an axial positioning head, a rotary positioning head is arranged behind the axial positioning head, an optical fiber bundle passes through a hollow hole, and the optical fiber bundle and the connector plug are fixed to each other after being leveled; and the hollow hole faces just to a circular light passing hole when connector plug is inserted to the bottom part of a positioning groove of the connector socket base, and focused laser is injected into the optical fiber bundle through the circular light passing hole. The optical fiber connector adds a rotary positioning function, limits the optical fiber to rotate around the axis, achieves positioning in the rotational direction, applies a pressure on the connector through a spring, ensures stable and reliable locking of the connector, and can control the pressure.

Description

technical field [0001] The invention belongs to the field of optical technology, and more specifically relates to an optical fiber connector capable of precise positioning. Background technique [0002] In the confocal imaging system based on fiber bundles, 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 core of the fiber bundle after being focused. 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] During the imaging process, the scanning device will scan each core in tur...

Problems solved by technology

For example, a typical SMA fiber optic connector, with a connector aperture of 850um, the deviation of the aperture can reach 15um, which cannot meet the requirements of precise positioning. The use of general-purpose fiber optic connectors in confocal imaging systems needs to be done after each connection. Only by readjusting the optical path of the connector part can the end face of the fiber bundle be adjusted to the ideal position
