Optical fiber fixture for observing and analyzing breaking point of optical fiber

Abstract

An optical fiber fixture for observing and analyzing the breaking point of an optical fiber belongs to the technical field of tools and fixture. The optical fiber fixture comprises left and right semicircular fiber clamping blocks, a fiber clamping block synchronous displacement connecting mechanism, and a push rod. The face-to-face sides of the left and right semicircular fiber clamping blocks are closed or separated. The fiber clamping block synchronous displacement connecting mechanism is arranged on the right semicircular fiber clamping block, and is connected with the left semicircular fiber clamping block. The push rod is arranged on the left semicircular fiber clamping block. When the left end of the push rod is pushed by external force, the right end of the push rod acts on the side, facing the left semicircular fiber clamping block, of the right semicircular fiber clamping block, and the left semicircular fiber clamping block and the right semicircular fiber clamping block areseparated against the counterforce of the fiber clamping block synchronous displacement connecting mechanism. When the action of the external force on the left end of the push rod is released, the left and right semicircular fiber clamping blocks actively move to each other and are closed under the action of the restoring force of the fiber clamping block synchronous displacement connecting mechanism. Optical fibers are prevented from getting out. The requirement for observing the end faces and side faces of the breaking point of an optical fiber is satisfied. The optical fiber fixture is small, and does not interfere with an observation device. The optical fiber fixture is simple in structure and easy to make.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to an optical fiber fixture for observing and analyzing optical fiber breakage points. Background technique [0002] As known in the industry, in order to ensure the quality of optical fiber, optical fiber manufacturers need to observe and analyze the fractured part of the optical fiber, that is, the aforementioned fracture point (also called "crack source"). Because the optical fiber is very thin, the fracture point cannot be observed with the naked eye, so it is usually carried out under an optical microscope and the optical fiber needs to be rotated to adjust the angle of the optical fiber when observing the side of the optical fiber. Due to the lack of fixtures that can precisely position the optical fiber in the prior art, the observer often positions the optical fiber by pinching the fingers. The shortcomings of this method are: the observer's work intensity is hi...

Problems solved by technology

It is based on this factor that there is no technical revelation of an optical fiber clamp suitable for clamping the optical fiber to be observed and suitable for placing on the microscope stage of an optical microscope in the Chinese and foreign patents and non-patent literature disclosed so far.
