Problems solved by technology

[0003] The common method of the existing single-way optical fiber rotary connector is to use optical fiber alignment components to directly couple the optical signal from the rotating mechanism to the stationary mechanism. This coupling method has poor controllability, and there are no other auxiliary coupling or loss compensation devices; these Factors make the rotation and alignment of the optical path extremely difficult, while the performance index of the existing rotary connector is guaranteed by the machining accuracy, the production difficulty is high, and the product production pass rate is low; these factors restrict the development of the rotary signal transmission industry

Abstract

The invention relates to a device and method capable of realizing precise regulation of a rotary single-path optical fiber connector. The device consists of a static angle-regulating system and a rotary angle-regulating system which are combined with a precise bearing and a bearing end cover, wherein the rotary angle-regulating system consists of a rotary angle-regulating sleeve and a rotary fixed sleeve; and the static angle-regulating system comprises a static angle-regulating sleeve, a static fixed sleeve and a connector shell. The regulating method comprises the following steps of: regulating coordinates of the tail parts of the fixed sleeves in the rotary and static angle-regulating systems to realize precise regulation on an optical angle of an optical fiber collimating component; fixing the connector shell, and regulating and fixing the coordinates of the tail end of the fixed sleeve of the rotary angle-regulating system in the angle-regulating sleeve when the rotary angle-regulating system rotates; and keeping the rotary angle-regulating system rotating, regulating and fixing the coordinates of the tail end of the fixed sleeve of the static angle-regulating system in the angle-regulating sleeve. The device and the method disclosed by the invention are convenient to operate and easy to realize and meet the extremely high requirements of the rotary single-path optical fiber connector on processing precision and assembling precision.
