Abstract

The invention relates to a fiber rotary connector, which combines optical system and mechanical system to complete optical signal transmission in the relative movement state. Collimator combines the prism to form the fiber rotary connector optical system, and mechanical system uses the planetary gear drive mechanism. The fiber exhaled light passes through the collimator to collimate to big light spot parallel rays, and when the parallel rays rotating with velocity v, the prism rotating with velocity v / 2 with the same direction, so the exhaled light and the incident light have the same position. The program features v / 2 velocity, and the same direction rotation, so the mechanical system totally uses 8 precision gears, 4 ceramic bearings, 6 double-sealed bearings, and the 8 gears have both rotation and revolution, considering two center round space as multiple planetary transmission loads; the incident parallel rays passes through the optical system, and with the prism all-reflection to form the corresponding exhaled parallel rays. The program can be very convenient to achieve space free rotation, optical signal two-way transmission.

Description

technical field [0001] The invention relates to an optical fiber rotary connector. Background technique [0002] US patent (US5157745) discloses a multi-channel rotary optical fiber connector, which is composed of prisms, bearings, gears, optical fiber alignment mechanisms, rotating shafts, etc. The rotating body is connected to the housing through bearings, and there are prisms at both ends The mechanism realizes the purpose of synchronizing the input and output through the gear transmission mechanism. Due to the complex structure and large size of the optical fiber collimation mechanism, it is difficult to install. Contents of the invention [0003] The object of the present invention is to propose a fiber optic rotary connector with simple structure, small volume and easy installation. The technical solution of the present invention is: an end cover component, a fixed end collimator component, an outer casing, a gear component, a linkage mechanism component, a prism m...
