Abstract

The invention discloses a butt-joint type single-core optical rotating connector with an optical fiber collimator and an installation method thereof. The butt-joint type single-core optical rotating connector with the optical fiber collimator comprises rotating end optical fiber collimators, stationary end optical fiber collimators, rotors, bearing assemblies, stationary end installation covers and installation shells. The bearing assemblies comprise first bearings, second bearings and bearing blocking rings. The butt-joint type single-core optical rotating connector is characterized in that the bearing assemblies are fixed between the rotors and the installation shells, and elastic elements are located between bearings and the installation covers. According to the butt-joint type single-core optical rotating connector with the optical fiber collimator, the bearings can be compressed, clearance in the axial direction is reduced, and stability of components under the conditions of temperature change and vibration impact is improved. According to the installation method of the butt-joint type single-core optical rotating connector with the optical fiber collimator, the problem of angle and position errors between the optical rotating connector and rotating shafts during installation is solved, and the collimator can be installed quickly and effectively.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to an optical fiber collimator docking type single-core optical rotary connector used for optical signal transmission between relatively rotating devices in an optical fiber communication system and an installation method thereof. Background technique [0002] Optical fiber communication has been widely used due to its many advantages such as huge bandwidth, strong anti-interference and small loss. In some applications, optical fiber communication between two mutually rotating devices is required, such as between the towed optical fiber communication cable in the sea and the mother ship, between the vehicle and the radar antenna, and between the hot air balloon and the ground station. These application scenarios all require optical rotary connectors. Fixing the stationary part and the rotating part of the optical rotary connector between two mutually...
