Plastic fibre-optical rotating connector

Abstract

The invention provides a plastic fibre rotating connector. One end of the fixed end sleeve of a fixed head is embedded with a fixed end fibre and the other end thereof is embedded with a fixed end lens; the end surfaces of the fixed end fibre and the fixed end lens are closely matched with each other in a contacting way; a fixed metal sleeve is arranged outside the fixed end sleeve. A movable endfibre is embedded at one end of the movable end sleeve of the rotating head and a movable end lens is embedded at the other end thereof; the end surfaces of the movable end fibre and the movable end lens are closely matched with each other in a contacting way; a rotating metal sleeve is arranged outside the movable end sleeve. The fixed end fibre and the movable end fibre are plastic fibres; the fixed end fibre sleeve is arranged outside at the end of the fixed end fibre which is embedded into the fixed end sleeve; the movable end fibre sleeve is arranged outside at the end of the movable endfibre which is embedded into the movable end sleeve. The plastic fibre rotating connector of the invention solves the technical problems that: in the background technique, the numerical aperture and core diameter of the fibre are small, the requirements on the mechanical processing precision and the assembly coupling precision are extremely rigid, the coupling difficulty is large and the cost is high. The plastic fibre rotating connector is especially applicable to local area network with a plurality of connecting points, and the short-distance information transmission system.

Description

technical field [0001] The invention relates to an optical fiber rotary connector, in particular to a plastic optical fiber rotary connector. Background technique [0002] The optical fiber rotary connector is a precision optical device that uses optical fiber as the data transmission medium to solve the data transmission between the components of the rotary connection system. It can improve the mechanical performance, simplify the system operation, and avoid damage to the optical fiber due to the rotation of the movable joint. It is suitable for unlimited, continuous or intermittent rotation, and at the same time, it is necessary to transmit large-capacity data and signals from a fixed position to a rotating position. Widely used in all-round target finding systems and command systems that require free-rotating connectors, such as: between radar antennas and its on-board signal processing systems, between submarine robots and control ships, between industrial manipulators a...
