Optical fiber rotary connector for multichannel optical fiber early warning equipment

Abstract

The invention discloses an optical fiber rotary connector based on multichannel optical fiber early warning equipment, which comprises a stator shell and a rotor sleeve rotatably connected to the interior of the stator shell, a through hole matched with the rotor sleeve is formed in the stator shell, and the invention relates to the technical field of optical fiber early warning. According to theoptical fiber rotary connector, the rotor sleeve can be used in the stator shell for a long time, and the pressure generated by the pressing plate on the buffer spring is adjusted, so that the pressing force between rollers in the extrusion plate and the surface of the rotor sleeve is controlled; the problem that the optical fiber off-axis deviation becomes larger and larger due to increase of abrasion between the rotor sleeve and the stator shell during long-time rotation is avoided; and through the arrangement of the two movable bearings, the problem that the rotor sleeve deviates and shakesduring rotation can be effectively prevented, so that optical signals are stably transmitted, the coupling efficiency is improved, and good conditions are created for subsequent optical fiber early warning work.

Description

technical field [0001] The invention relates to the technical field of optical fiber early warning, in particular to an optical fiber rotary connector based on multi-channel optical fiber early warning equipment. Background technique [0002] Optical fiber rotary connector is also called optical fiber slip ring, optical fiber rotary joint, optical hinge, etc. Its function is to solve the problem of optical signal transmission between relative rotating parts, that is, to ensure that the transmission of optical signal is not interrupted due to rotation, and it is compatible with traditional electrical connections. Compared with optical fiber connectors, optical fiber rotary connectors have the following advantages: 1. Use light for signal transmission, no electromagnetic leakage, good confidentiality, anti-electromagnetic interference, 2. Contactless transmission, no wear, long life, up to 5 million revolutions, No friction, can be used in flammable and explosive environments....

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an optical fiber rotary connector based on multi-channel optical fiber early warning equipment, which solves the problem of wear and tear between the two optical fibers when the rotor sleeve rotates inside the stator housing. The positional deviation between the centerline shafts of the rotor is getting bigger and bigger, which in turn leads to the problem that the rotor sleeve is easy to move inside the stator housing and the optical fiber is shaken
