Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber slip rings, in particular to a lever structure for preventing radial force of an optical fiber slip ring. Background Art

[0002] Fiber optic rotary connector is also called fiber optic slip ring, fiber optic rotary joint, optical hinge, etc. Its function is to solve the problem of optical signal transmission between relatively rotating parts, that is, to ensure that the transmission of optical signals is not interrupted due to rotation. With the maturity and promotion of fiber optic slip ring technology, it will gradually be widely used in photoelectric signal transmission. Fiber optic slip ring uses optical fiber as the transmission medium and completes the transmission of optical signals through the rotor (rotating part) and the stator (fixed part).

Although the direct connection structure of the current fiber optic slip ring can basically meet the transmission requirements, the fiber optic slip ring is easily damaged by radial forces, resulting in damage and failure of the fiber optic slip ring, which has seriously affected the quality and stability of equipment connection transmission and is not practical.
