Des-backbone winding ring chucking appliance for optical fiber gyroscope without rise optical fiber ring

Abstract

The invention discloses a de-framing coil clamp for non-upper edge optic fiber ring of optic fiber gyroscope, composed of a coil A clamp (1), a coil B clamp (2), a round ring (3), a optic fiber ring (4), and a de-framing ring (5), the round ring (3) is installed on outer ring of end face (2b) of the coil B clamp (2), the de-framing ring (5) is sleeved in the round ring (3), and installed on D lug boss (21) of the coil B clamp (2); one end of the optic fiber ring (4) contacts with A end face (5) of the de-framing ring (5), the other end of the optic fiber ring (4) contacts with B recessed cavity (11) of the coil A clamp (1); the coil A clamp (1) is connected with the coil B clamp (2) via screws. The upper part of optic fiber frame (42) of optic fiber (4) according to the invention are in free state without being limited by the upper edge, and being extruded under condition of vibration or temperature change, meanwhile, the lower part of the optic fiber coil (41) contacts with the optic fiber frame (42) to realize supporting effect and distribute the temperature gradient along the axle line direction.

Description

technical field [0001] The invention relates to the technical fields of optical fiber sensing, optical fiber gyroscope and orbiting, and is especially suitable for the application field of inertial navigation technology with small volume and harsh temperature conditions. Background technique [0002] Optical fiber gyroscope is a sensor used to detect the angular rate of carrier motion.

Problems solved by technology

[0004] The current optical fiber coil structure is mostly "I"-shaped structure. The skeleton structure on the upper and lower sides and in the middle will constrain the optical fiber coil. When the vibration conditions and temperature change, the coil will be squeezed, and at the same time, the unreasonable direction of heat flow will be conducted. , resulting in stress and uneven distribution of temperature field inside the fiber optic coil
