Abstract
The utility model discloses an Optical fiber branch device. The packaging slot of the optical fiber branch device in prior art is straight, so the external form is also straight. In application of the optical fiber gyroscope, the optical fiber branch device is installed in the ring of the gyroscope. Due to the length of the optical fiber branch device self attached with the minimum curvature radius allowed by the optical fiber, the gross duty size is difficult to decreased, and therefore, the miniaturization of the optical fiber gyroscope is limited and the accuracy is more increased. The utility model comprises an optical fiber, an optical fiber fusing cone, a packaging slot, a sealing sleeve pipe and an outer shell. The packaging slot is curved, the optical fiber fusing cone is agglutinated in the packaging slot, so the duty size of the optical fiber branch device in the gyroscope ring can be efficiently decreased, and it is favorable for the miniaturization of the optical fiber gyroscope and the increasing of the accuracy. The utility model is suitable to the technical field of optical fiber gyroscope, etc.
Description
Technical field
The utility model relates to a kind of branch's device that is used for Optical Fiber Transmission.
Background technology
The fiber optic tap device is widely used in optical fiber communication and fiber-optics gyroscope field.It by optical fiber, optical fiber melt cone, encapsulation groove, Sealed casing pipe and shell etc. constitute, 4 fiber ports are arranged or only keep 3 ports.It is the exposed position of two optical fiber is closed up or to kink that optical fiber melts cone, places that fusion drawn forms on the thermal-flame.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of fiber optic tap device with curved encapsulation groove is provided, and can effectively dwindle the ring diameter of optical fibre gyro, helps the raising of optical fibre gyro miniaturization and precision.
Fiber optic tap device of the present utility model comprises that optical fiber, optical fiber melt cone, encapsulation groove, Sealed casing pipe and shell etc.Described encapsulation groove is curved, and optical fiber melts cone and is bonded in the encapsulation groove, and the outside seals with Sealed casing pipe, and then in the shell of packing into.
Effect of the present utility model is, reduced the duty size of fiber optic tap device in the optical fibre gyro ring, reduced the ring diameter effectively, with further miniaturization and the raising precision that realizes optical fibre gyro, simultaneously fiber optic tap device effective length can be increased, thereby its package reliability can be improved and the adaptability of environmental baseline.
