种光纤陀螺磁屏蔽罩

本发明属于光纤陀螺技术，涉及种可重用、易安装拆卸的光纤陀螺磁屏蔽罩。所述光纤陀螺磁屏蔽罩包括上屏蔽罩、下屏蔽罩、基座、骨架、光纤环。其中，上屏蔽罩内环位于骨架内圆柱面与下屏蔽罩侧壁之间，光纤环绕指在骨架外圆周，并由上屏蔽罩封闭。所述上屏蔽罩盖板、上屏蔽罩内环、下屏蔽罩侧壁、下屏蔽罩底板、上屏蔽罩底板、上屏蔽罩外环将构成闭合磁路，该闭合磁路恰好将光纤陀螺光路中磁敏感部分包围而且与光的传播方向垂直，实现高性能的磁屏蔽，此外起到保护光纤环的作用。另外，本发明光纤陀螺磁屏蔽罩在装配过程中仅使用紧固件完成各零部件装配，未使用胶粘或者焊接等方式，屏蔽罩装配、拆卸简单易行。 The invention belongs to the fiber-optic gyroscope technology, and relates to a magnetic shielding case of a fiber-optic gyroscope, which is reusable, and easy to assemble and disassemble. The magnetic shielding case of the fiber-optic gyroscope comprises an upper shielding case, a lower shielding case, a base, a skeleton and a fiber-optic ring, wherein an upper shielding case inner ring is located between the inner cylindrical surface of the skeleton and a lower shielding case side wall, the fiber-optic ring surrounds the outer periphery of the skeleton and is closed by the upper shielding case. An upper shielding case cover plate, the upper shielding case inner ring, the lower shielding case side wall, a lower shielding case bot
