Abstract
The rotary-joint device has the design function of maintaining accurate positioning of the ends of optical fiber conductors during relative rotation of external bodies to which the joint is coupled. The device comprises a male ferrule and a female ferrule so arranged as to form a shaft rotatably mounted within a sleeve with a close but compliant fit, an abutment device for limiting the axial displacement of the sleeve, means for centering the ends of the conductors, and means for securing said ferrules to external connector bodies so as to form a rigid coupling and a semi-rigid coupling respectively.
