ABSTRACT:
An optical fiber rotary coupler includes an elongated support member adapted to be secured within the driver shaft of an electrical slip ring assembly and positioned on the axis of rotation of the driver shaft. Optical fibers are supported in connector bodies having end portions supported by radial bearings disposed within the bore of a coupler housing member. Lateral and angular alignment are maintained by the radial bearings in the housing bore and axial spacing of the connector body ends is maintained by dimensional control of the length of the bearing support housing, the thickness of two cylindrical thrust washers and the length of the connector body end portions with respect to a control surface or shoulder on each connector body.
