Abstract
Apparatus for frictionally engaging and supporting a cylindrical, fiber optic component such as an axial ferrule is provided with the capability of releasably locking the component in the apparatus, thereby permitting coupling of the component for extended periods of time without degradation of light transmission. The apparatus includes a cylindrical, split spring bushing positioned in a cavity defined by a two-part housing and a set screw in a threaded bore extending radially through overlapped portions of both housing parts. The screw is advanced into contact with the bushing to apply inwardly radial pressure thereto, increasing the frictional engagement of the bushing with the component to essentially lock the component in the apparatus. In a preferred method of fabrication and use of the apparatus, the two housing parts are placed in fully assembled condition, without the bushing, and a radial bore is formed through the overlapped portions. The housing parts are then disassembled, the diameter of the bore portion in the outer part is enlarged and the bore portion of the inner part is tapped to provide internal threads. Both parts are then deburred and reassembled with the bushing in the cavity and the set screw in the threaded portion of the radial bore.
