<p>A termination arrangement for fiber optic cables includes a precision ceramic guide press fit into a sleeve on both the socket and pin termini. The precision ceramic guide (31) of the socket terminus (30) is extended through a bushing (57) and alignment sleeve (74), and a compression spring (59) is positioned between the bushing (57) and a stepped washer (58) secured in the connector so that the bushing (57), sleeve (74), and precision ceramic guide (31) may all be moved relative to the stepped washer (58) upon insertion of the ceramic guide (31) of the pin terminus (30) into the alignment sleeve (74). The length of each terminus is chosen so that any grommet (72) on an environmentally sealed connector will always fall on a portion of the body which has the same diameter for each terminus so that one grommet can be used with a variety of different size cables. A rear section of both the pin and socket terminus (30) bodies are stepped down to provide an area for the strength member of the fiber optic cable to be terminated to. By applying epoxy (47) to the stepped down diameter of the rear bodies and the fiber optic cable jacketing, the strength member can be evenly distributed over the rear of the bodies and a shrink tube (48) can be brought up over the outer jacketing of the fiber optic cable to the appropriate position and shrunk down in order to cure the epoxy (47), captivate the strength member, and seal the shrink tube (48) to the fiber optic cable jacketing. The sleeve may alternatively be extended through the stepped washer and terminate in a threaded portion onto which the bushing may be threaded, the precision ceramic guide (31) being press fit into the bushing rather than the sleeve so as to minimize the length of the hole that must be produced in the precision ceramic guide (31). <IMAGE></p> |
