ABSTRACT:
An elongated hollow termination pin assembly for mechanically terminating a fiber bundle of a fiber optic cable. The pin assembly includes an elongated hollow pin with coaxially slidable outer sleeve and an O-ring of resilient material mounted in a groove about the pin immediately adjacent to the end of the sleeve toward the terminal end of the cable. A backward facing shoulder is provided about the circumference of the sleeve so that a retaining clip within the connector shell can restrain backward axial movement of the sleeve. The pin can slide within the sleeve, however, and is resiliently constrained by the O-ring to provide a positive abutment force at the interface of the fiber bundles, dampen contact vibrations, and absorb axial tolerances. Alternatively, the O-ring may be positioned between a forwardly facing shoulder on the connector body and the retaining clip, with a tine on the clip engaging a rearwardly facing shoulder on the pin.
