ABSTRACT:
An improved connector pin assembly and method for concentrically aligning and terminating an optical fiber of a fiber optic cable with respect to the outer dimension of the pin negates the heretofore required epoxy or other adhesive for providing secure termination of an optical fiber within a terminal pin. The assembly includes a terminal pin having a fiber optic cable receiving bore extending into the pin from its rear end and a terminal end bore of smaller dimension extending into the terminal pin from the terminal pin forward terminating end. The terminal end bore communicates with the cable receiving bore and is concentric to the outer dimension of the terminating pin terminal end. A resilient insert member having a central aperture dimensioned for receiving the optical fiber and an outer portion which is greater in dimension than the terminal end bore when the insert member is in its free uncompressed state is forced into the terminal end bore. The terminal end bore uniformly compresses the resilient insert member thereby causing the central aperture to be uniformly contracted about the optical fiber threaded through the bores and the central aperture as the insert member is forced into the terminal end bore. As a result, the optical fiber is firmly gripped and disposed within the terminating pin by the resilient insert member concentrically with respect to the outer dimension of the terminating pin terminal end.
