Abstract: An improved plug connector includes a rear cable connection module individually sized to each cable required and a front outer contact portion arranged such that the modular rear cable connection component may be press fit into the outer contact portion. In order to assemble the connector, an insulated inner contact assembly is fitted into either the cable connection module or the outer contact front portion, and is retained and positioned therein when the outer contact front portion is press fit onto the cable connection module. In addition, a coupling nut is provided which may be snap fit onto the outer contact by means of a split ring and flat retaining washer assembly encapsulated in the coupling nut.

Abstract: An assembly for use in a fiber optic connector for aligning and spacing the terminal ends of a pair of fiber optic cables to achieve efficient light transfer includes a pair of terminal pins, each having a bore for receiving one of the cables and an external shoulder. A resilient sleeve is tightly received over the terminal pins to align the terminal ends in facing relation and abuts the terminal pin shoulders to effect a predetermined close spacing of the terminal ends to provide efficient light transfer between the pair of fiber optic cables.In a preferred form, each terminal pin includes an insert member which has a concentric channel for receiving and aligning one of the fiber optic cables concentric with the outer dimension of the terminal pin.
