A fiber-optic connector for a cable with an optical fiber. The connector includes a first backpost having an exteriorly threaded forward portion, a rearward portion attachable to the cable, and a central passageway extending therethrough. The connector has a body with a forward portion, an interiorly threaded rearward portion, and a central passageway extending therethrough. The body threads have a pitch diameter and pitch thread which mate with the threads of the first backpost. A second backpost is positioned within the body central passageway, and has a forward portion which holds a ferrule in position, and a rearward portion which extends through a rearward opening in the body and into a forward opening of the first backpost. The second backpost rearward portion and the first backpost central passageway are non-cylindrical to prevent rotation of the second backpost. The second backpost has an exteriorly threaded central portion with threads corresponding to the pitch diameter and thread pitch of the threads of the first backpost to allow the second backpost to threadably engage and upon rotation pass by the body interior threads when the second backpost is inserted within the body during assembly of the connector. A shoulder of the body projects radially inward sufficient to limit forward movement of the second backpost. A spring biases the second backpost in the forward direction. A coupling nut is positioned around the body and has a threaded forward end portion for threaded engagement with an adaptor. The connector is designed for easy interchange of coupling nuts having various connector styles. |
