ABSTRACT:
A connector assembly for terminating a shielded coaxial cable includes a female connector element having a bore containing an electrical contact and a male connector assembly including a plurality of individual connecting members carried by an end portion of the cable and received within the bore. The connecting members include a radially expandable shield connector affixed to the end of the cable, an annular thrust washer received on the cable for expanding the shield connector, an elastomeric O-ring seal received on the cable adjacent the thrust washer, a cylindrical plunger slidably received on the cable for engaging the O-ring seal and a cap nut threadably engaged with the female connector for urging the plunger in an axial direction and toward the O-ring seal whereby to urge the central conductor within the cable into electrical contacting engagement with the electrical contact, radially expand the shield connector within the bore and radially expand the O-ring into sealing engagement with the wall of the bore and the outer jacket of the cable in response to force applied to the O-ring seal by the plunger when the cap nut is rotated in a tightening direction relative to the female connector. A method for making the connector assembly is also disclosed.
