Abstract

A sealed coaxial cable connector. A member of a moldable resilient material is provided at the junction between an internal cylindrical opening through the center of a connector body and an enlarged counterbore at the forward end of the body. The member, which may for example be molded to the rear shoulder of the counterbore, has an opening through its center which is sized so that the member coacts with the insulating layer of a coaxial cable, when the cable is inserted into the connector, to seal the opening. An external seal may also be provided by a gasket of a resilient material positioned at the forward end of a ferrule portion of the connector body, ahead of the connector outer conductor. The gasket is adapted to have a crimp ferrule pass over it, and to be compressed by the crimp ferrule when the ferrule is crimped to form a seal between the crimp ferrule and the body member. The rear end of the crimp ferrule is sealed by passing the ferrule over the outer insulating jacket of the cable.

Claims

1. A sealed connector for a coaxial cable having an inner conductor encircled by an annular insulating layer, an outer conductor, and an insulating jacket comprising:

a metallic body member having extending therethrough a cylindrical opening sized to accept said inner conductor and insulating layer, said opening having an enlarged counterbore coaxial therewith formed at its forward end which counterbore terminates in a shoulder at its rear end, said shoulder having a counterbore provided therein coaxial with said opening and having a diameter greater than that of said opening but less than that of said enlarged counterbore; and

means for providing a seal at the junction between said opening and said enlarged counterbore, said means including a resilient seal seated within and adhered to the walls of said counterbore of said shoulder, said seal being coaxial with said opening and having an internal opening with a diameter chosen sufficiently smaller than that of said insulating layer so that said member is compressed and displaced by said insulating layer, when said cable is inserted in said opening, to seal said opening.

2. A sealed connector for a coaxial cable having an inner conductor encircled by an annular insulating layer, an outer conductor, and an insulating jacket comprising:

a metallic body member having extending therethrough a cylindrical opening sized to accept said inner conductor and insulating layer, said opening having an enlarged counterbore coaxial therewith formed at its forward end which counterbore terminates in a shoulder at its rear end, said shoulder having a counterbore provided therein coaxial with said opening and having a diameter greater than that of said opening but less than that of said enlarged counterbore; and

means for providing a seal at the junction between said opening and said counterbore, said means including a washer seated in said counterbore of said shoulder, said washer having a resilient seal adhered to the wall of its inner opening, said seal being coaxial with said opening and having an internal opening with a diameter chosen sufficiently smaller than that of said insulating layer so that said member is compressed and displaced by said insulating layer when said cable is inserted in said opening to seal said opening.
