Abstract
A coaxial cable connector includes a connector body having a rearward cable receiving end and a gripping ferrule fixed within the rearward cable receiving end of the connector body. The gripping ferrule includes at least one flexible finger deflected in a radially inward direction and extending in a forward direction opposite the rearward cable receiving end of the connector body for permitting forward insertion of a cable into the connector body and for gripping the cable to prevent rearward removal of the cable from the connector body.
Claims18
A coaxial cable connector comprising:
- a connector body having a rearward cable receiving end;
- a stationary gripping ferrule fixed within said rearward cable receiving end of said connector body, said gripping ferrule including at least one flexible finger deflected in a radially inward direction and extending in a forward direction opposite said rearward cable receiving end of said connector body for permitting forward insertion of a cable into said connector body and for gripping the cable to prevent rearward removal of the cable from said connector body;
- an annular post disposed within said connector body, said annular post including a tubular extension extending axially into said gripping ferrule;
- and
- a nut rotatably coupled to said post, wherein the cable is secured to the connector without any axial movement of said gripping ferrule.
A coaxial cable connector comprising:
- a connector body having a rearward cable receiving end;
- a stationary gripping ferrule fixed within said rearward cable receiving end of said connector body, said gripping ferrule including at least one flexible finger deflected in a radially inward direction and extending in a forward direction opposite said rearward cable receiving end of said connector body for permitting forward insertion of a cable into said connector body and for gripping the cable to prevent rearward removal of the cable from said connector body, wherein said gripping ferrule further includes an annular radially inwardly directed flexible seal disposed on an inner rearward surface thereof for providing a substantially water-tight seal against the cable inserted into the connector;
- and
- an annular post disposed within said connector body, said annular post including a tubular extension extending axially into said gripping ferrule and terminating at a radially outwardly extending barb, said barb being disposed radially juxtaposed to said gripping ferrule flexible seal.
A method for terminating a coaxial cable in a connector comprising the step of inserting an end of a coaxial cable into a rearward cable receiving end of a connector body, the connector body having a stationary gripping ferrule fixed within said rearward cable receiving end of said connector body which permits forward insertion of the cable into the body but prevents rearward removal of the cable from the body, wherein the cable is secured to the connector without any axial movement of said gripping ferrules wherein said gripping ferrule prevents rearward removal of the cable with at least one flexible finger deflected in a radially inward direction and extending in a forward direction opposite said rearward cable receiving end of said connector, said finger gripping the cable to prevent rearward removal thereof,
- wherein said connector further comprises an annular post disposed within said connector body and including a tubular extension extending axially into said gripping ferrule, and wherein said cable inserting step comprises the step of passing at least an outer jacket of the cable through an annular gap defined between said flexible finger and said post tubular extension during forward insertion of the cable into said connector body.
