A coaxial cable connector for coupling an end of a coaxial cable to a terminal, the connector comprising a post and a coupler, wherein: the post comprises from a forward to rearward direction, a front end and then a back end, the back end is adapted to extend into an end of a coaxial cable; the post comprises an enlarged shoulder at the front end, the enlarged shoulder extending inside the coupler and including a contacting portion, a collar portion and rearward facing annular surface; the contacting portion of the post is of monolithic construction with the post and is at least partially circumscribing the post; the coupler has an internally projecting lip defining a through bore of the coupler; the collar portion of the post allows the coupler to rotate by means of a clearance fit with the through bore of the coupler; the lip has a forward facing surface, a rearward facing surface and an intermediate portion between the forward facing surface and the rearward facing surface; the contacting portion extends in a generally perpendicular orientation with respect to a rearward forward direction of the coaxial cable connector; characterised in that the contacting portion of the post contacts the forward facing surface of lip in a co-planar engagement; the contacting portion maintains the generally perpendicular orientation and facilitate electrical continuity between the post and the coupler to provide RF shielding such that the integrity of an electrical signal transmitted through coaxial cable connector is maintained regardless of the tightness of the coupling of the connector to the terminal; the rearward facing annular surface of the post limits forward axial movement of coupler by engaging forward facing surface of the lip. the post comprises from a forward to rearward direction, a front end and then a back end, the back end is adapted to extend into an end of a coaxial cable; the post comprises an enlarged shoulder at the front end, the enlarged shoulder extending inside the coupler and including a contacting portion, a collar portion and rearward facing annular surface; the contacting portion of the post is of monolithic construction with the post and is at least partially circumscribing the post; the coupler has an internally projecting lip defining a through bore of the coupler; the collar portion of the post allows the coupler to rotate by means of a clearance fit with the through bore of the coupler; the lip has a forward facing surface, a rearward facing surface and an intermediate portion between the forward facing surface and the rearward facing surface; the contacting portion extends in a generally perpendicular orientation with respect to a rearward forward direction of the coaxial cable connector; characterised in that the contacting portion of the post contacts the forward facing surface of lip in a co-planar engagement; the contacting portion maintains the generally perpendicular orientation and facilitate electrical continuity between the post and the coupler to provide RF shielding such that the integrity of an electrical signal transmitted through coaxial cable connector is maintained regardless of the tightness of the coupling of the connector to the terminal; the rearward facing annular surface of the post limits forward axial movement of coupler by engaging forward facing surface of the lip.
