1. An F-type connector for mounting upon a terminal end of a coaxial cable having a bare central conductor extending a predetermined length from the planar end surface of an inner dielectric layer, said connector comprising:

  • a) a post member having a hollow, substantially cylindrical stem portion with a central axis and first end surrounded by a metal flange having a planar annular surface perpendicular to said central axis;

    b) means for securely maintaining said post in assembled relation with said terminal end of said cable;

    c) a nut including an internally threaded bore sized for threaded engagement with a hollow, threaded shaft at a port on video equipment to which said cable is to be electrically coupled, said shaft having a metal, terminal end;

    d) means for mounting said nut in encircling relation to at least a portion of said post including said flange for free rotation and limited axial movement between first and second positions relative to said post; and

    e) a spring biasing said nut toward said first position wherein said nut may be placed in alignment with said shaft and rotated not more than three revolutions to bring said terminal end of said shaft into contact, and thus RFI shielding relation, with said annular surface of said post, continued rotation of said nut moving said nut axially with respect to said post toward said second position against the biasing force of said spring.
