  • grounding of the coaxial cable 10 through the connector 100 may be accomplished by advancing the connector 100 onto an interface port 20 until a surface of the interface port mates with the mating edge conductive member 70. Because the mating edge conductive member70 is located such that it makes physical and electrical contact with post 40, grounding may be extended from the post 40 through the mating edge conductive member 70 and then through the mated interface port 20.

  • Advancement of the connector 100 onto the interface port 20 may involve the threading on of attached threaded nut 30 of connector 100 until a surface of the interface port 20 abuts the mating edge conductive member 70 and axial progression of the advancing connector 100 is hindered by the abutment.
  • embodiments of the connector 100 may be advanced onto an interface port 20 without threading and involvement of a threaded nut 30.

Furthermore, the particularly embodied connector body conductive member 80 may physically contact and make a seal with outer internal wall 39 of threaded nut 30. Moreover, the connector body conductive member 80 may physically contact and seal against the surface of connector body 50. Accordingly, where the connector body 50 is comprised of conductive material and the threaded nut 30 is comprised of conductive material, the connector body conductive member 80 may electrically couple the connector body 50 and the threaded nut 30.
