5. The shield of claim 1 , further comprising a conductive material plating.

6. The shield of claim 5 , wherein the conductive material plating is one of tin and tin-nickel.

7. The shield of claim 1 , wherein the at least one pre-formed cantilevered annular beam comprises a plurality of pre-formed cantilevered annular beams.

8. The shield of claim 1 , wherein the components comprise a coupler, a tubular post and a body.

9. The shield of claim 8 , wherein the inner segment is disposed between the tubular post and the body.

10. The shield of claim 8 , wherein the at least one pre-formed cantilevered annular beam exerts a spring-like force on a surface of the coupler.

11. A coaxial cable connector for coupling a coaxial cable to an equipment port, the coaxial cable including a center conductor surrounded by a dielectric material, the dielectric material being surrounded by an outer conductor, the coaxial cable connector comprising in combination:

a tubular post having a first end adapted to be inserted into the prepared end of the coaxial cable between the dielectric material and the outer conductor, and having a second end opposite the first end thereof;

a coupler having a first end rotatably secured over the second end of the tubular post, and having an opposing second end, the coupler including a central bore extending therethrough, a portion of the central bore proximate the second end of the coupler being adapted for engaging the equipment port;

a body secured to the tubular post and extending about the first end of the tubular post for receiving the outer conductor of the coaxial cable, wherein the body member contacts the coupler;

a resilient, electrically-conductive shield having an inner segment and at least one pre-formed cantilevered annular beam attached to the inner segment, wherein the inner segment is disposed between the tubular post and the body, and the at least one pre-formed cantilevered annular beam exerts a spring-like force on the coupler, and wherein the shield provides an electrically-conductive path between the tubular post and the coupler, and wherein the shield remains captured and secured and provides the electrically-conductive path independent of the tightness of the coaxial cable connector, wherein the at least one pre-formed cantilevered annular beam comprises an outer surface with an edge, and wherein the edge has a knife-like sharpness and provides a wiping action of surface oxides on a surface of the coupler.

12. The coaxial cable connector of claim 11 , wherein the shield is generally circular and the at least one pre-formed cantilevered annular beam is arcuately shaped.

13. The coaxial cable connector of claim 11 , wherein the second end of the tubular post has an enlarged shoulder comprising a first rearward facing annular shoulder and a second rearward facing annular shoulder.

14. The coaxial cable connector of claim 13 , wherein the inner segment is positioned between a face of the body and the second rearward facing annular shoulder thereby securing the shield in the coaxial cable connector by the inner segment.

15. The coaxial cable connector of claim 12 , wherein the coupler comprises a rearward facing annular surface, and wherein the at least one pre-formed cantilevered annular beam exerts a spring-like force on the coupler at the rearward facing annular surface.

16. The coaxial cable connector of claim 13 , wherein the shield is resilient relative to the longitudinal axis of the connector and maintains an acurately increased surface of sliding electrical contact between the shield and the rearward facing annular surface of the coupler.

17. The coaxial cable connector of claim 11 , wherein the shield provides for unrestricted rotation of the coupler.

18. The coaxial cable connector of claim 11 , wherein the shield maintains the electrically conductive path between the coaxial cable conductor and an equipment connection port of an appliance when the coupler is loosened from while in contact with the equipment connection port.
