Center conductor engagement mechanism

1. A center conductor engagement member comprising:

a body;

a resilient contact region having a first end and a second end integral with the body, the resilient contact region being substantially curvilinear from the first end to the second end; and

a non-conductive insert configured to engage the first end of the resilient region and resist radial inward displacement thereof;

wherein the contact region arcs from the insert to the body and defines a curved external surface configured to engage an internal surface of a coaxial cable conductor.

2. The center conductor seizing member of claim 1 , wherein the resilient contact region includes a plurality of resilient contact fingers.

3. The center conductor seizing member of claim 2 , wherein the insert includes an annular groove configured to accept an internal annular protrusion located on an inner surface of the resilient contact fingers.

4. The center conductor seizing member of claim 1 , wherein the insert ensures adequate contact force between a hollow center conductor and the resilient contact region.

5. The center conductor seizing member of claim 1 , further including an external contact interface at an end distal to the resilient contact region.

6. The center conductor seizing member of claim 5 , wherein the body portion connects the resilient contact region and the external contact interface.

7. The center conductor engagement member of claim 1 , wherein the insert is comprised of at least one of a conductive and non-conductive material.

8. The center conductor engagement member of claim 3 , further including an elastomeric band placed within the annular groove of the insert to adjust a stiffness of the resilient contact region.

9. The center conductor engagement member of claim 7 , wherein a coaxial cable connector having the center conductor engagement member achieves an intermodulation level below −155 dBc and return loss below −45 dB.

10. A center conductor engagement member comprising:

a resilient contact region having a substantially curvilinear contour from a first end to a second end, the second end of the resilient contact region being integral with a body portion, the resilient contact region having one or more axial through-slots defining a plurality of resilient contact fingers,

each of the plurality of resilient contact fingers being radially biased inwardly and defining an outwardly-curved external surface configured to engage an internal surface of a cable conductor the outwardly-curved external surface defining an outer diameter which is a maximum at a vertex of the outwardly-curved external surface; and

a non-conductive annular insert having an internal groove cooperating with a protrusion on an end of each resilient contact finger, the annular insert resisting movement of the plurality of resilient contact fingers in a radial inward direction, the insert resisting radial inward displacement of the contact region to maintain contact of the external surface with the cable conductor.

11. The center conductor engagement member of claim 10 , wherein the insert is comprised of at least one of a conductive and non-conductive material.

12. The center conductor engagement member of claim 10 , wherein the insert is a plastic ring.

13. The center conductor engagement member of claim 10 , further including an elastomeric band placed within the annular groove of the insert to adjust a stiffness of the resilient contact region.

14. The center conductor engagement member of claim 10 , wherein a coaxial cable connector having the center conductor engagement member achieves an intermodulation level below −155 dBc and return loss below −45 dB.

15. A method of engaging a center conductor of a coaxial cable comprising: disposing a center conductor engagement member within a coaxial cable connector, wherein the center conductor engagement member includes a resilient contact region having a first end and a second end, the resilient contact region configured to produce a substantially curvilinear external surface which arcs from the first end to the second end, wherein the second end of the resilient contact region is integral with a body portion, and a non-conductive insert engageable with the first end of the resilient contact region to retain the second end of the resilient contact region; and mating a center conductor of a coaxial cable with the center conductor engagement member, wherein the contact region is biased inwardly against the insert and wherein the substantially curvilinear external surface of the center conductor engagement member is configured to be inserted within, and engage an inner surface of, the center conductor, the insert resisting radial inward displacement of the contact region to maintain contact of the external surface with the cable conductor.

16. The method of claim 15 , wherein the resilient contact region includes a plurality of resilient contact fingers.

17. The method of claim 15 , wherein the insert includes an annular groove configured to accept an internal annular protrusion located on an inner surface of the resilient contact fingers.

18. The method of claim 15 , wherein the insert ensures adequate contact force between a hollow center conductor and the resilient contact region.

19. The method of claim 15 , further including an external contact interface at an end distal to the resilient contact region.
