Abstract

A coaxial cable connector includes tubular post, a coupler secured over an end of the tubular post for securing the connector to an appliance, and an outer body secured to the tubular post. An electrical grounding path is maintained between the coupler and the tubular post whether or not the coupler is tightly fastened to the appliance. The electrical grounding path is provided by a resilient, electrically-conductive grounding member disposed between the tubular post and the coupler. Alternatively, the connector includes conductive grease at a point where mating portions of the tubular post and coupler have closely matching dimensions.

Claims

1. A coaxial cable connector having a grounding member, a post and a nut, the grounding member comprising:

a metallic band comprising first and second side edges and a width extending between the first and second side edges, said metallic band comprising of a pair of opposing radial walls extending away from the first and second side edges along a pair of radial paths extending radially from the width and being composed at least partially of electrically conductive material, and

a contact portion defined by the radial wall, wherein the contact portion contacts the group members that includes the post and the nut and provides for an electrically-conductive path through the post and the nut.

2. A grounding member for a coaxial cable connector having a post and a nut, comprising:

a ring portion composed at least partially of electrically conductive material, and

a contact portion composed at least partially of a plurality of circumferential spring members projecting from respective base portions in a plane of the ring to respective movable portions displaced from the plane of the ring along a circumferential path of the ring, wherein

the spring members are arranged symmetrically about the ring portion,

respective base and movable portions of each circumferential spring member lie predominantly along a common circumferential path, and

the contact portion provides for an electrically-conductive path through the post and the nut.

3. The grounding member of claim 2, wherein the ring portion extends at least partially around the post, and wherein the at least one contact portion contacts the nut, and wherein the at least one contact portion contacts the post.

4. The grounding member of claim 2, wherein the contact portion is a plurality of fingers extending radially from the ring portion.

5. The grounding member of claim 4, wherein the plurality of fingers extend at about a 45°

angle from the plane of the ring portion.

6. The grounding member of claim 4, wherein the plurality of fingers project at approximately a 30°

angle from the plane of the ring.

7. The grounding member of claim 2 wherein, collectively, the circumferential spring members track a common circumference of the grounding member.

8. The grounding member of claim 2 wherein the circumferential spring members do not extend radially inwardly toward a center of the grounding member.

9. A grounding member for a coaxial cable connector having a post and a nut, comprising a generally arcuate shaped member, composed at least partially of electrically conductive material, and a contact portion of the generally arcuate shaped member, wherein:

the at least one contact portion provides for an electrically-conductive path through the post and the nut;

the generally arcuate shaped member comprises a circumferential metallic band; and

the circumferential metallic band has a general circular shape and approximates a section of a hollow cylinder that extends between first and second opposing ends.

10. The grounding member of claim 9, wherein the generally arcuate shaped member is C-shaped member.

11. The grounding member of claim 10, wherein the C-shaped member defines a circular broken ring extending over an arc of about at least 225 degrees.

12. The grounding member of claim 10, wherein the C-shaped member is a metal clip that has an arcuate curvature that is non-circular.

13. The grounding member of claim 9, wherein the generally arcuate shaped member is a stainless steel wire having a wire diameter of between about 0.010-inch and 0.020-inch.

14. The grounding member of claim 13, wherein the stainless steel wire has a diameter of about 0.016-inch.

15. The grounding member of claim 9, wherein at least a portion of the generally arcuate member positions in an annular recess in the nut.

16. The grounding member of claim 15, wherein the contact portion engages the nut at the annular recess.

17. The grounding member of claim 9, wherein the contact portion comprises internal lugs around an inner perimeter of the generally arcuate member, and wherein the internal lugs contact the post.

18. The grounding member of claim 9, wherein the contact portion comprises external lugs around an outer perimeter of the generally arcuate member, wherein the external lugs contact the nut.

19. The grounding member of claim 9, wherein the circumferential metallic band has first and second opposing side edges extending along a length of the circumferential metallic band.

20. The grounding member of claim 19, wherein the circumferential metallic band includes a first generally radial wall extending from the first side edge in a first radial direction, and a second generally radial wall extending from the second side edge generally in the first radial direction.

21. The grounding member of claim 20, the circumferential metallic band contacts a first one of the group of members that includes the nut and the post, and wherein the first and second radial walls contact the second of the group of members that includes the nut and the post.

22. The grounding member of claim 19, wherein the circumferential metallic band is formed along a width into a generally concave shape with the first and second side edges projecting generally in a first radial direction.

23. The grounding member of claim 19, wherein the contact portion comprises a plurality of projections, and wherein the first and second side edges contact a first one of a group of members that includes the nut and the post, and the plurality of projections contact a second one of the group of members that includes the nut and the post.
