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 pat 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

1-25. -25. (canceled)

26. 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. 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;

b. 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;

c. a body member 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; and

d. a resilient, electrically-conductive grounding member disposed between the tubular post and the coupler, the grounding member contacting both the tubular post and the coupler for providing an electrically-conductive path therebetween;

wherein the tubular post includes an enlarged shoulder at the second end thereof extending inside the coupler and wherein at least a portion of the grounding member contacting the tubular post surrounds the enlarged shoulder of the tubular post.

27. The coaxial cable connector of claim 26, wherein at least a portion of the grounding member does not contact the tubular post and is angled relative to the portion of the grounding member that contacts the tubular post.

28. 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. 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;

b. 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;

c. a body member 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; and

d. a resilient, electrically-conductive grounding member disposed between the tubular post and the coupler, the grounding member contacting both the tubular post and the coupler for providing an electrically-conductive path therebetween;

wherein the coaxial cable connector extends along a longitudinal axis and at least a portion of the grounding member contacting the tubular post coextends with the tubular post along a length parallel to the longitudinal axis.

29. The coaxial cable connector of claim 28, wherein at least a portion of the grounding member does not contact the tubular post and is angled relative to the portion of the grounding member that contacts the tubular post.

30. The coaxial cable connector of claim 29, wherein the portion of the grounding member that is angled relative to the portion of the grounding member that contacts the tubular post is angled radially outward.

31. 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. 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;

b. 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;

c. a body member 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; and

d. a resilient, electrically-conductive grounding member disposed between the tubular post and the coupler, the grounding member contacting both the tubular post and the coupler for providing an electrically-conductive path therebetween;

wherein the grounding member comprises a circumferential band comprising a section that approximates a hollow cylinder, the circumferential band having first and second opposing side edges.

32. The coaxial cable connector of claim 31, wherein the section that approximates a hollow cylinder comprises a cylindrical surface that extends to one of first and second opposing side edges and wherein the other of first and second opposing side edges extends away from the cylindrical surface.

33. The coaxial cable connector of claim 32, wherein the coaxial cable connector extends along a longitudinal axis and the cylindrical surface coextends with the tubular post along a length parallel to the longitudinal axis.
