Abstract

A connector having a conductively coated member is provided, wherein the connector comprises a connector body capable of sealing and securing a coaxial cable, and further wherein the conductively coated member, such as an O-ring, physically seals the connector, electrically couples the connector and the coaxial cable, facilitates grounding through the connector, and renders an electromagnetic shield preventing ingress of unwanted environmental noise.

Claims

1. A connector for coupling an end of a coaxial cable and for facilitating electrical connection with a male coaxial cable interface port, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a conductive grounding shield, the conductive grounding shield being surrounded by a protective outer jacket, the connector comprising:

a connector body, configured to receive at least a portion of the coaxial cable;

a post, having a mating edge, the post configured to electrically contact the conductive grounding shield of the coaxial cable; and

a conductively coated member, configured to reside within a coupling member of the connector, the conductively coated member positioned to physically and electrically contact the mating edge of the post to facilitate grounding of the connector through the conductively coated member and the post to the cable when the connector is threadably advanced onto an interface port and to help shield against ingress of unwanted electromagnetic interference.

2. The connector of claim 1, wherein said post includes a first end and a second end, the first end configured to be inserted into the end of the coaxial cable around the dielectric and under the conductive grounding shield thereof, and the second end having a face including the mating edge.

3. The connector of claim 1, wherein the conductively coated member is an O-ring that is spraycoated with a conductive coating for conductively sealing and physically sealing the connector.

4. The connector of claim 1, wherein the connector body includes a first end and a second end, said first end configured to deformably compress against and seal a received coaxial cable.

5. The connector of claim 1, further including a fastener member, wherein the fastener member is sized and shaped to deform the first end of said connector body.

6. The connector of claim 1, wherein a conductive coating is applied to an outer surface of the conductively coated member.

7. The connector of claim 6, wherein the conductive coating applied to the outer surface of the conductively coated member is applied to only a portion of the conductively coated member.

8. A connector for coupling an end of a coaxial cable and for facilitating electrical connection with a male coaxial cable interface port, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a conductive grounding shield, the conductive grounding shield being surrounded by a protective outer jacket, the connector comprising:

a connector body, configured to receive at least a portion of the coaxial cable;

a post, having a mating edge, the post configured to electrically contact the conductive grounding shield of the coaxial cable; and

a conductively coated member, configured to reside within a coupling member of the connector, the conductively coated member positioned to physically and electrically contact an inner surface of the coupling member to facilitate electrical continuity between the coupling member and the post to help shield against ingress of unwanted electromagnetic interference.

9. The connector of claim 8, wherein said post includes a first end and a second end, the first end configured to be inserted into the end of the coaxial cable around the dielectric and under the conductive grounding shield thereof.

10. The connector of claim 8, wherein the conductively coated member is an O-ring that is spraycoated with a conductive coating for conductively sealing and physically sealing the connector.

11. The connector of claim 8, wherein the connector body includes a first end and a second end, said first end configured to deformably compress against and seal a received coaxial cable.

12. The connector of claim 8, further including a fastener member, wherein the fastener member is sized and shaped to deform the first end of said connector body.

13. The connector of claim 8, wherein a conductive coating is applied to an outer surface of the conductively coated member.

14. The connector of claim 13, wherein the conductive coating applied to the outer surface of the conductively coated member is applied to only a portion of the conductively coated member.

15. A connector for coupling an end of a coaxial cable and facilitating electrical connection with a male coaxial cable interface port, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a conductive grounding shield, the conductive grounding shield being surrounded by a protective outer jacket, the connector comprising:

a post having a mating edge, wherein at least a portion of the post resides within a connector body;

a coupling member positioned axially with respect to the post; and

means for conductively sealing and electrically coupling the post and the coupling member of the connector to help facilitate grounding of the connector, wherein the means for conductively sealing and electrically coupling physically and electrically contact the mating edge of the post.

16. A method for grounding a coaxial cable through a connector, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a conductive grounding shield, the conductive grounding shield being surrounded by a protective outer jacket, the method comprising:

providing a connector, wherein the connector includes a connector body, a post having a mating edge, and a conductively coated member positioned to physically and electrically contact the mating edge of the post to facilitate grounding of the connector through the conductively coated member and the post to the cable, when the connector is attached to an interface port;

fixedly attaching the coaxial cable to the connector; and

advancing the connector onto an interface port until electrical grounding is extended through the conductively coated member.

17. The method of claim 16, further including providing said connector, wherein said connector further includes a coupling member, and further wherein the conductively coated member electrically couples and physically seals the post and coupling member.

18. The method of claim 16, further including completing an electromagnetic shield by threading the nut onto the interface port.
