Abstract

A connector having a conductive member is provided, wherein the connector comprises a connector body capable of sealing and securing a coaxial cable, and further wherein the conductive 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 facilitating electrical connection with a coaxial cable interface port having a conductive surface, 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 first end and a second end, the first end configured to be inserted into an end of the coaxial cable around the dielectric and under the conductive grounding shield thereof;

a connector body attached to and at least partially surrounding the post, said connector body and post defining a space for receiving the conduct grounding sheath of the cable;

a nut operatively attached proximate the second end of the post; and

a conductive member electrically engaged with the second end of the post, wherein said conductive member is adapted to physically contact the conductive surface of the interface port and facilitate grounding of the coaxial cable.

2. The connector of claim 1 wherein the conductive member is resiliently deformable and is compressed between the second end of the post and the conductive surface of the interface port.

3. The connector of claim 2 wherein the nut is comprised of a conductive material.

4. The connector of claim 2 wherein the nut has an internal surface that is threaded.

5. The connector of claim 3 wherein the conductive member electrically engages the internal surface of the nut.

6. The connector of claim 1 further comprising a fastening member which secures the conductive grounding sheath within the annular space.

7. The connector of claim 1 further comprising a second conductive member electrically engaging the connector body with the nut.

8. A connector for coupling an end of a coaxial cable, the coaxial cable having a center conductor surrounded by a dielectric, the dielectric being surrounded by a conductive grounding sheath, the conductive grounding sheath being surrounded by a protective outer jacket, said connector comprising:

a post having a first end and a second end, the first end configured to be inserted into an end of the coaxial cable around the dielectric and under the conductive grounding shield thereof;

connector body operatively attached to said post defining a space between the post and the connector body for receiving the conductive grounding sheath;

a nut operably attached adjacent the second end of the post; and

a compressible conductive member located at the second end of the post, wherein said conductive member the facilitates grounding of the coaxial cable.

9. The connector of claim 8, further including a threaded nut, wherein the threaded nut is operably attached to said post.

10. The connector of claim 8, wherein the conductive member is an O-ring which completes a shield preventing ingress of electromagnetic noise into the connector.

11. The connector of claim 8, wherein in the conductive member facilitates grounding of the coaxial cable.

12. The connector of claim 8, further including a fastener member, wherein the fastener member is configured to operate on and deform the connector body sealingly compressing it against and affixing it to the coaxial cable.
