Abstract

A coaxial cable connector comprising: a connector body; a post engageable with the connector body, wherein the post includes a flange; a nut, axially rotatable with respect to the post and the connector body, the nut having a first end and an opposing second end, wherein the nut includes an internal lip, and wherein a second end portion of the nut corresponds to the portion of the nut extending from the second end of the nut to the side of the lip of the nut facing the first end of the nut at a point nearest the second end of the nut, and a first end portion of the nut corresponds to the portion of the nut extending from the first end of the nut to the same point nearest the second end of the nut of the same side of the lip facing the first end of the nut; and a continuity member disposed within the second end portion of the nut and contacting the post and the nut, so that the continuity member extends electrical grounding continuity through the post and the nut is provided.

Claims

1. A coaxial cable connector comprising:

a connector body;

a post, engageable with the connector body, wherein the post includes a flange;

a nut, axially rotatable with respect to the post and the connector body, the nut having

a first end configured for coupling to an interface port and an opposing second end, and

an internal lip, the internal lip having a first surface facing the first end of the nut and a second surface facing the second end of the nut; and

a continuity member, positioned along the post, the continuity member having

a post contact portion, the post contact portion positioned to contact the post, and

a nut contact portion, the nut contact portion positioned to contact the second surface of the internal lip of the nut, and

wherein, the continuity member enhances electrical grounding continuity through the post and the nut.

2. The coaxial cable connector of claim 1 further comprising a fastener member having a central passageway configured to compress an inner surface of the connector body against a coaxial cable positioned therein.

3. The coaxial cable connector of claim 1 further comprising a sealing ring positioned between the nut and the connector body, wherein the sealing ring is configured to prevent ingress of unwanted environmental contaminants into the connector.

4. The coaxial cable connector of claim 1, wherein the continuity member is generally disk-like.

5. The coaxial cable connector of claim 1, wherein the continuity member further contacts an end of the connector body.

6. The coaxial cable connector of claim 1, wherein the continuity member contacts the flange of the post.

7. The coaxial cable connector of claim 1, wherein the continuity member contacts the post at a position other than the flange.

8. A coaxial cable connector comprising:

a connector body;

a post, having at least a portion thereof residing within the connector body, wherein the post includes a flange;

a coupler, axially rotatable with respect to the post and the connector body, the coupler having

a first end configured for coupling to an interface port and an opposing second end, and

an internal lip, the internal lip having a first surface facing the first end of the coupler and a second surface facing the second end of the coupler; and

a continuity member, disposed axially rearward of the second surface of the internal lip of the coupler;

wherein at least a portion of the continuity member extends about an external surface of the connector body and resides axially rearward of the coupler between the coupler and the connector body.

9. The coaxial cable connector of claim 8 further comprising a fastener member having a central passageway configured to compress an inner surface of the connector body against a coaxial cable positioned therein.

10. The coaxial cable connector of claim 8 further comprising a sealing ring positioned between the coupler and the connector body, wherein the sealing ring is configured to help prevent ingress of unwanted environmental contaminants into the connector.

11. The coaxial cable connector of claim 8, wherein the continuity member facilitates enhanced prevention of RF ingress into the coaxial cable connector near the second end of the coupler.

12. The coaxial cable connector of claim 8, wherein the continuity member extends electrical continuity between the coupler and the connector body.

13. The coaxial cable connector of claim 8, wherein the continuity member resides between the coupler and the connector body, so that there is no contact between the coupler and the connector body.
