Abstract

Axially compressible, F-connectors for conventional installation tools for interconnection with coaxial cable include adaptations for establishing electrical continuity despite inadequate nut tightening. Each connector has a rigid nut, a post penetrating the nut, a tubular body, and an end cap. The conductive post coaxially extends through the connector, linking the nut and body. A post end penetrates the coaxial cable. The connector may have a circumferential groove defined in the end cap mounting an annular D-ring which tensions contact between the post and nut. The connector may comprise a continuity coil seated within a post groove in spring-loaded contact with the nut and the post for promoting continuity. The connector may comprise a pressure spring and an O-ring seated within a post groove in spring-loaded contact with the nut for promoting continuity.

Claims

1. A compressible coaxial connector comprising:

a nut adapted to threadably fasten the connector, the nut comprising an interior;

an elongated, hollow post mechanically coupled to said nut, the post comprising a portion that internally abuts the nut;

a hollow, tubular body coaxially disposed over said post, the body comprising a circular groove facing the nut;

a tubular end cap adapted to be slidably coupled to said body; and

,

a D-ring disposed within said body groove for contacting and grasping the nut in assembly to tension contact between the nut and the post.

2. The connector as defined in claim 1 wherein the connector post comprises a groove, and a continuity coil comprising a spring formed into a circle is disposed within the post groove for contacting the nut interior.

3. The connector as defined in claim 1 wherein the connector post comprises a groove, and a continuity coil comprising a spring formed into a circle is disposed within the post groove for contacting the nut interior.

4. A compressible F-connector adapted to be electrically and mechanically attached to the prepared end of a coaxial cable for thereafter establishing an electrical connection to an appropriate threaded socket, the coaxial cable comprising an outer conductive braid, said F-connector comprising:

a nut adapted to be threadably coupled to said socket, the nut comprising an interior;

an elongated, hollow post having a flange and an end adapted to be inserted into said prepared cable end and a groove;

a hollow tubular body coaxially disposed over said post;

an end cap adapted to be slidably coupled to said body; and

,

a continuity coil disposed within said post groove for establishing a ground path between said post and said nut.

5. The connector as defined in claim 4 wherein the body comprises a circular groove facing the nut and an O-ring disposed within said body groove for contacting the nut in assembly to tension contact between the nut and the post.

6. The connector as defined in claim 5 wherein the O-ring comprises a D-ring.

7. A compressible F-connector adapted to be electrically and mechanically attached to the prepared end of a coaxial cable for thereafter establishing an electrical connection to an appropriate threaded socket, the coaxial cable including an outer conductive braid, said F-connector comprising:

a nut adapted to be threadably coupled to said socket, the nut including an interior;

an elongated, hollow post having a flange and an end adapted to be inserted into said prepared cable end;

a hollow tubular body coaxially disposed over said post, the body including a circular groove facing the nut;

an end cap adapted to be slidably coupled to said body; and

,

a pressure spring within said body groove for pressuring the nut and establishing a ground path between said post and said nut.

8. The connector as defined in claim 7 wherein the connector comprises a circular O-ring facing the nut and disposed within said body groove adjacent said pressure spring for contacting the nut in assembly to tension contact between the nut and the post.

9. The connector as defined in claim 7 wherein the connector comprises a circular O-ring facing the nut and disposed within said body groove adjacent said pressure spring for urging the O-ring to contact the nut.

10. The connector as defined in claim 7 wherein a D-ring for contacting the nut in assembly is disposed within said body groove adjacent said pressure spring to tension contact between the nut and the post.

11. A compressible F-connector adapted to be electrically and mechanically attached to the prepared end of a coaxial cable for establishing an electrical connection to a mating connector, the coaxial cable including an outer conductive braid, and the F-connector comprising:

a nut including an interior, the nut adapted to be threadably coupled to said mating connector;

an elongated, hollow post having a) a flange and an end adapted to be inserted into said prepared cable end, b) a forward groove adjacent to the flange, and c) a rear shoulder adjacent to the forward groove;

a hollow tubular body coaxially disposed over said post;

an end cap adapted to be slidably coupled to said body;

a continuity coil disposed within said forward groove for establishing a ground path between said post and said nut; and

,

an O-ring seated upon said rear shoulder establishing an environmental seal between said post and said nut.

12. The connector as defined in claim 11 wherein the continuity coil is in contact with both the post and the nut.

13. A compressible coaxial connector comprising:

a nut adapted to threadably fasten the connector;

the nut including an interior and a shoulder, said shoulder including a forward surface and a rearward surface;

an elongated, hollow post mechanically coupled to said nut, the post including a flange that abuts the nut shoulder forward surface;

a hollow, tubular body coaxially disposed over said post, the body including a circular groove facing the nut and adjacent to the nut shoulder rearward surface;

a tubular end cap adapted to be slidably coupled to said body;

an O-ring disposed within said body groove; and

,

wherein said O-ring contacts the nut only at the shoulder rearward surface to bias the nut shoulder forward surface into contact with the post flange.

14. The connector as defined in claim 13 wherein the O-ring comprises a D-ring.
