Abstract

A coaxial cable connector having an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, and a jacket surrounding the outer conductor and used for coupling an end of a coaxial cable to an equipment connection port. The coaxial cable includes a coupler, a body, a post, and a biasing ring. The coupler is adapted to couple the coaxial cable connector to the equipment connection port. At least one of the coupler, the post, and the body has an integral, monolithic contacting portion to establish electrical continuity between at least two of the coupler, the body and the post. The biasing ring biases the contacting portion such that the electrical continuity is maintained regardless of the tightness of the coupling of the connector to the terminal.

Claims

1. A coaxial cable connector for coupling an end of a coaxial cable to a terminal, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, and a jacket surrounding the outer conductor, the connector comprising:

a coupler adapted to couple the connector to the terminal;

a body assembled with the coupler;

a post assembled with the coupler and the body, wherein the post is adapted to receive an end of a coaxial cable; and

a biasing ring positioned inside of the coupler,

wherein one of the coupler, the post, or the body comprises a monolithically formed contacting portion configured to establish electrical continuity between at least two of the coupler, the body, and the post,

wherein the monolithically formed contacting portion is flexible, formed monolithically with the coupler, the post, or the body, and at least partially encloses the biasing ring when the coaxial cable connector is assembled, and

wherein the biasing ring biases the monolithically formed contacting portion of one of the coupler, the post, or the body to another of the coupler, the post, or the body such that electrical continuity is maintained regardless of the tightness of the coupling of the connector to the terminal.

2. The coaxial cable connector of claim 1, wherein the monolithically formed contacting portion comprises a radially projecting protrusion.

3. The coaxial cable connector of claim 1, wherein the monolithically formed contacting portion forms in a rearward facing manner when the coaxial cable connector is assembled.

4. The coaxial cable connector of claim 1, wherein the monolithically formed contacting portion forms in a forward facing manner when the coaxial cable connector is assembled.

5. The coaxial cable connector of claim 1, wherein the monolithically formed contacting portion provides for electrical continuity from the outer conductor of the coaxial cable to the terminal regardless of the tightness or adequacy of the coupling of the coaxial cable connector to the terminal.

6. The coaxial cable connector of claim 1, wherein the biasing ring comprises conductive material.

7. The coaxial cable connector of claim 1, wherein the coupler comprises a front end, a back end, and a lip extending into a bore formed by the coupler, and the monolithically formed contacting portion is disposed forward of the lip of the coupler when the coaxial cable connector is assembled.

8. A coaxial cable connector for coupling an end of a coaxial cable to an equipment connection port, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, and a jacket surrounding the outer conductor, the connector comprising:

a coupler adapted to couple the connector to the equipment connection port;

a body assembled with the coupler, and

a post assembled with the coupler and the body, wherein the post is adapted to receive an end of a coaxial cable;

a biasing ring, and

a retainer inserted in the coupler and the body, wherein (i) the biasing ring is positioned around the retainer, (ii) the retainer comprises a contacting portion at least partially enclosing the biasing ring with the contacting portion being flexible, (iii) the biasing ring biases the contacting portion to the coupler, and (iv) the contacting portion is of monolithic construction with the retainer, and

wherein electrical continuity is established between the retainer and the coupler such that the electrical continuity between the retainer and the coupler is maintained regardless of the tightness of the coupling of the connector to the terminal.

9. The coaxial cable connector of claim 8, wherein the contacting portion comprises a radially projecting protrusion.

10. The coaxial cable connector of claim 9, wherein the contacting portion at least partially encloses the biasing ring when the coaxial cable connector is assembled.

11. The coaxial cable connector of claim 8, wherein the coupler comprises a front end, a back end, and a lip extending into a bore formed by the coupler, and the monolithically formed contacting portion is disposed forward of the lip of the coupler when the coaxial cable connector is assembled.

12. A coaxial cable connector for coupling an end of a coaxial cable to an equipment connection port, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, and a jacket surrounding the outer conductor, the connector comprising:

a coupler adapted to couple the connector to a terminal;

a body assembled with the coupler;

a post comprising a monolithically formed contacting portion that is flexible, the post assembled with the coupler and the body, wherein the post is adapted to receive an end of a coaxial cable; and

a biasing ring positioned inside of the coupler,

wherein (i) the biasing ring biases the monolithically formed contacting portion of the post to the coupler when the coaxial cable connector is assembled, (ii) the monolithically formed contacting portion at least partially encloses the biasing ring when the coaxial cable connector is assembled, and (iii) the monolithically formed contacting portion is adapted to establish electrical continuity between the post and the coupler-such that electrical continuity is maintained regardless of the tightness of the coupling of the connector to the terminal.

13. The coaxial cable connector of claim 12, wherein the monolithically formed contacting portion comprises a radially projecting protrusion.

14. The coaxial cable connector of claim 13, wherein the monolithically formed contacting portion forms in a rearward facing manner when the coaxial cable connector is assembled.
