Abstract

A coaxial cable connector for coupling an end of a coaxial cable to a terminal is disclosed. The connector has a post assembled with a coupler. The post is adapted to receive an end of the coaxial cable and comprises a front end, an enlarged shoulder at the front end, and a plurality of contacting portions. The contacting portions are of monolithic construction with the post, collectively circumscribe the enlarged shoulder at the front end of the post, and extend in a generally perpendicular orientation with respect to a longitudinal axis of the connector. The coupler is rotatably attached to the post and comprises an internally projecting lip, having a forward facing surface, adapted to couple the connector to the terminal. The contacting portions are configured to contact the forward facing surface of the lip of the coupler.

Claims

1. A coaxial cable connector, comprising a body, a post, and a coupler wherein:

the post is adapted to receive an end of a coaxial cable;

the post comprises a front end positioned in a central passage of the coupler, an enlarged shoulder at the front end of the post, and a plurality of contacting portions;

the contacting portions are formable, integral to, and monolithic with the post, collectively circumscribe the enlarged shoulder at the front end of the post, and comprise radially projecting protrusions formed to a contour of the coupler such that the coupler shapes at least one of the plurality of contacting portions to a formed state when the coupler is assembled with the body and the post, establishing electrical continuity between the coupler, the post, and the body to provide RF shielding.

2. The coaxial cable connector of claim 1, wherein the contacting portions facilitate electrical continuity between the coupler, the post, and the body other than by use of a component unattached from or independent of the coupler, the post, or the body.

3. The coaxial cable connector of claim 1, wherein the contacting portions facilitate electrical continuity between the post and the coupler regardless of the tightness of the coupling of the connector to a terminal.

4. The coaxial cable connector of claim 1, wherein the contacting portions facilitate electrical continuity between the post and the coupler when the coaxial cable connector is loosened or disconnected from a terminal.

5. The coaxial cable connector of claim 1, wherein the post is press-fit to the body.

6. The coaxial cable connector of claim 1, wherein the at least one of the contacting portions functions as an integral shield to provide a stable ground path for and protect against the ingress of RF signals into the coaxial cable connector.

7. The coaxial cable connector of claim 1, wherein the coupler comprises a face portion that tapers and guides the at least one of the plurality of contacting portions to the formed state.

8. The coaxial cable connector of claim 1, wherein the at least one of the plurality of contacting portions has a multi-cornered configuration.

9. The coaxial cable connector of claim 1, wherein the at least one of the plurality of contacting portions has a tri-cornered configuration.

10. The coaxial cable connector of claim 1, wherein in the formed state, the at least one of the plurality of contacting portions has a partially arcuate shape.

11. The coaxial cable connector of claim 1, wherein in the formed state, the at least one of the plurality of contacting portions has an arcuate shape.
