Abstract

A connector for a coaxial cable includes a connector body and a post having a flanged end as well as a coupling nut rotatably attached to the flanged end of the post. The flanged end of the post is defined by an open-ended port retaining portion having an exterior threaded surface that is engaged by respective internal threads of the coupling nut. The port retaining portion defines a locking collet that enables exterior ports of varying diameters to be engaged with and secured to the connector.

Claims

1. A connector for a coaxial cable, said connector comprising:

a post having a first end, a second end, and an exterior surface;

a connector body having a post mounting portion configured to mate with the exterior surface of the post;

a coupling nut rotatably attached to the first end of said post, said coupling nut including a set of internal threads, said first end of the post further including a open-ended port retaining portion defining a locking collet, at least an axial section of said port retaining portion including external threads engageable with the internal threads of said coupling nut, thereby enabling various sized external ports to be engaged with said connector.

2. A connector as recited in claim 1, wherein the second end of said post extends into a center passageway of said connector body and is axially secured therein.

3. A connector as recited in claim 1, wherein said connector is an F-type connector.

4. A connector as recited in claim 1, further including a compression member for securing a coaxial cable end within said connector body.

5. A connector as recited in claim 1, wherein said open-ended port retaining portion is made from an electrically conductive material such that electrical continuity is created and maintained when said external port is initially engaged therewith.

6. A connector as recited in claim 1, wherein said port retaining portion comprises a socket having a peripheral wall and cylindrical receiving cavity, said socket including a plurality of spring fingers defined by axial slots disposed in said peripheral wall.

7. A coaxial cable connector comprising:

a connector body including a hollow interior that is sized to receive a prepared coaxial cable end, wherein the connector body includes a post mounting portion;

a post having a pair of opposing ends in which one of said ends is sized to be fitted into said connector body for engaging said coaxial cable end for securement thereto, said post being rotatably and axially secured in relation to said connector body at said first end, said remaining end of said post including an open-ended port retaining portion, wherein the post mounting portion of the connector body is configured to mate with an exterior surface of the post; and

a coupling nut rotatably attached to the exterior of said open-ended retaining portion, said coupling nut including a set of interior threads for engaging external threads on said open-ended port retaining portion, said port retaining portion defining a locking collet that is configured for engaging an external interface port wherein rotation of said coupling nut in a tightening direction causes said collet to engage upon and secure said port.

8. A connector as recited in claim 7, wherein said open-ended port retaining portion comprises a socket, said socket having a peripheral wall and a cylindrical receiving cavity, said socket further including a plurality of circumferentially spaced axial slots.

9. A connector as recited in claim 7, wherein said connector is an F-type connector.

10. A connector as recited in claim 7, wherein said open-ended port retaining portion is made from an electrically conductive material.
