Abstract
A compression-type coaxial cable connector includes a post with at least one helical thread thereon. A typical coaxial cable includes a dielectric layer and a cable braid. The threaded post engages the coaxial cable between the cable braid and the dielectric layer, and can be installed by screwing the threaded post into the coaxial cable end.
Claims22
A coaxial cable connector for connecting to a coaxial cable, comprising:
- a connector body having a first end and a second end;
- a fastener interoperating with the first end of the body;
- a one-piece compression ring mounted to the second end of the body;
- an electrically conductive threaded post having a first end and a second end;
- the threaded post consisting of a post portion and a mandrel portion;
- at least one helical thread on the first end of the post, wherein the at least one thread assists in moving, with a twisting motion, the post between a braided layer of a coaxial cable and a dielectric layer of the coaxial cable;
- and
- the mandrel portion being adjacent the second end of the post;
- an electrical insulator fitted inside the body axially adjacent the mandrel portion of the post but not surrounding or inside any part of the post portion;
- and
- an electrically conductive pin part of which is fitted inside the insulator;
- wherein the conductive pin includes a collet structure at one end effective for receiving a center conductor of a coaxial cable;
- and
- wherein, when the compression ring is subjected to axial force moving the compression ring against a portion of the connector body, the interoperation between the compression ring and the connecter body forces a portion of the compression ring against an outside of the coaxial cable with no radial compression of the compression ring.

A method of manufacturing a cable connector, comprising the steps of:
- forming a connector body having a first end and a second end;
- forming a one-piece post and mandrel combination, consisting of a post portion and a mandrel portion, from an electrically conductive material, wherein the post portion includes a first end and a second end;
- forming at least one helical thread on the post portion;
- inserting the post portion into the body;
- forming or attaching a fastener on or adjacent to and interoperating with the first end of the body;
- and
- mounting a compression ring to the second end of the body;
- fitting an electrical insulator inside the body axially adjacent the mandrel portion of the combination;
- and
- fitting an electrically conductive pin partly inside the insulator;
- wherein the conductive pin includes a collet structure at one end effective for receiving a center conductor of a coaxial cable;
- wherein, when the compression ring is subjected to axial force moving the compression ring against a portion of the connector body, the interoperation between the compression ring and the connecter body forces a portion of the compression ring against an outside of the coaxial cable with no radial compression of the compression ring.
