Abstract

A post-less coaxial cable connector includes a body, a shell, a compression ring, and a coupling portion. The shell has a collapsible groove that, when the post-less coaxial cable connector is axially compressed, collapses and engages the coaxial cable. This provides pull strength and electrical communication in the post-less coaxial cable connector. The compression ring has projections, that when the post-less coaxial cable connector is axially compressed, engage the coaxial cable jacket, providing sealing at the back end and rotation torque.

Claims

1. A post-less 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 post-less coaxial cable connector comprising:

a body having an internal surface extending between front and rear ends of the body, the internal surface defining a longitudinal opening, and a collapsible groove disposed between the front and rear ends;

a shell having an outer surface and an internal surface, the internal surface defining an opening through the shell, the internal surface slidingly engaging at least a portion of the rear end of the body; and

a compression ring disposed within the shell and engaging the rear end of the body, the compression ring having an internal surface and at least a portion of the internal surface having projections disposed around at least a portion thereof,

wherein upon compression of the post-less coaxial cable connector the projections of the compression ring engage the jacket of the coaxial cable to prevent rotation of the coaxial cable relative to the post-less coaxial cable connector and a portion of the body comprising a portion of the collapsible groove is compressed radially inwardly to engage the outer conductor of the coaxial cable.

2. The post-less coaxial cable connector according to claim 1, wherein upon compression of the post-less coaxial cable connector, the shell pushes the compression ring against the rear end of the body, causing the collapsible groove to be compressed axially and a portion thereof to engage the outer conductor before the compression ring is compressed radially inwardly to engage the outer jacket of the coaxial cable.

3. The post-less coaxial cable connector according to claim 1, further comprising a coupling portion rotatably engaging the front end of the body.

4. The post-less coaxial cable connector according to claim 3, further comprising an elastic ring disposed in an opening of the coupling portion to seal the front end of the post-less coaxial cable connector.

5. The post-less coaxial cable connector according to claim 1, wherein the internal surface of the compression ring has projections disposed around a circumference thereof.

6. The post-less coaxial cable connector according to claim 1, wherein the collapsible groove is disposed in an outer surface of the body.

7. The post-less coaxial cable connector according to claim 2, wherein the compression ring and shell seal the rear end of the post-less coaxial cable connector.

8. A combination of a coaxial cable and a post-less coaxial cable connector for terminating an end of the coaxial cable, 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 post-less coaxial cable connector comprising:

a body having an internal surface extending between front and rear ends of the body, the internal surface defining an longitudinal opening, and a collapsible groove disposed between the front and rear ends;

a shell having an outer surface and an internal surface, the internal surface defining an opening therein, the internal surface slidingly engaging the rear end of the body; and

a compression ring disposed within the shell and engaging the rear end of the body, the compression ring having an internal surface and at least a portion of the internal surface having projections disposed around at least a portion thereof,

wherein the coaxial cable extends through the shell, the compression ring, and the body, wherein the dielectric and the outer conductor terminate at the front end of the body, the inner conductor extends beyond a coupling portion and the jacket terminates about the rear end of the body.

9. The combination of a coaxial cable and a post-less coaxial cable connector according to claim 8, wherein upon compression of the post-less coaxial cable connector, the shell pushes the compression ring against the rear end of the body, causing the collapsible groove to be compressed axially and a portion thereof to engage the outer conductor before the compression ring is compressed radially inwardly to engage the outer jacket of the coaxial cable.

10. The combination of a coaxial cable and a post-less coaxial cable connector according to claim 8, further comprising a coupling portion rotatably engaging the front end of the body.

11. The combination of a coaxial cable and a post-less coaxial cable connector according to claim 8, further comprising an elastic ring disposed in an opening of the coupling portion to seal the front end of the post-less coaxial cable connector.

12. The combination of a coaxial cable and a post-less coaxial cable connector according to claim 8, wherein the internal surface of the compression ring has projections disposed around a circumference thereof.

13. The combination of a coaxial cable and a post-less coaxial cable connector according to claim 8, wherein the collapsible groove is disposed in an outer surface of the body.

14. The combination of a coaxial cable and a post-less coaxial cable connector according to claim 8, wherein the compression ring and shell seal the rear end of the post-less coaxial cable connector.

15. A method for connecting a coaxial cable to a post-less coaxial cable connector, the method comprising:

providing a post-less coaxial cable connector comprising a body having an internal surface extending between front and rear ends of the body, the internal surface defining an longitudinal opening, and a collapsible groove disposed between the front and rear ends, a shell having an outer surface and an internal surface, the internal surface defining an opening therein, the internal surface slidingly engaging the rear end of the body, and a compression ring disposed within the shell and engaging the rear end of the body, the compression ring having an internal surface and at least a portion of the internal surface having projections disposed around at least a portion thereof;

providing a 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;

preparing the coaxial cable by exposing a predetermined length of the center conductor and a predetermined length of the outer conductor, the outer conductor covering the underlying dielectric;

inserting the prepared coaxial cable into the shell, the compression ring, and the body, wherein the dielectric and the outer conductor terminate at the front end of the body, the inner conductor extends beyond the coupling portion and the jacket terminates about the rear end of the body;

axially compressing the post-less coaxial cable connector thereby causing the shell to push the compression ring against the rear end of the body, causing the collapsible groove to be compressed axially and a portion thereof to engage the outer conductor before the compression ring is compressed radially inwardly by the shell to engage the outer jacket of the coaxial cable.
