Quick mount connector for a coaxial cable
A coaxial cable connector includes a body, a shell, a compression ring, and a coupling portion. The shell may have a collapsible groove that, when the 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 may have projections and a seal-forming rear end that, when the post-less coaxial cable connector is axially compressed, engage the coaxial cable jacket, providing sealing at the back end and anti-rotation torque.
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, a shell, and a compression ring without a post configured to engage the coaxial cable between the dielectric and outer conductor, wherein:
the body comprises a longitudinal opening extending between front and rear ends of the body;
the shell comprises an outer surface and an internal surface;
the internal surface of the shell defines an opening through the shell and engages at least a portion of the rear end of the body;
the compression ring is disposed within the opening of the shell between a portion of the body and a surface of the shell;
the compression ring comprises projections disposed around at least a portion of an internal surface of the compression ring and a rear end disposed rearwardly of the projections;
the projections are disposed around the internal surface of the compression ring so as to be pushed inwardly when the compression ring is forced inwardly against a coaxial cable; and
the rear end of the compression ring forms a seal with a jacket of a coaxial cable when the compression ring is forced inwardly against a coaxial cable.
2. The coaxial cable connector as claimed in claim 1 wherein the projections of the compression ring serve to engage an outer jacket of a coaxial cable to prevent rotation of the coaxial cable relative to the coaxial cable connector.
3. The coaxial cable connector as claimed in claim 1 wherein the projections are disposed completely around “a” circumference of the internal surface of the compression ring.
4. The coaxial cable connector as claimed in claim 1 wherein the projections are disposed partially around “a” circumference of the internal surface of the compression ring.
5. The coaxial cable connector as claimed in claim 1 wherein the projections extend along only a portion of “a” length of the compression ring.
6. The coaxial cable connector as claimed in claim 1 wherein:
the compression ring comprises a front end disposed against the rear end of the body; and
the rear end of the compression ring is disposed against the surface of the shell.
7. The coaxial cable connector as claimed in claim 6 wherein the projections are disposed forward of the rear end of compression ring.
8. The coaxial cable connector as claimed in claim 1 wherein:
the projections are disposed around a circumference of the internal surface of a front end of the compression ring; and
the seal-forming rear end of the compression ring defines a smaller inside diameter than the front end of the compression ring.
9. The coaxial cable connector as claimed in claim 8 wherein an axial transition from the front end of the compression ring to the seal-forming rear end of the compression ring comprises a radially inward diametrical step.
10. The coaxial cable connector as claimed in claim 1 wherein the connector is structurally configured such that, upon axial compression of the coaxial cable connector, the shell moves axially forward to cause the compression ring to be forced radially inward.
11. The coaxial cable connector as claimed in claim 10 wherein the axial compression is characterized by axial movement of the shell relative to the compression ring and movement of the projections radially inward to provide anti-rotation torque and movement of the seal-forming rear end of the compression ring radially inward to provide connector sealing.
12. The coaxial cable connector as claimed in claim 11 wherein the connector sealing is provided by the rear end of the compression ring and the shell.
13. A post-less coaxial cable connector comprising a body, a shell, and a compression ring without a post configured to engage a coaxial cable between a dielectric layer and outer conductor layer of the coaxial cable, wherein:
the body comprises a longitudinal opening extending between front and rear ends of the body;
the shell comprises an outer surface and an internal surface;
the internal surface of the shell defines an opening through the shell and engages at least a portion of the rear end of the body;
the compression ring is disposed within the opening of the shell between a portion of the body and a surface of the shell;
the compression ring comprises projections disposed around at least a portion of an internal surface of the compression ring and a rear end disposed rearwardly of the projections;
the projections are disposed around the internal surface of the compression ring so as to be pushed inwardly when the compression ring is forced inwardly; and
the rear end of the compression ring is structurally configured to cooperate with the shell to form a sealed end of the coaxial cable connector when the compression ring is forced inwardly.
14. The coaxial cable connector as claimed in claim 13 wherein the projections are disposed completely or partially around “a” circumference of the internal surface of the compression ring.
15. The coaxial cable connector as claimed in claim 13 wherein the projections extend along only a portion of “a” length of the compression ring.

the compression ring comprises a front end disposed against the rear end of the body;
the rear end of the compression ring is disposed against the surface of the shell; and
the projections are disposed forward of the rear end of compression ring.
17. The coaxial cable connector as claimed in claim 13 wherein:
the projections are disposed around “a” circumference of the internal surface of a front end of the compression ring; and
the seal-forming rear end of the compression ring defines a smaller inside diameter than the front end of the compression ring.
18. The coaxial cable connector as claimed in claim 17 wherein an axial transition from the front end of the compression ring to the seal-forming rear end of the compression ring comprises a radially inward diametrical step.
19. The coaxial cable connector as claimed in claim 13 wherein the connector is structurally configured such that, upon axial compression of the coaxial cable connector, the shell moves axially forward to cause the compression ring to be forced radially inward.
20. The coaxial cable connector as claimed in claim 19 wherein the axial compression is characterized by axial movement of the shell relative to the compression ring and movement of the projections radially inward to provide anti-rotation torque and movement of the seal-forming rear end of the compression ring radially inward to provide connector sealing.
