Coaxial cable connector for corrugated cable
View Patent ↗A coaxial cable connector is provided for attachment to a corrugated coaxial cable. The coaxial cable connector includes a clamping member with at least two projections configured to engage the outer corrugated conductor where the corrugated conductor has a diameter that is the smallest. The coaxial cable connector also includes seals to protect the coaxial cable connector from the elements. An alternative embodiment includes a third projection to engage the outer corrugated conductor to provide support for the coaxial cable.
1. A coaxial cable connector for attachment to a corrugated coaxial cable, the coaxial cable comprising a center conductor, a dielectric layer surrounding the center conductor, and an outer corrugated conductor surrounding the dielectric layer, the coaxial cable connector comprising:
a rear outer body having a front end, a back end, an external gripping portion, and a longitudinal opening extending between the front end and the back end along a longitudinal axis;
a clamping member rotatably mounted within the longitudinal opening in the rear outer body from the front end thereof, the clamping member having an internal surface with at least two projections configured to engage the outer corrugated conductor where the corrugated conductor has a diameter that is the smallest;
a front body having a front end, a back end, an external gripping portion, and a longitudinal opening extending between the front end and the back end along a longitudinal axis;
an insulator disposed in the front body, the insulator having an opening therein coaxial with the longitudinal axis of the front body; and
a contact element disposed in the opening of the insulator, the contact element having a back end configured to engage the center conductor of the corrugated coaxial cable;
wherein the clamping member is secured within the longitudinal opening of the rear outer body by way of a free-rotating snap fit.
2. The coaxial cable connector according to claim 1 , wherein the at least two projections comprise radially inward projecting annular rings.
3. The coaxial cable connector according to claim 1 , wherein the at least two projections comprise three projections.
4. The coaxial cable connector according to claim 1 , wherein the center conductor of the coaxial cable is hollow and has an interior surface and the contact assembly makes physical and electrical contact with the interior surface of the center conductor.
5. The coaxial cable connector according to claim 1 , further comprising at least two seals configured to engage the corrugated coaxial cable when fully installed.
6. A combination of a corrugated coaxial cable and a coaxial connector, the coaxial cable comprising a center conductor, a dielectric layer surrounding the center conductor, an outer corrugated conductor surrounding the dielectric layer, and a jacket surrounding the outer corrugated conductor, the coaxial cable connector comprising:
a rear outer body having a front end, a back end, an external gripping portion, and a longitudinal opening extending between the front end and the back end along a longitudinal axis;
a clamping member rotatably mounted within the longitudinal opening in the rear outer body from the front end thereof, the clamping member having an internal surface with at least two projections engaging the outer corrugated conductor where the corrugated conductor has a diameter that is the smallest;
a front body having a front end, a back end, an external gripping portion, and a longitudinal opening extending between the front end and the back end along a longitudinal axis;
an insulator disposed in the front body, the insulator having an opening therein coaxial with the longitudinal axis of the front body; and
a contact element disposed in the opening of the insulator, the contact element having a back end engaging at least a portion of the center conductor of the corrugated coaxial cable;
wherein the clamping member is secured within the longitudinal opening of the rear outer body by way of a free-rotating snap fit.
7. The coaxial cable connector according to claim 6 , wherein the at least two projections comprise radially inward projecting annular rings.
8. The coaxial cable connector according to claim 6 , wherein the at least two projections comprise three projections.
9. The coaxial cable connector according to claim 6 , wherein the center conductor of the coaxial cable is hollow and has an interior surface and the contact assembly makes physical and electrical contact with the interior surface of the center conductor.
10. The coaxial cable connector according to claim 6 , further comprising at least two seals engaging the corrugated coaxial cable when fully installed.
11. The coaxial cable connector according to claim 10 , wherein at least one of the least two seals engages the jacket and at least one of the least two seals engages the outer corrugated conductor of the corrugated coaxial cable.
