Connector including compressible ring for clamping a conductor of a coaxial cable and associated methods
A connector is for attachment to a coaxial cable having an inner conductor, an outer conductor, and a dielectric therebetween. The connector includes a connector housing defining a radially outer ramp to receive the outer conductor thereagainst and a back nut. A compressible ring compressibly clamps against the outer conductor opposite the radially outer ramp as the connector housing and back nut are engaged. The connector also includes a center contact to be coupled to the inner conductor and an insulator member in the connector housing for carrying the center contact and having a radially outer support portion to radially support the outer conductor opposite the compressible ring.

3. The connector of claim 1 wherein said compressible ring comprises an electrically conductive compressible ring having a polymer coating.
4. The connector of claim 1 wherein said clamping ring comprises a compressible coil spring having an axis coaxial with said connector housing.
5. The connector of claim 1 wherein said connector housing and said back nut include respective portions defining a positive stop when fully engaged.
6. The connector of claim 5 wherein said connector housing comprises a rearward end; wherein said back nut comprises a shoulder; and wherein said positive stop is defined by the rearward end and the shoulder.
7. The connector of claim 1 wherein said back nut includes a forward portion threadingly received with a rearward portion of said connector housing.
8. The connector of claim 1 further comprising at least one sealing ring carried within said back nut.
9. The connector of claim 8 wherein said back nut has a sealing ring cavity defined therein; wherein said at least one sealing ring comprises a sealing ring body and a retaining projection extending outwardly therefrom; and wherein said retaining projection of said sealing ring is received by the sealing ring cavity.
10. The connector of claim 1 wherein the back nut comprises a polymer composite back nut.
11. The connector of claim 1 wherein the outer conductor of the coaxial cable comprises a corrugated outer conductor.
12. The connector of claim 1 wherein the outer conductor of the coaxial cable comprises a smooth outer conductor.
