Coaxial connector for coaxial cable having a corrugated outer conductor

The present invention is related to electrical connectors and more particularly to connectors for coaxial cable having a corrugated outer conductor. A coaxial connector () for a coaxial cable () having a corrugated outer conductor (), including one which is helically corrugated. An adapter () of the connector can include a crimpable sleeve () within which is a bushing () initially having an axial slot () of selected dimension. The inner surface () of the bushing is fluted defining ridges and grooves (for cable of annular corrugation), or a continuous helical ridge () and associated groove () defining a thread of corresponding pitch, and general inner diameter permitting cable insertion. Upon full threading of the cable end into adapter (), crimp sleeve () is crimped thus closing axial slot () and stopping the crimp process to achieve a minimum desired inner diameter. The adapter may be a discrete subassembly and securable to a forward connector portion in modular fashion by complementary threaded flanges (). A connector () can also include one or more radial holes () extending to the cable-receiving region permitting solder () or conductive epoxy to be deposited following cable insertion, for mechanically and electrically connecting the rearward connector portion to the cable outer conductor () other than by crimping.
