Cables with connector assemblies, filter units configured to releasably couple to the connector assemblies and related methods

A cable assembly, comprising:

• a coaxial cable comprising an inner conductor, an outer conductor, a dielectric between the inner conductor and the outer conductor and an outer jacket surrounding the outer conductor over a length of the coaxial cable, wherein the coaxial cable comprises a first end portion configured with an end portion of an inner conductor having an exposed free end, an end portion of an outer conductor terminating a distance rearward of the end portion of the inner conductor, and an end portion of a dielectric residing axially between the end portion of the inner conductor and the end portion of the outer conductor and terminating a distance rearward of the end portion of the inner conductor;
• and
• a connector assembly coupled to the first end portion of the coaxial cable, the connector assembly comprising:
• a first member comprising an open channel, the first member coupled to the end portion of the outer conductor with the free end of the inner conductor and the end portion of the dielectric extending through the open channel to reside forward of the first member and with an end of the end portion of the outer conductor terminating at or rearward of a forward end of the first member;
• and
• a second member residing rearward of the first member and comprising an open channel that slidably receives a rearwardly positioned portion of the first member and the first end portion of the coaxial cable and moves axially relative to the first member between installed and uninstalled positions.

A method of attaching a cable to a target device, comprising:

• providing a cable with a connector assembly on an end portion thereof, the connector assembly comprising a first member that is electrically conductive and coupled to an outer conductor and defining an open channel that surrounds an end portion of a dielectric and an end portion of an inner conductor with a free end of the inner conductor extending forward thereof whereby the first end portion of the cable defines first, second, third and fourth axially spaced apart stepped segments at the first end portion of the cable with decreasing respective different outer diameters, with the first segment defined by an outer jacket extending about the outer conductor, the dielectric and the inner conductor, with the second segment defined by the outer conductor surrounding the dielectric and inner conductor and extending forward of the first segment to the end portion of the outer conductor, with the third segment defined by the dielectric surrounding the inner conductor and extending forward of the second segment to the end portion of the dielectric, and with the fourth segment defined by the inner conductor extending forward of the third segment to the free end of the inner conductor, and also comprising a second member that is electrically conductive, positioned behind the first member, slidably coupled to the end portion of the cable;
• inserting the first member into a receiving channel of a target device;
• advancing the second member toward the first member in the receiving channel;
• and
• forcing the second member to abut the first member and press the first member against a stop surface in the receiving channel while the outer conductor is spaced apart from the stop surface to define an electrical ground connection with the target device.
