## Abstract

A coaxial cable-connector assembly includes a coaxial cable and a coaxial connector. The coaxial cable includes: an inner conductor having a termination end, the termination end including a bore; a dielectric layer that overlies the inner conductor; an outer conductor that overlies the dielectric layer having a termination end; and a jacket that overlies the outer conductor. The coaxial connector includes: an inner conductor body including a boss that encircles the termination end of the inner conductor and a longitudinal bore; an outer conductor body electrically connected with the termination end of the outer conductor; and an expansion member inserted into the bore of the termination end of the inner conductor, the expansion member being sized and configured to radially expand the termination end of the inner conductor into electrical contact with the boss of the inner conductor body.

## Claims

### Claim 1

A coaxial connector comprising:
an inner conductor body configured to mate with an inner conductor body of a mating coaxial cable jack, the inner conductor body further configured to be attached to a termination end of an inner conductor of a coaxial cable;
an outer conductor body configured to mate with the an outer conductor body of the mating coaxial cable jack, the outer conductor body further configured to be electrically connected with a termination end of an outer conductor of the coaxial cable;
wherein the outer conductor body further includes a radially inward lip, such that a gap is formed between the lip and an inner surface of the outer conductor body, and is configured to receive the termination end of the outer conductor of the cable residing within the gap; and
wherein the outer conductor body is configured to be crimped to the termination end of the outer conductor of the coaxial cable;
the connector in combination with the coaxial cable, the coaxial cable comprising:
the inner conductor having a termination end;
a dielectric layer that overlies the inner conductor;
the outer conductor that overlies the dielectric layer having a termination end, the termination end residing in the gap; and
a jacket that overlies the outer conductor.

### Claim 2 (depends on 1)
