Coaxial cable-connector assemblies include: a coaxial cable having: an inner conductor having a termination end including a bore; a dielectric layer that overlies the inner conductor; and an outer conductor that overlies the dielectric layer having a termination end; a right angle coaxial connector including: an inner conductor body with a post configured to mate with the inner conductor body of a mating jack, the inner conductor body further including a receptacle that receives the termination end of the inner conductor such that the post is generally perpendicular to the inner conductor; an outer conductor body configured to mate with the outer conductor body of the mating coaxial cable jack and 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 sized and configured to radially expand the termination end of the inner conductor.
