The present disclosures relates to cable-connector assembly with heat-shrink sleeve. The coaxial cable-connector assembly comprises: (a) a coaxial cable having an inner conductor, a dielectric layer circumferentially surrounding the inner conductor, an outer conductor circumferentially surrounding the dielectric layer, and a polymeric jacket circumferentially surrounding the outer conductor; (b) a coaxial connector having a central contact attached to the inner conductor of the coaxial cable, an outer conductor body attached to the outer conductor of the coaxial cable, and a dielectric spacer interposed between the central contact and the outer conductor body; and (c) a heat shrink sleeve that conformably overlies a portion of the cable jacket and a portion of the outer body of the connector.
