A coaxial cable-connector assembly, comprising: (a) a coaxial cable comprising a central conductor, an outer conductor, a dielectric layer interposed between the central conductor and the outer conductor, and a jacket overlying the outer conductor; and (b) a coaxial connector comprising: a central conductor extension configured to mate with a mating connector at one end and mated with the central conductor of the coaxial cable at a second opposite end; an outer conductor extension configured to mate with the mating connector at one end and attached via a solder joint to the outer conductor of the coaxial cable at a second opposite end; and a dielectric spacer positioned between and separating the central conductor extension and the outer conductor extension, the dielectric spacer further positioned adjacent the solder joint; and the dielectric spacer includes a narrower portion, the narrower portion encircling the central conductor extension, wherein a wider portion of the dielectric spacer defines side walls of a cavity between the central conductor extension and the outer conductor extension; characterized in that, the wider portion extends toward the cable such that the end of the outer conductor of the cable adjacent the solder joint abuts only the end of the wider portion to inhibit solder from flowing away from the solder joint and into the cavity.
