A connector assembly includes an outer contact and a cavity insert. The outer contact has a mating segment, a terminating segment, and a middle segment therebetween. The mating segment is configured to engage a mating outer contact of a mating connector assembly. The terminating segment is configured to be terminated to a cable. The cavity insert surrounds the middle segment of the outer contact. The cavity insert has an overmold body. An interior surface of the overmold body engages an exterior surface of the outer contact and follows contours of the exterior surface along the middle segment.
