An embodiment of an electrical connector assembly includes a shell, a plurality of fixed conductors, and a potting container. The shell includes a plurality of walls extending in a first direction from a base having at least one opening. The base and the plurality of walls define a shell outer surface and a shell inner surface. The shell inner surface bounds an inner volume of the shell and has an inner shell profile. The plurality of fixed conductors project through the opening into the inner volume of the shell. The potting container includes an outer surface complementing the shell inner profile, and a cavity receives the fixed conductors through a slot in the base. A potting compound fills the cavity such that the potting compound completely surrounds the conductors.
