An electrical connector assembly includes an electrical conductor, a cable support, a housing, and a cap. The cable support includes a retainer arm and a cable support protrusion. The housing includes a housing recess and a housing protrusion. The cable support protrusion of the cable support interacts with the housing recess on the housing to support the cable support within the housing. The cap includes a locking mechanism and a tab. The housing protrusion on the housing and the locking mechanism on the cap interact to selectively retain the cap on and release the cap from the housing, and the retaining arm of the cable support and the tab of the locking mechanism interact to selectively move the retaining arm into and out of engagement with the electrical conductor.
