An electrical connector includes an electrical-terminal, a connector-housing, and a primary-lock-reinforcement. The electrical-terminal is configured to receive a corresponding electrical-terminal. The connector-housing defines a first-aperture, a second-aperture, and a body. The connector-housing is configured to receive the electrical-terminal through the first-aperture along a longitudinal-axis of the connector-housing. The body defines a cavity having a cantilevered terminal-lock. The cantilevered terminal-lock terminates proximate an outer-wall of the body. The cantilevered terminal-lock is configured to releasably retain the electrical-terminal. The outer-wall defines an orifice positioned proximate a terminus of the cantilevered terminal-lock. The primary-lock-reinforcement is configured to support the terminus of the cantilevered terminal-lock. When the primary-lock-reinforcement is moved from a pre-stage-position to a seated-position the terminus is inhibited from deflecting away from the electrical-terminal along a mating-axis thereby sealing the orifice.
