Connector with integrated primary lock reinforcement and terminal position assurance

A connector assembly comprises a resilient primary lock for securing a wire terminal with a housing, a primary lock reinforcement (PLR) device, and a PLR actuator for moving the PLR device between pre- and fully-staged configurations. The PLR device is configured to move in response to contact by the PLR actuator as the housing components are mated together. The PLR actuator includes an elongated, tapered finger that wedges against the PLR device during housing mating. A method of reinforcing a primary lock of a connector assembly is also described.
