Abstract: A connector assembly can include a housing, a terminal retainer, and a terminal position assurance member. The terminal retainer can be removably coupled with the housing and define a primary retaining lock for an electrical contact assembly. The terminal retainer can cooperate with the housing to form a compartment that can receive the electrical contact assembly. The compartment can extend along a mating axis of the housing, with a first frontal opening and a rear opening spaced from one another along the mating axis. A portion of the first frontal opening can be elastically deformable such that a size of the first frontal opening is variable. The terminal position assurance member can be removably coupled with the housing to define a secondary retaining lock for the electrical contact assembly. The terminal position assurance member can be positioned to inhibit elastic deformation of the portion of the first frontal opening.
