Abstract: A connector assembly having a housing configured to hold a plurality of electric connections of different sizes is provided. The connector assembly includes a housing having a plurality of first through-holes and a plurality of second through-holes. The housing includes a plurality of first terminal housings and a plurality of second terminal housings. The first terminal housings are spaced apart from each other so as to define a first axial slot. The terminal positioning assurance includes a spacer configured to be inserted within the first axial slot so as to maintain a fixed spatial relationship between the first terminal housings, the spacer is closed by a terminal housing, so as to prevent water from infiltrating into the first through-holes.
