Electrical connector with terminal position assurance member

An electrical connector comprising:

• a housing having a cable end and a mating end, the housing defining cavities that extend from the cable end parallel to a cavity axis, the cavities disposed side by side in a row and contain corresponding terminals therein, the housing further including a first wall and a second wall that define a terminal position assurance (TPA) slot therebetween, wherein the TPA slot extends across the cavities in the row and is open to the cavities;
• and
• a TPA member mounted to the housing within the TPA slot, the TPA member having a front side that engages the first wall of the housing and a rear side that engages the second wall of the housing, the front and rear sides of the TPA member extending between top and bottom ends of the TPA member, the TPA member being movable relative to the housing between an unlocked position and a locked position along an actuation axis that is perpendicular to the cavity axis,
• wherein, when the TPA member is in the locked position, the bottom end is disposed within the cavities and an upper portion of the TPA member is disposed in the TPA slot of the housing between the first and second walls, a lower portion of the TPA member within the cavities engages respective back edges of the terminals to block movement of the terminals towards the cable end.
