ABSTRACT:
A terminal position assurance (TPA) system is disclosed in an electrical connector assembly. The system includes a dielectric connector housing having a plurality of terminal-receiving passages. A plurality of terminals are insertable in an insertion direction into the passages. A TPA device is insertable into the housing and includes a plurality of fingers movable in a direction transverse to the insertion direction into the passages when the TPA device is moved from a pre-load position allowing insertion of the terminals to a final position with the fingers projecting into the passages in engagement with the terminals. The TPA device includes a pair of flexible latch arms at opposite ends of the plurality of terminals for holding the TPA device in at least one of its pre-load and final positions. The flexible latch arms are flexible in the same direction of movement of the fingers into the terminal-receiving passages.
