ABSTRACT:
A terminal position assurance (TPA) system for an electrical connector which includes a dielectric housing having terminal-receiving passageways with latch shoulders formed therein. A terminal is insertable into a rear end of the passageway and includes an outwardly extending primary locking portion adapted to latch behind latch shoulders of the passageway. A TPA device is engageable with a forward mating end of the housing and includes a secondary locking portion insertable into a front end of the passageway to prevent unlatching of the primary locking portion from the latch shoulders. If the terminal is incompletely inserted into the passageway, the secondary locking portion of the TPA device comes in contact with the primary locking portion of the terminal to move the terminal rearwardly and therefore detects incomplete insertion of the terminals.
