ABSTRACT:
An electrical connector is provided with a transversely aligned terminal position assurance (TPA) component that is slidably insertable into a transverse keyway in the connector housing. The TPA component includes a plurality of flexing primary latches and a corresponding plurality of static secondary locks. The flexing primary latches are disposed to align with the terminal receiving cavities of the housing when the TPA component is in a pre-load position. The terminals can be inserted into the housing with the TPA component in this pre-load position such that the flexing primary latches at least temporarily retain the terminals in the housing. Upon complete insertion of all terminals the TPA component is indexed transversely into a final locked position such that the static secondary locks thereof positively engage each terminal to ensure complete insertion. A symmetrical front mating seal is configured to be held in the housing by suction to prevent separation during unmating.
