Abstract:
1. An electrical connector comprising: an electrical terminal; a housing member having the electrical terminal mounted therein, wherein the housing member comprises a deflectable latch which latches the electrical terminal inside the housing member; and a terminal position assurance (TPA) member movably mounted on the housing member, wherein the TPA member comprises a blocking section adapted to substantially prevent deflection of the deflectable latch and at least one polarization section, wherein the polarization section comprises a first polarizer and a second polarizer, wherein the first polarizer is adapted to allow proper mounting of the TPA member relative to the housing member in only one position, wherein the second polarizer is adapted to allow proper mounting of a mating electrical connector relative to the electrical connector in only one position, wherein the polarization section is formed at a side wall of the TPA member with a groove along an exterior side of the side wall and an inward protrusion formed at an interior side of the side wall at the groove, wherein the inward protrusion forms the first polarizer and the groove forms the second polarizer, and wherein the first and second polarizers are formed by a wall irregularity in the side wall of the TPA member such that the recess and protrusion are substantially longitudinally synchronized with each other.
