Patent attributes
An electrical connector includes a housing, multiple blade terminals, and a terminal position assurance (TPA) device. The blade terminals are held within cavities of the housing. The blade terminals have two edge sides between two broad sides and a rib projecting from at least one of the two edge sides. The TPA device is coupled to the housing at a mounting end thereof and is movable relative to the housing between an unlock position and a lock position. The TPA device has a base plate that defines multiple terminal openings therethrough. The base plate includes ledges that jut out into the terminal openings. The ledges extend behind and align with the ribs of the corresponding blade terminals when the TPA device is in the lock position to retain the blade terminals within the housing by abutting against back shoulders of the ribs.
