A receptacle terminal connector comprising: a dielectric connector housing; a miniature receptacle terminal supported by the dielectric housing, the miniature receptacle terminal comprising a connection section for connection to a conductor and an opposing box-shaped mating section for mating with a complementary male terminal, the mating section comprising a body portion, wherein the body portion comprises a bottom wall, a top wall and two side walls; the body portion having a longitudinal insertion axis; a polarizing projection extending from only a portion of the top wall of the body portion of the miniature receptacle terminal, wherein during insertion of the miniature receptacle terminal within the dielectric connector housing, a terminal front stop located on the polarizing projection engages with a surface on the dielectric connector housing as the miniature receptacle terminal is fully inserted into the dielectric connector housing, thereby preventing the miniature receptacle terminal from being inserted any further into the dielectric connector housing; at least one contact beam cantilevered from a first location on the body portion, at least a portion of the contact beam extending at a first angle from the longitudinal insertion axis into the receptacle terminal wherein a free end portion of the contact beam has a first concave portion and an end edge; a stiffening beam cantilevered from a second location on the body portion and into the receptacle terminal, the first and second locations being separated by a selected distance between the first and second locations, at a second angle from the longitudinal insertion axis into the connector, the contact beam being positioned below the stiffening beam; the second angle is larger than the first angle; a flap extending into the miniature receptacle terminal wherein the flap extends further down into the mating section than the end edge of the contact beam; wherein the bottom wall of the body portion has a primary lock up surface and wherein a primary locking member of the dielectric connector housing engages with the primary lock up surface, wherein the top wall of the body portion has a secondary lock up surface for engaging the dielectric housing, and wherein the miniature receptacle terminal has a secondary locking member for insertion into an opening into the dielectric connector housing restricts movement of the miniature receptacle terminal within the dielectric connector housing upon engaging the secondary lock up surface as if force is put on the miniature receptacle terminal in the opposite direction of the insertion direction, wherein the opening is arranged within the connector housing covering the top wall of the inserted body portion and adjacent to the secondary lock up surface. a dielectric connector housing;
