Electrical connector with a sliding flexible cantilever beam terminal retainer

An electrical connector body configured to retain an electrical terminal, comprising:

• a terminal cavity, that extends through the connector body from a first opening at an insertion end to a second opening at a mating end of the connector body and having a pair of sidewalls opposite one another and defining a vertical axis and a longitudinal axis;
• a rigid terminal lock nib that projects inward into the terminal cavity, from a first rigid wall to engage into one of the pair of sidewalls for retaining the electrical terminal in the connector body;
• a flexible cantilever beam that projects axially into the terminal cavity from a fixed end of the cantilever beam connecting to a second rigid wall, said cantilever beam located opposite the rigid terminal lock nib and configured to push the electrical terminal against the second rigid wall and into retaining engagement with the terminal lock nib;
• and
• a pair of support ridges projecting into the terminal cavity from sidewalls of the terminal cavity, wherein the cantilever beam defines a pair of lateral protrusions configured to contact the pair of support ridges and wherein the pair of support ridges are configured to restrict movement of the free end of the cantilever beam in the vertical axis and not in the longitudinal axis.
