ABSTRACT:
A mating terminal structure includes a generally box-shaped female terminal defining a receptacle with a flexible cantilevered contact beam formed from a bottom wall thereof. The beam includes a radiused contact portion. A male terminal is insertable into the receptacle in a given insertion direction (A) and includes a contact cam for deflecting the cantilevered contact beam and engaging the contact portion thereof. The contact cam has a leading ramp surface extending at a relatively small acute angle relative to the insertion direction for engaging the contact portion and gradually deflecting the cantilevered contact beam. The contact cam also has a trailing locking surface extending at a relatively larger acute angle relative to the insertion direction for providing locking interference between the contact portion of the cantilevered beam and the contact cam of the male terminal to thereby removably lock the male terminal to the female terminal.
