Abstract: An electrical connector system including an electrical female terminal an electrical contact portion for making electrical contact with either a round or square type male pin with chamfered corners. The contact portion including first, second and third finger each having a first end connected to a bridge and the second finger having a first end connected an outer barrel portion, and the first and third fingers having free ends. The electrical contact portion is received in and enclosed by the outer barrel portion and so that the other barrel portion has an open end to allow a male pin to be inserted therein and to make electrical contact with the first, second and third fingers. The terminal is a one piece tangless female terminal.

Abstract: An electric connector comprising an outer casing; a terminal block housed inside the casing and having a number of through cavities arranged in two parallel rows adjacent to the lateral walls of the terminal block; and a number of electric terminals housed inside respective cavities and retained therein by respective primary retaining means and by secondary retaining means consisting of a pair of movable elements integral with the lateral walls of the terminal block, connected to the terminal block by an elastic hinge, and having a number of teeth cooperating, in an assembly position, with respective electric terminals; snap-on means being provided for mutually engaging the lateral walls of the terminal block and the movable elements for maintaining the movable elements stably in the aforementioned assembly position.
