Abstract

A receptacle terminal having a receptacle end for receiving a pin terminal, the receptacle end including a body portion from which opposed contact walls extend between similarly extending strut walls, the walls forming a forwardly disposed shroud portion where the contact walls are connected to adjacent strut walls. A cantilevered contact arm for engaging the pin terminal is struck from one of the contact walls, leaving an opening therein having a tab formed along one of the strut walls. The contact wall being deformed to bring the tab over the contact arm, whereby deflection of the contact arm is opposed by the strut wall providing increased strength.

Claims

1. A receptacle terminal comprising a receptacle end for receiving a terminal, the receptacle end including a body portion from which a contact arm extends between similarly extending transversely disposed strut walls, the walls being interconnected to form a forwardly disposed shroud portion the terminal being characterized in that a tab is formed in communication with the strut walls, the strut walls being deformed to create a buckle in the shroud to bring the tab over the contact arm, whereby deflection of the contact arm as the terminal is inserted is opposed by the strut wall.

2. The receptacle terminal of claim 1, characterized in that contact arms are struck from a support wall of the shroud, wherein the tab is part of the shroud.

3. The receptacle terminal of claim 1, characterized in that a pair of spaced apart tabs are formed to support the contact arm.

4. The receptacle terminal of claim 1, characterized in that the strut walls are closer together at the shroud portion than at the body portion.

5. The receptacle terminal of claim 1, characterized in that the contact arm has a free end that includes a tongue extending therefrom and the tab overlies the tongue, where an edge of the tab corresponded to a edge of the tongue before forming.

6. The receptacle terminal of claim 3, characterized in that a free end of the contact arm is struck from the shroud portion where the contact support wall is buckled bringing that portion of the contact support wall located at the shroud portion adjacent to where the free end is struck over the free end of the contact arm as the tab, whereby as the adjacent strut walls cooperate with the contact support wall at the shroud portion to oppose displacement of the free end of the contact arm.

7. The receptacle terminal of claim 1, characterized in that the contact arm is formed to have a free end closely disposed to the tab prior to insertion of the pin terminal.

8. The receptacle terminal of claim 1, characterized in that the buckle is disposed in front of the free end of the contact arm.

9. A receptacle terminal comprising a receptacle end for receiving a pin terminal, the receptacle end including a body portion from which opposed contact walls extend between similarly extending strut walls, the contact walls and the strut walls forming a forwardly disposed shroud portion were the contact walls are connected to adjacent strut walls, and a cantilevered contact arm for engaging the pin terminal being struck from one of the contact walls and leaving an opening therein characterized in that a tab is formed along one of the strut walls and the strut walls are closer together at the shroud than at the body portion so that the tab overlies the contact arm, whereby deflection of the contact arm is opposed by the strut wall.

10. A method of manufacturing a receptacle terminal;

comprising the steps of;

(a) forming a terminal blank having a body portion from which a pair of contact walls extend forwardly, with strut walls running therealong, to a,forwardly disposed shroud portion and

(b) folding the terminal blank into a receptacle terminal with the contact walls oriented in an opposing manner and extending forwardly with the strut walls running therealong;

where between the steps of forming and folding the method is characterized by the steps of;

(c) striking a cantilevered contact arm from one of the contact walls of the terminal blank;

(d) forming a tab connected to one of the strut walls of the terminal blank; and

(e) bending the strut wall inward to bring the tab over the contact arm.

11. The method of claim 10, characterized in that the bending of the strut walls is accomplished by buckling the contact wall.
