ABSTRACT:
The disclosure of this specification shows an electrical connector pin which has been made out of a stamped piece of metal formed as a Y with a rectangular base portion thereof rolled into a roll pin for placing wire therein. The resultant pin has three arms spaced approximately one hundred and twenty degrees apart and comprise the support leg and the two downwardly extending arms. These three make contact with the inner wall of a suitable tubular mating socket. The two downwardly extending arms may contact and be held by an annular ledge which can be formed with an angle or in the form of a flange for holding the legs of the pin.
Another embodiment utilizes a tulip shaped pin in cross section. The tulip shape provides an S shaped compound curved resilient intermediate portion with outwardly extending terminal elements. The upper portion is free to compress into the mating tubular socket without forcing the extended lower portion of the two downwardly extended legs off of an annular retaining ledge. However, the pin can be removed if desired by a suitable tubular member that extends close to the retaining ledge, The tulip configuration allows a flexing thereof without substantial fatigue by avoiding gripping and attendant "ironing" of the pin into a smaller diameter than is required to hold a tubular connecting element that receives the pin. Finally, the three elements assure contact of pin to socket where only two elements may not suffice.
