Female electrical contact

Claim 1

A female electrical contact for mating with a complementary male pin from only one direction, said contact comprising: a generally planar elongate body having a terminal portion at one end for electrical and mechanical termination to circuit board and a receptacle portion adjacent the other end; the receptacle portion providing means for receiving said complementary male pin and including a pair of base portions rigid with and spaced transversely of the body, said base portions extending generally perpendicularly from said body at an end of said body opposite said terminal portion and including generally abrupt end surfaces at the top thereof; said receptacle further including a pair of cantilevered arms of substantially equal length and in opposed relationship to each other with contact portions at their distal ends and each extending from one of said base portions towards said terminal portion, the cantilevered arms being bowed with their distal ends disposed inwardly of their proximal ends and the end of one arm being preloaded against the other arm, and the cantilevered arms being axially offset from each other in the longitudinal direction of insertion of the complementary male pin whereby the male pin engages the contact portions sequentially; and said body further including a second pair of upstanding walls rigid with and spaced transversely of the body, said second pair of walls extending generally perpendicularly from said body and including generally abrupt end surfaces at the top thereof, said second pair of walls being positioned between said receptacle and said terminal portion; whereby said female contact is dimensioned such that said cantilevered arms are positioned between a pair of generally U-shaped portions of said contact in order to rigidify said contact within an insulator.
