ABSTRACT:
For mating with a tubular female contact 12, a male contact 10, has two cantilevered arms (16, 18) extending from its body portion 14. The arms are each formed of sheet metal and each has a convex mating surface near its tip which faces outwardly, away from the other arm. The arms may have equal or unequal lengths, may be displaced laterally in the plane of the sheet metal, and may be shaped so that the tips either contact or are spaced when mated. In a preferred embodiment, the ends of the arms have a complementary stepped configuration 50 to reduce the volume of the contact's mating portions; the resultant narrower end portions of the arms, as well as the convex mating surfaces further down on the arms, may both mate with the female contact, providing two points of contact on each arm.
