Abstract:

A spring wire formed tulip contact comprises cylindrical male and female members. The female member is formed by placing a plurality of spring wire fingers around the outer circumference of a cylindrical stud member in such a manner that the plurality of fingers extend axially outward from the stud to form a female contact sleeve. Each of the plurality of fingers are bent axially inward with respect to the stud in order that the innermost diameter of the female contact sleeve is smaller than the outer diameter of the male contact member. The plurality of fingers are held in firm electrical and mechanical contact with the stud member by a cylindrical retaining ring.
