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.
Claims9
A female contact member adapted to engage a male contact member, comprising:
- a conductive stud member;
- a plurality of spring wire fingers having a circular cross-section, said fingers located adjacent the periphery of said stud member and extending from said stud member to form a female contact sleeve;
- means for retaining said fingers in said position adjacent the periphery of and extending from said stud member and for retaining said fingers in good electric contact with said stud member, the periphery of said stud member having a plurality of parallel, longitudinally extending grooves therein, each of said wire fingers being seated in respective ones of said longitudinally extending grooves in the periphery of said stud member.
A spring wire formed tulip contact including a generally cylindrical male contact member and a generally cylindrical female contact member;
- said female contact member comprising:
- a generally cylindrical stud member;
- a plurality of cylindrical spring wire fingers located adjacent to the periphery of said stud member and extending axially from the said stud member to form a female contact sleeve;
- said wire fingers being bent radially inward toward the central axis of said female contact sleeve such that the innermost radius of said female contact sleeve is smaller than the outer radius of said male contact member;
- means for retaining said fingers in said position adjacent to the periphery of and extending from said stud member and for retaining said fingers in good electrical contact with said stud member;
- said plurality of wire fingers being part of a single continuous wire, the free end of said fingers being free to flex outwardly without any restraint other than their inherent spring characteristic;
- the periphery of said stud member having a plurality of parallel, longitudinally extending grooves therein, each of said wire fingers being seated in respective ones of said longitudinally extending grooves in the periphery of said stud member.
