Abstract
Abstract A terminal for insertion into an integrated circuit panel board including an upper barrel portion in which a bore is formed, the outermost end of the upper barrel portion being countersunk to define a tapered entry for the bore; an inner member defining an interior contact member being located within the bore adjacent to the tapered entry of the outer member, wherein the tapered entry forms an enlarged opening for leading a male element into the inner contact member for electrical engagement therein.

A Terminal for use in an integrated circuit panel board and for insertion into a bore formed in said panel board, an outer member constructed of electrically conductive material having an upper barrel portion in which a core is formed and a lower elongated shank portion that defines an exterior contact element, said outer member extending into the bore in said panel board wherein a portion of the upper barrel portion is located above the panel board, the uppermost end of said upper barrel portion that is located above the panel board being countersunk to define a tapered entry for the bore formed therein, and an inner member defining an inner contact member secured within the bore in the outer member, said inner contact member having a substantially hollow configuration and including a head portion that is located adjacent to the tapered entry of the upper barrel portion of said outer member and a plurality of spring fingers that project inwardly of the upper barrel portion, said head portion of the inner contact member being of constant outer diameter and being positioned in surface-to-surface contact with the adjacent inner wall of the bore of said outer member and having a countersunk portion formed on the uppermost edge thereof, the countersunk portion of said inner contact member having substantially the same taper as the countersunk outer end of said upper barrel portion and being aligned therewith to form substantially a continuation thereof and cooperating therewith to form an unobstructed tapered entry for a male contact, the spring fingers of said inner contact member being spaced inwardly from the wall of the bore in said barrel portion and receiving the male contact therebetween upon insertion of the male contact through the tapered entry defined by the aligned countersunk portions on the end of said upper barrel portion and said head portion of the innercontact member, wherein said spring fingers are flexed outwardly by said inserted male contact for establishing positive electrical communication therewith.
