Integrated circuit package connector

Claim 1

An electro-mechanical connector for connecting an integrated circuit package to an electronic system in a replaceable fashion; said connector including a frame having a plurality of electrical conductors mounted therein; and said frame being shaped to hold said integrated circuit package such that each electrical conductor of said plurality aligns with a corresponding lead in said integrated circuit package; wherein: each electrical conductor is comprised of an elongated planar piece of material having four bends respectively at lengths L 1 , L 2a , L 2b and L 3 along said conductor which make the maximum bending stress S in said conductor equal to S=k 1 F(L 1 ) and independently make the distance y by which said conductor deflects as said conductor pushes against said corresponding lead proportional to y=k 2 F(L 1 ) 3 +L 1 tan [k 3 FL 1 (L 2a +L 2b )] where F is the force by which said conductor pushes and k 1 , k 2 , and k 3 are constants; said lengths L 1 , L 2a , L 2b and L 3 being straight and of the same order of magnitude; a first one of said bends being a U-shaped bend which provides two legs; one of said legs having a second one of said bends of approximately 90° in a first direction at length L 2a from said U-shaped bend to thereafter provide a straight first leg portion of length L 1 for pushing against and making ohmic contact with a corresponding lead in said integrated circuit package; the other of said legs having a third one of said bends of approximately 90° in said first direction at length L 2b from said U-shaped bend which is longer than said length L 2a , and having a fourth one of said bends of approximately 90° at length L 3 further along its length in a direction perpendicular to said first direction to thereafter provide a second leg portion for making ohmic contact with said electrical system.
