Abstract

Abstract An electrical connector assembly for interconnecting a leadless integrated circuit element with a printed circuit board having conductive strips thereon. The connector assembly comprises an insulative housing member which is releasably mounted on the board and contains a plurality of compartments each receiving an electrical contact. Each contact is generally S-shaped. The upper portion of each contact engages a conductive pad on the bottom of the leadless integrated circuit element while the lower portion of the contact extends across an aperture in the bottom of the housing member to contact a conductive strip on the printed circuit board. The free end of the upper portion of each contact extends into a recess in the wall of the housing to retain the contact therein.
