Abstract
A ZIF PGA socket assembly (1) includes a base housing (10) having a top surface (12) and a plurality of elongated cavities (14), and a corresponding number of contacts (100) each having a pair of elongated spaced arms (108, 110) disposed in respective cavities (14). A sliding plate (70) which designedly slidably moves on the top surface (12) of the base housing (10), has a plurality of orifices (74) therethrough in registration with the corresponding cavities (14) in the base housing (10) to not only admit conductive pins from a PGA component into the cavities (14) but also bias one arm (108) of each contact (100) to form an enlarged space between such pair of arms (108, 110) for zero insertion force for conductive pins of the PGA component when the sliding plate (70) is in an operation position. A cover (50) is mounted on the top of the sliding plate (70) for cooperation with the base housing ( 10) to sandwich the sliding plate (70) therebetween.
