Abstract
Abstract A zero insertion force socket for an electronic package comprises a cover (20) which is slidably mounted on a base (10). The cover has a package mounting surface (22) which defines a plane. A cam mechanism (30) which is operable for sliding the cover on the base is pivotable on an axis (36) that extends perpendicular to the plane of the package mounting surface.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A socket for an electronic package comprising: a base holding a plurality of contacts; a cover slidably mounted on the base, the cover having a package mounting surface defining a plane; and a cam mechanism which is operable for sliding the cover on the base, the cam mechanism including a cam plate which is connected by a pivot member to the base on an axis extending perpendicular to the plane, the cam plate having a slot and an inner edge of the cam plate along one side of the slot defines a first cam surface that is operably connected for moving the cover in a first direction, the cam plate having an outer edge which defines a second cam surface that is operably connected for moving the cover in a second direction.
Claim 2
Dependent Claim
