Socket warpage reduction apparatus and method

Claim 2

A zero insertion force socket that provides a flat surface mount region for an electrical device, the socket comprising: a top plate adapted to provide a flat surface mount region, the top plate having a plurality of pin insertion apertures adapted to permit insertion of electrical pin connections from the electrical device, a base having a plurality of receptacles adapted to receive the pin electrical connections of the electrical device that extend through the apertures in the top plate and into the receptacles, the top plate is slidably mounted on the base, a cam mechanism is secured to the base and cooperates with the top plate to slide the top plate over the base between an open and closed position, a lever is coupled to the cam mechanism and is pivotally movable from an open position to a closed position to permit in the open position the insertion of the electrical pin connections of the electrical device through the top plate apertures and into the base receptacles, whereupon pivotal movement of the lever causes the top plate to move in relation to the base to a closed position, thereby causing the electrical pin connectors to be secured in the receptacles in the base, and the flat surface mount region includes a first groove in the top plate that is contiguous to the surface mount region, whereupon movement of the lever from the open to closed position causes the lever to securely engage the groove in the top plate to thereby ensure that the top plate and the surface mount region is flat and remains flattened in varying ambient environments.

Claim 7

A zero insertion force socket that may be actuated and provides a flat surface mount region for an electrical device, the socket comprising: a top plate adapted to provide a flat surface mount region, the top plate having a plurality of pin insertion apertures adapted to permit insertion of electrical pin connections from the electrical device, a base having a plurality of receptacles adapted to receive the pin electrical connections of the electrical device that extend through the apertures in the top plate and into the receptacles, the top plate is slidably mounted on the base, a cam mechanism is secured to the base and cooperates with the top plate to slide the top plate over the base between an open and closed position, a U-shaped lever is coupled to the cam mechanism at ends of legs of the U-shaped lever and is pivotally movable from an open position to a closed position to permit in the open position the insertion of the electrical pin connections of the electrical device through the plate apertures and into the base receptacles whereupon pivotal movement of the lever to the closed position causes the electrical pin connectors to be secured in the receptacles in the base, and the top plate is provided with a U-shaped groove such that the surface mount region for the electrical device is disposed within legs of the U-shaped groove to thereby cause, upon movement of the lever from the open to the closed position, the U-shaped lever to securely engage the U-shaped groove in the top plate and thereby ensure that the top plate and the surface mount region is flat and remains flattened in varying ambient conditions.
