Abstract:     A memory module socket requires a reduced insertion force because a notch engager on a levered handle engages a notch on the memory module and applies downward pressure. The notch engager is forced downward as the levered handle pivots about an axis, causing the downward force to be applied to the notch on a memory module, forcing the memory module into a memory module socket on an extender card that plugs into a memory module socket on a personal computer motherboard. An ejector arm is pushed downward by the levered handle during removal. An ejector foot inside the memory module socket is pivoted upward around an ejector pivot when the ejector arm is pushed downward. The upward pivoting ejector foot pushes upward on the inserted edge of the memory module, forcing the memory module out of the memory module socket. Both ejection and insertion forces can be reduced.

First Claim:
Show all 22 claims
    1. A memory module test socket comprising:

a memory module connector socket having a slot for receiving a connector edge of a memory module, the slot having metal contacts for contacting metal contacts by the connector edge of the memory module;

the memory module connector socket having a middle portion having the slot and having end portions on opposing sides of the middle portion;

a levered handle pivoting near the end portion of the memory module connector socket;

an axis of the levered handle, the levered handle pivoting around the axis in an insertion direction;

a notch engager on the levered handle, the notch engager positioned to engage a notch on an edge of the memory module when the memory module is inserted and the levered handle is pivoted in the insertion direction around the axis; and

wherein the notch engager exerts a downward force on the notch of the memory module when the levered handle is pivoted around the axis in the insertion direction, the downward force on the notch causing the memory module to be forced into the slot of the memory module connector socket,

whereby the memory module is forced into the slot by the notch engager on the levered handle being pivoted in the insertion direction.
