Abstract

A socket is to receive a memory module usable in a computing system. A latch is to retain the memory module seated in the socket. The latch is to generate a positive locking latch retention force to prevent removal of the memory module while the latch is in a latched position.

First claim

What is claimed is:

1. A computing system comprising:
a socket to receive a memory module; and
a latch pivotably joined to the socket via a latch pivot to retain the memory module seated in the socket;
wherein the latch includes a latch contact region to apply a latch retention force to the memory module, wherein the latch pivot is offset from the latch contact region to generate a positive locking latch retention force to prevent removal of the memory module while the latch is in a latched position, and
wherein the latch retention force is resolvable to a first component vector, along an axis between the latch contact region and the latch pivot, and a second component vector perpendicular to the first component vector and extending away from the latch.

2. The computing system of claim 1 , wherein the latch and socket are to interface with a dual in-line memory module (MINI).

3. The computing system of claim 2 , wherein the latch and socket are to interface with a low-profile memory module.

4. A system comprising:
a socket to receive a memory module usable in a computing system;
a latch to retain the memory module seated in the socket; and
a latch pivot to pivotably join the latch to the socket;
wherein the latch is to generate a positive locking latch retention force that is to increase in response to an unseating force of the memory module, to prevent removal of the memory module while the latch is in a latched position;
wherein the latch further con rises a latch contact region to apply the latch retention force to the memory module; and
wherein the latch pivot is offset from the latch contact region such that the latch retention force is resolvable to a first component vector, along an axis between the latch contact region and the latch pivot, and a second component vector perpendicular to the first component vector and extending away from the latch.

5. The system of claim 4 ,
wherein the latch pivot is offset from the latch contact region in a direction away from the latch and toward the socket.

6. The system of claim 4 , wherein the latch pivot is based on a pivot pin of the latch and a corresponding pivot hole of the socket, and the latch is to pivotably join the socket based on a snap-together assembly.

7. The system of claim 4 , wherein the latch pivot is based on a first pivot hole in the latch, and a second pivot hole in the socket, and the latch is pivotably joined with the socket based on a pivot pin passing through the first pivot hole and the second pivot hole.

8. The system of claim 4 , wherein the latch includes an extension to engage the memory module upon insertion to cause the latch to actuate to latch onto the memory module in the latched position; wherein the extension is to eject the memory module upon actuation of the latch from the latched position to an unlatched position.

9. The system of claim 4 , wherein the latch is to generate the latch retention force based on a positive latching torque acting about the latch pivot.

10. The system of claim 9 ,
wherein the latch pivot is offset from the latch contact region to cause the latch to apply the positive latching torque about the latch pivot toward the socket.

11. The system of claim 4 , wherein the latch includes a detention feature to provide a latch detention force to stabilize the latch in the latched position to engage the memory module.

12. The system of claim 11 , wherein the detention feature is to provide the latch detention force based on a spring force provided by the detention feature, independently of the latch retention force.

13. A method, comprising:
retaining a memory module seated in a socket of a computing system, based on a latch pivotably joined to the socket by a latch pivot, wherein the latch is movable between an unlatched position and a latched position, and the latch includes a latch contact region;
generating, by the latch; a positive locking latch retention force that is to increase in response to an unseating force of the memory module, to prevent removal of the memory module while the latch is in the latched position, wherein the latch retention force is resolvable to a first component vector a on an axis between the latch contact region and the latch pivot, and a second component vector perpendicular to the first component vector and extending away from the latch.

14. The method of claim 13 , further comprising applying the latch retention force to the memory module based on a latch contact region of the latch; and
applying the positive latching torque about the latch pivot toward the socket, based on the latch pivot being offset from the latch contact region.
