Abstract

A memory module, a motherboard, and a latch assembly coupled to the memory module and the motherboard are described, the latch assembly including a connector coupled to the motherboard, a first lever coupled to the connector via a first pivot point, an load member extending through an opening in the first lever, a second lever coupled to the load member via a second pivot point, and a spring to bias the load member away from the opening in the first lever. The latch assembly may be used as a dual inline memory module (DIMM) retention assembly for compression mount technology (CMT) and land grid array (LGA) connector loading.

First claim

We claim:

1. A computing system comprising:
a memory module;
a motherboard; and
a latch assembly coupled to the memory module and the motherboard, the latch assembly including:
a connector coupled to the motherboard,
a first lever coupled to the connector via a first pivot point,
an L-shaped load member extending through an opening in the first lever,
a second lever coupled to the L-shaped load member via a second pivot point, and
a spring to bias the L-shaped load member away from the opening in the first lever, wherein the spring is located so as to coil around a portion of the L-shaped load member.

2. The computing system of claim 1 , wherein the L-shaped load member includes a protrusion extending away from the spring.

3. The computing system of claim 2 , wherein in a latched position, the first lever rotates toward the memory module and the spring engages the protrusion with a recess in the memory module.

4. The computing system of claim 1 , wherein in an open position, the second lever causes the L-shaped load member to compress the spring and the first lever rotates away from the memory module.

5. The computing system of claim 1 , wherein the connector is a land grid array connector.

6. The computing system of claim 1 , wherein the connector is a compression mount technology connector.

7. The computing system of claim 1 , wherein the first lever is an L-shaped lever and the second lever is a longitudinal lever.

8. A latch assembly comprising:
a connector;
a first lever coupled to the connector via a first pivot point;
an L-shaped load member extending through an opening in the first lever;
a second lever coupled to the L-shaped load member via a second pivot point; and
a spring to bias the L-shaped load member away from the opening in the first lever, wherein the spring is located so as to coil around a portion of the L-shaped load member.

9. The latch assembly of claim 8 , wherein the L-shaped load member includes a protrusion extending away from the spring.

10. The latch assembly of claim 9 , wherein in a latched position, the first lever rotates toward a memory module and the spring engages the protrusion with a recess in the memory module.

11. The latch assembly of claim 8 , wherein in an open position, the second lever causes the L-shaped load member to compress the spring and the first lever rotates away from a memory module.

12. The latch assembly of claim 8 , wherein the connector is a land grid array connector.

13. The latch assembly of claim 8 , wherein the connector is a compression mount technology connector.

14. The latch assembly of claim 8 , wherein the first lever is an L-shaped lever and the second lever is a longitudinal lever.
