Abstract

A system is disclosed that includes a flash module and a chassis. The flash module includes a top cover, a bottom cover, a printed circuit board, a capacitor, and a latch assembly. The latch assembly includes a housing having an opening and an inner cavity, a pull member, a reversing link, and a latch member. The chassis has an opening that is configured to receive the flash module. Also, the chassis includes a retaining pin coupled to the housing. The retaining pin protrudes into the inner cavity of the housing, and the second end of the latch member is configured to engage the retaining pin.

Claims

1. A system, comprising:

a flash module, comprising;

a top cover and a bottom cover;

a printed circuit board (PCB) comprising memory, solid state storage, a storage controller configured to manage the memory and the solid state storage, and at least one integrated connector;

a capacitor, wherein the capacitor is configured to power at least the storage controller when the flash module is disconnected from an external power source; and

a latch assembly, comprising;

a housing having an opening and an inner cavity formed therein;

a pull member having a first end and a second end, wherein the second end of the pull member is disposed within the housing;

a reversing link having a first end and a second end disposed within the housing, wherein the first end of the reversing link is pivotally coupled to the second end of the pull member and a portion of the reversing link is pivotally coupled to the housing; and

a latch member movable between a latched position and an unlatched position, the latch member having a first end and a second end disposed within the housing, wherein the latch member is pivotally coupled to the housing and the second end of the reversing link is configured to engage the first end of the latch member; and

a chassis having an opening formed therein, the opening configured to receive the flash module, the chassis comprising;

a retaining pin coupled to the housing, wherein the retaining pin protrudes into the inner cavity of the housing and the second end of the latch member is configured to engage the retaining pin.

2. The system of claim 1, wherein the first end of the latch member comprises an angled portion of the latch member configured to engage the second end of the reversing link such that movement of the second end of the reversing link in a direction away from the pull member causes the latch member to disengage from the retaining pin of the chassis.

3. The system of claim 1, wherein the second end of the latch member is an angled portion of the latch member comprising an angled surface and a flat surface.

4. The system of claim 3, wherein the angled surface of the second end of the latch member is configured to allow the latch member to slide over the retaining pin of the chassis, and wherein the flat surface of the second end of the latch member is configured to prevent the latch member from sliding over the retaining pin of the chassis.

5. The system of claim 1, wherein the housing comprises a return spring configured to engage the first end of the latch member, wherein the return spring of the housing provides a biasing force to bias the latch member to the latched position.

6. The system of claim 5, wherein overcoming the biasing force of the return spring by moving the first end of the pull member away from the housing causes the second end of the reversing link to engage the first end of the latch member and moves the latch member from the engaged position to the disengaged position.

7. The system of claim 1, further comprising a torsion spring disposed within the housing, wherein the torsion spring is configured to engage with the housing and the first end of the latch member, wherein the torsion spring provides a biasing force to bias the latch member to the latched position.

8. The system of claim 1, wherein moving the first end of the pull member toward the housing allows the latch member to slide over the retaining pin of the chassis.
