Abstract

A protective cover for a dual inline memory module (DIMM) circuit card includes a pair of cover members for substantially containing the DIMM circuit card. The cover members are secured to opposite sides of the DIMM circuit card. The pair of cover members defines a socket-receiving channel between respective printed-circuit-board (PCB) mating faces of the cover members. The cover members includes a plurality of positioning features engaging the DIMM circuit card for positioning a portion of the DIMM circuit card within the socket-receiving channel.

Claims

1. A protective cover for a memory circuit card comprising:

a pair of cover members for substantially containing the memory circuit card;

said cover members being secured to opposite sides of the memory circuit card;

said pair of cover members defining a socket-receiving channel between a respective printed-circuit-board (PCB) mating face of said pair of cover members;

said pair of cover members including a plurality of positioning features;

said positioning features engaging the memory circuit card for positioning a portion of the memory circuit card within said socket-receiving channel.

2. A protective cover for a memory circuit card as recited in claim 1 wherein the memory circuit card includes a dual inline memory module (DIMM) circuit card.

3. A protective cover for a memory circuit card as recited in claim 2 wherein said cover members includes features for receiving and mechanically self-aligning with the DIMM circuit card.

4. A protective cover for a memory circuit card as recited in claim 3 wherein said features for receiving and mechanically self-aligning with the DIMM circuit card include plurality of respective aligned openings within said cover members and the DIMM circuit card.

5. A protective cover for a memory circuit card as recited in claim 4 wherein said cover members are secured to the DIMM circuit card by a plurality of screws received in said respective aligned openings within said cover members and the DIMM circuit card.

6. A protective cover for a memory circuit card as recited in claim 2 wherein said cover members includes features enabling alignment, installation, and removal of the DIMM circuit card from an associated printed circuit board (PCB).

7. A protective cover for a memory circuit card as recited in claim 6 wherein said features of cover members include latch-engaging mechanisms for aligning, and positioning the DIMM circuit card for mating engagement with a connector on the associated PCB.

8. A protective cover for a memory circuit card as recited in claim 6 wherein said latch-engaging mechanisms of cover members enable removing positioning the DIMM circuit card from the associated PCB.

9. A protective cover for a memory circuit card as recited in claim 1 wherein each of said pair of cover members is a unitary, molded member.

10. A protective cover for a memory circuit card as recited in claim 1 wherein said cover members are formed of a selected antistatic material.

11. A protective cover for a memory circuit card as recited in claim 1 wherein said cover members are formed of a selected electrostatic discharge (ESD) plastic material.

12. A protective cover for a memory circuit card as recited in claim 1 wherein said cover members are unitary, molded members formed of a selected electrically insulative material having electrically conductive material inserted into the selected electrically insulative material.

13. A protective cover for a memory circuit card as recited in claim 1 wherein said electrically conductive material includes a selected one of metal fiber, carbon fiber, ferrite core material, stainless steel fiber, and nickel-coated carbon fiber.

14. A protective cover for a memory circuit card as recited in claim 2 wherein said cover members provide electromagnetic interference (EMI) shielding for the DIMM circuit card.

15. A protective cover for a memory circuit card as recited in claim 1 wherein at least one of said cover members include a plurality of openings for ventilation.

16. A protective cover for a dual inline memory module (DIMM) circuit card comprising:

a pair of cover members for substantially containing the DIMM circuit card;

said cover members being secured to opposite sides of the DIMM circuit card;

said pair of cover members defining a socket-receiving channel between a respective printed-circuit-board (PCB) mating face of said pair of cover members;

said pair of cover members including a plurality of positioning features;

said positioning features engaging the DIMM circuit card for positioning a portion of the memory circuit card within said socket-receiving channel.
