Method, apparatus, and system for a low-profile computer adapter card retainer plunger
View Patent ↗A method, apparatus, and system are disclosed for a planar adapter card retainer bracket that is removably attachable to a computer chassis and is formed with a plurality of plunger openings. Each plunger opening is configured to receive a respective adapter card retainer plunger. The adapter card retainer plunger is configured to extend from the bracket into the computer chassis to engage an edge of an adapter card thereby retaining the adapter card in a selected slot even if the adapter card is a low-profile adapter card.
1. An apparatus comprising:
an adapter card retainer plunger comprising a first edge configured to removably attach to a plunger opening of an adapter card retainer bracket and a second edge configured to engage an edge of an adapter card within a chassis to securely maintain the adapter card in a substantially fixed position with respect to the chassis; and
an attachment protrusion extending from the first edge of the adapter card retainer plunger and configured to slidably attach to the plunger opening of the adapter card retainer bracket.
2. The apparatus of claim 1 , wherein the adapter card is a low-profile adapter card.
3. The apparatus of claim 1 , wherein the attachment protrusion comprises a narrow neck portion and a head portion, wherein the narrow neck portion is narrower than the head portion of the attachment protrusion.
4. The apparatus of claim 3 , further comprising an engagement tab extending from the first edge of the adapter card retainer plunger and configured to engage an edge of a wide side of the plunger opening.
5. The apparatus of claim 4 , wherein the attachment protrusion and engagement tab are configured such that if the adapter card retainer plunger is installed in the adapter card retainer bracket, the attachment protrusion and engagement tab are substantially flush with the adapter card retainer bracket.
6. The apparatus of claim 4 , wherein the first edge of the adapter card retainer plunger is formed with a slit that separates the attachment protrusion and the engagement tab, the slit configured to enable a flexible deflection of the engagement tab.
7. The apparatus of claim 4 , wherein the engagement tab is substantially flexible with respect to the attachment protrusion such that compression of the engagement tab causes a retaining force to be applied to the edge of the wide side of the plunger opening if the adapter card retainer plunger is installed into the adapter card retainer bracket.
8. The apparatus of claim 1 , wherein the second edge of the adapter card retainer plunger is opposite the first edge of the adapter card retainer plunger and is configured to reach a predefined distance from the first edge of the adapter card retainer plunger, the predefined distance corresponding to a distance from the adapter card retainer bracket to an edge of the adapter card that is nearest to the adapter card retainer bracket.
9. The apparatus of claim 1 , wherein the adapter card retainer plunger comprises a plastic material.
10. A system comprising:
an adapter card retainer bracket having a plurality of plunger openings formed therein, the adapter card retainer bracket configured to removably attach to a chassis, the chassis configured to house an adapter card; and
an adapter card retainer plunger comprising a first edge configured to removably attach to a plunger opening of the adapter card retainer bracket and a second edge configured to engage an edge of an adapter card within a chassis to securely maintain the adapter card in a substantially fixed position with respect to the chassis.
11. The system of claim 10 , further comprising an attachment protrusion extending from the first edge of the adapter card retainer plunger and configured to slidably attach to a narrow side of the plunger opening of the adapter card retainer bracket, the attachment protrusion comprising a narrow neck portion and a head portion, wherein the narrow neck portion is narrower than the head portion of the attachment protrusion.
12. The system of claim 11 , further comprising an engagement tab extending from the first edge of the adapter card retainer plunger and configured to engage an edge of a wide side of the plunger opening, the engagement tab configured to align with the attachment protrusion.
13. The system of claim 12 , wherein the attachment protrusion and engagement tab are configured such that if the adapter card retainer plunger is attached to the adapter card retainer bracket, the attachment protrusion and engagement tab are substantially flush with the adapter card retainer bracket.
14. The system of claim 12 , wherein the first edge of the adapter card retainer plunger comprises a slit that separates the attachment protrusion and the engagement tab, the slit configured to enable flexible movement of the engagement tab.
15. The system of claim 12 , wherein the engagement tab is substantially flexible with respect to the attachment protrusion such that compression of the engagement tab causes a retaining force to be applied to the edge of the wide side of the plunger opening if the adapter card retainer plunger is installed into the adapter card retainer bracket.
16. The system of claim 10 , wherein the second edge of the adapter card retainer plunger is opposite the first edge and is configured to have a predefined distance from the first edge of the adapter card retainer plunger, the predefined distance corresponding to a distance from the adapter card retainer bracket to the edge of the adapter card.
17. The system of claim 10 , wherein the chassis has a width defined in a direction substantially orthogonal to the adapter card retainer bracket and parallel to the installed adapter card that is in the range of 12.5 to 13.34 centimeters.
18. A method comprising:
forming an adapter card retainer plunger comprising a first edge configured to removably attach to a plunger opening of an adapter card retainer bracket and a second edge configured to engage an edge of an adapter card within a chassis to securely maintain the adapter card in a substantially fixed position with respect to the chassis; and
forming an attachment protrusion extending from the first edge of the adapter card retainer plunger and configured to slidably attach to a narrow side of the plunger opening of the adapter card retainer bracket.
19. The method of claim 18 , wherein the adapter card is a low-profile adapter card.
20. The method of claim 18 , wherein the attachment protrusion comprises a narrow neck portion and a head portion, wherein the narrow neck portion is narrower than the head portion of the attachment protrusion, and wherein the forming an adapter card retainer plunger comprises:
forming an engagement tab extending from the first edge of the adapter card retainer plunger configured to engage an edge of a wide side of the plunger opening, the engagement tab aligning with the attachment protrusion.
