Abstract

In one embodiment, an apparatus includes a module for use in installing a heatsink, the module comprising a fastener, a first indicator member comprising a first visual indicator surface, and a second indicator member comprising a second visual indicator surface, the first and second indicator members defining an opening for receiving the fastener. The first visual indicator surface is visible when the fastener is not fully installed and the second visual indicator surface is visible when the fastener is fully installed. A method for installing the heatsink with the module is also disclosed herein.

First claim

What is claimed is:

1. An apparatus comprising:
a module for use in installing a heatsink, the module comprising:
a fastener;
a first indicator member comprising a first visual indicator surface; and
a second indicator member comprising a second visual indicator surface, the first indicator member and the second indicator member defining an opening for receiving the fastener,

wherein the first visual indicator surface is visible from a top view when the fastener is partially installed and the second visual indicator surface is visible when the fastener is fully installed.

2. The apparatus of claim 1 wherein the first visual indicator surface and the second visual indicator surface are different colors and only one of the first visual indicator surface and the second visual indicator surface is visible at a time.

3. The apparatus of claim 1 wherein said first indicator member comprises an indicator sleeve and said second indicator member comprises one or more resilient indicator pins received in the indicator sleeve.

4. The apparatus of claim 1 wherein said second indicator member is forced radially outward when the fastener is fully installed to expose said second visual indicator surface.

5. The apparatus of claim 1 wherein the fastener comprises a spring loaded screw.

6. The apparatus of claim 1 wherein the fastener comprises a spring loaded pushpin.

7. The apparatus of claim 1 , wherein the first indicator member is an indicator sleeve and the second indicator member extends upward from a base of the module and forms an inner sleeve received within the indicator sleeve.

8. The apparatus of claim 1 , wherein the first indicator member includes an indicator sleeve and the second indicator member includes at least one indicator pin.

9. The apparatus of claim 1 , wherein the module further comprises an outer sleeve configured to block the second visual indicator surface from view when the fastener is not fully installed.

10. An apparatus comprising:
a heatsink; and
a plurality of modules attached to the heatsink for installation of the heatsink; each of the plurality of modules comprising:
a fastener;
a first indicator member comprising a first visual indicator surface; and
a second indicator member comprising a second visual indicator surface;

wherein the first visual indicator surface is visible, from a top view, when the fastener is partially installed and the second visual indicator surface is visible when the fastener is fully installed.

11. The apparatus of claim 10 , wherein the first visual indicator surface and the second visual indicator surface are different colors and only one of the first visual indicator surface and the second visual indicator surface is visible at a time.

12. The apparatus of claim 10 wherein a head of the fastener forces said second indicator member into a position in which said second visual indicator surface is visible when the fastener is fully installed.

13. The apparatus of claim 10 wherein said second indicator member is forced radially outward when the fastener is fully installed to expose said second visual indicator surface.

14. The apparatus of claim 10 , wherein the first indicator member and the second indicator member are received in an outer sleeve and wherein the outer sleeve blocks the second visual indicator surface from view when the fastener is not fully installed.

15. The apparatus of claim 10 wherein the fastener comprises a spring loaded screw.

16. The apparatus of claim 10 wherein the fastener comprises a spring loaded pushpin.

17. The apparatus of claim 10 , wherein the first indicator member is an indicator sleeve and the second indicator member extends upward from a base of a respective module and forms an inner sleeve received within the indicator sleeve.

18. The apparatus of claim 10 , wherein the first indicator member includes an indicator sleeve and the second indicator member includes at least one indicator pin.

19. The apparatus of claim 10 , wherein each of the plurality of modules further comprises an outer sleeve configured to block the second visual indicator surface from view when the fastener is not fully installed.

20. An apparatus comprising:
a module for use in installing a heatsink, the module comprising:
a fastener;
a first indicator member comprising a first visual indicator surface; and
a second indicator member comprising a second visual indicator surface, the first indicator member and the second indicator member defining an opening for receiving the fastener,

wherein the first visual indicator surface is visible when the fastener is not fully installed and the second visual indicator surface is visible when the fastener is fully installed,
wherein the first indicator member and the second indicator member are received in an outer sleeve, and
wherein the outer sleeve blocks the second visual indicator surface from view when the fastener is not fully installed.
