Abstract

An example device in accordance with an aspect of the present disclosure includes a grip to secure the device to an expansion card. The grip includes an upper grip portion to receive a fastener, and a standoff formed by a lower grip portion. The standoff is to establish a standoff distance between the expansion card and the mainboard when the device is secured to the expansion card and fastened to the mainboard.

First claim

What is claimed is:

1. A device comprising:
a grip to secure the device to an expansion card based on a friction fit, wherein:
the grip includes an upper grip portion to receive a fastener; and
the grip allows a portion of the expansion card to extend into the device to create a thermal couple between the expansion card and a mainboard;

a shoulder to retain the fastener in the device while enabling the fastener to be operable while retained in the device to fasten the device to the mainboard; and
a standoff formed by a lower grip portion to establish a standoff distance between the expansion card and the mainboard when the device is secured to the expansion card and fastened to the mainboard.

2. The device of claim 1 , wherein:
the shoulder is rounded corresponding to supporting a fastening force generated by a head of the fastener; and
the lower grip is rounded to accommodate the shoulder.

3. The device of claim 1 , wherein the shoulder is to retain the fastener based on a captive orifice to receive a shaft of the fastener.

4. The device of claim 1 , wherein the upper grip portion is spaced from the lower grip portion to enable the fastener to directly contact the expansion card.

5. The device of claim 1 , further comprising a shelf at the grip to stabilize the fastener.

6. The device of claim 1 , wherein the upper grip portion is a pronged extension.

7. The device of claim 1 , wherein the upper grip portion is a rounded extension.

8. The device of claim 1 , wherein the grip provides the friction fit based on a spring force between the upper grip portion and the lower grip portion.

9. The device of claim 1 , further comprising an aligner extending laterally from the grip to orient the device relative to the expansion card based on contact with an edge of the expansion card.

10. The device of claim 1 , wherein the device is to align the fastener at a distance from an edge of the expansion card corresponding to a mounting hole in the mainboard to receive the fastener.

11. The device of claim 1 , wherein the shoulder is to contact the expansion card to provide heat transfer and electrical grounding between the expansion card and the mainboard.

12. A device comprising:
a grip to secure the device to an expansion card based on a friction fit, wherein:
the grip includes an upper grip portion to receive a fastener;
the grip includes a shelf to stabilize the fastener; and
the grip allows a portion of the expansion card to extend into the device to create a thermal couple between the expansion card and a mainboard; and

a standoff formed by a lower grip portion to establish a standoff distance between the expansion card and the mainboard when the device is secured to the expansion card and fastened to the mainboard, wherein:
the upper grip portion has first radius corresponding to an upper cutout of the expansion card; and
the lower grip portion has a second radius corresponding to a lower cutout of the expansion card.

13. A device comprising:
a grip to secure the device to an expansion card based on a friction fit, wherein:
the grip includes an upper grip portion to receive a fastener; and
the grip allows a portion of the expansion card to extend into the device to create a thermal couple between the expansion card and a mainboard; and

a shoulder to retain the fastener while enabling the fastener to be operable while retained in the device to fasten the device to mainboard;
a standoff formed by a lower grip portion, to establish a standoff distance between the expansion card and the mainboard when the device is secured to the expansion card and fastened to the mainboard; and
a fastener captively retained by a captive orifice of the shoulder.

14. The device of claim 13 , wherein the fastener is captively retained based on a fastener shaft having a varying diameter.

15. The device of claim 13 , wherein the fastener is captively retained while enabling the fastener a tolerance to slide along an axis of rotation of the fastener.
