Fastening device

摘要

A fastening device is disclosed. The fastening device has a vertical protrusion for fastening. A horizontal portion and an indicator are used for seating. The horizontal portion extends from the vertical protrusion for providing a clue to indicate that the fastening device is seated correctly. In embodiments, the clue is a color or a texture. In embodiments, a bellow is used with elastomeric properties. When the right load and torque are applied, the bellow covers the horizontal portion such that the color and/or texture of a perspective directed at the horizontal portion appear to be changed.

主权项

1. A fastening device for a heat sink, comprising:
a vertical protrusion for fastening; a horizontal portion for seating which has an inner bore for receiving the vertical protrusion; and an indicator for seating that abuts both the vertical protrusion and the horizontal portion, the indicator configured to have a first seating state for an unachieved seating tightness threshold and a second seating state for an achieved seating tightness threshold; wherein the vertical protrusion has a body area which fits through the inner bore, has a head area wider than the body area, and is configured to fasten the heat sink to an apparatus; wherein the horizontal portion extends from the vertical protrusion and has a wall configured to abut the indicator in the second seating state; wherein the horizontal portion has a floor having a diameter greater than the indicator in the first seating state, the floor including a first distinguishing feature including a visual element configured to be hidden beneath the indicator in the second seating state.
