Abstract:
Examples of the disclosure enable a printed circuit board to be coupled to a chassis. In some examples, a coupling mechanism includes a first body including a head portion and a shaft portion that has an inner surface defining a channel. The coupling mechanism includes a second body including a head portion and a shaft portion. At least a part of the second body shaft portion is positionable within the channel. An outer surface of the second body shaft portion is sized to enable the second body shaft portion to expand radially or move laterally within the channel when the part of the second shaft portion is positioned within the channel. Examples of the disclosure enable the printed circuit board to be coupled to a chassis in low-profile, reduced-stress manner.
