<p>A card guide which optimizes the flow of forced cooling air, provides for self alignment to a host motherboard and provides for integrated electro-static discharge (ESD) hazard mitigation, includes an elongated body having a groove disposed along a longitudinal axis of the body. The groove is adapted for receiving the edge of an inserted daughter card. The card guide further includes integral, arcuate inner and outer deflectors, which form a channel for redirecting incident air flow toward regions of the daughter card which would otherwise be blocked from the air flow. Extension deflector assemblies may be situated between card guides to extend the inner and outer deflectors so as to minimize air flow discontinuities in regions between daughter card positions. The end of the card guide that receives the daughter card houses an ESD clip. The ESD clip functions to dissipate static charge accumulated on the daughter card from a conductive strip disposed along the edge of the daughter card. The ESD clip further serves to dissipate accumulated static charge from a front panel attached to the daughter card, via a guide pin fixedly attached to the front panel. The end of the card guide proximate to the motherboard includes an alignment pin, which engages a corresponding aperture in the motherboard to properly register the card guide to the associated connector on the motherboard.</p> |
