Abstract
Abstract A disk drive module adapted for use in a data processing system, the system including first and second disk drive module guide plates. The disk drive module comprises an elongated, generally rectangular frame. The top wall of the frame includes a fin slidably insertable into a groove formed on the second guide plate, and the bottom wall of the frame includes a T-bar slidably insertable into a channel formed on the first guide plate. The T-bar includes a detent which releasably engages a pawl formed in the channel for securing the T-bar within the channel. A 3.5 inch disk drive and a regulator card are mounted within the frame. The rear edge of the regulator card includes an edge connector which extends rearwardly beyond the frame a short distance. To ensure that the edge connector is properly guided into engagement with a corresponding electrical connector in the data processing system, the regulator card is mounted on the frame for movement in three directions. This is accomplished by mounting the regulator card on a side wall of the frame using bifurcated squeezable snaps inserted through oversized holes formed in the regulator card. Because the holes are oversized relative to the snaps, the card can move in the plane of the card. Each snap includes a tab which limits upward movement of the card. The distance from the tabs to the side wall is greater than the thickness of the card; therefore, the card can also move in a direction perpendicular to the side wall.
