ADJUSTMENT AND ALIGNMENT INTERCONNECT TECHNIQUE FOR DASDs

This article describes a progressive adjustment and alignment interconnect technique for direct access storage devices (DASDs), including diskette drives, hard files and like devices.

Referring to the drawings, Fig. 1 is an exploded perspective view of a personal computer (PC) frame showing the DASDs in relation to the frame and its receptacles for the DASDs. The alignment and interconnect functions are obtained by establishing appropriate dimensional relationships among the components shown, i.e., the DASD slide 7 attached to the underside of the DASD with four fasteners (not shown), DASD shelf 2, DASD cards 3 and 12, the system planar board 1 and a system base (not shown) and the DASD itself.

The following sequence describes how the above components are assembled and their key relationships. The system planar board 1 is located in X, Y and Z planes and attached to the system base. The DASD shelf 2 is then assembled over the planar board 1. It is positioned (X, Y and Z) and attached to the system base with mechanical fasteners 11. The DASD cards 3 and 12 are installed down through an opening in the DASD shelf where cards 3 and 12 plug into connectors 4 and 13, respectively, on the planar board. This positions the DASD card connectors 5 and 14 in the X and Z directions. Projections 6 and 15 on the DASD shelf 2 establish the vertical (Y plane) downstop position for the connectors on the DASD cards. The DASD assemblies ar...
