Abstract
Abstract A storage unit for an array of modular assemblies, such as disk drives, includes a cabinet having an array of rectangular cavities open toward the front, each for receiving an assembly carrier drawer. Each carrier drawer has electrical connections for receiving an electrical assembly in the drawer. The rear of each drawer has an electrical connection panel for mating a receiving panel connected to the inside back of the cabinet, and associated with the electrical connection panels are pin-and-aperture locating and registering means for precisely aligning the carrier drawer for proper mating electrical contact with the back of the cabinet automatically as the carrier drawer is pushed fully into the cabinet. This enables disk drive maintenance to be performed quickly and efficiently by pulling out a carrier drawer and inspecting, repairing or replacing the modular assembly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
205 words
In an assembly, including a cabinet formed to have at least one drawer-receiving cavity, a drawer configured for removable insertion in the cavity, and at least a pair of connector parts respectively associated with the cabinet and the drawer, an alignment system to provide blind-matable connection of the connector parts to establish electrical connection therebetween when the drawer is inserted in the cavity, the alignment system comprising: a pair of mounting means, for respectively mounting each of the connector parts to the cabinet and the drawer at locations that place the connector parts in interconnecting engagement when the drawer is inserted in the cavity, each mounting means having formed therein at least a pair of apertures, each connector part being mounted on the mounting means and accurately positioned with respect to the apertures formed in the respective mounting means; alignment means respectively formed on the cabinet and the drawer, and being engageable with each other to align a portion of the cabinet to a portion of the drawer, the alignment means having extensions which are received by the apertures when the pair of mounting means are in place, thereby accurately positioning the connector parts with respect to their corresponding alignment means and with each other.
