Abstract

An enclosure is assembled from metal-plated rigid structural foam plastic components to house in minimal space in many hard disk drives. Major components, including the power supply, plug directly to a motherboard at the rear of the enclosure, eliminating internal cables. The parts fit together in snap-in fashion in such manner that the back will not close if parts are not installed properly. For ventilation, slots are formed in the sides and a central partition which permit air from fans on one side to flow laterally across all the disk drives and then out through slots in the opposite side. A side facing door permits easy access to all drives simultaneously for service and upgrade.

Claims

1. An enclosure for a plurality of disk drives comprising a chassis having an open side, said chassis having at least two parallel partitions each formed with a plurality of opposed disk drive guides positioned with spaces between adjacent guides equal to the thickness of a disk drive, said guides being positioned to engage edges of disk drives, and a motherboard in the side of said chassis opposite said open side having a plurality of electrical connectors positioned opposite said spaces to connect to the inner ends of disk drives supported by said disk drive guides, each said guide comprising an integral boss extending outward of one said partition, said bosses having parallel surfaces substantially perpendicular to said partitions, said bosses being spaced from each other a distance equal to the thickness of a disk drive, said surfaces comprising tracks for reception of disk drives for movement of said disk drives parallel to said partitions, a third partition parallel to and intermediate said first mentioned at least two parallel partitions formed on two sides with a plurality of opposed disk drive projections spaced to engage edges of disk drives, a slitted front panel for connecting means for detachably connecting said front panel to one said partition, said connecting means comprising apertured lugs extending inwardly of said front panel and a catch mounted on said chassis to fit into apertures of said lugs.

2. An enclosure according to claim 1 which further comprises a third partition parallel to and intermediate said first mentioned at least two parallel partitions formed on two sides with a plurality of opposed disk drive projections spaced to engage edges of disk drives.

3. An enclosure according to claim 1 in which said chassis and said partitions are formed of metal plated rigid structural foam, said foam comprising electrical grounding and EMI containment.

4. An enclosure according to claim 1 which further comprises interfitting bottom, top, side, and front metallic outer skin panels and detachable means for detachably connecting said skin panels to said chassis.

5. An enclosure according to claim 1 in which said chassis opposite said open side has a plurality of electrical connectors positioned opposite said spaces to connect to the inner ends of disk drives supported by said projections and a door having a metallic panel positioned to establish electrical contract with said chassis.

6. An enclosure according to claim 1 which further comprises a slitted front panel and connector means for detachably connecting said front panel to one said partition.

7. An enclosure according to claim 1 in which said chassis and said partitions are formed of metal plated rigid structural foam, said foam comprising electrical grounding and EMI containment and which further comprises a door for said open side, said door comprising a metallic panel positioned to establish electrical contact with said chassis.

8. An enclosure according to claim 1 which further comprises a slitted front panel and connecting means for detachably connecting said front panel to one said partition.

9. An enclosure according to claim 8 which further comprises means for spacing said front panel from said one said partition.

10. An enclosure according to claim 8 which further comprises a fan and means housing said fan, said means housing said fan fitting into an end of said chassis remote from said front panel, said fan being arranged to draw air through said slitted front panel across disk drives supported by said partitions.

11. An enclosure for a plurality of disk drives comprising a chassis having an open side, said chassis having at least two parallel partitions each formed with a flat surface and a plurality of projections extending outwardly of said flat surface, said projections being positioned with spaces between adjacent projections equal to the thickness of a disk drive, the distance between adjacent flat surfaces equal to the width of a disk drive, said projections being positioned to engage edges of disk drives, said projections being formed with elongated slots in said projections extending through said partitions and said projections for air passage across disk drives supported by said projections.

12. An enclosure for a plurality of disk drives comprising a chassis having an open side, said chassis having at least two parallel partitions each formed with a plurality of projections extending outwardly of said partitions, said projections being positioned with spaces between adjacent projections equal to the thickness of a disk drive, said projections being positioned to engage edges of disk drives, said projections being formed with elongated slots for air passage across disk drives supported by said projections, interfitting bottom, top, side, and front metallic outer skin panels, and detachable means for detachably connecting said skin panels to said chassis, at least one of said detachable means comprises a flexible apertured lug fixed to one said outer skin panel and a slanted slot in said chassis, said aperture being dimensioned such that after said lug is bent to extend down through said slot, said lug straightens relative to said slot.

13. An enclosure for a plurality of disk drives comprising a chassis having an open side, a motherboard opposite said open side, said chassis having at least two parallel partitions each formed with a plurality of projections extending outwardly of said partitions, said projections being positioned with spaces between adjacent projections equal to the thickness of a disk drive, said projections being positioned to engage edges of disk drives, said projections being formed with elongated slots for air passage across disk drives supported by said projections, a third partition parallel to and intermediate said first-mentioned at least two parallel partitions formed on two sides with a plurality of projections spaced to engage edges of disk drives, an LED on said motherboard, a horizontal hole through said third partition, and a light transmitting rod in said hole positioned to transmit light from said LED to an end of said third partition remote from said motherboard.
