Abstract:

A disk array subsystem for use in a data processing system. In one embodiment, the disk array subsystem comprises a generally rectangular chassis having a top wall, a bottom wall, a pair of side walls, an open front end and an open rear end. Disposed within the chassis are three power supplies, a pair of controller boards, a backplane, and a set of twenty disk drive modules. A mounting structure comprising four first disk drive module guide plates and a pair of second disk drive module guides is fixedly mounted within the chassis for removably mounting the disk drive modules in the chassis through the open front end and for placing the disk drive modules in approximate alignment with the backplane for electrical connection therewith. Each first guide plate is shaped to include five parallel slotted channels, and each second disk drive module guide plate is shaped to include ten parallel grooves. Each of the twenty disk drive modules includes an elongated frame having a longitudinally extending T-bar adapted for slidable insertion into one of the slotted channels and a longitudinally extending fin adapted for slidable insertion into one of the grooves.

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 regulator card is mounted on the frame for movement in three directions using bifurcated squeezable snaps inserted through oversized holes formed in the regulator card. Each snap includes a tab which limits upward movement of the card.

Abstract:

A portable computer is sized to fit into a businessman's attache case and may be seated on a surface for use in either a normal position or a tilted forward position. The portable computer includes a housing having a base, a front top cover, a rear top cover and a foot door. The front top cover is pivotally attached to the front of the rear top cover and the rear top cover is fixedly attached to the base. Computer electronics (i. e. printed circuit boards), and two floppy disk drives are mounted inside the housing on the base at the rear and a full size keyboard is mounted inside the housing on the base at the front. A battery pack is disposed in the rear top cover of the housing. A full size liquid crystal display monitor is mounted on the front top cover. The foot door is movably mounted on the back of the base. When the front top cover is pivoted open the display screen is viewable and the keyboard is accessible.

Abstract:

A disk array subsystem for use in a data processing system. In one embodiment, the disk array subsystem comprises a generally rectangular chassis having a top wall, a bottom wall, a pair of side walls, an open front end and an open rear end. A fan pack is removably mounted over the open rear of the chassis to cool the contents thereof by drawing air into the chassis through the open front end and out of the chassis through the open rear end. Disposed within the chassis are three power supplies, a pair of controller boards, a backplane, and a set of twenty disk drive modules. A mounting structure comprising four first disk drive module guide plates and a pair of second disk drive module guides is fixedly mounted within the chassis for removably mounting the disk drive modules in the chassis through the open front end and for placing the disk drive modules in approximate alignment with the backplane for electrical connection therewith. Each first guide plate is shaped to include five parallel slotted channels, and each second disk drive module guide plate is shaped to include ten parallel grooves. Each of the twenty disk drive modules includes an elongated frame having a longitudinally extending T-bar adapted for slidable insertion into one of the slotted channels and a longitudinally extending fin adapted for slidable insertion into one of the grooves.

US Classification:

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.

H05K 7/14

Abstract:

A package for securing a PCB to a heatsink includes mounts with over-torque protection features. The PCB is seated in an open end of the package. Each mount includes a threaded opening for securing the package to the heatsink such that the base layer of the PCB is thermally coupled to the heat sink. The over-torque protection features are connected between the threaded opening and a sidewall of the package. The over-torque protection features may be designed to structurally fail and/or deform in response to over-torqueing of the fasteners, thereby inhibiting flexure of the PCB.
