DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention pertains to the general field of structural elements for mounting electronic/electrical assemblies and more particularly to a set of brackets that allow the assemblies to be easily mounted within a computer enclosure.
BACKGROUND ART
From the onset of computer technology, it has been a design goal to create a powerful computer with the least amount of space. In this endeavor, integrated circuitry together with state-of-the-art manufacturing and attachment techniques has considerably reduced the overall packaging space of computers.
To increase the power of a computer in terms of memory capacity and speed, it is necessary to add integrated circuits and/or discrete devices. These devices are usually attached to printed circuit boards. Because of the limited space available in the original design, it is difficult to find space within a computer to add additional boards. Therefore, if an expansion slot is not available or a slot is available but without sufficient room, a separate structure with the required card(s) must be used and connected to the computer by means of an external connector cable.
One of the prime elements that is currently used to increase computer memory capacity is a hard disk drive. These drives are used in combination with a controller card and are typically much larger in terms of bulk than a set of printed circuit boards. Therefore, because of its size, the drive is typically inserted into a dedicated front slot on the computer. The placement of the drive within the computer is difficult in terms of finding space and making electrical connections.
DISCLOSURE OF THE INVENTION
The invention discloses a method that allows a disk-drive/controller card mounting bracket and a slotted hang bracket to substantially increase the power and efficiency of a computer by using the existing but limited space within a computer enclosure.
The disk-drive/controller card mounting bracket is used to create a composite assembly that is comprised of a 3.5-inch Winchester disk drive and its controller interface card. The assembly is then plugged into an existing bus connector that is located within the computer enclosure.
The slotted hang bracket allows a circuit card assembly, disk drive assembly or other electrical equipment, such as a cooling fan, to be mounted within the computer enclosure in a cantilever fashion. The circuit cards can be either mounted on their edge that is, with the edge of the card perpendicular to the bracket's surface or with the plane of the card attached parallel to the bracket's surface. The card configuration selected is dependent on the space available and/or the location of the card.
In view of the above, it is the primary object of the invention to provide a method utilizing the two cards either singularly or together to increase the power and efficiency of a computer, and in particular its memory capacity, by utilizing existing space within a computer.
In addition to the above primary object, it is also an object of the invention to provide a method with associated hardware that:
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the claims taken in conjunction with the accompanying drawings.
