Abstract: The present invention is directed to a device retention apparatus. A method of retaining an electronic device in a housing may include engaging a first device side of an information handling system device against a first housing side of a housing suitable for retaining an information handling system device. The housing includes the first housing side, a second housing side, and a third housing side, wherein the second housing side is oriented generally opposing the first housing side, and the third housing side oriented is generally perpendicular to the first housing side and the second housing side. The information handling system device includes a first device side, a second device side, and a third device side. The information handling system device is rotated about the engaged portion of the information handling system device with the housing, so that the information handling system device is secured to the first housing side, second housing side and third housing side.

Abstract: A computer system chassis, including a base and a cover, implements an improved grounding system by integrally forming a plurality of flexible protruding contacts into predetermined contact regions throughout the base during the metal punching manufacturing phase of the chassis base blank. In this way, when the base and cover are attached to each other, the size of any gaps which may form in these contact regions, as a result of warpage or design tolerances, are reduced. This is due to the number of mechanical contacts being made by the plurality of flexible contacts which protrude and extend across these gaps and connect the base to the cover. In addition to reducing the size of these gaps, the flexible contacts provide an improved electrical grounding to the cover by increasing metal-to-metal contact between the cover and the base, both of which reduce EMI emissions from the computer system chassis.

Abstract: A shielding panel for shielding circuit card slots on a computer chassis, and particularly a shielding panel for use with printed circuit board brackets and/or blank brackets to shield circuit card slots provides an arrangement for reducing the leakage of electromagnetic waves and/or radio frequency waves through a computer chassis by providing protrusions around circuit card slots in the slot frame. The design of the present shielding panel includes a tab which wraps around an edge of the circuit card slot to help place and hold the shielding panel in position while substantially eliminating the potential interference between neighboring panels and/or panels and neighboring slots and inhibits the formation of a gap between the shielding panel and the computer chassis slot frame, therefore, substantially eliminating the chance of a bracket tip catching in such a gap.
