Rf grounding and heat distribution system for a portable computer

Abstract

A grounding system for a portable computer system which provides the computer system with a desirable RF (radio frequency) grounding and heat distribution characteristics. The grounding system includes a top panel, a back panel, and a bottom panel, where the panels are constructed of electrically conductive material. The bottom panel is electrically and physically connected to the back panel. The top panel and back panel are connected physically and electrically via low impedance hinges. A computer display such as a liquid crystal display (LCD) is electrically and physically coupled to the top panel, and a system planar printed wiring board is electrically and mechanically coupled to the bottom panel. The grounding system includes side panels constructed of electrically conducted material that are electrically and physically connected to both the top panel and the bottom panel. The top panel and the back panel are also connected via a spring hinge. Mounting bosses are attached to the top panel and the display. Mounted bosses are also attached to the bottom panel and the display. Heat is transferred from the bottom panel to the top panel via the back panel and the hinges. The low impedance hinge is a slip joint hinge with a banana plug type male intrusion member.
