Abstract: THIS INVENTION RELATES TO PERSONAL COMPUTERS, AND MORE PARTICULARLY TO THE PROVISION OF SHIELDING FOR ATTENUATING THE EMISSION OF ELECTROMAGNETIC RADIATION AND THE LIKE FROM AN ENCLOSURE FOR SUCH COMPUTERS, A PERSONAL COMPUTER (10) IN ACCORDANCE WITH THIS INVENTION HAS A CHASSIS (19) FOR MOUNTING A PLANAR BOARD (20) AND HAVING A BASE (22), A FRONT PANEL (24), AND A REAR PANEL (25). THE FRONT PANEL DEFINES AT LEAST ONE BAY (26) FOR RECEIVING A DATA STORAGE DEVICE. IN ORDER TO ATTENUATE THE EMISSION OF ELECTROMAGNETIC RADIATION THROUGH THE WINDOWS FORMED FOR THE BAYS IN THE FRONT PANEL OF THE CHASSIS, THIS INVENTION CONTEMPLATES THAT AT LEAST ONE MANUALLY REMOVABLE SHIELD MEMBER (90) WILL BE MOUNTED IN ANY BAY.(FIG. 4)

Abstract: THIS INVENTION RELATES TO ENCLOSURES FOR MICROCOMPUTERS, AND MORE PARTICULARLY TO SUCH AN ENCLOSURE WHICH FACILITATES ACCESS TO AND SHIELDING OF THE OPERATIVE COMPONENTS OF A PERSONAL COMPUTER (10). THE ENCLOSURE INCLUDES A CHASSIS (19), A COVER (15) FOR COOPERATING WITH THE CHASSIS FOR ENCLOSING A VOLUME TO CONTAIN OPERATING COMPONENTS OF THE MICROCOMPUTER, AND INTERRUPTED WEDGE MEMBERS FOR COUPLING THE CHASSIS AND COVER UPON RELATIVE MOVEMENT THEREBETWEEN IN A PREDETERMINED DIRECTION. THE INTERRUPTED WEDGE MEMBERS INCLUDE A PLURALITY OF HOOKS (101) ON ONE OF THE CHASSIS AND COVER AND A PLURALITY OF POCKETS (102) ON THE OTHER, WITH THE HOOKS AND POCKETS BEING DISPOSED ALONG TWO SIDES OF THE CHASSIS AND COVER FOR ENTRY OF HOOKS INTO COOPERATING POCKETS ON MOVEMENT OF THE COVER INTO POSITION FOR COOPERATION WITH THE CHASSIS IN ENCLOSING VOLUME.(FIG. 4)

Abstract: This invention relates to personal computers, and more particularly to the provision of shielding structure for attenuating the possible effects of electromagnetic interference on input/output circuits of the computer while structurally reinforcing a side edge portion of a multilayer planar board. The shielding structure has two cooperating constituent parts, one being particularly formed ground plane areas in exterior layers of the planar board and the other being a particularly formed thin sheet metal member which extends about and substantially encloses connectors by which input/output signals are passed to circuits within the planar board.
