Computer chassis having a size-adjustable, TEM-shielded circuit board support plate structure therein
First Claim
1. Computer apparatus comprising:
- a computer chassis having a wall with an inner side; and
an adjustable, transverse electromagnetic mode-shielding circuit board mounting plate structure including;
a first base wall secured to said inner side of said computer chassis wall in a parallel relationship therewith and being supportingly attachable to a first underside portion of a printed circuit board, said first base wall having a transverse first peripheral edge lip laterally projecting away from said computer chassis wall and having an end portion longitudinally projecting parallel to said computer chassis wall and outwardly beyond the balance of said first base wall, anda second base wall secured to said inner side of said computer chassis wall in a parallel relationship therewith for movement relative thereto in a direction parallel to the length of said first peripheral edge lip between first and second positions, said second base wall having a transverse second peripheral edge lip laterally projecting away from said computer chassis wall and having an end portion longitudinally extending transversely to said end portion of said first peripheral edge lip and outwardly beyond the balance of said second base wall, said end portions of said first and second peripheral edge lips being transversely and releasably interconnectable with one another with said second base wall in each of said first and second positions thereof.

Abstract
A computer chassis has a cotton side wall upon which a two-section support plate structure is mounted. Each of the two support plate sections has, along a side edge periphery thereof, an upturned TEM shielding lip portion. The plate sections are supportingly securable to the underside of a printed circuit board, such as the computer motherboard, and are slidably adjustable relative to the underlying bottom chassis side wall to selectively adjust the overall size of the support plate structure so that different sizes of printed circuit boards may be alternatively secured thereto while maintaining proper spacing between the TEM shielding lip portions and adjacent side edge portions of the supported circuit board.

12. Computer apparatus comprising:
-
a computer chassis having a bottom wall with an inner side; and an adjustable, transverse electromagnetic mode-shielding circuit board mounting plate structure including; a first section having a first base wall attachable to a first underside portion of a printed circuit board, and a first peripheral edge lip laterally extending transversely to said first base wall and having an end portion longitudinally extending outwardly from the balance of said first base wall in a direction generally parallel thereto, a second section having a second base wall attachable to a second underside portion of the printed circuit board, and a second peripheral edge lip laterally extending transversely to said second base wall and having an end portion longitudinally extending outwardly from the balance of said second base wall in a direction generally parallel thereto, first mounting means for mounting said first base wall on said inner side of said bottom chassis wall, in a parallel relationship therewith, for sliding movement relative thereto in opposite directions transverse to the length of said first peripheral edge lip, and for releasably locking said first base wall to said bottom chassis wall in a selectively variable adjusted position thereon, second mounting means for mounting said second base wall on said inner side of said bottom chassis wall, in a parallel relationship therewith and with said second peripheral edge lip extending transversely across said first peripheral edge lip, for sliding movement relative to said bottom chassis wall in opposite directions transverse to the length of said first peripheral edge lip, and for releasably locking said first base wall to said bottom chassis wall in a selectively variable adjusted position thereon, and cooperating interlocking means on said first and second peripheral edge lips for releasably holding them together in a transversely crossed relationship. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
