Abstract

The invention relates to an enclosure for computers that is formed by slidably joining together two chassis portions. A groove formed in a wall of one chassis portion mates with a tongue formed in a wall of the other chassis portion. The tongue enters one end of the groove and slides throughout the groove's length until the two chassis portions become fully joined and form a completed enclosure. The combination of the tongue and groove forms a slidable tongue and groove joint. When both chassis portions are made of electrically conductive material, the tongue and groove joint effectively inhibits the passage of electromagnetic radiation through the seam that forms at the juncture of the two chassis portions.
