Abstract
A computer chassis with a mother board and at least one slot opening in the back of the chassis and a daughter board attached to the chassis by a bulkhead. The bulkhead is slid into the slot opening in a self-aligning manner until the daughter board is mated to an electrical connector on the mother board. The bulkhead fits snugly into the slot opening due to side and bottom flaps on the bulkhead and wedge shaped springs on the sides of the slot opening. The top of the computer housing contains a feature to capture and hold a top edge of the daughter board against movement. The top of the computer housing also contains an EMI liner and spring clips that correspond to the top edge of the bulkhead and secures the bulkhead in the computer housing, thus providing consistent and improved EMI/RFI containment.
