Abstract
A latch for a Compact PCI board, which incorporates inject and eject and engage and disengage functions, has a low profile shape, whereof a fold-down handle operates through a total arc of 90 degrees. Enhanced electromagnetic compatibility (EMC) is provided, by more efficient EMC shielding and by reduced electromagnetic force (EMF) radiation pass-through. The latch, in its inject/eject operation, undergoes a two-phase motion, which utilizes a rotary motion to insert/extract the board from electrical connection, and utilizes a linear motion to engage/disengage the latch pawl from the chassis (keeper). A separate alignment pin block, normally carrying a lead guide pin and a seating guide pin, is independent of the structure for the base of the latch. This permits the alignment pin block to be mounted to the inside of the faceplate and the latch to be mounted to the outside of the faceplate. By so doing, the cumulative (aggregate) area of the opening(s) through the faceplate is reduced, which thereby increases the EMC (electromagnetic compatibility) of the design by reducing EMF radiation pass-through.
