Abstract
This invention is related to a microcomputer associated to a printed circuit connector adapted to connect main circuits to extension circuits. Said connector comprises pressure means associated to a lid covering an aperture provided in the casing of the microcomputer, which pressure means act on a cartridge containing extension circuits. When said lid is in its closed position, the conductive connecting areas, or contacts, of the printed support circuit associated to said extension circuits are maintained in engagement with conductive elastic blades constituting the connecting contact of the main circuits. The invention is particularly advantageous in the field of microcomputors manufactured and distributed on a large scale.
