摘要

The invention relates to an aircraft computer comprising a box (1) with a casing (50) into which the removable modules (10, 20) are inserted, each of the modules consisting of: a printed circuit board (60) carrying electronic components; a stiffening frame (61) made of metal positioned against the printed circuit board on the same face thereof as carries the electronic components, said stiffening frame comprising a longitudinal member (62) which extends along a first side of the printed circuit board, two external arms (63) which extend from the longitudinal member along two adjacent sides of the printed circuit board and at least one central arm (64) which extends from the longitudinal member parallel to the external arms; and a sheet metal cover (65) having a flat which covers a free face of the stiffening frame, said cover being extended by a return (68) disposed at a right angle, which covers the longitudinal member (62) of the stiffening frame (61) and ends in a lip (70) that comes into contact with the cover of an adjacent module or the casing of the box.
