Abstract: Disclosed is a base plate (1) and the protective case of a printed circuit. The plate includes a ventilation filter (4) and at least one rivet blank (5) projecting from the plate and intended to penetrate the printed circuit and to be deformed for rigidly connecting the printed circuit to the base plate by projecting from a face (1a) of the plate, the filter including at least one ventilation opening (6). The rivet blank is borne by the filter and includes an internal tube (7) passing right through the rivet blank in the projecting direction thereof, the internal tube opening, on one side, onto an end of the rivet blank that projects furthest from the plate while forming the ventilation opening and, on the other side, into the ventilation filter.

Abstract: The present invention proposes a protective case for a motor vehicle computer, the case including a ventilation filter (50) and at least one wall (41) including a mounting portion (410) for mounting the ventilation filter, in which portion an opening (42) and at least one air flow channel (43) extending from the opening are formed, the ventilation filter including a membrane (51) covering the opening and a protective member (52) for protecting the membrane, mounted on the mounting portion and defining at least one aperture opening onto the flow channel (43), the flow channel being configured so as to prevent the membrane from being reached by a flow of water traveling along a straight path from the aperture, in order to prevent damage to the membrane by the flow of water.
