Abstract: A housing for receiving an electronic circuit (4) having a plurality of components (5) having a carrier plate (7) and a housing cover (8) including a circumferentially enclosing wall (9) on the carrier plate (7) and a cover part (10) on the wall (9), which cover part (10) lies opposite the carrier plate (7). A volume compensation element (11) is attached on the carrier plate (7) in an interior (12) of the housing cover (8) which is enclosed in a pressure-tight manner from an external atmosphere. The volume compensation element (11) is elastically formed providing a variable volume for compensation of pressure fluctuations in the interior (12), which variable volume occurs with a change in position of the volume compensation element (11) relative to the carrier plate (7). A gap between the volume compensation element (11) and the carrier plate (7) is connected to the external atmosphere.

Abstract: A protective screen assembly (1) for a fan includes a cover part (2) having an air passage opening (4) and a protective screen (6). In the area of the passage opening (4), the protective screen (6) is connected to the cover part (2) via detent connections (8) distributed over the circumference so as to close the passage opening as protection against contact. Each detent connection (8) includes a detent shoulder (10) in the passage opening (4) and a detent element (12) on the protective screen (6). In the area of each detent element (12) at the outer edge of the protective screen (6), the protective screen (6) is resiliently deformable such that each detent element (12), for engaging and disengaging the detent connection (8), can be moved radially relative to the related detent shoulder (10), regionally deforming the protective screen (6).
