Abstract
A degassing unit for an electronics housing has a base body with gas passage opening and is connectable fluid-tightly to a rim of a pressure compensation opening of the electronics housing. A semipermeable membrane for covering the pressure compensation opening enables passage of gaseous media from an environment into the electronics housing interior and vice versa but prevents passage of liquids and solids. A membrane support device, arranged at an interior side of the base body facing the electronics housing interior, engages across the gas passage opening and is positioned at a first distance to the semipermeable membrane. A separation lattice with lattice openings is arranged at the interior side of the base body at a second larger distance to the semipermeable membrane and completely engages across the gas passage opening. A surface area spanned by the separation lattice is larger than a cross section of the gas passage opening.
