Abstract
A degassing unit for an electronics housing has a base body to be connected fluid-tightly to a rim of a pressure compensation opening of the electronics housing. The base body has a gas passage opening covered by a semipermeable membrane that enables passage of gaseous media but prevents passage of liquid and solids. A fluid-permeable protective screen with screen openings is arranged at an inner side of the base body across the gas passage opening. The base body has a thread engagement region for screw-connecting the degassing unit to the electronics housing. The protective screen has a screw through opening aligned with the thread engagement region of the base body. At the screw through opening, a thread engagement region of the protective screen is provided that fixes the protective screen by a threaded fastening element immediately relative to the electronics housing in a mounted state of the degassing unit.
