Abstract
A water-tight plastic component, with a ventilation opening for air exchange between the component interior and the component exterior, and with a gas permeable membrane that covers the ventilation opening to prevent the entry of water into the component interior. The membrane is inserted in a cup-shaped recess disposed in front of the mouth of the ventilation opening, and is clamped at the edge, together with a sealing ring, against the bottom of the recess, in order to achieve a simple assembly. The sealing ring and membrane edge are overlapped by segment tabs that are disposed axially spaced from the bottom of the recess and protrude radially from the cylinder wall of the recess, forming an undercut.
Claims12
A water-tight plastic component, which comprises a ventilation opening (11) for air exchange between a component interior (12) and a component exterior (13), a gas permeable membrane (14) that covers the ventilation opening (11) to prevent an entry of water into the component interior (12) through the ventilation opening (11), said permeable membrane is inserted in a cup-shaped recess (15) disposed in front of a mouth of the ventilation opening (11), and is clamped at a membrane edge, together with a sealing ring (17), against a bottom (151) of the recess (15), the sealing ring (17) and the membrane edge are overlapped by segment tabs (18), said segment tabs are disposed at an axial distance from the bottom (151) of the recess (15) and protrude radially from a cylinder wall (152) of the recess (15), thereby forming undercuts (19).
