Abstract
The present invention relates to a pressure medium plug-in connector, consisting of two connector parts, i.e. a housing part (2) and a plug part (4), wherein the plug part (4) with a plug shaft (6), via at least one peripheral seal (10) located in an annular groove (14) of the one connector part (4) and interacting with a peripheral sealing surface (18) of the other connector part (2), can be inserted in a sealed manner into a receiving opening (8) of the housing part (2) and can be secured against release by means of a locking arrangement (12). The locking arrangement (12) is constructed in such a way that a partially plugged, prelocked position and a completely plugged, fully locked position are ensured. In the prelocked position, a seal is present which is so incomplete that, if pressure is applied with a pressure medium, a clearly limited perceptible leak, particularly in the form of an audible leaking sound, occurs. In the fully locked position, via the peripheral seal (10) resting against the sealing surface (18), a complete, pressure-tight seal is present. The area of the peripheral seal (10) and/or of the sealing surface (18) is constructed in such a way that the peripheral seal (10), located in the annular groove (14) of the one connector part (4)--in the prelocked position [and] via peripherally distributed contact points (20) arranged a distance apart--rests in radial direction against the other connector part (2), wherein respectively in peripheral direction, between the contact points (20), axial leakage paths (22) are formed. Hereby, the peripheral seal (10) is protected against a tearing out brought about by the flow.
