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…
