Embodiment Construction

[0049] at the beginning Figure 1 to Figure 9 In , the same components are always assigned the same reference numerals and are therefore usually only described once.

[0050] The plug-in connection 1 according to the invention comprises two connecting parts, namely a housing part 2 and a plug part 4 . The plug part 4 can be inserted via the socket 6 into the receiving opening 8 of the housing part 2 and is closed by at least one peripheral sealing ring 10 and locked against release by means of a locking device 12 .

[0051] The locking device 12 is constructed in such a way that on the one hand it ensures a partially inserted pre-stop position (see figure 2 and 7 ) and on the other hand ensure fully inserted full stop position (see Figure 4 , 8and 9). In the pre-locking position, which is positively locked against loosening, the plunger 6 is not completely sealed in the receiving opening 8 in such a way that a signal is generated under the pressure of the pressure mediu...

Abstract

The present invention relates to a plug-in coupling for pressure-medium lines, comprising a housing part and a plug part, wherein the plug part can be inserted into a receiving opening in the housing part by way of a plug shaft in a sealed manner and can be locked against coming loose by means of a locking device. The locking device is designed in such a way that a partially inserted preliminary latching position and a fully inserted full latching position are ensured, wherein the plug shaft is incompletely sealed in the receiving opening so as to allow leakage of the pressure medium in the preliminary latching position, whereas sealing is complete in the full latching position. The locking device firstly comprises a radial latching recess, which is bounded by a retaining flank, of one coupling part and secondly comprises a double-latching element of the other coupling part, wherein the double-latching element has two radially spring-elastic latching elements which are arranged axially one behind the other in such a way that the first latching element engages behind the retaining flank of the latching recess in the preliminary latching position and the second latching element engages behind said retaining flank of the latching recess in the full latching position. Radially protruding support means are arranged within the latching recess in a region which is situated axially between the two latching elements in the full latching position.

Description

[0001] This application is an application for an invention patent with the application date of June 3, 2009, the application number 200980127628.5 (the international application number is PCT / EP2009 / 056794), and the invention name is "Plug-type connection device for pressure medium conduit". Divisional application. technical field [0002] The invention relates firstly to a plug-in connection for a pressure medium conduit, which comprises two connecting parts, namely a housing part and a plug part, wherein the plug part can be is inserted into the receiving opening of the housing part in a peripheral sealing manner and can be locked against release by means of a latch; wherein the latch is configured to ensure a partially inserted pre-stop position and a fully inserted The full stop position; wherein, in the pre-stop position, the shank is not completely sealed in the receiving port, so that the pressure medium leaks, and in the full stop position, it is completely sealed; whe...
