Embodiment Construction

[0020] exist Figure 1 to Figure 4 The detachable plug connection 1 and its main components are shown in . The plug-in connection 1 has a tubular insert 2 with at least one retaining projection 3 on the outer circumferential side. The insert part 2 can be guided into the sleeve interior of the sleeve-shaped receptacle 4 . The receiving part 4 is connected with a connection element 5 which is required to establish a detachable Connection. After the insert part 2 has been pressed into the receptacle 4, the retaining projections 3 provided on the insert part 2 are engaged from behind by inwardly directed retaining edges 6, 7 which The legs are flexibly or pivotably held on said connecting element 5 .

[0021] The plug connection 1 has a sleeve-shaped locking element 8 which movably surrounds the connecting element 5 so that the locking element 8 can be in the disengaged position and in the figure 1 and figure 2between the locked positions shown in . In the dismounting pos...

Abstract

The invention relates to a releasable plug connection (1) with a tubular plug-in part (2), and with a sleeve-shaped receiving part (4) which has an insertion opening (28) through which the plug-in part (2) is insertable into a sleeve interior of the receiving part (4), wherein at least one annular groove (10) is provided on the inner circumference of the receiving part (4), in which annular groove(10) an annular seal (12) is arranged which provides sealing in the annular gap between the inner circumference of the receiving part (4) and the outer circumference of the plug-in part (2). The plugconnection according to the invention is characterized in that the insertion opening (28) of the receiving part (4) opens out in a first interior portion (29) of the sleeve interior, which first interior portion (29) is configured as a cross-sectional widening in relation to an adjacent second interior portion (31) and is delimited by an annular shoulder (30), and in that an insertion sleeve (32)is insertable in the first interior portion (29) of the sleeve interior, its peripheral edge (33) directed towards the annular shoulder (30) being spaced apart from the annular shoulder (30) in sucha way that the annular groove (10) is formed between the peripheral edge (33) of the insertion sleeve (32) and the annular shoulder (30).

Description

technical field [0001] The invention relates to a detachable plug-in connection with a tubular insert and a sleeve-shaped receptacle, the receptacle having an insertion opening through which the The insert is guided into the sleeve inner cavity of the receiving part, wherein at least one annular groove is provided on the inner circumference of the receiving part, an annular seal is arranged in the annular groove, and the annular seal A seal is made in the annular gap between the inner circumference of the receiver and the outer circumference of the insert. Background technique [0002] A detachable plug connection of the type mentioned at the outset is known from DE 20 2012 000 597 U1. The known plug-in connection designed as a detachable hose connection has a tubular insert with at least one retaining projection on its outer circumference and a sleeve-shaped receptacle, The lumen of the receptacle serves to guide the tubular insert. A connecting element is connected to t...
