- the slots in the outer sheath region 9 are open on the side facing the sleeve part 4 and terminate in the head region 8.
- the slots 19, 20 are the perspective views of the holding part in Fig. 1, 2, 6 and 7, and particularly good Fig. 6, refer to. They ensure with advantage the deformability, in particular of the support arms 7 and the snap arms 10, but also the following
- the slots 19, 20 cause in terms of a high functionality of the receiving part 2 advantageous circumferential segmentation of the holding part 6 of the receiving part 2 according to the invention in six outer Segments 10, 21 in the outer sheath region 9 and in six inner segments 7, 22 in the inner sheath region 13.
- Two circumferentially opposed slots 9 in the outer sheath region 9 are preferably each in a plane of a radial longitudinal section through the holding part 6, in each case two circumferentially lie opposite slots 20 in the inner shell region 13.
- Each segment 10, 21 in the outer jacket region 9 is thus associated with a segment 22, 7 in the inner jacket region 13, ie it lies opposite it - seen in the radial direction.
- Inner jacket region 13 are formed by the retaining arms 7 for the plug part 3. That at a regular angular offset of 60 ° in each case a slot 19 passes through the outer shell and a slot 20 through the inner shell, allows - as already mentioned - the Haiiearme 7 and the Schnapparme 10 are arranged alternately with a mutual angular displacement of 60 °.
- segments 21 are located in the outer sheath region 9 opposite the holding arm segments 7 in the inner sheath region 13, and what type the segments 22 are in the inner sheath region 13 facing the Schnapparm segments 10 in the outer sheath region 9 .
- These segments 21, 22 are outer holding and guiding segments 21 and inner holding and guiding segments 22 for the sleeve part 4.
- an inner holding and guiding segment 22 forms in each case in the inner jacket region 13 with its opposite Schnapparm segment 10 in the outer jacket region 9 - connected by the head portion 8 - in longitudinal section C-shaped bracket for the sleeve part 4, in which this can be axially guided and held.
- the sleeve part 4 is also between each an outer support and guide segment 21 and a support arm 7 for led the plug part 3.
- a play or transition fit can preferably be provided between the adjoining parts.
- the inner holding and guiding segments 22 in the inner jacket region 13 serve together with the alternately arranged between them holding arm segments 7 at the same time for the axial guidance of the male part 3 during its assembly and disassembly.
- outer holding and guiding segments 21 are shorter in the illustrated embodiment than the Schnapparm segments 10.
- FIGS. 3 and 4 the one show further advantageous feature of the invention. It can be seen from the drawing that the outer holding and guiding segments 21, which are formed as walls of a hollow cylinder in the basic form, in the assembled state abut against the jacket 4c of the sleeve part 4, which is likewise hollow-cylindrical in its basic form. On the jacket 4c is a circumferentially extending, diverging in the insertion direction S inclined surface 4d.
- This inclined surface 4d causes when attaching the holding member 6 on the sleeve part 4, first a radial deflection of the outer holding and guiding segment 21, which - as the Schnapparme 10 - is also resiliently spreadable. As soon as the holding part 6 is released after being plugged on, this spring elasticity effects a radial return of the outer holding and guiding segment 21 and, by cooperation with the inclined surface 4d, an automatic axial return movement of the holding part 6 against the plugging direction S into a position in which which lie in the lying between the guide segments 21 outer snap arms 10 with their latching hooks 10 a at the latching step 12. An axial Kochsteck the locking element 6 is thus prevented or automatically compensated immediately.
- the sleeve part 4 is also segmented on its side facing the holding part 6.
- This segmentation comprises at least one retaining claw 23, preferably - as shown - three retaining claws 23 with three circumferential recesses lying in between. The latter are for the sake of clarity only in Fig. 9 and 0 marked with the reference numeral 24.
- the latching of the sleeve part 4 with the holding part 6 takes place in the peripheral region of the recesses 24.
- the retaining claws 23 lugs 23a With radially inwardly directed tip, which are similar to the locking hooks 10a of the snap arms 10.
- the lugs 23a come to the radially outward side the support arms 7 to the system and block their possible outward movement, which is necessary to mount the plug part 3 or disassemble again.
- the holding arms 7 can exert a radially acting force in the locking position on the lugs 23a.
- a blocking effect against displacement of the holding part 6 in the insertion direction S is achieved by friction.
- the holding arms 7 can be displaced in the axial plug-in direction S, that is, the holding part 6 and the sleeve part 4 can be compressed axially more strongly than in the locked position be given in various places between some components in the axial direction XX possible game.
- This necessary axial clearance is - indicated by the reference numeral A - entered in Fig. 3.
- the axial clearance A should also be present between the end face 4a of the sleeve part 4 in the region of its respective frontal recess 24 and the underside of the head region 8 facing the sleeve part 4 in the region of the snap arms 10.
- the axial clearance A can advantageously be chosen very small according to the invention.
- the axial clearance in the receiving opening 5 of the sleeve part 4 between the tip 3b of the plug part 3 and the bottom 25 of the sleeve part 4 is also minimal in that the shape of the bottom 25 in the receiving opening 5 of the sleeve part 4 is adapted to the shape of the tip 3b of the plug part 3. This creates an optimally small freezing volume in this area.
- the receiving part 2 passes from the locking position shown in Fig. 4 by the insertion of the plug part 3 in the release position.
- the plug part 3 is moved in the insertion direction S against the receiving part 2 until its holding stage 3a, located on its outer circumference ring approach, at a first, converging in the insertion direction S inclined surface 7a of the support arms 7 of the holding member 6 comes to rest.
- This should lead to a radial spreading of the support arms 7, but just by the radial outer stop of the retaining arms 7 on the lugs 23 a of the retaining jaws 23rd is prevented.
- this Upon further insertion of the plug part 3, this therefore takes the holding part 6 in the insertion direction S and pushes this deeper into the socket part 4. Due to the presence of the described axial clearance A, this is possible.
- Inclined surface 4d of the sleeve part 4 has characterized - as in the pre-assembly of the holding part 6 and sleeve part 4 - experienced a radial deflection.
- the latching hooks 10a of the snap arms 10 have been removed by plugging back from the latching step 12 on the outer circumference 1 1 of the sleeve part 4 in the insertion direction S axially.
- After releasing the plug part now comes the above-described interaction of the outer holding and guiding segment 21 with the diverging in the insertion direction S inclined surface 4d of the sleeve part 4 to the effect.
- the resilience of the outer holding and guiding segment 21 causes in
- the holding part 6 may have a third, again in the insertion direction S converging inclined surface 7 d on the support arms 7 of the holding part 6.
- the holding part 6 may have a third, again in the insertion direction S converging inclined surface 7 d on the support arms 7 of the holding part 6.
- the holding part 6 can be provided with the same function on the lying between the retaining arms 7 inner support and guide segments 22 a stop surface 22c, namely with the function that there in a Kochsteck plug part 3 - from the mounting position (Fig. 4) out further in the insertion direction S - in each case the holding stage 3a of the plug part 3 comes to rest.
- Further pressing of the plug part 3 in the insertion direction S causes a relative movement of the holding part 6 and sleeve part 4 against each other until the desired release position of the support arms 7.
- Such disassembly possibility is compared to the known prior art, a simplification and therefore provides increased ease of use of the fluid of the invention - Plug-in coupling 1.
- the receiving part 2 of the invention does not necessarily have three by 120 ° staggered holding arms 7 and three offset by 20 ° staggered Schnapparme 10 on the holding part 6 according to the invention, but possibly could also be a number of two be sufficient, or it could be four or more holding arms 7 and snap arms 10 are provided. Accordingly, then the segmentation of the outer and inner holding and guiding segments 21, 22 would be designed.
- a joint 27 may be provided, as shown in FIG. 1 1 shows.

- the sleeve part 4 of the second (and third) embodiment differs from that of the first embodiment in that in an axial region - in the insertion direction S behind the latching step 12 and the indicator window 36 lying -
- On its outer circumference 1 1 at least one radially outwardly projecting web extension 37, in the illustrated embodiment preferably three circumferentially by 120 ° staggered radially outwardly projecting web extensions 37 are located.
- These web extensions 37 which could also be referred to as flange sections, are likewise intended for cooperation with the secondary locking part 50.
- the sleeve part 4 of the second (and third) embodiment differs from that of the first embodiment in that also located in an axial region in the insertion direction S behind the latching step 12 - diametrically opposite in Fig. 7 the indicator window 36 - on its outer circumference 11th at least one radially projecting locking lug 38 for the secondary locking member 50 is located.
- the secondary locking member 50 which is to be regarded as specific to the second (and also the third) embodiment of the invention, shown as a single part.
- the secondary locking part 50 serves to prevent accidental release of a fluid plug-in coupling 1 according to the invention. It is a capping part for the composite of sleeve part 4 and holding part 6, ie in the assembled state, these two parts 4, 6 on the outside, in particular directly the outer jacket region 9 of the holding part 6, as can be seen in the further figures 21 to 35.
- the secondary locking part 50 is annular and can - like the sleeve part 4 and the holding part 6 - are manufactured in a simple manner as one-piece plastic injection molded part. It has six axially directed radially resiliently expandable snap arms 51, 52 in the illustrated embodiment.
- the locking member 50 has at least one radially inwardly facing nose 53, in the illustrated embodiment, three lugs 53, for cooperation with the
- the Schnapparme 51, 52 are through slots 54, which from one through the
- Slots 54 extend circumferentially interrupted bottom portion 55 of the locking member 50 and ends in a circumferentially closed head portion 56, separated from each other.
- the number of snap arms 51, 52 can be made variable. In minimal version of the locking part 50, two snap arms 51, 52 are provided.
- the longer snap arms 52 can be easily recognized in the drawing figures by having an ergonomically designed fluted handle portion 57 to better engage the latch member 50 to be able to turn its longitudinal axis XX.
- All Schnapparme 51, 52 have in the bottom portion 55 for latching behind the holding member 6 radially inwardly directed lugs 51 a, 52 a.

- the nose 61d thereby engages in the recess 58 in the nose 51a of a shorter snap-51, as illustrated by Fig. 24 (top).
- the locking part 50 can not be rotated about the longitudinal axis X-X. The same applies at the beginning of the insertion of the plug part 3, if there is a state, as is present in FIG. 25.
- Recess 58 in the nose 51 a of the shorter Schnapparmes 51 must be disengaged. This requires a frictionally locking connection between the nose 51a of the snap-51 and the Arretieransatz 38 ahead. This can - as illustrated by the drawing - be achieved in that the Arretieransatz 38 has a rounded contour and the recess 58th in the nose 51 a of the shorter Schnapparmes 51 has inner lateral inclined surfaces. These are for the sake of clarity only in Fig. 30 denoted by the reference numeral 58 a. Likewise, so that the locking connection can be made in the first ever before, ie so that the nose 51 a through the
- Arresting approach can be run over to provide also outer lateral inclined surfaces 58b, which are also designated only in Fig. 30.
- the secondary locking member 50 can be pressed in the insertion direction S, wherein the pressure on the lugs 53 (additionally circled in Fig. 33) is transmitted from the secondary locking member 50 evenly on the holding part 6.
- the plug part 3, not shown in FIG. 33 - as well as the other FIGS. 29 and 32 - can then be removed from the receiving part 2, so that the connection of the fluid plug-in coupling 1 according to the invention is canceled again.
