Definitions
- Pipe connector for a fluid-carrying line with a hollow cylindrical receiving part, which has an inner, axially extending receiving area, into which a hollow cylindrical connector is inserted in the axial direction, radial projections being arranged on the inside in the receiving part to prevent rotation, characterized in that on the Radial projections are arranged on the outside of the connector and cooperate with the radial projections of the receiving part to prevent rotation.
- a plug connection of this type has become known in the prior art from DE-U-299 22 692.
- a water pipe can be connected to a fitting.
- the connector is a plastic fitting with two ends, with the water pipe being pressed onto one end so that a press connection is created.
- the water pipe is a multi-layer pipe made of an inner aluminum layer and outer plastic layers.
- the other end of the plastic fitting is inserted in the receiving part and anchored by means of a snap ring.
- the receiving part is an adapter made of brass.
- the plastic fitting has a circumferential bead at its front, inserted end, which is in clamping connection with knobs of the receiving part.
- the invention has for its object to provide a pipe connector of the type mentioned, which avoids the disadvantages mentioned and which can still be produced inexpensively.
- both the receiving part and the connector thus have projections which engage in one another and thus result in an inhibition of rotation.
- Such interlocking of projections can absorb dimensional deviations much better than the known clamp connection.
- the different projections are preferably arranged on the inside of the receiving part. If projections of different heights are provided on the inside of the receiving part, the preferred wise made of plastic connector deformed by these higher projections. This deformation increases the engagement of less high protrusions between the higher protrusions.
- the insertion forces are essentially caused by the higher projections.
- at least three higher projections are provided on the receiving part in a symmetrical arrangement and lower projections between them.
- FIG. 1 shows a section through a pipe connection according to the invention
- FIG. 2 shows a section through a receiving part
- FIG. 3 shows a section along the line III-III of FIG. 1
- FIG. 4 schematically shows the deformation of the connector
- FIGS. 5 and 6 schematically the interlocking of projections with different tolerances.
- the pipe connection 1 shown in FIG. 1 has a receiving part 2 which has a receiving area 4 which, as can be seen, is continuous and into which a connector 3 is inserted.
- a snap ring In a widened area 4a, a snap ring, not shown here, is inserted, which engages over a flange 5 and anchors the connector 3 in the receiving part 2.
- a utility model DE-U-299 22 692 For this purpose, reference is made to the utility model DE-U-299 22 692.
- the receiving part 2 is an adapter and has a thread 6 on the outside, onto which, for example, a fitting (not shown here) is screwed.
- the receiving part 2 is in particular made of metal, preferably brass.
- the connector 3 has two identical ends 3a and 3b.
- the end 3a engages in the receiving area 4 according to FIG. 1.
- a tube 14 is placed on the other end 3b and pressed in a manner known per se. Sealing rings 11 each ensure liquid-tight connections between the end 3a and the receiving part 2 and the pipe 14 and the end 3b.
- the tube 14 is in particular a water tube and has an inner layer 14a made of aluminum and layers 14b and 14c made of plastic.
- the connector 3 is preferably made of plastic.
- the receiving part 2 has a plurality of ribs 12 on the inside, which form radial projections and which, as can be seen, extend in the axial direction. On the inside, these ribs 12 merge with inclined surfaces 12c into the inner surface 15 of the receiving area 4.
- the length of the ribs 12 is considerably shorter than the length of the receiving part 2 and is preferably less than 10 mm.
- the connector 3 also has ribs 13 on the outside, which extend in the axial direction and which engage between the ribs 12 of the receiving part 2.
- the ribs 13 are thus also projections and form a toothing with the ribs 12, which has an anti-rotation effect.
- 3 several such ribs 13 are evenly distributed around the circumference of the end 3a.
- the number of ribs 12 is equal to the number of ribs 13. While the ribs 13 are preferably all of the same height, the ribs 12 of the receiving part 2 are of different heights. In Fig. 3, the high ribs are designated 12a and the lower ribs 12b.
- three high ribs 12a are provided in a symmetrical arrangement and nine lower ribs 12b. Between each two adjacent ribs 12a are arranged three lower ribs 12b.
- the height of a rib 12a is, for example, 1 mm and the height of a rib 12b is 0.5 mm.
- connection between the receiving part 2 and the plug 3 is made by plugging these two parts together in the axial direction. Shortly before they are completely plugged together, the projections 12 and 13 engage in one another in the manner of a toothing.
- the connector 3 is slightly deformed by the higher ribs 12a, as indicated in FIG. 4. In FIG. 4, only the higher ribs 12a and corresponding depressions 13b of the connector 3 are shown to illustrate the deformation. This deformation requires a certain insertion force when joining the connection. This insertion force is now dependent on the dimensional tolerances of the receiving part 2 and the connector 3.
- the receiving part 2 can also be slightly deformed radially by a screwed-on part.
- FIG. 5 shows a connection which was joined with a comparatively small insertion force and in which, for example, the connector 3 has a comparatively small outside diameter.
- the higher ribs 12a deform the connector 3, while the lower ribs 12b engage without contact between the ribs 13.
- the anti-rotation is nevertheless ensured by the ribs 12a as well as by the ribs 12b.
- the deformation of the connector 3 by the higher ribs 12a is greater than in the arrangement according to FIG. 5.
- the lower ribs 12b engage in the recesses 13b of the connector 3 without any space. In this case, the torsion resistance is significantly higher. 5 but also sufficient.
- the ribs 12a are of different heights.
- An embodiment is also conceivable in which the ribs 13 are of different heights.
- the number of ribs 12 and 13 can be different. However, at least three higher ribs 12a are preferably provided.
- a plurality of lower ribs 12b are preferably arranged between two adjacent higher ribs 12a.
