Abstract

In the case of a connector coupling, a rib structure (4) is configured on a hose nipple (3), which rib structure (4) has at least one first rib (5), the at least one first rib (5) extending continuously from a rib start (6) as far as a rib end (7) which is spaced apart axially from said rib start (6), and winding around the hose nipple (3) over a circumferential section of more than 180°, preferably more than 270°, particularly preferably over more than 360° or at least once.

First claim

The invention claimed is:

1. A connector coupling ( 1 ) for a hose, the connector coupling comprising:
a hose nipple ( 3 ), on which a rib structure ( 4 ) with at least one first rib ( 5 ) is configured,
the at least one first rib ( 5 ) being configured to extend around over more than 180° on the hose nipple ( 3 ), and
a rib start ( 6 ) of the at least one first rib ( 5 ) being spaced apart axially from a rib end ( 7 ) of the at least one first rib ( 5 ),
wherein
the at least one first rib ( 5 ) has a profile with an axial deflection ( 14 ) in at least one rib section ( 29 ), wherein the first rib ( 5 ) forms a thread ( 13 ) and the axial deflection ( 14 ) deviates from a course of the thread ( 13 ) locally in the axial direction, thereby forming an additional anti-rotation safeguard.

2. The connector coupling ( 1 ) in accordance with claim 1 , wherein
the rib structure ( 4 ) has three of the first ribs ( 5 ) which are arranged axially next to one another, are configured in parallel with one another, and are separated from one another in each case by second ribs ( 17 ) which extend in a circumferential direction ( 8 ).

3. The connector coupling ( 1 ) as claimed in claim 1 , wherein the at least one first rib ( 5 ) is configured to extend around over more than 270° or to extend around at least once on the hose nipple ( 3 ).

4. The connector coupling ( 1 ) as claimed in claim 1 , wherein the at least one first rib ( 5 ) extends, at least in sections, obliquely with respect to a circumferential direction ( 8 ) and/or obliquely with respect to an axial direction ( 9 ) which runs through the at least one first rib ( 5 ).

5. The connector coupling ( 1 ) as claimed in claim 1 , wherein the at least one first rib ( 5 ) forms at least one thread turn ( 11 ).

6. The connector coupling as claimed in claim 1 , wherein the rib structure ( 4 ) comprises at least two thread turns ( 11 ).

7. The connector coupling ( 1 ) as claimed in claim 1 , wherein the rib structure ( 4 ) comprises at least one further rib ( 20 ) which extends around in an opposite direction with respect to the at least one first rib ( 5 ).

8. A connector coupling ( 1 ) for a hose, the connector coupling comprising:
a hose nipple ( 3 ), on which a rib structure ( 4 ) with at least one first rib ( 5 ) is configured,
the at least one first rib ( 5 ) being configured to extend around over more than 180° on the hose nipple ( 3 ), and
a rib start ( 6 ) of the at least one first rib ( 5 ) being spaced apart axially from a rib end ( 7 ) of the at least one first rib ( 5 ),
wherein
the at least one first rib ( 5 ) has a profile with an axial deflection ( 14 ) in at least one rib section ( 29 ) and wherein
the rib structure ( 4 ) has at least one second rib ( 17 , 20 ) which crosses the at least one first rib ( 5 ) at a crossing point ( 18 ),
the at least one second rib ( 17 ) follows a circumferential direction ( 8 ) as a closed rib or extends as a further rib ( 20 ) around the hose nipple ( 3 ) in an opposite direction to the at least one first rib ( 5 ).

9. The connector coupling ( 1 ) as claimed in claim 2 , wherein the at least one second rib ( 17 ) extends along a circumferential direction ( 8 ) of a main body ( 21 ) or obliquely with respect to the circumferential direction ( 8 ) of the main body ( 21 ).

10. A connector coupling ( 1 ) for a hose, the connector coupling comprising:
a hose nipple ( 3 ), on which a rib structure ( 4 ) with at least one first rib ( 5 ) is configured,
the at least one first rib ( 5 ) being configured to extend around over more than 180° on the hose nipple ( 3 ), and
a rib start ( 6 ) of the at least one first rib ( 5 ) being spaced apart axially from a rib end ( 7 ) of the at least one first rib ( 5 ),
the rib structure ( 4 ) being configured on a main body ( 21 ), wherein
the main body ( 21 ) has a greater outer circumference in a first axial section ( 22 ) of the rib structure ( 4 ) than in a second axial section ( 23 ) of the rib structure ( 4 ), wherein the first axial section is closer to an insertion end of the hose nipple than the second axial section, and
a rib height ( 15 ) of the rib structure ( 4 ) is of smaller configuration in the first axial section ( 22 ) than in the second axial section ( 23 ).

11. The connector coupling ( 1 ) as claimed in claim 10 , wherein the main body ( 21 ) has a smaller outer circumference in a third axial section ( 25 ) of the rib structure ( 4 ) than in the first axial section ( 23 ), the first axial section ( 22 ) being arranged between the second axial section ( 23 ) and the third axial section ( 25 ).

12. The connector coupling ( 1 ) as claimed in claim 10 , wherein the main body ( 21 ) is tapered.

13. The connector coupling ( 1 ) in accordance with claim 10 , wherein
the rib structure ( 4 ) defines an envelope ( 24 ) which has a cylindrical shape, and
a radial spacing between the main body ( 21 ) and the envelope ( 24 ) varies axially such that the rib height ( 15 ) of the at least one first rib ( 5 ) of the rib structure ( 4 ) varies axially.

14. The connector coupling ( 1 ) as claimed in claim 13 , wherein the hose nipple ( 3 ) is comprised of a plastic material.

15. A connector coupling ( 1 ) for a hose, the connector coupling comprising:
a hose nipple ( 3 ), on which a rib structure ( 4 ) with at least one first rib ( 5 ) is configured,
the at least one first rib ( 5 ) being configured to extend around over more than 180° on the hose nipple ( 3 ), and
a rib start ( 6 ) of the at least one first rib ( 5 ) being spaced apart axially from a rib end ( 7 ) of the at least one first rib ( 5 ),
wherein
the at least one first rib ( 5 ) has a profile with an axial deflection ( 14 ) in at least one rib section ( 29 ), wherein the first rib ( 5 ) has a varying rib height ( 15 ) along its profile, such that molded projections ( 16 ) are configured, on which the rib material of the first rib ( 5 ) protrudes from the hose nipple ( 3 ) further than in the vicinity of these molded projections ( 16 ), thereby forming an additional anti-rotation safeguard.

16. The connector coupling ( 1 ) as claimed in claim 15 , wherein the at least one first rib ( 5 ) is configured to extend around over more than 270° or to extend around at least once on the hose nipple ( 3 ).

17. The connector coupling ( 1 ) as claimed in claim 15 , wherein the at least one first rib ( 5 ) extends, at least in sections, obliquely with respect to a circumferential direction ( 8 ) and/or obliquely with respect to an axial direction ( 9 ) which runs through the at least one first rib ( 5 ).

18. The connector coupling ( 1 ) as claimed in claim 15 , wherein the at least one first rib ( 5 ) forms at least one thread turn ( 11 ).

19. The connector coupling as claimed in claim 15 , wherein the rib structure ( 4 ) comprises at least two thread turns ( 11 ).
