Abstract

A fluid connection system for a cleaning system of a car includes at least two connections, wherein each of the at least two connections includes a male connector and a female connector. For each of the at least two connections the male connector includes an outlet opening and the female connector includes an inlet opening, and the male connector and the female connector are configured to fluidly connect the outlet opening to the inlet opening in an assembled state. For each of the at least two connections the length of the male connector is adapted to the length of the female connector. The length differs for each of the at least two connections.

Claims (71)

1 . A fluid connection system for a cleaning system of a car,

wherein the fluid connection system comprises at least two connections,

wherein each of the at least two connections comprises a male connector having a first length and a female connector having a second length,

wherein for each of the at least two connections the male connector comprises an outlet opening and the female connector comprises an inlet opening,

wherein for each of the at least two connections the male connector and the female connector are configured to fluidly connect the outlet opening to the inlet opening in an assembled state,

wherein for each of the at least two connections the first length of the male connector is adapted to the second length of the female connector,

wherein

the first length and the second length differ for each of the at least two connections,

wherein

the male connector comprises at least one limiting element,

wherein the at least one limiting element is spaced apart from the outlet opening,

wherein the female connector comprises at least one restriction mean,

wherein the at least one restriction mean is spaced apart from the inlet opening,

wherein the first length is a distance from the at least one limiting element to the outlet opening and the second length is a distance from the at least one restriction mean to the inlet opening,

wherein

the at least one limiting element exhibits an outer diameter,

wherein the outer diameter of the at least one limiting element is different for each male connector of the at least two connections,

wherein the female connector of at least one of the at least two connections comprises

an insertion space,

wherein the insertion space is arranged between the at least one restriction mean and

an open end of the female connector of the at least one of the at least two connections,

wherein the insertion space exhibits an inner diameter,

wherein the inner diameter of the insertion space of the female connector of at least one of the at least two connections is the same as the outer diameter only of the at least one limiting element of the male connector of the same connection of the at least two connections.

2 . The fluid connection system according to claim 1 ,

wherein

the male connector of one connection of the at least two connections only matches to the female connector of the same connection of the at least two connections.

3 . The fluid connection system according to claim 1 ,

wherein

the at least one restriction mean abuts against the at least one limiting element in the assembled state, and/or

wherein the outlet opening is adjacent to the inlet opening in the assembled state.

4 . The fluid connection system according to claim 1 ,

wherein

an inner diameter of the outlet opening and an inner diameter of the inlet opening are the same for all of the at least two connections.

5 . The fluid connection system according to claim 1 ,

wherein

the male connector is detachably connected with the female connector, and/or wherein the male connector is connected with the female connector in a form-locking and/or force-locking manner.

6 . The fluid connection system according to claim 1

wherein

the female connector comprises an opening at least partially extending from the inlet opening to the at least one restriction mean.

7 . The fluid connection system according to claim 6 ,

wherein a retaining element is arranged inside the opening.

8 . The fluid connection system according to claim 7 ,

wherein the retaining element fixes the male connector to the female connector in the assembled state.

9 . The fluid connection system according to claim 7 ,

wherein the retaining element fixes the male connector to the female connector in the assembled state, in a form-locking and/or force-locking manner.

10 . The fluid connection system according to claim 1 ,

wherein

the female connector comprises a sealing element,

wherein the sealing element is arranged at the inlet opening.

11 . The fluid connection system according to claim 10 ,

wherein the sealing element is a D-ring.

12 . The fluid connection system according to claim 1 ,

wherein

the fluid connection system comprises a valve,

wherein the valve is fluidly connected with the at least two connections.

13 . The fluid connection system according to claim 1 ,

wherein

the fluid connection system is designed for a fluid pressure from 5 bar up to 12 bar.

14 . The fluid connection system according to claim 1 ,

wherein

the male connector and the female connector of each of the at least two connections have a corresponding rotation symmetry.

15 . The fluid connection system according to claim 14 ,

wherein

the rotation symmetry is realized by a rotationally symmetric cross section.

16 . The fluid connection system according to claim 15 ,

wherein the rotationally symmetric cross section is realized by a notch and/or a polygonal cross section.

17 . The fluid connection system according to claim 1 ,

wherein

the fluid connection system consists of three connections.

18 . A car, comprising a tube, a nozzle and the fluid connection system according to claim 1 ,

wherein the tube, the nozzle and the fluid connection system are fluidly connected.
