Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Some embodiments of the connection arrangement according to the present disclosure are described in greater detail in the following with reference to the drawings, which show, in each case schematically:

[0024] FIG. 1 a section of the connection arrangement;

[0025] FIG. 2 a three-dimensional drawing of the connector with the support body placed upon.

DETAILED DESCRIPTION

[0026] FIG. 1 shows a connection arrangement 1 for an air conditioning system, in this embodiment a mobile air conditioning system for a motor vehicle. The connection arrangement 1 comprises a connector 2, which is connected to a first pipe 12 in a firmly bonded manner on one side. The connector 2 can be connected to a further pipe 5 or another component of the air conditioning system. The connector 2 comprises a cylindrical portion 4, which can be inserted into pipe 5 or into the other component of the air conditioning system. Further, the connector 2 comprises a radial flange 6, a support body 8 being assigned to the radial flange 6. The support body 8 encloses the passage channel 3 and is providedlike the radial flange 6with a radially protruding projection 9. The projection 9 is equipped to be able to receive a fastening

[0027] means 10. For this purpose, a drill hole, into which a screw which forms the fastening means 10 can be inserted, is formed in the support body 8.

[0028] The connector is made from plastic material, in this embodiment from polyamide 6 (PA 6). The first pipe 12 is also made from polyamide 6 and fixed into the connector 2 in a firmly bonded manner via rotation welding. Alternatively, it is conceivable to make the connector 2 from a resin-based plastic material. The support body 8 consists of metallic material. In this embodiment, the support body 8 consists of steel. The connector 2 is produced by injection moulding and the support body 8 by die cutting.

[0029] A sealing element 7 is assigned to the radial flange 6. The sealing element 7 is arranged in the gap between the radial flange 6 and the end face of the further pipe 5 or the component, and seals in an axial direction. The sealing element 6 is formed as an elastomer and metal composite seal (slim line seal washer) and consists of an annular elastomer portion which is fixed to a metallic support ring.

[0030] Alternatively or in addition, it is conceivable to form the sealing element 7 as O-rings and to insert them into grooves built into the radial flange 6 or into the outer circumference of the cylindrical portion 4 of the connector 2.

[0031] The further pipe 5, which is connected to the connector, is in the form of a plastic material pipe and in the present embodiment consists of polyamide 6 (PA 6). The further pipe 5 is equipped at an end face with a connection flange 11. The connection flange 11 also comprises a drill hole for receiving the fastening means 10.

[0032] The radial flange 6 and the support body 8 are formed congruently on the mutually facing faces, the projection 9 of the support body 8 being bent at its free end in such a way that it encloses the radial flange 6 in portions in the bent region. In an alternative embodiment, a projection, which comes into contact with the support body 8, is formed from the end face of the further pipe 5 or the further component.

[0033] To produce the connection arrangement, the connector 2 is inserted into the further pipe 5 after the sealing element 7 has been arranged in the gap between the radial flange 6 and the further pipe 5. The support body 8 is applied to the radial flange 6, and a fastening means 10 produces a rigid connection between the connector 2 and the pipe 5. The projection of the support body 8 comes into contact in such a way that the support body 8 is supported. If the fastening means 10, for example a screw, is tightened, the support body 8 is pressed steadily against the radial flange 6, and the radial flange 6 is in turn pressed against the sealing element 7 steadily over the circumference with parallel displacement. As a result, the sealing element 7 is pressed steadily resulting in a durable and high sealing effect.

[0034] In an advantageous embodiment the connection arrangement 1 according to FIG. 1 and FIG. 2 is part of a mobile air conditioning system. The connection arrangement 1 connects components of the mobile air conditioning system such as pipes, especially pipes of plastic material with further components such as a condenser or evaporator.
