Embodiment Construction

[0045] Figure 1 to Figure 1 4 shows an embodiment of a fluid connection device 10 according to the invention, for example for a fluid circuit of a motor vehicle. However, this application is not limiting.

[0046] The device 10 essentially comprises three parts, namely a male connector 12, a female connector 14 and at least one annular seal 16, for example an O-ring.

[0047] The connectors 12 and 14 are intended to fit into each other and to be integral with the pipes or components to be connected.

[0048] These components will be described one by one below, and then the interfitting of these components and the fastening of the connectors 12, 14 will be described.

[0049] ->Male connector 12

[0050]The male connector 12 has a tubular shape with an axis X. As described above, the male connector is intended to at least partially engage the female connector 14 and includes an axial end 12a for attachment to a pipe or component.

[0051] In the example shown, the male co...

Abstract

Disclosed is a fluid connection device (10) comprising a male connector (12) and a female connector (14), which are configured to be fitted one inside the other along an axis X so as to produce a fluid connection, and at least one annular seal (16) carried by one of the connectors and configured to engage with the other connector in order to ensure a seal between the connectors, the connectors being configured to be fastened to each other by resilient snap-fastening and to retain, after fastening, at least one degree of freedom with respect to each other, characterised in that the connectors are fastened together by a double fastening by resilient snap-fastening and by bayonet, this resilient snap-fastening being configured to be irreversible without deterioration so that, after fastening, the device cannot be dismantled without deterioration.

Description

technical field [0001] The present invention relates to a fluid connection device, for example for a motor vehicle, in particular for a fluid circuit installed in the engine compartment, such as an air or water circuit, or a fluid circuit installed under the body of the vehicle, such as fuel circuit or selective catalytic reduction ("SCR", selective catalytic reduction) circuit). Alternatively, the fluid connection device can be used in another field, such as aviation, marine, etc. Background technique [0002] The purpose of a fluid connection device such as a quick connector is to connect two interfaces or connectors together in a sealed, simple, precise and reliable manner. This operation must be performed within seconds, and preferably without special tools. [0003] This type of device comprises two tubular connectors, male and female, respectively, for fitting into each other. The device is completed by an annular seal that ensures the sealing of the connection. ...
