Definitions
- the invention is based on a fastening element for components in an opening or a method according to the preamble of claim 1 or claims 10 or 11.
- the flow straightener has arrow-shaped latching hooks which protrude somewhat radially outwards from its outer surface and which can snap into a circumferential groove provided in the inner wall of the opening.
- the Spring elements When inserting the flow straightener into the opening, the Spring elements are elastically deformed and exert a spring force on the flow straightener.
- the latching hooks snap into the groove and hold the flow straightener permanently in the opening with the help of the spring force of the spring elements.
- This has the disadvantages that the spring elements must be manufactured and attached individually, and a second element, namely that of the latching hook, is necessary in order to permanently fix the components.
- the fastening element according to the invention and the method with the characterizing features of claim 1 or claims 10 or 11 therefore have the advantage that at least one component can be fastened in an opening in a particularly simple manner. Another advantage is that the use of a single element for fastening, ie for axial securing, which at the same time brings about axial compensation, for the at least one component which is completely accommodated in an opening of an air mass measuring device and the number of components Elements reduced from two to one. This reduces the manufacturing costs. Furthermore, the check for the presence and functionality of another element is omitted.
- the compact design of the fastener enables easy assembly and therefore high

- the fastening element 1 in the direction of the normal 2nd is wavy.
- the height difference between wave crest 3 and wave trough 8 is, for example, 5 mm.
- Fig. 3c four wave crests 3 can be seen, which are offset by 90 °.
- the execution of such a fastener is not limited to this number and even distribution of wave crest and valley.
- the fastener 1 is advantageously made of plastic or metal.
- Fig. 4 shows schematically such as with a
- Tool 25 exerts a force F in the direction of arrows 22 on the spring washer and this is radially deformed in the direction of arrows 26 when a corresponding base such as the components resting on the stop 15 is present.
- the tool 25 is here, for example, a tube.
- the outer diameter of the tube 25 is at most as large as that of the fastening ring 37, the thickness of the tube not being wider than the width of the
- Fastener 1 needs to be, but can also be thicker.
