Description
Technical Field
The present invention relates to a device for fastening a component.
Background
Known in general are snap-fit connections (Schnappverbindungen) which, on account of a defined shape of the connection partners (veribindungspartner) and on account of forces (for example pressure or friction forces) between said connection partners, join together at least two connection partners to be connected. The snap connection is embodied as a cantilever beam with a snap hook (schnaphalken). The engaging abutments of the snap-fit connection have structural features such as hooks, knots (Noppen), or protrusions (Wulst). After assembly, this hook engages in a corresponding recess (Vertiefung) or a corresponding recess (Ausschnitt) of the other coupling stop.
Disclosure of Invention
The invention relates to a device for fastening a component, having a cantilever beam which is connected to the component at one end and which has a snap-in hook at the other end, wherein the cantilever beam has a side facing the component and a side facing away from the component, and wherein the snap-in hook is arranged on the side of the cantilever beam facing the component. The cantilever beam has a first attachment region which extends at least partially parallel to the component, and the cantilever beam has an arch on its side facing the component, which arch is arranged between the snap-in hook and the component on the first attachment region of the cantilever beam extending parallel to the component. An undercut (Hinterschneidung) is introduced between the snap hook and the arch. The advantage of such a snap-in connection is simple assembly and disassembly and simple production, wherein the snap-in element is designed, for example, as an integrated component of the components to be connected. It is advantageous that: the clip connection is of the material-compatible (werkstoffgerecht) type of connection and requires little construction space. This type of connection is based on the shape of the connecting straps and depends on the forces, such as pressure or friction, which are applied between the connecting straps. The snap-in connection is furthermore flexible in use, wherein the two engagement elements can be reliably connected to one another by means of a corresponding design.
The arched portion according to the invention on the side of the cantilever beam facing the component reduces the opening between the cantilever beam and the component to be fastened, whereby the length of the snap-in connection can be kept smaller than in the case of a snap-in connection without an arched portion. The undercut between the snap hook and the arch serves as a free surface for the closure, wherein it can be ensured that: the components are securely engaged and secured.
In an exemplary embodiment, the cantilever beam has a second attachment region between the component and the parallel-running first attachment region, which has a first curvature on a side of the cantilever beam facing the component and/or a second curvature on a side of the cantilever beam facing away from the component. By providing the bent portions, stress concentration in these regions can be reduced, whereby deformation of the cantilever beam can be reduced and the connection can be reliably maintained.
Another advantageous embodiment is characterized in that: the surface of the cantilever beam has a first tangential plane and a second tangential plane between the second attachment region and the component, the second attachment region having a first and/or a second bend, the first tangential plane being on the side facing the component and the second tangential plane being on the side facing away from the component; wherein the first tangential plane and the surface of the component are arranged with respect to each other on a side facing away from the cantilever beam with a first angle smaller than 90 ° and/or the second tangential plane and the surface of the component are arranged with respect to each other on a side facing away from the cantilever beam with a second angle larger than 90 °. It is advantageous here that: a positive effect on the stress distribution in the cantilever beam, and a positive effect on the force between the cantilever beam and the component. The stress is thereby better distributed in the cantilever beam, whereby the cantilever beam is reliably maintained on the component.
Another embodiment provides that: the cantilever beam has a third attachment region between the second attachment region and the component, the second attachment region having a first and/or second bend, and the third attachment region having a larger cross-section than the second attachment region, the second attachment region having a first and/or second bend. This positively influences the stress acceptance of the connection between the cantilever beam and the component, wherein the connection between the cantilever beam and the component can accept the stresses in contact and the connection does not come loose here.
In a further development, the snap-in hook at the end of the cantilever beam has a third curvature on the side of the cantilever beam facing the component and/or the snap-in hook has a fourth curvature on the side of the cantilever beam facing away from the component. The advantage here is a simplified joining process, so that the snap hook can be connected better to the counterpart to be connected, or the snap hook can be engaged more simply. Therefore, a lower engagement force is required at a constant holding force.

The cross-section and effective length of the cantilever beam 12 can be variably selected based on the force to be applied. The snap-fit connector 10 is constructed such that: so that the cantilever beam 12 has an elevation (Erh) at the free end or the end not connected to the component 18, namely a snap hook 14, so that the snap connection 10 is inserted by means of the snap hook 14 into a corresponding recess of the other engaging stop or into the counterpart of the connection, wherein the face 20 bears against a corresponding face at the counterpart at the other engaging stop. In this embodiment, the face 20 of the snap hook projects from the cantilever beam at an angle of 90 °. By means of the inclined surface 22 at the snap hook 14, on the side facing away from the component, the snap connection 10 can be connected or engaged with a further engagement partner more easily and with less engagement force.
FIG. 2 illustrates an exemplary embodiment of the snap connector 24 disposed at a surface 60 of the component 26. For example, the clip connection 24 may be secured at the surface 60 of the component 26 by bonding (Kleben), soldering (L-fosten), or welding (schweii beta ben), or the clip connection 24 and the component 26 may be integrally implemented.
The snap-in connection can be used, for example, to fasten a component to a support or to a housing in a display system in a motor vehicle. Therefore, the decorative element (zierelementete) can be preferably arranged in particular at the display system. For this purpose, the component with the snap-fit connection and the further engaging stop are joined together and held by the snap-fit connection. The further engagement strap can be embodied, for example, as a plate (plate), a strip (leister), a support or a housing.
The snap-in connection 24 has a cantilever beam 28 with a side 30 facing the component and a side 32 facing away from the component, and a snap-in hook 34 at the end of the cantilever beam 28, wherein the snap-in hook 34 on the side 30 facing the component of the cantilever beam 28 is arranged at the opposite, free end of the cantilever beam 28 which is not connected to the component 26. The cantilevered beam 28 is configured with a bend whereby a first appendage region of the cantilevered beam 28 extends at least partially parallel to the component 26. In fig. 2, this is illustrated by a plane of symmetry 36 through the first appendage region of the cantilever beam 28, which extends parallel to the component 26.
The cantilever beam 28 has a curved portion 38 on the side 30 facing the component, which is arranged between the snap-in hook 34 and the component 26 on a first auxiliary region of the cantilever beam 28 extending parallel to the component 26. The bends are preferably embodied as semi-circular projections (Erhebung) protruding from the surface of the cantilever beam 28. An undercut 40 is introduced between the snap hook 34 and the bend 38, wherein the snap connection 24 engages with the undercut 40 at the other engaging stop or at the other counterpart. The undercut 40 is, for example, a recess (aussapraung) provided with a radius in the cantilever beam 28.
In this embodiment, between the component 26 and the first appendage region extending in parallel, the cantilever beam 28 has a first bend 42 on the side 30 of the cantilever beam 28 facing the component; and the cantilever beam has a second bend 44 on the side 32 of the cantilever beam 28 facing away from the component; they constitute a second subsidiary zone.
The surface of the cantilevered beam 28 has a first tangential plane 46 between the first bend 42 and the component 26 on the side 30 of the cantilevered beam 28 facing the component. On the side facing away from the cantilever beam, this first tangential surface 46 is arranged with a first angle 50 of less than 90 ° towards a surface 60 of the component 26. The surface of the cantilever beam 28 has a second tangential surface 48 between the second bend 44 and the component 26 on the side 32 of the cantilever beam 28 facing away from the component. On the side facing away from the cantilever beam, this second tangential surface 48 and a surface 60 of the component 26 are arranged with respect to each other with a second angle 52 greater than 90 °.
The cantilevered beam 28 has a third attachment region 54 between the second attachment region and the component 26, the second attachment region having the first bend 42 and/or the second bend 44. This third appendage region 54 has a larger cross section than the second appendage region, which has the first and/or second bend 42, 44.
The snap-in catch 34, which is arranged at the free end of the cantilever beam 28 that is not connected to the component 26, is a projection from the cantilever beam 28, wherein a surface 55 projects behind the undercut 40, which surface rests against a corresponding surface of a further engaging stop after the engaging process with the further engaging stop (for example a plate, strip, support or housing). The snap-in connection 24 is thereby engaged by the snap-in hooks 34 in corresponding recesses of the other mating snap-in part or in the mating counterpart of the connection. Furthermore, the snap-in hook 34 has a third bend 56 on the side 30 of the cantilever beam 28 facing the component and a fourth bend 58 on the side 32 of the cantilever beam 28 facing away from the component.
