Abstract

A fastening element including a shaft; a shaft head arranged at an end of the shaft, wherein the shaft head has a larger diameter than the shaft, wherein the fastening element is provided for arranging a first component and a second component at each other, wherein the first component is provided as a circuit board provided with a LED and the second component is provided as a heat dissipating lamp element, wherein the shaft is insertable through a pass through opening of the first component and the shaft head is configured at least for an indirect contact at the first component, wherein the shaft is arrangeable in a recess of the second component, wherein the shaft is fixable at least through friction locking in the recess of the second component.

First claim

What is claimed is:

1. A fastening element, comprising:
a shaft;
a shaft head arranged at an end of the shaft,
wherein the shaft head has a larger diameter than the shaft,
wherein the fastening element is provided for arranging a first component and a second component at each other,
wherein the first component is provided as a circuit board provided with a LED and the second component is provided as a heat dissipating lamp element,
wherein the shaft is insertable through a pass through opening of the first component and the shaft head is configured at least for an indirect contact at the first component,
wherein the shaft is arrangeable in a recess of the second component,
wherein the shaft is fixable at least through friction locking in the recess of the second component,
wherein the fastening element is provided with an insulating element which is arranged between the shaft head and the first component and prevents a contact of the shaft head and the first component,
wherein the insulating element is made from a spring elastic material and clamps the first component against the second component through the shaft head,
wherein the shaft includes diameter expending support elements configured as interlocking hooks which are configured to enter a form locking engagement with the second component,
wherein a free end of at least one shaft lobe is crimped and forms a support element which is supported at another shaft lobe,
wherein the support element supports the at least one shaft lobe and the other shaft lobe in a rigid manner in a normal position in which the interlocking hooks protrude beyond an inner radius in a circumference expanding manner,
wherein the insulating element terminates flush on the first component, and
wherein the interlocking hooks engage a side of the second component that is oriented away from the fist component.

2. The fastening element according to claim 1 , wherein the insulating element is made from an electrically non-conductive material.

3. The fastening element according to claim 1 , wherein the fastening element is made from metal.

4. The fastening element according to claim 1 , wherein the insulating element includes a pass through opening through which the shaft of the fastening element is run.

5. The fastening element according to claim 1 , wherein the shaft is formed by two parallel shaft lobes.

6. The fastening element according to claim 1 , wherein both shaft lobes respectively include a support element and the support elements are supported at each other.

7. An arrangement, comprising:
the fastening element according to claim 1 ;
the first component; and
the second component,
wherein the shaft head contacts the insulating element,
wherein the insulating element contacts the first component,
wherein the first component contacts the second component,
wherein the insulating element is supported at the shaft head and induces a contact force between the first component and the second component.

8. The arrangement according to claim 7 , wherein the insulating element is clamped against the first component by the fastening element and a reset force thus induced generates a contact force between the first component and the second component.

9. A method for arranging two components at each other by the fastening element according to claim 1 ,
wherein the first component includes a pass through opening and the second component includes a recess, the method comprising the steps:
arranging the first component and the second component at each other, wherein the pass through opening and the recess are aligned with each other;
inserting the fastening element assembled from the retaining clamp and the insulating element with a free shaft end forward in an insertion direction through the pass through opening into the recess until the insulating element contacts the first component;
sliding the interlocking hooks at edges of the pass through opening and of the recess and spring elastic displacing of the interlocking hooks into an interior space of the fastening element;
continuing an insertion movement in the insertion direction with an insertion pressure that compresses the insulating element in a spring elastic manner;
building up reset forces by the insulating element which reset forces act against the insertion pressure; and
penetrating the recess with the interlocking hooks and interlocking the interlocking hooks at a bottom side of the second component.
