Abstract

A method is provided for producing a component connection. The method includes the steps of: providing a first component that is made of a thermoplastic plastic material at least in the region of a portion of the surface thereof; providing a ball that is made of a thermoplastic plastic material in at least one region of the surface thereof; pressing the ball on the first component such that the thermoplastic plastic material of the ball comes into contact with the thermoplastic plastic material of the first component; vibrating the ball using an ultrasonic sonotrode and welding the ball with the first component; providing a second component having a through hole; bringing the second component to the first component in such a way that the ball projects at least into the through hole of the second component or a portion projects to a certain extent through the through hole; clipping a clip element to the ball, wherein the clip element projects beyond the through hole and joins both components to one another in an interlocking and/or force-locked manner.

First claim

What is claimed is:

1. A method for producing a component connection, the method comprising the acts of:
providing a first component which is made of a thermoplastic plastic material at least in the region of a part of its surface;
providing a ball which is made of a thermoplastic plastic material at least in a region of its surface;
pressing the ball onto the first component such that the thermoplastic plastic material of the ball bears against the thermoplastic plastic material of the first component;
vibrating the ball via an ultrasonic sonotrode and welding the ball to the first component;
providing a second component which has a through-hole;
bringing the second component up to the first component such that the ball projects at least into the through-hole of the second component or projects to a certain extent through the through-hole; and
clipping a clip element onto the ball, wherein the clip element projects beyond the through-hole and interconnects the two components in an interlocking and/or force-locking manner.

2. The method according to claim 1 , wherein
the first component has a physical marker, and
the ball is positioned relative to the first component via the physical marker.

3. The method according to claim 2 , wherein the physical marker of the first component is a trough-shaped depression.

4. The method according to claim 1 , further comprising the act of:
introducing an adhesive layer between the first and second components.

5. The method according to claim 4 , wherein the introducing of the adhesive layer is carried out by applying the adhesive layer to a side of the first component that faces the second component.

6. The method according to claim 4 , wherein the introducing of the adhesive layer is carried out by applying the adhesive layer to a side of the second component that faces the first component.

7. The method according to claim 1 , wherein the act of vibrating the ball via the ultrasound sonotrode is carried out via translational vibrations.

8. The method according to claim 1 , wherein the act of vibrating the ball via the ultrasound sonotrode is carried out via torsional vibrations.

9. A component connection produced by the method according to claim 1 .

10. A component connection produced according to the method of claim 2 .

11. A component connection produced according to the method of claim 4 .
