Abstract: A component assembly consists of a first, largely dimensionally stable component having at least two latching protrusions, which are largely diametrically opposed to each other and by which a second, flexible component can be positioned. The second component has cutouts corresponding to the latching protrusions. In an assembled end position, the latching protrusions are positionally fixed in the cutouts. At least one latching protrusion transitions, at the front and at the rear with respect to a positioning direction, into the first component at a largely right angle. Because of the design, very accurate positional fixing between the first component and the second component is possible.

Abstract: A method is provided for connecting a ball to a first component having the following steps: providing a first component which has a through-hole; providing a ball and inserting the ball into the through-hole such that the ball protrudes out of the first component at opposite sides of the first component; placing a first pressing tool on the ball from a first side of the first component and placing a second pressing tool on the ball from a second side of the first component; plastically deforming the ball by pressing together the pressing tools, wherein material of the ball flows both on the first side as well as on the second side of the first component, such that material of the ball covers an edge of the through-hole on the first side and on the second side of the first component, whereby a formfitting connection is produced between the ball and the first component.

Abstract: A method is provided for pressing a ball into a first component, comprising the acts of: providing a first component, which has a circular through hole; providing a ball, in particular a metal ball, the diameter of which is at most as large as the diameter of the through hole, wherein an inner circumference of the through hole extends up to an outer periphery of the ball; inserting the ball into the through hole such that an equatorial plane of the ball lies in a center plane of the first component; pressing the first component in an edge region of the through hole in such a way that material of the first component flows toward the ball and nestles against the outer periphery of the ball in a tightly contacting manner.
