Patent ID: 10598203

Abstract:
A functional element having a section that has a flange, that projects away from a side of the flange, and is adapted for an aperture-free punching into a sheet metal part and having a shaft part that projects away from a side of the flange opposite the first side, that satisfies a function and that is provided with a longitudinal axis. The flange and the section are arranged at least substantially coaxially to the shaft part. The section is formed as a hollow cylinder that has notches extending in parallel with the longitudinal direction at at least one of its outer jacket surface and its inner jacket surface. The section has a diverging frustoconical shape that runs out at least substantially at the free end at the inner side of the section in the region of its free end and that serves for the widening of the section on the punching in the sheet metal part. A component assembly and a method of producing the latter is also claimed.
