FUNCTIONAL ELEMENT, COMPONENT ASSEMBLY COMPRISING THE FUNCTIONAL ELEMENT IN COMBINATION WITH A SHEET METAL PART, METHOD FOR THE MANUFACTURE OF A COMPONENT ASSEMBLY AND ALSO METHOD FOR THE MANUFACTURE OF THE FUNCTIONAL ELEMENT

摘要

The invention relates to a functional element comprising a longitudinal axis, a body part, a hollow pressed part, an annular supporting surface which is arranged on the body part, substantially extended in a perpendicular direction with respect to the longitudinal axis and is radially displaced away from the pressed part and an annular groove which axially extends and is embodied in the body part radially inside the supporting surface. Locking ribs are preferably provided and at least partly cross the annular groove and the free end of the pressed part is provided with an annular cutting edge. The invention functional element is characterized in that an annular bulge is embodied on the pressed part between the annular supporting surface and the free end of the pressed part and an annular cavity is embodied around said pressed part between the bulge and the front free end thereof. An assembly component consisting of the functional element combined with a metal sheet, a method for producing the assembling component and a method for producing the functional element are also disclosed.
