Self-piercing press-in element, press-in connection and method for producing such a press-in connection

摘要

The self-piercing press-in element, in particular punched nut (2), has a head part (6) with a head rest (8) for placement on a component (22) and a stamped collar (10) with an end cutting edge (24). Between the punched collar (10) and the head rest (8) an undercut (26) is formed. A peripheral displacer web (16) is then formed on the head support (8) on the stamped collar (10), to which a further outer region (18) of the head support (8) adjoins in the radial direction (14) ) is set back relative to the displacer web (16). In the formation of the press-in connection, material is pressed from the upper side (28) of the component (22) into the undercut (26) by means of the displacer web (16). A deformation of the underside (34) of the component (22) is preferably not.
