Abstract
A press-in connection for a pre-perforated component includes a press-in element having a head part with a head seat and a compression collar which adjoins the head part in a press-in direction. The compression collar has a base portion and a filling portion. The filling portion adjoins the base portion so as to form an internal step oriented toward a center axis. In a production process, an annular free space between an embossing collar of a die and a perforated wall is thus reliably filled with collar material through bulk deformation of the collar material, thereby ensuring good pull-out resistance as well as good resistance to torsional movement and watertightness.
Claims20
A press-in element or press-in nut extending in a press-in direction along a center axis for forming a press-in connection with a pre-perforated component, the press-in element comprising:
- a head part with a head seat for resting on the pre-perforated component;
- and
- a compression collar adjoining said head part in the press-in direction;
- said compression collar having a thread-free configuration and a front end in the press-in direction, a base portion and a filling portion, said filling portion adjoining said base portion to form an internal step oriented toward the center axis;
- said base portion having an axial base height extending from said head seat to said step, and said filling portion having an axial filling height extending from said step to said front end of said compression collar.
