functional for mounting on a sheet metal element, assembled component it made therefrom and method of assembling the functional element to a sheet metal part

摘要

1. A functional element (10) for mounting a sheet metal part, such as, for example, a nut member (10) or a bolt element with a body portion (12) or a head portion merges to a tramocilíndrico (20), wherein the functional element has no an annular flange, but the transition from the head portion (12) or decuerpo part to the section (20) is formed by an at least substantially conical surface ( 16) hacetransición directly to the head portion (12) or the body portion and forming a surface Paraúna seat conical area corresponding (42) of a sheet metal part (40) having an opening, several lugs security against rotation are provided in the conical surface of the functional element, extending ina axial plane along the length of the conical surface and are distributed uniformly around the ejelongitudinal the functional element providing security against rotation lugs are ext ienden axially along at least a portion of the length axialdel cylindrical section (20), the free end of the cylindrical section (20) direction is preferably configured as a punching section ydespués mounting the functional element to a sheet metal part can be moved in axial direction the materialde lugs security against rotation which extend along the cylindrical portion (20) to form in Placesof location of the tenons providing security against rotation projections of material extending radially haciafuera and coming to It is located in the edge region of the opening of the piece of sheet provided.
