FASTENING DEVICE, A COMPONENT COMPRISING THE FASTENING DEVICE, AND METHOD FOR PRE-ASSEMBLING THE FASTENING DEVICE

摘要

The invention relates to a fastening device 1 for fastening a component 2 to a counter piece. The fixing device 1 comprises a thread 6, a screw head 7 and a collar screw 3 having an annular collar 8 formed therebetween. The fixing device 1 further comprises a fixing section 4 of a component 2 in which a through hole 5 comprising a radial stop protrusion 9 located therein is formed. The collar screw 3 is inserted in the through hole 5 in the insertion direction 12, and in the pre-assembly state, the collar 8 of the collar screw 9 is in the pull-out direction 13 and the through hole 5 ) Is supported on the stop protrusion 9 in the axial direction. According to the invention, a radial clamping protrusion 10 is formed in the through hole 5 which is located inward and radially opposite the stop protrusion 9 and is axially offset to the stop protrusion 9 in the insertion direction 12 do. In the pre-assembly state, the collar 5 is axially supported on the clamping protrusion 10 in the insertion direction 12, so that the collar screw 3 is clamped between the stop protrusion 9 and the clamping protrusion 10. do. The invention also relates to a component 2 comprising a fixing device 1 and a method for pre-assembly of the fixing device 1.
