Assembly lock, threaded bolt with assembly lock, a component with installed threaded bolt as well as a manufacturing process for assembly lock and an assembly method of the threaded bolt with assembly lock

摘要

The present invention relates to a mounting lock 1 adapted to a standardized regular thread RG or a normalized fine thread FG of a threaded shaft 14 of a threaded bolt 10 with a bolt head, so that the mounting lock 1 can be positioned captively on the normalized regular thread RG or the normalized fine thread FG of the threaded shaft 14 and the threaded bolt 10 with assembly lock 1 can be arranged in a component opening 72 so that it cannot be pulled out, the assembly lock 1 has the following features: a cylindrical coil 20 consisting of a plurality of helically wound turns 30, 40, 50 of a wire, in particular a retaining turn 30, a transition turn 40 and adjacent At the second end 24 of the coil 20 is a blocking turn 50, which has a negative slope PB compared to the holding turn 30, so that at least one end region of the blocking turn 50 in the axial direction of the central longitudinal axis L between an insertion position EP and a blocking position BP is elastically displaceable, the end region of the blocking winding 50 in the insertion position EP forming the second end 24 of the helix 20 and being arranged radially outward from the transition winding 40 and / or the holding winding 30 in the blocking position BP.
