Fastening device for a fastening system for fastening components

By using the elastic clip design, the stud receiving part opens elastically when inserted and is fixed by the locking element, which solves the problems of high installation force and insufficient holding force in the existing fastening system, and achieves high holding force and size compensation under low installation force.

AI Technical Summary

Technical Problem

Existing fastening systems require significant force during installation, but lack sufficient holding force after installation and are difficult to compensate for dimensional deviations.

Method used

The design employs an elastic clip, where the stud receiving part elastically opens upon insertion to allow insertion of the stud head. A locking element prevents the opening, ensuring that the stud can only be removed laterally once it is secured.

Benefits of technology

It achieves high holding force with low installation force, can release the fastener again without damage, and can compensate for dimensional deviations.

Abstract

本发明涉及一种用于将部件紧固至部件载体的紧固系统的紧固装置，其中螺柱从部件载体的表面突出。紧固装置包括弹性夹，其包括具有螺柱接收部的基体，螺柱、尤其是螺柱的螺柱头部可至少部分地或局部地被接收在螺柱接收部中，且随后可通过自锁固定在螺柱接收部中。螺柱接收部被配置为使得当螺柱插入螺柱接收部中时，其弹性地张开以至少部分地或局部地接收螺柱、尤其是螺柱的螺柱头部，其中，弹性夹的基体包括至少一个锁定元件，其被配置为当与螺柱的插入方向相反的力被施加在至少部分地或局部地被接收在螺柱接收部中的螺柱上时，阻挡螺柱接收部的尤其弹性的张开。
