Abstract:
A blind rivet connector for being passed through a bore in a workpiece and clinched to prevent withdrawal, said connector comprising:an enlarged reaction head portion for being retained by the workpiece surface to one side of the bore;a tubular portion capable of passing through said bore and including:remote from said head portion an end portion incorporating an internal releasable engagement configuration, anda plastically deformable region intermediate said end portion and said head portion,and a relatively non-deformable collar adjacent said head region, said collar of diameter less than said bore and axial dimension at least equal to that of said bore,whereby, in use, the application of compression to clinch said connector causes said plastically deformable region to deform plastically, and said non-deformable collar allows plastic deformation sufficient to prevent later removal of said connector but not to prevent limited radial float of said connector relative to said hole.
