<p>The present invention relates to an improved blind rivet assembly for use in forming an electrical contact assembly. In many applications where an electrical contact may be desirable, it is usual for a primary workpiece in the form of a metal plate first to be painted. In such cases, it is necessary in some way to remove the paint, at least in a localised area, from the panel to enable an electrical connection to be made by the rivet assembly. In prior assemblies, an electrical contact member performing this function is formed separately from the rivet assembly, and must be joined thereto. In the present invention, we provide a rivet assembly comprising a rivet sleeve 1 and a pulling mandrel, in which the rivet sleeve comprises a substantially tubular body 2 with a flange 3 at one end, and the pulling mandrel comprises a mandrel head and a pulling stem, characterised in that the tubular body is provided adjacent the flange with at least one tang 14 to remove paint from the region of a hole in a metal workpiece and to dig into the metal to make an electrical connection. <IMAGE></p> |
