Abstract of the Disclosure
Connecting means are disclosed for establishing an
electrical connection between sheet metal elements that are to
be connected together by screw means. The elements are per-
forated for the passage of the screw means and the perforations
are formed in pressed-out conical areas in the sheet metal ele-
ments. The conical elements are adapted to mate when secured
together, with the outer surface of one conical area mating with
the inner surface of the other conical area. One of the outer
and inner surfaces is formed with narrow integral radial ribs
for engaging the other of the outer and inner surfaces to make
electrical connection when the screw is tightened.
