flange (6) extending radially outwardly from an outer
periphery thereof.
An integrally molded layer of elastic insulating material
(8) is disposed around an outer peripheral surface of the rod
(1) and around a portion of an outer peripheral surface of
each of the fittings (2) such that the integral layer of
material (8) contacts the outer peripheral surfaces at
substantially all points thereof and extends up to and between
the flanges (6). The ability of the insulator to resist flash
over between the fittings (2) is improved by making the layer
thicker (i.e., 30% to 40% thicker) in the region of the end
fittings.
Claim 1, which is representative for our purposes,
follows:
10. A composite insulator comprising:
an insulating rod;
end fittings crimped to opposite end portions of
said insulating rod, each of said end fittings
having a flange extending radially outwardly from an
outer periphery thereof; and
