Patent JP-H03261012-A (JP)
Title: Electrolytic corrosion resistance insulator
Inventor: NAKAMURA ITSUSHI
IPC: H01B17/50
Filed: 1990-03-08
Abstract: PURPOSE:To prevent electrolytic corrosion of a second plated layer and corrosion of a pin metal fitting by providing a first plated layer of a metal having larger standard electrode potential than a current flowing anode on the surface of a pin metal fitting, and providing the second plated layer of a metal having smaller standard electrode potential than the standard electrode potential of the metal of this plated layer on its surface. CONSTITUTION:When cement 9 is wetted in an ordinary charged state and only the surface is dried, a flow-out leakage current I1 from a second plated layer 11 of a pin fitting 7 flows out to the cement 9 side. When a deficit part K is partially produced due to corrosion, rain water containing alkaline penetrating inside cement 9 breaks into this deficit part K. This rain water further corrodes zinc of the second plated layer 11 to expose a first plated layer 10. An anti-corrosion current (i) flows from the layer 11 to the layer 10 due to an electrode potential difference between the zinc layer 11 and the copper layer 10 through rain water (electrolyte) of the deficit part K. Since the electrode potential can be increased by about four times, the anti-corrosion current (i) can be increased. Therefore, the flow-out leakage current I1 is suppressed to suppress promotion of corrosion of the second plate layer 11 due to zinc.
