[0012] A further improvement to the above solution is that the thickness of the second copper-plated protective layer is 20-50 μm.

[0013] A further improvement to the above solution is that the corrosion-resistant electroplating protective layer also includes a third nickel-plating protective layer arranged on the outer surface of the second copper-plating protective layer.
