The needle shaft and the needle tube are riveted together. The spring is accommodated in the needle tube and squeezed between the needle shaft and the needle tube, so that the needle shaft can expand and contract axially. The needle tube is usually a one-piece structure, made of stainless steel or brass with gold plating. Stainless steel has high contact resistance, and copper gold plating is not corrosion-resistant. The needle tube is often corroded by sweat or other substances, which leads to poor electrolysis of the spring probe during charging.
