DGG
1. The conductive plate has no stop lock, the maximum rotation opening is not less than 160 degrees, and there is no stainless steel yellow clip at the home of the conductive plate. It is passivized, riveted, and installed with high elasticity to maintain the contact pressing force.
2. The main electric circuit parts are made of T2 red copper, and the static contact and terminal block are drawn by integral profiles, which completely solve the problem of poor contact caused by the welding of static contact and terminal block in the past.
3. All the conductive parts of the main circuit are silver plated with a thickness of no less than 20mm. with the closed anti-oxidation treatment technology, the surface coating is bright and durable, with strong anti-oxidation capacity, excellent conductivity, and circuit resistance of £ 80mm.
4. The terminal block is of double hole structure, made of hard copper alloy, and the outer layer is silver plated.
5. The external pressure contact spring is adopted, and the conductive contact surface contacts the "fixed arc" structure, with high uniform pressure and self-purification. The contact pressure remains unchanged for a long time to ensure the safety and reliability of the product for long-term travel
