With the reference of SEA/USCAR-20(standard of auto connector's test) and auto connector's development,we analyzed the possible problems of auto connector's reliability and analyzed the reasons that affect connector's reliability: the contact resistance and contact force affect auto connector's reliability directly.The paper also pointed out some reasons that cause the instability of contact resistance and contact force,such as stress relaxation,permanent deformation,corrosion,pollution on the surface,vibration and fretting.It proposed to improve the auto connector's reliability by plating.
