The invention discloses a rod secure socket used for charging a high-power autonomous robot. The rod secure socket comprises an insulating support rod, a square copper binding post, a movable spring insulation sleeve, symmetrical ring-shaped copper electrodes, symmetrical electrode insulating covers, symmetrical insulating end covers and a spring, wherein the square copper binding post is arranged in the insulating support rod; the middle section of the insulating support rod is tightly sleeved with the spring insulation sleeve; the insulating support rod is tightly sleeved with the ring-shaped copper electrodes which are arranged outside the spring insulation sleeve; the upper and lower sections of the insulating support rod and the ring-shaped copper electrodes are tightly sleeved with the electrode insulating covers which are arranged outside the spring insulation sleeve; the two ends of the insulating support rod are tightly sleeved with the insulating end covers respectively; the insulating support rod is sleeved with the spring which is arranged in the spring insulation sleeve; the insulating end covers, the electrode insulating covers and the spring insulation sleeve are tightly connected in sequence. The rod secure socket has the beneficial effects that the rod secure socket has a large electrode contact surface; the electrode contract force is determined by the elastic force of the spring; whether electrodes of plugs are clamped in the socket or not, the electrodes are not exposed; the novel socket which is simple and convenient to operate, is good in contact and is secure and reliable is provided for charging the high-power autonomous robot.
