Then, apply a top pressure to the electrical connection head relative to the electrical connection socket. Through the mutual coordination and cooperation of the electrical connection head and the electrical connection socket, force the positioning guide sliding spacer plate on the spring-return telescopic mechanism to slide backward, compress the compression spring cooperating with it and place it in place. Then, rotate the electrical connection head around the center of the electrical connection head and place it in place, so that the reverse cone end on the electrical connection head rotates along the positioning guide flange on the electrical connection socket and aligns and enters the end of the positioning guide flange. After reaching the position, release the top pressure, and rely on the resilience of the spring-return telescopic mechanism to force the electrical connection head to retreat and place it in place, so that the reverse cone electrical contact surface A on the reverse cone end of the electrical connection head and the reverse cone electrical contact surface B on the end of the positioning guide flange of the electrical connection socket are overlapped and wedged with each other to complete the connection and conduction. When removing, just push the electrical connection head forward to the in-place position and reverse-rotate it back to the starting end hole of the positioning guide flange to pull it out. The methods are: alignment and insertion → top pressure in place → rotation in place → release of top pressure —— retraction and overlap —— wedging conduction, top pressure in place —— separation and disconnection → reverse rotation and return → spring-back and pull out.

After reaching the position, reverse-rotate the A part of the inverted cone and inverted wing backward overlapping electrical connection device, so that the inverted cone end on it rotates along the positioning and guiding flange on the B part of the inverted cone and inverted wing backward overlapping electrical connection device to the starting hole of the positioning and guiding flange to pull it out).

When removing, just press the A part of the inverted cone inverted cone wing backward overlapping type electrical connection device forward to the position and reverse-rotate it to the original position to pull it out (after applying the top pressure, since the positioning and guiding ring sleeve column on the A part of the inverted cone inverted cone wing backward overlapping type electrical connection device moves forward, forcing the positioning and guiding sliding spacer plate that cooperates with it to slide backward and compress the compression spring on the spring-back type telescopic mechanism. After reaching the position, reverse-rotate the A part of the inverted cone inverted cone wing backward overlapping type electrical connection device, so that the inverted cone end on it rotates along the positioning and guiding flange on the B part of the inverted cone inverted cone wing backward overlapping type electrical connection device to the starting hole of the positioning and guiding flange to pull it out).
