The slow pop-up design can reduce the risk of accidental contact or short circuit, and the slow pop-up can reduce the impact force on the connection, avoiding damage or wear of the voltage and current detection device caused by too fast pop-up.

[0015] (2) The power management integrated circuit voltage and current detection device fixes the data line by moving the clamping plate to contact the Z-shaped plate and cooperating with the wire duct and the clamping groove. By straightening the data line, it helps to reduce the mutual interference between the cables, thereby improving the signal transmission quality and ensuring the accuracy of voltage and current measurement. By moving the mounting plate upward to break away from the contact with the Z-shaped plate, the Z-shaped plate moves upward under the elastic force of the clamping spring. The upward movement of the Z-shaped plate causes the wire duct to break away from the contact with the data line. By automatically loosening the data line, it can ensure that accidental contact with the electrical connection is avoided during the disassembly of the voltage and current detection device, reducing the risk of electric shock, thereby improving operational safety.

[0016] (3) The voltage and current detection device of the power management integrated circuit generates vibration through the contact and friction between the arc panel and the arc rod. The vibration of the arc panel drives the load-bearing plate to resonate together. Appropriate vibration can help tighten the voltage and current detection equipment and reduce the possibility of loosening, thereby improving the stability of the equipment. The load-bearing plate moves in the direction close to the Z-shaped plate to contact the voltage and current detection equipment and assist in fixing the voltage and current detection equipment. The auxiliary fixation can effectively reduce the displacement of the voltage and current detection equipment caused by vibration during operation, thereby further avoiding measurement errors caused by changes in the position of the voltage and current detection equipment.

The clamping spring 147 is squeezed and deformed by the Z-shaped plate 143 and accumulates force. At the same time, the Z-shaped plate 143 moves downward and contacts with the clamping plate 146. When it is necessary to tidy up the data line between the voltage and current detection device 9 and the detected device, the free end of the elastic telescopic block 145 is manually pulled away from the Z-shaped plate 143. The free end of the elastic telescopic block 145 moves away from the Z-shaped plate 143, driving the clamping plate 146 to move. The clamping plate 146 moves out of contact with the Z-shaped plate 143, and the clamping plate 146 is moved to the Z-shaped plate 143. After 46 moves out of contact with the Z-shaped plate 143, the data line is placed between the clamping plate 146 and the Z-shaped plate 143.
