A conductive contact block 16 is provided on the inner surface of the U-shaped mounting block 15. An insulating layer 17 is provided on the outer surface of the U-shaped mounting block 15.

[0019] The conductive contact block 16 is connected to the first connecting line 7 and the second connecting line 8. The conductive block 13 is fixedly connected to the electric push rod 9 through the connecting block 12, and the conductive block 13 is movably connected to the conductive contact block 16 through the electric push rod 9.

[0020] The insulating protective sleeve 14 is bonded to the outer surface of the conductive block 13, and the insulating protective sleeve 14 is movably connected to the insulating layer 17.

[0024] Working principle

[0025] When the charger assembly 4 finishes charging the laptop, the PLC controller 5 receives a full charge signal from the laptop and controls the electric push rod 9 to retract, causing the conductive block 13 to separate from the conductive contact block 16 inside the U-shaped mounting block 15, thus cutting off the power to the charger assembly 4. However, when the laptop's battery is too low, the PLC controller 5 receives an electrical signal and controls the electric push rod 9 to extend, causing the conductive block 13 to move into the U-shaped mounting block 15 until the conductive block 13 contacts the conductive contact block 16. Then, the two-section connecting wire 8 and the one-section connecting wire 7 are energized, and the charger assembly 4 can charge the laptop. The insulating protective sleeve 14 and the insulating layer 17 can provide insulation protection to prevent leakage and short circuit.
