Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a charging device and a notebook computer using the charging device. Background technique [0002] Current chargers, especially for notebook computers, generally consist of a power cord and a charger body. The power cord of the laptop charger and the PCB board in the main body of the charger are directly welded by electric welding or manual welding, which is inconvenient to install, has low bonding strength, and is not reliable. The main failure mode of the notebook charger is that the connection between the power cord and the main body of the charger is cracked. After long-term use, it is easy to cause the power cord to leak or break, resulting in potential safety hazards. Affect the life of the charger. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a charging device, which aims to improve the safety and stability of the ...
