Risk Analysis and Accident Causes of Mobile Phone Charger

Abstract

All kinds of mobile phone chargers in the actual use process, due to poor quality products or improper use will cause safety accidents, causing great harm, so this paper has great practical significance to study the use risk and accident causes of mobile phone chargers. First of all, through the failure of insulating materials between conductive parts of mobile phone charger, the use of substandard artificial plug-ins in the production of components, the use of waste circuit boards or circuit board aging, and the unqualified quality of high-frequency transformer, the use risk and reasons of inferior products are analyzed. Secondly, the risks and causes of improper use of mobile phone chargers are analyzed by analyzing the factors such as alternate mixing of different specifications of mobile phone chargers, using mobile phone while charging, and long-term plugging in the socket. Finally, three typical cases of accidents caused by the breakdown of the insulation between the conductive parts of the mobile phone charger, the excessive current at the output end, and the defects of the material are analyzed, which provides better technical support for better eliminating the hidden dangers of the mobile phone charger.
