Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrical connection, and particularly to a lightning protection plug.
Background Art
[0002] When a power supply receives a high-voltage surge generated by induced lightning current, it will damage various electrical equipment. In particular, the threat to electrical equipment in use is the greatest. The dedicated power adapter for lightning protection used in the prior art for electrical products has discharge tubes or lightning protection elements connected to the positive and negative electrical contact pieces corresponding to the insertion port respectively, and these discharge tubes or lightning protection elements are connected to the ground terminal. Although the high-voltage induced lightning current in the power supply can be drawn into the ground for discharge, it cannot be effectively grounded or cannot play a protective role in the case of poor grounding. On the other hand, when the lightning protection element that does not use a discharge tube deteriorates, it is easy to cause a phenomenon of short circuit between the live wire and the neutral wire. And it is costly and inconvenient to use.
