How to avoid sparks when plugging and unplugging? Through the following three points: 1, buy a plug socket with quality assurance to ensure that the plug can withstand long-term plugging and unplugging and is not easy to loosen.

2. Buy brass phosphor copper as an insert with thick material and smooth surface.

3. Use the socket with the special hole in the new national standard, so that the contact area between the targeted plug and the socket will be larger and closer, which can effectively prevent heating and arc damage performance, and the safety performance has been greatly improved.
