Choose big brands. The quality power socket of J&S lighting, Niu Niu, Bada, Junlang and other brands are of good quality.
Because it is difficult to tell the quality from the appearance, unless it is an engineering socket, it is difficult to tell.
The quality of the socket depends on the thickness of the internal contact copper.
This is the disassembled internal structure of a high-quality socket, copper post terminals, and thickened contact copper sheets.
Above is the internal structure of a high-quality socket, which is mad-e of thicken-ed materials.
Below is the internal structure of a low-quality socket.
The copper sheet is very thin. Too much space at the contact position can easily cause heat and fire.
It can also easily cause the socket to be unable to be pull-ed out. The terminal is mad-e of two copper sheets and an iron screw.
Therefore, it is recommend-ed to choose sockets from big brands and go to physical stores to buy them.
Online shopping may not necessarily be authentic.
Nowadays, many brands have launched physical store versions and e-commerce versions at the same time to cater to the times.
The e-commerce version is actually a castrated version, and the quality power socket is definitely different.
