Socket purchase pay attention to "three look"

Look at the protection door first

Use a screwdriver or small key to pry one hole on one side and three holes on the bottom. With a bit of strength, it's unilaterally protecting the door. It's no. This socket is obviously not safe enough.

Secondly, look at copper materials

If you see it through the jack is bright yellow, then give it up. Brass is prone to rust and its texture is soft. Over time, the conductive properties are reduced. If the copper color is purple, it is better, copper is tougher, and it is not easy to rust.

It is not enough to look at it directly, but generally you must open it up. Many sockets are jacks. Copper is used here, and brass is used inside. It is also easy to rust.

Even if you use copper, you have high points. Most brands of copper pieces are several pieces of splicing, with rivets interface, so that the interface will also heat, affecting the conductivity. Compared with the current technology, the current brand will use the entire piece of copper as the copper part inside, so that the conductive performance is greatly improved.

Third, look at the distance between two or three plugs

Some products did not consider so much, two holes and three holes closer (such as the TCL Supersonic 777, Siemens vision, Smart), inserted three holes, two holes will change, because the plug is large, take the place.

These issues must be considered when buying a socket.
