Description:This post is not an advertisement, but a friendly reminder about electricity safety!
Let me elaborate on that.
If you see such goods and ** on the Internet, will you be tempted?
Figure 1
Figure 2: This is a 3C certified product, and the quality should not be bad, right?Anyway, on impulse, I placed an order and bought it.
Figure 3 Then the nightmare began, and now I still have palpitations when I think about it!
Connect the power supply, the moment you insert the plug on the socket, the thunderbolt with lightning, fortunately, there is time to open the protection, and it trips directly, so that there is no big accident!
After the shock, I couldn't figure it out, how could this be the newly bought power strip, and it was a 3C certified product?Judging from the situation at the time, it was undoubtedly a short circuit, so I was eager to know the cause of the short circuit. However, when trying to open and check, it was found that the screws used on the back were triangular shaped screws, which could not be opened with ordinary tools. So I bought a set of special tools on the Internet, and immediately opened the back cover after receiving the tool yesterday, and the moment I opened it, I was so angry that I wanted to scold my mother, the business that produced such a product, it was really innocent!This is not a strip, it is simply a fire generator. Let's take a look at the internals!
Fig. 4: The red triangle is the short-circuit burn area.
Figure 5: The circle section shows that there is no ground wire.
So far, you may not have discovered where the most dangerous place is. Let's take a closer look at Figure 4, the live wire and the neutral line are the two copper sheets that are fixed vertically, and the copper strip horizontal at each socket is only fixed by a screw on the vertical copper strip, when inserting the plug, almost every copper strip horizontal at the interface will be displaced, and the short circuit is inevitable!
It's deliberate, generally speaking, people don't be so bad, but what a retarded design!
In fact, with a little improvement, tragedy can be avoided.
Fig. 6 As long as the insulating sleeve is added to the two vertical copper sheets, the occurrence of short circuit can be completely avoided.
Hurry up to see if there is such a hidden danger in your home's plug, if there is, either improve it, or throw it away, don't take it lightly, and regret it after the tragedy!
I wish you all a harmonious and reassuring Chinese New Year!
