Nowadays, it can be said that there are more and more household appliances, such as chargers for charging our mobile phones, computers that we must use in our daily work, and televisions for our entertainment at home. These are all very important household appliances. But have you really understood home appliances?
For example, the plugs on household appliances, many people don't know much about this kind of thing. Today I will introduce to you, what are the two holes at the front of the plug for?
If I don't mention it to everyone, it is estimated that many friends will not know that there are actually two small holes in the plug. Although these two small holes are very small in design, they are very useful. When we use the socket, the plug will be connected to the socket, and then the metal probe inside will be clamped with the jack in the middle of the socket. If there are no two small holes, it is likely to be loose. This approach ensures that the plug is connected more tightly, and then there is no possibility of loosening.
Some friends will ask, why is it necessary to adopt such a design method? In fact, it has a lot of design uses, such as friends with the elderly and children at home. We adopt this design method in our own home to ensure that there will be no hidden danger of electric shock and the safety of children. The design method performance is very high.
