What is a power plug? Customized power plugs for different countries.
Power plug refers to the device that devices such as electrical appliances are connected to power supply. Power sockets and plugs vary in shape, class, size and type depending on the country and region. Every country has standards set by the government. The power plug is also called the power cord plug, and the English is power plug. Used in various fields, in various countries. According to the different uses of the power plug, the power cord plug can be used on voltages of 250V, 125V, and 36V. Depending on the current, it can be used in 16A, 13A, 10A, 5A, 2.5A. The frequency is generally 50/60Hz.
Classification of power plugs
Power plugs can be roughly divided into conversion power plugs, injection molding power plugs and assembly power plugs.
Convert the power plug: The power plug standard is different in each country. For example, if the power plugs from China arrive in the United States, they cannot be used, and a conversion plug must be needed to complete the conversion. This requires a power conversion plug. Converting the power plug is to convert a national standard plug into another national standard power plug.
Injection molded power plug: The injection molded plug is the plug and the wire that are crimped together under high temperature and high pressure. Once formed, it cannot be assembled and disassembled. The characteristics of such a power plug are obvious, stable and safe. More than 80% of the power plugs that are generally circulated in the market are of this type.
Assembled power plug: The assembled plug means that the power cord and the plug are fixed together by screws, etc., but they can be assembled and disassembled during use, which ensures the flexibility of the power plug. For example, a large proportion of the UK market is using this detachable power plug.
The shape and model of the power plug
Power plugs can generally be divided into 2-pin power plugs, 3-pin power plugs and multi-pin power plugs.
2-pin power plug: As the name implies, the 2-pin power plug has two pins. The specific pins are different in each country. For example, there are two inserts in China, and two round needles in Europe.
3-pin power plug: As the name implies, the 3-pin power plug means that the plug has 3 pins or two pins plus a grounding hole. Such a structure is more complicated than a 2-core power plug, and the pin size and diameter standards have great requirements. Length as well as the distance between pins are considerations.
Multi-pin power plug: This multi-pin power plug is more complicated. There are 4 cores, 5 cores, 10 cores, 20 cores… power plugs. According to the customer’s requirements, which specific device the power plug is used on should be considered according to the actual situation.
Wire color of the power plug
| North America | coordination system | IEC227 | |
| L=FireWire | black | brown | brown |
| N=midline | White | blue | blue |
| E=E=Earth wire | green | yellow-green | yellow-green |
Note: It is worth mentioning here about the connection method of the internal power cord of the Argentine plug. Since the only difference between Argentina and all countries is that the positive and negative poles are reversed, you need to pay attention.
The purpose of the power plug
Power plugs are useful for a variety of purposes and may be required in industries large and small. One sentence does not say “Where electricity is needed, there is a power plug” Visible. The purpose of the power plug and all corners of our lives.
Briefly, the following major industries:
Household appliances: The closest thing to our life is the power plug on the household appliances. TV sets, refrigerators, electric fans, air conditioners, etc. all need to be used and must use power plugs.
Communication field: usually our various communication fields also use power plugs, such as telephones, wire receiving towers, aviation equipment and so on.
All kinds of production equipment and so on used in the factory need power plugs. In short, there is still a saying: “Where there is electricity, there is a power plug.
