Power plugs can be roughly divided into conversion power plugs, injection power plugs and assembly power plugs.
Conversion power plug: The power plug standard of each country is different. For example, the power plug from China cannot be used when it arrives in the United States. A conversion plug must be required to complete the conversion. This requires the conversion of the power plug. The conversion power plug is to convert a national standard plug into another national standard power plug.
Injection-molded power plug: An injection-molded plug means that the plug and the cord are pressed together through high temperature and high pressure. Once formed, they cannot be assembled or disassembled. Such a power plug has obvious characteristics, stability and safety. More than 80% of the power plugs generally circulating in the market are such power plugs.
Assembling the power plug: Assembling the plug means that the power cord and the plug are fixed together by screws, but they can be assembled and disassembled during use, which ensures the flexibility of the power plug. For example, a large proportion of the British market uses such assembled power plugs.
