The material structure material arrangement can be roughly divided into materials such as bakelite, ceramics, plastics, etc. The component name of the socket is mainly composed of: socket head (socket heads vary in standards across countries). The power cord has different lengths, generally not shorter than 1.5 meters. The material of the power cord core is copper wire, and its cross-sectional area depends on the number of sockets. The more holes, the thicker the wire. The ampere parameter of the fuse and the number of socket holes are also directly proportional to the development direction. With the rapid growth of standby energy consumption of electrical products, households and society have paid too much price. A survey conducted by the China Energy Conservation Certification Center on household standby energy consumption shows that standby energy consumption accounts for about 10% of household electricity consumption. Taking televisions as an example, the average standby energy consumption of each television is 8.07W, According to the daily standby time of 2 hours, it consumes approximately 0.016 kWh of electricity. The resource and environmental issues caused by standby energy consumption are increasingly receiving widespread attention from society. Therefore, the International Energy Agency has proposed the "1 watt plan" and will implement the 1 watt standby energy consumption action by 2010. This plan has received positive responses from the European Union and the United States, and has signed agreements promising to reduce standby energy consumption year by year. Each country has implemented mandatory regulations (such as the European Commission officially launching the "European Rational Energy Plan" in 2003, the European Union issuing the "Green Paper on Energy Efficiency" in June 2005, and the United States implementing the "White Label Mechanism" in 2006)
