Compared with the previous cases of various manufacturers, the specifications of the existing power plugs have become more uniform. Among them, the plugs and sockets of USB (Universal Serial Bus) specifications have become the consensus of the market. Many electronic products adopt USB specifications. As a connection medium for power and message transmission. However, the so-called unification of specifications is only compared with the past chaos. At present, the USB interface of USB specification has five versions of 1.0~3.1, and there is also miniaturized Mini-USB (also divided into A and B). With the AB model) and the Micro-USB (also divided into A, B and AB models) widely used in mobile communication devices. In addition, there are a number of electronic products that do not use the above USB specifications. When charging, they need to use their respective charging plugs to transmit power or signals. Therefore, the specifications of the power supply plugs still have certain changes.

The above problems are still a problem for consumers. In addition, for example, the vehicle electrical connectors sold in the commercial premises are generally packaged; the interfaces and various sub-models of various specifications are included to be replaced according to the requirements.
