As an accessory product for industrial production of electrical source parts, the main function of the terminal is to facilitate the connection of wires. However, in the process of industrial development, it is also divided into the range of connectors, which means that it is an important accessory for industrial production. The role of the connector is the same as that of the connector, which is convenient for production, and is beneficial to improve production efficiency as the main purpose. At the same time, it is a must for production development. According to the process of industrialization, wire connection and signal transmission have already been realized, but how to ensure the transmission process is the purpose of designing the terminal, that is, the important role that the terminal should play.
