Sockets and Insulators may seem mundane, but they play a vital role in electrical engineering and everyday life. Sockets are an important bridge between electronic devices, providing a physical interface that allows different devices or cables to transmit electrical signals or data through standardized contact points. The jack not only simplifies the connection process between devices, but also ensures the stability and efficiency of signal transmission. Its role is to achieve reliable flow of power, signal or data through precisely designed contact points and structures, while supporting rapid plug and pull, easy maintenance and upgrade of equipment. Insulators are materials that block the passage of electric current and play a protective role in electrical engineering. With its high resistance characteristics, the insulator can effectively isolate the current, prevent current leakage or short circuit, and ensure personal safety and stable operation of the equipment. Its role is not limited to preventing electric shock, but also includes reducing electromagnetic interference and improving circuit efficiency.
