A socket base and universal jack is a type of electrical connection system. It is used to provide a secure connection between two or more electrical components or devices. The socket base is typically mounted on a wall or other surface, and the universal jack is a modular plug that fits into the socket base. This type of connection is often used in audio and video equipment, such as amplifiers, speakers, and televisions. It can also be used to connect computers, printers, and other electronic devices.
