An electrical connector is a device used to join electrical circuits together. It allows for the easy connection and disconnection of wires or cables, facilitating the flow of electricity. Connectors come in various shapes and sizes, designed for different applications, such as in household appliances, computers, and vehicles. These connectors can be classified into two main types: plugs and sockets. A plug is typically attached to a cable and fits into a socket, which is fixed in place. Common examples of electrical connectors include USB connectors, HDMI connectors, and power plugs, each serving specific purposes in electronic devices.
