Connectors are a type of electrical component that are used to join two or more electrical circuits together. They are commonly used in electronics to join the printed circuit board to wires and other components. They allow the electrical current to pass through them without resistance, and they provide a secure physical connection that is usually not available with just a soldered connection. Connectors come in a variety of shapes and sizes and are used in varying applications such as data and power supply connections, audio connections, and even as a means to splice wires together. Connectors are designed to be reusable and can be easily removed if needed.
