A connector is simply a device that acts like a temporary bridge between two things that need to connect, such as two wires or a wire and a circuit board. Its main job is to let electricity, data, or signals pass through easily. You use connectors every day when you plug your phone charger into the wall or connect a game console to your TV using an HDMI cord. Instead of permanently gluing wires together, connectors use smart designs—like plugs that fit into matching sockets—allowing you to connect and disconnect things quickly and safely whenever you need to. They come in many different shapes and sizes depending on the job they need to do, but they all make sure the right signal gets from one place to another without getting lost.
