DC connectors are electrical components used to connect devices to a direct current (DC) power source. They come in various shapes and sizes, designed to ensure a secure and reliable connection. Commonly found in electronics like laptops, cameras, and power supplies, these connectors help transfer power efficiently. These connectors typically feature a cylindrical design with a central pin for positive voltage and an outer sleeve for negative. Popular types include the barrel connector and Molex connector. Proper use of DC connectors is essential for device safety and performance, preventing issues like short circuits or power loss.
