Power connectors are devices that allows an electrical current to pass through it for the exclusive purpose of providing power to a device (not a data stream, for example, or anything more complex).Electrical connectors are classified into three types based on their termination ends: board-to-board connectors, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors.
There are two main types of power connector – residential and industrial. Power connectors carry either AC (alternating current) or DC (direct current). AC connectors allow a device to be connected directly to a power supply. DC connectors typically come in standard sizes and are not interchangeable for safety reasons.
Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket. The connection may be removable (as for portable equipment), require a tool for assembly and removal, or serve as a permanent electrical joint between two points.
