An '''edge connector''' is the portion of a [[printed circuit board]] (PCB) consisting of [[signal trace|trace]]s leading to the edge of the board that are intended to plug into a matching [[jack (connector)|socket]]. The edge connector is a money-saving device because it only requires a single discrete [[female connector]] (the male connector is formed out of the edge of the PCB), and they also tend to be fairly robust and durable. They are commonly used in computers for [[expansion slot]]s for peripheral cards, such as [[Peripheral Component Interconnect|PCI]], [[PCI Express]], and [[Accelerated Graphics Port|AGP]] cards.
