A PCB or edge connector is a form of connector that mates to tracks placed on the edge of a printed circuit board, and this gives rise to its name.

The tracks shapes at the edge of the baord are specially formed to enable the connector to mate with the tracks and provide a reliable connection.The edge connector format is used in a variety of applications because it only requires the use of a single discrete conenctor - the female section because the male side is formed byt he printed circuit board itself. In this way only one conenctor is required, thereby saving considerable cost.

PCB edge connectors are commonly used in computers for expansion slots for peripheral cards, such as PCI, PCI Express, and AGP cards, etc.
