Abstract
The utility model discloses an edge connector with detachable fool-proof keys. The edge connector comprises an insulating body which accommodates a plurality of upper edge conductive terminals, a plurality of lower edge conductive terminals and at least one fool-proof key. One ends of the plurality of upper edge conductive terminals and one ends of the plurality of lower edge conductive terminals are welded on a mother circuit board, while the other ends clamp a child circuit board.
