Abstract
The utility model discloses a card edge connector, which comprises a body and a pair of locking devices. Each locking device comprises a plastic column connected with the body and a metal sheet. The metal sheet is provided with a metal elastic sheet of cantilever type. The metal elastic sheet wraps the plastic column so that the metal sheet and the plastic column can move together elastically. Due to the fact that each locking device of the card edge connector comprises the plastic column and the metal sheet wrapping the plastic column, the plastic column and the metal sheet can exert an elastic holding force on an electronic card module together so that the elastic holding force is increased. In addition, by adopting the structural design that the metal sheet wraps the plastic column, the card edge connector has the advantages of being compact in structure and small in overall dimension.
