Abstract

Provided is a card edge connector, comprising an insulation body and two latching devices, wherein each latching device comprises a main body, a first interconnecting piece, a second interconnecting piece, with the second interconnecting piece being located in front of the first interconnecting piece, and a weld part, wherein one side of the weld part, close to the main body, bends upward and extends to form a separation blade; and the second interconnecting piece extends downward to form a spacing portion, with the spacing portion located over the weld part and pushing against the joint of the separation blade and the weld part. As the separation blade is directly formed by the bending and extension of the weld part, the separation blade has great rigidity and is unlikely to rupture due to serious deformation caused by external force. Moreover, as the spacing portion is located over the weld part and to push against the joint of the separation blade and the weld part, the stopping intensity of the separation blade over the spacing portion is very strong, and accordingly the latching device is unlikely to be worn-out due to the overlarge deformation of the main body and the spacing portion.
