Contact with the terminal of the plug electrical connector ensures that the power or signal is transmitted when the plug electrical connector is fully seated inside the receptacle electrical connector 100. In the case that the plug electrical connector is not fully inserted into the socket electrical connector 100, the upper row of the flat signal terminal 311 and the plug electrical connector are in poor contact, forming an incomplete contact condition. The problem of arc burning occurs.

In addition, with the quick-release hook structure, the socket electrical connector can be easily separated or assembled from the casing of the electronic product.

In addition, the window size of the panel of the outer frame is smaller than the size of the shielding shell, so that the plug electrical connector has a guiding plug when it is plugged. In addition, the corner structure around the panel is designed. When the panel is mounted on the mounting hole of the casing, the corner structure cooperates with the inner side of the mounting hole of the casing to make the casing and the panel have a smooth surface, and the casing and the panel are aligned.
