The plug-in interface 101 of the electrical connector 100 is a USB Type C interface. The rear end of the electrical connector 100 receives the electronic card 200. Therefore, only one plug-in interface 101 can be connected to the USB Type C plug, and can also be used to install or remove a card. Compared with the design of the two interfaces of the interface connected with the USB Type C plug and the interface for loading and unloading the SIM card, the design of one plug interface 101 can save space. The distance between both sides of the inner edge of the outer frame 313 and the sides of the outer edge is greater than the distance between the upper and lower sides of the inner edge and the upper and lower sides of the outer edge. The two sides of the outer frame 313 are set to have a larger width to facilitate latching with the stepped portion of the electronic device 300, and also make the outer frame 313 smoothly transition to the front surface 301.
