The outer appearances of the connectors are also maintained by preventing marks, due to the insertion and extraction. The electrical connector assembly comprises the receptacle connector and the plug connector. The receptacle connector and the plug connector respectively comprise locking portions that lock to each other with a low engagement holding force during engagement. The receptacle connector further comprises press contacting protrusions, for frictionally contacting the plug connector, and serves to prevent extraction.
