Abstract: A novel electrical connector structure is disclosed. The electrical connector includes a socket portion for receiving therein an electrical plug, a conductive terminal for clamping a metal pin of the electrical plug in the socket portion, and a wrapping portion for securing and protecting the conductive terminal in the socket portion. By designing the shape of the conductive terminal to be relatively narrow in front and relatively wide in rear, and modifying the opening shape of the socket portion accordingly, the conductive terminal can be smoothly inserted into the socket portion so as to allow the electrical connector to be easily assembled. Furthermore, the socket portion can be integrally formed because the conductive terminal is combined with the socket portion by direct insertion operation rather than conventional placing and covering operations.
