The invention discloses an electric connector. The electric connector comprises an insulator body and multiple electric conduction terminals installed on the insulator body, the insulator body comprises a base portion and a tongue plate extending forward from the base portion, each electric conduction terminal comprises a first electric conduction terminal set and a second electric conduction terminal set, wherein each first electric conduction terminal set comprises a first overlap-joint terminal and a second overlap-joint terminal which are distributed in the left-right direction, the first overlap-joint terminal and the second overlap-joint terminal are each provided with a contact portion and an overlap-joint portion which is in electric connection with the contact portion, each second electric conduction terminal set comprises a first inner side terminal and a second inner side terminal which are distributed in the left-right direction, the front end of the first inner side terminal and the front end of the second inner side terminal are each provided with a contact arm, the contact arm of each first inner side terminal is located above the contract portion of the corresponding first overlap-joint terminal, the contact arm of each second inner side terminal is located above the contract portion of the corresponding second overlap-joint terminal, the rear end of each first inner side terminal is electrically overlapped with the overlap-joint portion of the corresponding second overlap-joint terminal, and the rear end of each second inner side terminal is electrically overlapped with the overlap-joint portion of the corresponding first overlap-joint terminal. Through the arrangement of the electric connector, it is favorable to lower the processing difficulty.
