Abstract

The utility model relates to the technical field of an electric connector, and particularly to a bidirectional plugging type USB electric connector. The bidirectional plugging type USB electric connector comprises an insulating body and a housing. The insulating body is provided with a tongue which extends into a socket of the housing. A first terminal and a second terminal are combined on the insulating body. A contact part of the first terminal is divided into a left sub contact part and a right sub contact part. The left sub contact part and the right sub contact part are placed on the upper side and the lower side of the tongue and are staggered from each other. The contact part of the second terminal extends and is placed on the upper side and the lower side of the tongue. The contact part of the second terminal is coordinated with the left sub contact part and the right sub contact part of the first terminal for matching with outwards electric plugging, thereby obtaining bidirectional plugging performance. The width of the socket of the housing satisfies operation requirement of coordination bidirectional plugging between the first terminal and the second terminal. The bidirectional plugging type USB electric connector facilitates use and sufficiently utilizes different points on a terminal contact part for alternate use, thereby greatly prolonging service life of the connector and obtaining high performance-to-price ratio.
