A plug 4 is provided on the socket 3, and the socket 3, the plug 4 and the rear seat 2 are integrally formed. When the socket 3 is inserted into the receiving chamber 101 from the rear port of the housing 1, the plug 4 is also placed in the receiving chamber 101. Among them, the Type-c connector further includes a terminal 41, and the terminal 41 is integrally formed with the rear seat 2, the socket 3 and the plug 4. One end of the terminal 41 extends to the plug 4, and the other end extends to the outside of the rear seat 2. The connector of the data cable is inserted into the receiving chamber 101 from the front port of the housing 1 to contact the terminal 41 on the plug 4. The terminal 41 extending to the outside of the rear seat 2 is welded to a circuit board (not shown in the figure). And, a positioning post 21 for positioning the welding position is provided on the rear seat 2. The position of the rear seat 2 and the circuit board is positioned by the positioning post 21, so as to facilitate the subsequent welding process of the terminal 41 and the circuit board.
