A connector comprises an insulation body, a plurality of signal terminals, a power terminal and an earthing terminal; the insulation body comprises a rubber core and a tongue plate extending outwardsfrom the rubber core; the signal terminals, the power terminal and the earthing terminal are fixed on the rubber core and positioned on the tongue plate; the power terminal and the earthing terminal are respectively provided with a flange, so the width of the power terminal and the earthing terminal is bigger than that of the signal terminal, thereby reducing impedance of the power terminal and the earthing terminal and allowing big current.
