Abstract: A connector structure comprises a base, a D connector arranged at one portion of the base and a plurality of audio connectors arranged transversely another portion layer of the base, wherein the audio connector comprises a metal frame arranged on the mounting hole of the base, a metal pipe looped with plastic ring having identification color riveted to the metal frame, and a ground plate sandwiched therebetween. The ground plate is firmly arranged between the metal pipe and the metal frame. The contact area between the ground plate and the metal frame is increased and the grounding will not be affected by the disturbance of the ground plate or the ground terminal. Moreover, the ground plate can be rotated with respect to the metal pipe to change the location of the elastic plate such that optimal contact between the elastic plate and the case can be achieved.
