A DisplayPort having protection circuit includes a supporting seat, a first terminal set, a circuit board, a second terminal set, a bottom plate and an outer casing. The supporting seat has a main body, at front of which a sealing wall is arranged. A supporting piece is extended outwardly from the sealing wall. A plurality of perforations are arranged at the supporting place between the supporting piece and the sealing wall. The first terminal set passes through the perforations and is disposed on the supporting piece. The circuit board placed in the supporting seat is electrically connected to the first terminal set. At least one protecting element is electrically connected onto the circuit board. The second terminal set is electrically connected to the circuit board. The bottom plate is assembled to the bottom part of the supporting seat. The outer casing has a hollow main body, at front of which a plugging opening is arranged. The outer casing is externally assembled and connected to the supporting seat, making the supporting piece of the supporting seat located in the plugging opening. When there is high current or surge entering the DisplayPort, the protection element can sequester the high current or surge, ensuring certain electronic parts in the circuit board without damage.
