Power adapter adopting DC jack for direct output

The utility model relates to a power adapter adopting a DC jack for direct output. The power adapter comprises a power adapter body, and the output terminal of the power adapter body is provided with a detachable DC line. The power adapter body is internally provided with a power panel and the DC jack. The output terminal of the power panel is connected with the DC jack. The DC jack is plugged into a DC output pad hole and a ground terminal pad hole, respectively, through a line end pin and a ground end pin corresponding to the output terminal of the power panel. The line end pin and the ground end pin are fixed and electrically connected with a DC output pad and a ground end pad. The two ends of the DC line are both provided with DC plugs. The DC plug of one end is used for connecting with the DC jack inside the power adapter body, while the DC plug of the other end is used for connecting with a DC jack of an input power supply end of a liquid crystal display product. According to the utility model, the maintenance cost of the power adapter is reduced and the four-point average efficiency during the calculation can be improved.
