The invention provides a remote-controlled DC socket with a current limiting function, which includes a top cover, a bottom plate, a cable, and a plug at the end of the cable. The remote-controlled DCsocket is characterized in that the socket further includes a remote control signal receiving device and a remote control communication controller; the top cover is fixedly provided with an indicatorlamp, a switch and plug fixing areas; each plug fixing area includes an upper clamp slot; and the bottom plate is fixedly provided with lower clamp slots and resistors. The technical scheme providedby the invention has a current limiting function, which reduces the risk of fire. The positive and negative poles of the jacks are in different shapes, so that reverse insertion of the plug is eliminated. The communication control device is added, which enables users to remotely control the opening and closing of a patch panel.
