An electric coupler for a camping trailer includes a first connector, and a second connector mounted on the first connector. The first connector has a mounting groove, and the second connector has a mounting block inserted into the mounting groove of the first connector. Thus, the first connector is connected to a first electric power system, and the second connector is connected to a second electric power system, so that the trailer is connected to the first electric power system and the second electric power system respectively for use with a user. In addition, the mounting block of the second connector is inserted into the mounting groove of the first connector to combine the second connector and the first connector together so that the electric coupler is assembled easily and quickly.
