Line switching type 220V power supply interface terminal block used on modularized assembling seat

The utility model relates to the field of electrical elements, in particular to a line switching type 220V power supply interface terminal block used on a modularized assembling seat, which comprises an insulating base and a clamping plate, a 220V power supply input port, a 220V power supply output port and a wiring end which are electrically connected with one another are fixedly arranged in the front of the insulating base, the wiring end is provided with at least one group of inlet and outlet, and the clamping plate is fixedly arranged on the insulating base. The inlet and the outlet are connected to power supply equipment. One or more sets of 220V power supply interface terminal blocks are arranged on the same equipment, and the more than one set of 220V power supply interface terminal blocks are inserted into the 220V power supply input port and the 220V power supply output port through power lines to be connected in series. The design reorganizes the disorder of the lines, so that the lines become tidy,
