Line switching type input signal interface terminal block used on modularized assembling seat

The utility model relates to the field of intelligent manufacturing equipment, in particular to a line switching type input signal interface terminal block used on a modularized assembling seat, which comprises an insulating base and a clamping plate on the back surface of the insulating base, round hole plug wire interfaces, inlet and outlet wiring ports and sensor input signal plug wire terminals which are electrically connected are fixedly arranged in front of the insulating base, one or more groups of inlet and outlet wiring ports are arranged, and the inlet and outlet wiring ports are numbered in sequence; and the sensor input signal plug wire terminal is connected with a relay through a signal input wire. The design reorganizes the disorder of the lines, so that the lines become tidy, and almost few open lines are seen on a machine table, so that the operation table becomes tidy. During installation, due to the modularized assembling seat, the mechanical function module is arranged on the modularized as
