Simulation I-type concentrator

The utility model relates to the technical field of power grid training tools, and discloses a simulation I-type concentrator, which comprises a main body, a liquid crystal screen arranged on the main body, an infrared communication device arranged on the main body, an RS232 communication port arranged on the main body, a USB interface arranged on the main body, a wiring terminal strip arranged on the main body, and twelve threaded grooves arranged on the wiring terminal strip. The inside of each threaded groove is in threaded connection with a screw, and the corresponding connecting groove can be exposed by rotating the movable plate, so that a user can insert a wire to be connected into the connecting groove so as to connect the wire with the terminal, then the wire is bent, and then the movable plate is rotated and moved to return to the original position. In this way, the movable plate can extrude the bent position of the wire, the wire can be fixed, the wire can be rapidly connected, when the wire needs
