The invention discloses a fault controller cabinet device convenient for wiring. The device comprises a cabinet body, a back plate is arranged at a back side of the cabinet body, a binding post is arranged on the back plate, the binding post comprises a protective jacket, a conductive component and a clamping component; two ends of the protective jacket are the first end and the second end, and aholding space is formed in the protective jacket; the conductive component comprises an inner connection section and an outer connection section, the inner connection section is located in the holdingspace, the outer connection section penetrates through a hole on the first end and extends to the external of the holding space; the clamping component is hinged on an inner sidewall of the protective jacket through a hinge point, the clamping component comprises a clamping part and a force-carrying part, and can rotate around the hinge point and clamp or loosen the wire. The tedious steps of wiring, winding, fixing and clamping are saved, and the process of manually peeling is further saved, so that the wiring becomes simple and convenient, a user can realize the line connection by directlyplugging in a wire terminal, the connection stability is guaranteed, and the use security of the binding post is guaranteed.
