A track circuit branching device relates to a track short-circuit prevention device and solves the problem that the existing branch lines have fewer contacts with a track face, and no branch line state indication or in-use state management. The track circuit branching device comprises a branch line and a management box, two ends of the branch line are connected with a main connector and an auxiliary connector box respectively, each of the main connector box and the auxiliary connector box comprises a track face connector, an outer casing is fixed on the upper portions of the track face connectors, a detection circuit board is further arranged in the main connector box and mounted on the track face connectors, a constant current source, a voltage testing loop and a status indicating lamp are arranged on the detection circuit board, a detection switch and a battery are further arranged on two sides of the detection circuit board and on the track face connectors respectively, contact pins are arranged below the detection switch, charging shoes are arranged below the battery, and a test line is further arranged between the main connector box and the auxiliary connector box. The track circuit branching device in multi-point contact is stable in contact, and capable of timely displaying statues of the branch line and detecting the in-use status of the branch line so as to guarantee reliable branching of a track circuit.
