Circuit board with electric leakage self-breaking function

The utility model relates to the technical field of circuit boards, and discloses a circuit board with an electric leakage self-breaking function, which comprises a shell. When vibration is generated, the circuit board body drives the damping spring to move so as to extrude the swing rod to swing, and meanwhile, the damping spring performs buffering, so that the phenomena that an electric leakage phenomenon easily occurs, the working performance of the circuit board is seriously influenced after long-term use, the circuit board is inconvenient to protect in the use process, and the service life of the circuit board is prolonged are avoided. Therefore, the normal use of the circuit board is influenced, and the protection effect is improved; heat generated by the circuit board body is transmitted into the cooling fins through the heat conduction pipes, internal air circulation is accelerated through the ventilation strips, and the cooling fins cool the temperature, so that the problem that the heat of the circu
