[0002] A circuit breaker refers to a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances.

[0003] The function of the circuit breaker is to cut off and connect the load circuit, as well as to cut off the fault circuit. During the installation of the circuit breaker, the wires need to be fixed with bolts and pressing plates. However, the current circuit breakers cannot protect the bolts. Some bolts are energized. When users open and close the circuit breaker, their hands are likely to come into contact with the bolts, which may cause the risk of electric shock and pose certain safety hazards.

[0004] Therefore, it is necessary to redesign the circuit breaker to effectively prevent the phenomenon that it cannot prevent accidental touch. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the purpose of the utility model is to provide an anti-accidental touch structure for a circuit breaker, which has the advantage of being able to prevent accidental touches and solves the problem that the current circuit breaker cannot prevent accidental touches.

[0010] As a preferred embodiment of the present invention, the front side and the rear side of the bottom of the concave tooth plate are fixedly connected to a reinforcement plate, and the right side of the reinforcement plate is fixedly connected to the surface of the pad.

[0011] As a preferred embodiment of the present invention, a metal screen sleeve is fixedly embedded in the interior of the rotating plate, and the interior of the metal screen sleeve is filled with dry particles.
