The invention discloses an intelligent
plugboard capable of automatically being powered off during
short circuit. The intelligent
plugboard comprises a shell, wherein a jack is arranged in the shell,a conductive core and a switch mechanism are fixedly arranged in the shell, the conductive core is corresponding to the jack, the switch mechanism is used for controlling on / off of the conductive coreand comprises a self-locking switch, a button and an open-circuit mechanism, the button is used for controlling the self-locking switch, the open-circuit mechanism is used for pressing the button during
short circuit and comprises a permanent
magnet, an
electromagnet, a guide rod and a first spring, a guide groove is formed in the
electromagnet, the guide rod is arranged on the guide groove in asliding way, the permanent
magnet is fixed at one end of the guide rod and is connected with the button, and when a current of the conductive core exceeds a preset value, the permanent
magnet is pushed to shift the button by the
electromagnet and the self-locking switch is disconnected. By the structure of the button, the electromagnet, the permanent magnet and self-locking switch, the power-off function during
short circuit is achieved, and the intelligent
plugboard is simpler and more compact in structure, the integral volume is reduced, and the plugboard is convenient to carry.
