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.
Description
technical field [0001] The invention relates to a plug-in board, in particular to an intelligent plug-in board with automatic power-off in short circuit. Background technique [0002] Chinese invention patent (notification number: CN206098855U) discloses a kind of short-circuit automatic power-off board, realizes the function of short-circuit power-off by installing air switch in the board. [0003] However, the volume of the air switch is large, and the integration into the plug board will inevitably cause the overall structure of the plug board to become larger, making it difficult to place, carry and transport the plug board, and the price of the air switch is relatively expensive. manufacturing cost. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a smart plugboard that automatically cuts off the power when short-circuited, and has a simple and compact structure that is easy to carry and...
