| description | The utility model discloses an electronic information technology anti-jamming device which comprises a shell, a plurality of column casings are fixedly connected to the inner wall of the shell, a circuit board is fixed among the column casings through screws, a filter is fixedly connected to the circuit board, perforated plates are fixedly embedded in the two sides of the circuit board and located in the shell, and the perforated plates are fixedly connected with the filter. The electronic information technology anti-jamming device is characterized in that the metal shell and the access door can form an electromagnetic shielding cover, air holes are formed in the outer walls of the two sides of the shell, the air holes and holes in the perforated plate are arranged in a staggered mode, and a brushless fan is fixed to the position, located on the inner wall of the shell, of one side of the circuit board through screws. The electromagnetic interference of the circuit board and the filter can be prevented, the a |
