Referring to FIG. 6, a first mesh line 270 formed inside the outer protection PCB 200 is electrically connected to the input terminal 155 and the output terminal 157 of the main PCB 100, and the cover PCB ( The second mesh line 410 formed inside the 400 may be electrically connected to the terminals 151 and 152 of the main PCB 100 through the zebra connectors 350 and 360.

When the security device 10 of the electronic device described above is forcibly dismantled, the electrical connection between the mesh lines 270 and 410 and the terminals 151, 152, 155 and 156 is blocked. Specifically, when the cover PCB 400 is forcibly disassembled, the electrical connection between the second mesh line 410 of the cover PCB 400 and the zebra connectors 350 and 360 is cut off, and the terminal of the main PCB 100 ( The electrical connection between 151 and 52 is cut off. In addition, when the outer protection PCB 200 is forcibly dismantled, electrical connection between the first mesh line 270 and the terminals 155 and 156 of the main PCB 100 may be blocked. In this way, when the authority access is blocked, the control unit in the information terminal 110 may delete input information and transmit an alarm signal to the user terminal.

Meanwhile, the outer protection PCB 200 is coupled to the main PCB 100 and the cover PCB 400 through hooks 251 to 254 and insertion protrusions 261 to 264.

In order to steal information stored in the electronic device security device, someone can release the fastening screw 50 and access the information terminal 110 through the fastening holes 127, 345, and 451. To this end, the security of the zebra connector 350 must be released. In this case, a bypass circuit may be formed at the terminals 151 and 152 of the main PCB 100 to attempt to release the security of the zebra connector 350.

A blocking block 500 is provided to fundamentally block an attempt to release the security of the zebra connector 350 described above. The blocking block 500 physically blocks access to the zebra connector 350 through the fastening holes 127, 345, and 451. In addition, when the blocking block 500 is physically removed, the electrical connection between the blocking block 500 and the main PCB 100 is released, and an alarm signal may be transmitted to the user terminal. On the other hand, it may be attempted to release the security of the blocking block 500 by forming a bypass circuit in the blocking block 500, but the connection terminals 504 and 505 of the blocking block 500 are provided with fastening holes 127, 345, and 451. Since it is provided to the zebra connector 350 side rather than the) side, it is impossible to form a bypass circuit with the connection terminal.
