[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, and fixing should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.
[0020] Reference Figures 1 to 2As shown, a tamper-proof structure provided by the present utility model is applied to a POS machine. The tamper-proof structure includes: a first circuit board 1 and a second circuit board 2. Protection circuits are respectively provided on the first circuit board 1 and the second circuit board 2. A first electrical connector 11 is provided on one of the first circuit board 1 and the second circuit board 2, and a second electrical connector 21 is provided on the other. A gap is maintained between the first circuit board 1 and the second circuit board 2, and the protection circuits on both are connected to form a tamper-proof loop through the insertion of the first electrical connector 11 and the second electrical connector 21. Among them, the first circuit board 1 and the second circuit board 2 are arranged vertically or horizontally or front-to-back. In this embodiment, the arrangement between the first circuit board 1 and the second circuit board 2 is introduced as vertical. Among them, the first circuit board 1 includes any one of a flexible circuit board with reinforcement, a PCB board, and a circuit silver paste board, but is not limited to these. It can also be other structural circuit boards. In this embodiment, the first circuit board 1 is preferably a flexible circuit board with reinforcement. The second circuit board 2 includes any one of a flexible circuit board with reinforcement, a PCB board, and a circuit silver paste board, but is not limited to these. It can also be other structural circuit boards. In this embodiment, the second circuit board 2 is preferably a PCB board. One or two or three or more first electrical connectors 11 are provided, and the number is set according to needs. The number of the second electrical connectors 21 is the same as that of the first electrical connectors 11. One of the first electrical connector 11 and the second electrical connector 21 is a socket, and the other is a plug. The first electrical connector 11 is connected to the bottom of the first circuit board 1, and the second electrical connector 21 is connected to the top of the second circuit board 2. The first circuit board 1 and the second circuit board 2 are connected through the plug and the socket to form a tamper-proof loop for the protection circuits on both. When the first electrical connector 11 and the second electrical connector 21 are disassembled, the tamper-proof loop is disconnected, locking the POS and making the POS machine unusable, or destroying the stored data, thereby achieving anti-tampering and cracking. After the first circuit board 1 and the second circuit board 2 are connected through the plug and socket, the plug and socket structure can support the first circuit board 1, so that a gap is maintained between the first circuit board 1 and the second circuit board 2.
[0021] A protected structure 3 is provided on the second circuit board 2, and the first circuit board 1 covers the protected structure 3 for protecting the protected structure 3.
