Similarly, the user's hand can be inserted into the storage compartment 13, and then through the connecting port 143121 through the recessed groove 12 into the storage cavity 11 to insert or remove the SIM card slot assembly 33. Since the control switch 32 and the SIM card slot assembly 33 cannot be operated when the cover 20 closes the storage compartment 13, the internal switch is realized, and the anti-vandalism function is achieved.

[0040] To expand the warning range, multiple protective wires can be used. For example, multiple protective wires can be connected sequentially, with adjacent wires connected via a connector. The protective wire at the beginning and the protective wire at the end are connected to two terminals 311, thus expanding the warning range. The connector's structure can be designed according to actual needs. For example, the connector can have two locking ports, into which the ends of the two protective wires are inserted.
