Abstract

An anti-tamper device for preventing data from being tampered with by an unauthorized person includes a top cover, a bottom cover, a printed circuit board (PCB), and a signal connector. The bottom cover is assembled to the top cover. The PCB has a plurality of terminal couplers. The signal connector is fastened to the top cover, and the signal connector defines a plurality of terminal grooves. At least one of the terminal grooves receives a terminal. When the terminals are electrically connected to the terminal couplers, a first relation signal is generated to enable the anti-tamper device. When the terminals are not connected to the corresponding terminal couplers, a second relation signal different from the first relation signal is generated by the PCB to make the anti-tamper device unable to work.

Dependent claims

An anti-tamper device comprising:

a top cover;
a bottom cover detachably connected to the top cover;
a printed circuit board (PCB) fixed on the bottom cover, the PCB having a plurality of terminal couplers;
a signal connector fastened to the top cover and located between the PCB and the top cover, the signal connector defining a plurality of terminal grooves;
and
a plurality of terminals, a number of the terminals being less than or equal to a number of the terminal grooves, the terminals being received in the terminal grooves correspondingly and electrically coupled to the terminal couplers correspondingly;
wherein when the top cover is disconnected from the bottom cover, the signal connector is separated from the PCB, and the terminals drop from the terminal grooves, when the top cover is connected to the bottom cover again and the terminals are not received in the terminal grooves correspondingly, the terminals are not electrically connected to the terminal couplers correspondingly and the anti-tamper device is unable to work.
