Referring to fig. 2, the tamper module is disposed in the electronic device 100, and the tamper module includes a protection circuit (not shown) and a tamper 40.

Referring to fig. 2, in the present embodiment, there are two anti-detachment members 40, each anti-detachment member 40 corresponds to a protection circuit, and the two anti-detachment members 40 are respectively disposed at two opposite ends of the housing 10 in the length direction. When any one of the detachment prevention members 40 is separated from the circuit board 20 to cause the corresponding protection circuit to be powered off, the storage module and the circuit board 20 are powered off, and data stored in the storage module is frozen. That is to say, when the housing 10 is separated from the circuit board 20 from any end, the tamper module can perform the tamper function, and the reliability of the tamper module is further enhanced. One of the tamper evident elements 40 and its corresponding protective circuit will be described below.
Referring to fig. 2 and 3, the detachment prevention member 40 includes a main body 41 and a touch control body 42, the main body 41 includes a connecting section 43 and an elastic protection cover 44 located at one end of the connecting section 43, the touch control body 42 is disposed in the elastic protection cover 44, and the touch control body 42 includes an electrical connection end 421 facing the outside of the elastic protection cover 44. The anti-detaching element 40 is fixed to the housing 10 through the connecting section 43, the elastic protection cover 44 abuts against the circuit board 20, and the electrical conductive end 421 of the touch body 42 abuts against the protection circuit and conducts the protection circuit. When the housing 10 is separated from the circuit board 20, the touch body 42 is separated from the circuit board 20 to power off the protection circuit. In this embodiment, only the electrical connection end 421 of the anti-tamper device 40 is connected to the protection circuit, so that only the electrical connection end 421 needs to leave the protection circuit, the current loop of the protection circuit can be disconnected, and the anti-tamper sensitivity of the anti-tamper module is improved.
With reference to fig. 2 and fig. 3, the elastic protection cover 44 includes a contact peripheral surface 441, the contact peripheral surface 441 is disposed opposite to the connection section 43 and faces the same direction as the electrical connection end 421, and the contact peripheral surface 441 elastically abuts against the working surface 201 of the circuit board 20. Specifically, the main body 41 is in a horn shape, the elastic protection cover 44 is a cover body having an opening at one end, and the contact circumferential surface 441 is provided at the opening end. The touch body 42 is disposed in the cover body, one end of the touch body is fixedly connected to the bottom surface 442 of the cover body, and the other end is the electrical connection end 421. When the housing 10 is mounted on the circuit board 20, the detachment prevention member 40 is compressed, the contact peripheral surface 441 of the elastic protection cover 44 and the end surface of the electrical connection terminal 421 abut against the circuit board 20 at the same time, and the touch control body 42 is enclosed in the elastic protection cover 44. The elastic protection cover 44 protects the touch control body 42.
Further, the material of the detachment prevention member 40 is an elastic material, and the elasticity of the main body 41 is greater than that of the touch body 42. Since the removal prevention member 40 is an elastic material, it is in an elastically compressed state when it receives a pressure applied from the housing 10. When the detachment prevention member 40 is separated from the housing 10, the pressure applied to the detachment prevention member 40 by the housing 10 is reduced or eliminated, and the detachment prevention member 40 is elastically restored by the resilient force to be separated from the circuit board 20, so that the protection circuit is powered off. Meanwhile, since the main body 41 has elasticity greater than that of the touch body 42, that is, the elastic protection cover 44 has elasticity greater than that of the touch body 42. The elastic protection cover 44 is compressed to have a large elastic potential energy, when the applied pressure is removed, the elastic potential energy is released and converted into kinetic energy, and the elastic protection cover 44 deforms and recovers to be bounced off the circuit board 20, so that the touch body 42 is driven to leave the circuit board 20, and the protection circuit is powered off. Therefore, the touch body 42 is prevented from rebounding to be contacted with the protection circuit again in the process of detaching and loosening the shell 10, so that the protection circuit is conducted.
The material of the main body 41 may be a thermoplastic elastomer, such as thermoplastic vulcanized rubber or thermoplastic polyurethane, or may be other elastic materials. In this embodiment, the main body 41 is made of a thermoplastic polyurethane material. Meanwhile, the main body 41 is also made of an insulating material, and when the detachment prevention member 40 abuts against the circuit board 20, only the touch body 42 is conducted with the protection circuit, and the main body 41 is not conducted with the protection circuit. That is, when the housing 10 is separated from the circuit board 20, the current loop of the whole protection circuit can be disconnected only by separating the touch body 42 from the protection circuit. The touch body 42 is not separated from the protection circuit, but the elastic protection cover 44 is still separated from the protection circuit, so that the protection circuit is still in a conducting state, and the anti-dismantling sensitivity of the anti-dismantling module is further improved. Meanwhile, as the main body 41 is made of an insulating material, the protection circuit and the housing 10 are not conducted, and the current of the protection circuit is not transmitted to the housing 10 through the anti-detachment member 40 to cause a risk of electric leakage, thereby ensuring the safety of the electronic device 100.
Referring to fig. 2 and fig. 3 again, the touch-control body 42 is made of conductive silicone or silicone with a conductive coating coated on an end surface of the conductive contact 421. In this embodiment, the touch body 42 is made of conductive silicone. The conductive silica gel has certain elasticity, and when external pressure is removed, the conductive silica gel is stretched under the action of resilience force, so that the touch body 42 is further accelerated to leave the circuit board 20, and a current loop of the protection circuit is quickly disconnected. Meanwhile, the conductive silica gel has conductive performance, and when the touch body 42 abuts against the protection circuit, the protection circuit can be conducted. In other embodiments, the touch-control body 42 may be made of a common silicone material, and an end face of the electrical connection end 421 is coated with a conductive coating. When the end face of the electrical connection end 421 abuts against the protection circuit, the conductive coating can conduct the protection circuit, so that the effects of saving cost and simplifying process are achieved.
Further, the protection circuit includes a control circuit region and a conductive connection circuit region (not shown), the conductive connection circuit region is electrically connected to the control circuit region and the circuit board 20, and the touch body 42 abuts against the control circuit region. Specifically, two ends of the control circuit area are respectively and electrically connected with the conductive connection circuit area, and the two ends of the control circuit area are not conducted. When the touch body 42 abuts against the control circuit region, the electrical connection end 421 of the touch body 42 connects two ends of the control circuit region, so as to connect the protection circuit. When the casing 10 is disassembled and separated from the circuit board 20, since the anti-disassembling part 40 is fixed to the casing 10, the anti-disassembling part 40 is separated from the circuit board 20 along with the casing 10, at this time, the electrical connection terminal 421 of the touch body 42 is separated from the control circuit region, the control circuit is restored to the non-conduction state at the two ends, and the protection circuit is powered off.

When the auxiliary protection circuit is disconnected, the storage module and the circuit board 20 are powered off, and data stored in the storage module is frozen, so that data and information are protected.
