A pos safety detection switch

Abstract

The invention provides a novel protection design of a POS safety detecting switch. The POS safety detecting switch POS machine shell demounting-preventing part, a demounting-preventing conductor, a demounting monitoring switch and the demounting-preventing detecting bonding pad of a POS machine mainboard, wherein the demounting monitoring switch is located on the demounting-preventing detecting bonding pad; the demounting-preventing conductor comprises a conductive part and a sheet-shaped conductive elastic part, one end face of the sheet-shaped elastic part is a power connection face, the other end face of the sheet-shaped elastic part is a pressure-bearing face, and the conductive part is fixed on the power connection face of the elastic part through an insulating structure; when the demounting-preventing conductor is mounted on the demounting-preventing detecting bonding pad, the pressure-bearing face of the elastic part contacts with the POS machine shell demounting-preventing part, the elastic part deforms under the pressure of the POS machine shell demounting-preventing part to allow the conductive part on the elastic part to contact with the demounting monitoring switch so as to allow the demounting monitoring switch to be in a not-triggered state; when the pressure-bearing face of the elastic part does not bear pressure, the elastic part recovers to allow the conductive part to be separated from the demounting monitoring switch so as to trigger the demounting monitoring switch. By the novel protection design, the demounting monitoring function of a POS machine can be intensified, and illegal demounting can be prevented.

Description

technical field [0001] The invention relates to the field of switches, in particular to a POS safety detection switch. Background technique [0002] POS machines are commonly used in financial transactions. In order to ensure the safety of financial transactions, in the safety regulations, POS machines should have a functional design that can be destroyed when they are disassembled. This requires that the POS machines must be equipped with corresponding POS disassembly monitoring switches. However, at present The traditional design is to press the conductive carbon oil particles through the shell material to conduct the detection signal switch pad on the motherboard. However, there are risks in this design. An attacker only needs to open a small hole in the conductive carbon oil particle, inject conductive glue, and connect the detection signal switch pad on the main board to remove the POS shell without triggering the self-destruct mechanism of the POS machine. , how to so...
