Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] see figure 1 and figure 2 , the POS machine multi-layer through-hole protective cover provided by the present invention includes a protective plate 100 and two tamper-resistant switches S1 and S2 arranged on the protective plate 100 .

[0022] Specifically, the protection board 100 may be a multi-layer PCB board, including a bottom layer 110 , two middle layers 120 , 130 and a top layer 140 in sequence.

[0023] Wherein, the surface of the bottom layer 110 is used as the A side of the entire protection board 100, that is, the safe area side, which faces the main board of the POS machine and is connected to the main board. Specifically, a conductive strip PAD can be arranged on the A surface, and the conductive strip PAD passes through t...

Abstract

The invention discloses a POS machine multilayer through hole protection cover plate. A bottom layer surface is used as a safety area surface. Two anti-disassembly switches are arranged on the surfaceof a top layer and are connected to two independent anti-disassembly signals; corresponding concentric-square-shaped wires are distributed on two layers in a middle layer respectively and connected to the other two independent anti-disassembly signals; the four anti-disassembly signals are connected to a PAD on the surface of the bottom layer to be connected with conductive strips and then connected to a safety chip of a mainboard; and real-time monitoring is achieved through a protection alarm device of the safety chip. The cover plate is simple in structure and low in cost, and the safety is greatly improved.

Description

technical field [0001] The invention relates to a protection cover, in particular to a POS machine multi-layer through-hole protection cover. Background technique [0002] In order to protect safety-sensitive signals, traditional POS machines usually use protective boards to cover and protect the entire safety area to protect safety signals on the main board, including PADs, traces, vias, and resistors and capacitors of these safety signals. Existing protection boards are basically composed of multi-layer hard HDI PCBs covered by protection mesh wiring. The cost of such protection boards is high and the production cycle is long. Contents of the invention [0003] Aiming at the problems existing in the protection board scheme in the existing POS machine, a simple, safe and reliable new protection board scheme is needed. [0004] For this reason, the object of the present invention is to provide a POS machine multi-layer through-hole protective cover to overcome the existin...
