Abstract

The invention relates to a metal keyboard with an anti-disassembly contact point. The metal keyboard is characterized by comprising a metal panel, wherein a plastic bracket, a rubber pad, a polymer thick film (PTF) circuit board or a flexible printed circuit (FPC) board, a printed circuit board (PCB), an insulation gasket and a metal base plate are sequentially arranged below the metal panel from top to bottom; a water guide trough is formed on the plastic bracket; the PTF board or the FPC board is provided with a metal dome or carbon particles; the metal panel is tightly locked with the metal base plate through a bolt and a nut to form a whole; the contact point extends out of the rubber pad; the top part of the contact point passes through a through hole in the metal panel, and protrudes to a certain height; and the bottom part of the contact point presses the metal dome or the carbon particles on the PTF board or the FPC board. By combining the characteristics of different materials such as the metal piece, the rubber piece, the plastic material, the metal dome, the PTF/FPC board, the PCB, zebra strips and the like, a module meets financial security, an IP65 dustproof and waterproof level and an IK10 anti-explosion level requirement are met, and the metal keyboard can be prevented from being disassembled furtively and moved.

Description

technical field [0001] The invention relates to the field of EPP keyboard tamper-proof technology applied in the financial field, in particular to a metal keyboard with tamper-proof contacts. Background technique [0002] At present, ordinary metal keyboards on the market cannot meet the design requirements of financial security, cannot detect the removal of metal keyboards, and cannot meet the requirements of the People's Bank of China Testing Center for EPP keyboards. There are existing EPP-compliant keyboards and keyboards on the market, but their anti-migration technology is complex and costly, and cannot meet the waterproof, dustproof, and explosion-proof requirements of IP65 and IK10 at the same time. [0003] The technical terms appearing in the present invention are explained as follows: (1) PCB board: printed circuit board (Printed Circuit Board), also known as printed circuit board, printed circuit board; (2) PTF board: polymer thick film circuit board (Polymer Th...
