Abstract

The present invention is a safety covering design for financial transaction device, simply constructing specific solid connection between boards by the pressure formed after assembly. The pressure is formed with assembly and constructing connection of units, so illegally penetration can be easily detected, because the pressure is released by disassembly as well as the connection between boards is removed. Thus, the financial transaction device of the present invention is not easy being penetrated without alarm.

Claims

1. A safety covering design for financial transaction device, comprising:

a lower housing;

a circuit board, being disposed in the lower housing, having a plurality of first button unit and a protection circuit;

a button pressing board, being disposed on the circuit board, having a plurality of second button unit, a plurality of first contacting point and a plurality of first pressing point;

wherein each second button unit with raised surface is on the first button unit when the button pressing board is on the circuit board, and the second button unit presses the first button unit with pressure on the second button unit;

moreover, the first pressing point is conductive, and contacts the protection circuit with pressure on the first pressing point;

a first protection board, being disposed on the button pressing board, having a plurality of clamping point, a plurality of second pressing point and a first electrical circuit;

wherein each clamping point is on the first contacting point of the button pressing board when the first protection board is on the button pressing board, so the clamping points are pushed by the first contacting points of the button pressing board with pressure on the first protection board;

moreover, each second pressing point presses the first pressing point with pressure on the second pressing point, so the first electrical circuit is conductive with the protection circuit;

wherein the first electrical circuit is connected to the second pressing point;

a second protection board, being disposed on the first protection board, having a plurality of second contacting point, a plurality of first hole, a second electrical circuit and a plurality of second hole;

wherein each second contacting point is on the clamping point, and each second hole is on the second button unit when the second protection board is on the first protection board;

wherein each clamping point is pushed by the first contacting points and is contacted with the second contacting point as pressure on the second protection board and the first protection board, so the first electrical circuit is conductive with the second electrical circuit;

wherein each first hole is on the second pressing point when the second protection board is on the first protection board;

a rubber keyboard, being disposed on the second protection board, having a plurality of rubber button and a plurality of pressing column;

wherein each rubber button is on the second button unit, so the rubber button can pass through the second hole and press the second button unit, then the second button unit presses the first button unit with pressure on the second button unit;

wherein the pressing columns are formed under the rubber keyboard, and pass through the first hole; and

an upper housing, being disposed on the rubber keyboard and combining with the lower housing;

wherein the rubber keyboard is pressed by the upper housing, and the pressing columns of the rubber keyboard press the second pressing points, then the first pressing points pressed by the second pressing points contact the protection circuit, so the first electrical circuit is conductive with the protection circuit;

wherein when the clamping point and the second contacting point keep contactless, the first electrical circuit and the second electrical circuit are formed open-circuit;

wherein when the pressure on the first pressing point is released, the first electrical circuit and the protection circuit are formed open circuit.

2. The safety covering design for financial transaction device of claim 1, wherein the first contacting points is raised on the button pressing board.

3. The safety covering design for financial transaction device of claim 1, wherein a light guide plate is disposed between the rubber keyboard and the second protection board to increase pressure on the second protection board, and has a plurality of third holes and a plurality of fourth holes;

each third hole is on the first hole and each fourth hole is on the second hole when the light guide plate is on the second protection board.

4. The safety covering design for financial transaction device of claim 1, wherein the circuit board further includes a breaking detect circuit and a main processor, the breaking detect circuit connects the protection circuit, the main processor, the first electrical circuit and the second electrical circuit;

the main processor can detect open-circuit in any of the protection circuit, the first electrical circuit and the second electrical circuit through the breaking detect circuit.

5. The safety covering design for financial transaction device of claim 1, wherein the first protection board comprises flexible printed circuits.

6. The safety covering design for financial transaction device of claim 4, further including a card shield;

wherein the card shield has a plurality of clamping unit and a shield circuit, and contacts the circuit board with a zebra;

each clamping unit passes through the circuit board, and clamps on the clamping point, so the clamping points stick on the first contacting point, and the first protection board fixes on the circuit board solidly with the button pressing board;

the shield circuit connects to the breaking detect circuit of the circuit board through the zebra.

7. The safety covering design for financial transaction device of claim 6, wherein an integrated circuit card connector is able to dispose between the circuit board and the card shield.

8. The safety covering design for financial transaction device of claim 6, wherein the card shield comprises flexible printed circuits.

9. The safety covering design for financial transaction device of claim 1, wherein a plurality of cushion are disposed between the first contacting point of the button pressing board and the clamping point of the first protection board.
