Abstract
The invention discloses a kind of POS machine massage protection architecture and based on this POS machine; including pcb board, metal dome and button; the pcb board is equipped with key protection circuit; FPC wire winding layers and silver slurry layer are equipped between the pcb board and button; silver paste layer avoids the button equipped with several vias; the FPC wire winding layers are embedded with coiling, and the coiling is electrically connected with the protection circuit, and silver paste layer is electrically connected with the protection circuit.The POS machine includes above-mentioned POS machine massage protection architecture.The present invention between pcb board and button by being arranged FPC wire winding layers and silver slurry layer, by silver slurry layer and FPC wire winding layers in safe coiling using together with being above effectively combined, the defect of silver paste film and FPC coilings in this kind of circuit use is evaded simultaneously, the protection for more perfectly having accomplished key area improves the security performance of POS machine.
Description
Technical field
The present invention relates to POS machine safety shield more particularly to a kind of POS machine massage protection architecture and based on this
POS machine.
Background technology
With the development of e-payment technology, POS machine is as a kind of point-of-sale terminal with clearing of account function, extensively
It is general to apply in places such as supermarket, chain store, hypermarket, restaurants.In order to ensure the debt safety of holder (consumer), POS machine
Safeguard protection design is had, i.e., dismantles POS machine in criminal, POS machine is reequiped by the tools such as boring, visiting, and
When the device of holder's card number, password is stolen in increase, POS machine detects automatically, and can be locked to POS programs.POS safety
Design protection is core technology indispensable in POS machine.
Traditional POS machine massage protection mode usually has following 2 kinds：
1, what existing coiling protection used anti-tears coiling line width and line spacing that silver paste film coiling uses since technical problem is more
For 12mil, and characteristic is torn since it is anti-, cannot be covered on button pot son, just will appear circuit during otherwise pressing
Fracture there is in the buttons security protection such as POS larger be easy to crack defect in this way.
2, FPC coilings can make multilayer and its coiling and winding department are away from can accomplish very little, as a consequence it is hardly possible to be flown
Line short circuit and its plank circuit good toughness, broken string phenomenon will not occur in arbitrary distort during use.But since its toughness is strong
It spends, when edge treated, which is easy to be rolled-up, can be inserted into shorting stub short circuit protection circuit.There is also defects for safety
Invention content
In order to solve the above-mentioned technical problem, the object of the present invention is to provide a kind of POS machine massage protection architecture and based on this
POS machine, to solve single, the insufficient technological deficiency of security performance in a manner of existing POS machine massage protection.
The technical solution adopted in the present invention is：A kind of POS machine massage protection architecture, including pcb board, metal dome and
Button, the pcb board are equipped with key protection circuit, and FPC wire winding layers and silver slurry layer, institute are equipped between the PCB plates and button
It states silver slurry layer and avoids the button equipped with several vias, the FPC wire winding layers are embedded with coiling, the coiling and the guarantor
Protection circuit is electrically connected, and silver paste layer is electrically connected with the protection circuit.
Further, further include double faced adhesive tape, the FPC wire winding layers are fixedly connected by double faced adhesive tape with silver paste layer.
Further, the FPC wire winding layers are multi-layer FPC.
Further, the coiling is connect by golden finger, pot son or carbon granules with protection circuit.
Further, silver paste layer is connect by golden finger, pot son or carbon granules with protection circuit.
A kind of POS machine, including above-mentioned POS machine massage protection architecture.
The beneficial effects of the invention are as follows：The present invention by the way that FPC wire winding layers and silver slurry layer are arranged between pcb board and button,
By silver slurry layer and FPC wire winding layers in safe coiling using together with being above effectively combined, at the same evaded silver paste film and FPC around
Defect of the line in this kind of circuit use, has more perfectly accomplished the protection of key area, has improved the security performance of POS machine.
Description of the drawings
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is the explosive view of POS machine massage protection architecture in the present invention.
Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
As shown in Figure 1, a kind of POS machine massage protection architecture, including pcb board 1, metal dome 2 and button 3, the PCB
Plate 1 is equipped with key protection circuit, and FPC wire winding layers 4 and silver slurry layer 5, silver paste are equipped between the pcb board 1 and button 3
Layer 5 avoids the button 3 equipped with several vias 6, and the FPC wire winding layers 4 are embedded with coiling, the coiling and the protection
Circuit is electrically connected, and silver paste layer 5 is electrically connected with the protection circuit.The FPC wire winding layers 4 pass through double faced adhesive tape 7 and institute
Silver slurry layer 5 is stated to be fixedly connected.The double faced adhesive tape 7 also is provided with and 6 one-to-one through-hole 8 of the via.
Prevent tearing in conjunction with silver slurry layer 5 and the advantage and disadvantage of FPC wire winding layers 4, advantage complementation such as combine the advantages of the two
It then effectively can perfectly carry out the protection of key area together, the present invention is by 3M strengths rubberizing (double faced adhesive tape 7) by silver paste
Layer 5 is bonded together with 5 strength of FPC wire winding layers, and FPC wire winding layers 4 use multilayer winding, single side young by golden finger/pot
Or carbon granules is linked with button or protection circuit, silver slurry layer 5 is avoided in golden finger/pot son/carbon granules region of FPC and periphery surrounds
It prevents from being lifted detection.Silver slurry layer 5 is linked by carbon granules/pot son and protection pad/golden finger of PCB simultaneously.Thus formed
More perfect preventive means.
It is further used as preferred embodiment, the FPC wire winding layers 4 are multi-layer FPC.
It is further used as preferred embodiment, the coiling is connected by golden finger, pot son or carbon granules with protection circuit
It connects.
It is further used as preferred embodiment, silver paste layer 5 passes through golden finger, pot son or carbon granules and protection circuit
Connection.
