Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-4; the utility model embodiment provides a kind of pos machine magnetic head signal protective device; comprise: FPC plate 1; one end of FPC plate 1 is connected with magnetic head 2; the other end of FPC plate 1 is connected with pcb board (not shown); the internal layer that the upper layer of FPC plate 1 is respectively arranged with mesh signal protection line 3, FPC plate 1 is provided with magnetic head signal wire 4.
In said structure, by arranging mesh signal protection line respectively in the upper layer of FPC plate, magnetic head signal wire being set at internal layer, making the parcel of mesh signal protection line realization to magnetic head signal wire.In use, if the mesh signal protection line of upper layer is destroyed, then by the control action of pcb board, the locking of POS can be realized, thus avoid the signal of POS to be attacked, and then achieve the protection to magnetic head signal.
Therefore, the magnetic head signal protective device that the present embodiment provides, by magnetic head signal is encapsulated in inside, achieves the protection to magnetic head signal.
In the present embodiment, one end of FPC plate 1 is connected with magnetic head 2 with magnetic head solder joint 6 by magnetic head decoding chip 5.
When connecting, use welding machine to be welded on magnetic head by the magnetic head solder joint of FPC plate, then the magnetic head signal of magnetic head decoding chip will transfer to magnetic head by magnetic head solder joint, realizes the communication between pcb board and magnetic head.
In the present embodiment, magnetic head decoding chip 5 is positioned on the lower surface of FPC plate 1, and magnetic head solder joint 6 is positioned at one end of FPC plate 1, and magnetic head decoding chip 5 passes through magnetic head solder joint 6 by Signal transmissions to magnetic head 2.
Adopt said structure, FPC plate and welding and the transmission of signal between magnetic head can be realized easily.
In the present embodiment, magnetic head solder joint 6 is set to 6, and interval is evenly arranged.
Magnetic head decoding chip and magnetic head solder joint are positioned on described FPC plate, and by epoxy sealing, ensure that the coherent signal of magnetic head decoding chip and magnetic head cannot be destroyed, artificially the magnetic head signal of magnetic head or decoding chip is destroyed if having, meeting preferential destruction is to the mesh signal of FPC plate, thus recognized by CPU, machine can trigger pinning.
In the present embodiment, the internal layer of FPC plate 1 comprises the first internal layer and the second internal layer from top to bottom successively, is provided with magnetic head signal wire 4 in described first internal layer and in the second internal layer.
The top layer of FPC plate is mesh signal and cabling is tight, and magnetic head signal walks internal layer, artificially destroys the magnetic head signal of FPC plate if having, and meeting preferential destruction to mesh signal, thus is recognized by CPU, and machine can trigger pinning.
In the present embodiment, FPC plate 1 is connected rear formation magnetic head cavity with magnetic head 2, fill adhesive in magnetic head cavity.
After adhesive solidifies, can seal magnetic head cavity completely, and FPC plate and magnetic head firmly be linked together, therefore, FPC plate can not be separated with magnetic head easily, avoids magnetic head signal wire to be destroyed easily.Thus further protect magnetic head signal, avoid under attack.
In the present embodiment, described adhesive can be epoxy resin.
Epoxy resin can with polytype hardening agent generation cross-linking reaction and formed and insoluble, molten not there is the cancellated superpolymer of three-dimensional, be more conducive to FPC plate firmly to stick in magnetic head cavity, better protect magnetic head signal.
By adopting technique scheme disclosed in the utility model, obtain effect useful as follows: the pos machine magnetic head signal protective device that the utility model embodiment provides, by arranging mesh signal protection line respectively in the upper layer of the FPC plate connecting magnetic head and pcb board, at internal layer, magnetic head signal wire is set, achieve the parcel protective effect of mesh signal protection line to magnetic head signal wire, and then the protection achieved magnetic head signal, therefore, the pos machine magnetic head signal protective device that the present embodiment provides, without the need to using encryption IC, both there is the effect of protection pos machine magnetic head signal, also reduce the manufacturing cost of pos machine complete machine.
