So as to monitor whether that the action of next step protection information is made in extraneous abnormal destruction behavior, extraneous acquisition key message is prevented, it is real
It is more safe and reliable now to the protection of magnetic head signal.
Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings:
Fig. 1 is a kind of structural decomposition diagram of POS magnetic head safety guard embodiment of the utility model.
Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
Fig. 1 is a kind of structural decomposition diagram of POS magnetic head safety guard embodiment of the utility model, such as Fig. 1
It is shown, a kind of POS magnetic head safety guard, including magnetic core iron-clad 1, magnetic head PCBA board 2, FPC plates 3, metal dome 4 and PCB
Baffle plate 5.There is groove, the magnetic head PCBA board 2 is placed in the groove of magnetic core iron-clad 1, the FPC on the magnetic core iron-clad 1
Plate 3 to be welded in magnetic head PCBA board 2 realized with PCBA board 2 and is electrically connected with, and the PCB baffle plates 5 are welded on FPC plates 3 and FPC plates
3 realize being electrically connected with, and the metal dome 4 is close to be arranged between FPC plates 3 and PCB baffle plates 5, and PCB baffle plates 5 are connected for triggering
Internal layer two physical switch protective wires.The internal layer of the FPC plates 3 is provided with magnetic head signal wire, the top layer of the FPC plates 3
Set and the top layer of PCB baffle plates 5 is surrounded with safety signal protective wire(Not shown in figure), the internal layer setting of the PCB baffle plates 5
The top layer for having two physical switch protective wires, the PCB baffle plates 5 has two contact points(Not shown in figure), two contact points
Drawn by two physical switch protective wires respectively, when PCB baffle plates 5 are installed in magnetic head protection device of the present utility model, meeting
Pressing metal dome 4, two contact points are contacted with metal dome 4, form the physical switch protective wire conducting of Continuity signal, i.e., two.
Also including magnetic head CPU, the magnetic head CPU is arranged on a kind of POS magnetic head safety guard of the utility model
In PCBA board 5, the magnetic head CPU is electrically connected by FPC plates 3 and metal dome 4 with the physical switch protective wire of the internal layer of PCB baffle plates 5
Connect.After PCB baffle plates 5 are installed in magnetic head protection device, metal dome 4 is pressed, the two physical switch protection in PCB baffle plates 5
Line forms Continuity signal, and now whether magnetic head CPU to start lasting real-time monitoring this Continuity signal abnormal, when extraneous someone disassembles magnetic
