Description
Technical field
The utility model relates to a kind of IC-card seat operator guards, belongs to electronic equipments safety protection field, particularly smart card security protection field.
Background technology
IC-card is in the process of carrying out real trade, and likely reveal sensitive information is the I/O pin carrying out transfer of data, and I/O pin is arranged near IC-card socket side usually, is easily detected and steals data message; The existing guard method for I/O pin mainly adopts the PCB patch plate being provided with safety signal at IC-card spigot, and adopts the protection of this kind of structure, and cost is high, and volume is large, is unfavorable for the miniaturization of electronic equipment.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of novel structure, the IC-card seat operator guards that volume is little.
The utility model adopts following scheme to realize: a kind of IC-card seat operator guards; comprise PCB mainboard and be located at the IC-card seat above PCB mainboard; described IC-card seat is positioned on the downside of IC-card socket and offers installing hole; on front side of the I/O pin of described mounting hole site in 4 pins near IC-card socket side; a pedestal is embedded with in described installing hole; be wound with in the horizontal direction in the middle part of described pedestal and form spiral helicine wire, described wire two ends are electrically connected with the security monitoring module on PCB mainboard and form protective circuit.
Further, described wire two ends are fixed with to be welded in the pad on PCB mainboard respectively.
Further, on described pedestal to be wound around the upper edge height of wire concordant with IC-card socket downside.
Further, the axle portion being wound around wire is provided with in the middle part of described pedestal.
Further, described pedestal is universal inductor electronic device.
Further, described wire is copper cash or enamelled wire.
Compared with prior art, the utility model has following beneficial effect: this IC-card seat operator guards novel structure, and volume is little; be applicable to the IC-card socket that space is less, be conducive to the miniaturization of electronic equipment, can I/O pin on available protecting IC-card seat; avoid data message to reveal, fail safe is high.
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the utility model will be described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment organigram;
Fig. 2 is IC-card seat cutaway view in the utility model embodiment;
Fig. 3 is A-A profile in Fig. 2;
Number in the figure illustrates: 1-PCB mainboard, 2-IC deck, 3-IC card plug, 4-installing hole, 5-contact, 6-I/O pin, 7-pedestal, 701-axle portion, 8-wire, 9-pad.
Embodiment
As shown in Fig. 1 ~ 3, a kind of IC-card seat operator guards, the IC-card seat 2 comprising PCB mainboard 1 and be located at above PCB mainboard 1, described IC-card seat 2 is positioned on the downside of IC-card socket 3 and offers installing hole 4, described installing hole 4 is elongated hole, and the length direction of installing hole 4 is parallel with the Width of IC-card socket 3; On front side of the I/O pin 6 of described mounting hole site in 4 pins near IC-card socket side, a pedestal 7 is embedded with in described installing hole 4, be wound with in the horizontal direction in the middle part of described pedestal 7 and form spiral helicine wire 8, described wire is copper cash, enamelled wire or other wire ropes; Described pedestal 7 is universal inductor electronic device; Described wire 8 two ends are electrically connected with the security monitoring module on PCB mainboard 1 and form protective circuit; the wire 8 be wrapped on pedestal 7 is adopted to form inductance; inductance there is safety signal; if directly to the attack method of IC-card socket boring etc. and so on; inductance can be caused to damage; wire on inductance can break; protective circuit just can disconnect thus the clear operation of log-on data; with protected data safety; simultaneously because the volume of inductance is little; be applicable to the IC-card socket that space is less, be conducive to the miniaturization of electronic equipment.
IC-card is in the process of carrying out real trade; the likely I/O pin 6 of reveal sensitive information; and the contact of I/O pin 6 is normally located near IC-card socket 3 side; easily be stolen information; thus the inductance of band safety signal is set on front side of I/O pin 6, can available protecting data message, as long as I/O pin 6 will be protected; other pins need not be protected, can be effectively cost-saving.
In the present embodiment, the number of described installing hole is 1 or 2, but is not limited to this; Described wire 8 two ends are fixed with the pad 9 be welded on PCB mainboard 1 respectively.
In the present embodiment, on described pedestal 7 to be wound around the upper edge height of wire 8 concordant with IC-card socket 3 downside, highly too high, easily causing IC-card socket to add glue region can break; And if highly too greatly, then do not have protective effect.
In the present embodiment, the axle portion 701 being wound around wire 8 is provided with in the middle part of described pedestal 7.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
