Embodiment
By describing technology contents of the present invention, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, in present embodiment, Contact Type Ic Card card swiping terminal comprises control circuit board 1, IC-card slot 2 and IC-card radome 3.
Control circuit board 1 is placed with various electric components according to the functional requirement of this card swiping terminal and is connected by printed circuit, each electric components is chosen according to actual functional capability demand and is designed, and does not carefully state one by one herein.IC-card slot 2 is fixed on control circuit board 1, wherein, is provided with the metal contact piece (not shown) for contacting with IC-card in IC-card slot 2, this metal contact piece to control circuit board has corresponding circuit connecting relation to realize IC-card function of swiping card.
IC radome 3 comprises conductive fabric 31, and IC-card radome 3 covers on IC-card slot 2, and conductive fabric 31 is electrically connected to ground (GND) end of control circuit board 1.Wherein, it is the region easily producing electrostatic as the sensitizing range of IC-card slot 2 that IC-card radome 3 covers the scope of setting, and is generally the spatial dimension of metal contact piece and surrounding 10mm thereof.
As shown in fig. 1, the ground end of control circuit board 1 is arranged at the side of IC-card slot 2, and conductive fabric 31 arranges lug 311, and lug 311 is bonded in the ground end of control circuit board 1 and realizes electrical connection.For the connection making conductive fabric 31 and ground hold is more reliable, also plastic member is provided with in Contact Type Ic Card card swiping terminal, plastic member is pressed on lug, this plastic member can be shaped in card swiping terminal housing on also can be that individual member is fixed on housing, when control circuit board is fixed in housing, plastic member is pressed on lug place.Because plastic member is insulation, therefore can ensure that housing is not charged while making conductive fabric and ground hold reliable connection, use safety.
In this Contact Type Ic Card card swiping terminal, owing to establishing the IC-card radome of band conductive fabric in IC-card slot outside mask, when producing electrostatic when swiping the card, conductive fabric can be dredged electrostatic, and to be electrically connected earth terminal due to conductive fabric, electrostatic effectively can be dredged to ground through conductive fabric, prevents electrostatic from producing other components and parts of control circuit board and attacks, effective filtering is swiped the card the electrostatic interference that process produces, and improves the security of card swiping terminal.
Consult Fig. 2, be bonded with the first plastic foil 32 and the second plastic foil 33 respectively in conductive fabric 31 both side surface, wherein, the first plastic foil 32 area is less than conductive fabric 31, the second plastic foil 33 and conductive fabric 31 sizableness.The material of two plastic foils preferably adopts PET material.The Main Function of two plastic foils is to prevent conductive fabric from contacting with circuit components.When IC-card radome 3 covers on IC-card slot 2, the first plastic foil 32 is positioned at inner side and directly fits with IC-card slot 2, outside the second plastic foil 33 is then positioned at.Illustrate in Fig. 2 for conductive fabric 31 and the second plastic foil 33 are expanded into the figure after plane, when actual mask is located on IC slot 2, conductive fabric 31 and the second plastic foil 33 cover the sidewall of also folding coated IC-card slot 2 after IC slot 2 upper surface.
First plastic foil 32 covering metal contact region makes metal contact piece and conductive fabric 31 isolate, and can prevent conductive fabric 31 contacting metal contact from causing short circuit between metal contact piece like this.Because the first plastic foil 32 area is less than conductive fabric 31, electrostatic is still effectively effectively dredged to conductive fabric 31.For obtaining better Anti-static effect, the area of the first plastic foil 32 should be as far as possible little on the basis of covering metal contact.
Second plastic foil 33 mainly prevents conductive fabric 31 from contacting with other components and parts on control circuit board 1 and causes short circuit, therefore its size is suitable with conductive fabric 31, except the lug 311 of conductive fabric 31, second plastic foil 33 covers conductive fabric 31 substantially completely, make IC-card radome 3 outside surface be essentially insulation, can to ensure like this can not provide electric connection path to other components and parts.
For verifying technique effect of the present invention, for POS, based on " GB GB/T17626.2-2006 ", test in conjunction with industry requirement:
As shown in Figure 3, on an IC-card, draw each contact (metal contact piece) in POS in IC-card slot with fly line, electric discharge instrument is adjusted to " CONTECT " pattern; Discharge 10 times in each contact, before electric discharge, by model machine " eventually inspection "; Often beat 10 times, with the electric charge on conduction brush removing IC-card, and positive and negative switching; Occur in process " restart " or " deadlock " after, stop electric discharge; Sparking voltage is started to walk from 2KV, increases progressively 1KV at every turn, till getting " attack ".Two kinds of situations when adding IC-card radome and do not add IC-card radome are tested respectively at same model machine.
Test record is as shown in the table.
Experimentally result is obviously found out, after adding IC-card radome, model machine can bear higher electrostatic potential, and model machine antistatic effect significantly improves.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
