Description
[technical field]
The utility model relates to communication equipment field, especially a kind of SIM card Kato.
[background technology]
NFC (near-field communication, Near Field Communication) technology develops by contact-free formula radio-frequency (RF) identification (RFID), jointly developed by Philips Semiconductors (existing grace intelligence Pu semiconductor), Nokia and Sony, its basis is RFID and interconnection technique.Near-field communication is a kind of radiotechnics of short distance high frequency, runs in 20 cm distance in 13.56MHz frequency.Its transmission speed has 106Kbit/ second, 212Kbit/ second or 424Kbit/ second three kinds.Current near-field communication is by becoming ISO/IEC IS18092 international standard, EMCA-340 standard and ETSI TS102190 standard.NFC adopts initiatively and passive two kinds of read modes.
NFC mobile phone refers to the mobile phone with NFC module.Mobile phone with NFC module can do a lot of corresponding application.Primarily of three kinds of application models, they are mode card, NFC pattern or ad hoc mode, card reader pattern respectively.These three kinds of mode of operations are applicable to different application scenarioss.
On July 19th, 2013, Beijing company of China Mobile and municipal traffic all-purpose card Co., Ltd of Beijing sign cooperation agreement, combine issue " mobile NFC mobile phone all-purpose card " application.22, Beijing was moved financial Street, eastern Middle St, Xidan, Wangfujing etc. 37 and is changed NFC-SIM card business directly under business hall by starting to accept.From July 22, as long as hold the mobile phone supporting NFC function, and NFC all-purpose card special SIM card is installed, just can completes public transport by brush mobile phone in Beijing, subway swipes the card and the small amount payment such as supermarket food and drink.
But, also have at present a lot of mobile phone not support NFC function, even if there is NFC external equipment, how mobile phone docked with NFC external equipment and also there is technical barrier.
[summary of the invention]
The utility model provides a kind of SIM card Kato, in order to solve the problem that mobile phone cannot dock with NFC external equipment by prior art.
A kind of SIM card Kato of the present utility model, comprise: the Kato of carrying mobile terminal SIM card, the supply voltage stitch of mobile terminal SIM card, ground pin and high-voltage signal stitch are led to the outer wall of described Kato by described Kato, and form corresponding 3 contacts.
Wherein, described Kato inside comprises integrated circuit, by described integrated circuit, the supply voltage stitch of mobile terminal SIM card, ground pin and high-voltage signal stitch is led to the outer wall of Kato.
Wherein, each stitch of corresponding described mobile terminal SIM card, described integrated circuit possesses corresponding metallic contact plate, metallic contact plate described in each is equipped with salient point, and after assembling, the salient point described in each contacts with corresponding stitch; And the salient point that 3 contacts of described Kato outer wall are corresponding with described supply voltage stitch, ground pin and high-voltage signal stitch is electrically connected.
Wherein, described Kato comprises: the first panel and the second panel; Wherein, first panel comprises the groove matched with described integrated circuit, and described each Metal Contact Board position is hollow out, after assembling, described integrated circuit is embedded in described groove, and described each metallic contact plate is concordant with the first panel through described hollow out position; Wherein, the second panel comprises the groove matched with mobile terminal SIM card, and with described salient point circular hole one to one, after assembling, described salient point contacts with the corresponding stitch of mobile terminal SIM card through described circular hole.
SIM card Kato of the present utility model can solve the problem that mobile phone cannot dock with NFC external equipment by prior art.

Fig. 3 is the cut-away view of the SIM card Kato of the utility model embodiment.
[embodiment]
The SIM card Kato of the present embodiment can be shown in Figure 1 SIM card Kato front view, and the SIM card Kato using state figure shown in Fig. 2, comprise: the Kato 11 of carrying mobile terminal SIM card, the supply voltage stitch (Vcc) of mobile terminal SIM card, ground pin (GND) and high-voltage signal (VPP) stitch are led to the outer wall of Kato 11 by Kato 11, and form corresponding 3 contacts 12,13 and 14.
More preferred, the cut-away view of the SIM card Kato of the present embodiment can be shown in Figure 3, Kato 11 inside comprises integrated circuit 15, by integrated circuit 15, the supply voltage stitch of mobile terminal SIM card, ground pin and high-voltage signal stitch is led to the outer wall of Kato 11.Concrete, each stitch of corresponding mobile terminal SIM card, integrated circuit 15 possesses corresponding metallic contact plate 151, and each metallic contact plate 151 is equipped with salient point 152, and after assembling, each salient point 152 contacts with corresponding stitch; And the salient point 152 that 3 contacts 12,13,14 of Kato outer wall are corresponding with supply voltage stitch, ground pin and high-voltage signal stitch is electrically connected.Kato 11 is made up of the first panel 16 and the second panel 17.Wherein, first panel 16 comprises the groove 161 matched with integrated circuit 15, and each metallic contact plate 151 position is hollow out 162, after assembling, integrated circuit 15 is embedded in described groove 161, and each metallic contact plate 151 is concordant with the first panel 16 through hollow out 162 position; Wherein, the second face 17 plate comprises the groove 171 matched with mobile terminal SIM card, and with salient point 152 circular hole 172 one to one, after assembling, salient point 152 contacts with the corresponding stitch of mobile terminal SIM card through circular hole 172.After assembling completes, mobile terminal SIM card is carried on Kato 11, and when inserting SIM cards of mobile phones screens, the corresponding stitch of mobile terminal SIM card is contacted with the shell fragment of SIM cards of mobile phones screens inside by salient point 152, metallic contact plate 151 successively, ensures the normal use of mobile communication function; The supply voltage stitch of mobile terminal SIM card, ground pin and high-voltage signal stitch are drawn to contact 12,13 and 14 by corresponding salient point 152 and vlsi circuitry, and then after mobile phone with the phone housing clamping that NFC functional module is housed, contact 12,13 contacts with the corresponding contacts of NFC functional module with 14, thus makes mobile phone have the structure of carrying out NFC communication based on SIM card safe mode (SE pattern).
