Description

A kind of mobile phone

The utility model relates to a kind of mobile phone.

Prior mobile phone is provided with a SIM card (user identity assembly) deck, and synchronization can only be adorned a SIM card in the mobile phone, and promptly No. one one location of a card is perhaps named a card one service.Along with the development of telecommunications industry, various places have released one after another, and this province leads to or this locality of cities and counties lead to SIM card.The suitable application region of different SIM card, charge method and toll rate are all different, and this has just satisfied the different needs of different user.But also there is sizable a group of people often to go on business or travel, perhaps between several ground of fixed point, has long-term business concurrently, need contact frequent between several ground.In this case, everybody just thinks to hold simultaneously Global Link and local logical, and perhaps this province is logical and local logical, and perhaps this province of several provinces is logical, perhaps the logical SIM card in this locality of several cities and counties etc.So, just need everywhere in mobile phone, replace with corresponding SIM card, change SIM card so continually, both bothered, cause losing or damaging of SIM card again easily, bring inconvenience to the user.

The purpose of this utility model is to provide a kind of mobile phone, in this phone two or more SIM card can be installed simultaneously, make the user can switch selectively as required connection wherein one stick into the row answer or call.

In order to achieve the above object, the utility model has adopted a kind of mobile phone, this mobile phone is that the position beyond an original SIM card deck is provided with one or more SIM card deck again, is provided with the SIM card conversion controling switch between the line of the inner corresponding line of the corresponding contact of above-mentioned each SIM card deck and mobile phone.

The positive supply contact of described each SIM card deck and the positive power line V of mobile phone inside _CCBetween be provided with the SIM card conversion controling switch.

Described SIM card conversion controling switch is mechanical type change over switch K, and the public contact of change over switch K meets the positive power line V of mobile phone inside _CC, the branch contact of change over switch K connects the corresponding power end contact of each SIM card deck respectively.

Described SIM card conversion controling switch can be the electronic type change over switch, and this electronic type change over switch can be by four button K that all have a pair of normally opened contact ₁, K ₂, K ₃, K ₄Constitute with four road rest-set flip-flops, the output of four road rest-set flip-flops links to each other with the corresponding power end contact of four SIM card decks respectively, and four road rest-set flip-flops are respectively 2 input NAND gate IC of cross-couplings connection in twos ₁, IC ₂, IC ₃, IC ₄, IC ₅, IC ₆, IC ₇, IC ₈, above-mentioned each button K ₁, K ₂, K ₃, K ₄An end link to each other with ground wire respectively, the other end respectively with the power line V of mobile phone _CCLink to each other the 4 input NOR gate IC that another input of four road rest-set flip-flops is corresponding with four respectively with one of them input correspondence of four road rest-set flip-flops ₉, IC ₁₀, IC ₁₁, IC ₁₂Output link to each other, these four 4 input NOR gate all have an input end grounding, its excess-three input of each 4 input NOR gate links to each other with the output of other three road rest-set flip-flops respectively.

Owing to be provided with two or more decks simultaneously in the mobile phone of the present utility model, in the mobile phone two or more SIM card can be installed simultaneously, the user can select a SIM card to answer or call in some periods as required, this has not only made things convenient for the user, satisfy user's different needs, saved many costs of the phone call to the user again.

The utility model is further explained and explanation below in conjunction with accompanying drawing:

Fig. 1 is circuit catenation principle figure of the present utility model;

Fig. 2 is the catenation principle figure of mechanical type SIM card change over switch;

Fig. 3 is the catenation principle figure of electronic type SIM card change over switch.

The structure of SIM card deck of the present utility model and common mobile phone do not have any difference, near original SIM card deck or suitable position other SIM card deck can be set, 3-4 deck just can satisfy the demand (more deck can certainly be set) is set in next mobile phone of ordinary circumstance.Supposition is provided with 4 SIM card decks in the present embodiment, is separately installed with the Global Link SIM card of two numbers, the logical SIM card in the cities and counties of a logical SIM card of this province of a number and a number.Owing to do not change on each deck structure, herein just no longer particularly accompanying drawing represented.The user can be switched selection as required by stirring the mechanical type change over switch or pressing the electronic type change over switch between four SIM card, use the jack per station of different rights to converse.

Among Fig. 1, pin 1 to the pin 6 of four SIM card decks (SIM1, SIM2, SIM3, SIM4) is represented the power end V of each deck respectively _CC, reset terminal RST, time control end CLK,, programming Control end V _PpAnd Data Control end DAT.The operate as normal of each SIM card all need power up, so be power end V to each card to the selection mode of SIM card eaily _CCControl.Therefore, adopt among this figure earlier the pin 2 of each SIM card deck to the pin 6 corresponding short circuits respectively with corresponding reset line RST, clock control line CLK, ground wire, the programming Control line V of mobile phone internal wiring _Pp, Data Control line DAT links to each other, the power end V of four SIM card decks then _CC1-V _CC4Equal power line V by a SIM card conversion controling switch KK and mobile phone inside _CCLink to each other.Reach the switching SIM card by Switching power.Need to prove; carry out switching controls as power end to each SIM card; to pin 3, pin 4 or the pin 5 of each SIM card respectively or the effect of carrying out switching controls simultaneously be the same, also should belong to the equivalent variations of the technical scheme of the utility model protection, give unnecessary details no longer one by one herein.

Among Fig. 2, the power end V of four SIM card deck SIM1, SIM2, SIM3, SIM4 _CC1, V _CC2, V _CC3, V _CC4Four branch contacts that connect mechanical type change over switch K respectively, the public contact of change over switch K and the power line V of mobile phone internal wiring _CCLink to each other.

Among Fig. 3, the voltage end V of four SIM card deck SIM1, SIM2, SIM3, SIM4 _CC1, V _CC2, V _CC3, V _CC4Power supply V by an electronic type change over switch and mobile phone internal wiring _CCLink to each other.Among the figure, four button K ₁, K ₂, K ₃, K ₄The formation that links to each other with an input of four road rest-set flip-flops switching circuit.Every road trigger all is to constitute with cross-linked two 2 input non-conjunctions.No. four triggers are respectively by NAND gate IC ₁And IC ₂, IC ₃And IC ₄, IC ₅And IC ₆, IC ₇And IC ₈Constitute.Four outputs of No. four triggers respectively with the power end V of four SIM card decks _CC1, V _CC2, V _CC3, V _CC4Link to each other.Above-mentioned four buttons all have a pair of normally opened contact, the correspondence of rest-set flip-flop input termination positive supply V during the button free state _CC, should the correspondence input end grounding when pressing the button.In order to guarantee that whenever by next button, corresponding one road rest-set flip-flop is output as " 1 ", and remaining three road rest-set flip-flops output is " 0 ", 4 inputs " NOR gate " IC that another input of each road rest-set flip-flop is corresponding with four respectively ₉, IC ₁₀, IC ₁₁, IC ₁₂Output link to each other, the equal ground connection of one of them input of each 4 input " NOR gate ", its excess-three input links to each other with the output of other three rest-set flip-flops respectively.
