Embodiment

As Fig. 2, Fig. 3 and shown in Figure 4, this mobile phone unit multiple card intercommunication device, be arranged between battery of mobile telephone 9 and the bonnet 11, it includes a printed circuit film 6, it is provided with three plastic-steel sim card slots 8 and corresponding SIM card, be respectively SIMa, SIMb and SIMc, and be provided with inserted sheet 1, it is a compound inserted sheet.This compound inserted sheet has and general identical profile and the size of SIM card, insert in the former draw-in groove 10 of mobile phone, but and its contact point and mobile phone draw-in groove contact be the state of relative conducting.

As shown in Figure 1, the combination of circuits of this mobile phone unit multiple card intercommunication device is made up of chip microprocessor 2, bidirectional analog electronic switch 3, capacitor 4 and diode 5.Described three groups of sim card slots all have the control point separately, and it is in parallel each other, utilize bidirectional analog electronic switch 3 as signal transmission to each other, specifically, the terminal 6 that connects I/O Data line on the inserted sheet 1 is two-way I/O data channel, it through bidirectional analog electronic switch 3 can with one of described sim card slot 8 UNICOM; The negative pole UNICOM of the input of chip microprocessor 2 and diode 5, its output and bidirectional analog electronic switch 3 UNICOMs; The positive pole of diode 5 links to each other with the first terminal of described inserted sheet 1, and its negative pole and capacitor 4 link; The ground wire of common UNICOM and the 4th terminal of described inserted sheet 1 link between chip microprocessor 2, bidirectional analog electronic switch 3 and the capacitor 4, and provide electric power loop by the first terminal and 4 of described inserted sheet 1, wherein make logic and memory signal is handled by chip microprocessor 2; Switch the I/O data of SIMa, SIMb and SIMc card by bidirectional analog electronic switch 3; Realize that by capacitor 4 and diode 5 mobile phones keep the power supply to integrated

circuit

2 and 3 when the of short duration outage, and control signal is imported mobile phone by inserted sheet 1.So behind the former sim card slot 10 of inserted sheet 1 insertion mobile phone, mobile phone can have many group (being three groups herein) identification numbers simultaneously, and can utilize the mobile phone operating key to select arbitrary group of SIM card as session services.

When external signal is borrowed inserted sheet 1 through chip microprocessor 2 and arbitrary group of SIM card of bidirectional analog electronic switch 3 gatings, SIM card can be responded the information that belongs under the same module and offer the user, and can select arbitrary group of other SIM card by mobile phone control button conditionally.

For an embodiment explanation, when the SIM card in user's desire use SIMa draw-in groove connects as conversation Jie, when opening the power supply of mobile phone for the first time, power supply signal can drive the contact of SIM card by inserted sheet 1, and produces the signal of a triggering chip microprocessor 2 immediately.If so far action is all errorless, then will be by the SIM card data in the bidirectional analog electronic switch 3 agreement use SIMa draw-in grooves.If will select for use the SIM card in SIMb or the SIMc draw-in groove to be situated between as conversing when connecing, then only need power-off with mobile phone in the above-mentioned use, start again within a certain period of time, chip microprocessor 2 just can select the SIM card of next round replacement to substitute.If just start shooting above the power-on time that capacitor 4 sets, the SIM card that then can reselect in the SIMa draw-in groove is first cis-position.

As shown in Figure 3, when using this device, inserted sheet 1 is inserted in the former sim card slot 10 of mobile phone, by the flexibility of printed circuit film 6, use the space mounting between battery 9 and the bonnet 11, and can not influence the fastening situation of mobile phone bonnet.

Above-mentioned explanation at the specifying of a kind of possible embodiments of the utility model, is not in order to limit protection range of the present utility model just.All equivalent embodiment or distortion that does not break away from the utility model design, for example: the shell that the model of mobile phone is arranged in pairs or groups, the equivalent embodiment that the configuration of perhaps different label mobile phones etc. change all should belong to protection range of the present utility model.
