Abstract
The utility model discloses a mobile phone with multiple cards, which utilizes a switching function of the mobile phone to select the communication services provided by the different systems of multiple carriers. A battery back cover of the mobile phone is provided with a circuit board with multiple subscriber identification cards, and the circuit board is connected with an extension card through a row of lines. The extension card is an interface between the mobile phone and the circuit board, and is connected in parallel with each SIM card on the circuit board. The circuit is provided with a toggle switch. When the toggle switch points to one SIM circuit, the circuits of the mobile phone and the circuit of the corresponding communication system are connected (CLOSE) and conducted, therefore, the purpose of one mobile phone with multiple cards is realized.
Description
The utility model relates to the mobile phone of the many cards of a kind of unit.
General mobile phone all is Subscriber Identity Module (the SubscriberIdentification Module that utilizes system to provide, be called for short SIM card) as with the interface of base station communication, each phone only is furnished with a unique card, and can't be duplicated.Many consumers also want to have two or more communication systems simultaneously, but, as previously mentioned, each mobile phone can only have a number that system provided, just must buy two or above mobile phone if having the number of two or more different systems, for the consumer, not only increase expense, also feel inconvenience in the use because will carry two ones or above mobile phone.
Existing improvement is the mobile phone that can select to use simultaneously two kinds of different systems on single portion mobile phone; Its method is to increase by one group of former match system used SIM card of second system in addition on homemade battery, utilizes the designed Digital Logic IC of this device to select to use different communication systems with switching again, uses unit to enjoy two application targets that block to reach.But this kind improvement still has following shortcoming:
1, because product is to process on battery, and utilizes logic semiconductor IC that the function of use is provided, increased manufacturing cost.
2, the original space that utilizes of battery is little, thus can only provide the two cards of a machine to use, and be difficult to extend to again the wider of one-telephone multi-card.
3, software-driven in the IC is all passed through in the selection of two cards (system) and switching, and other softwares that this is easy and mobile phone is interior produce repulsion or inconsistent problems.
4, the user must remember the method switched, normally utilizes the button on the mobile phone to switch, otherwise can't use this function.
5, be installed on the battery owing to SIM card, and battery has certain life cycle, so after the battery damage can not be used, the functions of the two cards of a machine are forfeiture thereupon also.
The purpose of this utility model provides a kind of mobile phone with a plurality of SIM card, and it realizes the function of one-telephone multi-card by an external circuits plate.
The purpose of this utility model is achieved in that the battery back of the body at mobile phone covers installation one circuit board, the connector that has a plurality of fixed-line subscriber identification cards (abbreviation SIM card) on this circuit board makes conducting contact default on each piece SIM card and the circuit board be linked to be a shunt circuit; Have a flexible flat cable to connect an Extender Card on circuit board, this Extender Card is inserted in the former position that fixes SIM card of mobile phone, and the order circuit that makes mobile phone is Extender Card and connecting with the signal of circuit board thus; Another side in circuit board dress SIM card is equipped with a tumbler switch, and the circuit of this switch and aforementioned circuit plate connects into a loop, and when the arbitrary SIM card of switch connection loop, the circuit of mobile phone just is connected (CLOSE) conducting with the loop of this communication system.Above-mentioned switch is exposed at battery back of the body lid outside.
The utility model only covers processing at the back of the body of battery, and its assembling and manufacturing cost definitely are lower than the existing mobile phone of processing on battery.In a plurality of SIM card of battery back of the body lid mounted device, available space is very big, even space (because of it is plastic rubber shaping, so elasticity is very big) of can the demand of looking strengthening this back of the body lid to be loading more SIM card, and is not subject to the specification of former factory mobile phone fully.Utilize simple electronic loop to add that a tumbler switch does the switching of system and select, hardware cost is cheap, need be by the expensive IC control and the driving of software.Provide many cards to use with single mobile phone, utilize the simplest tumbler switch to make system and switch and select, the switching mode that the user needn't the hypermnesia complexity and make simplified control.Because a plurality of SIM card all are contained in the battery back of the body and cover, so even battery loss does not also influence the function of use of mobile phone.
Below in conjunction with accompanying drawing the utility model is further described.

Figure 13 is the end view of Figure 12.
Figure 14 is the rear view of Figure 12.
Figure 15 is the utility model schematic block circuit diagram.
As shown in Figure 1, the utility model comprises a mobile phone 10, battery 20 and the battery back of the body that combines with mobile phone 10 covers 30, and covering at this back of the body has the buckle element corresponding with mobile phone 10 on 30.
As shown in Figure 2, for the battery back of the body shown in Figure 1 covers 30 reverse side, this back of the body lid 30 has certain space and can pack into for a circuit board 31, this circuit board 31 is fixed on the back of the body by a plurality of fixed screws 35 and covers on 30, the connector 32 that a plurality of fixedly SIM card 40 are arranged on circuit board 31, each piece SIM card 40 by with circuit board 31 on default conducting contact be linked to be a shunt circuit as shown in figure 15; In addition, connect an Extender Card 34 with a flexible flat cable 33 on this circuit board 31, this Extender Card 34 inserts mobile phones 10 former positions (figure does not show) that fix SIM card, the order circuit that makes mobile phone 10 Extender Card 34 and the back of the body signal connection of cover circuit board 31 on 30 thus.
At circuit board 31 another side of SIM card 40 is housed, a tumbler switch 36 is housed, this switch 36 is exposed at the battery back of the body and covers 30 outsides with handled easily; This switch 36 connects into a loop with the circuit of aforementioned circuit plate 31, and as shown in figure 15, when switch 36 pointed to a SIM card loop, the circuit of mobile phone just was connected conducting with the loop of this communication system, reaches the application target of mobile phone one-telephone multi-card.
