Abstract
The invention relates to a SIM card selecting unit used for mobile telephone with one or more SIM card slots at back or other suitable position of the mobile telephone to make each card can be connected with contact of card reader separately by switching component or be connected with card reader in the mobile telephone by function key at keyboard. Said unit is very convenient for use, it can avoid SIM lost and proceed to improve present mobile telephone as well as soldom increase cost.
Description
The present invention relates to a kind of mobile phone that is used for is SIM card choice device on the mobile phone.
Getting in touch between SIM card and the mobile phone is well-known, and at first it is used to connect with the interface circuit of mobile phone, and then makes the base station realize the accumulative total charging.In the prior art, only being provided with one on the mobile phone can promptly limit the user SIM card can only be installed at most on a mobile phone for the draw-in groove of user installation SIM card.Yet, in actual life, each relatively large life zone all is provided with a plurality of base stations that can be communicated with individual handset, and all there is its special function or purpose these base stations, so, have only the user of a mobile phone may hold a plurality of SIM card simultaneously, and when changing SIM card, all need first powered-down, then bonnet is opened, taken out program old and that put the so tired rope of new SIM card into again, simultaneously, because the external form of each SIM is basic identical, promptly be difficult on external form, with the naked eye tell the difference of above-mentioned SIM, so, when putting into new SIM card, be difficult to select and want the card put into, the process that also needs " examination ", and each trial assembly all will repeat once each above-mentioned process.
In sum, this kind mobile phone is that the SIM card on the mobile phone is very cumbersome in use, can bring many inconvenience to the user usually; In addition,, often carry it is lost, make its damage again easily owing to SIM card is very little usually.
Task of the present invention provides a kind of SIM card choice device that is used on the mobile phone, and it can make the card reader in selected SIM card and the mobile phone connect by the simple operations of finishing on the mobile phone easily.
For finishing above-mentioned task, SIM card choice device of the present invention comprises the SIM card draw-in groove that is arranged on mobile phone rear portion or other appropriate location, two SIM card can be installed in this draw-in groove at least, and each SIM card communicates with the contact of card reader by converting member discriminably, or by the function key on the keyboard it is communicated with card reader on the mobile phone.
Comprise at least two draw-in grooves that are used to install SIM card that are arranged on mobile phone rear portion or other appropriate location, and the SIM card in each draw-in groove communicates with the contact of card reader by converting member discriminably, or by the function key on the keyboard it is communicated with card reader on the mobile phone.
Described converting member can be made of change over switch that has the contact or contactless electronic switch.
Because the present invention can be put into a plurality of SIM card in the mobile phone simultaneously, as long as with hand switch or use specific keyboard operation program that selected SIM card and card reader are connected, so this device use is convenient especially, also can avoid SIM to lose effectively; Consider simultaneously and the supporting use problem of existing mobile phone, this device has just been made the logic function of simple change and an additional converting member or finger-board to the hull shape of mobile phone, so this device also can improve existing mobile phone, and increases how many costs hardly.
Below in conjunction with drawings and Examples the present invention is elaborated.
Accompanying drawing 1 is the surface structure schematic diagram of one embodiment of the invention;
Accompanying drawing 2 is circuit theory diagrams of an embodiment of described converting member;
Accompanying drawing 3 is surface structure schematic diagrames of another embodiment of the present invention.
Referring to Fig. 1 and Fig. 2, provide a kind of SIM card choice device of structure in the present embodiment, this device includes one and is arranged on preferably SIM card draw-in groove 1 and a converting member that is installed in mobile phone limit portion of appropriate location, mobile phone rear portion.Described converting member can be made of the guillotine type K switch that has six contacts, and contact K1 on this knife switch and the contact 2 on the card reader are joined, and contact K2 is controlled end, when move this switch with hand it is contacted with copper sheet on the SIM card, makes this SIM card enter user mode; When moving this switch, can make another SIM card enter user mode to other direction.In like manner, also a plurality of SIM card can be installed in the draw-in groove 1, can make its conducting or switching respectively in the same way.
Have, above-mentioned converting member also can be made of electronic switch again, promptly also above-mentioned two or more SIM card is switched in a manner described very squarely, because of this kind electronic switch prior art has many kinds, but all be that those of ordinary skill can be finished, so, no longer elaborate here.
Accompanying drawing 3 provides the surface structure schematic diagram of another SIM card choice device.As can be seen, this device is provided with two draw-in grooves 1 that are used to install SIM card at the rear portion of mobile phone from accompanying drawing, can be placed with a SIM card respectively in each draw-in groove 1, and knife switch K or electronic switch in the application drawing 1 can be finished task switching equally.
In addition, an intrinsic function is exactly to change logical block or program by substitution method in the interface circuit of mobile phone, so one or several function key that can set in advance in the logical key of merit on the keyboard group is to finish the operation sequence key that switches SIM card, the user can finish automatic switching function as required.
Claims (3)
1. be used for the SIM card choice device on the mobile phone, comprise the SIM card draw-in groove that is arranged on mobile phone rear portion or other appropriate location, it is characterized in that: two SIM card can be installed in this draw-in groove at least, and each SIM card communicates with the contact of card reader by converting member discriminably, or by the function key on the keyboard it is communicated with card reader on the mobile phone.
