Description

The integrated circuit (IC) chip expanding device

Technical field

The utility model relates to integrated circuit (IC) chip, relates in particular to the expanding device of integrating at the multiple ic chip chamber.

Background technology

Subscriber identify module card (Subscriber Identity Module Card, SIM Card) is a kind of smart card (Smart Card) that is applied to device for mobile communication, and its instrument as stored user status identification data, telephone number, news in brief etc. uses.Because required most data when subscriber identify module card (SIM card) is stored the user and carries out communication, and standard criterionization, therefore, the user only need move this SIM card and promptly can be applicable on the different device for mobile communication.Except above-mentioned data, SIM card has still stored other data, comprise as international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), interim identification code (Temporary Mobile Subscriber Identity, TMSI), confirm golden key (Ki), PIN (Personal Identification Number) (Personal Identification Number, PIN), SIM card unlocking pin (PIN un-block key, PUK), IC-card identification code (IntegratedCircuit Card ID, ICC-ID) and SIM card application tool group (SIM Tool Kit, STK) etc.

General SIM card has stored identification data such as the IMSI of the prior institute of operation dealer burning and Ki when dispatching from the factory, that is to say that the employed SIM card of user can't be used other operation dealer's mobile telecommunication service.For the user who strides operation industry merchant, must carry multiple SIM card or many device for mobile communication, this is inconvenience quite.In addition, the download of STK also is subject to the operation dealer, and the user can't download the STK that other operator provides, and causes the obstruct in mobile communication market, has limited the development of mobile telecommunication service.And the storage area of SIM card is quite limited, and does not have the possibility of expansion, and the user is often because the problem of capacity is forced to delete important phone or news in brief.The problems referred to above for the user who relies on device for mobile communication day by day, exist sizable inconvenience really, and have limited the possibility of mobile communcations system development.

Known announces No. 496621, No. 558040 and certificate M283446 patent case as TaiWan, China, has disclosed multiple mobile phone two-card expanding device.Mainly two SIM card are electrically connected mutually by a film circuit board, again by a control chip card that couples with this film circuit board, perhaps with after two SIM card doublings on the film circuit board, plug on the SIM card holder in the mobile phone, make this mobile phone be possessed the function of double SIM card and obtain different mobile communication dealers' service.Yet compared to traditional single SIM card, above-mentioned technology has increased considerable volume beyond doubt.The holder of general mobile phone installing SIM card is to be positioned at the space, back, and this space, back major part is that battery is occupied, does not have unnecessary space can set up other device.Desire is used above-mentioned expanding device, certainly will will arrange in pairs or groups to have the device for mobile communication in space, enough backs, and this has limited the usable range of this expanding device.If force this expanding device of installing, contact between the damage, battery that probably can cause battery fastener tenon and mobile phone bad, even the problems such as destruction of handset structure.

See also other SIM card expanding device again, announce shown in No. 585374, certificate M275641 number, M298847 patent case as TaiWan, China, the apparent size of those SIM card expanding devices is identical with general SIM card, mainly comprises two draw-in grooves, and the circuit board that is positioned at the draw-in groove bottom.For avoiding increasing too much volume, SIM card must be passed through the means of cutting out, and inserts in this draw-in groove after chip is taken off, and can link mutually by circuit board between the chip.At last, at the outside cover sliding device that uses of this expanding device.The both sides of this slip lid have the slide rail that one bending is shaped, and this slide rail can slip in this slip lid for this expanding device, are installed in two chips in this expanding device with protection.In the technology that discloses before, this expanding device is installed in the holder of script SIM card, does not need the extra installing space that increases, and also can not cause the problem of battery installing.Yet, be positioned at the protruding rectangular structure of this slide rail bottom side, make integral thickness increase, expanding device can't be installed smoothly in this holder, even cause the difference of pressurized power and destroy chip.In addition, the rectangular structure of this projection is also tied with the mutual hook of other member easily, and causes the damage of slide rail.

The utility model content

Fundamental purpose of the present utility model is to expand the function of single SIM card, and makes it be widely used in various device for mobile communication.For reaching above-mentioned purpose, the utility model provides a kind of integrated circuit (IC) chip expanding device, includes supporting body and lid.The face of establishing that connects that this supporting body includes loading end and is positioned at these supporting body outer peripheral edges is concaved with at least one for the installing groove that integrated circuit (IC) chip is provided with on this loading end, this connects and then is provided with at least one first fixed part on the face of establishing.This lid includes to be covered in the upper cover part on this loading end and to be positioned at this and meets the portion of establishing that connects that establishes the face relative position; this connects has at least one and second fixed part of the corresponding buckle of this first fixed part in the portion of establishing, make this lid be fixed in this supporting body top to protect this integrated circuit (IC) chip.

Wherein, this supporting body comprises the framework that forms this installing groove, and the film circuit board with circuit layout.The electric terminal that has this integrated circuit (IC) chip of electrically connect on this film circuit board.In addition, have on this film circuit board and utilize this circuit layout to be coupled to the control chip of this integrated circuit (IC) chip; Perhaps this control chip directly is arranged in this framework, and is electrically connected at this film circuit board.This control chip can built-inly have wireless communication module or internal memory.This upper cover part and this loading end have first perforation and second perforation separately at relative position.Be inserted in the SIM card holder for making this lid have the flexible the utility model that makes things convenient for, have at least one indent segmental arc in the portion of establishing that connects of this lid.

By this, the utility model integrated circuit (IC) chip expanding device there is no the structure that projection occurs on surface structure, be able to the smooth-going device for mobile communication that is installed in and be used for installing in the holder of SIM card.Can be because of structural obstruction, and cause difficulty in the installing.Therefore, be applied on the various device for mobile communication, to reach the function that SIM card expands.
