Description
Technical field
The invention belongs to mobile terminal device technical field, and in particular to SIM card and TF the cards connection of a kind of mobile terminal
Device.
Background technology
Increasingly go deep into the live and work of people now with consumable electronic products such as mobile phone, digital camera and PDA,
The use of the storage card product such as SIM card, SD card and TF card is also more and more extensive.And attachment device be then realize these storage cards with
Mobile terminal carries out the electronic product of the most convenient of data exchange, due to its cheap price, the performance suitable with USB flash disk and very
High versatility, to communication of mobile terminal card connecting device research and development be still hot spot direction in presently relevant industry it
One.
Originating from extensive electronic bits of data processing is solved the problems, such as, its earliest extensive use is exactly to remember for the application of smart card
Card is recalled, in the use of phonecard.The application range of smart card includes meeting SIM cards and PIM cards of GSM specifications etc..With
Exemplified by SIM card (Subscriber Identity Module), i.e. subscriber identification module, it is one and meets GSM specification " intelligence
It can block ".SIM card may be inserted into any mobile phone for meeting GSM specifications, realize telephone number with the not random work(of card
Can, and call rate is then included in the bill of card user automatically, it is unrelated with mobile phone itself.
At present, China's distribution SIM card has the company such as China Unicom and China Mobile.For traditional SIM card, it is deposited
Capacity is stored up for 8K, 16K, 32K, 64K etc., and in Chinese international communication exhibition, China Mobile has put on display memory capacity and reached 4G
SIM card above, and point out that the SIM card in future will have stronger disposal ability, the storage volume of bigger, and the biography of higher
Defeated speed.In addition, at present people the frequency of use of large capacity mobile memory medium is increasingly increased, commonly using to have：TF
Card, SD card, USB flash disk and mobile hard disk etc..Wherein, TF card has the advantages that compact, cheap and memory capacity are big, it is not
The application prospect come is boundless.
" attachment device " as the term suggests being a kind of equipment for reading data, but it can not merely support that the reading of data is same
Sample also supports the write-in of data.The mentality of designing at its initial stage is primarily to making up the defects of data of digital camera exports and producing
's.Since early stage USB interface is not popularized, the delivery outlet of digital camera is all that the serial ports of same computer connects, due to string
The data transmission bauds of mouth is very low, if in these data copies to hard disk, that will spend the substantial amounts of stand-by period, because
This, card reader class attachment device is just come into being, but it has been no longer limited to the use of digital camera at present, but is expanded
More fields of mobile phone, mobile terminal etc. are opened up.For the ease of using, present card reader is typically all the production of All-in-One
Product, it can be written and read the storage card of a variety of different data formats.
Common SIM card holder on existing mobile phone, TF (also known as T-Flash cards, full name：Trans-Flash, also known as：
Micro SD, are researched and developed jointly by Motorola with SANDISK, are released in 2004) deck is all single, so hand in practice
Just need two decks to be integrated into one piece of small PCB circuit board to design in the design of machine.Although this mode can be
Mainboard saves many cloth member spaces, but also increases the design cost of whole mobile phone at the same time, because this design method needs
Input manpower goes to design, and then also to go to process by paster technique.
With the continuous development of communication tool, structure, pattern and the performance of mobile phone are more aobvious also increasingly frequent, people couple
The requirement of mobile phone is also higher and higher.The application of general mobile phone, mostly enters SIM (subscriber identification module) card insertion set by mobile phone
Card slot in, and complete reinstate program after, you can received, called using mobile phone.In existing mobile phone card seat except
It is provided with outside TF card, is also equipped with two Micro-SIM cards, when two Micro-SIM cards and TF card are inserted in mobile phone card seat
Afterwards, shell is easily loosened so as to be jacked up, and eventually results in card read failed, use is extremely inconvenient.
