Description
Technical field
The utility model belongs to information equipment accessory technical field, is related to a kind of TF card with SIM card function.
Background technology
TF card is T-Flash cards, is called Micro SD cards, i.e. miniature SD card, is a kind of general memory, is had special
Communication interface and dimensions, internal components mainly include master control driving chip and Nand flash storage chips, and
The contact point of resistance capacitance and circuit board, TF card is arranged in the circuit board edge edge of TF card.
Mobile phone mainly uses the SIM card (i.e. Nano SIM cards) of 4FF specifications, this nano SIM cards and traditional SIM card one
Sample, general only includes a chips, is connected and communicated with mobile phone by 5 metal contacts.Its maximum feature is exactly size
It is smaller, area be probably TF card area more than half of a bit.
A large amount of Android Android mobile phones currently on the market are all supported to be inserted into 2 or more SIM cards and TF card, insertion 2
SIM card can allow mobile phone to have the function of double-card dual-standby, be inserted into the memory capacity of TF then extendible mobile phones.To mobile phone user's
Work and life provide convenience.
Increasing with the screen of mobile phone, battery capacity constantly expands and the thickness of mobile phone the more does the more thin, in mobile phone
The device in portion also begins to continuous compressed dimension.So, a large amount of mobile phone also begins to space and the TF card slot of compression sim card slot
Space.Finally so that the sim card slot of quite a few mobile phone occupies the same space with TF card slot.Mobile phone vendor of the country at present
Most mobile phones of quotient are all to use this design.At this moment mobile phone user is encountered by a difficult alternative selection.
TF card is abandoned in mobile phone card slot, while being inserted into 2 SIM cards；It is inserted into TF card in mobile phone, but can be only inserted into a SIM
Card.
Utility model content
The purpose of the utility model is to provide a kind of TF cards with SIM card function, are improved to the structure of TF card,
The core component SIM card chip die particle of implantation SIM card inside TF card, makes the two functional unification, point after being put into mobile phone
With a slot.
The utility model is to realize above-mentioned purpose by technical solution below.
A kind of TF card with SIM card function, including master control driving chip, storage chip, circuit board and contact point are provided,
The storage chip and contact point that master control driving chip is set on circuit board and is electrically connected with master control driving chip, in circuit board
Above and it is additionally provided with SIM contact and SIM card chip, SIM contact and SIM card chip are electrically connected by the circuit of setting on circuit boards
It connects, SIM contact is located at the homonymy of circuit board with contact point, and SIM card chip, master control driving chip and storage chip are set to circuit
The other side of plate covers insulation protection shell by injection molding manner on circuit boards, and forms TF card external form.
In one embodiment of above-mentioned technical proposal, the SIM contact is five or six, the arrangement of SIM contact
It is consistent with the contact of SIM card, the signal of SIM contact connection mobile phone and SIM card chip when use.
Description of the drawings
Fig. 1 is the front view of the Kato with double SIM card slot in embodiment.
Fig. 2 is the single side view of the TF card with SIM card function in embodiment.
Fig. 3 is the side structure view for the TF card with SIM card function that embodiment is listened.
Specific implementation mode
The technical solution of the utility model is further described in detail with specific embodiment below in conjunction with attached drawing.
It is a kind of Kato with double SIM card slot shown in referring to Fig.1, SIM1 slots therein can only place a Nano
SIM cards can place a Nano SIM card or a TF card, because of the position of the position of TF card and SIM card in SIM2 slots
Set coincidence, this Kato cannot in a mobile phone simultaneously support TF card and double-card dual-standby, the slot can only both select one,
A Nano SIM card or a TF card can not be used simultaneously.
With reference to shown in Fig. 2, Fig. 3, the present embodiment is a kind of TF card with SIM card function, including master control driving chip 2, is deposited
Chip 3, circuit board 1, contact point 4, SIM contact 5 and SIM card chip 6 are stored up, which has storage section and SIM function parts
Point.
Wherein storage section includes master control driving chip, storage chip and contact point, is all respectively set on circuit boards,
Master control driving chip is electrically connected storage chip and contact point.SIM funtion parts include SIM contact and SIM card chip, are all divided
Be not arranged on circuit boards, SIM contact and SIM card chip are electrically connected by the circuit for being arranged on circuit boards, SIM contact with connect
Contact is located at the homonymy of circuit board, and SIM card chip, master control driving chip and storage chip are set to the other side of circuit board,
Insulation protection shell 7 is covered by injection molding manner on circuit board, and forms TF card external form.
SIM contact can be five or six, and the arrangement of SIM contact is consistent with the contact of SIM card, and SIM is touched when use
The signal of point connection mobile phone and SIM card chip.
One example of making of the TF card of the present embodiment is, by the TF card circuit of SIM funtion parts circuit and storage section
Design is on the same circuit board, then by connecting upper SIM card core using binding technique or paster technique on circuit boards
Piece and Nand Flash chips and Nand Flash driving chips；
5 or 6 SIM contacts are designed on one side on the outside of TF card circuit board, their position corresponds to mobile phone
The position of Nano SIM cards contact, size also at least can guarantee that the contact reed of mobile phone card slot reliably connects.Outside this
A little SIM contacts will guide to the other side (being known as inside) of circuit board by circuit connecting wire, and SIM card chip mount is in circuit board
Inside is simultaneously connect with these circuit connecting wires by binding technique or paster technique；
When all electronic devices all patch or binding after, by the appearance and ruler that are molded and cut into usual TF
It is very little.After completing detection, a kind of TF card with SIM card function has been performed from electronic hardware angle.It only need to be under SIM card chip
Suitable program and data are carried, just have complete function.
Upper embodiment is the preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, for the common skill in this field
For art personnel, any obvious change done on the basis of without departing substantially from the technology of the present invention principle belongs to this hair
The protection domain of bright design and appended claims.
