Abstract
The utility model relates to an all-purpose ultra-thin mobile telephone double card which comprises a new style circuit board with double cards (FPC), a hardware elastic wafer, a card slot, an electronic component, etc. The concrete structure is that a double card circuit board is provided with two sets of hardware elastic wafers of the SIM card and two sets of SIM card slots. The card slot is two connected blocks, and the blocks are corresponding to the hardware elastic wafer and are pressed together with the circuit board. The blocks can be simultaneously provided with two SIM cards (such as a popular card and a mobile card). The on-line SIM card is welded with the electronic component, and the electronic component is inserted into a card base (slot) of the mobile telephone. The double-card realizes the double cards of one mobile telephone, and the interconversion of the two cards can be realized through the on-off of the mobile telephone.
Description
Technical field
The utility model relates to the SIM card of mobile phone, mainly be meant a kind of can general, ultrathin two cards in mobile phones.
Background technology
Mobile phone is a requisite communication tool during people live, and it brings great convenience for people's life, work, its furthered distance of people.But a large amount of telephone expenses make each user feel headache; And wear different SIM card (as UNICOM's card, popular card) and the other places cards of saving telephone expenses, and need frequently change card, make each user feel to bother very much; Carry two mobile phones in addition, make very inconvenience etc. of live and work.At this situation, someone designs the two cards of two IC rear-cover types and solves this problem, but because the two cards of two IC rear-cover types need be joined a bonnet in addition, make that attractive in appearance and the not general and SIM cards of mobile phones of fuselage thickening influence is can not using of 3V, this makes troubles just for the two promotion and application that block of a machine.
Summary of the invention
The purpose of this utility model be exactly provide in order to solve the problem that the two cards of current mobile phone one machine exist a kind of can general, ultrathin two cards in mobile phones.
The purpose of this utility model can reach by the following technical programs:
This two cards in mobile phones comprises Flexible Printed Circuit, integrated circuit, ultra-thin chip and electronic devices and components, five metals elastic contact blade, sim card slot.Concrete structure is that the wiring board of Flexible Printed Circuit one end is provided with two groups of five metals elastic contact blades, and corresponding five metals elastic contact blade is provided with two groups of sim card slots; The wiring board of the Flexible Printed Circuit other end is provided with company's machine SIM card, is provided with switch at company's machine SIM card face and touches piece and igniter module chip.
The utlity model has following advantage:
1. but the two cards of the machine of having realized and a kind of model different types of machines use.
2. adopt the ultrathin chip of import, use more stablely, quality is more reliable.
3. short message can not leaked receipts (SIM card of shutdown).
4. do not change the construction profile of existing mobile phone.
5. the five metals elastic contact blade adopts the whole shape design that connects, and makes that the SIM card contact is more stable.
6. be added with D1 in the novel circuit design, solving 3VSIM card mobile phone can use.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present utility model, represents that two SIM card and company's machine SIM card link together (1) two card Flexible Printed Circuit (FPC) among the figure, (2) (3) five metals elastic contact blade, (4) connect machine SIM card, (5) sim card slot, (6) SIM card contact.
Fig. 2 is an A-A cross section view among Fig. 1, the two card of expression horizontal section structure, therefrom the position relation between the soft electric line plate of two as can be seen cards, sim card slot, the SIM card five metals shell fragment three.
Fig. 3 is a B-B cross section view among Fig. 1, the two card of expression SIM longitudinal profile structure.
Fig. 4 is the stereogram of sim card slot among Fig. 1.
Fig. 5, Fig. 6 are circuit theory diagrams, and this circuit adopts the ultrathin IC of import twin lamella (switch module and igniter module) design, IC TSSOP Package.
Fig. 7 is PCB Lackage.
Embodiment
As shown in Figure 1, the utility model has comprised the dibit draw-in groove 5 that SIM-1 card and SIM-2 card can be installed, and the machine SIM-3 of the company card 4 that links to each other with the dibit draw-in groove by Flexible Printed Circuit (thickness is 0.18-0.22) 1.Two cards comprise SIM-1, SIM-2 card Flexible Printed Circuit 1, five metals elastic contact blade (adopt the manufacturing of bell copper product, thick be 0.10mm) 2,3, the contact 6 that is used for stablizing SIM-1, SIM-2 card.Draw-in groove 5 is two continuous square frames (shape of square frame inside casing is identical with used SIM card with size), and square frame is ultrathin design (thickness is 0.85mm), and corresponding five metals elastic contact blade 2,3 of square frame and wiring board 1 press together, and SIM card just is installed in the square frame.In order to compress SIM card, symmetry is given prominence to two compressing tablets on the interior edge of square frame, and this compressing tablet is pressed in above the SIM card.
When using this pair of card, (be welded with switch module and igniter module chip on this card, chip adopts the TSSOP encapsulation, and thickness is 0.85mm will to connect machine card SIM-3 card, even Flexible Printed Circuit lumps together integral thickness and is no more than 1.1mm, and being placed in the mobile phone deck (groove) has enough spaces.Between the input power vd D of igniter module and earth resistance R1, meet diode D1,5VSIM card and 3VSIM card mobile phone can both be used) insert in the sim card slot (seat) of mobile phone, SIM-1 card (as masses' card) and SIM-2 card (as moving card) that different range is used are installed in two draw-in grooves, because it is very thin that two draw-in grooves are done, even the software wiring board lumps together integral thickness and is no more than 1mm, so be placed on the interior existing space of battery flat of mobile phone, need not change the structure and the size of mobile phone.In the use, can realize conversion mutually between two cards by the open and close mobile phone.
