Embodiment
The storage card that the present invention one integrates the USB interface is to be SD storage card or MS storage card, at first, describes the structure of this SD storage card earlier in detail.The structural representation of the SD storage card 10 at the present invention one integration USB interface as shown in Figure 1, it is to comprise a body 12, be provided with a SD memory chip 14 in body 12, this SD memory chip 14 is connected with plural conductive bar 16, and bus 16 is exposed by an end surfaces of body 12.Wherein, the structure of SD memory chip 14 as shown in Figure 2, SD memory chip 14 is to be provided with a storer 18, but it typically is a flash memory or electronic type clear program ROM (read-only memory) (EEPROM), at storer 18 built-in SD control interfaces 20 and USB control interface 22, other has a controller 24 to be connected with this storer 18, and have an interface control program 26 in the controller 24, control interface 20 or be USB control interface 22 but make controller 24 nationalitys select to carry out SD by this interface control program 26.
In addition, the present invention one integrate the USB interface the MS storage card spatial structure equally also as shown in Figure 1, the structure of its MS memory chip is similar to Fig. 2, not existing together, only to be to press down control interface 20 be by MS control interface replacement.
The spatial structure of breakout box of the present invention as shown in Figure 3, its partial sectional view because SD storage card 10 is identical with the structure of the breakout box of MS storage card, will illustrate the structure of this breakout box with SD storage card 10 below therefore as shown in Figure 4.The breakout box 30 of one SD storage card 10 is to comprise a grafting pedestal 32, so that this SD storage card 10 of pegging graft to be provided, in grafting pedestal 32, be provided with bus 16 corresponding plural conductive pins 34 with SD storage card 10 surfaces, so that forming with SD storage card 10, grafting pedestal 32 is electrically connected, front end at grafting pedestal 32 is provided with a USB joint 36, and the conductive connecting pin 34 in this USB joint 36 and the grafting pedestal 32 utilizes conductor wire to form to be electrically connected.
When the no grafting breakout box 30 of SD storage card 10, controller 24 in the SD memory chip 14 utilizes its interface control program 26 to select SD control interface 20 to carry out automatically, after making SD storage card 10 be plugged to the SD card reader, the SD storage card 10 that can be a standard operates smoothly.
When in SD storage card 10 will be plugged on a USB slot, using, can be as shown in Figure 4, bus 16 ends of SD storage card 10 are inserted in the grafting pedestal 32 of breakout box 30, form as shown in Figure 5, the bus 16 on SD storage card 10 surfaces is contacted to form electrical connection with grafting pedestal 32 interior corresponding conductive connecting pins 34; USB joint 36 with breakout box 30 inserts in the USB slot again, at this moment, the USB slot is via the bus 16 whole formation conducting states of the conductor wire in the USB joint through conductive connecting pin in the grafting pedestal 32 34 and SD memory chip 14, make the controllers 24 in the SD memory chip 14 utilize its interface control program 26 to start USB control interfaces, can operate smoothly after being connected to the USB slot for SD storage card 10.
In like manner, the MS storage card does not have grafting breakout box 30 or grafting breakout box 30 is arranged and when desiring to use, its interactively is identical with above-mentioned principle in a USB slot, and not existing together only be that SD control interface 20 becomes is MS control interface, so repeat no more.
Therefore, storage card of the present invention is the SD or the MS storage card of standard at ordinary times, when pegging graft breakout box of the present invention, the wafer of storage card inside just starts USB control interface, use in the USB slot and can insert immediately, so, the present invention utilizes SD storage card or the MS storage card that has USB and SD control interface/MS control interface in a breakout box and, making the SD/MS storage card in can being plugged on SD card reader and MS card reader and using, also can utilize this breakout box to enlarge the application of SD/MS storage card, make it to insert the computer that generally is provided with the USB slot, use more universalness and effect more easily to reach.
Above embodiment only is used for illustrating the present invention, and non-limiting the present invention, protection scope of the present invention is as the criterion with claims.
