Description
Technical field
The present invention proposes a kind of switching element, conversion equipment and conversion method, particularly about switching element, conversion equipment and the conversion method of mechanism to support various memory cells or electronic installation by replaceable switching element.
Background technology
Along with scientific-technical progress, multimedia player (as MP3 Player, MP4 Player and PMP), personal digital assistant (Personal Digital Assistant, PDA), the development of electronic installations such as digital still camera, numerical digit video camera or computer and application are quite polynary, and the memory card of can arrange in pairs or groups external or interpolation, hard disc or memory cells such as dish with oneself, the capacity or the function that store data with increase.At present personal digital assistant, MP3 Player or PMP product on the market provides universal serial bus interface (USB) and one to two kind of memory card slot mostly, digital still camera then with provide a kind of memory card slot and universal serial bus interface or IEEE-1394 serial port both one of product comparatively common.Owing to memory card is considered according to the commerce of each manufacturer and manufacturing technology evolution has plurality of specifications, and electronic installation can't be supported multiple memory card usually simultaneously, or in to have its price of device of supporting various memory card functions comparatively expensive, therefore, derive products such as adapter and card reader, with transmission interface that solves electronic installation or the problem that slot can't be supported various memory card specifications.
See also Fig. 1 and Fig. 2, it is respectively the block schematic diagram and the schematic appearance of the disclosed a kind of card reader of prior art, this card reader 1 includes one first Plug Division 11, one second Plug Division 12, one switches unit 13 and connects interface 14, wherein, first Plug Division 11 and second Plug Division 12 can be for different types of memory cards of pegging graft, switch unit 13 respectively with first Plug Division 11, second Plug Division 12 and connection interface 14 connect, be used to make connection interface 14 and first Plug Division 11 or 12 conductings of second Plug Division, connect 14 of interfaces and can carry out the data transmission with first Plug Division 11 of 13 conductings of switch unit or the memory card in second Plug Division 12, by above-mentioned, if electronic installation possesses and the corresponding Port of connection interface 14, the memory card of then corresponding first Plug Division 11 or second Plug Division 12 can provide this electronic installation access data via card reader.
See also Fig. 3 and Fig. 4, it is respectively the explosive view and the schematic appearance of the disclosed a kind of adapter of prior art, this adapter 3 includes shell 31, circuit substrate 32 and conversion terminal 33, wherein, shell 31 has hollow-out parts 312 and hollow structure, and hollow structure is offered a slot 311 and ccontaining this circuit substrate 32.The one side of circuit substrate 32 is provided with a plurality of golden fingers of corresponding hollow-out parts 312, and it is exposed by hollow-out parts 312, and another side is provided with a plurality of electrical pins 321.One end of conversion terminal 33 is a weld part 331, can weld for the electrical pin 321 with circuit substrate 32, and the other end of conversion terminal 33 is a junction 332 then, is used to connect the electrical contact in the slot 311.By above-mentioned, when electronic installation has the transmission interface of corresponding those golden fingers, memory card is inserted slot 311, memory card can provide electronic installation access data by conversion terminal 33 and circuit substrate 32.
Above-mentioned card reader major function only limits to make electronic installation to can read the data of various memory cards, because the transmission interface of electronic installation is not quite similar, therefore card reader also can't connect various electronic installations, or card reader can be set up a plurality of connection interfaces to increase its range of application, yet, setting up connection interface and Plug Division not only can influence the manufacturing cost of card reader, and the volume potential of card reader must increase relatively, causes the inconvenience on carrying and taking in.Above-mentioned adapter mainly can increase the range of application of memory card, because the manufacturing technology of memory card is maked rapid progress, therefore the specification of memory card is more and more various, if the memory card slot that personal digital assistant, multimedia player and digital still camera provided that the consumer holds is different, then need buy multiple memory card or use adapter, yet, the memory card switching that adapter only limits to fixing specification is the interface of another kind of specification, for the consumer who holds multiple electronic installation, its function has not been applied demand.
