Description
Technical field
The present invention relates to a kind of memory card capable of automatic compensating interface specification, particularly relate to and a kind ofly expand a communication interface beyond the standard interface in addition, and the specification of this communication interface and read-write equipment size for connection is had the storage card of automatic compensation function.
Background technology
At present known on the market mini memory card kind is extremely many, for example SD, CF, SM, MMC, xD, MS or the like, and the demand that these mini memory cards are common and characteristic are that volume dwindles as far as possible, only capacity expansion as far as possible can reach more than the 1GB aspect the capacity.Although storage card has tangible breakthrough on capacity, but each storage card all can only be connected with read-write equipments such as computer, electronic products according to the specific criteria agreement of itself in principle, when different storage card desires connects computer, the card reader that must see through same convention begins for it, and can't directly connect computer.
For solving foregoing problems, industry is to attempt exploitation to have two kinds of storage cards that connect interface, and wherein an interface can meet the conversion module of this interface appearance forrns merely to connect computer through one.The aforementioned practice has really efficiently solved the problem that storage card can't directly link computer.But a kind of more advanced idea is: if storage card itself can directly be plugged on the interface port of computer, convenience on it uses will further significantly be promoted, in other words, being directly to increase another one interface port at storage card, can directly peg graft on computers the interface connector in this interface port.But realize before this idea, must consider the specification and present computer interface standard difference separately commonly used of storage card itself earlier:
The most general interface connector should belong to USB (universal serial bus) on the computer at present, put USB as on storage card, building, promptly can directly be connected with most computer, but what must consider is specification difference between storage card itself and the USB interface port, to avoid but influencing the normal use of the original interface of storage card for yielding to the specification of this extending interface.See also shown in Figure 180ly, disclosing has a USB interface joint 80, and these USB interface joint 80 front ends are the metal skeleton frame 81 of a rectangle, skeleton frame 81 inner bottom surfaces are provided with an insulcrete 82, insulcrete 82 is provided with four groups of terminals 820, and it is respectively data line D+, D-, power lead VCC, GND.
As distinguish the form of USB interface with male and female, aforementioned USB interface joint 80 is male joints, the USB interface connector 90 (as shown in figure 19) that generally is located on the computer then is a female joint form, this USB interface connector 90 is that the upper end in a rectangular metal shell block 91 is provided with an insulcrete 92, has a space between insulcrete 92 end faces and shell block 91 inner top surfaces, insulcrete 92 bottom surfaces then are provided with four winding point shell fragments 920, it corresponds respectively to four groups of terminals 820 on the USB interface joint 80, aforementioned again shell block 91 top bottoms are arranged with four groups to shell block 91 inner outstanding Location resilient pieces 910, in order to support the fixing USB interface joint 80 that inserts shell block 91 of pulling.
See also shown in Figure 20, announcement has USB interface joint 80 to insert USB interface connector state after 90s, the skeleton frame 81 of USB interface joint 80 is inserted in the shell block 91 of USB interface connector 90 appositely, 82 of insulcretes in the skeleton frame 81 are inserted between the inner bottom surface and insulcrete 92 of shell block 91 relatively, and 920 correspondences of the contact shell fragment on the insulcrete 92 electrically contact the terminal 820 on the insulcrete 82 and constitute electrical connection.
Can understand by above-mentioned explanation, with regard to USB interface joint 80, the effect of its skeleton frame 81 is to be the location, real constitute electrical connection person then be insulcrete 82 and on terminal 820, based on considering of size, want on storage card, to integrate a USB joint, can only select to establish terminal 820 with the actual insulcrete 82 that is electrically connected purpose of reaching.Even only only select the actual structure that is electrically connected purpose of reaching, its specification still is not inconsistent with existing storage card, as shown in figure 19, the space that the insulcrete of shell block 91 inner bottom surfaces of this USB interface connector 90 and its top is 92, it promptly is space for insulcrete 82 insertions of USB interface joint 80, the height in this space is slightly larger than the thickness of insulcrete 82, is beneficial to insert, and only is provided with Location resilient piece 910 in addition and is pushed against; Modern if insulcrete 82 is incorporated on the storage card, its thickness still must cooperate with the space of 92 of the insulcretes of shell block 91 inner bottom surfaces and its top, as the thickness deficiency, may become flexible and causes electrical connection bad.Since but be to be incorporated on the storage card, just can not unilaterally satisfy the specification demand of USB interface itself, with the SD card is example, and its width/length/thickness is 24mm, 32mm, 2.1mm in regular turn, and the space of 92 of the insulcretes of shell block 91 inner bottom surfaces of USB interface connector 90 and its top is about 2.5mm.In other words, when the USB interface port of a power taking coupling part is integrated in a SD card and meet the specification of this SD card (thickness is 2.1mm), with regard to thickness, it is not enough to firmly be seated in USB interface connector 90, and does not obviously meet the USB interface standard.
For compensation USB joint is incorporated into the specification difference that is caused behind the storage card, the inventor had before once proposed No. 094109961 " storage card of tool interface standard compensation function and sheath thereof " patent of invention case of TaiWan, China patented claim, so that concrete solution to be provided, the aforementioned patent case mainly provides a sheath and takes in therebetween for a storage card, wherein this storage card at one end is provided with one first interface Port, is provided with one second interface port at relative end in addition; Sheath comprises a shroud and upper shield again, this shroud can be therebetween ccontaining for storage card, only make the second interface Port of storage card be exposed to outside the shroud, the cover edge that covers in its opening stretches out and is formed with a compensate gasket again, this compensate gasket right position is in the bottom of the storage card second interface Port, so as to compensating the thickness of the second interface Port, make it to meet the dimensions of set corresponding interface connector on the read-write equipment.
Can understand by aforementioned patent case content, what the so-called second interface Port referred to is exactly the USB joint, and utilize compensate gasket on the sheath to compensate the thickness of this second interface Port, the basic specification that promptly meets a standard USB joint, thus can mate fully with the interface connector of corresponding agreement on the read-write equipment and obtain firm engagement relationship; Because simple structure and convenient and practical is to get permission patent (TaiWan, China patent for invention I249884 number).
Only the indemnifying measure of aforementioned patent case still must rely on the outside sheathed sheath beginning of a storage card and can reach, though structure is light merely, indemnifying measure if can be integrated in storage card inside, for the user with convenient more.
This shows that the storage card of above-mentioned existing compensation interface specification obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of memory card capable of automatic compensating interface specification of new structure, just becoming the current industry utmost point needs improved target.
Because the defective that the storage card of above-mentioned existing compensation interface specification exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of memory card capable of automatic compensating interface specification of new structure, can improve the storage card of general existing compensation interface specification, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through after studying sample and improvement repeatedly.
