Description
Technical field
The utility model relates to a kind of adapter structure.
Background technology
From digital camera, PDA, 3C digital products such as MP3 walkman come into vogue, also driven the flourish of flash memory, derive the big or small pattern of various differences, the memory card of specification, with the total SM (Smart Media) of present modal memory card specification, xD-Picture Card, CF (Compact Flash), MD (Micro Drive), MS (Memory Stick) and SD (Secure Digital), MMC (MultiMedia Card) etc., along with 3C digital product volume is more and more littler, also released the less memory card of volume for adapting to its commodity volume manufacturer, comprised the Duo series of extending by MS and MSPRO, also have by SD, the Mini SD that the MMC specification is extended, specifications such as mini memory card such as RS-MMC and Transflash, be the volume minimum still on the market at present with the Transflash card, and MS and MSPRO camp also just actively release and Transflash card volume seemingly minisize memory card (MemoryStickMicro mutually, M2), and on the internal memory market that volume day by day dwindles, occupy a tiny space, and each memory card pattern, the size of specification is all different, so the contact design of its corresponding circuit interface is all different.
At present the circuit interface of minisize memory card (Micro SD) a is a standard for as shown in Figure 1, it is to have eight golden finger contact a1, and differed from three with 11 golden finger contact b1 that remember stub (Mini SD) b circuit interface standard, and wherein remember the tenth of stub (Mini SD) b and be planned to temporary no function with the 11 golden finger contact b1, and the 3rd of memory stub (Mini SD) b be that to be designed to function identical with the 6th golden finger contact b1, and existing form of implementation, its traditional form of terminal is opposite with the plug-in card direction, so terminal must have sufficient intensity to bear the thrust of plug-in card.In addition if the evenness of several terminals differs on the connector, and if memory card does not keep vertical direction during plug-in card, and during, cause the terminal bends distortion most probably and can't effectively contact with the skew angle plug-in card.Moreover, sufficient intensity is arranged to bear plug-in card thrust for making terminal, need use the copper material of 0.15mm thickness to make terminal on this slim memory card adapter in the past at least, and then cause the blocked up phenomenon of integral thickness behind the plug-in card.And because of the terminal intensity effect, the plug dynamics of whole connector is difficult for stable control.Moreover; existing form of implementation; have between pin position ground connection only or the two pin positions with traditional slender conductor wiring; make that the contact area of two pin interdigits is very little; and cause the slender conductor wiring to come off or other pin position of false touch; cause the damage internal storage structure; and can't effectively prevent sudden signal pulse, and then the data that can not protect internal memory inside to store, ground connection poor effect in addition; can't prevent noise jamming; moreover message transmission rate is unstable, can't improve memory card access data frequency of utilization, and because of the contact area of two pin interdigits too little; and the design of inconvenient adapter circuit and mechanism, so on using, reality still do not meet the required of user.
