Description

  The present invention relates to a design for a connector applicable to various types of memory cards, and particularly refers to a fine design of a connector applicable to five types of memory cards such as SD, MMC, XD, SMC, and MS.

  At present, the information, electronic and consumer electronics products on the market are expanding the range of application and dosage by the data access function. Data access is requested in the mode of the mainstream memory card. The types of memory cards that can be easily seen in the market are research and development by each company, and there are about five types and standards. That is, MS (Memory Stick), SD (Security Digital), MMC (Multi-Media Card), SMC (Smart Media (registered trademark) Card), XD, and the like are exemplified. These five types of memory cards not only differ in appearance size, but also in the number of pins (the number of lead contacts). As a result, manufacturers of information electronic products can only select and use one type of memory card if it is a type of electrical product, and cannot apply two or more types of memory cards. When the cause is investigated, it can be determined that the existing connector of the conventional memory card is quite fine. Therefore, all the related companies of the connector develop and manufacture a connector applicable to various types of memory cards.

  However, all the existing configurations of the conventional connector of the conventional memory card all have a number of insertion slots arranged at the end of a rectangular insulating base in a graded manner. Terminal groups are installed on the upper and lower surfaces of the insertion slot, respectively, so that they can be applied to different types of memory cards. As a result, the connector of the assembled memory card has a considerable thickness, which makes it difficult to apply to light and thin electronic products such as PDAs, electronic dictionaries, and microcomputers. In addition, since the insertion slots are provided so as to overlap each other in a class manner, two memory cards cannot be inserted and used in the same connector at the same time, and the expansion effect is extremely limited.
