[0003] (b) Description of the Prior Art

[0004] The current popularity of 3C (computer, communications and consumer electronics) digital products, such as digital cameras, PDAs (personal digital assistants), MP3 (media player) personal stereos, have driven the vigorous development of flash memory cards and the derivation of a variety of memory cards having different size, form and specifications. The current most common memory card specifications include SM (Smart Media), xD-Picture Card, CF (Compact Flash), MD (Micro Drive), MS (Memory Stick) and SD (Secure Digital), MMC (Multi Media Card), and so on. However, with the increasing miniaturization of 3C digital products, manufacturers have released mini memory cards having substantially smaller size specifications, including the MS and MS PRO (Memory Stick PRO) extended Duo series, and the extended miniSD, RS-MMC (Reduced Size Multi Media Card) and Transflash derived from the SD and MMC specifications. The Transflash card, however, is still the smallest memory card in the current market, and the MS and MS PRO camps are actively promoting a memory stick micro card (Memory Stick Micro, M2) similar to that of the Transflash card. Nevertheless, continuous miniaturization of memory cards occupies a small area of the core market, and size of each type of memory card having different structural form and specifications differs or configuration of circuit port contact points varies.

[0005] Referring to FIG. 1, which shows a circuit port of a current memory stick micro card (M2) a provided with eleven gold contact points a1 and a circuit port of a short memory card (MS) b configured with ten gold contact points b1, one less than the memory stick micro card (M2), wherein a first and second gold contact point a1 of the memory stick micro card (M2) a are temporarily non-functional, and a first and tenth gold contact point b1 of the short memory card (MS) b are configured with the same function. Hence, the inventor of the present invention having accumulated years of experience in related arts, attentively and circumspectly carried out extensive study and exploration to ultimately design a new improved card adapter structure that facilitates converting the relatively small sized memory stick micro card (M2) into a relatively larger sized short memory card (MS) to facilitate inserting into a digital product provided with a short memory card (MS) circuit port for use thereof.

[0006] A primary objective of the present invention is to provide an improved card adapter structure that uses a structural assembly of an upper cover, a lower cover, a set of converter terminals and a set of positioning flexible strips to enable converting a memory stick micro card of relatively small size into a short memory card of relatively larger size to facilitate inserting into a digital product provided with a short memory card circuit port for use thereof, thereby achieving effectiveness of providing a structure that can be simply and quickly assembled, enables solid emplacement of component members and is convenient to use, and substantially improving practicability and convenience of the entire configuration.

[0007] Another objective of the present invention is to provide the improved card adapter structure with a structural configuration that enables a plastic injection molded fixed seating to fixedly cover each terminal of the set of converter terminals, thereby firmly positioning each of the terminals of the set of converter terminals, and to use a plurality of slots defined in the fixed seating, to provide for cutting out connecting sections between each of the terminals after the fixed seating has been molded and prevent deformation due to assembly stress, moreover, provide the improved card adapter structure with a structural configuration that is in accordance with requirements for fast production and stable quality, and improves practicability of the entire configuration.

[0008] Yet another objective of the present invention is to provide the improved card adapter structure with a structural configuration wherein each of the terminals of the set of converter terminals supersedes the gold contact points of a traditional circuit board, thereby reducing quality control problems caused by multi-operation assembly, and providing a substantial saving on costs.

[0009] Yet another objective of the present invention is to provide the improved card adapter structure with a structural configuration wherein the plurality of slots defined in the fixed seating simultaneously provide an excellent heat dissipation effect which increase safety and practicability of the entire structural configuration.

[0010] In order to achieve the aforementioned objectives, the card adapter structure of the present invention comprises an upper cover, a lower cover, a set of converter terminals and a set of positioning flexible strips. The upper cover has an external form designed to conform to short memory card (MS) specifications, and an insertion slot is defined at a rear end of the upper cover corresponding to the shape of a memory stick micro card (M2). Fixing portions are located on two sides of the insertion slot; moreover, a positioning structure is located on a bottom surface of the upper cover. The lower cover has an external form designed to conform to short memory card (MS) specifications, and a front end of the lower cover is configured with a short memory card (MS) port. An opening is defined at a rear end of the lower cover to accommodate a memory stick micro card (M2), and fixing portions are located on two sides of the opening. Moreover, a positioning structure is located on edges of the lower cover corresponding to the upper cover. The set of converter terminals is configured with ten terminals, and an injection molded fixed seating fixedly covers each of the terminals of the set of converter terminals. Ten electrical contact points extend outward towards the short memory card (MS) port, and nine electrical contact points extend outward towards the memory stick micro card (M2) opening. The set of positioning flexible strips are correspondingly disposed between the fixing portions of the lower cover and the upper cover. Such a structural configuration enables converting a memory stick micro card of relatively small size into a short memory card of relatively larger size to facilitate inserting into a digital product provided with a short memory card circuit port for use thereof. Hence, the present invention has the effectiveness of providing a structure that can be simply and quickly assembled, enables solid emplacement of component members, will not easily deform, saves on costs, has stable quality and excellent heat dissipation and is convenient to use, thereby improving practicability, convenience and safety of the entire structural configuration.
