(a) Field of the Invention
The present invention relates to an adapter card structure, and more particularly to an adapter structure for adapting a Mini SD/Micro SD (Secure Digital) card to an SD card.
(b) Description of the Prior Art
A Memory card has become a new focus of existing storage media, which is provided with merits of small size and large capacity. In addition, a data transmission speed of the memory card is also very fast, which can perform data writing and reading at a speed of 10 MB per second.
There are many kinds of memory cards in the existing market, including an XD (extreme Digital Picture) card, an MMSD (Multi-Media Secure Digital) card, an SD card, an MMC (Multi-Media Card) card, a CF (Compact Flash) card, an MS (Memory Stick) card, and an SM (Smart Media) card. The primary differences among the aforementioned various types of memory cards are the storage format and the size.
However, when the memory card is performing data writing and reading, it should be through a connection with a card reader and an access device to achieve a purpose of data writing and reading. Accordingly, a three-in-one, a five-in-one, and a seven-in-one card readers are provided in the market to integrate all kinds of memory cards for performing data exchange through the card reader, so as to provide data writing and reading for many memory cards of different specifications by the multi-in-one card reader.
Although the multi-in-one card reader can provide data writing and reading for many memory cards of different specifications, there is still a kind of Mini SD/Micro SD card which cannot directly perform data transmission and exchange through the card reader and the access device, but have to adapt to a specification of an SD card through an adapter card, in order to perform data exchange and transmission through the card reader and the access device.

However, when the Mini SD card 20 is inserted into the adapter card 10, an extension arm 30 made of a metallic material (normally Copper) is further installed inside the adapter card 10 at a position corresponding to an edge of the slot 13 to avoid a fall-off of the Mini SD card 20. The extension arm 30 is formed by extending down the metal terminal 14 on the adapter card 30. A hook 31 is located on a tail end of the extension arm 30, so as to hook the Mini SD card onto a notch 21 at a side of the Mini SD card 20 upon inserting the Mini SD card 20 into the slot 13, thereby avoiding a fall-off of the Mini SD card 20.
However, as the extension arm 30 is formed by extending down the metal terminal 14, it will cause an inconvenience in manufacturing the metal terminal 14, and the metal terminal 14 should also be made into a small and thin shape, which is easily to be broken in assembling, thereby inducing an inconvenience in assembling, and increasing an imperfection rate and manufacturing cost of the product.
The primary object of the present invention is to provide an adapter card structure wherein a hook formed integrally is located at a side of the adapter card to firmly latched an Mini SD/Micro SD card into the adapter card upon inserting the Mini SD/Micro SD card on the adapter card, in order to avoid a fall-off of the Mini SD/Micro SD card, thereby achieving functions of reducing manufacturing cost, increasing a productivity and a perfection rate of the product.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

A groove 15 is located at an edge, which is corresponding to a top end of the casing 11, of the slot 13, and a stick 16 which is formed integrally with the casing 11 and extending from a front end to a rear end, is located in the groove 15, so as to create a state of elastic restoring to the stick 16 in the groove 15. A projection part 17 facing the slot 17 side is at a tail end of the stick 17.
Referring to
It is worth to mention that the groove 15 and the stick 16 disclosed in the present invention are formed integrally by performing an injection molding process to the casing 10, and the state of elastic restoring can be created to the stick 16 in the groove 15, so as to quickly perform an insertion and pulling during inserting and pulling out the Mini SD card 20.
Moreover, the stick 16, which is formed integrally with the casing 11 by the process of injection molding, is used to replace a conventional extension arm made by a metallic material, which not only can improve a problem of easy to break off the metallic material during a manufacturing process, but also can increase a perfection rate and a productivity of the product, as well as largely reduce a manufacturing cost of the adapter card.
Accordingly, referring to
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
