Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an adapter for a small memory card, and more particularly to a device for making the latest small memory card (Mini SD) compatible with an existing SD expansion slot.
[0002]
[Prior art]
As the development of digital products progresses, for example, PDAs, digital video cameras, digital cameras, and the like are gradually becoming popular. The advantage of such a digital product is that it has an expansion slot, for example, by connecting and connecting various memory cards such as CF (Compact Flash), SM (Smart Media (registered trademark)), SD (Secure Digital), and MMC. , To enhance the functionality of the product.
However, in order to improve the restriction due to the large volume of the CF memory card, the industry has introduced an MMC card having the same volume as the SM memory card and a slightly thicker thickness. The new MMC memory card overcomes the drawback of the slow read / write speed of the CF card, but is relatively expensive initially because few IA products support it.
[0003]
Furthermore, as the demand for digital copyright protection has increased, an SD memory card that has an encryption function and has the same shape as the external shape of the MMC has appeared, which simultaneously has multiple functions such as high-speed transmission and data encryption. In addition, the hardware supporting the SD memory card also has the backtrack compatibility characteristic of the MMC memory card.
FIG. 1 is a diagram showing the use of a conventional SD card 102 for a PDA 100. Since the thickness of the SD card 102 is larger than that of the SM card and takes up more space, a new small SD card 3 having a smaller volume than the conventional SD card 102 has appeared. Because they are not compatible, existing digital products have a problem that they cannot enjoy the practicality and functionality provided by the small SD card.
[0004]
[Problems to be solved by the invention]
In solving the above-described problems, the present invention has a main object of adapting a latest small-sized SD memory card to an existing SD expansion slot by using an adapter to enhance compatibility with digital products.
[0005]
[Means for Solving the Problems]
Technical means for solving the problems according to the present invention to achieve the above object include a main body, an upward-opening box, and an elastic fastening member.
The main body is composed of a combination of a base and a top lid, and has the same outer shape as an SD memory card, and can be inserted into a general SD expansion slot. At the front end of the base, a plurality of terminal blocks capable of receiving a plurality of terminals are provided, and a receiving groove is provided adjacent to the terminal block for receiving a small memory card, and the rear end of the terminal extends to the surface of the receiving groove. The base is extended, and a positioning portion and a concave portion are formed on the side of the base. The upper lid is provided with a through groove corresponding to the shape of the housing groove of the base, and a cut groove and a notch are formed on the side of the frame.
[0006]
The top-opening box has a generally zigzag shape and is provided adjacent to the terminal block. Lugs are provided on both side edges at the front end of the box, and the box is hooked on a pivot groove provided between the base and the top cover. The box can be opened upward by a certain angle around the lugs on both sides. An outwardly projecting engaging portion is provided at a side end of the box, and the engaging portion is disposed in a concave portion of the base, and an upper portion thereof corresponds to a notch of an upper lid.
The elastic fastening member has a rear end fixed to the positioning portion of the base, a pressing portion protruding outward at the middle portion is exposed in a cut groove of the upper lid, and a locking pressing portion at the front end is engaged with the box. Press on the part.
[0007]
[Embodiment of the invention]
As shown in the exploded view of FIG. 2, the adapter of the small memory card disclosed in the embodiment of the present invention has the following.
The main body 1 is composed of a base 11 and an upper lid 12, and its outer shape is the same as that of the SD memory card, that is, it can be inserted into the general SD expansion slot 101 shown in FIG. A plurality of terminal blocks 111 are provided at the front end of the base 11 for accommodating a plurality of terminals 2, and the front end 21 of the terminal 2 is fitted into a slot 112 penetrating therethrough, and a part thereof is formed on the base. 11 has a function of protruding from the bottom edge surface and electrically contacting the expansion slot 101.
[0008]
An accommodation groove 113 is provided adjacent to the side of the terminal block 111 to accommodate the small memory card 3. The small memory card 3 is a small SD card, and the rear end 22 of the terminal 2. Extends to the surface of the accommodation groove 113, and a positioning portion 110 and a concave portion 114 are formed on one side of the side frame of the base 11. The upper lid 12 is provided with a through groove 121 corresponding to the shape of the housing groove 113 of the base 11, and a cut groove 122 and a notch 124 are formed on the side of the frame.
[0009]
The upper opening type box 4 is formed of metal, has a substantially zigzag shape, is provided adjacent to the terminal block 111, and lugs 41 are provided on both side edges at the front end thereof, and the base 11 and the upper lid 12 are provided. The box body 4 is configured such that the rear end thereof is opened upward by a certain angle with the lugs 41 on both sides as the axis (see FIG. 8). . Further, on the left side of the box body 4, a guide piece 42 that opens outward is provided in accordance with the gradually decreasing frame slopes 116 and 123 of the base 11 and the upper lid 12, and a hook portion 43 that protrudes outward is provided on the right end. It is installed, and the above-mentioned hooking part is placed in the recessed part 114 of the base 11, and the upper part thereof corresponds to the notch 124 of the upper lid. At least one elastic restrictor 44 that contacts the receiving groove 113 is provided.
[0010]
The elastic fastening member 5 is formed of a metal piece, and its rear end 51 is fixed to a positioning portion 110 of the base 11 when the upper lid 12 is coupled to the base 11 by high frequency, and a pressing portion 52 protruding outward at a middle portion. Is formed so as to be pressed by the cut groove 122 of the upper lid 12, and the locking pressing portion 53 at the front end is pressed above the locking portion 43 of the box.
[0011]
The small memory card 3 is mainly composed of the latest small SD card. The front end 31 of the small memory card 3 can be inserted into the open-top box 4, and the bottom surface thereof is in contact with the terminal rear end 22 to be electrically connected.
