Description

  The present invention relates to a memory card adapter, and more particularly, to a small memory card adapter that can read a small memory card (for example, a micro flash) through a standard memory card (for example, SD memory card) interface.

  Recently, various digital electronic devices such as digital players, digital cameras and multi-function mobile phones are on the market. These electronic devices are always multifunctional and require large capacity storage media. Memory cards of different sizes and specifications have been developed such as SM (Smart Media Card), MMC (Multimedia Card), SD (Secure Digital Memory Card), XD (xD Picture Card) and MS (Memory Stick). However, with the development of smaller digital electronic devices, efforts for miniaturization are still being made. Mini SD, RS-MMC (reduced size multimedia card) and micro flash were developed for smaller products.

  However, a memory card smaller than the standard is not compatible with a device having a standard interface. Therefore, a memory card adapter must be used to correlate the small memory card and the standard interface.

  As shown in FIGS. 7 and 8, the mini SD card adapter includes a base 80 having two side walls, a positioning tab 86, and an end of the base 80 opposite to the side receiving the mini SD card (hereinafter referred to as “far end”). A circuit board 87 provided in the section, a first cover 88 made of a thin metal plate, and a second cover 89.

  The base 80 has a socket 81 formed at an end portion (hereinafter referred to as “near end portion”) on the side for receiving the mini SD card in order to receive the mini SD card. At the far end of the base 80, a plurality of through holes 82 are arranged at equal intervals. The base 80 has two fastening members 83 formed on the outer surface of each side wall. One of the side walls is formed with a mounting groove 84 that partially communicates with the socket 81. Each of the two tab holes 85 is formed at the top of each side wall.

  The positioning tab 86 has a protrusion 860 formed at the center thereof, and is provided in the mounting groove 84. The mini SD card received in the socket 81 can be positioned by the protrusion 860.

  The circuit board 87 at the far end of the base 80 has a plurality of contacts (not labeled) on the bottom surface corresponding to the through hole 82, and a plurality of pins from the near end of the circuit board 87. 870 extends to the socket 81 so as to be electrically connected to the mini SD card.

  The first cover 88 has two folded edges 880 each provided on each of two opposite sides, and each edge 880 is connected to the fastening member 83 on the side wall of the base 80. Two corresponding holes 881 are provided. Two tabs 882 are formed on each of the two side portions at the proximal end of the first cover 88. The tab 882 is inclined inward and has a slightly wider width than the tab hole 85. When the first cover 88 is attached to the base 80, the four fastening members 83 are inserted into the four holes 881, and the two tabs 882 are tab holes 85 for fixing the first cover 88 to the base 80. Inserted into.

  The second cover 89 is attached on the first cover 88 at the far end of the base 80.

  A mini SD card adapter is formed with the above elements to accept a mini SD card. The mini SD card adapter can be inserted into a standard SD interface, so that the mini SD card can be used in a device equipped with a standard SD interface.

  However, the positioning tab 86 for positioning the mini-SD card is an additional element that requires a mounting groove 84 formed in the base 80, and requires additional molding, thereby increasing manufacturing costs.

  As shown in FIG. 9, another conventional mini SD card adapter has a positioning tab, and the positioning tab has the same function as the positioning tab 86 of the conventional mini SD card adapter described above.

  Therefore, the present invention provides a small memory card adapter that can reduce or eliminate the above problems.

  The main object of the present invention is to provide a small memory card adapter including a base, a connection module, a cover, and a metal panel.

  The base has a socket formed at the near end, and a positioning tab is integrally formed on the inner surface of the socket to fix the inserted small memory card. While having the same function, the mounting groove and the step of mounting the positioning tab can be omitted. Therefore, the small memory card adapter according to the present invention simplifies the manufacturing process, increases its usefulness, and reduces the manufacturing cost. Can be reduced.

  A contact protrusion extends from the edge of the metal panel and bends to contact the bottom surface of the metal panel corresponding to the opening of the cover. The contact protrusion is connected to a ground point through the opening for grounding. Since the metal panel prevents EMI interference, it is more efficient than conventional adapters.

  Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

  1 to 3, the small memory card adapter includes a base 10, a cover 20, a connection module 30 provided between the base 10 and the cover 20, and a metal panel 40.

  The base 10 has a socket 11 formed at the proximal end for receiving a small memory card, which is integrally formed on the inner surface of the socket 11 for fixing the inserted small memory card and It has a trapezoidal positioning tab 110 protruding from the inner surface. A plurality of through-holes 12 are provided at the far end of the base 10.

  The connection module 30 includes a printed circuit board 31 having a plurality of contacts 32 provided at a far end corresponding to the through-hole 12 of the base 10, and the small memory card adapter is electrically connected to an external device by the contacts 32. Connected. A plurality of connection pins 33 are provided at the near end portion of the printed circuit board 31, the far end portion of the connection pins is connected to the contact 32, and the near end portion is electrically connected to the small memory card. It is fixed to the socket 11. A ground point 34 is provided on the top surface of the printed circuit board 31 and connected to one of the contacts 32.

  In this embodiment, the cover 20 is attached to the base 10 so as to form a standard SD memory card. The cover 20 has a recess 21 formed on the top surface thereof, and a plurality of notches 22 are provided at the edge of the recess, and each notch 22 is formed on one of its inner surfaces. A protrusion 220 is provided. In this embodiment, the protrusion 220 is semicircular and has a thin top and a thick bottom so as to form an inclined surface. Further, an opening 23 is provided in the recess 21 through the cover 20.

  The shape of the metal panel 40 corresponds to the shape of the recess 21, and a plurality of tabs 41 extend downward from the edge of the metal panel 40, and each tab 41 has a semicircular opening corresponding to the protrusion 220. Further, the contact protrusion 42 extends from the edge of the metal panel 40 and bends toward the bottom surface of the metal panel 40 corresponding to the opening 23 of the cover 20.

  When the base 10, the connection module 30 and the cover 20 are assembled, the contact 32 is fixed to the corresponding through-hole 12 so as to be electrically connected to an external device, and the proximal end portion of the connection pin 33 is The socket 11 is fixed so as to be electrically connected to the small memory card. The metal panel 40 is fixed to the recess 21, and the contact protrusion 42 is connected to the ground point 34 through the opening 23 as shown in FIG. 4.
