Abstract: A micro SD adapter structure includes a casing having an insert slot, a hollow portion at the casing, an embedding groove at the hollow portion, a plurality of sunken grooves corresponding to the hollow portion, a connecting base proximate to each sunken groove; a transmitting interface at the hollow portion and having a plurality of contact portions, a terminal module at the embedding groove and having a fixing base, a plurality of terminals on the fixing base, and an end of each terminal electrically coupled to each contact portion on a surface of the connecting interface and another end corresponding to the plurality of sunken grooves; and a latch unit on the connecting base. The micro SD card can be secured into the insert slot to achieve a better electric transmitting effect and swap the micro SD card immediately when the micro SD card is inserted into the insert slot.

Abstract: The present invention provides an improved packaging structure of a memory card, such as mini SD memory card. The packaging structure comprises a substrate having a plurality of integrated circuit devices and passive devices located therein, and a metal cover having an insulating layer formed on a top portion of the metal cover. A plurality of protruding plates bending downward are formed around a circumferential area of the metal cover, and a roll-shaped fixing part is formed at a bottom portion of a particular protruding plate. The roll-shaped fixing part and the protruding plates are utilized to engage the frame with the metal cover to form a sealed structure so that the frame covers all the protruding plates and the roller-shaped fixing part of the metal cover. The integrated circuit devices and the passive devices are located within the space of the frame to form a mini SD memory card package.

Abstract: A micro SD adapter structure includes a casing having an insert slot which is a hollow structure in the shape of a mini SD card, a hollow portion at the casing, a plurality of fixing grooves on the casing and corresponding to the hollow portion, a plurality of sunken grooves on the hollow portion, a connecting base proximate to each sunken groove; a transmitting unit having a conducting interface on the hollow portion and the conducting interface is electrically coupled to a plurality of terminals which are installed in the fixing groove of the casing and corresponding to a plurality of sunken grooves; and a latch unit disposed on the connecting base. The micro SD card can be secured into the insert slot to achieve a better electric transmitting effect and swap the micro SD card immediately when the micro SD card is inserted into the insert slot.

Abstract: A MICRO SD card includes a casing composed of a base and a top cover, an insertion slot is defined in an end of the casing and a plurality of first recesses are defined in an inner surface of the base. A recessed area is defined in the inner surface of the base so as to receive a circuit board therein. The top cover has a plurality of ridges extending from an underside thereof and each ridge has a second recess defined therein. A plurality of terminals each have a projection which is engaged with one of the second recesses. A first leg and a second leg respectively extend from two ends of each of the projections. The first leg extends into the insertion slot and the second leg has a protrusion which is compressed onto the circuit board by the ridge corresponding thereto.

Abstract: The present invention provides a micro security digital card including: a first shell having a receiving space; a second shell with a periphery thereof forming an embedding part; an integrated circuit with one side thereof provided with a plurality of contacts; and an intermediate element disposed between the second shell and the integrated circuit. The receiving space of the first shell sequentially receives the second shell, the intermediate element and the integrated circuit. The embedding part of the second shell is embedded into the first shell such that the second shell tightly combines with the first shell. The integrated circuit tightly combines with the second shell by means of the intermediate element.

Abstract: A multimedia memory card comprises a case cover, a body and a circuit board. A first inserting portion perpendicularly extends from one edge of the case cover. A second inserting portion extends from one end of the first inserting portion. The body has a holding space therein and a supporting baffle formed on inner sides thereof. The circuit board is provided with an electronic component on one surface thereof. The electronic component is received in the holding space of the body. The circuit board is joined onto the supporting baffle on inner sides of the body. The case cover is joined onto one side of the body, and the first inserting portion and the second inserting portion are inserted inside the body, thereby making the case cover and the body tightly joined together.

Abstract: A multimedia memory card comprises a cover body having a top surface and a side wall extending from the periphery of the top surface and a control circuit. The top surface and the side wall form a holding space. The circuit board has at least a first flash memory, a second flash memory, a control chip, and a plurality of passive components. The first flash memory is disposed adjacent to the second flash memory. The control chip and the passive components are disposed on one side of the first flash memory or second flash memory. The holding space of the cover body is designed to hold the first flash memory, the second flash memory, the control chip, and the passive components of the circuit board.
