Description

Memory card interface adapter {MEMORY CARD INTERFACE ADAPTER}

The present invention relates to a memory card interface adapter, and more particularly, to an adapter for converting a memory card having a STONE interface into a compact flash card (CF card) or a universal serial bus (USB) interface.

Memory cards have been steadily gaining popularity among various types of storage media because of their small size and large capacity. Since the consumption market of memory cards is so large, memory card developers and manufacturers set special standards for their own cards. Consumers can now purchase many types of memory cards, but card makers are still working on miniaturization and increasing storage capacity. Current memory cards can increase their storage capacity, but their size is limited to the original specifications. For example, the connection interface of a compact flash card (CF card) has 50 pins for electrical connection with other devices. Due to this many pin interface standard, it is difficult to reduce the size of the CF card.

Newly developed memory cards, such as STONE cards, have the advantages of reduced size and increased capacity, but they are difficult to work with current devices such as card readers because the new standard of memory cards has not been used yet. In addition, a computer is a main device that operates as a memory card, and many other types of I / O interfaces such as a high speed data transmission interface and USB have been developed. However, since most I / O interfaces of a computer do not directly correspond to a memory card, there are many limitations in applying a memory card.

The present invention relates to a memory card interface adapter devised in view of such a conventional problem.

An object of the present invention is to provide a memory card interface adapter that converts a STONE memory card into a CF card standard or a USB standard so that the STONE memory card can be accessed through another device.

In order to achieve this object, the memory card interface adapter of the present invention performs interface conversion using the elements described below.

The adapter body is formed with a chamber into which the memory card to be interfaced is inserted, and the appearance of the adapter body is the same as that of the CF card.

Place the L-shaped circuit board inside the adapter body.

The first connector of the memory card interface adapter corresponds to the memory card electrically connected to the circuit board and interface converted.

The second connector has an interface such as a CF card interface and is electrically connected to the first connector through a circuit board.

The connecting port has an interface such as a USB interface and is electrically connected to the first connector and the second connector through a circuit board.

When the memory card to be converted is installed in the adapter main body and electrically connected to the first connector, the memory card to be converted can be connected via the CF card interface or the USB interface.

Hereinafter, other objects, advantages and features of the present invention will be described with reference to the accompanying drawings.

According to Fig. 1, the adapter main body 10 has a chamber 101 into which the memory card 20 to be converted is inserted, which in this embodiment is a STONE card. A second connector 12 and a connecting port 13 are disposed at two adjacent sides of the adapter main body 10, respectively. Since both the second connector 12 and the connecting port 13 are electrically connected to the memory card 20 through the circuit board 15 (not shown), the memory may be connected through the second connector 12 or the connecting port 13. Data stored in the card 20 can be accessed. In this embodiment, the second connector 12 is a compact flash card (CF) standard and the connecting port 13 is a universal serial bus (USB) standard. Therefore, the memory card 20 can be read or written to an external device connected to the CF card interface or the USB interface.

According to Figure 2, it can be seen that the appearance and size of the adapter body 10 is made of a CF card. The adapter body 10 includes a top plate 106, a bottom plate 107, and a U-shaped frame 100 positioned between the top plate and the bottom plate. The frame 100 is composed of a first side, a second side, and a third side connected between one end of the first and second sides, and protrusions 103 are formed on the other end of the first side and the second side, respectively. do. The frame 100 also has a T-shaped portion (without code), and the three ends of the portion are respectively connected to three sides of the frame, so that the frame 100 and the portion cooperate with the first chamber 101, The second chamber 102 and the third chamber (without code) are formed. The second chamber 102 is connected to the third chamber to form an L-shaped space. A pair of gaps 105 are formed in two opposite sides of the frame 100 near the first protrusion 103, and two protrusions protruding from two opposite ends of the second connector 12 are formed in the gap. Is inserted. A second protrusion 104 is formed at one side of the frame 100, and the protrusion is connected to the second chamber 102 to receive the connecting port 13.

The upper plate 106 is L-shaped to cover the upper portions of the second chamber 102 and the third chamber. The circuit board 15 is disposed in the L-shaped space formed by the second chamber 102 and the third chamber.
