The present invention relates to a memory card assembly. More particularly, the present invention relates to a memory card assembly including a memory card and a case for accommodating the memory card.

Electronic cards are widely used in computers and electronic dictionaries to extend small computer system interfaces (SCSI) such as memory, network cards, modems and high-speed hard disks, scanners, and the like. In addition to personal computer memory card internally-relevant (PCMCIA) cards, electronic cards for use in personal digital assistants (PDAs), portable electronic dictionaries, digital cameras, and the like can be used in multimedia media (MMC), compact flash cards (CF), and smart cards. Media card (SMC), memory stick (MS), secure digital memory card (SD).

However, most memory cards have a specific specification of interface, and therefore cannot be used with the connection interface of the widely used Universal Serial Bus (USB) specification. 1 shows a dual interface memory card 90 comprising a USB interface and a read / write interface 92 at each end. A user can couple a USB interface with a USB socket 93 of an electronic device (not shown) or use a read / write interface socket (not shown) and a read / write interface 92 to read / write data. Can be coupled.

A typical dual interface memory card 90 has a uniform thickness designed for an end with a read / write interface 92 that is generally larger than the thickness of the standard coupling opening of the USB socket. Thus, the other end of the memory card 90 having the USB interface 91 is too thick to match the coupling opening 94 of the USB socket 93. As a result, when the end of the memory card 90 is inserted into the coupling sheet 95 inside the coupling opening 94 of the USB socket 93, the USB interface 91 becomes the elastic conductive material of the USB socket 93. It is not possible to reliably electronically contact the plate 96. In addition, the memory card 90 is loosely coupled with the USB socket 93 so that the memory card 90 is easily separated from the USB socket 93.

The memory card assembly according to the present invention includes a memory card and a case. The memory card includes a first end and a second end having a USB interface. The case includes a compartment for removably receiving the second end of the memory card. The case also includes a coupling member extending from the wall defining the compartment. When the second end of the memory card is inserted into the compartment of the case, the coupling member and the first end of the memory card together form a coupling socket for coupling the coupling sheet inside the coupling opening of the USB socket, The USB interface is located in the coupling socket and makes electrical contact with the contacts of the USB socket.

2 to 6, the memory card assembly according to the present invention includes a memory card 10 and a case 20 in which the memory card 10 is removably received. The memory card assembly engages with the coupling opening 31 of the USB socket 30 (see FIG. 7) and reliably contacts the elastic conductive plate 33 of the coupling sheet 32 inside the coupling opening 31. To provide.

4 and 5, the memory card 10 includes a first end 11 and a second end 12. The USB interface 13 is provided at the first end 11 of the memory card 10 and includes a plurality of contacts 15.

2, 3 and 6, the case 20 includes a compartment 21 into which the second end of the memory card 10 is inserted. The case 20 also includes a coupling member 22 extending from the wall defining the compartment 21. Preferably, the coupling member 22 has an end face aligned with the end face of the first end 11 of the memory card 10 coupled with the case 20. The coupling member 22 and the first end 11 of the memory card 10 together form a coupling socket 23 for coupling with the coupling opening 31 of the USB socket 30. 7)

The memory card 10 may include a USB interface 13 for use only as a USB memory card. Nevertheless, the memory card 10 may include a USB interface 13 and a read / write interface 14 (see Fig. 4). The read / write interface 14 may include an SD read / write interface and an MS read. / Recording interface or other formats. Nevertheless, the read / write interface 14 of the memory card 10 must be converted to the standard read / write interface via an adapter (not shown) for coupling with the standard read / write socket.

In another example shown in FIG. 8, the memory card (shown at 101) includes the MINI SD read / write interface 141 of the standard specification. In another example shown in FIG. 9, the memory card (newly shown at 102) includes an MS DUO read / write interface 142 of standard specification.

2 and 7, in use, the second end 12 of the memory card 10 has the first end 11 of the memory card 10 and the coupling member 22 of the case 20 together. A coupling socket 23 for coupling with the coupling seat 32 inside the coupling opening 31 of the USB socket 30 is formed and inserted into the compartment 21 of the case 20. The USB 13 and its contacts 15 are located in the coupling socket 23 for reliable contact with the resilient conductive plate 33 of the USB socket 30, so that the memory card 10 and the case 20 Improve electrical contact stability while preventing separation from the USB socket 30.

2, 3 and 6, the coupling member 22 of the case 20 includes a horizontal plate 24 and two lateral plates 25 on each of the two lateral sides of the horizontal plate 24. do. When the second end 12 of the memory card 10 is inserted into the compartment 21 of the case 20, the first end 11 of the memory card 10 is positioned opposite the horizontal plate 24, Thus, the coupling socket 23 is formed. Each of the two lateral sides of the case 20 may comprise an arc-shaped recess 27. In addition, the compartment 21 of the case 20 extends through the arc-shaped recess 27. By this configuration, the user can hold the second end 12 and the case 20 of the memory card 10 at the same time, and the case 20 is held by the arc-shaped recess 27 so as to hold the USB socket 30. ) Facilitates smooth removal of the memory card (see FIG. 7).

5 and 7, positioning means are provided between the second end 12 of the memory card 10 and the compartment 21 of the case 20. In this example, the second end 12 of the memory card 10 includes a hole or recess 16 such that the wall defining the compartment 21 of the case 20 is coupled with the recess 16. And projections 26 for the same.

10-12 show a modified embodiment of the memory card assembly according to the present invention. In this embodiment, the coupling member 22 of the case 20 is connected to the other horizontal plate 29 and the first end 11 of the memory card (indicated here by 103) which interacts with the horizontal plate 24. And a lateral plate 25 for forming a rectangular hollow frame for receiving (). The memory card 103 may include a MICRO SD read / write interface 143 or a MICRO MMC read / write interface. The case 20 also includes a slot 281 on the side and in communication with the compartment (indicated here by reference numeral 221) so that the user can grasp and pull out the memory card 103 and the case 20, At the same time, the memory card assembly is removed from the electronic device (not shown). The compartment of the case 20 also extends to a coupling member 22 for receiving the first end 11 of the memory card 103.
