Description

The present invention relates to a memory card connector, and in particular, SD (Secure Digital).
Card), MMC (MultiMedia Card), RSMMC (Reduced Size MultiMedia Card), mini SD (mini-Secure)
The present invention relates to a digital card) and a five-in-one memory card connector that provides connection between a TF (TransFlash Card) card and an electric circuit of an electric device.

  In recent years, storage media in the form of memory cards (or flash memory cards) are light, thin and compact, have a large storage capacity, are earthquake resistant, and have excellent re-recording characteristics, so that they can be used in information appliances, personal computers or portable digital. Widely used in products (hereinafter collectively referred to as electrical devices).

  In general, an electric device using a memory card as a storage medium, for example, a digital camera, a PDA, a digital audio player, etc., basically uses a specific memory card as a data storage medium. There are registered trademark cards, smart media (registered trademark) cards, memory stick cards, SD (Secure Digital Card) cards, MMC (MultiMedia Card) cards, and RSMMC (Reduced Size MultiMedia Card) cards. Mini SD cards and TF cards.

  For large consumers, memory cards cannot achieve effective distribution between portable digital products and electrical devices such as computer systems and computer peripherals, creating restrictions on consumers purchasing products To do. For this reason, some memory card manufacturers have developed memory cards that are compatible with existing memory card standards but are slightly smaller in size, to match the use of portable digital electrical devices with relatively small volumes. For example, the SD and MMC cards have the same outer size, and the RSMMC card chip and circuit standard (transmission agreement) are the same as the MMC memory card, but the outer size is slightly smaller than the MMC card. The mini SD card has the same chip and circuit standards as the SD card, but the outer size is slightly smaller than that of the SD card.

  The external shape of RSMMC and mini-SD card is slightly different from the above-mentioned two types of memory cards, MMC and SD. With this, the current technology can be shared with four types of memory cards: SD, MMC, RSMMC, and mini-SD at the same time. Although there are connectors that can be used, there is no connector that can handle TF cards, and compatibility requirements have been limited in the recommendation of TF cards.

  An object of the present invention is to provide a five-in-one memory card connector, which is provided with two slots overlapping on the same side of the main body of the connector, and a plurality of sets of connection terminals are disposed in the two slots, Among them, a first positioning portion for positioning the SD card, MMC card, and RSMMC card, a second positioning portion for positioning the mini SD card, and a guide device for guiding the mini SD card are provided inside the first slot. A third positioning portion for positioning the TF card is provided inside the slot, and provides a connection between the SD, MMC, RSMMC, mini SD, TF card and the electric circuit of the electric device.

According to the first aspect of the present invention, there are provided a first slot and a second slot which are superimposed on the same side of the main body, and a plurality of sets of connection terminals are disposed in the two slots. In the five-in-one memory card connector that makes up the connection,
A first positioning part for positioning the SD card, MMC card, and RSMMC card, a second positioning part for positioning the mini SD card, and a guide device for guiding the mini SD card are provided inside the first slot. A third positioning portion for positioning the TF card is provided on the inner side, and a five-in-one memory card connector is provided, which provides connection between the SD, MMC, RSMMC, mini SD, TF card and the electric circuit of the electric device. .
The invention of claim 2 is the five-in-one memory card connector according to claim 1, wherein a first set of connection terminals and a second set of connection terminals are provided in the first slot, and the first set of connection terminals is SD. , MMC, RSMMC card and connector used to connect the electrical circuit, the second set of connection terminals used to connect the mini SD card and connector electrical circuit, and the third set of connections provided in the second slot The five-in-one memory card connector is characterized in that the terminals are used to connect the electrical circuit of the TF card and the connector.

  The five-in-one memory card connector of the present invention is provided with two slots overlapping on the same side of the main body of the connector, and a plurality of sets of connection terminals are disposed in the two slots. A first positioning unit that positions the SD card, MMC card, and RSMMC card, a second positioning unit that positions the mini SD card, and a guide device that guides the mini SD card are provided, and the TF card is positioned inside the second slot. A third positioning part is provided to provide connection between the SD, MMC, RSMMC, mini SD, TF card and the electrical circuit of the electrical device.

  The basic structure of the five-in-one memory card connector of the present invention is as shown in FIGS. 1 and 2, and the connector 10 includes a main body 11 having a cartridge shape. The second slots 12 and 13 are provided so as to overlap with each other, the first and second slots 12 and 13 are used for positioning the memory card, and a plurality of connection terminals are provided in the first and second slots 12 and 13. The connection terminal is used for connection between the memory card and the electric circuit.

  The five-in-one memory card connector of the present invention constitutes a connection between the SD, MMC, RSMMC, mini SD, TF card and the electric circuit of the electric device. As a result, the entire connector 10 has the first positioning portion 121 that can position SD, MMC, and RSMMC, the second positioning portion 122 that can position the mini SD card, and the mini SD card inside the first slot 12. A guiding device 15 for guiding is provided, and a third positioning portion 131 capable of positioning the TF card in the second slot 13 is provided.

  In the present embodiment, a first set of connection terminals 141 is disposed along the deep portion of the first slot 12 of the main body 11 to be used for circuit connection between the SD, MMC, RSMMC card and the connector 10, and the first slot. A second set of connection terminals 142 is provided on one side of the connector 12 and is used for connection between the mini SD card and the electrical circuit of the connector 10. A third set of connection terminals 143 is disposed along the deep portion of the second slot 13 to serve for connection of the electrical circuit of the TF card and the connector 10.

  In addition, the guide device 15 in the first slot 12 helps to insert and position the mini SD card securely on one side where the second set of connection terminals 142 are provided. FIG. 4 shows the SD / MMC / RSMMC card and the connector 10 inserted and used with the SD card 21. The SD card 21 (including the same external MMC card) is inserted into the first slot from the front of the main body 11. 12, the guide device 15 does not affect the insertion / removal operation of the SD card 21 (including the MMC card), and the SD card 21 surrounds the first positioning portion 121 inside the first slot 12. The circuit contact of the SD card 21 is surely brought into contact with the first set of connection terminals by the limiting / guide action.
