Description

  The present invention relates to a memory card connector, and in particular, SD (Secure Digital Card), MMC 4.0 (MultiMediaCard 4.0), MMC (MultiMediaCard), RS-MMC (Reduced Size MultiMediaCard), and MiniSigMide (MiniSigMidCard). The present invention relates to a five-in-one type memory card connector used for connecting a power supply and a data transmission circuit between a standard memory card pin and an electric device.

  In recent years, storage cards in the form of memory cards (or flash memory cards) have been widely used for information appliances, personal computers, or the like due to their excellent characteristics such as light weight, thinness, compactness, high storage capacity, earthquake resistance, and ability to store duplicates It is used in portable digital products (hereinafter collectively referred to as electric devices).

  In general, an electric apparatus using a memory card as a storage medium basically uses a memory card of a specific standard as a data storage medium, and the memory card standards commonly used at present are CF (registered trademark), SM (SmartMedia ( (Registered Trademark) Card), MS (Memory Stick Card), SD (Secure Digital Card), MMC (MultiMediaCard), RS-MMC (Reduced Size MultiMediaCard), etc., and in the market, SD was developed exclusively for mobile phones. -Secure Digital Card) and TF (TransFlash Card).

  However, memory cards of various standards currently on the market are not able to achieve effective distribution between consumers, such as portable digital products and computer systems, computer peripherals, and other electrical devices. This creates the problem of creating restrictions on purchases. For this reason, some memory card manufacturers have developed a memory card that is compatible with the existing memory card standard but with a slightly smaller size to match the use of portable digital electrical devices with a relatively small volume.

  For example, SD and MMC are memory cards having the same outer size, and the chip and electrical standard (transmission agreement) of the RS-MMC memory card are the same as those of the MMC memory card, but the outer size is slightly smaller than that of the MMC memory card. Although the miniSD memory card has the same chip and electrical standards as the SD memory card, the external size is slightly smaller than that of the SD memory card.

  In particular, MMC 4.0 memory cards have recently appeared on the market in order to increase the transmission speed in response to the large capacity demands of devices such as cellular horns, DSCs, DVCs, etc. This is due to the improvement in the transmission speed of MMC memory cards. The number of pins has been changed from 9 pins to 13 pins. Compared to the MMC and SD memory card 4-bit data transmission format, MMC 4.0 transmits 8-bit data. In other words, the increased number of 4 pins in the MMC 4.0 memory card can provide more data transmission channels, thus increasing the transmission speed to meet the demands of large capacity transmission of electrical devices, as well as a sufficiently old standard Compatible with

  The external shape of MMC4.0, RS-MMC, miniSD memory card is slightly different from the above-mentioned two types of memory cards, MMC and SD. Therefore, from the existing technology, SD, MMC, RS-MMC, There is a multi-memory card connector that can share four types of miniSD memory cards. However, there is not yet a connector that can use the MMC 4.0 memory card, so that there is a limit to the application of MMC 4.0 and the application device of the old standard.

  Furthermore, the main body of the multi-memory card connector must be equipped with a slot (or related positioning structure) that can position the corresponding memory card securely, and must have a good terminal structure design. A connection can be configured to the memory card and the circuitry of the electrical device.

  A multi-memory card connector that can insert various types of memory cards on the market is limited by the problem of terminal structure design, and therefore cannot be inserted in the same direction when the memory card is inserted into the connector. That is, a certain memory card is inserted with the memory card terminal facing downward, and another memory card is inserted in the opposite direction with the memory card terminal facing upward. This causes confusion for the consumer, and it is necessary to confirm whether the insertion direction is correct when inserting the card, which is considerably inconvenient in use.

  An object of the present invention is to provide a kind of five-in-one memory card connector, which is provided with a slot in the main body, and this slot has five types of memory: SD, MMC 4.0, MMC, RS-MMC, and miniSD. Any kind of memory card of the card can be inserted, a first terminal set is provided in the middle part of the slot, and pins of the SD, MMC 4.0, MMC, and RS-MMC memory cards are connected to the first terminal set. The second terminal set is provided in the deep part of the rear stage of the slot and can be electrically connected to the pins of the miniSD memory card. In addition, the third terminal set is provided in the front part of the slot. And can be electrically connected to the data pins of the MMC 4.0 memory card.

  The purpose of the present invention is to insert any of the above five different types of memory cards, and the first to third terminal sets are located below the slots, and each memory card is pinned. It is to provide a five-in-one type memory card connector that can be inserted in a downward direction and can achieve a convenient function without causing confusion to the user.
