The present invention relates to a card connector, and more particularly to a card connector featuring bettered high frequency performance, reduced capacitive effect, and suppressed electromagnetic radiation interference.
Security Digital, commonly abbreviated as SD, refers to a memory card, which is widely used in portable devices, such as digital cameras, personal digital assistants (PDAs), and multimedia players. SD technology is based on the MultiMediaCard (MMC) format. The SD card has a relatively high data transmission rate and is constantly updating the standards thereof. Most of the SD cards are provided with, on a lateral side thereof, with write protection control to prevent accidental data writing in the card. Some of the SD cards even support digital copyright management technology. The size of the SD cards is generally 32 mm×24 mm×2.1 mm but would be different for different types, such as micro SD. A micro SD card is a miniaturized flash memory card. Such a kind of memory card is mainly used in mobile phones, and is advantageous in that the size is extremely small. With the increase of capacity, it has started for use in global positioning systems (GPSs), portable music players, and some flash memory devices. The size of the micro SD cards is 15 mm×11 mm×1 mm, which is about a quarter of the size of the SD cards, corresponding to the size of a finger nail, and it is also connected, by means of an adaptor, to an SD or memory stick receptacle. The SD card is also referred to as an internal storage card or a memory card in the Chinese-speaking areas.
Generally speaking, the SD card requires multiple contact points for connection, and consequently, an SD receptacle also includes multiple terminal sets, which are of the same number and corresponding to such contact points. Due to such a large number of terminals, mutual interference may be quite possibly induced between the terminals, and a capacitive effect may be generated.
