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 32 mm×24 mm×2.1 mm.
