Combo connector for micro sd and micro usb/ssic thin cards

Abstract

A combo connector for Micro SD and Micro USB / SSIC thin cards includes a casing having an accommodation space to contain a thin card; a conductive terminal unit including a first conductive terminal set and a second conductive terminal set which are arranged separately at two different locations in the casing; a position member located and sliding in the casing between a first position and a second position; and a conduction unit located in the casing further including a first conductive element and a second conductive element to activate the conduction unit to recognize the thin card while an electric connection between the first conductive element and the second conductive element are established. The thin card contacts correspondingly the two conductive terminal sets while the position member is reached at the second position.

Description

technical field [0001] The invention relates to an electronic card connector, in particular to a composite electronic card connector capable of inserting electronic cards of different specifications (including MUTC cards and Micro SD cards). Background technique [0002] With the continuous growth of digital information, digital mobile devices are developing towards the trend of "thin, light and small" and "high performance, low power consumption". Therefore, the demand for small, fast and power-saving memory cards is greatly increased, such as SD cards and MMC cards. , MS card, CF card, XD card and other electronic cards of different specifications. As far as Micro SD cards are concerned, the global market demand for Micro SD cards has exceeded 1 billion pieces in 2010. [0003] In addition to the above electronic cards with different specifications, in recent years, the industry has also developed a low-power embedded memory card, MUTC card (MUTC, Micro USB / SSIC Thin Card,...

AI Technical Summary

Problems solved by technology

[0004] However, due to certain factors, such as the USB power consumption specification does not meet the low energy consumption requirements of mobile devices, and the interface bandwidth cannot be increased. For example, the LCD display specification of electronic devices has been increased from 128×64 dot matrix to 2048×1536 dot matrix , the image quality has been increased from CIF to 8MP (3264×2448 dot matrix), the memory card has been increased from 128MB to 64GB, etc. In addition, the functional requirements of electronic devices have increased greatly, and too many interfaces have caused complex hardware and software design, such as LCD screens. I / F interface 8~24-bit parallel signal not only occupies an area, but also is an asymmetrical single-ended current mode, which will generate large EMI electromagnetic radiation interference and cause poor communication quality

[0005] Therefore, if the MUTC card and the Micro SD card are to be integrated and used on the same electronic device, the technology has yet to be broken through, and as far as the currently available electronic card connectors are concerned, there is no plug-in MUTC card and Micro SD card.
