Description

Improved 5-in-1 memory card connector structure

technical field

The utility model relates to an improved five-in-one memory card connector structure, in particular to a five-in-one memory card connector which can be inserted into a single slot for SD, XD, MS, MMC or MMC4.0 memory cards.

Background technique

Since electronic consumer products such as digital cameras, PDAs, and MP3 players became popular, it has also led to the vigorous development of storage media memory cards. However, various manufacturers have developed memory cards of various specifications for different needs. Among them, It has high acceptance in the market, and the most used groups are SD (Secure Digital), XD (Xd-Picture Card), MMC (MultiMedia Card), MS (Memory Stick Card), and MMC4.0, etc. The card structure, therefore, as a bridge role between the memory card and mobile electronic products - the connector, of course must also be designed along with the above memory card structure. And the design of said connector is of course based on the design of lightness and convenience, and utilizes the similar characteristics of memory card body structure between the same type to design a shared multi-in-one connector, but said multi-in-one There are still many disadvantages in the use and manufacture of the connector, such as: due to the small size of some memory cards, when inserting the connector, there are often incorrect angles that cause the memory card to not be used smoothly, or the memory card is even a part of the machine. damage. Furthermore, for the relatively new MMC4.0 memory card, due to the speed of transmission and the advantages of low power consumption of the said memory card, it has become the mainstream trend of the next-generation memory card, and it is more than the original memory card. The MMC memory card adds four gold finger contacts. Of course, its corresponding reading connector must also add four corresponding terminals. Or support, how to design a connector that meets the needs of consumers is a big challenge.

Therefore, the inventor of this case has carefully studied and accumulated many years of personal experience in the above-mentioned business, and finally designed a new and improved five-in-one memory card connector structure. , upper cover and array terminal group, when memory cards of different specifications such as SD, MMC, MMC4.0, MS and XD are inserted and used, they can automatically Identify and guide the corresponding slot where the memory card is inserted, and the switch device on the side of the main bracket is forced to conduct due to the inward sliding of the card ejection bracket, so that the connection between the memory card and the connector can be carried out. Furthermore, the above-mentioned memory card inserted in the connector can be quickly and conveniently taken out by using the card ejection mechanism at an appropriate position of the card ejection bracket.

Contents of the invention

The purpose of this utility model is to provide an all-in-one connector structure that only has a single slot and can be used to read memory cards of different specifications such as SD, MMC, MMC4.0, MS, and XD.
