Description

  The present invention provides a conversion connector that can mutually correspond to a memory card slot with respect to the insertion type of the memory card, and the conversion connector is a flexible connector that can flexibly correspond to the memory card and electrical contact with the memory card. The present invention relates to a structure improvement of a memory card conversion connector, characterized in that a printed circuit board is provided, production costs can be reduced and production efficiency can be improved at the same time without using terminals.

  With the progress of electronic science and technology, electronic devices of various forms spread to the world, and the functions of these devices such as personal computers, mobile phones, digital cameras, etc. used by the mass increase with the passage of time, bringing different lifestyles to people. These electronic devices require data storage devices. Initially, EPROM or battery-powered memory was used as the data storage medium. However, since flash memory has appeared on the market, it has been low in consumption, non-volatile, and earthquake-resistant. With its attractive characteristics such as high storage density, it has become a basic device in many portable electronic devices. Furthermore, with advances in semiconductor technology, the storage density and transfer speed of flash memory have grown dramatically. Finally, flash memory can replace conventional storage media such as hard disks in many fields of application.

  In addition to being able to be built in on the board of electronic devices, flash memory is used in many portable storage devices, such as memory sticks and memory cards, and the use of memory cards has been further expanded. When a device such as a digital camera or a mobile phone is shipped, the capacity of the built-in flash memory is limited, and generally it is different from 32 MB to 128 MB or 512 MB. However, the capacity of the flash memory is insufficient in the usage environment. Because it is easy, manufacturers that produce many electronic devices have an additional memory card slot on the electronic device, and the user purchases a memory card with a larger capacity (1 GB, several GB, etc.) according to use. The data storage capacity of the electronic device can be increased by inserting it into the memory slot. It has become possible to.

  The current memory card standards have become very diversified, and many major manufacturers have mixed up and designed in the format of their own standard memory cards, such as CF cards, MS cards, SD cards, MMC cards, etc. It is necessary to purchase a memory card that complies with the standard of the memory card slot of the electronic device, and it is impossible to insert a memory card with a different standard into one memory card slot.

  There are various forms and standards for memory cards, but many of the standards for memory cards are an extension of the old standard, or the form of the outer shell is similar. For example, the memory card that succeeds the CD card is MINI-CD. The memory card that succeeds the card and MMC card is the MICRO-MMC card, and the most obvious difference between the memory cards is the reduced volume, which means that the volume of the electronic device is light, thin, short, The volume of the memory card is inevitably reduced because it is developing in a smaller direction, but there are few users who can always replace the electronic device, and the standard of the memory card is constantly being updated. In the meantime, old standard memory cards are being tricked, and many electronic devices can be stored at the same time in many users or households. However, when the quantity of electronic devices increases, each electronic device needs a memory card of the corresponding standard, and the user needs to consume a large amount of money just by purchasing the memory card, resulting in wasteful waste. .

  In order to solve the above problems, a memory card conversion connector developed by a certain manufacturer is disclosed in the Republic of China Patent Gazette, publication number M271208, publication date July 21, 1994, patent name: Simulated MiniSD memory card conversion As shown in FIG. 9, the conversion connector A is composed of a lower lid A1, an upper lid A2, a connecting portion A3, and a conductive terminal A4.
