Convertor brings harmony to mobile cards

A miniSD card conversion adapter allows the use of microSD cards in legacy mobile devices.

New from Alps Electric, the SCHF series is a miniSD card conversion adapter for microSD cards for use in mobile phones, digital cameras and other compact mobile devices.

Of late, there has been an increase in the variety and sises of memory cards fitted into mobile phones and small-format personal audio devices.

In mobile phones for example, if a customer wants to change to a newer model, there is the possibility that the sise of the memory card in the new handset will differ from the current model.

Thus there has been an increasing need for an adapter to enable data transfer between memory cards of different sises.

The SCHF series is a connectible adapter that converts a micro SD card to the sise of a miniSD card.

To ensure safe handling of the memory card, the chassis uses a compound resin rather than a metal frame.

The use of the compound resin prevents short circuits, even if a memory card of a different sise to the adapter were to be mistakenly inserted.

The robust structure is twist-resistant, accomplishing both greater safety and robustness.

Another valuable feature is the use of a half-lock structure, which prevents the inserted microSD card from falling out due to vibration or impact.

The adapter's structure also prevents memory cards from being inserted incorrectly, thus enhancing its user appeal as a reliable and easy-to-use product.

These features make use of the technologies Alps has cultivated over several years for the thin-walled mould processing, simulation engineering techniques etc.

Simulation engineering in particular provided a fluidity analysis of the compound resin, which enabled us to define a resin that would provide the optimum part structure and twist-resistance and to determine the optimum pressure for reliable contact with the terminals.

Accelerated development is being promoted to improve the efficiency of the design.
