Shutter mechanism for card adapter

摘要

A spring loaded shutter with locking features is used to expose host pins of an adapter to protect the pins from damage and the user from injury. The locking mechanism for the shutter releases when a card is inserted into the host adapter. Engagement of locking pins by the card releases the locking pins and frees the shutter to be pushed backward as the card is connected to the host pins. The shutter is biased in a forward position so that removal of the card from the adapter results in a return of the shutter to its forward locked position where it effectively covers the pins to protect the pins from damage and the user from injury.
