Connector assembly including legacy and extension parts that maintains backward compatibility

摘要

A card-receiving connector includes a legacy connector part and an additional connector part that facilitates plugging in cards having improved functionality while also allowing legacy cards to be plugged in. In one embodiment, the legacy part includes signal, power, and supply contacts required by a legacy card and includes power and supply contacts required by an improved card in an extension part. A legacy card can be connected to the legacy part without interference from the extension part to facilitate backward compatibility with the legacy card.
