Fiber optic connection system and fiber optic connector
In a fiber optic connection system, an adapter has an expandable wall portion that snaps onto a connector and latches with a latch knob of the connector housing. A lock and an extractor are disposed on the connector housing. During insertion, the extractor is in a forward position as the connector housing is inserted into the adapter. The adapter moves the lock backward relative to the housing and extractor, toward an unlocking position, until the adapter snaps onto the latch knob. Then the lock returns to the locking position to lock the connector to the adapter. To extracts the connector, the extractor is pulled backward. This moves the lock backward to unlock the connector from the adapter. Further pulling unlatches the adapter from the latch knob by expanding the expandable wall portion and extracts the connector.
