Electric vehicle charging connector adapter nested in an electric vehicle supply equipment
A charging connector adapter is nested within a holster of an electric vehicle supply equipment (EVSE). If the adapter is to be used, the EVSE automatically locks the charging connector to the charging connector adapter and unlocks the charging connector adapter from the holster of the EVSE thereby allowing the charging cable with the charging connector adapter to be removed from the holster and used for connecting the charging connector adapter to an inlet of an electric vehicle. When the charging connector adapter is inserted back into the holster, the EVSE locks the charging connector to the holster and unlocks the charging connector from the charging connector adapter.
