During a conjuction two celestial bodies appear near one another in the sky. During a conjuction between two planets or between the moon and a planet both celestial bodies have the same right ascension (they stay on a north-south line in the sky). The shortest apparent distance between two celestial bodies doesn't occur per difinition during the conjuction but short before or after the conjunction.
