Charging connector and charging apparatus are provided. The charging connector includes a partition plate including at least one charging interface provided on each side surface of two opposite side surfaces of the partition plate. The at least one charging interface is electrically coupled to a charging interface of a battery to charge the battery. Two lateral plates are respectively pivotally connected to the two opposite side surfaces of the partition plate and respectively rotatable with respect to the partition plate. Outer edges of the two lateral plates, which are away from a pivot joint portion, are configured to move away from or close to the partition plate to expose or cover the two opposite side surfaces of the partition plate to enable the charging connector to be in an open state or a folded state correspondingly.
