Abstract
A power coupler includes an input end assembly and an output end assembly separably coupled to the input end assembly. The input end assembly includes an input end base including a slot, a sealing cover arranged at the input end base, an input conductive member arranged at the input end base and connected to an external power supply, and a self-locking structure. The sealing cover is movable between a closing position to cover a slot port of the slot and an opening position to at least partially open the slot port. The self-locking structure is switchable between a locked state to limit the sealing cover from moving towards the opening position and an unlocked state to not limit the sealing cover. The output end assembly includes an output conductive member configured to extend into the slot and be connected to the input conductive member.
