A connector assembly, comprising a connector and a mating connector mating with the connector,

• wherein the connector comprises:
• an insulating body provided with a plurality of first mounting holes extending in a same direction, wherein each first mounting hole of the plurality of first mounting holes has a first hole opening and a second hole opening that are opposite to each other;
• a plurality of first terminals, wherein a first terminal of the plurality of first terminals is detachably inserted into a first mounting hole of the plurality of first mounting holes through a respective first hole opening and is connected to a first cable passing through the first mounting hole from the respective first hole opening;
• a first locking member detachably inserted into the insulating body, wherein relief grooves with a same number as the plurality of first terminals are disposed on the first locking member, the first locking member is able to be located at a pre-mounting position and a final locking position, the relief grooves on the first locking member at the pre-mounting position are opposite to the plurality of first terminals, and the relief grooves on the first locking member at the final locking position are staggered from the plurality of first terminals;
• a first sealing ring secured to a side of the insulating body facing the first hole opening and abutting against the insulating body, wherein the first sealing ring is provided with a plurality of through holes in one-to-one correspondence with a plurality of first cables, and the plurality of first cables pass through the plurality of through holes respectively and abut against the first sealing ring;
• and
• a second sealing ring sleeved outside the insulating body and abutting against the mating connector sleeved outside the insulating body.
