Connector

A connector, comprising:

• first and second connector housings at least partly connectable with each other, the first connector housing comprising a receptacle to which the second connector housing is at least partly fittable, and the second connector housing comprising a biasing member disposed for being elastically compressed by the receptacle as the connector housings are connected and for accumulating a biasing force to urge the connector housings away from each other, and a sealing ring disposed for secure engagement against an inner circumferential surface of the receptacle to hold the connector housings substantially watertight, the sealing ring being mountable in a temporary mount position located before a proper mount position on the second connector housing with respect to an inserting direction of the first connector housing and a moving means provided between the connector housings for moving the sealing ring to a proper mount position as the connector housings are connected, the biasing member being provided behind the sealing ring relative to the inserting direction, and the biasing member being disposed such that portions of the biasing member align with portions of the sealing ring along the inserting direction, the second connector housing being formed to at least partly accommodate terminal fittings, a retainer for locking the terminal fittings being mountable transversely on the second connector housing, a clearance being formed between an inner surface of the sealing ring and an outer surface of the retainer when the sealing ring is in the temporary mount position and when the inner surface of the sealing ring is secured to the second connector housing over substantially an entire circumference, the sealing ring being provided in overlapping relationship with the retainer in the temporary mount position and abutting the biasing member in the temporary mount position, the sealing ring being spaced from the retainer in the proper mount position.
