Abstract:
A watertight connector assembly, comprising:a first connector housing;a first terminal fitting mounted in the first connector housing;a second connector housing mateable with the first connector housing;an inertial locking mechanism located on at least one of said connector housings for generating a first connection resistance during mating;a waterproof ring disposed for engagement between the first and second connector housings, the waterproof ring having front and rear projections spaced axially from one another along a mating direction of said first and second connector housings, said front projection providing a second connection resistance during mating of the housings, and the rear projection providing a third connection resistance during the mating of the housings;a second terminal fitting mounted in the second connector housing, the second terminal fitting being disposed for electrical connection with the first terminal fitting in response to the mating of the first and second connector housings and for generating a fourth connection resistance; andwherein the projections of the waterproof ring are disposed such that the second connection resistance generated by the front projection occurs substantially simultaneously with the first connection resistance generated by the inertial locking mechanism, and such that the third connection resistance generated by the rear projection and the fourth connection resistance generated by the terminal fittings do not occur simultaneously and occur after the first and second connection resistances.
