Patent ID: 8491323

Claim:
A waterproof connector comprising: a first housing having a fit-on part with an outer periphery; a rubber ring fit on the outer periphery of the fit-on part; and a second housing with a hood having an inner space with an open front end that can receive the fit-on part, an inner sealing surface spaced rearward from the open front end, the inner sealing surface being configured for sealing engagement with the rubber ring when the fit-on part of the first housing is fit completely into the hood, a plurality of ribs spaced circumferentially from one another and extending from the inner sealing surface of the hood to the open front end, inner ends of the ribs being substantially flush with the inner sealing surface and air release parts defined between the ribs and extending from the inner sealing surface to the open front end of the hood, the air release parts occupying a larger surface area in the hood than the ribs for accommodating a release of air from the hood as the fit-on part of the first housing approaches a position in the hood where the rubber ring engages the inner sealing surface.
