US Patent 9276346 Gasketless flip lid for a flanged power inlet receptacle

A power inlet box suitable for outdoor or external use is configured in such a manner so as to prevent moisture from entering the power inlet enclosure. A hinged lid assembly is installable directly on the top face of a flanged power inlet enclosure to provide a face seal therewith. The hinged lid assembly has a cover and a base that form a tongue-and-groove seal, thus providing a first line of defense from moisture or other contaminants entering the inlet. As a second line of defense, a tapered stopper is provided on the inside of the cover to provide a stopper seal. A lateral seal is provided at the hinge point of the hinged lid assembly to prevent moisture from entering the hinge area where a tongue-and-groove seal is not present.
