Patent attributes
Weatherproof, while-in-use electrical receptacle cover assemblies include a base with a cover hingedly coupled to the base and one or more adapter plates. The cover hinge is preferably formed by a pair of camming recesses, a pair of mating pins, and a pair of leaf springs. The leaf springs urge the pins into engagement with the camming recesses. The camming recesses guide the pins in a direction perpendicular to the action of the springs. The cover is provided with at least one catch on an edge opposite the hinged coupling to the base and the base is provided with at least one pawl which engages the catch when the cover is closed. The action of the springs and the camming recesses urge the catch into engagement with the pawl which locks the cover closed against unintentional opening.
