  • Patent number: 9828789
    Abstract: A handle assembly includes a handle, a handle seal recess, and a hub engaging portion. A hub has a lock receiving surface and a handle engaging portion. A shaft is receivable within the hub and has first and second ends, the first end engaged with the handle, and the second end rotatable by rotating the grasping portion of the handle. A V-ring is disposed within the handle seal recess and engages the hub to prevent moisture ingress between the handle and the hub. The hub has a seal recess and an X-ring and an O-ring disposed therein to seal against the shaft to prevent moisture ingress between the hub and the shaft. Axial pressure applied to the O-ring by the hub engaging portion of the handle causes the O-ring to press against the X-ring to force at least one lobe of the X-ring against the central portion of the shaft.
    Type: Grant

  • Patent number: 9496696
    Abstract: A weather resistant flip lid cover for an electrical box or connector preferably includes first and second seals. A hinge pivotally couples the flip lid cover to the electrical box or connector. The first and second seals are preferably concentric. When the flip lid cover is in a closed position the first and second seals engage first and second sealing surfaces on the electrical box or connector to form a seal that complies with the requirements of NEMA Type 4, Type 12, and/or IP66. The first seal is preferably a V-ring. The biasing force of the flip lid cover is preferably sufficient to form a weather resistant seal. The seals may form an inner air chamber therebetween so that when the flip lid cover is moved to the closed position a pressure in the inner compartment is increased and presses a lip of the V-ring against the first sealing surface.
