Weather resistant flip lid cover with improved sealing arrangement

摘要

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.

主权项

1. A weather resistant cover for an electrical box or connector, comprising:
a flip lid cover including a first seal recess for receiving a first seal, and a second seal engaging surface for engaging a second seal, the flip lid cover further including a hinge for pivotably coupling to a portion of an electrical box or connector; the first seal recess having a first radius that is smaller than a radius of the second seal engaging surface; wherein when the flip lid cover is in a closed configuration the first and second seals are engageable with first and second sealing surfaces, respectively, of the electrical box or connector; and wherein the first seal is a V-ring having a lip portion and a body portion connected to the lip portion, the lip portion positioned to engage the first sealing surface when the flip lid cover is in the closed configuration; and wherein when the flip lid cover is configured in the closed configuration an inner chamber is formed between the V-ring and the second seal.
