Abstract
A bonding device electrically bonds metallic surfaces through serrated metal teeth which embed into each metal surface as a fastener is tightened. A sealing material circumferentially outward and inward from the teeth create an air-tight and water-tight seal around the teeth, protecting the bonding location. The device can have an extended central collar extending axially from the through-hole in the center of the device, which will allow it to be installed in holes, or on a stud without the use of adhesives or other retaining methods.

20. A method of electrically bonding a first frame and a second frame, comprising:
-
a) placing an electrical bonding device between a surface of the first frame and a surface of the second frame, the bonding device comprising a metallic body having an upper surface, a lower surface, an inner perimeter surrounding a hole, an outer perimeter, and a plurality of teeth extending axially from the upper surface and the lower surface between the inner perimeter and the outer perimeter;
an inner seal on the upper surface of the body, located radially inward of the teeth;
an inner seal on the lower surface of the body, located radially inward of the teeth;
an outer seal on the upper surface of the body, located between the teeth and the outer perimeter of the body; and
an outer seal on the lower surface of the body, located between the teeth and the outer perimeter of the body;
the electrical bonding device being placed such that the hole is aligned with a hole in the first frame and a hole in the second frame;b) passing a fastener through the hole in the first frame, the hole in the body of the electrical bonding device, and the hole in the second frame; c) tightening the fastener such that the teeth on the electrical bonding device embed in the surface of the first frame and the surface of the second frame creating an electrical bond therebetween, and the inner seals on the electrical bonding device and the outer seals on the electrical bonding device seal against the surface of the first frame and the surface of the second frame, creating an air-tight and water-tight seal around the electrical bond. - View Dependent Claims (21)
