An adjustable bonding washer for placement between two metal pieces to create an electrical bond between them. The bonding washer has two metallic parts constrained to slide relative to one another along an axis. Each part has oppositely directed teeth that are forcibly embedded into the metal piece
An adjustable bonding washer for placement between two metal pieces to create an electrical bond between them. The bonding washer has two metallic parts constrained to slide relative to one another along an axis. Each part has oppositely directed teeth that are forcibly embedded into the metal pieces to make electrical contact with them when they are rigidly clamped together. Adjustability enables the bonding washer to be mated with metal pieces having a range of widths and profiles, such as the slotted rails used to support arrays of photovoltaic panels.

1. An adjustable bonding washer for making an electrical connection between two or more metal pieces, the bonding washer comprising: an electrically conductive receiving part including a flat body portion with at least two integral flap portions at a first end thereof and forming two or more channel
1. An adjustable bonding washer for making an electrical connection between two or more metal pieces, the bonding washer comprising: an electrically conductive receiving part including a flat body portion with at least two integral flap portions at a first end thereof and forming two or more channels running along a top surface of said flat body portion; andan electrically conductive engaging part including a flat body portion with at least two insertion tabs at a first end thereof and respectively engaging said channels of said receiving part and overlapping said top surface of said flat body portion of said receiving part, wherein a hole of decreasing size is created as said insertion tabs increasingly overlap said flat body portion of said receiving part, whereinsaid receiving part further includes at least one retainer on said top surface of said flat body portion for engaging a first metal piece of the metal pieces and at least one retainer on a bottom surface of said flat body portion for engaging a second metal piece of the metal pieces, andsaid engaging part further includes at least one retainer on said top surface of said flat body portion for engaging said first metal piece and at least one retainer on a bottom surface of said flat body portion for engaging said second metal piece. 2. The adjustable bonding washer recited in claim 1, wherein, one or more of said at least one retainer of said receiving part is located on a second end of said receiving part opposite said first end thereof, andone or more of said at least one retainer of said engaging part is located on a second end of said engaging part opposite said first end thereof. 3. The adjustable bonding washer recited in claim 2, wherein, said at least one retainer on said top surface of said flat body portion and at least one retainer on a bottom surface of said flat body portion of one or more of said receiving and engaging parts include circular teeth extending away from said top and bottom surfaces, respectively, and are directed in opposite directions. 4. The adjustable bonding washer recited in claim 1, wherein, said receiving part further includes an integral alignment tab located at said second end of said receiving part and perpendicular said flat body portion, andsaid engaging part further includes an integral alignment tab located at said second end of said engaging part and perpendicular said flat body portion. 5. The adjustable bonding washer recited in claim 1, wherein each of said receiving and engaging parts further include a notch at the respective first end of said flat body portions and said notches align with each other to create said hole of decreasing size as said insertion tabs increasingly overlap said flat body portion of said receiving part. 6. The adjustable bonding washer recited in claim 1, wherein, said at least one retainer of said receiving part includes two circular teeth projecting away from said flat body portion of said receiving part, each of said circular teeth of said receiving part being formed on an integral ear formed from the material of said receiving part and parallel to said flat body portion thereof, andsaid at least one retainer of said engaging part includes two circular teeth projecting away from said flat body portion of said engaging part, each of said circular teeth of said engaging part being formed on an integral ear formed from the material of said engaging part and parallel to said flat body portion thereof. 7. The adjustable bonding washer recited in claim 1, further comprising a plurality of teeth formed within said channels of said receiving part and a plurality of recesses formed on said insertion tabs, wherein said teeth and said recesses are configured to engage each other when said engaging tabs are inserted into said channels. 8. An adjustable bonding washer for making an electrical connection between two or more metal pieces, the bonding washer comprising: a substantially flat rectangular body made of electrically conductive material,a plurality of first retaining members located on a top surface of said rectangular body and a plurality of second retaining members located on a bottom surface of said rectangular body,at least two tabs located on opposite ends of said rectangular body and being substantially perpendicular to said rectangular body,at least one channel member located on each side of said rectangular body, anda hole in said rectangular body, whereinsaid hole decreases in size as said at least two tabs on opposite ends of said rectangular body are drawn closer together and said hole increases in size as said at least two tabs are drawn farther apart. 9. An adjustable bonding washer for making an electrical connection between two or more metal pieces, the bonding washer comprising: an electrically conductive receiving part including a flat body portion with at least two integral flap portions at a first end thereof and forming two or more channels running along a top surface of said flat body portion;an electrically conductive engaging part including a flat body portion with at least two insertion tabs at a first end thereof and respectively engaging said channels of said receiving part and overlapping said top surface of said flat body portion of said receiving part, wherein a hole of decreasing size is created as said insertion tabs increasingly overlap said flat body portion of said receiving; anda plurality of teeth formed within said channels of said receiving part and a plurality of recesses formed on said insertion tabs, wherein said teeth and said recesses are configured to engage each other when said engaging tabs are inserted into said channels. 10. An adjustable bonding washer for making an electrical connection between two or more metal pieces, the bonding washer comprising: an electrically conductive receiving part including a flat body portion with at least two integral flap portions at a first end thereof and forming two or more channels running along a top surface of said flat body portion; andan electrically conductive engaging part including a flat body portion with at least two insertion tabs at a first end thereof and respectively engaging said channels of said receiving part and overlapping said top surface of said flat body portion of said receiving part, wherein a hole of decreasing size is created as said insertion tabs increasingly overlap said flat body portion of said receiving part, whereinsaid receiving part further includes an integral alignment tab located at said second end of said receiving part and perpendicular said flat body portion, andsaid engaging part further includes an integral alignment tab located at said second end of said engaging part and perpendicular said flat body portion.
