Abstract
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.
Description
- The invention relates to the assembly of photovoltaic arrays and other apparatus requiring electrical connection between metal parts.
- U.S. Pat. No. 8,092,129 to Wiley, et al., which is incorporated by reference herein in its entirety, discloses a variety of bonding washer configurations for creating an electrical bond between metal pieces that are to be mechanically fastened together, such as photovoltaic panels and their supporting aluminum rails. Many of these bonding washers and their commercial counterparts and variants have oppositely directed teeth designed to penetrate the anodic coatings of the metal pieces when clamped together. Some have features that retain them in position on one metal piece to facilitate assembly with another metal piece. In some embodiments the teeth are positioned to engage the metal pieces near their fastener holes, while in others the teeth are positioned to engage the metal pieces near their outer edges. Typically, these bonding washers are designed to be compatible with specific metal piece profiles and/or widths.
- The adjustable bonding washer of the invention has enhanced versatility afforded by its two relatively movable parts, each of which carries oppositely directed teeth that engage the metal pieces when fastened together. The bonding washer of the invention thus can be mated with metal pieces having a range of widths and profiles and is especially useful when clamping solar panels to slotted support rails, which typically retain sliding nuts in their slots. The invention also covers a method of electrically bonding two metal pieces using such a bonding washer.
- An adjustable bonding washer (assembly) according to the invention thus comprises first and second metallic parts each having at least one pair of oppositely directed external teeth formed thereon, the parts being slidable relative to each other along an axis and substantially constrained from relative off-axis movement by axially extending guide surfaces formed thereon.
- Each part preferably comprises a substantially flat sheet metal body. The guide surfaces preferably comprise two opposite edges of the first part and bent edges at two opposite sides of the second part that lie close to the opposite edges of the first part when the parts are assembled. Each of the bent edges preferably comprises a folded-over marginal body portion defining a channel in which the first part can slide. Each part may have a fastener opening therethrough for accommodating a fastener that would pass between the channels. Each pair of external teeth preferably comprises a pair of substantially aligned, diverging teeth.
- Also preferred is the inclusion of least one protrusion (e.g., an internal tooth) in each channel formed on at least one of the parts and adapted to engage the other part when the parts are assembled. The first part preferably has axially spaced features such as notches engageable by the protrusion, such features and the protrusion being configured to resist axial separation of the parts once they are assembled. Each part may have a bent-out alignment tab at an axial end thereof, the alignment tabs being disposed at opposite ends of the bonding washer when the parts are assembled.
- The method according to the invention of electrically bonding first and second metal pieces comprises the steps of:
-
- (a) providing an adjustable bonding assembly comprising first and second metallic parts slidable relative to each other along an axis, each part having a primary face with at least one integral projecting tooth and an opposite secondary face with at least one integral projecting tooth;
- (b) placing the first part against the first metal piece such that the external tooth/teeth of the primary side contacts the first metal piece;
- (c) sliding the second part toward the first part so that the external tooth/teeth of the primary side of the second part contacts the first metal piece;
- (d) placing the second metal piece against the bonding assembly so that it contacts the tooth/teeth of the secondary side of each part; and
- (e) clamping the metal pieces together with the bonding assembly between them so that the teeth are forcibly embedded into the metal pieces to make electrical contact therewith.

- Referring to
FIGS. 1 and 2 , a bonding washer according to the invention comprises amale part 10 and a female part. 20, both preferably made of sheet stainless steel.Male part 10 comprises aflat body 11 having twointegral ears 12 at one end folded up and back against the body and anintegral alignment tab 13 at the same end bent down perpendicular to the body. The opposite end of the body has an open-ended recess ornotch 14. Each of theears 12 has a raised, hollow,circular tooth 15 extending away from the body. The underside of the body (seeFIG. 2 ) also has two raised, hollow,circular teeth 16 extending away from the body.Teeth -
Female part 20 similarly comprises aflat body 21 having twoears 22 at one end folded up and back against the body and anintegral alignment tab 23 at the same end bent down perpendicular to the body. The opposite end ofbody 21 has an open-ended recess ornotch 24 similar to recess 14 of the male part. Each of theears 22 has a raised, hollowcircular tooth 25 extending away from the body. The underside of the body also has two raised, hollow,circular teeth 26 extending away from the body.Teeth -
Female part 20 also has anintegral flap 27 at each side of thebody 21. Eachflap 27 is folded up and back over the body substantially parallel to but spaced from it, thereby forming a channel in which thebody 11 of male part slides. When mated (seeFIGS. 3 and 4 ), the twonotches -
FIGS. 5 and 6 show how the bonding washer of the invention can be installed on a metal piece, in this case an aluminum rail R for supporting a photovoltaic panel P. The male andfemale parts respective alignment tabs tabs bolt 13, which engages a rail-retained nut N. The exerted clamping force embeds the tips ofteeth body 11 ofmale part 10 and not significantly interfere with the bonding action of the teeth. Nevertheless, it is preferred thatupper teeth flaps 27 prior to any deformation of the flaps. This arrangement is present but not easily seen inFIG. 5 due its scale. The same arrangement is present in all disclosed embodiments and is clearly visible inFIG. 8 . -
FIG. 7 shows one alternate configuration of the female part. In this embodiment, flaps 37 are punched to form rows of integral, downwardly directed (interior)teeth 38 that engage and scrape along the body ofmale part 10 as the parts are telescoped together during installation. This engagement enhances the electrical bond between theparts FIG. 7 shows triangular teeth (visible through triangular punched holes in flaps 37) but they may be of any shape suitable for their intended purpose.Teeth 38 may be raked away from the mating direction to enhance their resistance to separation of the parts. -
FIG. 8 shows another alternate configuration for the female part. In this embodiment,interior scraping teeth 48 are integrally formed on body 41 and project upward toward flaps 47. As with the embodiment ofFIG. 7 , any suitable tooth form and angle is acceptable. Note thatteeth 45 onears 42 project beyondflaps 47, which is the same preferred arrangement for all embodiments. -
FIG. 9 shows an alternate configuration for the male part. In this embodiment, thebody 51 includes rows of recesses ornotches 52 that are sequentially engaged by the teeth of the female part (FIG. 7 orFIG. 8 ) as the parts are telescoped together. This arrangement effectively resists separation of the parts and is especially effective if the teeth on the female part are raked. - While preferred embodiments have been chosen to illustrate the bonding washer of the invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims.
