[0002] This disclosure is based on and claims preference to co-pending U.S. Provisional Patent Application No. 62 / 896,948, entitled “Mechanical Grounding Clamp,” filed September 6, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to clamps for fixing and joining structures, and more specifically to a mechanical clamp for securing a photovoltaic module frame to a track system while providing an electrical connection between the frame and the track system. Background Technology

[0004] A photovoltaic (PV) array typically consists of multiple PV modules housed within a metal frame and a track system supporting the modules. When installing a PV array, multiple PV modules are assembled onto a larger mounting structure (sometimes called a track or rack structure). The metal frame of each PV module and the structural components that mount the modules (such as the track) are generally made of aluminum, typically anodized for corrosion resistance. Although the PV module frame is directly attached to the track using bolts or clamps, the anodizing process insulates the metal structure, meaning that the frame and track may not be electrically bonded unless measures are taken to electrically bond them.

[0005] As with other power sources, for safety reasons, national or local electrical codes typically require that the metal frame of a photovoltaic module and the metal track to which it is fixed be electrically coupled. The term "electrically coupled" here technically refers to the formation of a conductive path between the metal structures to ensure sufficient electrical continuity between them to safely conduct any current applied to the metal structures.

[0006] For electrical bonding of metal structures, the common industrial practice is to install an individual grounding plate on each of the anodized metal structures, or to install individual grounding washers between the anodized metal structures. The grounding plates are attached to the metal plate frame of the photovoltaic module using threaded stainless steel screws. Because the screws cut into the aluminum, a connection is formed that can maintain electrical bonding over time. However, the thickness of ordinary metal plates is quite thin (e.g., 0.080 inches), and the common screw size is 10-32, meaning the screws are therefore only about 2 inches thick. 1The connection is made using a 2 / 2 thread, which provides a small acceptable surface contact area in terms of mechanical strength and conductivity. Using separate bonding washers between metal structures can provide a larger electrical contact area for improved electrical bonding connections. However, adding grounding plates or separate bonding washers increases the cost of installing photovoltaic arrays, including supply costs and labor costs associated with installing individual bonding components. Summary of the Invention

[0007] This disclosure provides a description of embodiments of a mechanical clamp for assembling a photovoltaic (PV) array and providing electrical bonding between a PV module frame and a PV track system forming part of the PV array.

[0026] This disclosure provides a description of embodiments of mechanical clamps for assembling photovoltaic (PV) arrays and providing electrical bonding between a PV module frame forming part of the PV array and a track system. This specification and the accompanying drawings should be considered illustrative rather than restrictive. Various modifications may be made to this disclosure without departing from its spirit and scope.

[0027] Reference Figure 1 This illustration shows an exemplary embodiment of a mechanical clamp 10 according to the present disclosure, which serves as an end clamp for securing and attaching a PV module frame 100 to a track 110 of a track system. For ease of description, the mechanical clamp 10 may also be referred to herein as a "clamp" in the singular and a "plural clamp". The PV module frame 100 may also be referred herein as a "frame" in the singular and a "plural frame".

[0028] Now refer to Figures 2 to 5This illustration shows an exemplary embodiment of the clamp 10 according to the present disclosure. In this exemplary embodiment, the clamp 10 includes a conductive body 12 having a top side 12a, a bottom side 12b, a first end 12c, a second end 12d, a first side edge 12e, and a second side edge 12f. The body 12 also includes a mounting hole 14 for receiving a mounting fastener 50. The body 12 includes a first pressing wing or arm 16 and a second pressing wing or arm 18. The first pressing arm 16 extends from the first side edge 12e of the body 12, and the second pressing arm 18 extends from the second side edge 12f of the body 12. The pressing arms 16 and 18 may be integrally or integrally formed into the body 12, or the pressing arms 16 and 18 may be separate components fixed to the body 12 using welding, adhesive, or mechanical fasteners.

[0029] Mounting hole 14 can be, for example, a threaded hole, a clearance hole, or a square hole. Using a threaded hole, fastener 50 can be mounted (e.g., in...). Figure 2 A bolt (shown in the diagram) is screwed into a threaded mounting hole 14 to secure the clamp 10 to the frame 100 and the track 110. A clearance hole allows a mounting fastener 50 (e.g., a bolt) to pass through the hole 14, and a nut (not shown) can be attached to the neck of the bolt 50 to secure the clamp 10 to the frame 100 and the track 110. A carriage bolt allows the square neck of the carriage bolt 50 to fit within the square hole 14, and a nut (not shown) can be attached to the threaded portion of the neck of the carriage bolt 50 to secure the clamp 10 to the frame 100 and the track 110. The mounting fastener 50 is preferably made of a conductive material such as steel, stainless steel, or aluminum.

[0030] Continue to refer to Figures 2 to 5 ,like Figure 4 As shown, the first pressing arm 16 and the second pressing arm 18 extend from the respective side edges 12e or 12f at an angle "α" relative to the respective side edges 12e or 12f. The angle "α" can be in the range of about 5 degrees and about 20 degrees, and is preferably about 10 degrees. Using this angle, when the mounting fastener 50 is tightened to secure the frame 100 to the track 110, the pressing arms 16 and 18 can apply pressing force to the frame 100 and / or the track 110. Additionally, when the mounting fastener 50 is tightened to secure the frame 100 to the track 110, at least a portion (e.g., corner edges) of the pressing arms 16 and 18 forms an electrically bonded member. More specifically, as... Figure 8A As shown, the corner edge 16a of the first pressing arm 16 serves as an electrical bonding member capable of cutting or piercing a non-conductive coating 114 on the frame 100, for example, a coating that protects the frame from corrosion. Examples of such non-conductive coatings include oxides, paints, and / or anodized coatings. Similarly, see... Figure 8AThe corner edge 18a of the second pressing arm 18 serves as an electrical bonding member capable of cutting or piercing, for example, the non-conductive coating 114 on the frame 100 that protects the frame from corrosion. Figure 3 As shown, the front edge 16b of the pressing arm 16 and the front edge 18b of the pressing arm 18 can be tapered. Figure 1 and Figure 6 As shown, tapered edges 16b and 18b facilitate the mounting of the clamp 10 into the slot within the frame 100.

[0031] like Figure 5 As shown, the tab 20 extending from the first end 12c or the second end 12d of the body 12 is preferably perpendicular to the longitudinal axis "A" of the body 12. The tab 20 may be integrally or integrally formed into the body 12, or the tab 20 may be a separate component fixed to the first end 12c or the second end 12d of the body 12 using welding, adhesives, or mechanical fasteners. Figure 4 As shown, the bottom surface or wall 20a of the tab 20 may include a flat portion with rounded edges, or as... Figure 4 As shown by the dashed lines, the bottom surface or wall 20a of the tab 20 may include a flat portion with square edges. In another exemplary embodiment, the bottom surface or wall 20a of the tab 20 may end with a pointed tip (not shown). The tab 20 has a length "L" that, during installation, helps to position the clamp 10 relative to the frame 100. The tab 20 also helps to maintain the orientation of the clamp 10 such that the longitudinal axis "A" of the body 12 is substantially parallel to the track 110. The length "L" of the tab 20 may range from about 0.25 inches to about 2.5 inches. The tab 20 also stabilizes the body 12 when the mounting fasteners 50 secure the clamp 10 to the PV module frame 100 and the track 110.

[0032] The body 12, pressing arms 16 and 18, and tab 20 are made of a material that is capable of applying sufficient pressing force to the frame 100 and track 110 to hold the frame 100 in place relative to the track 110, while also being conductive to provide electrical bonding. As a non-limiting example, the body 12, pressing arms 16 and 18, and tab 20 may be made of stainless steel or other conductive steel, aluminum, and / or aluminum alloys.

[0033] Reference Figures 6 to 8 and Figure 8A right Figure 2The installation of the clamp 10 is described below. First, the frame 100 is placed on the track 110 such that the slot 102 in the frame 100 is positioned close to the slot 112 in the track 110. Then, the second end 12d of the body 12 is inserted into the slot 102 of the frame 100. It should be noted that the tab 20 also acts as a stop to prevent the body 12 from passing completely through the slot 102. With the body 12 of the clamp 10 partially located within the slot 102 of the frame 100, the mounting fastener 50 is then passed through the slot 112 in the track 110 and screwed into the hole 14 in the body 12. The mounting fastener 50 is then tightened to secure the frame 100 to the track 110. Figure 8A As shown, when the frame 100 is fixed to the track 110, the corner edge 16A of the first pressing arm 16 cuts or pierces any non-conductive coating 114 on the edge 102a of the slot 102 in the frame 100, causing the metal of the first pressing arm 16 to make electrical contact with the metal of the edge 102a of the slot 102. Similarly, the corner edge 18a of the second pressing arm 18 cuts or pierces any non-conductive coating 114 on the edge 102a of the slot 102 in the frame 100, causing the metal of the second pressing arm 18 to make electrical contact with the metal of the edge 102a of the slot 102. With the clamp 10 in electrical contact with the frame 100, a conductive path exists between the clamp 10 and the frame 100. Additionally, the head of the mounting fastener 50 makes electrical contact with the track 110, creating a conductive path between the track 110 and the mounting fastener 50, and... Figure 7 In the exemplary embodiment shown, a conductive path is created between the clamp 10 and the mounting fastener 50. As a result, a conductive path is created between the frame 100 and the track 110, enabling the frame to electrically engage with the track.

[0034] Now go to Figure 9 This illustrates another exemplary embodiment of the clamp according to the present disclosure. In this exemplary embodiment, the clamp 10 includes a conductive body 12 and a conductive tab 20. The conductive body 12 is the same as the body 12 described above and will not be repeated. Except for the bottom surface or wall 20a of the tab, the tab 20 is substantially the same as the tab described above. In this exemplary embodiment, the bottom surface or wall 20a is shaped to form at least one electrically bonded member 22, which is capable of cutting or piercing a non-conductive coating similar to a non-conductive coating 114 on the track 110. Figure 9 In the exemplary embodiment shown, the bottom surface or wall 20a of the tab 20 is shaped as a concave surface forming two electrically bonded members 22, each of which is capable of cutting or piercing the non-conductive coating on the track 110.

[0035] Reference Figures 10 to 12This illustrates another exemplary embodiment of the clamp according to the present disclosure. In this exemplary embodiment, the clamp 10 includes a conductive body 12 and a conductive tab 20. The conductive body 12 is the same as the body 12 described above and will not be repeated. Except for the bottom surface or wall 20a of the tab, the tab 20 is substantially the same as the tab 20 described above. In this exemplary embodiment, the bottom surface or wall 20a includes one or more holes 24, each of which is configured and sized to receive an electrically coupled member 26 (see [link to documentation]). Figure 11 ) or electrical connection component 28 (see Figure 12 ).exist Figure 11 In the exemplary embodiment shown, the electrical bonding member 26 is a tubular member with a tapered distal end forming a cutting edge 26a capable of cutting or piercing the non-conductive coating on the track 110. The electrical bonding member 26 can be secured, for example, by press fitting within a corresponding hole 24 in the bottom surface or wall 20a of the tab 20 to create a conductive path between the electrical bonding member 26 and the tab 20 of the clamp 10. Figure 12 In the exemplary embodiment shown, the electrical coupling member 28 is a tubular member with a serrated distal end that forms a cutting edge 28a capable of cutting or piercing the non-conductive coating on the track 110. The electrical coupling member 28 can be secured, for example, by press fitting within a corresponding hole 24 in the bottom surface or wall 20a of the tab 20 to create a conductive path between the electrical coupling member 28 and the tab 20 of the clamp 10. When the frame 100 is secured to the track as described above, including the electrical coupling member 26 and / or the electrical coupling member 28 can improve the electrical connectivity between the clamp 10 and the track 110.

[0036] exist Figures 6 to 8 In the exemplary embodiment shown, frame 100 is an end frame of the PV array, and clamp 10 serves as an end clamp that extends from the outside of the frame into a slot 102 of frame 100. Figure 13 and Figure 14 In the exemplary embodiment shown, clamp 10 serves as an intermediate clamp for securing adjacent frames 100a and 100b to track 110. (Refer to...) Figure 13 and Figure 14The installation of the clamp 10, which serves as an intermediate fixture, is described. First, two frames 100a and 100b are placed on the track 110, such that the slots 102 of each of the frames 100 are aligned and positioned close to the slots 112 in the track 110. Then, the second end 12d of the body 12 is inserted into the slot 102 of the first frame 100a and into the slot 102 of the second frame 100b. It should be noted that the tab 20 also acts as a stop to prevent the body 12 from completely passing through the slots 102. With the body 12 of the clamp 10 partially located within the slots 102 of the first frame 100a and the second frame 100b, the mounting fastener 50 is then passed through the slots 112 in the track 110 and screwed into the hole 14 in the body 12. The mounting fastener 50 is then tightened to secure the frames 100a and 100b to the track 110. Similar to... Figure 8A As shown, when frames 100a and 100b are fixed to track 110, the corner edge 16a of the first pressing arm 16 cuts or pierces any non-conductive coating 114 on the edge 102a of the slot 102 of each of frames 100a and 100b, causing the metal of the first pressing arm 16 to make electrical contact with the metal of the edge 102a of each of the slots 102. Similarly, the corner edge 18a of the second pressing arm 18 cuts or pierces any non-conductive coating 114 on the edge 102a of the slots 102 of frames 100a and 100b, causing the metal of the second pressing arm 18 to make electrical contact with the metal of the edge 102a of each of the slots 102. With the clamp 10 in electrical contact with frames 100a and 100b, a conductive path exists between the clamp 10 and the frames. Additionally, the head of the mounting fastener 50 makes electrical contact with the rail 110, creating a conductive path between the rail 110 and the mounting fastener 50. Figure 14 In the exemplary embodiment shown, a conductive path is created between the clamp 10 and the mounting fastener 50. As a result, a conductive path is created between the frames 100a and 100b and the track 110, enabling the frames to electrically engage with the track.
