The traditional grounding method is to drill holes in the frame of the photovoltaic module and the mounting rack, and install self-tapping screws to connect wires for grounding. This method has the problems of cumbersome operation and low installation efficiency due to the need for drilling and using self-tapping screws. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a conductive contact piece for a photovoltaic module to solve the above problems existing in the grounding of current photovoltaic modules.
[0004] To achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A conductive contact piece for a photovoltaic module includes a U-shaped elastic piece, a first conductive part and a second conductive part. The U-shaped elastic piece includes a first clamping plate, a second clamping plate and an abutting plate. The first clamping plate is connected to one end of the abutting plate, and the second clamping plate is connected to the other end of the abutting plate. The first clamping plate and the second clamping plate are used for clamping the frame of the photovoltaic module, and the abutting plate is used for abutting against a support frame; the first conductive part is arranged on the first clamping plate, and the second conductive part is arranged on the second clamping plate. Both the first conductive part and the second conductive part are used for scratching the oxide film on the frame of the photovoltaic module to realize the conduction between the frame of the photovoltaic module and the support frame.
[0006] Further, the first conductive part includes a scriber which extends along the first clamping plate towards the second clamping plate, and is used for scratching the oxide film on the frame of the photovoltaic module and abutting against the frame of the photovoltaic module when the frame of the photovoltaic module is clamped between the first clamping plate and the second clamping plate.
[0007] Further, the first clamping plate is punched towards the direction close to the second clamping plate to form the scriber.
[0008] Further, a plurality of scribers are arranged, and the scribers are arranged at intervals along the length direction of the first clamping plate.
[0009] Further, the second conductive part includes a scratching protrusion which is arranged at the edge of the second clamping plate and extends along the second clamping plate towards the first clamping plate, and is used for scratching the oxide film on the frame of the photovoltaic module when the frame of the photovoltaic module is clamped between the first clamping plate and the second clamping plate.
[0010] Furthermore, the abutting plate is arranged in an arc-shaped bend for abutting against the support frame.
[0011] Advantages of the present utility model:
[0012] For the conductive contact piece of the photovoltaic module of the present utility model, the U-shaped elastic piece is used for clamping on the frame of the photovoltaic module. It includes a first clamping plate, a second clamping plate and an abutting plate. The first clamping plate is connected to one end of the abutting plate, and the second clamping plate is connected to the other end of the abutting plate. The frame of the photovoltaic module can be clamped between the first clamping plate and the second clamping plate. After being installed in place, the abutting plate abuts against the cross bar of the support frame. The first conductive part is arranged on the first clamping plate, and the second conductive part is arranged on the second clamping plate. When the U-shaped elastic piece is clamped on the frame of the photovoltaic module, both the first conductive part and the second conductive part can scratch the oxide film on the photovoltaic module and abut against the frame of the photovoltaic module. Thus, after the photovoltaic module is installed in place, the grounding conduction between the photovoltaic module and the support frame can be achieved without punching holes and using self-tapping screws, etc., thereby significantly reducing the complexity of the grounding operation and improving the installation efficiency.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.
[0020] For the conductive contact piece of the photovoltaic module in the embodiments of the present utility model, the convenient grounding installation of the photovoltaic module is realized through the U-shaped elastic piece, the first conductive part and the second conductive part.
[0021] Such as Figure 1 and Figure 2 As shown in the figure, it is a schematic structural diagram of the frame 1 and the support frame of the photovoltaic module 4. An L-shaped plate 11 is provided at the lower end of the frame 1 of the photovoltaic module 4. Corresponding clamping positions are provided on the cross bar 2 of the support frame. The photovoltaic module 4 is clamped into the clamping positions, and the rapid installation of the photovoltaic module 4 can be completed. During the installation process, the conductive contact piece of the photovoltaic module in the embodiment of the present invention is clamped on the L-shaped plate 11 of the frame 1, and the grounding of the photovoltaic module 4 and the support frame can be completed.
[0022] As Figure 3 and Figure 4 shown, the conductive contact piece of the photovoltaic module includes a U-shaped elastic piece 3, a first conductive part and a second conductive part. The U-shaped elastic piece 3 is used for clamping on the frame 1 of the photovoltaic module 4. It includes a first clamping plate 31, a second clamping plate 32 and an abutting plate 33. The first clamping plate 31 is connected to one end of the abutting plate 33, and the second clamping plate 32 is connected to the other end of the abutting plate 33. The frame 1 of the photovoltaic module 4 can be clamped between the first clamping plate 31 and the second clamping plate 32. After being installed in place, the abutting plate 33 abuts against the cross bar 2 of the support frame. The first conductive part is arranged on the first clamping plate 31, and the second conductive part is arranged on the second clamping plate 32. Both the first conductive part and the second conductive part can scratch the oxide film on the photovoltaic module 4 and abut against the frame 1 of the photovoltaic module 4 when the U-shaped elastic piece 3 is clamped on the frame 1 of the photovoltaic module 4. Thus, after the photovoltaic module 4 is installed in place, the grounding conduction between the photovoltaic module 4 and the support frame can be realized without punching and using self-tapping screws, etc., thereby significantly reducing the complexity of the grounding operation and improving the installation efficiency.
[0023] In some embodiments, the first conductive part includes a scriber 34. The scriber 34 extends along the first clamping plate 31 towards the second clamping plate 32, so that it can scratch the oxide film on the frame 1 of the photovoltaic module 4 and abut against the frame 1 of the photovoltaic module 4 when the frame 1 of the photovoltaic module 4 is clamped between the first clamping plate 31 and the second clamping plate 32 to achieve grounding.
[0024] It should be noted that the scriber 34 is formed by punching on the first clamping plate 31 towards the direction close to the second clamping plate 32, so that it can scratch the oxide film on the frame 1 of the photovoltaic module 4.
[0025] In some embodiments, to ensure conductivity, a plurality of scribers 34 are provided, and the scribers 34 are arranged at intervals along the length direction of the first clamping plate 31.
[0026] In some embodiments, the second conductive portion includes a scoring protrusion 35 disposed at the edge of the second clamping plate 32 and extending in a direction from the second clamping plate 32 towards the first clamping plate 31. The scoring protrusion 35 is configured to score the oxide film on the frame 1 of the photovoltaic module 4 when the frame 1 of the photovoltaic module 4 is inserted between the first clamping plate 31 and the second clamping plate 32, so as to achieve grounding.
[0027] As Figure 2 and Figure 4 shown, the abutting plate 33 is curved and bent to more easily abut against the cross bar 2 on the support frame to achieve electrical connection between the photovoltaic module 4 and the support frame.
[0028] Working principle:
[0029] As Figure 1 and Figure 2 shown, during installation, first, the U-shaped elastic piece 3 is inserted into the frame 1 of the photovoltaic module 4. At this time, the L-shaped plate 11 on the frame 1 is located between the first clamping plate 31 and the second clamping plate 32. Meanwhile, during the insertion process, the slicing piece 34 scores one side of the L-shaped plate 11, and the scoring protrusion 35 scores the other side of the L-shaped plate 11. After installation, the abutting plate 33 abuts against the cross bar 2 of the support frame, thereby enabling electrical connection between the photovoltaic module 4 and the support frame. Compared with the existing grounding method, there is no need to drill holes and use self-tapping screws, which can improve the convenience of installation and the installation efficiency.
[0030] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention fall within the scope of protection of the present invention.
