[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-7 , the utility model provides embodiments:
[0028] A photovoltaic assembly wire fixing structure includes an upper disc cover 1, a caulking bracket 2 is fixedly connected to the lower surface of the upper disc cover 1, the caulking bracket 2 is cross-shaped, a connecting column 3 is fixedly connected to the middle of the lower surface of the caulking bracket 2, a lower disc cover 5 is arranged below the connecting column 3, and the connecting column 3 penetrates the center of the lower disc cover 5 and is slidably connected to the lower disc cover 5, and a solar cell 11 is arranged between each two arms of the caulking bracket 2, and the solar cell 11 is located in the interlayer between the upper disc cover 1 and the lower disc cover 5. By clamping the solar cell 11 from the upper and lower sides of the solar cell 11 by the upper disc cover 1 and the lower disc cover 5, the utility model can be connected to the solar cell 11 is fixedly connected, and the lower disc cover 5 is inserted into the connecting column 3, so that the solar cell 11 can be clamped while avoiding mechanical damage to the solar cell 11 by fasteners such as bolts. When the upper disc cover 1 and the lower disc cover 5 clamp the solar cell 11, there will be gaps between the solar cell 11 due to the existence of the connecting column 3. The gap between the solar cell 11 and the solar cell 11 is filled by the caulking bracket 2, which can provide a large amount of supporting surface between the solar cell 11 and the solar cell 11, so as to avoid the solar cell 11 being completely pressed on the center of the caulking bracket 2 to cause damage to the solar cell 11.
[0029] Furthermore, in order to prevent the upper disc cover 1 and the lower disc cover 5 from directly clamping the solar cell 11 and causing wear to the solar cell 11, a buffer pad 4 is provided on the upper surface of the lower disc cover 5 and the lower surface of the solar cell 11. The buffer pad 4 and the lower disc cover 5 are fixedly connected, and the connecting column 3 also passes through the center of the buffer pad 4. In addition to preventing the lower disc cover 5 from direct friction damage to the solar cell 11, the buffer pad 4 can also play a filling role, so that when the upper disc cover 1 and the lower disc cover 5 clamp the solar cell 11 of different thicknesses, the solar cell 11 can be grasped more firmly through the filling of the buffer pad 4.
[0030] Figure 3 Because it is inverted, the lower surface of the lower disc cover 5 is actually fixedly connected with an electric wire box 6, and the electric wire box 6 is also sleeved on the outer surface of the connecting column 3. When the electric wires between the solar cells 11 and the solar cells 11 are connected to each other, the wires can be protected from damage by wind, sun and rain through the shelter provided by the electric wire box 6. A limited hexagonal bolt 7 and a wire coiling column 8 are arranged inside the electric wire box 6. The limited hexagonal bolt 7 and the wire coiling column 8 are fixedly connected. At the same time, the outer surface of the lower half of the connecting column 3 is provided with an external thread, and the inner surface of the wire coiling column 8 is provided with an internal thread, and the inner surface of the limited hexagonal bolt 7 is self-threaded. With threads, the connecting column 3 is connected with the limiting hexagonal bolt 7 through the threaded connection to fix the caulking bracket 2 and the buffer pad 4, the solar cell 11 and the upper disc cover 1 and the buffer pad 4. The function of the limiting hexagonal bolt 7 is to tighten the connection between the upper parts, and the wire winding column 8 provides a winding core. When the wires between the solar cells 11 and the solar cells 11 are still very long after being connected, the excess wires can be wound around the wire winding column 8, which will not cause the interior of the wire box 6 to appear very messy. The bottom end of the wire winding column 8 is slightly larger than the upper section, and its function is to prevent the wires wound around the wire winding column 8 from falling off.
[0031] Figure 3 In the figure, through holes are provided on the four sides of the wire box 6, and the connecting wires of the solar cell 11 are inserted into the interior of the wire box 6 through the through holes for connection. The function of the wire box 6 is to ensure that the wires on the solar cell 11 can enter the wire box 6 while minimizing contact with the outside world, which can better avoid damage to the wires caused by wind, sun and rain.
[0032] Furthermore, in order to protect the wires passing through the side through holes of the wire box 6 from being worn by the wire box 6, a protective wire sleeve 9 is fixedly connected inside each through hole of the wire box 6. Since the protective wire sleeve 9 is soft, the wear rate of the wires can be minimized.
[0033] When the wires are connected in the wire box 6 , in order to close the wire box 6 , a box cover 10 is engaged with the lower opening of the wire box 6 , so that the wire box 6 becomes a closed space that can only contact with the outside world through the protective wire sleeve 9 .
[0034] Working principle: When used Figure 6 and Figure 7 As shown, the utility model is clamped at the diagonal positions of four solar cells 11, at which time the upper disc cover 1 is on the upper surface of the solar cell 11, and the caulking bracket 2 is in the gaps between the four solar cells 11, then the buffer pad 4, the lower disc cover 5 and the wire box 6 are sequentially sleeved on the connecting column 3, and the buffer pad 4, the lower disc cover 5 and the wire box 6 are located on the lower surface of the solar cell 11, and then the limiting hexagonal bolt 7 is connected with the thread of the connecting column 3 to tightly connect the upper disc cover 1, the solar cell 11, the buffer pad 4, the lower disc cover 5 and the wire box 6 to avoid mechanical damage to the solar cell 11 caused by the bolts inserted into the solar cell 11, and then the wires on the solar cell 11 are extended into the wire box 6 through the protective wire sleeve 9 to be connected, and the excess part is wound around the wire coiling column 8, and finally the solar cell 11 is covered to avoid the wires in the wire box 6 from being damaged by wind, rain and sun.
