Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a wiring assembly and a photovoltaic equipment. Background Art

[0002] In the related art, the cables of the photovoltaic junction box are cylindrical, which is not easy to fix, and the cylindrical cables are thick and difficult to bend. At the same time, in the scene of photovoltaic building integration, the cables and junction boxes need to be hidden and installed, and the cylindrical cables bring many inconveniences to the hidden design.

[0003] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of the present invention provides a wiring assembly.

[0006] A second aspect of the utility model provides a photovoltaic device.

[0007] In view of this, the first aspect of the utility model provides a wiring assembly, which is used for photovoltaic equipment, and the wiring assembly includes: a wiring box; a cable, a first end of the cable is connected to the wiring box; and a terminal, connected to the second end of the cable; wherein the cross-section of the cable is flat.

[0008] In this technical solution, a wiring assembly applied to a photovoltaic device is proposed, and the wiring assembly is used to electrically connect at least two components on the photovoltaic device.

[0009] Specifically, the wiring assembly includes a wiring box, a cable and a terminal. A circuit board is arranged in the wiring box. The first end of the cable is fixed on the wiring box and connected to the circuit board in the wiring box. The second end of the cable extends to the outside of the wiring box and is connected to the terminal. The terminal is used in conjunction with the pin. By plugging the terminal into the pin of the corresponding component, the electrical connection between the circuit board and the component can be completed.

[0010] On this basis, the cable is cut through a plane perpendicular to the extension direction of the cable to obtain a cross section of the cable, in which the cable is flat, that is, the width of the cable is greater than the thickness of the cable.

[0011] By setting a flat cable, on the one hand, a wide side and a narrow side can be constructed on the outer contour of the cable. Compared with a cylindrical cable, the wide side can be laid flat on the photovoltaic component more stably and will not roll or become misaligned on the photovoltaic component, thereby solving the technical defect that cylindrical cables are difficult to fix in related technologies.

[0012] On the other hand, compared with cylindrical cables, flat cables are easier to bend in the thickness direction and have a larger bending range, which can provide convenient conditions for cable wiring. They are suitable for scenarios with higher product thickness requirements and scenarios with larger wiring bending ranges.

[0013] On the other hand, flat cables can be arranged in a narrow space, which can reasonably utilize the narrow space in the photovoltaic equipment, thereby providing convenient conditions for the hidden design of the cables and the miniaturization design of the photovoltaic equipment, thereby achieving the technical effect of optimizing the structure of the wiring assembly, improving the practicality of the wiring assembly, and reducing the difficulty of wiring the wiring assembly.

The second end of the cable 120 extends to the outside of the wiring box 110 and is connected to the terminal 130. The terminal 130 is used in conjunction with a pin. By plugging the terminal 130 into the pin of the corresponding component, the electrical connection between the circuit board and the component can be completed.

[0081] On this basis, the cable 120 is cut through a plane perpendicular to the extension direction of the cable 120 to obtain a cross section of the cable 120 , in which the cable 120 is flat, that is, the width of the cable 120 is greater than the thickness of the cable 120 .

[0109] By providing a flat junction box 110, on the one hand, convenient conditions can be provided for plugging in the flat cable 120, and on the other hand, the flat junction box 110 can be arranged in the narrow space inside the photovoltaic device 200 along with the flat cable 120, thereby providing convenient conditions for the hidden design of the junction assembly 100 and the miniaturized design of the photovoltaic device 200, thereby achieving the technical effect of optimizing the structure of the junction assembly 100, improving the practicality of the junction assembly 100, and reducing the difficulty of arranging the junction assembly 100.

[0110] like Figure 4 As shown, in some embodiments of the present invention, optionally, the thickness of the junction box 110 is a second thickness T2, and the range of the second thickness T2 is: greater than or equal to 4 mm and less than or equal to 10 mm.

[0111] In this embodiment, the thickness of the junction box 110 is the second thickness T2, and the width of the junction box 110 is the second width W2. The second width W2 is greater than the second thickness T2, so as to ensure that the junction box 110 is flat.

[0112] On this basis, the second thickness T2 needs to be greater than or equal to 4 mm and less than or equal to 10 mm.

[0113] By limiting the second thickness T2 to be greater than or equal to 4 mm, it is possible to prevent the junction box 110 that is too thin from being unable to be successfully plugged into the cable 120 .

[0114] By limiting the second thickness T2 to be less than or equal to 10 mm, the thickness of the junction box 110 can be compressed on the basis of meeting the plug-in requirements of the cable 120 , so as to facilitate the arrangement of the junction box 110 in the narrow and long space in the photovoltaic device 200 .

[0117] By providing a flat terminal 130, on the one hand, convenient conditions can be provided for plugging in the flat cable 120, and on the other hand, the flat terminal 130 can be arranged in the narrow space inside the photovoltaic device 200 along with the flat cable 120, thereby providing convenient conditions for the hidden design of the wiring assembly 100 and the miniaturized design of the photovoltaic device 200, thereby achieving the technical effect of optimizing the structure of the wiring assembly 100, improving the practicality of the wiring assembly 100, and reducing the difficulty of arranging the wiring assembly 100.

[0119] In this embodiment, the dimension of the terminal 130 in the thickness direction is the third thickness T3, and the dimension of the terminal 130 in the width direction is the third width W3, and the third width W3 is greater than the third thickness T3, so as to ensure that the terminal 130 is flat. At the same time, the third width W3 is greater than the first width W1, and the third thickness T3 is greater than the first thickness T1, so as to ensure that the cable 120 can be inserted into the terminal 130.

[0120] On this basis, the ratio of the third width W3 to the third thickness T3 needs to be greater than or equal to 2 and less than or equal to 10.

[0121] By limiting the ratio of the third width W3 to the third thickness T3 to be greater than or equal to 2, the size proportion of the terminal 130 in the thickness direction can be compressed on the basis that the cross-sectional area of ​​the terminal 130 meets the plug-in requirements of the cable 120, thereby facilitating the arrangement of the terminal 130 in a narrow and long space.

[0122] By limiting the ratio of the third width W3 to the third thickness T3 to be less than or equal to 10, the terminal 130 can be prevented from being too thin, thereby ensuring the structural strength of the terminal 130 and reducing the possibility of damage to the terminal 130 .

[0123] like Figure 4 As shown, in some embodiments of the present invention, optionally, the third thickness T3 is in the range of: greater than or equal to 4 mm, and less than or equal to 12 mm.

[0124] In this embodiment, the third thickness T3 needs to be greater than or equal to 4 mm and less than or equal to 12 mm.

[0125] By limiting the third thickness T3 to be greater than or equal to 4 mm, the terminal 130 can be prevented from being too thin, thereby ensuring the structural strength of the terminal 130 and reducing the possibility of damage to the terminal 130 .

[0126] By limiting the third thickness T3 to be less than or equal to 12 mm, the terminal 130 can be conveniently arranged in a narrow and long space.
