[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0032] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0033] The utility model discloses a waterproof wiring structure for photovoltaic equipment, which is mainly used for wiring cables of high-power string photovoltaic equipment, and optimizes the convenience of wiring installation while achieving a waterproof function.

[0034] See also Figures 1 to 4 As shown, the waterproof wiring structure of the photovoltaic equipment includes a box body 1, a wiring board assembly 2 and a box cover plate 3.

[0035] The box body 1 is a waterproof open structure, the box opening can be located at the top of the box body, and an opening 11 is provided on the side wall of the box body 1 for docking the threading plate assembly 2. Figure 2 For example, the opening 11 can be located on the right side wall of the box body 1, and the opening 11 is in a trapezoidal shape with a larger top and a smaller bottom, which is convenient for the insertion and installation of the threading plate assembly 2.

[0036] The threading plate assembly 2 is sealed and inserted into the opening 11. The portion where the threading plate assembly 2 cooperates with the opening 11 is provided with a sealing feature 22. The sealing feature 22 can be a sealing ring, a gasket or other sealing member. Figure 4 As shown, in this application, the sealing feature 22 is a sealing groove formed by the edge of the threading plate assembly 2. The groove is formed by the edges of the threading stop plate 23 and the edges of the threading sealing plate 24. The groove is provided with elastic sealing ribs 25 to form a single-sided seal with the opening 11. The sealing feature 22 uses a notch to ensure the stability of the threading plate assembly 2 after installation, and the rib seal achieves a waterproof function at the opening 11.

[0037] Figure 2 and Figure 3 The specific structure of the threading plate assembly 2 is shown. In the present application, the threading plate assembly 2 includes a threading limit plate 23, a threading sealing plate 24 and at least one elastic sealing rib 25. Among them, the threading limit plate 23 is on the inner side of the opening 11 of the box body 1, and its main function is to limit the threading sealing plate 24 to the position of the opening 11 of the box body 1. The threading sealing plate 24 is arranged on the outside of the opening 11 of the box body 1, and its main function is to provide waterproofing. The threading sealing plate 24 and the threading limit plate 23 can be connected by screws 26, and the above-mentioned sealing feature 22 is formed at the edge so as to be assembled with the opening 11 of the box body 1. The elastic sealing rib 25 is provided on the inner side edge of the threading sealing plate 24 and surrounds the opening 11 of the box body 1. It is compressed under the clamping force of the threading sealing plate 24 and is sealed to the side wall of the box body 1, thereby playing a sealing role.

[0038] Note that in this application, the top surface of the threading plate assembly 2 is not lower than the surface of the box opening of the box body 1, so that the threading plate assembly 2 forms an effective seal with the inner surface of the box cover 3, thereby achieving a waterproof function. In a preferred embodiment, the top surface of the threading plate assembly 2 can be 1mm-3mm higher than the surface of the box opening of the box body 1, so as to form an interference fit at the top surface of the threading plate assembly 2, thereby improving the sealing performance of the box body 1 and the box cover 3 when closed.

[0039] Combine Figure 4 As shown, to facilitate cable threading, the threading plate assembly 2 includes a pagoda head 21 for threading the target cable. The pagoda head 21 can be cut according to the cable diameter to meet the threading requirements of cables of different sizes. At the same time, it seals the outer diameter of the cable through interference fit, thereby achieving a waterproof function. In this application, the pagoda head 21 is set on the threading sealing plate 24. The pagoda head 21 preferably extends toward the outside of the box body 1 to reduce the space occupied in the box and facilitate the cutting operation before threading the cable.

[0040] Still like Figure 1 and Figure 2 As shown, the box cover 3 is pivotally connected to the box body 1, for example, by a pivotal connection such as a shaft or hinge, thereby achieving the opening and closing function. Furthermore, in the closed state, the inner side of the box cover 3 seals against the box opening of the box body 1 and the top surface of the threading plate assembly 2, completely enclosing the interior space of the box body 1 and ensuring normal operation of the built-in electronic components.

[0041] The use process of the above photovoltaic equipment waterproof threading structure is as follows:

[0042] 1. Place the threading limit plate 23 and threading sealing plate 24 on the inner and outer sides of the opening 11 of the box body 1 and fasten them together with screws 26, so that the threading plate assembly 2 forms a seal with the opening 11 of the box body 1;

[0043] 2. Cut the pagoda head 21 according to the diameter of the target cable, and then pass the target cable through the pagoda head 21 and connect it to the electronic components in the box body 1;

[0044] 3. Close the box cover 3 so that the inner surface of the box cover 3 is sealed against the box opening of the box body 1 and the top surface of the threading plate assembly 2.

[0045] In summary, this application optimizes the sealing design and threading operation, thereby achieving good sealing performance while improving the convenience of the threading operation. The overall structure is relatively simple, the material cost is low, and the cost of use is effectively reduced.

[0046] See also Figure 2 As shown, in some embodiments, the threading limit plate 23 is a frame structure with a hollow center, which reduces weight and facilitates cable threading operations.

[0047] In some embodiments, the number of the elastic sealing ribs 25 is no less than two, and the sealing performance at the opening 11 of the box body 1 is improved through multiple sealing reinforcements, thereby achieving a better waterproof effect.

[0048] In some embodiments, there are multiple screws 26 used to connect the wire threading limit plate 23 and the wire threading sealing plate 24. The screws 26 are located on the inner side of the elastic sealing rib 25 and are arranged at intervals along its contour line. While ensuring balanced force, the screws 26 are prevented from penetrating the side wall of the box body 1, thereby reducing the occurrence of leakage points.

[0049] See also Figure 4 As shown, in some embodiments, the threading sealing plate 24 is provided with a support member 27 extending to the lower bottom of the pagoda head 21. The support member 27 is made of metal and is used to support the pagoda head 21 and enhance the connection between the two, so that the pagoda head 21 is stably fixed on the threading sealing plate 24.

[0050] In some embodiments, there are one or more pagoda heads 21; wherein, the sizes of the multiple pagoda heads 21 are the same, thereby meeting the threading requirements of cables of different sizes and improving the compatibility of the waterproof threading structure of the photovoltaic equipment.

[0051] See also Figure 1 and Figure 2 As shown, in some embodiments, a sealing ring 4 is provided on the inner side of the box cover 3, and the sealing ring 4 is used to seal with the box opening of the box body 1 and the top surface of the threading sealing plate 24, thereby improving the sealing performance in the closed state. Figure 2For example, the sealing ring 4 is a frame-shaped sealing ring 4 adapted to the box opening, which can be compressed under pressure to seal with the box opening of the box body 1 and the top surface of the threading sealing plate 24.

[0052] In some embodiments, a flange edge 12 is provided at the box opening of the box body 1. The flange edge 12 can be integrally formed at the top of the box body 1 to increase the contact area at the box opening, thereby better sealing with the sealing ring 4 on the inner side of the box cover plate 3.

[0053] In some embodiments, a pin hole unit 5 is provided between the flange edge 12 and the box cover 3. In the closed state, the pin hole positioning unit can lock the box body 1 and the box cover 3 together to prevent the sealing failure caused by accidental touch leading to the opening of the box cover 3, thereby improving the reliability of the waterproof threading structure of the photovoltaic equipment.

[0054] In addition, the utility model also discloses a photovoltaic device, including the above-mentioned photovoltaic device waterproof threading structure.
