[0002] The solar photovoltaic module junction box is one of the important components for outputting solar power. It is usually composed of a box body, a box cover, a bypass diode set in the box body, and a conductive connection mechanism. Among them, the bypass diode in the junction box plays a role in preventing reverse charging from damaging the solar photovoltaic cells.

The photovoltaic junction box glue barrier cover is used to prevent the glue from being overfilled or underfilled when the junction box is manually filled with glue. Currently, some problems often arise when manually filling the module junction box with glue, namely, after the AB glue is overfilled and solidified, the junction box cover cannot be successfully closed or cannot be tightly closed, and the glue overflows and affects the appearance, and the AB glue is underfilled and cannot protect the interior of the junction box.

[0022] The present invention will be described in detail below with reference to the accompanying drawings. What is described here is merely a preferred embodiment of the present invention, and those skilled in the art may conceive of other methods for implementing the present invention based on the preferred embodiment, and such other methods also fall within the scope of the present invention.

[0023] Example

[0024] Please refer to Figure 1 This embodiment provides a photovoltaic junction box glue barrier cover, including a substrate 110, which is arranged in a first direction. A pair of side panels 120 are relatively arranged on both sides of the substrate 110, and the side panels 120 are arranged along a second direction, and the first direction intersects the second direction. When injecting glue, the plane where the substrate 110 is located extends to the interior of the junction box, and the side panels 120 contact the side walls inside the junction box, playing a supporting role for the substrate 110. A glue overflow port 111 is provided on one side of the substrate 110, and a glue injection platform 130 is provided at the position of the glue overflow port 111 on the substrate 110. The glue injection platform 130 is provided with a glue injection port 131, and the glue injection port 131 is connected to the glue overflow port 111, and the glue overflow of the glue overflow port 111 can be observed from the glue injection port 131. A cover body 140 is movably provided on the substrate 110, and the cover body 140 can pass through the glue injection platform 130 to cover the glue overflow port 111. Fill the glue from the glue injection port 131 and observe the position of the glue. When the glue reaches the position level with the bottom of the cover 140, the glue will overflow from the overflow port 111. At this time, move the cover 140 to the position of the overflow port 111 to cover the overflow port 111, separate the excess glue, ensure the appropriate amount of glue, and avoid overfilling or underfilling. The main function of the glue injection station 130 is to separate the excess glue of the glue injection station 130 and the glue required by the junction box itself after filling. It should be noted that in this embodiment, the first direction is perpendicular to the second direction. During the use of the glue isolation cover, the first direction is the horizontal direction and the second direction is the vertical direction.

[0025] The movement of the cover 140 depends on its structural design. The cover 140 is slidably connected to the base 110. Under the action of an external force, the cover 140 slides toward the glue overflow port 111. Specifically, a slide groove is provided on the surface of the base 110, and the cover 140 slides within the slide groove. Ball bearings are provided on both sides of the cover 140, and the balls contact the slide groove. The rolling action of the balls reduces friction between the sides of the cover 140 and the slide groove, reducing the resistance to the sliding of the cover 140 and improving the smoothness of the movement of the cover 140.

[0026] It will be appreciated that in some embodiments, the surface of the base 110 is provided with a plurality of slideways, and the bottom of the cover 140 is provided with balls. The balls cooperate with the slideways to enable the cover 140 to slide along the slideways. In this case, the cover 140 is positioned above the base 110, and the length and width of the cover 140 are not greater than those of the base 110. The cooperation between the balls and the slideways can reduce the sliding resistance of the cover 140 and improve the sliding efficiency of the cover 140.

[0027] Furthermore, Figure 1 As shown, the cover 140 is provided with a shifting block 141, which facilitates manual movement of the cover 140. The shifting block 141 can be designed in an elongated, cylindrical, or spherical shape. In one embodiment of the present application, the shifting block 141 is designed in an elongated shape. The distance between the shifting block 141 and the edge of the cover 140 is greater than the width of the glue overflow port 111 to ensure that the cover 140 smoothly covers the glue overflow port 111 and avoids obstructing the movement of the cover 140.

[0028] In one embodiment of the present application, Figure 1 As shown, the glue injection station 130 is provided with a slot for the cover 140 to pass through. The width and height of the slot are both greater than the width and thickness of the cover 140 to avoid obstruction to the moving cover 140 and improve work efficiency.

[0029] It should be noted that the area of ​​the glue injection port 131 is not less than the area of ​​the glue overflow port 111. On the one hand, this facilitates glue injection by the glue injection equipment. On the other hand, the larger area of ​​the glue injection port 131 provides a better observation field of view, which helps the staff to timely observe the glue overflow from the glue overflow port 111. The glue injection port 131 is arranged directly opposite the glue overflow port 111, which facilitates the observation of the overall situation of the glue overflow port 111.

[0030] In one embodiment of the present application, the peripheral side of the substrate 110 and the side plate 120 are both in contact with the inner wall of the junction box. Figure 1 As shown, the base plate 110 and the side plate 120 form a concave structure as a whole. The entire concave structure needs to fit the inner wall of the junction box to prevent the potting glue from overflowing and contaminating the inner wall of the junction box.

[0031] Furthermore, a lug 121 is provided at the top of the side panel 120. One side of the lug 121 is connected to the side panel 120, and the other side extends outward. The lug 121 can rest on the outside of the junction box when the base panel 110 and side panel 120 are placed inside, providing support. Furthermore, the lug 121 can serve as a gripping or clamping element, making it easier to remove the entire sealant cover after the junction box is filled with glue.

[0032] It is understood that the ear plate 121 and the side plate 120 are perpendicular to each other. When the ear plate 121 is perpendicular to the side plate 120, the ear plate 121 covers a larger area on the outside of the junction box, which can provide better stability for the entire rubber insulation cover. Of course, the angle between the ear plate 121 and the side plate 120 can be acute or obtuse, depending on the shape of the outer contact surface of the junction box.
