Problems solved by technology

[0002] In the photovoltaic industry, photovoltaic junction boxes are required to connect solar panels to users. The diodes in the photovoltaic junction box can act as bypass protection when the photovoltaic cells have hot spot effects. Since the junction box may be placed outdoors, in order to prevent Water corrosion of the components in the junction box, the junction box should have a waterproof function, the existing junction ...

Embodiment Construction

[0008] See figure 1 , an improved photovoltaic junction box cover, which includes a junction box cover 1, a sealing ring placement groove 2 is provided on the inner periphery of the junction box cover body 1, and a sealing ring placement groove 2 is provided on the inner periphery of the junction box cover body 1 near the inner side of the sealing ring placement groove. Two reinforcing ribs 3-1, 3-2, 3-3, 3-4, 3-5, 3-6, 3-7,, 3-8.

[0009] In the present invention, since the inner side of the junction box cover is provided with penetrating reinforcing ribs, it effectively prevents the junction box cover from softening and deforming, improves the waterproof performance of the junction box, avoids water corrosion of components in the junction box, and prolongs the wiring life. The service life of the box.

[0010] In this embodiment, two reinforcing ribs are respectively arranged on the inner side of the periphery of the rectangular cover. Of course, the cover can also adopt ot...

Abstract

The invention provides an improved photovoltaic connecting box cover. With the improved photovoltaic connecting box cover, softening and deformation of the connecting box cover are prevented effectively, the waterproof property of the connecting box is improved, water corrosion on elements in the connecting box is avoided, and the service life of the connecting box is prolonged. The improved photovoltaic connecting box cover comprises a connecting box cover body; and the improved photovoltaic connecting box cover is characterized in that the inside of the periphery of the connecting box cover body is provided with penetrating reinforcing ribs.

Description

technical field [0001] The invention relates to the technical field of photovoltaic equipment, in particular to an improved photovoltaic junction box cover. Background technique [0002] In the photovoltaic industry, photovoltaic junction boxes are required to connect solar panels to users. The diodes in the photovoltaic junction box can act as bypass protection when the photovoltaic cells have hot spot effects. Since the junction box may be placed outdoors, in order to prevent Water corrosion of the components in the junction box, the junction box should have a waterproof function, the existing junction box body and the junction box cover use a sealing ring to realize the waterproof function of the junction box, because the junction box cover is usually made of plastic, the wiring The heating of the components in the box will soften and deform the junction box cover, reducing the waterproof performance of the junction box, causing water corrosion of the components in the ju...
