Novel solar photovoltaic junction box

Abstract

The invention relates to a novel solar photovoltaic junction box which comprises a box base and a box cover covered on the box base, wherein the box base is provided with a photovoltaic assembly; the box cover comprises an enclosure frame which is enclosed into a closed loop; the enclosure frame is provided with a skirt edge for smearing glue; the upper end of the enclosure frame is hollow and is a hollow end; the lower end of the enclosure frame is provided with a containing groove with a downward opening; the containing groove and the box base form a containing cavity together; the box base is clamped with one end of a bus bar so as to form a clamping end; the box base is connected with one end of a cable so as to form a cable end; the clamping end extends out of the containing groove; a second box cover is covered on the upper end of the hollow end; the box base is provided with an injection hole; and the injection hole is communicated with the outer part and the inner part of the containing cavity. According to the invention, glue can be poured through the injection hole, the junction box after glue pouring is beneficial to the heat radiation of a bypass diode, the power of the junction box and the circulated current are increased, and also the structure arrangement is reasonable, and the glue pouring amount is reasonable; and additionally, an insulation wall also greatly increases the safety of the junction box.

Description

(1) Technical field [0001] The invention relates to a solar photovoltaic junction box. (2) Background technology [0002] The solar photovoltaic junction box will generate a lot of heat when it is working. Due to the limitation of heat dissipation performance, it also limits the maximum current it can withstand. In the prior art, the box body is empty, that is, the photovoltaic module is It dissipates heat through the air, so the cooling effect is poor. In addition, the junction box in the prior art has a relatively large box bottom. During installation, the bottom surface of the box bottom is glued and glued to the photovoltaic panel, which wastes resources. (3) Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a photovoltaic junction box that can self-fill glue and improve heat dissipation performance. [0004] The technical scheme that the present invention solves its technical pro...
