Flip type solar junction box

Abstract

The invention relates to a flip type solar junction box, which comprises a shell, an upper cover, a circuit board arranged in the shell, and a heating device connected with the circuit board, wherein the front end edge of the shell is in overturn connection with one edge of the upper cover through hinges; end faces of two side walls of the shell are respectively provided with a left insertion hole and a right insertion hole; the inner side wall of the left insertion hole is provided with a plurality of left convex teeth; the inner side wall of the right insertion hole is provided with a plurality of right convex teeth; the lower surface of the upper cover is provided with a left insertion head corresponding to the left insertion hole and a right insertion head corresponding to the right insertion hole; the inner side faces of the left and right insertion heads are respectively provided with a left rack and a right rack which are matched with the left convex teeth and the right convex teeth; the upper cover is inserted into the left and right insertion holes of the shell through the left and right insertion heads and is locked. The designed flip type solar junction box can provide convenience for replacing devices, and is good in sealing property, waterproof and dustproof.

Description

technical field [0001] The invention relates to the field of solar junction boxes, in particular to a flip-type solar junction box. Background technique [0002] After the crystalline silicon solar cell is packaged, the power of the component (actual power) will be less than the sum of the power of all cells (theoretical power), and this difference is called the power loss of the component package. How to reduce power loss at present is the aspect that many large and medium-sized solar energy factories have been working hard and paying attention to. It is also the focus of the current development of module technology, because it is directly related to the production cost of the factory, and also directly related to the economic benefits of each solar module factory. In fact, the junction box still occupies a high proportion in reducing the power loss of components. According to our company's tests on the samples of many manufacturers in the industry, the current average po...

Problems solved by technology

Assuming that there is only a difference of 0.5W, but converted to the annual production volume, this loss is also quite large, because this loss is the company's net profit. At present, how to reduce the loss of the junction box in the industry is still in the groping stage

[0003] Due to the problem of sealing between the upper cover and the casing in the current junction box, it is easy to cause dust to enter during use and does not have the purpose of waterproofing
