Terminal box for solar photovoltaic component

Abstract

A terminal box for a solar photovoltaic component belongs to the technical field of the solar photovoltaic component. The terminal box comprises a box body, a group of electrical connecting members and a group of bypass diodes, wherein the box body forms a box cavity, and the group of electrical connecting members and the group of bypass diodes are arranged in the box cavity; the terminal box is characterized in that positioning flanges are formed in a position of the box body, which corresponds to the group of electrical connecting members; the group of electrical connecting members are positioned on the positioning flanges and comprise electrical connecting sheet bodies and bus bar clamping legs; the electrical connecting sheet bodies are positioned on the positioning flanges; the bus bar clamping legs are integrally formed on the electrical connecting sheet bodies; and the bypass diodes are electrically connected with the adjacent electrical connecting sheet bodies. The terminal box has the advantages: the terminal box can lead bus bars of a solar photovoltaic battery to be conveniently and efficiently inserted into and connected with the bus bar clamping legs of the electrical connecting members and has ideal electrical connection reliability, and as a box cover is omitted, the structure is more compact, and a sealing ring for sealing the box cover and the box body also can be omitted.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic modules, and in particular relates to a junction box for solar photovoltaic modules.

AI Technical Summary

Problems solved by technology

Therefore, it increases the difficulty of the electrical connection between the aforementioned bus bar and the electrical connector, and leads to low installation efficiency and difficulty in ensuring the reliable connection between the bus bar and the electrical connector, which affects the use effect

In addition, the junction box for solar photovoltaic modules in the prior art is usually equipped with a box cover, so the structure is complex and the production cost is high. In order to seal the box cover and the box body, a sealing device is usually required between the box cover and the box body. lock up
