AI Technical Summary

Problems solved by technology

When the solar junction box is working, the diodes generate a lot of heat. If the heat cannot be dissipated in time, it will directly affect the performance of the solar junction box.
In addition, the working environment of the solar junction box is relatively harsh, and the sealing performance is also extremely high.
However, the heat dissipation and sealing performance of the existing solar junction boxes cannot meet the requirements

Embodiment Construction

[0033] See figure 1 and figure 2 , The solar junction box described in this embodiment includes: a box cover 1 and a terminal board 2 , cables 3 and line cards 4 . The terminal board 2 is clamped and fixed in the box cover 1 as the back plate of the box cover 1, which makes assembly more convenient. A cavity for filling silica gel is formed between the box cover 1 and the terminal board 2. When the cavity of the box cover 1 is filled with silica gel, the terminal board 2 can be well sealed and protected. One end of the cable 3 is crimped on the terminal board 2 inside the box cover 1, and the other end extends out of the box cover 1 and is provided with a connector 6 for connecting other required components.

[0034] See Figure 4 and Figure 5 The terminal board 2 is integrally packaged by four copper terminals 21 arranged side by side and three diode units connected to the adjacent terminals 21 through an epoxy resin molding compound packaging process. The terminal boa...

Abstract

The invention relates to a solar conjunction box, comprising a box cover, a terminal board and a line card. The terminal board is integrated in a plastic package mode by a plurality of terminals arranged side by side and diode units connecting adjacent terminals; two terminals located on the outmost side are used for connecting cables; the box cover is internally provided with cable slots used for accommodating cables; one end of each cable slot extends into the edge of the box cover; the line card is fixedly connected in the cable slots through ultrasonic bonding, and is located on the edge of the box cover; the cables are clamped between the line card and the box cover; joints between the cables and the terminals are in the cable slots; the cable slots are used for filling silica gel. The solar conjunction box is convenient to assemble, and has sound thermal diffusivity and sealing performance.

Description

technical field [0001] The invention relates to a solar junction box of a solar photovoltaic cell, belonging to the technical field of photovoltaics. Background technique [0002] The solar junction box is a connector between the solar cell array composed of solar cell components and the solar charging control device, providing users with a combined connection scheme for solar cell panels. A general solar junction box is composed of a base, a box cover and terminals located between the base and the box cover, and diodes are arranged between adjacent terminals. When the solar junction box is working, the diodes generate a lot of heat. If the heat cannot be dissipated in time, it will directly affect the performance of the solar junction box. In addition, the working environment of solar junction boxes is relatively harsh, and the requirements for sealing are extremely high. However, the heat dissipation and sealing performance of the existing solar junction boxes cannot mee...
