Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic junction boxes, and in particular to a glue-filled photovoltaic junction box. Background Art

[0002] Solar photovoltaic system, also known as photovoltaic, refers to the facilities that use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of photovoltaic facilities is solar panels, and the semiconductor materials used to generate electricity are mainly: monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride.

[0003] The photovoltaic junction box is a key component in the solar photovoltaic system. Its main function is to effectively connect the direct current generated by the solar panel to the inverter, power grid or other related equipment. The photovoltaic junction box is mainly composed of three parts: box body, cable and connector. The box body includes the bottom (including copper terminals or plastic terminals), box cover, diode, etc. The upper box body and the lower box body of the photovoltaic junction box are sealed by glue injection.

[0004] The diodes in the photovoltaic junction box are mainly used to protect solar panels from being damaged by reverse current at night or on cloudy days. They use unidirectional conductivity and reverse cutoff characteristics to prevent the generation of reverse current, thereby protecting the photovoltaic power generation system. The circuit board inside the photovoltaic junction box is an electrical component that integrates circuit design and material application. It is located on the back of the photovoltaic module. The function of the photovoltaic cable is to lead the current generated by the photovoltaic module from the junction box and transmit it to the external circuit. The choice of cable is usually based on the current size of the module.

[0005] In the process of using the glue-filled photovoltaic junction box, it is usually necessary to install the diode and the circuit board. The existing circuit board is directly installed by bolts, which results in the need for hand-held tools to install and remove the bolts one by one during the installation and removal of the circuit board, which is not convenient for quick installation and removal of the circuit board. At the same time, in the process of installing the photovoltaic cable, the photovoltaic cable is usually directly fixed on one side of the photovoltaic junction box, which is not convenient for subsequent installation and removal of the photovoltaic cable, and is not convenient for replacement of the photovoltaic cable, and is inconvenient to use.
