[0002] With the development of society and the improvement of living standards, solar energy has been widely used as a clean energy. Solar photovoltaic technology converts solar radiation energy into electrical energy through a photoelectric conversion device. The photoelectric conversion device usually uses the photovoltaic effect principle of semiconductor devices for photoelectric conversion. After conversion into electrical energy, photovoltaic cables are usually required for transmission. During the laying of photovoltaic cables, the cable connections are easily affected by external rain and sunlight, so protective structures are needed to protect the cable connections.

[0003] However, there are various types of protective structures in the prior art. For example, utility model patent CN216981392U relates to a protective structure for cables for rooftop photovoltaic components. The utility model includes a photovoltaic component body, a second support plate, a first support plate, a protective cover and a screw hole.
