Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a photovoltaic module wiring device. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy technology, plays a crucial role in today's energy structure transformation. A photovoltaic power generation system mainly consists of three parts: solar panels, a controller, and an inverter. These three components require precise wiring connections through junction boxes to ensure the normal operation of the entire system.

[0003] However, in practical applications, the wiring connections at the external ends of photovoltaic junction box components are constantly exposed to the outdoor environment. These connections are not only subject to long-term environmental erosion, such as ultraviolet radiation and wind and rain, but also frequently subjected to wind pull. This long-term mechanical stress makes the wiring connections between the wires and the junction box prone to loosening. Once the connections loosen, it leads to unstable power transmission. Furthermore, most junction box designs on the market do not adequately consider the anti-loosening requirements of complex outdoor environments. The junction boxes themselves lack effective anti-loosening structures and cannot effectively address the loosening of wires caused by external forces during long-term use. This also increases the system's maintenance costs and workload. Installers and maintenance personnel need to regularly check the tightness of the connections, and any problems need to be repaired promptly, which undoubtedly brings many inconveniences to the daily operation and maintenance of photovoltaic power generation systems. To address the shortcomings of existing technologies, this utility model provides a photovoltaic module wiring device to solve the above problems. Utility Model Content

[0028] This application provides a photovoltaic module wiring device, which solves the problem that in practical applications, the wiring positions at the outer end of the photovoltaic junction box module are exposed to the outdoor environment all year round. Long-term mechanical stress makes the wiring connection between the wire and the junction box prone to loosening. The junction box itself lacks an effective anti-loosening structure, which increases the maintenance cost and workload of the system.
