With the continuous development of domestic and foreign photovoltaic markets, the demand for photovoltaic junction boxes and connectors has increased dramatically. However, the quality of junction boxes and connectors, which are "inconspicuous" in terms of cost ratio and functional role, have been neglected, resulting in frequent failures and accidents of solar photovoltaic power plants and systems. The problems of connectors have gradually emerged, making both buyers and manufacturers pay attention to product quality.

Since photovoltaic systems are exposed to wind, rain, scorching sun and extreme temperature changes for a long time, connectors must be able to adapt to these harsh environments, so they must not only be waterproof, high Flow capacity and high efficiency.

According to reports, the contact resistance of high-quality photovoltaic connectors is very stable, which is mainly due to the electrical connection technology used. Inferior connectors, due to the rough interior and fewer contact points, make the junction box ignite due to high resistance, and then burn the backplane of the component and cause the component to break.
