What’s the construction of China PV Junction Box?

  China PV Junction Box generally made of the junction box lid, box bodies, terminals, diode, cable, connectors, several major components.

The functions of each part:Shell to have a strong anti-aging, anti-UV; meet the harsh environmental conditions of outdoor use requirements; Self-locking function to make connections more convenient, secure; Should be designed to be waterproof seal, science insulation against electric shock protection, with better security; Terminal installation should be strong, and the convergence with good weldability. Diode is divided into: anti-recoil bypass diode and diode. The main function of the diode is a single wizard-pass function. Bypass diodes: a major role to prevent the components of the hot spot effect.

Hot spot effect: When the components in use are no objects block some cells will be treated as consumption of other light load generated by the components of solar energy. Shaded solar cell chip temperature rising at this time may have a fever, which is the hot spot effect. If a foreign body causing the cells to block local cells do not work, the local cell temperature rise, heat will eventually lead to cell burn.
