Abstract
A photovoltaic junction box is provided, including: a box body; a plurality of conduction terminals received in the box body; and at least one surface-mounted diode mounted on the plurality of conduction terminals. Each surface-mounted diode includes a flat body, at least one anode pin extending outwardly from an edge of the flat body, and a cathode pad located on a bottom of the flat body. The cathode pad of at least one surface-mounted diode mounted on a surface of the conduction terminal has a heat conduction angle γ more than 180 degrees and less than 360 degrees. Since the heat conduction angle is more than 180 degrees, the heat produced by the diode may be rapidly transferred to the conduction terminal in time to avoid deterioration or damage to the diode, improving the heat dissipation rate, and improving the current carrying capacity of the photovoltaic junction box.
