Abstract
The utility model relates to a solar cell module conjunction box, which belongs to the technical field of photovoltaic industry. The solar cell module conjunction box comprises a box body, a box cover, a box mouth, a conducting strip, and a diode. A heat-radiating grid is disposed on the box body and is arranged on a base. The conducting strip is disposed on the base. The conducting strip is connected to the diode through resistance welding, and a radiating fin is disposed below the diode. The solar cell module conjunction box is advantageous in that by means of the radiating fin disposed below the diode, heat generated by the diode can be radiated, and thereby the demand of heat radiation can be met; a U-shaped thickening metal aluminum sheet is adopted for heat radiation, the contact between the aluminum sheet and a heat-radiating rubber is full; the temperature of the diode body can be rapidly transferred to the aluminum sheet, and the heat can be evenly radiated through the heat-radiating rubber; normal work of a semiconductor can be ensured, and service lifetime of the product can be prolonged.
