Abstract
The utility model relates to a connection box of a solar energy photovoltaic module, which is arranged on the back surface of a solar energy panel and used for the output of power generated by the module. The connection box of the solar energy photovoltaic module comprises a box body and a bypass diode unit, wherein the bypass diode unit is externally arranged in the box body and connected with the box body. Because the bypass diode unit of the connection box of the solar energy photovoltaic module is externally arranged in the box body, the bypass diode unit is not required to be mounted and fixed in the box body, a contact resistance is reduced when a pin of the bypass diode unit is clamped, and the heat accumulation during the operation of a contact point is reduced; and moreover, heat generated by the bypass diode unit during the operation can be immediately emitted to the natural environment under the natural environment, so that the risks that heat generated during the operation can not be emitted when a bypass diode of the prior box body is internally arranged, and the box body is melted and burnt due to heat accumulation are effectively reduced.
