Solar photovoltaic junction box

The invention discloses a solar photovoltaic junction box. The solar photovoltaic junction box comprises a bottom plate, a box body arranged on the bottom plate and a cover plate arranged on the box body; a copper sheet is arranged in the box body; a plurality of diodes are arranged on the copper sheet; a fixing block matched with the copper sheet is arranged in the box body; a wiring port is formed in the side wall of the box body; diode pins are welded to a copper plate; the bottom plate and the box body are both made of heat-resistant materials; a plurality of through grooves are formed inthe bottom plate; and a cooling pipe is laid on the bottom plate. Through a diode welding mode and the high-temperature-resistant material, the high-temperature-resistant performance of the junction box is improved, the junction box is prevented from being damaged under a high-temperature working condition, and the service life of the junction box is prolonged. 本发明公开了一种太阳能光伏接线盒，包括底板、设于所述底板上的盒体及设于所述盒体上的盖板，所述盒体内设有铜片，所述铜片上设有
