Separating type solar assembly junction box

The invention discloses a separating type solar assembly junction box which comprises a junction main box A and a diode sealing box B. The junction main box A comprises a leading-out wire, a buckle, a lower joint, a groove, a leading-in wire, a conductive copper sheet, a screw, structural plastic, a junction main box casing, a plastic boss, a sealing ring and a metal joint. The diode sealing box B comprises a clamping block, a heat radiating fin, an upper joint, a diode, an insulation heat radiating layer, a lower heat conducting plate, an upper heat conducting plate, a sealing box cover, a diode sealing box casing and a circular groove. The diode sealing box is arranged in the groove on the back surface of the junction main box. The conductive copper sheet and the diode are connected by the upper joint and the lower joint. The outer side of the diode sealing box casing is provided with the heat radiating fin. The outer surface of the diode is coated with the insulation heat radiating layer embedded in the ci
