The present invention relates to a solar junction box for a crystalline module, which comprises: a rear case (10) having a plurality of heat emitting through-holes and a rectangular window (10b); a metal heat radiation plate (20) in which a bypass diode (11) is embedded and which is fixated by being inserted into a case groove (21); a stainless compression clip (30) which fixates a ribbon by being hung at a hinge pin (31) installed in the rear case (10) and inserted into an upper end portion of the metal heat radiation plate (20); and a front case having an integral grid structure (41) on the surface coupled to the rear case (10). The present invention has excellent contact resistance compared to other product, as the stainless compression clip presses a bus bar or a ribbon of the module, can improve productivity due to reduced workforce required for the operation and shortened time required for the operation process, as a ribbon terminal of a solar light power generation module is connected and fixated to a connector of the junction box only by inserting a heat radiation plate frame coupled with an inner heat radiation plate into an outer case, and is capable of stably supplying electricity due to increased power generation efficiency by preventing the power generation efficiency from being lowered due to heat with efficient cooling of heat generated from a plurality of bypass diodes when generating power. In addition, the present invention allows the assembly operation to be simply performed by forming a cable fixture capable of inserting and fixating a cable to the outer case and has an excellent waterproof capability and durability even if an impact is applied to the case by making the outside of the outer case with an integral grid structure. |
