Further, bonnet and radiating groove are arranged at the bottom of box body.
Further, on the radiating groove louvre is arranged.
Further, louvre is two rows, and the quantity of every row's louvre equates with the quantity of electric conductor, and is positioned at the below of electric conductor.
Further, there are many reinforcements on the surface of lid.
By the reinforcement of box body bottom design radiating groove, louvre and box body, the heat that box body inside has been produced is lost to the external world as early as possible.
Further, the part of the bottom of box body except the through hole that is used to draw package lead all seals.By the structural design of sealing, thereby guarantee that outside each position of terminal box all insulate, can adapt to the photovoltaic modulies of different encapsulation, promptly aluminium foil encapsulates and the plastic film package assembling.
Compare with prior art, the utlity model has following advantage:
1, can effectively reduce the amount of parts of connection cable, can improve work efficiency simultaneously, increase reliability.
2, directly insert pin jack by the diode pin, avoided the bending of diode pin, so can avoid damaging the risk of diode in the installation process.
3, by the introducing of electric conductor, increase area of dissipation, can protect the whole terminal box life-span, and increased bottom radiating groove and louvre, can quicken the exchange of terminal box internal heat.
4,, can solve present aluminium foil encapsulation photovoltaic module insulation and safety problem by the structural design of sealing.
