Patent ID: 8330035

Claim:
A terminal box for solar cell modules, the terminal box comprising: a box body; a plurality of terminal boards arranged in said box body for connecting electrodes of the solar cell modules; a plurality of countercurrent prevention diodes located between a pair of adjacent terminal boards of said plurality of terminal boards, said plurality of countercurrent prevention diodes located between said pair of adjacent terminal boards being arranged in parallel to each other, and each of said plurality of countercurrent prevention diodes having a body and a pair of fitting leads, each one of said pair of fitting leads being connected to one of said pair of adjacent terminal boards; and a plurality of heat transfer plates, each of said plurality of heat transfer plates being integral with one of said plurality of terminal boards and made of a same material as said plurality of terminal boards, wherein said bodies of said plurality of countercurrent prevention diodes located between said pair of adjacent terminal boards are in direct surface contact with said heat transfer plates integral with said pair of adjacent terminal boards, and wherein said heat transfer plates integral with said pair of adjacent terminal boards dissipate heat produced in said plurality of countercurrent prevention diodes and equalize temperatures of said plurality of countercurrent prevention diodes.
