Patent ID: 7723609

Claim:
A terminal box for solar battery module, comprising: a box main body accommodating at least three terminal plates arranged side by side inside, cable connecting terminals, which are two of the respective terminal plates and connected with cables for extracting electromotive forces from a solar battery module, intermediate connecting terminal(s) formed by the remaining one(s) of the respective terminal plates excluding the cable connecting terminals, and at least two bypass rectifying elements at the time of a reverse load, each including a principal body with a rectifying function based on a cathode and anode junction and supported on one of the two adjacent terminal plates, and a connecting piece connected with the principal body and extending toward the other terminal plate to bridge the two terminal plates, wherein at least one of the respective rectifying elements has a polarity opposite to that of the remaining rectifying element(s) and one of the intermediate connecting terminals serves as an auxiliary intermediate terminal supporting no principal body of the rectifying element, whereby each of the both cable connecting terminals supports the principal body of the rectifying element.
