Terminal box and a method of providing it

摘要

Terminal plates ( 30 ) are juxtaposed on a base plate ( 11 ) for electrically connecting positive and negative electrodes of a solar battery module ( 90 ) to cables ( 80 ) for external connection. A rectifying device ( 50 ) spans between adjacent terminal plates ( 30 ). Each rectifying device ( 50 ) has a bypass diode ( 52 ) and a metal clip ( 53 ) resiliently holds the bypass diode ( 52 ). A heat discharging sheet (40) is attached to the lower surface of the clip ( 53 ) for discharging heat generated by the bypass diode ( 52 ). Heat discharged from a heat discharging surface ( 40 A) of the heat discharging sheet ( 40 ) is received by a heat receiving surface ( 90 A) of the solar battery module ( 90 ) via a through hole ( 11 B) formed in the base plate ( 11 ) and is discharged efficiently from the solar battery module ( 90 ).
