By-pass rectifier element and terminal housing for solar battery modules using said element

摘要

A by-pass diode (11) comprises a first lead plate (19) and a second lead plate (21) respectively arranged on the top face and the bottom face of a rectifier laminate (17) and extending therefrom in parallel along opposite directions. The first lead plates (19) is made thinner than the second lead plate (21). The first lead plate (19) comprises a rectangular body portion (19a) and a head portion (19b) extending from one end face of the rectangular body portion (19a) and connecting to the rectifier laminate (17). The head portion further comprises a constricted neck portion (23). The first lead plate (19) has slits (27) in the zone adjacent the head and neck portions (19b, 23) connecting to the rectifier laminate (17), the slits (27) being notched deeply width-wise, alternately from each longitudinal side of the rectangular body portion (19a). The by-pass diode (11) is then incorporated into a terminal housing for solar battery modules (1). In such a terminal housing (1), the link portions connecting the rectifier laminate (17) to the lead plates (19, 21) are prevented from exfoliation, even under severe use conditions.
