摘要:
A solar cell panel has a pair of superimposed plates, and one or more solar energy cells sandwiched between the plates. A connector for making electrical connection to an external connection member in use of the panel is mounted on the periphery of the superimposed plates. To achieve a compact and simple construction, one-piece strip metal electrical conductor members have first ends located between the superimposed plates and electrically connected to the solar energy cells and second ends which protrude from the periphery and are held in a housing of the connector. The second ends act as electrical terminals.

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 (40A) of the heat discharging sheet (40) is received by a heat receiving surface (90A) of the solar battery module (90) via a through hole (11B) formed in the base plate (11) and is discharged efficiently from the solar battery module (90).
摘要:
A by-pass diode includes a first lead plate and a second lead plate respectively arranged on the top face and the bottom face of a rectifier laminate and extending therefrom in opposite directions in parallel relation to each other. The first lead plates is made thinner than the second lead plate. The first lead plate includes a rectangular body portion and a head portion extending from one end face of the rectangular body portion and connected to the rectifier laminate. The head portion further includes a reduced neck portion. The first lead plate has slits in the zone adjacent the head and neck portions connected to the rectifier laminate, the slits being notched deeply width-wise, alternately from each longitudinal side of the rectangular body portion. The by-pass diode is incorporated into a terminal housing for solar battery modules. In such a terminal housing, the link portions connecting the rectifier laminate to the lead plates are prevented from delamination, even under severe use conditions.
