摘要:
A plurality of terminal boards (30A, 30B) for electrically interconnecting a plus electrode and a minus electrode of a solar cell module and cables (90) for external connection corresponding to the both electrodes are placed on a base plate (11), and two corresponding terminal boards (30A, 30B) are bridged by a bypass diode (50). The respective terminal boards (30A, 30B) juxtaposed on the top surface of the base plate (11) are collectively supported and fixed by a retaining plate (60). Accordingly, the generation of an undue strain in the bypass diode (50) can be avoided even in the case of fixing the terminal boards (30A, 30B) to the base plate (11) with the terminal boards (30A, 30B) bridged by the bypass diode (50) beforehand.
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 (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).

The terminal box (10) is provided with multiple terminal boards (21), a reverse load bypass diode (22) that is connected to two corresponding terminal boards (21), a primary resin layer (23) that is attached to the diode (22) and covers the area around the diode (22), and a secondary resin layer (41) that is made from a resin different to that of the primary resin layer (23) and is adhered to parts other than the diode (22) and does not cover the area around the diode (22).
摘要:
A terminal box (10) includes terminal plates (90), a base plate (21) for supporting the terminal plates (90) and an outer plate (22) surrounding the base plate (21). The base plate (21) has higher heat resistance than the outer plate (22) and is mounted and fixed to the outer plate (22). The outer plate (22) is formed integrally with pressing pieces (33) for preventing the lifting of the terminal plates (90) from the base plate 21 by being arranged to be able to come into contact with the outer surfaces of the terminal plates (90) as the base plate (21) is mounted.

摘要:
Three bypass diodes (50) each comprised of a principal body (51) with a rectifying function and a connecting piece extending from the principal body is bridged between corresponding two terminal plates (30A, 30B). The principal body (51) is supported by one terminal plate (30A, 30B), whereas the leading end of a connecting pin (52) is connected with the other terminal plate (30A, 30B). One of the bypass diode (50) has a polarity opposite to that of the remaining ones, and one of the terminal plates (30A, 30B) serves as an auxiliary intermediate terminal neither supporting the principal body (51) of the bypass diode (50) nor connected with a cable (90). Since both cable connecting terminals support the principal bodies (51) of the bypass diodes (50), heat generated by the principal bodies (51) can be efficiently radiated from the cable connecting terminals (30A) to the cables (90).
