FLEXIBLE PRINTED CIRCUIT JOINING STRUCTURE, CONCENTRATOR PHOTOVOLTAIC MODULE, AND FLEXIBLE PRINTED CIRCUIT JOINING METHOD

摘要

The present invention comprises: a connection box for connecting to one another an external conductor and an internal circuit of a device; a metal electrode located inside the connection box and whereto the external conductor is joined; and a strip-shaped flexible printed circuit constituting the internal circuit, whereof a terminal portion is joined to the metal electrode. The metal electrode has a joining portion for joining to the terminal portion so as to overlap therewith. In a free and independent state prior to overlapping the terminal portion, the joining portion maintains a gap between opposing surfaces thereof, which is greater than the thickness of the terminal portion (including soldering), and is flexible toward the side of the opposing surfaces when pressed.
