[0012] For the convenience of welding, the bending terminal portion on the copper column soldering sheet is located directly above the copper column soldering sheet, and the terminal cylinder is transversely arranged.

[0013] For the convenience of manufacturing terminal cylinder, the terminal cylinder is bent from part of bending terminal portion.
