ABSTRACT:
A method of forming a chain of fuse-links made from an electrically conductive metal plate. Each fuse-link P4 has an arc-shaped fusing portion 1 and a couple of terminal portions 4, 4 constituting a pair of wing-shaped members connected to each end of the arc-shaped fusing portion 1. A carrier strap 9 has a plurality of vertical connecting pieces 8 each positioned at fixed intervals for retaining the plurality of fuse-links P4. Each of a plurality of interconnection pieces 7' is connected to the vertical connecting piece 8 at one end and connected to a side edge of specific side one of the couple of terminal portions at the other end. The other end of the interconnection piece 7' is bent so that the end edges of the couple of terminal portions 4, 4 rise above the carrier strap 9.
