    摘要: The present invention provides a delayed-fusion fuse by which its predetermined durability can be reliably ensured, and its stable pre-arcing time-current characteristics can be obtained, even when a current exceeding the steady-state current such as a motor lock current frequently flows in the fuse. The delayed-fusion fuse includes a pair of electric connecting sections formed on both sides of a fusible section having a narrow fusing portion made of an electrically conductive metal. Also, the delayed-fusion fuse includes a metallic chip made of low fusing point metal for absorbing heat generated in the fusible section, and a covering and adhering section for holding the metallic chip on the fusible section. A thin metallic layer forms a solid solution with the low fusing point metal, where the solid solution requires an energy of formation which is higher than that of the formation of a solid solution made of the electrically conductive metal and the low fusing point metal. This thin metallic layer is interposed between a surface of the covering and adhering section and a surface of the low fusing point metallic chip. Specifically, the thin metallic layer is provided on a surface of the fusible section in the form of a plating layer.

    摘要: A chain of fuse-links is 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.
