摘要: PROBLEM TO BE SOLVED: To provide a copper alloy material for a fuse, which is used for electronic parts of automobiles or home electric appliances and excellent in fusing characteristics to an overcurrent and has a function of preventing burnout of devices or parts.
SOLUTION: A Ni-plating layer having a thickness of 0.01 to 20 μm is formed on the surface of a copper alloy substrate; a Sn-plating layer having a thickness of 0.1 to 30 μm is formed thereon; and the substrate is subjected to a reflow treatment or heat treatment to form an alloy layer containing Ni and Sn while eliminating the Ni-plating layer. Hot-dip Sn-plating may be applied in exchange for the Sn-plating and the subsequent reflow treatment or the heat treatment. Thus, the alloy layer 3 containing Ni and Sn, comprising a Ni-Sn alloy or a Ni-Cu-Sn alloy or both of them, is formed on the surface of the copper alloy substrate 1; and a pure Sn layer 4 as the outermost surface layer is formed thereon to obtain a plated copper alloy material for a fuse.

摘要: PROBLEM TO BE SOLVED: To suppress temperature-rising in a rated current and reduce a cut-off current at the time of fusion by maintaining a current-limiting performance. SOLUTION: A linear or belt-like fuse-element 3 is wound around the outer periphery of an inner cylinder 1, and an integrated body of the inner cylinder 1 and the fuse-element 3 is housed in an insulator cylindrical body 6, while an arc extinguishing sand 7 is filled between the outer wall of the inner cylinder 1 and the inner wall of the cylindrical body 6, and both end apertures of the cylindrical body 6 are sealed with terminals 5. The fuse-element 3 has a structure in which on the outer peripheral face of a round wire 10 or belt-like wires 20 composed of high melting point metal materials and metal covering materials 11, 21 composed of low melting point metal materials are covered. As the high melting point metal material, tungsten or molybdenum is used, and as the low melting point material, lead, zinc, tin, cadmium, aluminum, copper, silver, or alloy of these is used.
