Abstract (en)

[origin: WO2019000306A1] A fuse resistor includes an insulative rod, a first winding wire, a second winding wire and a connection wire. The insulative rod has a first end and a second end. The first winding wire wounds the insulative rod from the first end, and one end of the first winding wire is welded on a first cap. The second winding wire wounds the insulative rod from the second end, and one end of the second winding wire is welded on a second cap. The connection wire is disposed between the first winding wire and the second winding wire. The melting point of the connection wire is lower than the melting point of the first winding wire and the second winding wire. The first winding wire and the second winding wire are disconnected from each other, and electrically connected through the connection wire. The fuse resistor further includes a first electrical cover layer electrically connecting the end of the first winding wire to the first cap, and a second electrical cover layer electrically connecting the end of the second winding wire to the second cap, for enhancing fixing of the first winding wire and the second winding wire and increasing anti-surge effect.
