Description of the Related Art Usually, as shown in FIGS. 6 and 7, a cartridge type fuse has a tin-containing fuse at the center of a fusible metal conductor a made of copper or a tin-plated metal having a relatively high melting point.

な回路に使用できなくなる問題点がある。Since the cartridge type fuse as described above utilizes the diffusion phenomenon of the low melting point metal chip b into the fusible metal conductor a, it is 110% to 150% of the rated current.
In a relatively low overcurrent region (hereinafter referred to as a low overcurrent region), the amount of heat generated is small and the progress of diffusion is slow, so melting does not occur or it takes a long time to melt.
There is a risk that the protection circuit will be cut off uncertainly. On the other hand, if it is easy to melt in the low overcurrent region, there is a problem that durability against a momentary large current, that is, a rush current is lost, and it cannot be used in a practical circuit.

耐久性が向上する。A fuse according to claim 1 is characterized in that: a fusible metal conductor having a low melting point metal chip held between a pair of electric connecting portions;
Since the fusible metal conductors that do not hold the low-melting metal chips are juxtaposed, when an overcurrent flows through these fusible metal conductors, the low-melting metal conductors that hold the low-melting metal chips As the chip diffusion progresses and the resistance value increases,
The current flows into the fusible metal conductor without the low melting point metal chip, and it is difficult for the current to melt, so that the durability of the circuit against rush current is improved.

宜変更することが可能となる。In a fuse according to a second aspect of the present invention, a plurality of fusible metal conductors arranged in parallel between a pair of electrical connection parts hold low-melting metal chips having different melting points. When the overcurrent flows through the metal conductor, the diffusion rates of the low melting point metal chips are different from each other, and the fusing characteristics can be appropriately changed.

遮断することができる。In the fuse according to the third aspect, the plurality of fusible metal conductors having different widths are arranged in parallel between the pair of electric connection portions, so that the fusible metal conductors are subject to overcurrent. When it flows, the meltable metal conductor with a narrow width diffuses the low melting point metal more quickly, so it melts first, and when the meltable metal conductor with a narrower width melts, the overcurrent causes a wider meltable metal conductor. Since it concentrates on the wire, the meltable metal conductor having a wide width is quickly melted. Therefore, even in the low overcurrent region, all the fusible metal conductors are melted in a very short time, and the circuit can be surely cut off.

し、その抵抗値は１．２５Ωおよび５Ωである。1 is a perspective view of a fuse A showing an embodiment of the present invention. The fuse A is formed by pressing a thin sheet of fusible metal into a shape in which two fusible metal conductors 2 and 2'having different widths are arranged side by side between the terminal fittings 1 and 1 forming a pair of electrical connection parts. Formed and fusible metal conductors 2, 2 '
The low melting point metal chips 3, 3'are provided in the substantially central portions of the
And the low melting point metal chips 3, 3'are held by swaging the swaging pieces 2a, 2a 'formed on both edges of the fusible metal conductors 2, 2'. The ratio of the widths of the fusible metal conductors 2 and 2'is 4: 1 as shown in FIG. 2, and the resistance values thereof are 1.25Ω and 5Ω.
【００１４】一方、従来のヒューズＰを比較例として用
いた。ヒューズＰは、抵抗値１Ωの可溶金属導体１本

せたものである。On the other hand, the conventional fuse P was used as a comparative example. The fuse P is one in which a fusible metal conductor having a resistance value of 1Ω holds a low melting point metal chip of the same quality and quantity as the fuse A.

００００ となり、両者等しくなっている。When a current of 100 A is applied to both of them, the amount of heat generated at the initial stage (time 0 minutes) is calculated from the equation of amount of heat = current 2 × resistance value, and the conventional fuse P has 100 2 × 1 = 10000 fuses. The fuse A of the invention is 100 2 × 1 ÷ [(1 / 1.25) + (1/5)] = 1
It becomes 0000, and both are equal.

を大きくすることが可能となる。When t minutes have passed after energization, the low melting point metal chip diffuses due to heat generation of each fusible metal conductor. At this time, the fusible metal conductor having a narrow width and a high resistance value has a lower melting point metal chip. Diffusion rapidly proceeded, and the resistance value became the following value. Resistance value of fusible metal conductor 2: 1.43Ω Resistance value of fusible metal conductor 2 ′: 10Ω Resistance value of fusible metal conductor of fuse P: 1.1Ω As described above, the initial specific resistance is the same. However, when two parallel circuits are used, the increase in resistance due to diffusion is large, and the overall resistance value can be made larger than in the case of one series circuit.

する時間が短縮され溶断し易くなる。When the heat generation amount at this time is calculated, the conventional fuse P is 100 2 × 1.1 = 11000, and the fuse A of the present invention is 100 2 × 1 ÷ [(1 / 1.43) + (1 / 10)] =
At 12,500, the heat generation amount of the fuse A increases, the time required to reach the melting point is shortened, and the fuse A is more easily blown.

In the above embodiment, two different widths are used.
Although the case where two fusible metal conductors are arranged in parallel has been described, the number of fusible metal conductors is not limited to two, and three or more fusible metal conductors may be provided so that fusing may occur sequentially. Further, instead of integrally forming the terminal metal fitting and the fusible metal conductor, the fusible metal conductors having different widths may be connected to the separately prepared terminal metal fitting.
