た。(Prior Art) Generally, a fuse connected to a transformer or the like has a structure described in, for example, Japanese Utility Model Application Publication No. 54-124945. This structure is shown in Figures 1 and 2.
As shown in the figure, a linear fuse element 2 is spirally wound several times around the outer periphery of an insulating core material 1 made of aramid paper or the like, terminals 3 and 4 are crimped and connected to both ends of the fuse element 2, and one After connecting a transformer lead wire or the like to the terminal 4 of the fuse element 2, a heat-shrinkable insulating tube 5 is attached to the outer periphery of the fuse element 2, etc. However, with this fuse structure, although the wire diameter of the fuse element 2 does not change due to the action of tension, the surface of the fuse element 2 may be damaged during fuse assembly work or handling. Terminals 3 and 4 fixed to the end of fuse element 2
The fuse element 2 was damaged by the crimping process, and the fuse element 2 was sometimes blown out by the normal current. Furthermore, such fuses are mechanically weak against aging and may break due to transmission of vibrations from other equipment. Furthermore, if the fuse element 2 is bent due to handling of wiring or the like before the insulating tube 5 is attached to the fuse element 2, and the fuse element 2 is broken, there is a danger that the pieces of the fuse element 2 will fly off.

- As described in Publication No. 90356, the fuse element is housed in a tube made of lead or glass,
There is a fuse structure in which a terminal attached to the end of the tube is directly crimped and connected to the end of a fuse element protruding from the tube. However, even with this fuse structure, the fuse element and the terminal are connected by crimp connection as described above, which makes it easy to damage the fuse element.Moreover, since the contact resistance at the connection point is high, it is easy to cause early oxidation deterioration due to heat generation. .
