As shown in FIG. 1(a), a lead wire 1 such as a tin-bowed annealed copper wire is cut to a required length. Next, as shown in FIG. 1(b), the central portion of the lead wire 1 is rolled to form a rolled portion 4 at the central portion. As a result of rolling, this rolled portion 4 is naturally wider than other portions of the lead wire 1. Next, as shown in FIG. 1(c), the rolled part 4 has become wider.
A punched portion 5 is formed by punching out the central portion of the sheet. Thereafter, as shown in FIG. 1(d), 7lux 6 is applied to the punched portion 5, and a predetermined fuse alloy 3 is further set. Next, as shown in FIG. 1(e), the fuse alloy 3 is welded by heating. Figure 1(e') is Figure 1(e)
It is a front view seen from the front. Next, as shown in FIG. 1(f), the rolled portion 4 of the lead wire 1 remaining on both side edges of the punched portion 5 is cut. The temperature fuse manufactured in this manner has opposing leads #! as shown in FIG. 1(f). A fuse assembly *3 is welded and installed on the wide part 2 of 1. The temperature fuse of the present invention manufactured in this way is shown in FIGS. 3 and 4 (a).
) As shown in (b), the installation portion of the fuse alloy 3 is covered with a case 7 made of a material such as ceramic, and filled with a sealant 8 made of synthetic resin such as epoxy resin. Here, if the inner diameter of the caser is set to be approximately the same as the width of the wide part 2, when the case 7 is fitted, the wide part 2 will come into contact with the inner surface of the case 7 and centering will be performed. By the way, by welding and installing the fuse alloy 3 between the opposing wide parts 2, the welding area (wetted area)
This increases the tensile strength, and the attractive force when the fuse alloy is melted increases, making it possible to achieve ultra-miniaturization.Also, consistent manufacturing methods from low to high currents are possible, and these factors The electrical characteristics after operation are excellent, but the shape of the opposite part of the wide part 2 that will become the welded part when punching is shaped into a semicircular arc as shown in the attached drawing, or any other concave or convex shape, or If the shape is uneven, the tensile strength is further increased, the welded area (wetted area) is further increased, and the suction force when the fuse alloy 3 is melted is accordingly increased.

By welding the fuse alloy to the punched part and then cutting the rolled portion of the lead wire remaining on both side edges of the punched part, a temperature fuse with the above effects can be manufactured by a simple method. It is extremely easy to weld the fuse alloy, and it is easy to automate the welding of the fuse alloy and the lead wire, making automatic manufacturing equipment inexpensive. It can be mass-produced.
