Description

DETAILED DESCRIPTION OF THE INVENTION It is an object of the present invention to provide a method for manufacturing a Kujial-Taka temperature fuse using the Ij+1 beam melting alloy.

Fusible alloy type I todoha fuse is made of wood lead rod 51
0" Axis wheel alliance and one tree lead with 4 out in the opposite direction! 1 - 4 out in the same direction It is roughly divided into 9 wheel types. Axill 41 is an m-shaped qg alloy with both 41jjK same wheel shape 2
Tip of the wooden lead wire! 9L F11 and mechanically interlocked, with a bell-shaped ii in the fusible alloy surround! It has a structure in which a 1-hole kusu warehouse is covered and both openings g of the booth are sealed with sttim material, and compared to the next kujiful oak, the 4-piece structure is made up of multiple reinforcements, making it difficult to manufacture, and is inferior to mass production.

On the other hand, in the case of a 4M@degree heat seal, for example, the one with the 8il stop structure shown in FIG. 1 is common. This is a lead line parallel to the tree +11 f210 point @ circular town name: &1

Even if the JIg alloy 1) is melted, it will not be fused and the sushi will not be made in one batch, so 7 fuses + 4J is formed in 4 pieces in No. f. However, it is difficult to form a thick layer with a thickness of 7 lux (41ti-#), which may cause variations in the lattice pattern, resulting in unstable production characteristics.

Therefore, recently, a type has been put into practical use in which a radial type temperature fuse is sealed against a fusible alloy with goose t1 and the case has a square space for oJ & alloy g. This type of temperature fuse is relatively cheap to manufacture, but because it requires multiple wires and is difficult to manufacture, it has been widely discontinued.

There was a problem that the manufacturing cost was high due to poor productivity.

The present invention is designed to solve the problem of mass production of case-sealed type IIi temperature fuses using fusible alloys, and to solve this problem by using a lead frame that integrates the lead wires of multiple temperature fuses. te1ζ English #L provides the responsibility of the person □.

The present invention is characterized in that the wires in the above lead claim are fixed at the ends of each set of lead wires from multiple companies with ai seven, and the knees are fixedly joined to the ends of each set of lead wires from multiple companies, and the fusible At-
