。Conventional technology The conventional terminal caulking method for electrolytic capacitors is the fifth method.
As shown in the figure and FIG.
The rubber plate 9a side is inserted into the phenolic resin laminate 9 on which the straight rivet 8 has been pasted, and the washer 6 is inserted into the tip of the straight rivet 8 that has passed through, and the tip of the straight rivet 8 is pressed with a caulking tool (not shown) to buckle it. By doing so, the terminal 3 with the straight rivet 8 is attached to the rubber plate 9.
It was caulked to a phenolic resin laminate 9 to which a was pasted.

め、気密性に不安があるという問題点を有していた。C. Problem to be Solved by the Invention When the straight rivet 8 is caulked with a caulking tool to the phenolic resin laminate 9 to which the rubber plate 9a is pasted, the axial circumference of the lower neck portion of the straight rivet 8 as shown in FIG. The surface buckles in the radial direction, and the insertion hole 9C of the phenolic resin laminate 9b to which the rubber plate 9a is attached is closed, but since the electrolytic capacitor is filled with electrolyte,
It is necessary to maintain sufficient airtightness of the insertion hole 9c. In this case, if the amount of buckling of the straight rivet 8 is increased by increasing the caulking force, the degree of sealing of the insertion hole 9C will improve, but the buckling force against the phenolic resin plate 9b will exceed the breaking stress of the phenolic resin plate 9b. Therefore, there is a possibility that cracks may occur in the phenol resin plate 9b. As described above, in the conventional caulking method, due to the elastic force of the rubber plate 9a itself and the straight shape of the rivet 8, the degree of adhesion to the rubber plate 9a due to buckling is small, and as a result, the straight rivet 8 and the rubber plate 9a Since it is not possible to ensure a complete seal with the insertion hole 9C of the phenolic resin laminate 9 to which the phenol resin laminate 9 is pasted, there is a problem in that there is concern about airtightness.

When the tip of the small diameter portion 4C of the stepped rivet 4 is pressed by the tapered pressing die 7 and the lower die 7a provided on the opposite side, the shaft diameter of the small diameter portion 4C of the stepped rivet 4 first becomes the large diameter. It buckles to the same diameter as the portion 4a, fills the gap S shown in FIG. 3, and comes into close contact with the insertion hole 5c of the phenolic resin plate 5b. Subsequently, the large diameter portion 4a buckles in the radial direction and bites strongly into the rubber of the black rubber plate 5a, and the stepped rivet 4 is tightened to the surface of the washer 6 with the head 4d.
is formed, whereby the terminal 3 is caulked to the phenolic resin laminate 5 to which the rubber plate 5a is attached.

漏れることは無い。When the terminal 3 is caulked using the above process steps, there is no fear that the small diameter portion 4c and the large diameter portion 4a of the stepped rivet 4 will bite into the phenolic resin plate 5b and cause cracks, and the large diameter portion 4a is buckled and strongly bites only into the black rubber plate 5a, and in this case, the amount of biting is greater than the increase in volume by adding the large diameter part 4a to the stepped rivet 4, and therefore By such reliable and stable caulking, the rubber plate 5a
Since the insertion hole 5c of the phenolic resin laminate 5 to which the capacitor is pasted is completely sealed, the electrolyte inside the capacitor body 2 will not leak.

Effects of the Invention As is clear from the description of the above embodiments, the terminal caulking method for an electrolytic capacitor according to the present invention buckles a stepped rivet with a large diameter portion formed below the neck of the rivet. Since the part is cut only into the rubber of the phenolic resin laminate to which the rubber plate is pasted, it is possible to prevent damage such as cracking of the phenol resin plate, and to reduce the amount of biting into the rubber of the large diameter part. becomes larger, and as a result,
The insertion holes in the phenolic resin laminate covered with rubber plates are completely sealed, improving their airtightness, and this reliable and stable caulking process significantly improves the quality of electrolytic capacitors. It is something that can be done.
