れている。(Conventional technology) Conventional methods for chemically converting lead wire terminals include:
As shown in FIG. 5, there is a method using a lead wire holder 24 in which a hole 23 into which a large number of lead wires 22 of a lead wire terminal having an aluminum flat portion 21 can be inserted is formed. When the lead wire 22 is inserted into the hole 23 of this holder 24, the welded portion 25 of the lead wire terminal
Since the diameter of the lead wire 22 is larger than that of the hole 23, the lead wire 22 stops at the welded portion 25, and the ends of the flat portions 21 of the lead wire terminals inserted in the same manner thereafter are almost aligned. Then, the inserted lead wire 22 is pressed by the hollowed-out vertical holding surface 26 of the holder 24 with a holding jig 27 equipped with a conductive brush.
This holding jig 27 is connected to the anode of a power source 28, and the cathode is connected to the chemical conversion liquid 30 in the chemical conversion tank 29.

悪い問題点を有していた。 In such an apparatus, since it is necessary to keep the flat part 21 immersed in the chemical conversion liquid 30 constant, the height of the holder 24 can be adjusted using the mounting jig 31 of the holder 24.
This is done by means of a bolt 32 provided in the. However, when such a chemical conversion method is used, since the conductive part of the holding jig 27 that presses the lead wire 22 is a conductive brush, the contact may be incomplete, or a large number of wires may be pressed by the holding jig 27. When doing so, there are problems in that the lead wires 22 may fall off because they are not pressed sufficiently, and that they cannot be worked on in large quantities and have poor workability.

A lead wire terminal consisting of a welded lead wire 4 is inserted so that the lead wire 4 contacts the inner bottom surface of the container 1. A magnetic electrode jig 5 is disposed on the outer bottom surface of the container 1 containing the lead wire terminals in this manner, and the electrode jig 5 is connected to the anode of a power source 6. In this state, the lead wire 4 is attracted and held by the magnetism of the electrode jig 5, and does not fall off even if it is turned upside down.Since the tip of the lead wire 4 is in contact with the inner bottom surface of the container 1, the flat part 3 is also almost completely closed. It can be adjusted to a certain height. The lead wire terminal accommodated in the container 1 in this way is
As shown in the figure, the flat parts 3 are immersed in the chemical liquid 8 in the chemical conversion tank 7, but since the heights of the flat parts 3 are almost the same as described above, they can be immersed in the chemical liquid 8 up to the same position. Since the cathode of the power source 6 is connected to the chemical conversion liquid 8, by turning on the power source 6, it is possible to chemically form the portion of the flat portion 3 etc. immersed in the chemical conversion liquid 8. Incidentally, reference numeral 9 denotes a mounting jig, and the height of immersion into the chemical liquid 8 can be adjusted by means of bolts 10 and the like attached to this jig. For example, if a container contains 750 lead wire terminals,
Figure 3 shows the variation in leakage current and its drop when 110V is applied using lead wire terminals that were attached to a jig and subjected to 150V chemical conversion by placing eight of the jigs in a chemical conversion bath. show.

This figure shows the same leakage current, variation, and drop state as in the example for lead wire terminals.

Alternatively, the same effect can be obtained by using a mixture of magnetic materials. The steam vent 2 provided in the body of the container 1 is not only a hole, but also has a claw 11 formed toward the inner bottom as shown in Fig. 4, or has only a claw provided in addition to the steam vent.

る。[Effects of the Invention] According to the method for chemically forming lead wire terminals for electrolytic capacitors according to the present invention, a large number of lead wire terminals can be efficiently chemically formed, and furthermore, contact with the lead wire can be made completely, so that chemically formed lead wires can be easily formed. It is also possible to obtain terminals with excellent characteristics. In particular, in the present invention, vapor from the surface of the chemical liquid does not accumulate inside the bottomed open container, and corrosion of the lead wire inside the container is prevented. In addition, in the present invention, since the container itself has no magnetism, when the lead wires are inserted inside the container, the ends of the lead wires reach the bottom of the container due to the weight of each lead wire, and the positions of the lead wires are aligned. On the other hand, when taking out the processed lead wire from the container, the lead wire can be ejected from the container by simply turning the container upside down. As a result, it is particularly advantageous when the insertion and ejection of the lead wire into the container is automated.
