Description

DETAILED DESCRIPTION OF THE INVENTION This defense 1; L, 7ft 'fN = I A plurality of tab terminals used for installation are arranged individually [1] and arranged in a jig, and This is a method of instantly forming an oxide film on a plurality of tab terminals arranged using a jig.

Leakage current, which is one of the characteristics of electrolytic condenser, is related to the defects and quality of the oxide film formed on the anode. In the case of aluminum electrolytic capacitors, an oxide film is formed on the anode foil and functions as a condenser.However, if an oxide film is formed on the rolled part of the tab terminal that is anodically connected, the rolled part 1. A leakage current occurs, deteriorating the characteristics of the aluminum electrolytic capacitor and causing -C. Therefore, if a tab terminal is used in which an oxide film is formed by chemically treating the rolled portion and the round bar portion of the tab terminal as necessary, the leakage current can be suppressed.

Here, a tab terminal is illustrated in FIG. The tab end r1 is J, the round bar part 1a, etc. is /1M',
a shi/,=ff1gli 1 b,! :, round bar part 1
a lJ7'Ff73 lead part 1G or 1 buzz. The lead IC is made of tin-plated copper-clad steel wire, half-[11-plated copper-clad steel wire, tin 1--thickel wire 4: or half [■1 plated nickel wire-(゛1゜Such tab terminal 1). Rolling section 11) Method of roughly forming an oxide film on the round bar section 1a as needed. Conventionally, the method of gripping the lead section 1c with a clip and immersing it in a chemical solution to form an oxide film (conventional method) Method 1) or a method (conventional method 2) in which a plurality of tab terminals 1 are immersed in a chemical solution to form an oxide film (conventional method 2). However, conventional method 1 has problems. When the lead part 1G is held between the L clips, the lead part 1c is scratched (1), the plating on the part (A) is peeled off, and natural corrosion is accelerated (3). This has the disadvantage of deteriorating the quality of the lead part 3-1G, and the rubber seal []t4 in the subsequent process is damaged.
It has the disadvantage that it does not pass through Φ, resulting in a failure in KItr-.

According to the iH Mirai method, the chemical solution may leak into the welded area 1 (due to the distance between multiple tab terminals bundled together being too narrow).
1.50 Lead portion IC has a drawback in that reactive current is generated during formation and formation occurs, that is, a good quality oxide film cannot be formed on the rolled portion ib. moreover,
There is a drawback that electrochemical dissolution occurs in the welded portion 1d and the lead portion 1G.

However, in order to improve each of the drawbacks of the conventional method 1.2 such as (e), the present invention arranges a plurality of tab ends r individually and separately, jq, and removes the tab terminals. We provide a mounting jig (made of M construction) that is easy to remove, and use this mounting jig to connect a chemical power supply between the chemical liquid in the jig and the chemical solution. Provided is a method in which a current path is formed from the anchor to the chemical liquid via the tab terminal, and the rolled part of the tab terminal and, if necessary, the round bar part are chemically formed to form a high-quality oxide film. It is something to do.

First, FIG. 2 shows a basic mounting jig 4 according to the present invention. The J-0 mounting jig 2 has a long shape and attaches the lead portion 1C of the tab terminal 1 to form a current path. Mounting plate 2a etc. for contacting the tip of lead part 1C @m2
