Abstract

(57) [Summary] [Purpose] To provide a structure that facilitates aligning chain lead structures at even intervals during the manufacturing process of solid electrolytic capacitors. [Structure] A metal holder 30 to which one end of the anode lead 2 led out from the capacitor element 1 is fixed is processed, a cut-and-raised part 30a and a hole 30b are provided, and these are combined with another adjacent metal holder 30a of the same shape. Arrange them at even intervals using only the metal holder itself. [Effect] Conventional chemical conversion jigs have slits that require high processing precision, and metal holders had to be inserted into the slits and aligned. Therefore, by implementing the present invention, the slit can be omitted, so the structure of the jig can be simplified, and the alignment of the chain lead structure can be automated.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a chain lead structure used during the manufacturing process of solid electrolytic capacitors, etc. Regarding improvements to the structure of chain leads to facilitate their alignment. It is.

0002

[Conventional technology]

Chain leads traditionally used during the manufacturing process of this kind of solid electrolytic capacitors The structure of the body has the shape shown in Figure 4, and has a large number of capacitor elements. One end of an anode lead 2 led out from 1 is fixed to a metal holder 3. child These must be arranged at equal intervals in order to be processed all at once in the subsequent chemical decomposition process. For this reason, the holder fixing frame 5 of the chemical conversion jig 4 as shown in FIG. Insert the metal holder 3 into the 6 slits cut in and align it. there was.

0003

[Problem that the idea aims to solve]

By the way, in the conventional method of aligning the metal holders 3 described above, the chemical composition disassembly process in the subsequent process is difficult. During the process, the holder fixing frame 5 of the chemical conversion jig 4 is heated due to high temperature and chemical treatment. The machining of the 6 slits, which serve as alignment standards, requires precision and may cause deformation. As the chemical conversion jig 4 is used many times, the metal holder will fit into the slit 6. As it becomes difficult to insert and align the data, it is difficult to automate the process. There was a drawback.

0004

[Means to solve the problem]

In order to solve the above problems, this invention has developed a condenser in the chain lead structure. Adjacent to the metal holder to which one end of the anode lead led out from the sensor element is fixed. The metal holder is provided with cut-and-raised portions and holes that respectively engage with the metal holder.

[0005] In addition, one end of the anode lead led out from the capacitor element is fixed to a metal A rod-shaped spacer is fixed to the holder along the longitudinal direction of the holder.

[0006]

[Effect]

According to the above configuration, the cut-and-raised part provided on the metal holder itself and the hole that engages with it The chain lead is evenly spaced by the spacer fixed to the metal holder. Structures can be arranged sequentially.

[0007]

【Example】

Embodiments of the present invention will be described with reference to the drawings. Figure 1 shows an example of the present invention. 1 is a schematic perspective view of a chain lead structure; FIG. In the figure, 1 is a capacitor element. 2 is an anode lead, 30 is a metal holder, and constitutes a chain lead structure. are doing. In addition, 30a is a cut and raised part provided on the metal holder 30, and 30b is a cut and raised part. This is a hole for inserting the cutting part.

[0008] Next, a method of aligning the chain lead structures will be explained. metal holder 30 In order to align the edges at equal intervals, connect the tips of the cut and raised portions 30a to adjacent metal holes of the same shape. By inserting the chain into the hole 30b of the router 30, a large number of chains can be connected as shown in FIG. The lead structures can be arranged sequentially.

[0009] According to this embodiment, conventionally, processing must be performed on the holder fixing frame of the chemical conversion jig. This eliminates the need for slits, which simplifies the structure of the jig itself. This has the advantage that alignment of the lead structure becomes easier. In addition, the aligned chains The lead structure must be held with an appropriate holding jig to prevent it from coming off. There is.

0010

[Example 2] FIG. 3 is a perspective view of a chain lead structure according to a second embodiment of the present invention. This fruit In this embodiment, in place of the cut and raised portion 30a and the hole 30b of the first embodiment shown in FIG. 1, as shown in FIG. A rod-shaped spacer 31a along the longitudinal direction of the metal holder 31 as shown is attached to the metal holder. Since it is the same as the first embodiment except that it is fixed to the side surface of the case 31a, it is the same as the first embodiment. The same reference numerals are given to the parts, and the explanation thereof will be omitted.

[0011] In this embodiment, machining of the cut and raised portion 30a and hole 30b as shown in FIG. 1 is unnecessary. In addition, the operation of inserting the tip of the cut and raised portion 30a into the hole 30b is unnecessary. The chain lead structures can be easily aligned at predetermined intervals using only the spacer 31a. It has the advantage of being able to In addition, when aligning this chain lead structure, If so, it is necessary to hold them using an appropriate holding jig to prevent them from coming off. .

0012

[Effect of the idea]

As explained above, the chain lead structure according to the present invention has a metal holder itself. Obtain equal spacing using the cut-and-raised parts and spacers fixed to the metal holder. This eliminates the need for slits that require precision machining in chemical conversion jigs, etc., and this makes the treatment easier. The structure of the tool is simplified, making it easy and simple to align the chain lead structure. Therefore, it has the effect of being compatible with automation.
