Description
Technical Field
The present invention relates to a lead terminal for an electrolytic capacitor, a method for manufacturing the lead terminal for the electrolytic capacitor, and an electrolytic capacitor.
Background
As is well known, a lead terminal for an electrolytic capacitor includes a connection piece terminal formed of a metal rod such as aluminum and a lead wire connected to one end of the connection piece terminal.
In order to suppress leakage of current, a chemically formed coating is formed on the outer surface of the metal bar of the material of the connection piece terminal by chemical treatment.
The connection piece terminal has a bar-shaped portion on one end side and a flat portion on the other end side.
The flat portion is formed by press working a part of the metal rod into a flat plate shape, and in this case, the chemically formed coating film may be cracked.
Therefore, the connection piece terminal is immersed in the chemical conversion solution to perform the secondary chemical conversion treatment, thereby repairing the crack of the chemical conversion coating.
In this case, since the connection portion or the lead of the connection terminal and the lead may be corroded when the chemical generating solution adheres to the connection portion or the lead, the secondary chemical generating treatment is performed only on a region of the flat portion that is spaced apart from the rod-like portion by a predetermined length or more in the axial direction (hereinafter referred to as "secondary chemical generating region").
[ patent document 1 ] Japanese patent laid-open No. 6-97012
Disclosure of Invention
[ problem to be solved by the invention ]
The region between the secondary chemically-generated region and the rod-shaped portion in the flat portion (hereinafter referred to as "intermediate region") is a region having a large plastic deformation by press working, and therefore cracks are particularly likely to occur in the chemically-generated coating film.
Although the secondary chemical generation treatment is not performed on the intermediate region, when the electrolyte of the capacitor element is a liquid, cracks generated in the chemical generation coating are often repaired by the electrolyte.
However, when the electrolyte is a solid, the cracks are difficult to repair, and current leaks from the cracks, resulting in a decrease in the yield of the electrolytic capacitor.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a lead terminal for an electrolytic capacitor, which can suppress a leak current caused by cracking of a chemical generation coating film and improve the yield of the electrolytic capacitor.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings.
As shown in fig. 1, the lead terminal 1 includes a connection piece terminal 10 and a lead wire 20, the connection piece terminal 10 is formed of a metal rod made of aluminum or the like, and the lead wire 20 is connected to one end of the connection piece terminal 10.
The metal rod is subjected to a chemical generation treatment in advance so that the outer surface is covered with a chemical generation coating (hereinafter, this chemical generation coating is referred to as "1 st chemical generation coating").
The connection piece terminal 10 is formed by pressing the metal bar, and has a bar-shaped portion 11 on one end side and a flat portion 12 on the other end side.
In fig. 2, solid-line hatching applied to the outer peripheral surface of the rod-shaped portion 11 indicates the 1 st chemically-formed coating.
A lead wire 20 is connected to one end of the rod-shaped portion 11 by welding or the like. Lead wire 20 is formed of, for example, a CP wire in which a copper layer is provided on the outer peripheral surface of a steel wire.
The flat portion 12 is formed by press-working a part of the metal bar into a flat plate shape and cutting the outer periphery thereof in the thickness direction. The lead 20 may be connected after the flat portion 12 is formed by pressing a metal rod.
An outer surface of a region (hereinafter, this region is referred to as a "secondary chemical generation region") 121 of the flat portion 12, which is spaced apart from the rod-like portion 11 by a predetermined length L1 or more in the axial direction, is covered with a chemical generation coating (hereinafter, this chemical generation coating is referred to as a "2 nd chemical generation coating"). In fig. 2, the dashed hatching indicates the 2 nd chemical generation film, and the 1 st chemical generation film is formed below (inside) the 2 nd chemical generation film.
In the present embodiment, the rib 13 is formed to extend between the rod-shaped portion 11 and the flat portion 12.
The rib 13 is formed between the end surface of the rod-shaped portion 11 on the flat portion 12 side and one surface of the flat portion 12, and has a substantially semicircular shape in plan view.
The bead 13 is formed in a region 122 (hereinafter, this region is referred to as an "intermediate region") of the flat portion 12 between the rod-like portion 11 and the secondary chemical generation region 121.
The outer surface of the intermediate region 122 is covered with an insulating resin coating. In fig. 2, the insulating resin film is shown by grid hatching, and the 1 st chemically-formed film is formed below (inside) the insulating resin film.
The insulating resin coating is formed by, for example, applying a solution of a thermosetting insulating resin to the intermediate region 122 by a known dispenser and heating and curing the solution by a heating device, but may be formed by another method.
In the present embodiment, the insulating resin coating is made of a thermosetting acrylic resin, but other materials may be used. For example, epoxy resin, silicone resin, acrylic resin, phenol resin, fluorine resin, urea resin, or the like may be used, and UV curable resin may also be used.
The insulating resin coating of the present embodiment has a film thickness of 30 μm, but is not particularly limited as long as it can effectively suppress leakage current by coating the reinforcing ribs 13. For example, the film thickness can be set in the range of 0.1 to 100 μm, and more preferably in the range of 10 to 50 μm.
In addition, the length L1 of the intermediate region 122 (the length in the axial direction of the rod-like portion 11) covered with the insulating resin coating is preferably set in consideration of the manufacturing cost and productivity as follows: l1. ltoreq.L 2/3, where L2 represents the entire length of the flat portion 12 in the same direction.
The electrolytic capacitor of the present invention is manufactured by the following steps.
First, a plurality of metal rods each having an outer surface coated with the 1 st chemical-generating coating film were prepared.
Then, the metal bar is pressed to form the connection piece terminal 10.
Next, the outer surface of the secondary chemically-formed region 121 of the connection piece terminal 10 is coated with a 2 nd chemically-formed coating film.
Then, the outer surface of the intermediate region 122 is coated with an insulating resin coating film.
A pair of leads 20 protruding from an end face of capacitor element 40 are inserted through one of a pair of through holes 51 formed in sealing body 50 (see fig. 4), capacitor element 40 and sealing body 50 are housed in a bottomed cylindrical sealing case 60, the opening end of sealing case 60 is crimped to fix sealing body 50 to the opening end of sealing case 60, and the opening end of sealing case 60 is closed by sealing body 50.
Further, a cylindrical shrink film (not shown) in which a product name, a manufacturer name, and the like are described is fitted around the outer periphery of the package case 60, and the shrink film is heat-shrunk, whereby the electrolytic capacitor 100 is completed.
In the lead terminal 1 of the present invention, since the intermediate region 122 is coated with the insulating resin coating, even if a crack is generated in the 1 st chemical generation coating of the intermediate region 122 at the time of press working of the connection piece terminal 10, leakage of current from the crack can be suppressed, and the yield of the electrolytic capacitor is improved.
In particular, when the lead terminal 1 of the present invention is used for an electrolytic capacitor in which the electrolyte is a solid, the yield is significantly improved as compared with the case of using a conventional lead terminal.
In the present embodiment, the outer periphery of the rod-shaped portion 11 is not covered with an insulating resin coating. Since the rod-shaped portion 11 is inserted into the through hole 51 of the sealing member 50, if the rod-shaped portion 11 is coated with the insulating resin coating, the thickness of the insulating resin coating needs to be controlled.
That is, if the thickness of the insulating resin coating is too large, it is difficult to insert the insulating resin coating into the through hole 51, and conversely, if the thickness of the insulating resin coating is too small, a gap is formed between the insulating resin coating and the through hole 51, and an electrolyte may leak.
When the outer periphery of the rod-shaped portion 11 is not coated with the insulating resin coating, the thickness of the insulating resin coating does not need to be controlled, and thus productivity is improved.
The present invention is not limited to the above embodiments.
For example, in the above embodiment, the insulating resin coating is formed on both the anode foil side lead terminal and the cathode foil side lead terminal, but the insulating resin coating may be formed only on one of the lead terminals.
Further, the insulating resin coating may be formed also on the outer peripheral surface of the rod-shaped portion (the region in fig. 2 where solid-line hatching is applied). In this case, the generation of leakage current from the rod-shaped portion is also reduced, and therefore the yield is further improved.
The shape and number of the ribs are not limited to those shown in the above embodiments.
Further, the present invention can be applied to a lead terminal without a reinforcing rib.
The present invention can also be applied to an electrolytic capacitor in which the electrolyte is a liquid, and also to a hybrid electrolytic capacitor in which the electrolyte is composed of a liquid and a solid.
In addition, various modifications can be made to the above-described embodiment without departing from the scope of the present invention.
