Embodiment
Below, refer to the attached drawing, embodiments of the present invention are illustrated.
As shown in figure 1, lead terminal 1 possesses connection sheet terminal 10 and lead 20, the connection sheet terminal 10 is by metal bar
Formed, the metal bar is made up of aluminium etc., and the lead 20 is connected with one end of the connection sheet terminal 10.
The metal bar has carried out chemical generation processing in advance, so that outer surface (below, will by chemistry generation overlay film
Chemistry generation overlay film is referred to as " the 1st chemistry generation overlay film ") it is coated.
Connection sheet terminal 10 is that side has bar-shaped portion at one end by carrying out punch process to the metal bar to shape
11, and there is plat part 12 in another side.
In Fig. 2, the solid line hachure for putting on the outer peripheral face of bar-shaped portion 11 represents the 1st chemistry generation overlay film.
In one end of bar-shaped portion 11 leaded 20 are connected by welding etc..Lead 20 is for example set by the outer peripheral face in iron wire
The CP lines for being equipped with layers of copper are formed.
Plat part 12 is by the way that a part of punch process of the metal bar is cut into tabular and through-thickness
Its periphery and formed.Furthermore also connecting lead wire 20 after plat part 12 can be formed carrying out punch process to metal bar.
The region being separated by the axial direction with bar-shaped portion 11 more than specific length L1 in plat part 12 is (below, by this
Region is referred to as " secondary chemical formation zone ") 121 outer surface by chemistry generation overlay film (it is following, the chemistry is generated into overlay film and claimed
For " the 2nd chemistry generation overlay film ") it is coated.In Fig. 2, dotted line hachure represents the 2nd chemistry generation overlay film, and (inner side) is formed thereunder
There is the 1st chemistry generation overlay film.
In the present embodiment, formed with across the reinforcement 13 between bar-shaped portion 11 and plat part 12.
Reinforcement 13 is formed between the end face of the side of plat part 12 in bar-shaped portion 11 and the one side of plat part 12, in vertical view
Substantially semicircle shape.
Reinforcement 13 is formed at the region 122 between the bar-shaped portion 11 in plat part 12 and secondary chemical formation zone 121
In (following, the region is referred to as into " intermediate region ").
The outer surface of the intermediate region 122 is coated to by insulative resin overlay film.In Fig. 2, clathrate hachure represents insulating properties
Resin coating, (inner side) is formed with the 1st chemistry generation overlay film thereunder.
Insulative resin overlay film is, for example, by the solution coating of heat cured insulation resin by using known spot printing machine
In intermediate region 122 and carry out heating using heater and harden it and formed, but can also be formed by other method.
In the present embodiment, the material of insulative resin overlay film is thermosetting acrylic resin, but could be used that other
Material.For example, it can consolidate for epoxy resin, silicones, acrylic resin, phenolic resin, fluororesin, carbamide resin etc., or UV
The property changed resin.
The thickness of the insulative resin overlay film of present embodiment is 30 μm, but as long as being that can be coated to reinforcement 13 and effective
Suppress the thickness of leakage current, be just not particularly limited.For example, thickness can be set in the range of 0.1~100 μm, it is more excellent
Set in the range of being selected in 10~50 μm.
In addition, on the length L1 of intermediate region 122 that is coated to by insulative resin overlay film (along the axis side of bar-shaped portion 11
To length), it is contemplated that manufacturing cost and productivity ratio, preferably set as follows：By the phase Tongfang of plat part 12
When upward total length is set to L2, L1≤L2/3.
The electrolytic capacitor of the present invention is through the following steps that to manufacture.
First, prepare more outer surfaces and the coated metal bar of overlay film is generated by the 1st chemistry.
Then, punch process is carried out to the metal bar and shapes connection sheet terminal 10.
Then, overlay film is generated to be coated to the appearance of the secondary chemical formation zone 121 of connection sheet terminal 10 using the 2nd chemistry
Face.
Then, the outer surface of intermediate region 122 is coated to using insulative resin overlay film.
The lead terminal 1 so manufactured is separately mounted to the anode foils and negative electrode of the raw material as capacitor element
On paper tinsel, and as being as shown in Figure 3 subject to anode foils 41 and Cathode Foil 42 to be separated with the state of barrier film 43 between them
Winding, form capacitor element 40.Then, solid electrolytic is formed between anode foils 41 and Cathode Foil 42 by known method
Matter layer (not shown).
The a pair of lead wires 20 protruded from the end face of capacitor element 40 is inserted through on seal body 50 (with reference to figure 4) and formed
A pair of through holes 51 in either one, capacitor element 40 and seal body 50 are accommodated in the encapsulating shell 60 of bottomed tube, it is right
The openend of encapsulating shell 60 collapse processing and seal body 50 is fixed on to the openend of encapsulating shell 60, the opening of encapsulating shell 60
End is sealed body 50 and closed.
And then the cylindric shrink film (not shown) for recording ProductName, manufacturer's name etc. is enclosed on encapsulating shell 60
Periphery simultaneously shrinks the shrink film thermal, and thus, electrolytic capacitor 100 is completed.
In the lead terminal 1 of the present invention, because intermediate region 122 is coated to by insulative resin overlay film, therefore, even if even
The 1st chemistry generation overlay film of intermediate region 122 produces cracking during the punch process of blade terminal 10, can also suppress electric current from the tortoise
Leaked out in splitting, so the yield of electrolytic capacitor improves.
It is conventional with using especially when using the lead terminal 1 of the present invention to electrolyte for the electrolytic capacitor of solid
The situation of lead terminal compare, yield significantly improves.
Furthermore in the present embodiment, the periphery of bar-shaped portion 11 is not coated to by insulative resin overlay film.Due to bar-shaped portion 11
The through hole 51 of seal body 50 is inserted into, therefore, if bar-shaped portion 11 is coated to by insulative resin overlay film, is needed to insulating properties tree
The thickness of fat overlay film is managed.
That is, if the reason is that the thickness of insulative resin overlay film is excessive, it is difficult to be inserted into through hole 51, in turn, if
The thickness of insulative resin overlay film is too small, then gap can be produced between insulative resin overlay film and through hole 51, so as to produce electrolysis
The anxiety of matter leakage.
In the case of coated not by insulative resin overlay film in the periphery of bar-shaped portion 11, it is not necessary to which this insulative resin covers
The management of the thickness of film, therefore productivity ratio improves.
Furthermore the present invention is not limited to above-mentioned embodiment.
It is the side of lead terminal two of lead terminal in anode foils side and Cathode Foil side for example, in the above-described embodiment
Formed with insulative resin overlay film, but insulative resin overlay film can be also formed only on any lead terminal.
In addition, also it can also form insulative resin in the outer peripheral face (region that solid line hachure is applied with Fig. 2) of bar-shaped portion
Overlay film.In this case, the generation of the leakage current from bar-shaped portion is also reduced, therefore yield further improves.
In addition, the shape and number of reinforcement are not limited to the content shown in above-mentioned embodiment.
In addition, the present invention can also apply to the lead terminal of no reinforcement.
In addition, the present invention can also apply to electrolyte be liquid electrolytic capacitor, also, can also apply to electrolyte by
The mixed type electrolytic capacitor that liquid and solid are formed.
In addition, various changes can be implemented to above-mentioned embodiment without departing from the spirit and scope of the invention.
