Description of the Invention (i) Technical Field The present invention relates to a method for manufacturing a wound plastic film capacitor, and more specifically to a plurality of rolled plastic films A manufacturing method of a roll-type plastic film capacitor which does not need to be impregnated with epoxy resin or the like. Such a wound plastic film capacitor is mainly used for a high-voltage generating power source of a Braun tube (cathode ray tube). BACKGROUND ART In the past, "wound plastic film capacitors (hereinafter referred to as" capacitor J ") have been For its voltage resistance, most of the capacitors are connected in series to the inside of the capacitor. Figure 7 shows an example of this. The electrode layer 3 formed by vacuum evaporation inside the plastic film 1 is kept at a certain distance. One side is respectively arranged in the longitudinal direction of the film in an insulated state. These electrode layers 3 constitute an arrangement opposite to two electrode layers 4 which are also formed adjacent to each other on the other plastic film Γ "from the plastic film 1 or 1 'two The electrode layer at the end pulls out the lead wire 8. By winding such plastic films la and lb at the same time, a wound plastic film capacitor is made. Fig. 8 shows the equal compensation circuit of the capacitor shown in Fig. 7. The capacitor elements Cl, C2, ..., C7, and C8 connected in series are connected, and VI, V2, ..., V7, and V8 divided by the voltage Vs applied between the lead wires 8 are added to the capacitor elements, Cl, C2, ... C7, C8. In a capacitor element When the voltage Vs is applied, the capacitor element cannot withstand its high voltage, and although explosion or damage may occur, the voltage Vs can be divided into a plurality of capacitor elements in this way to improve the voltage resistance of the capacitor. However, it is used for this purpose. This kind of capacitor's plastic film (hereinafter referred to as the "medium" only) has a high voltage resistance. Although it is hoped that the paper size existing in the film will apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) I ^ 1 ϋ ft nn. ^ · N ϋ n 1 ^ 4 * · n · 1 I Φ (Please read the notes on the back before filling out this page) 4 A: B: 5. Description of the invention (2 ) Insulation defects such as air bubbles do not exist. However, it is difficult to completely eliminate insulation defects when making a film. So 'clamp the bipolar unpatterned plastic film without the electrode layer between the plastic films formed on the electrode layer, and by overlapping these films, it can compensate for the insulation defect caused by the air bubbles and the like inside the film. Reduced withstand voltage. Fig. 9 shows an example of this, "between the plastic films 丨 and 丨 forming electrode layers, sandwiching two plastics 5 and 5, without patterns. In this case, as long as the number of plastic films 5 without a pattern between the electrode layers is large, it can compensate for more reduced withstand voltage due to insulation defects. The number of plastic films 5 with no pattern sandwiched between the plastic films la and lb forming the electrode layer is three to three, which is more appropriate. The wound (ie, wound) film is impregnated with liquid epoxy resin, which is impregnated with liquid epoxy resin. This impregnation step is also known as vacuum impregnation. By expelling the air existing between the electrodes, it can replace the epoxy resin with excellent voltage resistance, which can suppress the tiny gaps between the films and exist in the electrical field on the electrode layer. Ineffective discharges that occur in the small gaps of strong parts (high-voltage boundary parts) (hereinafter, such cases are referred to as "voids"). -Printed by the Shelley Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, but the conventional winding type film capacitors, especially the high-voltage winding type film capacitors in which high voltage is also applied, are all a plurality of plastic films after winding In order to completely impregnate the epoxy resin, it is necessary to immerse the wound film in a high vacuum state and immerse it in the epoxy resin in a state where the viscosity of the epoxy resin is low. Therefore, the step of immersing the wound film in the epoxy resin becomes a great problem in terms of improving the productivity of the capacitor. In addition, this paper size applies the Chinese Family Standard (CNS) A4 specification (2) 0 * 297 mm. Printed by the Shellfish Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 44280 5 A7 B7 V. Description of the invention (3) The wettability of the wound film epoxy resin is generally impregnated with a heated capacitor in the epoxy resin, but because of the heat that accelerates the ring-opening polymerization of the epoxy resin, the epoxy resin will increase the snapper, and epoxy can be used. The resin has a short time, and as a result, there is a problem of so-called high material cost. The present invention is made to solve the above-mentioned problems. The purpose of the present invention is to provide a plurality of plastic films that have been wound up without being impregnated with epoxy resin and the like. A method of manufacturing a wound plastic film capacitor in which an ineffective discharge occurs from time to time can improve productivity, reduce material costs, and improve voltage resistance and humidity resistance. SUMMARY OF THE INVENTION The present invention includes: a first metallized film la, which is formed by laminating a heat-adhesive resin layer 6 on the surface of a plastic film 1, and a plurality of electrode layers 3 insulated from each other in the longitudinal direction; The dielectric film 2a is formed by laminating a heat-adhesive resin layer 6 only on the surface of the plastic film 5. The second metallized film lb is formed by laminating a heat-adhesive resin layer 6 on the surface of the plastic film 2. The plurality of electrode layers 4 insulated from each other are formed in the longitudinal direction; the second dielectric film 2b is a heat-adhesive resin layer 6 laminated only on the surface of the plastic film 5; it includes the following steps: a winding step, the first step 1 dielectric film 2a is sandwiched between the first metallized film ia and the second metallized film 1b, and the second metallized film 1b is sandwiched between the first dielectric film 2a and the second dielectric film 2b. In addition, each electrode layer 3 of the first metallization film 1a is formed on the second metallization film 1b, two electrode layers adjacent to each other in the length direction. 4 This paper size applies to the national standard 511 (CNS) A4 (210 x 297).

Description of the invention (4) Winding in the overlapped state to form a wound end film; and a heat bonding step for heating the wound end film to bond the heat-adhesive resin layers 6 to each other. 1 between all of the metallized film 1a, the first dielectric film 2a, the second metallized film 1b, and the second dielectric film 2b. In the present invention, since the heat-adhesive resin layer 6 is formed only on the surface sides of all the plastic films, when the heat-adhesive resin is shrunk by cooling after heating, the shrinkage of each plastic film is small, and the wound plural The plastic film does not need to be wetted with epoxy resin, and can effectively suppress invalid discharge. In addition, it is needless to say that the same effect can be obtained even if the surface is exchanged with the inside. In order to make the shrinkage as small as possible, it is preferable that the absolute value of the difference between the thicknesses of the metallized films 1a, 1b and the dielectric films 2a, 2b is 3 m or less. In particular, when the thermal adhesion temperature of the thermal adhesive resin layer laminated on the surface of the metallized film is different from the thermal adhesion temperature of the thermal adhesive resin layer laminated on the surface of the dielectric film, It can more effectively prevent the adhesion of each film from becoming incomplete. The temperature difference is preferably at least 10 degrees Celsius. As long as the maximum surface roughness Rmax of each film is 0.5 micrometers or more and 4.0 micrometers, it can sufficiently withstand the load at high temperatures, and even after repeated charge and discharge, it does not reduce the electrostatic capacity, and can obtain stable capacitor characteristics.

In addition, in this request, the direction above all the drawings is on the surface side, and the direction below the circle is on the inside side. The detailed description of the invention is as follows Describe the invention in detail. (Winding step) As shown in the first circle, in the present invention, first, the first metallized film la and the first dielectric rhenium film 2b are sequentially wound in an overlapping state. The first metallized film ia is a heat-absorbable resin layer 6 on the surface layer. On the one hand, a plurality of electrode layers 3 which are mutually insulated inside are composed of a plastic film 1 formed in the vertical direction. Similarly, the second metallized film 1b is also laminated with a heat-adhesive resin layer 6 on the surface. On the one hand, a plurality of electrode layers 4 insulated from each other on the surface are made of a plastic film 1 formed in the longitudinal direction. Among the films la to 2b, the electrode layer 4a from the longitudinal end of the second metallized film lb is preferably electrically connected to the two wires. In FIG. 1, although two wires 8 are pulled out from the electrode layer 4a at the end of the second metallized film 1b, the two wires 8 may be pulled out from the electrode layer 3a at the longitudinal end of the first metallized film 1a.

Description of the invention (6) --- ---------- install --- [Please read the precautions on the back before filling this page) 'A wire 8 from the longitudinal end of the first metallized film la The electrode layer 3a and the other wires 8 are preferably pulled out from the electrode layer 4a at the longitudinal end of the second metallized film 1b. Although the method of setting the lead 8 by embedding the lead 8 between the films after the winding step, or the method of setting the lead 8 on the side of the wound film after the thermal bonding step is not considered, but by these methods, It is difficult to electrically connect the electrode layer with the longitudinal end of the film. Therefore, from the viewpoint that the electrode layer can be easily electrically connected to the lead wire, it is desirable to pull out the lead wire 8 from the electrode layer at the longitudinal end of the metallized film 1 & 115 before winding. In this case, the electrode layer 3a, 4a is electrically connected to the wire 8, such as by welding. When explaining the relationship between the first metallized film la and the second metallized film 1b, as shown in FIG. 1, each electrode layer 3 of the first metallized film 1a is formed on the second metallized film 1b The first dielectric film 2a is sandwiched between the two electrode layers 4 adjacent to each other in the longitudinal direction. The dielectric film between the first metallized film la and the second metallized film kilb is not limited to one, such as the second circle, although there are also two dielectric films 2a, 2b that are held in inflammation. Case, but in this case, one of the two dielectric films 2a, 2b has a heat-adhesive resin on its surface, respectively 6 »Printed and clamped on the first metallized film by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The first dielectric film 2a of la and the second metallized film lb, and the heat-adhesive resin layer 6 are composed of a plastic film 5 only on the surface layer. Similarly, the second dielectric film 2b 'is a heat-adhesive resin layer 6 composed of a plastic film 5 pressed only on the surface. As the plastic thermoplastic plastic constituting each of the plastic film 1 and 5, it is ideal. Among them, it may be cheaply obtained. For the reason of so-called chemical and mechanical stability, polyethylene terephthalate, polymer Polypropylene and poly (ethylene terephthalate) are ideal. The paper size of poly-paraben is applicable to China Solid Garden Standard (CNS) A4 (21G X 297 mm) 9 442805 A7 B7 V. Description of the invention (7) Formic acid Ethanol is ideal. (Please read the cautions on the back before filling in this page.) As the thermosetting resin or thermosetting resin constituting the thermosetting resin layer 6, it is acceptable. When using thermosetting resin, roll The wound plastic film does not need to be impregnated with epoxy resin, etc., and can effectively expel the air between the films la to 2b. Therefore, for reasons of suppressing invalid discharge, epoxy resin, phenol resin, and polyurethane resin are used. 2. Acrylic resins and silicone resins are ideal. 'Among them, the air between the membranes 1a to 2b can be most effectively expelled.' Therefore, ineffective discharge can be suppressed more, and the chemical and mechanical stability are more stable. Epoxy resins are more suitable. On the one hand, when a thermoplastic resin is used, it is preferable to use a polyester-based resin or EVA as an olefin-based resin as a main component for the same reason as described above. The films 1a to 2b are sequentially wound on the left (circles are not shown) to make a wound film. The winding speed is about 10 meters / 50 meters / minute. Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. There is no particular limitation on the method of forming the metallized films 1a and 1b. For example, after coating a masking oil on the underside of the plastic film 1, the metal is vapor-deposited and the shielding is removed.

Furthermore, the method of forming the heat-adhesive resin layer 6 on the surface of each of the plastic films 1 and 5 is not particularly limited, and examples thereof include dissolving the heat-adhesive resin in a certain solvent and applying the solution to the plastic film. The method of drying the surface after steps 1 and 5 is the same as the method of directly vapor-depositing the thermal adhesive resin on the surfaces of the plastic films 1 and 5 in the same manner as the metallized film.

Description of the invention (8) Next, the heat-treated winding film is softened by softening The / melt heat-adhesive resin layer 6 adheres each of the films la to 2b. When the heat-adhesive resin layer 6 is a thermosetting resin, although it also depends on the material and properties of the resin, the heat-adhesive resin layer 6 will not be deformed in the fingers even if the shape is pressed at normal temperature before thermal bonding at room temperature. The state of contact hardening (B grade, the state in which the molecules of the resin are two-dimensionally bonded) is melted by heating for 1 hour at a temperature of about 80 degrees Celsius to about 100 degrees Celsius (ideally about 100 degrees Celsius). . When the thermal adhesive resin layer 6 is a thermoplastic resin, although it depends on the material and properties of the resin, it is heated at a temperature of about 80 degrees Celsius to about 130 degrees Celsius (ideally about 100 degrees Celsius). Soften or melt each film la ~ 2b »By heating in this way, after bonding each film la ~ 2b, put the plastic film bonded at normal temperature and harden the thermosetting resin again to obtain a roll-type plastic film Capacitor. In the present invention, only the wound film is heat-treated in this way, and each of the films la to 2b is bonded only by softening / melting the heat-adhesive resin layer 6, and all the plastic films la to 2b are heat-adhesive resin layer 6. It becomes a bonded state, and the air existing between the molds la to 2b is removed by thermal bonding. As a result, the plurality of plastic films after winding do not need to be wetted with epoxy resin or the like, and at the same time, the invalid discharge occurring in the minute gaps (voids) existing in the strong electric field portion (strong electric field portion) on the electrode layer can be suppressed. For a more detailed explanation, as shown in FIG. 3, after the plastic film laminated with the heat-adhesive resin layer 6 is heat-bonded and overlapped with two plastic films la to 2b, the heat-adhesive resin shrinks during cooling. At the same time, the plastic film la ~ 2b also shrinks. On the one hand, the plastic film without heat-adhesive resin is heated to apply the national standard (CNS) A4 (210 X 297 male cage) even if the paper size is cooled after heating.

Description of the invention (9), compared with the plastic film laminated with heat-adhesive resin, it does not shrink so much. Furthermore, even when a plastic film of a heat-adhesive resin is laminated on one side, a metal layer is not laminated on the opposite side (in other words, when a plastic film of a heat-adhesive resin is laminated only on one side) and Compared with the plastic film with the metal layer laminated on the opposite side, the shrinkage is larger. As shown in circle 4a, the two plastic films 9 of the heat-adhesive resin layer 91 are laminated on only one side, and the heat-adhesive resin layers 91a are turned to face each other. Between the thermally-adhesive fat layer 91a of Zhang Plastic 91, a metallized film 92 that forms an electrode layer 92a on only one side of a plastic film is sandwiched. During heating, the heat-adhesive resin is cooled by heating. The layer 91a will shrink, and the two plastic films 91 holding the metallized film 92 will shrink. On the one hand, since the metallized film 92 forming the electrode layer 92a is formed on only one side of a plastic film, the thermal adhesive resin is not laminated. The phenomenon that the so-called metallized film 92 does not shrink so much occurs. In this way, since the shrinkage amounts between the films 91 and 92 are greatly different, there is a tendency that these films peel. The same applies to a dielectric film (Fig. 4b) obtained by forming a heat-adhesive resin layer 93a on both sides of a plastic film 93. "Since the heat-adhesive resin is not laminated on the metallized film, The film does not shrink so much, but the plastic film laminated with the heat-adhesive resin layer on both sides will shrink greatly. As described above, when the two overlapping plastic films are peeled off, ineffective discharge will occur. As a result, the voltage resistance of the capacitor will be reduced. However, in the present invention, the surface (or surface) layer of any of the plastic films la ~ 2b On the one hand, since the heat-adhesive resin layer 6 is not laminated (or on the surface) of any of the plastic films 1a to 2b, the heat-adhesive resin is collected by cooling after heating.

Description of the invention (10) When shrinking, the shrinkage of each plastic film la ~ 2b is as above The capacitor in Figure 4 is not so different compared to '. Therefore, such films are considered to be difficult to peel off. In this way, compared with the conventional capacitor, a high peeling force does not occur between the films, and as a result, it is thought that ineffective discharge can be suppressed. In this way, the heat-adhesive resin layer 6 'is laminated on all the plastic films la ~ 2b, and all the plastic films la ~ 2b are formed by laminating the surface (ie, the surface or the inside) of the heat-adhesive resin layer 6. On the same side, the wound film does not need to be impregnated with epoxy resin, and at the same time, it can prevent peeling between the films, and can suppress invalid discharge caused by peeling. Since no epoxy resin is required, productivity can be improved, and material costs can be reduced. Furthermore, the obtained wound-type plastic film capacitor has approximately the same electric resistance as that of a conventional one impregnated with an epoxy resin. In the present invention, although the wound film is heated, although the temperature during heating depends on the resin constituting the heat-adhesive resin layer 6, it is generally thermosetting or thermoplastic. It is ideal if the temperature is about 80 degrees Celsius or higher and about 110 degrees Celsius or lower. Although the heating time is similar to the resin constituting the heat-adhesive resin layer 6, it is preferably about 30 minutes or more and about 2 hours or less, and about 1 hour is preferred. The pressure given to the wound film during heating is 1 kg / sq. Above 3 cm / cm2 is ideal, and about 2 kg / cm2 is more desirable. As the heating and pressurizing method: ⑴ The method of blowing the warm air and winding the conjunctiva in the state where the kiln is wound between the two boards, and 加热 The state of winding the finished film in the state between the two boards is by heating The method of placing the wound film inside the heating film of the heater.

Although the method of simultaneously applying pressure and heat from the metal plates is listed, it also takes into consideration the cost and economics of heating and pressure injury. The method is ideal. About the ideal heat-adhesive resin, the heat-adhesive resin 6 is non-adhesive at normal temperature, and there is a case where the heat-adhesive resin appears at 50 ° C or higher, regardless of the heat-adhesive resin-based thermosetting property. Resins or thermoplastic resins are clear from the examples described later, which can improve the yield rate of the capacitors obtained. As such a heat-adhesive resin 6, for example, Toyo Textile Co., Ltd. can obtain Byron's 20SS and 30SS. . The heat-adhesive resin layer 6 laminated on the surface of the first metallized film la (hereinafter, the reference sign of the heat-adhesive resin layer 6 is referred to as 61). The heat-adhesive temperature appears only in the first dielectric cross section. The surface of the film 2a has a thermally absorptive resin 6 (hereinafter, the thermally adhesive resin layer 6 is referred to as 62), and the difference in thermal adhesiveness temperature is more preferable for the following reasons. Here, in order to make it easier to understand, it is assumed that the temperature at which the thermal dehydration of the thermal drillable resin layer 61 occurs is lower than the temperature at which the thermal adhesion of the thermally adhesive resin layer 62 occurs. Although the heat of heat #i 合 性 MΜ 6 gradually softens and / or melts the heat-curable resin layer 6 ′, the heat-curable resin layer 61 first softens and / or marries, and the heat-retaining heat The first metallized film 1a of the resinous resin layer 61 and the second dielectric thief film of the first metallized family 1a are wound by a weight of 4. During this period, the heat-resilient resinous layer 62 remains Not softened and / or melted, the first metallized film 1a and the first one holding the thermal adhesive resin layer 62 This paper size applies to China National Standard (CNS) A4 (210 X 297 public love) -14-{Please Please read the notes on the back before filling in this page.) * N ip I »1 ^ ° J 1 line-Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Industrial Consumer Cooperative, printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Consumer Consumer Cooperative A7 B7 5. DESCRIPTION OF THE INVENTION (12) The dielectric film 2a is not adhered. After that, heating is further continued, and when heat is transmitted to the heat-curable resin layer 6, the adhesive resin layer 62 gradually softens and / or melts the first metallized film la and the first metallized film sandwiching the thermal adhesive tree layer 62. 1 dielectric film 2a. In this way, by using the difference in thermal shrinkage between the plurality of plastic films U to 2b between the adhesive films at the stage, the adhesion between the plastic films la to 2b can be prevented from becoming incomplete. Thereby, among all the films of the plastic film la to 2b, it is possible to ensure a uniform and uniform bonding state with little void space remaining after heat treatment. More ideally, the temperature at which the thermal adhesiveness of the thermal adhesive resin layer 61 laminated on the surface of the first metallized film 1a and the thermal adhesion of the thermal adhesive resin layer 6 laminated on the surface of the second metallized film 1b is thermally bonded. The bonding appearance temperature is slightly the same, and the thermal bonding appearance temperature of the thermal adhesive resin layer 62 laminated on the surface of the first dielectric film 2a is the same as that of the thermal adhesive resin laminated on the surface of the second dielectric film 2b. The temperature at which the thermal adhesiveness of the resin layer 6 appears is almost the same. In this case, first, the heat-adhesive resin layer 6 on the metallized film U is first softened and / or melted, and the first dielectric film 2a and the second metallized film lb are bonded. Thereafter, when heating is further performed, the dielectric The thermal adhesive resin layer 6 on the electrical film is softened and / or melted, and the second metallized film 1b and the second dielectric film 2b are adhered. In this way, the difference between the temperature at which the heat-adhesive resin layer 61 and the adhesiveness appear can be more effectively prevented by dividing the thermal contraction rate of the plurality of plastic films la to 2b into two pieces of adhesive film. The adhesion between the films la to 2b becomes incomplete. "Therefore, among all the films of the plastic films la to 2b, a more uniform and uniform adhesive state with less voids remaining after heat treatment can be more surely ensured. As described above, the difference in the temperature at which the thermal adhesiveness of the thermal adhesive resin layer 6 occurs is preferably about 10 ° C or more. When the temperature is less than 10 degrees Celsius, the Chinese National Standard (CNS) A4 specification (21〇χ 297 mm) is applied to the size of the heat-adhesive wood paper. ----------- -Installation ·-Order- -------- Line (Jing first read the notes on the back before filling this page) 15 yl 'Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 2 SO 5 A: _______ B7_____ V. Description of the Invention (I3) Resin The transmission of the heat of the layer 6 does not allow stage-to-stage adhesion between the films, and the specific effect between the stage-to-stage adhesive films may not be fully utilized due to the temperature difference. Regarding the thickness of the film, the thickness of the metallized films 1a, 1b, which is better, and the thickness difference (absolute value) of the dielectric male films 2a, 2b is less than 3 micrometers. The association deteriorates or cannot withstand the load or impact at high temperature, and it may reduce the electrostatic capacity after repeated charging and discharging. This is because the length of the plastic film la ~ 2b in the longitudinal direction is heated by the heat treatment step and during heat treatment. The difference in the amount of shrinkage occurring after the step is large, and it is thought that the adhesion of each of the films la to 2b is reduced. About plastic 臈 la ~ 2b The maximum surface roughness Rmax of plastic film la ~ 2b is more than 0.5 micrometers and 4'0 micrometers or less, more preferably 1.0 micrometers and 32 micrometers or less. Here, the maximum surface roughness Rmax refers to the height between the surface of the most submerged part (concavity and valley) and the most raised part (convex and mountain) of the surface which becomes a small uneven (mountain and valley). (Qi Hou) difference as a definition. Rmax is obtained from a surface roughness measuring device measured by Tokyo Precision Co., Ltd. under the trade name Shafukang (inch-7 3 Z *). When the maximum surface roughness Rmax is less than 0.5 micrometers, it may not be able to withstand negative% at high temperatures, or the electrostatic capacity may decrease after repeated charge and discharge. In this system, because the film surface is too slippery, the tiny concave portions and convex portions existing in some parts of the film surface cannot be engaged. It is believed that there is also a void in the thermal bonding system between the films. On the one hand, if Rmax exceeds 4.0 micrometers, it will not be able to withstand the load at high temperature, or the electrostatic capacity may decrease after repeated charge and discharge. In this series, because the number of tiny protrusions on the film surface makes the palatal surface too thick, there is no standard applicable to this paper @National Standard (CNS) A4 Specification (2〗 〇 " χ 297 公 爱) ---- • 16 , — — — — — — —— — — — — 1, * ^ I 1 III alfilllff I < Please read the unintentional matter on the back before filling in this page), A, Consumer Goods Cooperative of Intellectual Property Bureau, Ministry of Economic Affairs, print A; B7 V.

It is believed that there is still void between the films after thermal bonding. Therefore, in order to eliminate the void between the films, to fully withstand the load at high temperatures, and to maintain stable capacitor characteristics without reducing the capacitance after repeated charge and discharge, the maximum surface roughness Rmax of the plastic film la ~ 2b, It is preferably from 0.5 micrometer to 4.0 micrometer. In this range, when the maximum surface roughness Rmax is less than 1.0 micron, the winding step of the film la ~ 2b and the winding roller (® not shown) which has been wound are slippery, and the film la ~ 2b will have When wound by a winding roller. On the one hand, when the maximum surface roughness Rmax exceeds 3.2 m, the films la ~ 2b slip over the winding rolls and the films la ~ 2b may become serpentine winding rolls. Therefore, when considering such productivity, it is more preferable that the maximum surface roughness Rmax is 1.0 micrometer or more and 3.2 micrometers or less. It is different from the maximum surface roughness. As shown in FIG. 2, between the first metallized film 1a and the first dielectric film 2a, only the surface layer of the plastic film 5 is thermally adhesive resin layer 6 The third dielectric film 2b is further sandwiched between the second metallized film lb and the second dielectric film 2b. The first layer of the thermal adhesive resin layer 6 is laminated only on the surface of the plastic film 5. The case of 4 dielectric film 2d illustrates a preferred embodiment. That is, when two dielectric films 2a, 2b (or 2b, 2d) are sandwiched between the first metallized film 1a and the second metallized film 1b, a plastic film 1 constituting each of the films 1a to 2d, The maximum thermal shrinkage rate of 5 is within 3.0%, and the difference between the maximum thermal shrinkage rates of the two dielectric films 2a, 2b (or 2b, 2d) overlapped is preferably within ι0%. In this 'Maximum thermal shrinkage is the film length direction of the film before heating is L1' Under the condition of 150 degrees Celsius, after heating the film uniformly, the paper size applies the Chinese National Standard (CNS) A4 specification (21G X 297 public love) — — — 1111 — — — — — — · II tl · III allllili — (Please read the notes on the back of the page before filling out this page) 17 A7 B7 V. The film length of the invention description (15) is L2 Is defined as (Ll-L2) / Llx 100 (%). When the difference between the maximum thermal shrinkage of plastic films 1 and 5 exceeds 1.0%, or when the difference between the maximum thermal shrinkage of the two dielectric films 2a, 2b (or 2b, 2d) overlaps more than 1.0%, the capacitor resistance obtained is When the load is not lived at high temperature or the capacitor obtained is between low temperature and high temperature, there is a dimensional difference in the length direction of the two films that overlap, which tends to peel the two films. Regarding the capacitor obtained by the sealing method obtained by the manufacturing method of the present invention, although it can also function as a capacitor as it is, after the heat bonding step, the side of the condensed film (that is, the obtained capacitor) is wound with ultraviolet curability. Tree gambling or certain thermosetting resin seals are ideal. The conventional wound-type film capacitor is made by impregnating the wound end film obtained after the winding step and the thermal bonding step with an epoxy resin. Therefore, when the rolled conjunctiva is lifted from the epoxy resin after dipping, as shown in FIG. 5, the epoxy resin drips on the lower side of the rolled conjunctiva. By dripping the resin, the size (especially the width) of the capacitor finally obtained may cause an error. For this error, because the capacitor is packed in a box, the case where extra space is needed for resin dripping is considered in the case of the invention. »In the present invention, since the winding film (that is, the capacitor obtained) is not immersed in the ring. Oxygen resin, although such resin dripping does not occur, when the side of the capacitor obtained in the present invention needs to be sealed, the glass transition temperature is above 80 degrees Celsius, and the linear expansion coefficient is lx 10.4 mm / mm A thermosetting resin seal below celsius is ideal "to replace such a thermosetting resin. It is also possible to use an ultraviolet curable resin. When sealing the side of the capacitor, if the 5th circle is necessary, the paper size of the two sides must be in accordance with the Chinese Standard (CNS) A4 specification < 210 X 297 mm > < Fill out this >

Description of the invention (16) Sealed. In that case, "the first side is on the upper side and the other side is on the lower side", and the hardening resin is grooved on the upper side and then cured by heating. Then 'turn the capacitor 180 degrees with his side on the top, one side on the bottom, and the same on the other side on the other side, the thermosetting resin is slotted and then heat-cured 0, and when the resin is cured with ultraviolet light' Because it is hardened for a short time, even if it is located at the lower side after being rotated 180 degrees, there is an advantage that no wax dripping occurs. When a thermosetting resin with a glass transition temperature of less than 80 ° C is used, the strength of the resin is insufficient, and when the insulation film breaks inside the capacitor, a discharge will occur on the side of the capacitor, and it will withstand the load at high temperatures. In the case of impact, when using a thermosetting resin, its glass transition temperature is preferably 80 ° C or higher. Similarly, when using a thermosetting resin with a linear expansion coefficient exceeding lx 10.4 mm / mm degrees Celsius, the resin will be rubberized, and the interface between the capacitor body and the buried resin will cause a difference in size, and there will be leakage traces, etc. Poor insulation. In addition, although one type of resin can be used to seal the side of the capacitor, the ultraviolet curing resin, the thermosetting resin with a glass transition temperature of 80 degrees Celsius or higher, and the linear expansion coefficient of lx 10.4 mm / mm Celsius The following thermal bricking resins may be used in combination of two or more kinds.

Description of the invention (18) Each film la ~ 2d-side-winding 'to obtain the rolled conjunctiva. At the time of winding, there are two electrode layers 4 attached to the first metallized film 1a and the second metallized film 1b, and the length of the electrode layer in the longitudinal direction is 300 mm. Place the obtained rolled conjunctiva in a thermostatic bath heated to 100 ~ 200 ° C, or clamp two metal plates heated to 100 ~ 120 ° C to give a pressure of 2 kg / cm2 and pressurize 20 Degree of minutes. As a result, each of the films 1a to 2b is adhered to the heat-adhesive resin layer 6 made of a polyester resin by softening and melting. After bonding, the adhesion between the entire film ia to 2d by the heat-adhesive resin layer 6 was confirmed by enlarging the cross-section between the layers of the photographic film. In order to soften and melt the heat-adhesive resin layer 6, after heating from 100 degrees Celsius to 120 degrees Celsius and cooling, all the films ia ~ 2d shrink slightly, but the shrinkage of each plastic film la ~ 2d is not so large. different. Therefore, no high peeling force is generated between the metal and the film, and the film is not peeled. Therefore, since it becomes difficult to generate ineffective discharge and decrease in withstand voltage. Therefore, according to the manufacturing method of the wound film capacitor of the present invention, the capacitor obtained after the heat treatment step does not need to be impregnated with epoxy resin and impregnated with epoxy resin. The capacitor obtained by the epoxy resin exhibits the same or superior characteristics as 0. Moreover, in this embodiment 1, the thermal bonding temperature using a thermal adhesive resin is 30 ° C, 40 ° C, 50 ° C. For polyester resins at 60 ° C and 60 ° C, the correlation between the thermal bonding temperature step of the thermal adhesive resin and the acceptance rate at the time of winding was investigated.
