Description of the invention (2) Devices Cl, C2 'C3, .... C8 in series. In each of the capacitors Cl, C2, C3, ..., and C8, the voltage Vs applied between the wires 3a, 3b and the divided Vs V2, V3, ..., V8 are received, so the withstand voltage is increased, and the battery can be applied with high voltage. Voltage. In addition, after such a voltage is wound up, it is necessary to vacuum impregnate a liquid thermosetting resin such as epoxy resin. Fig. 13 shows a capacitor element impregnated with epoxy resin. The capacitor element is supported by the wires 3a, 3b, and the end face of the lead on the winding side or the side of the winding side is impregnated upward. Cell elements impregnated with ring resin are impregnated—socks are removed after a fixed period of time to harden the resin. By the infiltration operation, the air layer (hereinafter referred to as the air gap) existing between the dielectric thin films 13 and 11? Is replaced by the epoxy resin phase, and the pinholes ( The defective parts such as pin hole are also filled with epoxy resin. Due to this infiltration operation, the withstand voltage of a certain thickness of the dielectric can be increased, and the enhancement of the strength of the wire and the prevention of the moisture absorption of the product can be taken into consideration at the same time. In this way, a small high-voltage capacitor with a rated voltage of 10 to 30KV and a capacitance of 1000 to 6000PF can be obtained without a container. Batteries of this specification are often occasionally used in electrical connections made by dissolving the conductive rubber by soldering wires to the feet of electronic equipment. Electrically connected batteries are embedded in high-voltage resins such as epoxy resin. However, a hardening resin such as an epoxy resin is hardened after being impregnated, and a strong resin film having a thickness of several Å is formed on the surface of the lead wire. The above resin coating may cause the conduction failure of the soldered portion. In addition, by welding. When the conductive rubber is contacted to obtain an electrical connection, the resin film also causes a poor conduction.

Description of the Invention (3) Therefore, there is a method to impregnate the wire in a solder bath, decompose the resin film, and then form solder. The layer considers its countermeasure. However, in the above countermeasures, since the removal of the strong epoxy coating and the formation of the tin layer are performed at the same time, there is a problem that it takes time and reduces productivity. In order to completely solve the above-mentioned problem of poor conduction, the epoxy coating on the wire must be completely removed or not adhered. ^ To remove the resin Although there is a method of forcibly removing the resin by using an abrasive, etc., it is not only difficult to completely remove it, but also sometimes The solder layer on the surface of the wire may be damaged so that the solderability is reduced. In addition, the lead may be cut during removal. Therefore, some people have also thought of a method of coating the surface of the lead wire with a release resin to prevent or reduce the adhesion of the earth resin. However, if the release agent adheres to the end face or the periphery of the capacitor element, the resin impregnation is not ideal, and the withstand voltage characteristic of the capacitor is reduced. That is, in previous thin-film batteries, especially high-voltage capacitors, how to increase the withstand voltage of the battery at a low cost and take into account the pursuit of miniaturization and the continuity of the lead wires are its subjects. The present invention is a film capacitor, especially an electronic component part which needs to be impregnated with resin, which is represented by a film capacitor for high voltage. Its purpose is to reduce the adhesion of the resin to the wire, and to easily remove the resin film to ensure the quality of the electronic part And improve its weldability. [Summary of the Invention] The electronic component of the present invention is formed on the surface of the lead wire with a moldable resin film having an average thickness of 〇Α to 1000 persons. The resin film is preferably a resin containing a cured product of a reactive polysiloxane or a resin containing at least a part of a structure containing a fluorocarbon. In addition, the paper wire of the present invention is made in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the notes on the back before filling in this I) 丄 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs

[First specific example] The first form of the present invention will be described with reference to the first figure. The first figure shows the cross section of the lead wire according to the first embodiment of the present invention. The diameter is 0 5mm. A copper plating layer 28 with a thickness of 30 / im is formed on the outer periphery of the flexible steel wire 2A and a solder coating layer 2C with a thickness of 10 m is formed on the outer side. 2B, 2C are formed by electroplating after the wire is stretched.

In the figure, the surface tension between rsl 疋 wire and epoxy, ^ is the surface tension of the wire, Η is the surface tension between the liquid epoxy, and 0 is the contact angle. The surface of the wire with the silicone film and the epoxy resin The contact angle will increase. That is, the silicone coating is formed on the surface of the lead wire used in this embodiment. Therefore, the ring-shaped resin is easily pulled off. Next, the third figure shows that the thickness of the silicon-containing resin is i.

Explanation of the invention (6) Degree of easy connection) and JIS-C-5102 The detailed results of the connection between JIS-C-5102. As shown in Figure 3, the thickness of the silicone resin coating film is 10 A to 1 〇 〇〇A, it can meet the characteristics of both the drop-out and solderability of epoxy resin. In the extremely thin range of silicone resin film below 1000A, the surface tension between the wire and the molten solder will exceed the lithone on the surface of the wire The surface tension of the film. Therefore, 'the solderability can be satisfied> "A thickness less than 10 A is insufficient to form a silicone film and cannot exhibit epoxy releasability" On the other hand, if the thickness of the silicone resin exceeds 300 people, the solder is full The wet test (Meines table method) tends to reduce solder turbidity (it takes time to wet the solder). Therefore, if soldering is performed for a short period of time, the thickness of the film thickness of Shi Xiyu resin is about 50 to 300A. should. As described above, it is a feature of this embodiment that a moldable resin is molded on a lead wire, and electrical connection is secured in a short time. Next, the materials used in this embodiment will be described using the chemical formulas shown in Figs. 4A and 4B. The two chemical formulas shown in FIG. 4 represent the reactive polysiloxane, which is the main component of the silicone resin used in this embodiment. After adding a platinum complex catalyst as the main component to the two types of reactive polysiloxanes shown in Figure 4, the silicone resin with methyl groups is formed on the surface of the wire after being coated on the wire. Floor. Fig. 5 shows an estimated mechanism of the epoxy resin mechanism of the silicon snapper resin. As shown in Fig. 5, since the fluorene group in the silicone resin faces the surface side, it is estimated that the epoxy resin can be dropped off. In addition, although a silicone resin is used for the surface treatment in this embodiment, the surface treatment material of the lead wire used in the present invention is not limited to the silicone tree.

Dilute the solution 100 times. Put the above-mentioned treatment solution into the container to impregnate the wire for 30 minutes. Then, discharge the above-mentioned treatment solution, at this time, attach the treatment solution to the surface of the wire. Then, after the treatment solution is discharged, it is left at room temperature After drying for about 60 minutes, the container was directly placed in a thermostatic bath and thermally cured at 100 ° C for about 100 minutes.

When the wire is passed through the hair impregnated with the ketone solution, a silicone solution will adhere to the surface of the wire. d is a calender die 'on the surface of the wire made of diamond, and the diameter of the die is approximately the same as the diameter of the wire and is circular. The wire with the broken ketone solution passed through it. When passing through the mold, too much Shi Xiyu's liquid was peeled off ', thus forming a very thin and uniform silicone resin mold for 100 people. In this embodiment, the thickness of the resin mold can be adjusted by adjusting the speed of the wire passing through the mold. Using the manufacturing method of this embodiment, the epoxy resin drop-out property and JIS-C of the silicone resin mold wire can be adjusted. The weldability specified by -5102 is as good as that in the second embodiment. [Fourth specific example] Next, a method for manufacturing a high-voltage capacitor according to a third embodiment of the present invention will be described using the eighth to the ninth. Fig. 8 shows an embodiment of the high-voltage capacitor of the product of the present invention. In Fig. 8, electrodes 2a '2b are arranged on both sides of the dielectric thin film ia, which are formed of a metal foil or a metal layer formed by thermal spraying, and are arranged in the longitudinal direction at regular intervals. The electrodes 2a, 2b composed of such metal layers are individually arranged as islands by insulated electrodes, and the electrodes 2b are arranged as electrodes formed by two metal layers adjacent to the other side of the dielectric thin film la 2c, 2d face each other. The lead-out wire of the electrode is a wire with a silicone resin mold welded on the electrode surface at least at the beginning of the winding part or the winding end part. In the example shown in Fig. 8, the wire 6a is fused on the winding start side and the wire 6b is fused on the winding end side. The electrical connection between the electrode and the wire is carried out through the fusion joints 4a and 4b.

Description of the invention (9) 0 High pressure of this embodiment Capacitors are rolled up with a dielectric film la and other dielectric films lc formed by electrodes 2a '2b' 2c '2d and the like composed of metal layers on both sides. During the winding process, the two End or-The side end can pull the wire out. Fig. 9 shows a state in which the resin of the high-voltage capacitor of the product of the present invention is wet-hardened. When wetting in resin, connect the lead wire of the capacitor element to the infiltration mold with adhesive tape, immerse the whole element containing the lead wire in epoxy resin, take out the element, and harden the wetted epoxy resin at a certain temperature. To ensure the physical properties of the resin. At this time, the epoxy resin formed on the conductive wire formed by the silicone resin needs to be pulled off, and the amount of epoxy resin adhered to the conductive wire is extremely small. In addition, a part of the adhesion-hardened epoxy resin 5a has a spherical shape, and the adhesion strength to the wire is extremely small. Therefore, it is easy to remove the attached epoxy resin by sandwiching the wires with a pair of dulcon, duracon, or non-woven cloth, and wiping it several times in the direction of the wires. The force required for the epoxy ball attached to the wire of the silicone resin mold (unit: kg). {Please read the precautions on the back before filling out the wif page) — — — — — — — «— — 111 II 1 I.

Invention Note (10) (Please read the precautions on the back of this page before filling in this page.) From Table 1, you can see that the force required to remove the adhesion resin on the wire where the silicone resin mold is formed is 10% or less of the uncoated product. That is how easy it can be removed with your fingers. Therefore, in this embodiment, the resin balls described above can be removed without causing any damage to the wires. In contrast, when the above-mentioned capacitors without a silicone resin molded lead are mechanically removed from the resin, a lot of scratches are generated on the surface of the lead. The solderability of the capacitor lead manufactured by this embodiment shows the same good results as in the second embodiment. In the description of this embodiment, although an example of a high-voltage capacitor is specifically described, generally, a film capacitor with a lead wire is formed by using a lead wire having a moldability of an organic insulating resin mold formed in advance, and it is similarly easy to manufacture the capacitor. The effect of removing excess wetting resin and overcoating resin on the attached wires at this time is not limited to high-voltage capacitors. As described above, according to the present invention, the container of the lead wire of the capacitor is used as a unit, or the resin is continuously molded during the manufacturing process of the lead wire, so that the amount of the resin die adhered to the lead wire when the resin is wetted is small. In addition, since it is easy to remove the adhered resin, it is possible to obtain a thin film capacitor having sufficient capacitor characteristics and improved electrical conductivity to external electrodes. Printed by a member of the Intellectual Property Bureau of the Ministry of Economic Affairs and printed by a consumer cooperative. In addition, in the above description, capacitors are mainly described, but the wire of the present invention is not limited to thin film batteries. It is needless to say that all the electronic components with lead wires that are impregnated with resin or covered with resin can be used effectively.
