欠点をもつており有効な対策とは言えなかつた。 In recent years, with the aim of making capacitor parts smaller and lighter and reducing costs, there has been an increasing trend toward using resin for the exterior. Metallic electrode 2 on the surface
A capacitor element 4 in which an insulated wire 3 is connected to the metallic contact electrode 2 is housed so that the side surface of the element 4 becomes the bottom surface, and a sealing resin 5 is filled in the cavity of the resin case 1. be. In such cases, unless the capacitor element is relatively short in length, it is necessary to use sealing resin to keep the sealing thickness constant as the element length increases. Since it has to be used in large quantities, it cannot necessarily be said to be effective from the viewpoint of reducing size, weight, and cost. Therefore, as shown in FIG. 2, metallicon electrodes 7 are formed on both end faces of a resin case 6, and a capacitor element 9 with an insulated wire 8 connected to the metallicon electrode 7 is connected so that the side surface of the element 9 is connected to the resin case 6. The insulated wire 8a connected to the metallicon electrode 7a located on the inner bottom surface of the resin case 6 is led out to the outside while being in contact with the side surface of the capacitor element 9. The opening is sealed with a sealing resin 10 so that the amount of sealing resin 10 used can be further reduced. However, in general, epoxy resin is conventionally used as the sealing resin 10 and vinyl coated wire is used as the insulated wire 8, but since the vinyl surface of the epoxy resin and the vinyl coated wire have poor adhesion, the capacitor element 9 This creates a bypass between the air and the outside air.
Moisture is absorbed from this part during long-term use, and if the capacitor element 9 is impregnated, the impregnated oil leaks from this part, deteriorating various characteristics, and this cannot be said to be an effective countermeasure.
本考案は上記の点に鑑みてなされたもので封口

的とするものである。 The present invention has been made in view of the above points, and aims to provide a resin-clad capacitor with vinyl-coated wire terminals that minimizes the amount of sealing resin used, has good moisture resistance, and does not leak impregnated oil. This is the purpose.

を防止できる利点を有する。 According to the capacitor constructed as described above, the capacitor element 1 accommodates the inner shape of the resin case 17.
Since the shape is the same as that of 1, it is possible to minimize the void space and minimize the amount of sealing resin 18 used.In addition, it is possible to minimize the amount of sealing resin 18 used. Since the covering removal part 16 is provided, the adhesion with the sealing resin 18 is improved and the capacitor element 11 is isolated from the outside air, so there is no bypass, and moisture absorption and impregnated oil leakage can be eliminated, and characteristic deterioration can be prevented. has.

Figure 4 shows capacitors according to the present invention A and conventional example B left in a constant temperature and humidity chamber at a temperature of 40 degrees Celsius and a humidity of 90 to 95% for 8 hours, and then left at room temperature and humidity for 16 hours after being repeated 10 times. This is a measurement of the insulation resistance between each terminal. The sample is A,

ものにも適用できる。 As is clear from Fig. 4, the present invention A is the conventional example B.
The variation and absolute value of the insulation resistance after the test were also excellent compared to that of the previous test, demonstrating the superior effectiveness of the present invention. In the above embodiments, the explanation was made without any particular limitation as to whether to use a solid wire or a stranded wire as the vinyl-coated wire, but in actual use, either one may be used as necessary, but a stranded wire is used. In this case, there is a risk that the gaps between each strand act as a bypass and lead to moisture absorption and leakage of impregnated oil, so if necessary, eliminate the gap between the strands at the connection part with the metallicon electrode and the part where the vinyl coating is removed. It will be more effective if plating is applied. Further, although the above embodiments have been described using one capacitor element as an example, the present invention can also be applied to a case where two or more capacitor elements are used.

By making the inner shape of the resin case the same, the amount of sealing resin is minimized,
It is possible to provide a capacitor that is smaller, lighter, and contributes to cost reduction without deterioration of characteristics.
