Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved structure of a capacitor in which two elements having independent functions are housed in the same case.

In general, a capacitor used for a two-tub washing machine with an independent washing tub and a dehydrating tub is, as shown in FIG. Fifty-two capacitor elements having wires 4 attached thereto are housed, and the opening of the metal case 1 is sealed with a sealing body 7 to which external terminals 6 connected to the lead wires 4 are fixed. However, the device with the above configuration has a large number of parts and requires a correspondingly large number of man-hours, which is an obstacle to automation. Therefore, as shown in FIG. 2, a capacitor element 11 consisting of lead wires 10 attached to metallic electrodes 9 formed on both end faces was housed in a resin case 8, and a filling resin 12 was injected into the cavity of the case 8. It is also being considered to have a structure that eliminates the above drawbacks. However, with the structure as it is, capacitor element 1
There is a risk that the comrades of the capacitor elements 11, especially the metallicon electrodes 9, may come into contact with each other and cause a shot defect.In order to eliminate this risk, the filling resin 12 may be injected while maintaining a sufficient distance between the capacitor elements 11. Although this is conceivable, this would result in an extremely low work efficiency, and therefore it could not be said to be a structure suitable for mass production through automation.

The present invention was developed in view of the above points, and by using a bottomed resin case with a step on the inner bottom, it not only prevents the metallic electrodes of the capacitor element from coming into contact with each other, but also facilitates automation due to poor insulation properties. The purpose of this invention is to provide an inexpensive two-element storage type capacitor that can be used in various ways.

An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 3, a bottomed resin case 24 consisting of two element housing sections 22 and 23 of different heights formed by a step 21 provided at the inner bottom is used. Resin case 24
A metallicon electrode 25 is formed on both end surfaces of each of the element storage parts 22 and 23, and the metallicon electrode 25
A capacitor element 27 formed by attaching a leader wire 26 to
The leading ends of the lead wires 26 are led out to the outside, and the resin case 24 is filled with resin 2.
8 and harden the filled resin. In this case, the level difference 21 needs to have a certain degree of dimension difference depending on the size of the capacitor element used, but the level difference is set appropriately so that the metallicon electrodes do not come into contact with each other even if the capacitor elements are tilted, for example. shall be taken as a thing.

According to the two-element storage type capacitor configured as described above, since the step 21 is provided in the element storage portions 22 and 23, even if the capacitor elements 27 are tilted during the storage process, the metallicon electrodes 25 will not come into contact with each other. It can completely prevent shot defects and has an excellent effect. In the above embodiment, the step structure has been explained by exemplifying a case in which the inner bottom wall thickness is different, but as shown in FIG. Even if used, it will have the same effect.

As described above, according to the present invention, in a two-element housing type capacitor in which two elements having independent functions are housed in the same resin case and filled resin is injected, a step provided at the bottom as the resin case is used. By creating a structure consisting of two element storage sections with different heights, it is possible to prevent the metallic electrode parts of two capacitor elements from coming into contact with each other.This is an inexpensive two-element storage type that can greatly contribute to automation. Capacitors can be obtained.
