Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite electrical component including a capacitor element.

When connecting high-voltage electrical components, the Electrical Appliance and Material Control Law stipulates a minimum distance between each component for insulation purposes, making it difficult to miniaturize the device and not easy to manufacture.

Due to these circumstances, recently, composite electrical components have been increasingly used in which a capacitor element, a resistor, a diode, etc. are assembled into a single case, and the terminals are brought out to the outside and incorporated into a device.

For example, a composite electrical component that incorporates an MP capacitor element and its discharging resistor into a case is shown in Figure 1.
A capacitor element 5 is built into a case 3 consisting of a cylinder body 1 and a lid 2 so as to be insulated from the case 3 by an insulating paper cylinder 4, and lead wires 6 and 7 drawn out from the capacitor element 5 are connected to the lid 2 and the insulator. Tubes 8 and 9, rubber bushing 10
Terminals 13 and 1 pass through the terminals 13 and 11 and the insulating plate 12
rivets 15 and 16 connected to 4.

These rivets 15 and 16 are further provided with an insulating plate 12.
and a discharge resistor 17 disposed between the capacitor element 5 and the capacitor element 5.
Lead wires 18 and 19 drawn out from the terminal are connected.

That is, since the resistor 17 is located between the insulating plate 12 and the end face of the capacitor element 5, miniaturization is difficult, and
If the resistor 17 is forced onto the end face of the capacitor element 5 in an attempt to forcibly reduce the size, there is a drawback that the characteristics of the capacitor element 5 deteriorate.

Furthermore, connect the lead wires 18 and 19 of the resistor 17 to the rivet 1.
When soldering the resistors 5 and 16, there was also the drawback that the workability was poor because the resistor 17 was not fixed.

In view of the above points, the present invention aims to provide a composite electrical component that can be miniaturized and easily manufactured.

In order to achieve the above object, the present invention provides a composite electric component in which a capacitor element and other electronic elements are housed in a cylindrical body, and the cylindrical body is sealed with a lid having an insulating plate attached near the inner surface. The gist of the present invention is a composite electric component characterized in that a bent portion is provided at the end of an insulating plate, and another electronic element is disposed in the bent portion.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

In FIG. 2, 21 is a cylindrical body made of aluminum metal, etc., and a capacitor element 23 made of oil, MP, etc. is insulated from the cylindrical body 21 by an insulator 22 such as insulating paper or plastic.
is built-in.

Further, 24 is a lid made of aluminum metal or the like, and is caulked to the cylindrical body 21.

A rivet 25, which is an external lead terminal, passes through a hole provided in the lid 24.

The end of the rivet 25 protruding from the outer surface of the lid 24 is spot welded to an external terminal 26.

A plastic insulation tube 27 is arranged around the external terminal 26 for insulation.

Further, an annular rubber bushing 28 is provided on the inner surface of the lid 24 so as to cover the rivet 25.

An insulating plate 29 made of insulating paper, plastic, or the like is attached to the other end of the rubber bushing 28 and the rivet 25.

The insulating plate 29 has both ends surrounding the rubber bushing 28.
As shown in FIG. 3, bent portions 30 and 31 are provided.

Other electronic elements 32 such as resistors and diodes are disposed in this bent portion 30, and a lead wire 33 of the electronic element 32 and a lead wire 34 of the capacitor element 5 are connected to the rivet 25.

That is, both ends of the insulating plate 29 form bent portions 30 and 31 so as to surround the rubber bushing 28, and the electronic element 3
2, the space between the conventional insulating plate and the lid can be used effectively, and the height of the composite component can be lowered, making it possible to downsize the composite component.

Furthermore, assuming that the case dimensions are the same, the electronic element 32
Since the capacitor element 23 can be sealed without being forcibly pressed against the end face of the capacitor element 23, deterioration of characteristics can also be prevented.

In addition, as shown in FIG.
and 37, both ends of which are further folded inward, may also be used.

In this case, by arranging another electronic element on the stepped portion 36 or the stepped portion 37, the electronic element is securely fixed, making it easier to solder the lead wire of the electronic element to the rivet. Ru.

Further, the bent portion does not necessarily have to be bent into an angular shape, and may be a curved surface.

In this case, it is particularly suitable for fixing cylindrical electronic elements.

Furthermore, the bent portions do not necessarily need to be provided at both ends, and may be provided only at one end.

As described above, according to the present invention, it is possible to obtain a composite electrical component that can be miniaturized, is easy to manufacture, and can prevent defects due to deterioration of characteristics during manufacturing.
