Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to electrical components, and more specifically, to electrical components formed by chipping components such as aluminum electrolytic capacitors.

[Conventional example]

When electrical components are mounted on a circuit board using an automatic machine and soldered, etc., it is preferable for the electrical components to be made into chips for handling reasons.

Many proposals have been made for converting electrical components into chips, and for aluminum electrolytic capacitors, for example, the following method is known.

As shown in Japanese Patent Application Laid-Open No. 59-211213,
An electrical insulating plate with a lead insertion hole and a recess connected to the lead insertion hole is placed on the sealing side end of an aluminum electrolytic capacitor with the same direction of lead wires, and the capacitor's leads are bent to fit within the recess to form a chip. do.

An exterior body made of resin mold is formed around the outer circumference of an aluminum electrolytic capacitor, and the leads of the capacitor are bent along the surface of the exterior body.

[Problems to be Solved by the Invention] Although the above method has a simple structure and is inexpensive, it is not preferable in terms of downsizing the device because it is placed vertically when mounted on a circuit board.
On the other hand, although the conventional example described above can be mounted horizontally on a circuit board, it has the disadvantage that it takes time and cost to mold the exterior body.

This invention was made in view of the above-mentioned drawbacks of the conventional example, and its purpose is to provide an electrical component that has a simple structure, can be made into a chip at low cost, and can be mounted horizontally on a circuit board. It is about providing.

As shown in FIG.
includes a component body 2 and a frame member 3 attached to the component body 2. In this example,
As the component body 2, a capacitor element (not shown) is inserted into a cylindrical metal outer case 4 with a bottom, the opening thereof is closed with a sealing body 5 made of rubber or the like, and a 1 is connected to the capacitor element. An aluminum electrolytic capacitor is used in which a pair of leads 6 and 7 are drawn out through a sealing member 5 and the leads are directed in the same direction. Note that the surface of the outer case 4 is
It is preferable to keep it in an electrically insulated state by applying a heat-shrinkable electrically insulating sleeve, applying an electrically insulating paint, or forming an electrically insulating oxide film.

Referring to FIGS. 2 and 3, the frame member 3 includes a frame body 9 made of an electrically insulating material and having a mounting recess 8 that is fitted into the outer case 4 of the component body 2;
It has a pair of leg portions 10 and 11 formed parallel to each other along the axial direction of the exterior case 4 from a predetermined portion of the frame body 9.

According to this embodiment, the frame body 9 includes the component body 2.
A notch 12 is provided for fitting the mounting recess 8 into the mounting recess 8 from a direction perpendicular to the axis thereof.
That is, the frame main body 9 is elastically deformable, and is elastically fitted into the outer case 4 of the component main body 2 by expanding the notch 12 thereof. Note that a taper 13 is provided on the shoulder portion of the frame body 9 to indicate polarity. In this embodiment, the legs 10 and 11 are arranged on both sides of the notch 12, and guide grooves 10a and 11a are provided on the bottom surfaces thereof, respectively, for attaching the leads 6 and 7. In this regard, predetermined portions of the leads 6 and 7, that is, portions 6a and 7a attached to the legs 10 and 11, are formed flat by, for example, press processing.

In the above configuration, this electrical component is assembled as follows. First, the notch 12 of the frame body 9 is expanded and the outer case 4 of the component body 2 is fitted into the mounting recess 8 from the notch 12 .
In this case, since the component body 2 is an aluminum electrolytic capacitor, it is preferable to fit the not-illustrated horizontal constriction portion of the outer case 4 into the mounting recess 8. In this embodiment, the frame body 9 is attached to the component body 2 by its elastic restoring force, but an adhesive may be used depending on the case. Next, connect the leads 6 and 7 to the leg 1.
By bending it along the guide grooves 10a and 11a of 0 and 11, a horizontal chip-shaped electric component 1 is obtained. In that case, by forming engagement grooves 14, 14 on the upper surface side of the legs 10, 11, and engaging the ends 6b of the leads 6 in the engagement grooves 14 as shown in FIG. 6 and 7 as leg part 1
0 and 11 can be attached more firmly. Further, as shown in FIG. 4, by exposing a part of the outer case 4 from the notch 12 and aligning the exposed surface with the contact surfaces of the leads 6 and 7 with respect to the circuit board 15, the circuit It becomes possible to place this electrical component 1 on the board in an extremely stable state.
