Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a chip-type solid electrolytic capacitor mounted on a printed wiring board of electronic equipment or the like.

BACKGROUND OF THE INVENTION A conventional chip-type solid electrolytic capacitor of this type, as shown in FIGS. 2 and 3, includes a rectangular solid electrolytic capacitor body 1 containing a capacitor element (not shown), and a rectangular solid electrolytic capacitor body 1 containing a capacitor element (not shown). The chip-type solid electrolytic capacitor is attached to a printed wiring board of an electronic device, etc. When mounting, as shown in FIG. 4, the electrode terminals 2 located on the bottom of the rectangular solid electrolytic capacitor body 1 are brought into contact with the printed wiring board 3 and soldered 4 to the printed wiring board. 3 was used for flat surface mounting.

Problems to be Solved by the Invention However, in the conventional configuration described above, the shape of the electrode terminal 2 led out from the capacitor element is only bent along the side surface and the bottom surface of the solid electrolytic capacitor body 1. The degree of freedom in designing a pattern on the printed wiring board 3 of an electronic device or the like is restricted, and as a result, a problem arises in that a targeted design may not be possible or the design may be unreasonable.

In addition, the production of a wide variety of products leads to an increase in production costs, which has the disadvantage that it takes a certain amount of time to develop new products.

The present invention solves these problems and aims to provide a chip-type solid electrolytic capacitor that can be mounted on a printed wiring board of an electronic device or the like on multiple surfaces.

Means for Solving the Problems In order to solve the above problems, a chip-type solid electrolytic capacitor of the present invention includes a rectangular solid electrolytic capacitor body containing a capacitor element, a solid electrolytic capacitor body derived from the capacitor element, and a solid electrolytic capacitor body derived from the capacitor element. An electrode terminal that is bent along the side surface of the solid electrolytic capacitor body along the bottom surface, and a separate electrode terminal that is bent along the adjacent side surface from the side surface of the solid electrolytic capacitor body is added to this electrode terminal. It is.

Effects According to the above configuration, the electrode terminal is derived from the current capacitor element and is bent from the side surface of the square solid electrolytic capacitor body along the bottom surface, and the electrode terminal is bent from the side surface of the solid electrolytic capacitor body to the adjacent side surface. Since separate electrode terminals are added that are bent along the sides, when mounting this chip type solid electrolytic capacitor on a printed circuit board or wiring board of electronic equipment, etc., it is necessary to By contacting the electrode terminals bent along the line 1 and the wiring board and soldering them, not only can the current flat surface mounting be performed, but also the electrode terminals can be bent along the sides of the solid electrolytic capacitor body. This chip-type solid electrolytic capacitor can be mounted vertically by using bent separate electrode terminals and by bringing the separate electrode terminals into contact with the printer/wiring board and performing soldering. In this way, the chip-type solid electrolytic capacitor of the present invention can be mounted on multiple surfaces, so it is easy to design a pattern on a printed wiring board of a target electronic device, etc. using only one chip-type solid electrolytic capacitor. Moreover, since it can be produced by simply changing the shape of the electrode terminal, it is possible to significantly shorten the development time for new products and reduce production costs. Furthermore, this chip-type solid electrolytic capacitor can be mounted not only on the current plane but also vertically, allowing for a smaller pattern area on the printed wiring board and greatly improving the degree of design freedom than before. It is something that can be done.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG. In FIG. 1, reference numeral 11 denotes a rectangular solid electrolytic capacitor body, and this solid electrolytic capacitor body 11 has a capacitor element (not shown) built therein. An electrode terminal 12 is led out from this capacitor element, and the tip of this electrode terminal 12 is bent along the side surface and the bottom surface of the solid electrolytic capacitor body 11. Reference numeral 13 denotes a separate electrode terminal added to the electrode terminal 12, and this separate electrode terminal 13 is bent along a side surface adjacent to the side surface of the solid electrolytic capacitor body 11.

When mounting the chip-type solid electrolytic capacitor with the above configuration on a printed wiring board of electronic equipment, etc., the electrode terminal 12 bent from the side surface to the bottom of the solid electrolytic capacitor body 11 is brought into contact with the printed wiring board and soldered. By attaching it, the current planar mounting can be performed.

In addition, by using separate electrode terminals 13 bent from one side of the solid electrolytic capacitor main body 11 along the adjacent side surfaces, and by bringing the separate electrode terminals into contact with the printed wiring board and soldering, this can be done. Chip-type solid electrolytic capacitors can be mounted vertically.

As an example, the length x width x height dimensions are 7.3 x 4.3
When a x2.8 (nun) chip type solid electrolytic capacitor is mounted on a flat surface, the bottom area is approximately 31 mm, but when mounted vertically as in an embodiment of the present invention, the bottom area is The mounting area is approximately 20M2, making it possible to reduce the mounting area by approximately 40%.

Effects of the Invention As described above, the chip-type solid electrolytic capacitor of the present invention has the solid electrolytic Since separate electrode terminals are added that are bent from one side of the capacitor body to the next to the next, when mounting this chip-type solid electrolytic capacitor on a printed wiring board for electronic equipment, etc. By selectively using two electrode terminals and separate electrode terminals, the chip-type solid electrolytic capacitor can be easily mounted on a plane or vertically.

In other words, since the chip-type solid electrolytic capacitor of the present invention can be mounted on multiple surfaces, it is easy to design a package onto a printed wiring board of a target electronic device, etc. using only one chip-type solid electrolytic capacitor. Moreover, since it can be produced by simply changing the shape of the electrode terminal, it is possible to significantly shorten the development time for new products and reduce production costs. Furthermore, this chip-type solid electrolytic capacitor can be mounted not only on the current plane but also vertically, allowing for a smaller pattern area on the printed wiring board and greatly improving the degree of design freedom than before. It is something that can be done.
