Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to radial electronic components constituting various electronic devices.

BACKGROUND OF THE INVENTION Conventionally, this type of radial electronic component has had a configuration as shown in FIG. In FIG. 3, 1 is a characteristic element such as a varistor. Reference numeral 2 denotes counter electrodes provided on two opposing surfaces of the characteristic element 1, respectively. Reference numeral 3 denotes two metal conductive wires led out from the counter electrode 2 in parallel with the counter electrode 2 and in the same direction, and lead out the basic characteristics of the characteristic element 1 to the outside. Reference numeral 4 is an insulating resin that covers the characteristic element 1 and the counter electrode 2. At this time, a portion 41L (hereinafter referred to as a foot sagging portion) where the insulating resin 4 is thinly attached is formed in a portion of the metal conductive wire 3 near the characteristic element 1.

FIG. 4 shows a case where the above-described conventional radial type electronic component is mounted on a printed circuit board. Here, the foot hanging portion 41L may enter the hole of the printed circuit board 5, and the solder 6 may not come into contact with the metal conductive wire 3.

Problems to be Solved by the Invention In such a conventional configuration, there was a problem in that the dripping portion of the insulating coating entered the hole in the printed circuit board, and the metal conductor wire was not soldered during soldering work.

The present invention solves these problems, and is a patent that is characterized in that metal wires can be reliably inserted into holes in printed circuit boards, and soldering can be performed easily.

Means for Solving the Problem In order to solve this problem, the present invention provides opposing electrodes on each of the two opposing sides of the characteristic element, and provides two electrodes parallel to and in the same direction from the opposing electrode. A metal conductor wire is drawn out, a bent portion is provided at a portion of the metal conductor wire closest to the characteristic element, the characteristic element, the counter electrode,
The bent portion is covered with an insulating resin.

Effect: With this configuration, the diameter of the foot hanging portion becomes thicker due to the bent portion of the metal conductor, so when mounted on a printed circuit board, the foot hanging portion will not get into the hole in the printed circuit board, and the metal conductor wire will be reliably soldered. This makes it highly reliable.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a front cross-sectional view of a radial electronic component in one embodiment of the present invention. In FIG. 1, numeral 11 is a characteristic element such as a varistor, which is an element showing the basic characteristics of a radial type electronic component. Reference numeral 12 denotes opposing electrodes provided on two opposing surfaces of the characteristic element 11. Reference numeral 13 denotes two metal conductive wires led out from the counter electrode 12 in parallel with the counter electrode 12 and in the same direction, and leads out the basic characteristics of the characteristic element 11 to the outside.

131L is a bent portion provided at a portion of the metal conducting wire 13 closest to the characteristic element 11. 14 is an insulating resin such as epoxy, and characteristic element 11. The counter electrode 12 covers the bent portion 13a.

Regarding the radial type electronic component configured as above,
The operation will be explained below.

First, the basic characteristics of the characteristic element 11 are led out through the counter electrode 12 and the metal conducting wire 13. That is, the basic characteristics of the characteristic element 11 are shown between the two metal conductive wires 13.

FIG. 2 shows a case where the radial type electronic component of this embodiment is mounted on a printed circuit board. In this embodiment, since the bent portion 13 & is provided in a portion of the metal conductive wire 13 close to the characteristic element 11, the foot hanging portion 142L is much thicker than in the conventional example described above. Therefore, the foot sagging portion 15& does not enter the hole of the printed circuit board 16, and the solder 16 is reliably soldered to the metal conductive wire 13.

Effects of the Invention As described above, according to the present invention, opposing electrodes are provided on two opposing surfaces of a characteristic element, and two metal conductive wires are led out from the opposing electrodes in parallel with the opposing electrodes and in the same direction. , a bent part is provided at a portion of the two metal conductive wires closest to the characteristic element, and the characteristic element, the counter electrode, and the bent part are coated with an insulating resin, so that the foot sagging part is prevented when mounted on a printed circuit board. The metal conductor wires are reliably soldered without entering the holes in the printed circuit board, making it possible to realize highly reliable radial type electronic components, which has great practical effects.
