近年、可変抵抗器等の電子部品では、耐熱、不燃性等
の面から、セラミック基板を使用する機会が増えてきて
いる。In recent years, ceramic substrates have been increasingly used in electronic components such as variable resistors due to their heat resistance and non-flammability.

付けている。Conventionally, when attaching an eyelet terminal to such a ceramic substrate, as shown in FIG. After insertion, the flat surface 6 of the jig 5 receives the flange part 7 of the eyelet terminal 1, and the tip part 8 of the eyelet terminal 1 is crimped by applying pressure in the direction of the arrow with a punch (not shown). 1 is attached to a ceramic substrate 3.
ところが、ハトメ部４を絞り加工で作つている場合、
ハトメ端子１のハトメ部４とフランジ部７の間にＲ部９
ができる。However, when the eyelet part 4 is made by drawing,

方法が採用できない場合が多い。In this state, if the eyelet terminal 1 is inserted into the ceramic substrate 3 as described above and then tightened, stress will be concentrated on the corner 10 of the ceramic substrate 3 in contact with the R section 9, causing the problem that the ceramic substrate 3 will be easily damaged. It was hot. In addition, in the case of a structure that maintains electrical continuity between the conductive part 11 provided on the ceramic substrate 3 and the flange part of the eyelet terminal 1 as shown in FIG. There was a problem that the electrical contact between the eyelet terminal 1 and the conductive part 11 became unstable. In addition, as shown in FIG. 3, some conventional methods have been adopted in which a tightening part 13 is provided on the flange part 7 of the eyelet terminal 1 by molding using another stage of molding, so that the R part 9 does not contact the ceramic substrate 3. However, with the recent miniaturization of parts, this method is often not possible due to the longevity of the mold.

発明の実施例について第４図〜第６図と共に上記と同一
箇所には同一番号を付して説明する。Further, since there is no gap between the ceramic substrate and the flange portion of the eyelet terminal, electrical contact between the conductive portion provided on the ceramic substrate and the eyelet terminal is also stabilized. Hereinafter, embodiments of the present invention will be described with reference to FIGS. 4 to 6, with the same numbers assigned to the same parts as above.
まず、第４図に示すようにハトメ端子１のフランジ部７

カシメる。First, as shown in FIG. 4, the flange portion 7 of the eyelet terminal 1 is
A counterbore part 1 is placed below the eyelet part 4 of the receiving jig 14.
5, and after inserting the eyelet terminal 1 into the hole 2 of the ceramic substrate 3, the tip 8 of the eyelet terminal 1 is caulked with a punch (not shown).

られる。Then, as shown in FIG. 5, the eyelet part 4 of the eyelet terminal 1
The R portion 9 between the flange portion 7 and the counterbore portion 1 of the jig 14 is
5 embedded. Therefore, stress concentration on the corner portion 10 of the ceramic substrate 3 due to the R portion 9 of the eyelet terminal 1 is eliminated.
Therefore, damage to the ceramic substrate 3 can be avoided. In addition, since the R portion 9 is embedded in the counterbore portion 15 of the jig 14, there is no gap between the ceramic substrate 3 and the flange portion 7 of the eyelet terminal 1, and as shown in FIG. The electrical contact between the electrically conductive portion 11 and the eyelet terminal 1 is also stabilized. As described above, according to the mounting method of the present invention,
When the tip of the eyelet terminal is caulked, the R part between the eyelet and the flange will be embedded in the counterbore part of the jig.
Stress concentration on the corners of the ceramic substrate due to the R portion of the eyelet terminal is eliminated, and as a result, damage to the ceramic substrate is avoided.
