挿入するように形成したものである。(Means for Solving the Problem) In order to solve the above-mentioned problem, the electronic component mounting foot of the present invention includes a plurality of flat plates arranged on substantially the same plane and each having a width smaller than the diameter of the printed circuit board insertion hole. Of the shaped mounting feet,
The inner spacing (outer spacing) of at least two mounting legs is smaller (larger) than the inner spacing (outer spacing) of the two opposing insertion holes, so that it is forcibly inserted into the printed circuit board. It is something.

ツキは少なく、挿入力のバラツキも少なくなる。また弾
性をもって挿入するため、挿入し易くまた、脱落し難く
なっている。(Function) With this shape of the mounting foot, the mounting foot remains flat even after processing, so the bending process is reduced, there is little variation in dimensions after processing, and there is also less variation in insertion force. Furthermore, since it is inserted with elasticity, it is easy to insert and difficult to fall off.
（実施例）
第３図及び第４図は、本発明のスイッチケースに適用し
た一実施例を示すものである。(Embodiment) FIGS. 3 and 4 show an embodiment of the present invention applied to a switch case.
図において２１．２２は金属性の取付足で、ケース２３
内にて内部接点とカシメ等により固着されている。In the figure, 21 and 22 are metal mounting feet, which are attached to the case 23.
It is fixed inside by internal contacts and caulking.
このとき上記取付足２１．２２の先端はテーパ部２３゜
２４．２５，２６が設けられ、プリント基板３３の相対
する挿入孔３４ 、３５に挿入し易いようになっている
。At this time, the tips of the mounting legs 21, 22 are provided with tapered portions 23°, 24, 25, 26, so that they can be easily inserted into opposing insertion holes 34, 35 of the printed circuit board 33.
また先端から基板受は部２９．３０迄の挿入部の幅はプ
リント基板３３の挿入孔３４．３５の径より小さく且つ
、挿入部の内側間隔が挿入孔３４．３５の内側間隔より
小さくなるように基板挟持部２７．２８を設ける。In addition, the width of the insertion portion from the tip to the board holder portion 29.30 is smaller than the diameter of the insertion hole 34.35 of the printed circuit board 33, and the inner spacing of the insertion portion is smaller than the inner spacing of the insertion hole 34.35. Substrate holding parts 27 and 28 are provided at.
これにより基板挿入時には取付足２１．２２の挿入部の
内側間隔が挿入孔３４．３５の内側間隔より小さくなっ
ているため、脚部３１．３２及び取付足２１．２２自体
の弾性により挟持部２７．２８がプリント基板３３の挿
入孔３４ 、３５の内側を挿入方向と垂直な方向にそれ
ぞれ相対する方向で力を加えることになり、これにより
取付足２１．２２はプリント基板３３を挟持することに
なる。As a result, when inserting the board, the inner distance between the insertion portions of the mounting legs 21.22 is smaller than the inner distance between the insertion holes 34.35, so the elasticity of the legs 31.32 and the mounting feet 21.22 itself causes the clamping portion 27 to .28 applies force to the inside of the insertion holes 34 and 35 of the printed circuit board 33 in directions perpendicular to the direction of insertion, respectively, and as a result, the mounting legs 21 and 22 clamp the printed circuit board 33. Become.
また脚部３１．３２の間隔をプリント基板３３の挿入孔
３４．３５の内側間隔と同一寸法か、それ以上になって
いるため、挟持部２７．２８と挿入孔３４．３５のそれ
ぞれの内側間隔の差により、挿入後の脱落がし難くなっ
ている。In addition, since the distance between the leg portions 31.32 is the same as or larger than the inner distance between the insertion holes 34.35 of the printed circuit board 33, the inner distance between the holding portions 27.28 and the insertion holes 34.35 is This difference makes it difficult to fall off after insertion.
（発明の効果）
本発明は以上の如く構成されるものであり、取付足形状
が平板状であるため、加工し易く、また曲げ加工等の工
数削減になり、寸法精度も良いので、プリント基板挿入
力及び脱落力のバラツキも少なくなる。(Effects of the Invention) The present invention is constructed as described above, and since the mounting foot shape is a flat plate, it is easy to process, reduces the number of man-hours such as bending, and has good dimensional accuracy. Variations in insertion force and removal force are also reduced.
また上記取付足を絶縁成形材料により根元部を成形加工
した後、同時打抜き加工によりプリント基板挿入部を形
成するものであれば、寸法精度のより高い且つ挿入時の
応力に対する耐力の高いスナップインになるものである
。In addition, if the base of the mounting foot is molded with an insulating molding material and the printed circuit board insertion part is formed by simultaneous punching, the snap-in will have higher dimensional accuracy and high resistance to stress during insertion. It is what it is.
また、スイッチ等の電子部品において、上記取付足がス
イッチ等の内部接点と一体化しスイッチ端子を共用する
ように形成するものであれば、構成部品の点数削減も図
ることができるものである。Further, in electronic components such as switches, if the mounting feet are formed so as to be integrated with the internal contacts of the switch and share the switch terminals, the number of component parts can be reduced.
また脚部を、その長さがプリント基板の厚み以上となる
ようにし内側間隔が挟持部より小さく且つ挿入孔の内側
間隔より大きい凹部にすることにより、挿入時には挟持
部が基板挿入孔を離れる。Further, by making the leg portions have a length equal to or greater than the thickness of the printed circuit board and forming a recessed portion with an inner distance smaller than the holding portion and larger than the inner distance of the insertion hole, the holding portion leaves the board insertion hole during insertion.
この時、脚部の内側間隔は挿入孔の内側間隔より大きく
しである為、第５図に示すようにプリント基板と挟持す
ることになり、且つ挟持部は電子部品の抜は止めになる
。これにより、自動半田槽等のコンベアの振動による電
子部品の浮き、はずれ等を防ぐことができる。At this time, since the inner spacing of the legs is larger than the inner spacing of the insertion hole, they are clamped to the printed circuit board as shown in FIG. 5, and the clamping portions prevent the electronic component from being pulled out. This can prevent electronic components from floating or coming off due to vibrations of a conveyor such as an automatic soldering tank.
なお、特許請求の範囲第（１）項及び第（２）項に記載
されているように、「内側間隔」を「外側間隔」に。In addition, as described in claims (1) and (2), "inner interval" is changed to "outer interval".
「小さく」を「大きく」に、「大きく」を「小さく」に
