【従来の技術】電磁接触器等の電気部品を取付基板に取
り付ける方法として、従来より、ねじ取付、ＤＩＮレー
ル取付による方法が広く採用されている。2. Description of the Related Art As a method of mounting an electric component such as an electromagnetic contactor on a mounting board, a method of screw mounting or DIN rail mounting has been widely adopted.
【０００３】[0003]
【発明が解決しようとする課題】しかしながら、ねじ取
付は、取付基板に穴及びタップ加工した後にドライバー
にてネジ締めるので工数が多くかかる。However, the screw mounting requires a lot of man-hours because the screw is tightened with a screwdriver after forming holes and taps in the mounting substrate.
【０００４】またＤＩＮレール取付は、スナップ取付で
きるが、１，２台を取り付ける時はレールの取付に却っ
て工数がかかり、少量取付には不向きである。Further, although the DIN rail can be mounted by snapping, when mounting one or two units, it takes a lot of man-hours to mount the rails, and is not suitable for mounting a small amount.
【０００５】そこで本発明が解決すべき課題は、レール
等を使用することなく、差し込みだけで電気部品のスナ
ップ取付を可能とすることにある。Therefore, the problem to be solved by the present invention is to enable snap attachment of an electric component only by inserting without using a rail or the like.
【０００６】[0006]
【課題を解決するための手段】前記課題を解決するた
め、本発明は、取付基板の取付穴に電気部品を取り付け

一体に連設し、同帯状板の中央部に前記ケースの下方に
延び、かつ前記取付基板の取付穴よりも自然状態で外方
に突出する可動爪を一体に連設し、同可動爪の下部外方
に傾斜面を形成したものである。In order to solve the above-mentioned problems, the present invention provides a mounting device for mounting an electric component in a mounting hole of a mounting substrate, in which both side walls of an electric component case made of thermoplastic synthetic resin are provided. A movable claw, which is formed by continuously connecting a strip-shaped plate with an opening between them, extends downward of the case at the center of the strip-shaped plate, and projects outward in a natural state from the mounting hole of the mounting substrate. Are integrally connected to each other, and an inclined surface is formed outside the lower part of the movable claw.

【作用】ケースを取付基板の取付穴に装着すると、開口
部を隔てた帯状板の構造のため可撓性に富む可動爪が内
側に撓み、取付穴を通過すると復元力で戻るため、可動
爪が取付穴に係合して電気部品が固定される。When the case is mounted in the mounting hole of the mounting board, the movable claw that is highly flexible due to the structure of the strip plate that separates the opening bends inward, and when it passes through the mounting hole, it returns with a restoring force. Engages with the mounting hole to fix the electric component.

FIG. 4 is an enlarged cross-sectional view of a main part. In these figures, 1 is a case made of thermoplastic synthetic resin, and a strip-shaped plate 3 is integrally connected to a side wall 1a of the case 1 with a predetermined opening 2 therebetween. A movable claw 4 that projects downward from the bottom portion 1b of the case 1 is integrally connected to the central portion of the band-shaped plate 3. The movable claw 4 projects outward from the end surface 7b of the mounting hole 7a of the mounting board 7, and the upper portion thereof has the same surface position as the outer surface of the strip-shaped plate 3 and has a thickness substantially equal to that of the mounting board 7 (see FIG. 2). An engaging pressing portion 4a having an equal height and an engaging portion 4b formed of an inclined surface connecting between the main body portion of the movable claw 4 and the engaging pressing portion 4a are formed, and the movable claw 4 is attached to a lower portion thereof. An inclined surface 4c is formed which enables snap attachment when mounted on the substrate 7. In addition, a removal hole 5 for inserting a tool at the time of removal is formed in the thickness portion of the strip plate 3 above the movable claw 4. Reference numeral 6 in the drawing denotes a fixed leg that is continuously provided in the lower portion of the case 1 and is locked inside the mounting hole 7a of the mounting substrate 7. The movable claw 4 is also formed on the other side wall of the case 1.
【００１０】以上の構成の取付装置の作動について以下
