産業上の利用分野
本発明は各種電子機器に採用されるプリント基板取付装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printed circuit board mounting device employed in various electronic devices.
従来例の構成とその問題点
近年、電子機器のフレームにプリント基板を取付ける作
業にも自動化が取入れられてきている。Conventional configurations and their problems In recent years, automation has been introduced to the work of attaching printed circuit boards to the frames of electronic devices.
したがって、このようなプリント基板の取付作業も容易
で正確な位置決めと取付けが重要視されるようになって
きた。Therefore, importance has been placed on easy and accurate positioning and mounting of such printed circuit boards.
以下、図面を参照しながら、上述したようなプリント基
板取付装置について説明する。Hereinafter, the above-described printed circuit board mounting apparatus will be described with reference to the drawings.
まず、第１図に示すものは、電子機器のフレーム１に切

一部の近くに位置決め孔６を設けたプリント基板７を配
置し、このプリント基板７をビス８により取付片２に締
付けて取付ける構成となっていた。First, what is shown in FIG.
A screw hole 3 is provided on the top surface of the mounting piece 2, a positioning piece 4 is provided on the top surface of a part of this mounting piece 2 so as to protrude upward, and various electronic components are assembled on this mounting piece 2. i Place a printed circuit board 7 with screw holes 6 at four corners and positioning holes 6 near some of the screw holes 6, and attach this printed circuit board 7 to the mounting piece 2 with screws 8. It was designed to be installed by tightening it.

た。In addition, the one shown in FIG. 2 has several mounting pieces 2 cut and raised on the frame 1 of the electronic device, and an inverted-shaped locking piece 9 and a fixing piece 1° on the top of the mounting pieces 2. The printed circuit board 7 to be attached here has as many long holes 11 as the number of mounting pieces 2, and the printed circuit board 7 is fitted into the upper part of the mounting piece 2 using the elongated holes 11, and the printed circuit board 7 is inserted into the upper part of the long hole 11. The lower part of the printed circuit board was attached to the frame 1 by twisting the protruding locking piece 9 and engaging it with the upper surface of the printed circuit board 7.
上記第１図に示すものは、プリント基板下の支持面が大

ビス８を締付ける際にプリント基板７がゆがめられてそ
のねじ孔６と位置決め孔６間に応力がかかってヒビ割れ
や欠けが生じるといった欠点があった。The one shown in Figure 1 above has a large support surface under the printed circuit board and is fixed with screws 8, so it is secure and stable, but it requires a large number of parts, increases man-hours, and is difficult to install. Since the piece 2 is bent into an L-shape, it is necessary to perform the bending process three times, which complicates the mold, makes it difficult to obtain precision, and makes positioning difficult. Because the holes 6 are close to each other, if the mounting piece 2 is not flat or the printed circuit board 7 itself is warped, the printed circuit board 7 will be distorted when tightening the screws 8 and the screw holes 6 and positioning holes will be distorted. There was a drawback that stress was applied between the holes, causing cracks and chips.
また、第２図に示すものけ、取付片２とプリント基板７
の長孔１１との嵌合により位置決めし、係止片９をひね
ることで固定できるため、作業性に優れるが、係止片９
をひねる動作があるため。In addition, the mounting piece 2 and the printed circuit board 7 shown in FIG.
The locking piece 9 can be positioned by fitting into the elongated hole 11 and fixed by twisting the locking piece 9, so it has excellent workability.
Because there is a twisting action.
長孔１１に横方向の応力が生じ、プリント基板７に割れ
を誘発することになり、プリント基板７を支える面積も
小さく、固定の安定性に欠け、その反面固定する数を増
加すれば位置決めが困難になるといった欠点があった。Lateral stress is generated in the elongated hole 11, inducing cracks in the printed circuit board 7, and the area supporting the printed circuit board 7 is also small, lacking stability in fixing.On the other hand, increasing the number of fixed holes makes positioning difficult. It had the disadvantage of being difficult.
