本発明は絶縁物を各プリント基板に挿入した制御機器に
関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device in which an insulator is inserted into each printed circuit board.
従来の技術

の絶縁をしている。（図 では、２枚のプリント基板を
使用した例を示しているが、基板は何枚でもよい。）
発明が解決しようとする問題点
このような制御機器では、単に上基板と下基板の絶縁を
行っているだけであり、上基板と下基板でノイズ等によ
シミ気的相互干渉を起こしやすく、機器が誤動作しやす
い。最近ではマイクロコンピュータ（以上マイコンと称
す）を塔載した機器が増えてきており、各基板から発生
するノイズによりマイコンが暴走することが度々ある。BACKGROUND ART FIG. 3 shows a general control device. In Fig. 3, the insulator 1 is inserted between the upper substrate 2 and the lower substrate 3, and the
insulation. (The figure shows an example using two printed circuit boards, but any number of printed circuit boards may be used.) Problems to be Solved by the Invention In such control equipment, it is difficult to simply insulate the upper and lower boards. However, the upper and lower boards tend to cause mutual interference due to noise, etc., and the equipment is likely to malfunction. Recently, the number of devices equipped with microcomputers (hereinafter referred to as microcomputers) has been increasing, and the microcomputers often go out of control due to noise generated from each board.
ノイズ対策としては、各基板内でフィルタ（インダクタ
ンス、コンダクタンス等）でノイズ低減を行う方法が用
いられるが、基板の相互間の干渉による誤動作は防止で
きない。As a noise countermeasure, a method is used in which noise is reduced using a filter (inductance, conductance, etc.) within each board, but malfunctions due to interference between boards cannot be prevented.
本発明は従来例の問題点を解決するもので上基板と下基
板の絶縁に加え、電気的相互干渉も防止しノイズ誤動作
を防ぐことを目的としている。The present invention solves the problems of the prior art and aims to prevent noise malfunctions by not only insulating the upper and lower substrates but also preventing mutual electrical interference.
問題点を解決するだめの手段
問題点を解決するために、金属の両面を絶縁物ではさん

An insulating sheet is inserted between the and lower substrate 3, which has a laminated structure in which both sides of the metal 5 are sandwiched between insulators 4 and 6, and is placed slightly inside the outer periphery of the insulators 4 and 6 so that the metal 5 is not exposed. do. If the metal 5 is connected to GND as shown by the arrow, it will be even more effective. 7 is a penetrating rod that penetrates the upper substrate, the insulating sheet, and the lower substrate.
第２図は本発明の上面図を示している。８は貫通棒７用
の穴部を示しており、ここでも金属５が゛露出しないよ
うに絶縁物４、 の内側に配設する。FIG. 2 shows a top view of the invention. Reference numeral 8 designates a hole for the through rod 7, which is also placed inside the insulator 4 so that the metal 5 is not exposed.
金属５は、アルミ等の金属板でもよいし、また絶縁物に
蒸着したものでも印刷したものでもよい。The metal 5 may be a metal plate such as aluminum, or may be vapor-deposited on an insulator or printed.
第１図では、上、下２基板しか示していないが、基板間
に上記の絶縁シートを挿入すれば基板は何枚でもよい。Although FIG. 1 only shows the upper and lower two substrates, any number of substrates may be used as long as the above-mentioned insulating sheet is inserted between the substrates.
ノイズが、上基板、下基板どちらかで発生すると、絶縁
物４．６を通シ抜けて金属５に当た９、ここでノイズを
遮断することによシ、上基板、下基板の相互干渉は起こ
らず、ノイズ誤動作しない。When noise occurs on either the upper or lower substrate, it passes through the insulator 4.6 and hits the metal 59, which blocks the noise and prevents mutual interference between the upper and lower substrates. will not occur, and there will be no noise malfunctions.

In addition, it is possible to prevent noise malfunctions by using an insulating sheet instead of taking such extensive measures as shielding each board individually to prevent noise malfunctions, which reduces costs.
