【発明の詳細な説明】 産業上の利用分野 本発明は、プリント基板の固定装置に関するものであ
る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board fixing device.
従来の技術 従来のプリント基板の固定は、第３図のように、取付部
２に設けられた溝部３に第２図のようなプリント基板を
合わせて挿入し、固定部の別の位置に設けられた爪部に
より、溝と爪により位置を決め固定していた。2. Description of the Related Art As shown in FIG. 3, a conventional printed circuit board is fixed by inserting a printed circuit board as shown in FIG. 2 into a groove portion 3 provided in a mounting portion 2 and providing it at another position of the fixing portion. With the claws thus formed, the position was fixed and fixed by the groove and the claw.
発明が解決しようとする課題 しかし、このような構造では、プリント基板のミシン目
部が第４図２（ａ），（ｂ）のように不規則に割れる事
があり、この分のバラツキを考えてプリント基板と取付
部分の寸法を決めるとどうしても固定部におけるプリン

受信素子等が取付けられたプリント基板は、前記のガタ
ツキによる位置ズレが発生するという問題があった。However, in such a structure, the perforation portion of the printed circuit board may be irregularly cracked as shown in FIGS. 4 (a) and 2 (b) of FIG. If the dimensions of the printed circuit board and the mounting part are decided by any means, there is a great deal of rattling of the printed circuit board in the fixed part, and especially the printed circuit board on which the switch, remote control receiving element, etc. are mounted is subject to positional deviation due to the rattling. there were.
これは下記の理由による。This is for the following reason.
つまり、プリント基板５は生産性・コスト面から第５図
のように複数枚のプリント基板が同時に形成され、そこ

シン目７にそって分割され、１枚のプリント基板とな
る。その時、ミシン目中央で割れずにミシン目すべてが
残るプリント基板が発生する。また逆にミシン目のない
プリント基板という場合も発生する。In other words, the printed circuit board 5 is formed from a plurality of printed circuit boards at the same time as shown in FIG. 5 from the viewpoint of productivity and cost, and after parts are attached thereto, the printed circuit board 5 is divided along the perforations 7 which are pre-pressed, It becomes one printed circuit board. At that time, a printed circuit board in which all the perforations remain without being broken at the center of the perforations occurs. On the contrary, a printed circuit board without perforations may occur.
すなわちミシン目のないプリント基板寸法が最小でミシ
ン目がすべて残るプリント基板寸法が最大となり、その
差を含んで取り付け部の寸法を設計しなければならな
い。またこの差がガタツキとして発生してくるのであ
る。In other words, the size of the printed circuit board without perforations is the smallest and the size of the printed circuit board with all the perforations is the largest, and the size of the mounting portion must be designed including the difference. Moreover, this difference occurs as rattling.
課題を解決するための手段 上記問題点を解決する本発明の手段は、上記固定用ミゾ
部の内側にミシン目部分をさけて凸起を設け、プリント
基板のミシン目部以外の面と凸起を当てて位置決めを行
うものである。Means for Solving the Problems The means of the present invention for solving the above-mentioned problems is to provide a protrusion inside the fixing groove portion to avoid a perforation portion, and to form a protrusion on a surface other than the perforation portion of a printed circuit board. Positioning is performed by applying.
作用 本発明の作用は次のようになる。Action The action of the present invention is as follows.
すなわち、ミシン目以外の面はプレス加工により精度が
出ているためこの面を利用し溝部の凸起を当てて位置を
決め、さらに溝の深さをミシン目の割れ方が最大となる
時の寸法より大きくすればミシン目による影響がない。
この結果、部品取付後プリント基板を割った時、ミシン
目部分が最小〜最大とどのようになろうともプレス加工
時につくられた面により位置決めすることで、ガタツキ
を最小限に押え、ミシン目による固定位置決めのバラツ
キをなくす事ができるのである。That is, since the surface other than the perforations is highly pressed, the surface is used to determine the position by applying the convexity of the groove, and the depth of the groove should be the maximum when the cracking of the perforation becomes maximum. If it is larger than the size, it will not be affected by the perforation.
As a result, when the printed circuit board is broken after the parts are attached, the backlash is minimized by positioning with the surface created during press work, no matter what the perforation is from the smallest to the largest. It is possible to eliminate variations in fixed positioning.

た受信性能も安定向上するなど種々の効果を奏する。EFFECTS OF THE INVENTION As described above, according to the present invention, as compared with the related art, the printed circuit board is not fixedly positioned at the perforated portion, but is fixedly positioned by the pressed surface, so that variations in perforation of the perforation can be prevented. Fixed positioning is possible without being affected. Since the rattling at this time is suppressed by the error at the time of press working, the accuracy is several steps better than before. Therefore, various effects can be obtained such that the reception performance, which has been conventionally caused by the deviation due to the rattling of the receiving unit, is stably improved.
