本発明は、安全対策を講じた回路基板に関する。   The present invention relates to a circuit board in which safety measures are taken.

従来、車両においては、室内のインストルメントパネルにカーナビやオーディオのスイッチノブなどの部品を配設している。衝突安全性の観点から、自動車法規のECEなどによると、突起(ECEでは、インストルメントパネルから9.5mm以上の高さをもった部品)は、ある荷重である高さまで引っ込む、あるいは離脱するように設計しなければならない。ボリュームノブなどの部品は、操作性を考慮するとある程度の高さを必要とするが、しかし、上記法規の規制対象としないためには、高さを低く設計しなければならず、この場合には、操作性に劣り、またデザインの制約がある。   Conventionally, in a vehicle, parts such as a car navigation system and an audio switch knob are arranged on an indoor instrument panel. From the viewpoint of collision safety, according to ECE of automobile regulations, the protrusions (in ECE, parts having a height of 9.5 mm or more from the instrument panel) are retracted to a certain load height or detached. Must be designed to Parts such as the volume knob require a certain height in consideration of operability, but in order to avoid the restriction of the above regulations, the height must be designed low. It is inferior in operability and has design restrictions.

この対策として、従来、図9及び図10に示すように、基板本体1において部品2の配設領域Eを一部を除いて取り囲むようにスリット3を形成する構成とした回路基板4がある。なお上記部品2としてはボリュームなどである。この回路基板4は、カーナビゲーションなどのパネル5の裏側に設けられており、上記部品2がこのパネル5から突出している。   Conventionally, as a countermeasure, there is a circuit board 4 in which a slit 3 is formed so as to surround a part 2 of the board body 1 except for a part thereof, as shown in FIGS. 9 and 10. The component 2 is a volume or the like. The circuit board 4 is provided on the back side of a panel 5 such as a car navigation system, and the component 2 protrudes from the panel 5.

このものでは、衝突時などにおいて運転者の頭などが部品2に衝当したときに、基板本体1の配設領域E部分が折れ曲がり、あるいは欠落して、この部品2が陥没し、もって衝突時の安全性が図られる。
また、本発明とは直接関係ないが、回路基板に実装された部品に、落下時などの衝撃の伝播を抑える構成として、特許文献1がある。
