Description
【０００１】[0001]
本考案は鉄道、自動車、航空機などに用いられる電子機器のように、常に振動 が印加される状態で使用されるものに適した補助回路基板支持構造に関するもの The present invention relates to an auxiliary circuit board support structure suitable for use in a state where vibration is always applied, such as electronic equipment used in railways, automobiles, aircrafts, etc.
【０００２】[0002]
従来の補助回路基板支持構造は、図５、図６に示すように、ケース６ｃの底面 に垂直配置され下端部をケース６ｃに固定された補助回路基板２ｃと水平配置さ れケース６ｃに固定された主回路基板１ｃを有し、補助回路基板２ｃ上の回路と 主回路基板１ｃ上の回路とは両基板間の所定のランド間を端子部１４により電気 的に接続されている。 前記補助回路基板２ｃはその下端部をＬ型形状の固定具 １２を介して固定ネジ１１とナット１３によりケース６ｃに固定されている。 As shown in FIGS. 5 and 6, the conventional auxiliary circuit board support structure is arranged vertically to the bottom surface of the case 6c and has its lower end fixed to the case 6c and the auxiliary circuit board 2c which is horizontally arranged and fixed to the case 6c. The main circuit board 1c is provided, and the circuit on the auxiliary circuit board 2c and the circuit on the main circuit board 1c are electrically connected by a terminal portion 14 between predetermined lands between the boards. The lower end of the auxiliary circuit board 2c is fixed to the case 6c by a fixing screw 11 and a nut 13 via an L-shaped fixing tool 12.
【０００３】[0003]
前述した補助回路基板支持構造では、補助回路基板２ｃの下端部だけが固定さ れているために、比較的低周波の自動車等の振動により補助回路基板２ｃが共振 し易く、補助回路基板２ｃに実装された部品７のリード端子に剪断応力が加わり リード端子が破断する問題がある。又主回路基板１ｃの固定部１９の上方は部品 実装が出来ないスペースになっている。本考案は、かかる点に鑑みてなされたも ので、その目的とするところは、主回路基板１ｃの固定部１９の上方のスペース を利用して、補助回路基板２ｃの上端部を保持し、自動車等の振動による補助回 路基板２ｃの共振を防ぐ補助回路基板支持構造の提供にある。 In the above-mentioned auxiliary circuit board supporting structure, since only the lower end portion of the auxiliary circuit board 2c is fixed, the auxiliary circuit board 2c is likely to resonate due to the vibration of an automobile or the like having a relatively low frequency. There is a problem that a shear stress is applied to the lead terminal of the mounted component 7 and the lead terminal breaks. A space above the fixing portion 19 of the main circuit board 1c cannot be used for component mounting. The present invention has been made in view of the above point, and the purpose thereof is to utilize the space above the fixing portion 19 of the main circuit board 1c to hold the upper end portion of the auxiliary circuit board 2c, It is to provide an auxiliary circuit board support structure for preventing resonance of the auxiliary circuit board 2c due to vibrations such as.
【０００４】[0004]
本考案の補助基板支持構造は、補助回路基板の保持を一端支持から両端支持に することにより補助回路基板の共振周波数を上昇させ、自動車等の通常の周波数 では共振をおこさない構成になる。 具体的には、ケース６ｃ内に垂直配置され 下端部を保持された補助回路基板２ｃと水平配置されケース６ｃに固定された主 回路基板１ｃを有し、主回路基板１ｃの固定部１９の上方の空間を利用して、補 助回路基板２ｃの上端部と主回路基板１ｃの固定部１９の上端部とを橋絡する支 持具を固定部１９を介してケース６ｃに固定することにより、補助回路基板２ｃ の上端部をケース６ｃに固定する。 The auxiliary circuit board support structure of the present invention increases the resonance frequency of the auxiliary circuit board by supporting the auxiliary circuit board from one end to both ends, and does not resonate at a normal frequency of an automobile or the like. Specifically, it has an auxiliary circuit board 2c which is vertically arranged in the case 6c and whose lower end is held, and a main circuit board 1c which is horizontally arranged and fixed to the case 6c and above the fixing portion 19 of the main circuit board 1c. By using the space of 2 to fix the supporting tool bridging the upper end of the auxiliary circuit board 2c and the upper end of the fixing portion 19 of the main circuit board 1c to the case 6c via the fixing portion 19, The upper end of the auxiliary circuit board 2c is fixed to the case 6c.
