CIRCUIT BOARD AND ELECTRIC POWER SUPPLY

PROBLEM TO BE SOLVED: To reliably solder a connection terminal to a bus bar without deteriorating the physical strength or increasing the size of a circuit board main body.SOLUTION: An electric power supply comprises: a circuit board main body 10; bus bars 12 and 13 provided to a component mounting surface Fa side of the circuit board main body 10; and a capacitor 11 which is provided to the component mounting surface Fa side of the circuit board 10, and in which connection terminals 11b and 11c are soldiered to component connecting end parts 23 and 33 of the bus bars 12 and 13. An insertion hole 10c which allows the component connecting end parts 23 and 33 to be inserted is provided to the circuit board main body 10, insertion holes 23a and 33a which allow the connection terminals 11b and 11c to be inserted are provided to the component connecting end parts 23 and 33. The bus bars 12 and 13 are fixed to the circuit board main body 10 in a state where the component connection end parts 23 and 33 are inserted into the insertion hole 10c so that a soldering surface Fc on the side where the connection terminals 11b and 11c inserted into the insertion holes 23a and 33a are projected is positioned on a back surface Fb side than the component mounting surface Fa.SELECTED DRAWING: Figure 4 【課題】基板本体の物理的強度の低下や大形化を招くことなく、バスバーに対して接続端子を確実に半田付けする。【解決手段】基板本体１０、基板本体１０の部品実装面Ｆａ側に配設されたバスバー１２，１３、および基板本体１０の部品実装面Ｆａ側に配設されると共にバスバー１２，１３の部品接続用端部２３，３３に接続端子１１ｂ，１１ｃが半田付けされたコンデンサ１１を備え、基板本体１０には、部品接続用端部２３，３３を挿入可能な挿入孔１０ｃが設けられ、部品接続用端部２３，３３には、接続端子１１ｂ，１１ｃを挿通可能な挿通孔２３ａ，３３ａが設けられ、バスバー１２，１３は、挿通孔２３ａ，３３ａを挿通させた接続端子１１ｂ，１１ｃが突出する側の半田付け面Ｆｃが部品実装面Ｆａよりも裏面Ｆｂ側に位置するように部品接続用端部２３，３３が挿入孔１０ｃに挿入された状態で基板本体１０に固定されている。【選択図】図４
