TERMINAL BLOCK

To provide a waterproof structure for an externally exposed terminal block, having an insert-molded tabular bus bar, which is excellent in terms of space-saving, cost reduction, and a layout property.SOLUTION: A terminal block, which has achieved an improved layout property by insert-molding a tabular bus bar with a complicated shape, is provided such that it is exposed to the outside of a housing. A bus bar, for electrically connecting the tabular bus bar 4 in the terminal block to the inside of the housing, has a cylindrical shape. The cylindrical bus bar 12 has, at its tip end, an outer circumferentially chamfered part 16. The terminal block is provided with a second seal ring 17 such that it comes into contact with three surfaces of the tabular bus bar, the outer circumferentially chamfered part of the cylindrical bus bar, and mold resin of the terminal block.SELECTED DRAWING: Figure 3 【課題】省スペース化および低コスト化、レイアウト性の面で優れた平板バスバーがインサート成型された外部露出型端子台における防水構造を得る。【解決手段】複雑な形状の平板バスバーをインサートモールドすることでレイアウト性を向上させた端子台を筐体外部に露出するように設け、端子台の平板バスバー４と筐体内部を電気的に接続するバスバーを円筒形状とし、円筒バスバー１２の先端部に外周面取り部１６を設け、平板バスバーと円筒バスバー外周面取り部と端子台モールド樹脂の３面に接するように第２のシールリング１７を設けた端子台である。【選択図】図３
