ELECTRONIC CONTROL DEVICE

To provide a highly reliable electronic control device which can inhibit influence of vibration on a connection part between a transformer terminal and a printed circuit board.SOLUTION: An electronic control device has: a substrate provided with a circuit; a transformer provided on the substrate; and a case to which the substrate is fixed. The substrate is located between the transformer and the case, and the transformer is provided with: a transformer fixing part which penetrates through the substrate and fixes the transformer to the case; and a terminal which penetrates through the substrate from the transformer and is provided toward the case. The substrate is provided with a connection member which electrically connects the terminal with the circuit. The terminal is provided with an insertion stopper which inhibits movement of the terminal to the case side.SELECTED DRAWING: Figure 3 【課題】トランス端子とプリント基板の接続部への振動の影響を抑制可能な信頼性の高い電子制御装置を提供する。【解決手段】回路が設けられた基板と、前記基板上に設けられたトランスと、前記基板が固定されたケースと、を有し、前記基板は前記トランスと前記ケースの間に位置し、前記トランスには、前記基板を貫通して前記トランスと前記ケースとを固定するトランス固定部と、前記トランスから前記基板を貫通して前記ケースに向かって設けられた端子が設けられており、前記基板には、前記端子と前記回路とを電気的に接続する接続部材が設けられ、前記端子には、前記端子の前記ケース側への動きを抑制する挿入留めが設けられた電子制御装置。【選択図】 図３
