PROBLEM TO BE SOLVED: To solve such a problem that, in a structure of a card edge connector used in an electronic control unit, the movement of a female connector terminal with a contact pressure on a circuit board when a female connector is fitted causes the generation of scraped powder or the like of the circuit board and the occurrence of peel-off of a terminal plating, and therefore conduction failure between the circuit board and the female terminal is caused.SOLUTION: A circuit board of an electronic control unit is formed stepwise so that the amount of contact movement of a female connector terminal is reduced and the size of a circuit board is reduced by reducing a terminal pitch interval.SELECTED DRAWING: Figure 5
【課題】電子制御装置で使用しているカードエッジコネクタの構造では、雌コネクタ勘合時に回路基板上を雌コネクタ端子が接圧を持って移動するため、回路基板の削れ粉等が発生することと、端子メッキの剥がれが発生し、回路基板と雌コネクタ端子間の導通不良が発生していた。【解決手段】電子制御装置の回路基板を階段状としたことにより、雌コネクタ端子の接触移動量の低減と、端子ピッチ間隔を縮小し回路基板の小型化をした。【選択図】図5
