To secure normal operation by suppressing an influence due to dew condensation or freezing even in the case where a vehicle is used in an environment such as a cold district.SOLUTION: In an electric connection box 10, two type of relays such as PCB relay modules 12 and 13 or plug-in relays 14 to 17 are mounted. A power source supply to a load of an engine start system on-vehicle device 31 that requires a countermeasure on dew drop and freezing is controlled by the PCB relay module 12. In a circumference of an electric coil as a heat source in the PCB relay module 12, since a change of a heat distribution becomes looseness, normal operation can be secured because the dew drop hardly occurs even in the case of high humidity. In the load that the countermeasure on the dew drop is not important, the power source supply is controlled by using the plug-in relay or the like.SELECTED DRAWING: Figure 1

    【課題】車両が寒冷地などの環境で使用される場合でも結露や凍結による影響を抑制し正常動作を担保すること。【解決手段】電気接続箱10内にPCBリレーモジュール12、13や、プラグインリレー14~17などの2種類のリレーを搭載した。結露および凍結の対策を必要とするエンジン始動系車載機器31などの負荷に対する電源電力供給は、PCBリレーモジュール12により制御する。PCBリレーモジュール12内の熱源である電気コイルの周辺で熱分布の変化が緩やかになるため、湿度が高い場合でも結露が生じにくくなり正常動作を担保できる。結露対策が重要でない負荷については、プラグインリレーなどを用いて電源電力供給を制御する。【選択図】図1
