To provide a cable connection structure capable of suppressing intrusion of water into a connection portion between a connector portion of an electric device and a connector portion of a cable arranged outside a vehicle interior.SOLUTION: A power conversion unit 30 and a DC cable 51 are connected to each other by fitting connectors 60 and 70 to each other. The unit-side connector 60 includes a connector-side tubular portion 63 and an abutting portion 63a which is provided to the connector-side tubular portion 63 and abuts against the cable-side connector 70. The cable-side connector 70 includes a receiving portion 71a that comes into contact with the abutting portion 63a, and a cable-side tubular portion 71b that further protrudes from the receiving portion 71a and covers the connector-side tubular portion 63 from an outer peripheral side through a predetermined gap in a radial direction. An outer peripheral surface of the connector-side tubular portion 63, an inner peripheral surface of the cable-side tubular portion 71b, and a surface of a space S1 compartmentalized by the receiving portion 71a have water repellency.SELECTED DRAWING: Figure 5
【課題】車室外に配置される電気デバイスのコネクタ部とケーブルのコネクタ部の接続部に水が浸入するのを抑制可能なケーブル接続構造を提供する。【解決手段】電力変換ユニット30と直流ケーブル51とは、互いのコネクタ60、70を嵌合することで接続される。ユニット側コネクタ60は、コネクタ側筒部63と、コネクタ側筒部63に設けられケーブル側コネクタ70に当接する突き当て部63aと、を備える。ケーブル側コネクタ70は、突き当て部63aと当接する受け部71aと、受け部71aからさらに突出し、径方向において所定の隙間を介してコネクタ側筒部63を外周側から覆うケーブル側筒部71bと、を備える。コネクタ側筒部63の外周面、ケーブル側筒部71bの内周面、及び受け部71aで区画形成される空間S1の表面は、撥水性を有する。【選択図】図5
