PURPOSE:To certainly prevent an electric shock by leak by making the protruding amount of a plug edge as a grounding electrode larger than the protruding amounts of other plug edges. CONSTITUTION:A recessed part 13 is formed on the front surface of a housing 1, and three plug edges are protrudingly provided in the inner part thereof. A plug edge 15 forming a grounding electrode is mounted with a slippage so that it is protruded forward from the other plug edges 15. Thus, the protruding amount of the plug edge as the grounding electrode becomes large, so that it can be prevented only the plug edges 15 other than the plug edge 15 forming the grounding electrode from being connected to a harness connector when a harness plug is attached to and removed from the harness connector. Namely, when the harness plug is connected to the harness connector, the plug edge 15 as the grounding electrode is connected before the other plug edges 15 are connected to the harness connector. When the harness plug is removed from the harness connector, conversely, the plug edge 15 as the grounding electrode is connected after the other plug edges 15 are removed from the harness connector, and an electric shock by leak can be certainly prevented. |
