US Patent 9024183 Seal cover for in-vehicle electric device

A seal cover includes a cover main body (10) shaped to cover an opening of a case and to be attached to a surface of the case. A seal ring holder (20A) is on the underside of the cover main body (10) and is arranged to fit into the opening. A seal ring (25) is on the outer peripheral surface of the seal ring holder (20A) and closely contacts the inner peripheral surface of the opening. An interlock connector (40) projects from the seal ring holder (20A) for connecting to the waiting connector and sets an energizing circuit in an energized state or a non-energized state upon being connected to or separated from the waiting connector. The interlock connector (40) is mounted on the seal ring holder (20A) to be movable in a direction perpendicular to a connecting direction to the waiting connector.
