Abstract
An electrical connector includes a connector housing having a drain hole. A vacuum pump is connected to the drain hole through a suction pipe. The suction pipe is connected to a water trap. A control unit controls the vacuum pump on the basis of the state of a mode selecting switch and a reed switch detecting the state of a lid for closing and opening an open end of the connector housing. In mode A, the vacuum pump is actuated to aspirate water from in the connector housing with air while the lid is open. In mode B, the vacuum pump is actuated both when the lid is opened and when the lid is closed.
