  • Patent number: 6896530
    Abstract: A housing body is formed with an opening, and a cavity communicated with the opening and into which a mating connector terminal inserted through the opening in a first direction is fitted. An internal terminal is provided in the cavity to be electrically connected to the mating connector terminal fitted into the cavity. A pair of shutter members are disposed outside the cavity such that a part of each of the shutter members is movable in a second direction which is perpendicular to the first direction, between a first position for concealing a part of the opening and a second position for revealing the part of the opening. An urging member urges each of the shutter members toward the first position, so that the mating connector terminal moves the shutter members toward the second position against an urging force of the urging member when the mating connector terminal is fitted into the cavity.
