Connector device

A connector device comprising a connector and a mating connector mateable with each other, wherein:

• the connector comprises a housing, a power terminal, a sub-housing and a detection terminal;
• the power terminal is held by the housing;
• the detection terminal is held by the sub-housing;
• the sub-housing is supported by the housing and is movable relative to the housing;
• the mating connector comprises a mating housing, a mating power terminal and a mating detection terminal;
• the mating power terminal and the mating detection terminal are held by the mating housing;
• the housing is formed with an axis portion;
• the mating housing is formed with a mating axis portion;
• one of the axis portion and the mating axis portion is a shaft, and a remaining one of the axis portion and the mating axis portion is a bearing;
• the shaft extends in an axial direction;
• under a state where the shaft and the bearing are combined with each other, the housing is turnable about the shaft relative to the mating housing;
• a turn of the housing relative to the mating housing changes a state of the connector between an unconnected state and a connected state via an intermediate state;
• when the connector takes the unconnected state, the power terminal is unconnected to the mating power terminal, and the detection terminal is unconnected to the mating detection terminal;
• when the connector takes the intermediate state, the power terminal is connected to the mating power terminal, but the detection terminal is unconnected to the mating detection terminal;
• when the connector takes the connected state, the power terminal is connected to the mating power terminal, and the detection terminal is connected to the mating detection terminal;
• the sub-housing has a guided portion;
• the mating housing has a guide portion;
• and
• while the state of the connector is changed from the intermediate state to the connected state, the guide portion guides the guided portion to move the sub-housing relative to the housing, so that the detection terminal is moved downward along an upper-lower direction perpendicular to the axial direction to be connected to the mating detection terminal.
