Provided with a first connector part to connect a first cable, a second connector part to connect a second cable, and to fit with a first connector part, thereby ensuring electrical connection between a first cable and a second cable, and a housing to hold a second connector part rotatably around an axial direction of a second cable.

Connector

A cooling apparatus cools a battery and a DC/DC converter. In a duct, a battery cooling fan having a great rated capacity is installed. The duct branches into a battery-side intake duct and a DC/DC converter-side intake duct on the downstream side of the battery cooling fan. In the battery-side intake duct, the battery is installed to received cooling air. In the DC/DC converter side intake duct, the DC/DC converter is installed to receive cooling air. A DC/DC converter cooling fan having a small rated capacity is installed directly upstream of the DC/DC converter. An ECU controls the two cooling fans based on the temperature of the battery and the DC/DC converter.

In-vehicle device cooling apparatus

In the vehicle of the invention, when the temperature of an inverterfor driving a motor MGlinked to front wheelsandreaches or exceeds a preset restriction start temperature, the drive control of the invention controls the invertersandto gradually decrease the output torque of the motor MGsimultaneously with a gradual increase in output torque of a motor MGwhich is linked to rear wheelsandSuch torque control ensures output of a torque demand required for the vehicle. When the temperature of the inverterreaches or exceeds a preset frequency switchover temperature, which is higher than the restriction start temperature, the drive control of the invention controls the invertersandto lower a switching frequency of transistors Tto Tin the inverterand to ensure output of the torque demand. Such drive control effectively relieves the load of the inverterwhile decreasing the frequency of lowering the switching frequency of the inverterThis arrangement thus desirably attains both prevention of overheat of the inverterand reduces the switching noise.

Power output apparatus, motor vehicle equipped with power output apparatus, and control method of power output apparatus

An electronic component housing structural body includes a first housing body accommodating electronic components and a second housing body accommodating electronic components. Fitting plane of the first and second housing bodies include a liquid passage area and a communicating passage area. The liquid passage area includes a cooling passage in which cooling liquid flows. The communicating passage area includes a communicating passage that connects housing chambers of the first and second housing bodies. Furthermore, a single sealing member is disposed on the fitting plane to independently surround and seal the liquid passage area and the communicating passage area.
