Patent ID: 7645145

Claim:
A composite plug comprising a plurality of plugs, each plug equipped with two conductive pieces connected with each other by a conductive member, the plug causing two circuit terminals included in an electric circuit be in a conductive state with each other by making the two conductive pieces contact with the two circuit terminals, respectively, the plug causing the two circuit terminals included in the electric circuit be in a nonconductive state with each other by making the two conductive pieces be separated from the two circuit terminals, respectively, wherein a first plug, being one of the plurality of plugs, causes two circuit terminals included in a first power circuit to be in a conductive state or a nonconductive state with each other, the first power circuit supplying electric power to a motor for driving a vehicle; a second plug other than the first plug, the second plug being one of the plurality of plugs, causes two circuit terminals included in a second power circuit to be in a conductive state or a nonconductive state with each other, the second power circuit provided separately from the first power circuit in order to increase the electric power to be supplied to the motor; and the plurality of plugs are fixed to a shared fixing member.
